On solving the provided question, we can say that - the valuye os the complementary angle is 83.0000000004.

When two angles add up to 90 degrees, they are said to be complimentary. When two angles add up to 180 degrees, they are said to be subservient. . When the sum of two angles equals 90 degrees, they are called complementary angles. For example, 30 and 60 degrees are supplementary angles. A supplementary angle is two angles that add up to 180 degrees, and a supplementary angle is two angles that add up to 90 degrees. of 30 and 60 degrees are supplementary. A supplementary angle is two angles combined to make a 180 degree angle, while a supplemental angle is two angles combined to make a 90 degree angle. Two angles are referred to as complimentary if their total is 90 degrees. Alternatively said, a right angle is created by the complementary angles (90 degrees).

here we have

(12x + 7) = 90

12x = 83

x= 6.9166666667

12x = 83.0000000004

Answer:

\(x=4; \ y=\frac{8}{\sqrt{3}}.\)

Step-by-step explanation:

1) in the triangle with the angles 45; 90 and 45°: x=4√2/√2=4;

2) in the triangle with the angles 60; 90 and 30°: y=x/sin60°= 4/(√3/2)=8/√3

Answer:

x = 32 y=\(\frac{8}{\sqrt{3} }\)

Step-by-step explanation:

solving for x

take 45 degree as reference angle

using sin rule

sin 45 = opposite / hypotenuse

\(\frac{1}{\sqrt{2} } = \frac{x}{4\sqrt{2} }\)

do cross multiplication

\(4\sqrt{2} * 1 = x * \sqrt{2}\)

\(\frac{4\sqrt{2} }{\sqrt{2} } = x\)

root 2 and root 2 gets cancel.Then ,

x = 4

solving for y

take 60 degree as reference angle

using sin rule

sin 60 = opposite / hypotenuse

\(\frac{\sqrt{3} }{2} = \frac{x}{y}\)

just now we found the value of x i.e 4 now substitute the value of x here.

\(\frac{\sqrt{3} }{2} = \frac{4}{y}\)

do cross multiplication

\(2*4 = y * \sqrt{3}\)

\(\frac{8}{\sqrt{3} } = y\)

The constant of proportionality between 'y' and 'x' in the graph is 0.20

The constant of proportionality of a proportional relationship between two variables, x and y, can be defined as the ratio of y to x, which is expressed as, k = y/x, where x and y are the coordinates of one point one the line that represents the proportional relationship.

When two quantities are directly proportional, then a percentage increase in one of the quantities that will result in an equal percentage increase in the other quantity, and the two quantities are therefore, increasing at the same rate to each other.

Using the coordinates of a point on the graph, (5, 1), find the constant of proportionality, k:

Constant of proportionality (k) = y/x = 1/5

Constant of proportionality (k) = 0.20

Therefore, the constant of proportionality that represents the proportional relationship between the variables, x and y, is calculated as, 0.20.

The statement that is true is "the study is observational and lacks control of too many lurking variables" and "the study should be replicated with other populations."Here are the reasons why:

The study is observational and lacks control of too many lurking variables:

This statement is true since the study was done with people who used turmeric in the meals they consume. There are a lot of things that could affect the difference in mileage walked by the turmeric users compared to those who do not consume it. For instance, the intensity of exercise, lifestyle, and overall diet could have been contributing factors. Thus, there is no guarantee that turmeric is solely responsible for the difference in miles walked.

The study should be replicated with other populations:

This statement is true since the study was carried out with a small sample size and in one geographic location. This means that there is a possibility that the results were just unique to that region. Replicating the study in a different location would help to establish the generalizability of the results and whether or not they are consistent across populations.

