Answer:

365.76 cm in 12 feet

Step-by-step explanation:

Start by setting up two fractions which are equal to one another. We will use x as the unknown amount, which is the number of centimeters in 12 feet here.(see attached picture for a visual)

Now we can cross multiply, which gives us 12*60.96=2*x

Now, solving for x we divide 12*60.96=731.52 by 2, which gives us x=365.76 centimeters in 12 feet.

Answer:

See pic below.

Step-by-step explanation:

The equation 38.28 + 0.42x = C will be used to represent te cost or bill of the rental car driven.

An equation is a mathematical statement that contains the symbol "equal to" between two expressions with identical values.

As in 3x + 5 = 15, for example.

There are many different types of equations, including linear, quadratic, cubic, and others.

The three primary forms of linear equations are point-slope, standard, and slope-intercept.

So, we know that:

An initial fee for the rental car: $38.28

Then, charge for every extra mile: $0.42 per mile

The number of miles driven is x.

Then C cost would be:

38.28 + 0.42x = C

Therefore, the equation 38.28 + 0.42x = C will be used to represent te cost or bill of the rental car driven.

Answer:92.

Step-by-step explanation:

Answer:

x= -7/2

y= 5/4

Step-by-step explanation:

x-2y=-11

x+2y = -6

then isolate x and set equal to each other

Rounding to four decimal places, the standard divisor is 3.4792.

The standard divisor can be calculated as follows:

Standard Divisor = Total number of schools / Total number of upgrades

Total number of schools = 104 + 33 + 26 + 4 = 167

Total number of upgrades = 48

Standard Divisor = 167 / 48 = 3.4792

Rounding to four decimal places, the standard divisor is 3.4792.

The standard divisor is a term used in resource allocation or distribution problems, where a set number of resources (e.g., funding, personnel, supplies, etc.) has to be divided among a number of recipient entities (e.g., schools, departments, regions, etc.).

Given,

Sides of triangle ABC = 10.2cm, 17.5cm and 15.3cm

As we know,

Perimeter of a triangle = a + b + c

The distance from the initial point to the corner pocket is 164 cm.

The angle between the path as the ball approaches the rail and the path after it strikes the rail is 45 degrees.

We know that the ball traveled 100cm before ricocheting off the rail and another 120cm into the corner pocket.

We can use the Pythagorean Theorem to find the distance from where the cue initially struck the ball to the corner pocket.

Let x be the distance from the initial point to the corner pocket.

x^2 = 100^2 + 120^2 - 2100120*cos(45^{\circ})

x = \sqrt{28000} = \sqrt{700*40} = \sqrt{28000} = 164.856

Answer: Non proportional

Step-by-step explanation:

To know if the values given are proportional or not, we will use the formula:

y = kx

where

y = number of organisms

x = number of minutes

k = constant of proportionality

After 5 minutes, a bacteria colony has 1.3 million organisms. Using the formula, y = kx

1,300,000 = 5k

k = 1,300,000 / 5

k = 260,000

After 12 minutes, the same colony has 41.5 million organisms. Using y= kx

41,500,000 = 12x

x = 41500000 / 12

x = 3458333.8

After 15 minutes, the colony has grown to 101.3 million organisms.

y = kx

101,300,000 = 15k

k = 101,300,000 / 15

k = 6753333.8

It is a non-proportional relationship as the constant of proportionality is different for each.

In a case whereby a ball is thrown downward from the top of a 140​-foot building with an initial velocity of 16 feet per second. the time the ball is thrown will it strike the​ ground at t = 2.5 or -3.5.

Height of building = 140 ft

Initial velocity, u = 16 ft/sec

the equation given is

h = -16t² -16t +140

h(t) = -16t² -16t +140

AT h(t) = 0 , We can divide by -2 and have

To reparametrize the curve with respect to arc length, we need to find the arc length function s(t) and then invert it to get t(s). Then we can substitute t(s) into the original curve to get a new parametrization in terms of arc length.