The trapezoidal rule is a numerical integration method that uses trapezoids to estimate the area under a curve. The trapezoidal rule can be used for both definite and indefinite integrals. The trapezoidal rule approximation, Tn, to the integral sin r dz is given by:

Tn = (b-a)/2n[f(a) + 2f(a+h) + 2f(a+2h) + ... + 2f(b-h) + f(b)]where h = (b-a)/n. To determine how large n should be so that Tn is accurate to within 0.00001, we can use the error bound given in Section 5.9 of the course text. According to the error bound, the error, E, in the trapezoidal rule approximation is given by:E ≤ ((b-a)³/12n²)max|f''(x)|where f''(x) is the second derivative of f(x). For the integral sin r dz, the second derivative is f''(r) = -sin r. Since the absolute value of sin r is less than or equal to 1, we have:max|f''(r)| = 1.

Substituting this value into the error bound equation gives:E ≤ ((b-a)³/12n²)So we want to choose n so that E ≤ 0.00001. Substituting E and the given values into the inequality gives:((b-a)³/12n²) ≤ 0.00001Simplifying this expression gives:n² ≥ ((b-a)³/(0.00001)(12))n² ≥ (b-a)³/0.00012n ≥ √(b-a)³/0.00012Now we just need to substitute the values of a and b into this expression. Since we don't know the upper limit of integration, we can use the fact that sin r is bounded by -1 and 1 to get an upper bound for the integral.

For example, we could use the interval [0, pi/2], which contains one full period of sin r. Then we have:a = 0b = pi/2Plugging in these values gives:n ≥ √(pi/2)³/0.00012n ≥ 5073.31Since n must be an integer, we round up to the nearest integer to get:n = 5074Therefore, we should choose n to be 5074 so that the trapezoidal rule approximation, Tn, to the integral sin r dz is accurate to within 0.00001.

The shape of the cable that supports a bridge with constant horizontal density can be described by a catenary curve.

A catenary curve is the shape that a flexible, uniform cable or chain takes when it is freely hanging under its own weight and uniform horizontal loading. In this case, since the cable has negligible density (w≡0), it means that the cable has no weight and is only subjected to the horizontal loading caused by the bridge.

The equation that describes a catenary curve is given by:

y = a cosh(x/a)

where y is the vertical coordinate, x is the horizontal coordinate, and a is a constant related to the tension in the cable and the horizontal density of the bridge.

In the given scenario, since the horizontal density of the bridge is constant (L(x)≡L0), the equation for the shape of the cable would be:

y = a cosh(x/a)

where a is a constant determined by the specific conditions and properties of the bridge.

Therefore, the shape of the cable supporting the bridge with constant horizontal density is described by a catenary curve.

The method for finding and classifying critical points of a function involves finding the first derivative of the function and setting it equal to zero to find the critical points. Then, the second derivative test is used to classify the critical points as local maxima, local minima, or saddle points.

The given function is not provided in the question. Therefore, we cannot find and classify the critical points of the function. However, I can provide the general method for finding and classifying critical points of a function.

Finding the critical points: To find the critical points of a function, we need to find the values of x where the first derivative of the function is equal to zero or does not exist. These points are called critical points. Mathematically, we can express this as follows:

f′(x) = 0 or f′(x) does not exist

Classifying the critical points: Once we have found the critical points of the function, we can classify them using the second derivative test. This test involves finding the second derivative of the function at the critical points and determining its sign.

If the second derivative is positive, then the critical point is a local minimum. If the second derivative is negative, then the critical point is a local maximum. If the second derivative is zero or undefined, then the critical point is a saddle point.

Mathematically, we can express this as follows:

f′′(x) > 0, then (x, f(x)) is a local minimum.
f′′(x) < 0, then (x, f(x)) is a local maximum.
f′′(x) = 0 or does not exist, then (x, f(x)) is a saddle point.

Once we have found and classified the critical points of the function, we can then enter the list of ordered pairs (x, y) where the max/min/saddle occurs for each classification. If there are no points for a classification, we enter "dne" (does not exist).

Step-by-step explanation:

Since λa + ub is parallel to ha + tb, we can write:

λa + ub = k(ha + tb)

where k is some constant. We can simplify this equation by expanding both sides:

λa + ub = kha + ktb

Rearranging the terms, we get:

λa - kha = ktb - ub

Factoring out a, we get:

a(λ - kh) = b(kt - u)

Since a and b are non-parallel, they are linearly independent, which means that a and b are not multiples of each other. This also means that the only way for the left side of the equation to be equal to 0 is if λ - kh = 0, or λ = kh. Similarly, the only way for the right side of the equation to be equal to 0 is if kt - u = 0, or u/t = k/h.

Therefore, we have shown that λ/h = u/t.

The numerical value of x in the expression 9x+18 is 14.

A regular decagon has ten (10) sides and ten interior angles.

The sum of the measures of the interior angles of a polygon with n sides is given by the formula:

Sum of interior angles = (n - 2) × 180 degrees

For a regular decagon, n = 10, so the sum of the interior angles is:

Sum of interior angles = (10 - 2) × 180

= 8 × 180

= 1440 degrees

Since all the interior angles of a regular polygon have the same measure, we can divide this sum by 10 to find the measure of each interior angle:

Measure of each interior angle = Sum of interior angles / Number of sides

= 1440 / 10

= 144 degrees

Now, we can use the given expression for one of the interior angles and solve for x:

9x + 18 = 144

9x = 144 - 18

9x = 126

x = 126/9

x = 14

Therefore, the value of x is 14.

When interpreting the expression as \((tanx)^{(sinx)\), the limit using L'Hospital's Rule is -∞ as x approaches 0+. However, when interpreting the expression as\(tan(x^{sinx})\), the limit is not well-defined due to the indeterminate form of 0^0.

To calculate the limit using L'Hospital's Rule, let's consider both interpretations of the expression and find the limits for each case:

Case 1: lim\((tanx)^{(sinx)\) as x approaches 0+

Taking the natural logarithm of the expression, we have:

\(ln[(tanx)^{(sinx)}] = sinx * ln(tanx)\)

Now, we can rewrite the expression as:

\(lim [sinx * ln(tanx)]\)as x approaches 0+

Applying L'Hospital's Rule, we differentiate the numerator and denominator:

\(lim [(cosx * ln(tanx)) + (sinx * sec^{2}(x))] / (1 / tanx)\) as x approaches 0+

Simplifying the expression:

\(lim [cosx * ln(tanx) + sinx * sec^{2}(x)] * tanx\) as x approaches 0+

\(lim [cosx * ln(tanx) + sinx * sec^{2}(x)] * (sinx / cosx)\) as x approaches 0+

\(lim [(cosx * ln(tanx) + sinx * sec^{2}(x)) / cosx] * sinx\) as x approaches 0+

\(lim [ln(tanx) + (sinx / cosx) * sec^{2}(x)] * sinx\) as x approaches 0+

\(lim [ln(tanx) + tanx * sec^{2}(x)] * sinx\) as x approaches 0+

Since lim ln(tanx) as x approaches 0+ = -∞ and\(lim (tanx * sec^{2}(x))\) as x approaches 0+ = 0, we have:

\(lim [ln(tanx) + tanx * sec^{2}(x)] * sinx\) as x approaches 0+ = -∞

Therefore, the limit of \((tanx)^{(sinx)\) as x approaches 0+ using L'Hospital's Rule is -∞.

Case 2: lim\(tan(x^{sinx})\)as x approaches 0+

We can rewrite the expression as:

lim\(tan(x^{(sinx)})\) as x approaches 0+

This expression does not have an indeterminate form of \(0^0\), so we do not need to use L'Hospital's Rule. Instead, we can substitute x = 0 directly into the expression:

lim \(tan(0^{(sin0)})\) as x approaches 0+

lim\(tan(0^0)\)as x approaches 0+

The value of \(0^0\) is considered an indeterminate form, so we cannot determine its value directly. The limit in this case is not well-defined.