First, we need to find the arc length function s(t). The arc length of a curve r(t) from t=a to t=b is given by the formula:

s(b) - s(a) = ∫[a,b] ||r'(t)|| dt

where ||r'(t)|| is the magnitude of the derivative of r(t) with respect to t. In this case, we have:

r(t) = e^(2t) cos(2t) i + 4 j + e^(2t) sin(2t) k

r'(t) = 2e^(2t) cos(2t) i - 2e^(2t) sin(2t) j + 2e^(2t) cos(2t) k

||r'(t)|| = √( (2e^(2t) cos(2t))^2 + (-2e^(2t) sin(2t))^2 + (2e^(2t) cos(2t))^2 )

= 2e^(2t) √( cos^2(2t) + sin^2(2t) + cos^2(2t) )

= 2e^(2t) √( 2cos^2(2t) + 1 )

Now we can integrate ||r'(t)|| with respect to t:

s(t) = ∫[0,t] ||r'(u)|| du

= ∫[0,t] 2e^(2u) √( 2cos^2(2u) + 1 ) du

This integral does not have a closed-form solution, so we need to use numerical methods to compute it. We can use the trapezoidal rule with a small step size Δt to get an approximation:

s(t) ≈ ∑[k=1,n] ( Δt/2 ) [ ||r'(t_k)|| + ||r'(t_{k-1})|| ]

where t_k = kΔt and n = t/Δt.

Now we need to invert s(t) to get t(s). Since s(t) is an increasing function of t, its inverse t(s) exists and is also an increasing function. We can use the bisection method or Newton's method to find t(s) numerically.

Finally, we can substitute t(s) into the original curve r(t) to get the new parametrization in terms of arc length:

r(s) = e^(2t(s)) cos(2t(s)) i + 4 j + e^(2t(s)) sin(2t(s)) k

Note that this is an implicit formula for r(s), since t(s) is itself a function of s.

Answer: 28 miles per hour

Step-by-step explanation:

224 miles / 8 hours=

224/8= 28 miles per hour

By consistently depositing $10,000 each year for 5 years at an interest rate of 8%, you would accumulate around $48,786.15.

Over a period of 5 years, assuming an annual deposit of $10,000 at an interest rate of 8%, you would accumulate a significant amount through compound interest.

To calculate the total amount after 5 years, we can use the formula for the future value of an ordinary annuity:

\( FV = P \times \left( \frac{{(1 + r)^n - 1}}{r} \right) \)

Where:

FV = Future value

P = Annual deposit

r = Interest rate per period

n = Number of periods

In this case, the annual deposit is $10,000, the interest rate is 8% (or 0.08 as a decimal), and the number of periods is 5 years. Plugging these values into the formula:

\( FV = 10000 \times \left( \frac{{(1 + 0.08)^5 - 1}}{0.08} \right) \)

After evaluating the expression, the future value (FV) after 5 years would be approximately $48,786.15.

Therefore, by consistently depositing $10,000 each year for 5 years at an interest rate of 8%, you would accumulate around $48,786.15. This demonstrates the power of compounding interest over time, where regular contributions can lead to significant growth in savings.

Step-by-step explanation:

In order to find the magnitude of a vector with three components, use the formula:

|V| = sqrt(Vx^2 + Vy^2 + Vz^2)

where Vx, Vy, and Vz are the components of the vector along the x, y, and z axes respectively.

To find the magnitude, you need to square each component, sum the squared values, and take the square root of the result. This gives you the length of the vector in three-dimensional space.

Let's consider an example to illustrate the calculation.

Suppose we have a vector V = (3, -2, 4). We can find the magnitude as follows:

|V| = sqrt(3^2 + (-2)^2 + 4^2)

   = sqrt(9 + 4 + 16)

   = sqrt(29)

   ≈ 5.385

We know that \(\displaystyle{a^0 = 1}\) where a ≠ 0. Therefore,

\(\displaystyle{4^x - 1 - 255=0}\\\\\displaystyle{4^x - 256=0}\)

Add both sides by 256, so we have:

\(\displaystyle{4^x=256}\)

Factor 256 out:

256 = 2 x 128 = 2 x 2 x 2⁶ = 2⁸

Therefore, 256 = 2⁸.

The answer is option (C), that is, the events of rolling a fair die two times are independent. The events are neither disjoint nor exclusive.

When rolling a fair die two times, one can get any one of the 36 possible outcomes equally likely. Let A be the event of obtaining an even number on the first roll and let B be the event of getting a number greater than 3 on the second roll. Let’s see how the outcomes of A and B are related:

There are three even numbers on the die, i.e. A={2, 4, 6}. There are four numbers greater than 3 on the die, i.e. B={4, 5, 6}. So the intersection of A and B is the set {4, 6}, which is not empty. Thus, the events A and B are not disjoint. So option (A) is incorrect.

There is only one outcome that belongs to both A and B, i.e. the outcome of 6. Since there are 36 equally likely outcomes, the probability of the outcome 6 is 1/36. Now, if we know that the outcome of the first roll is an even number, does it affect the probability of getting a number greater than 3 on the second roll? Clearly not, since A∩B = {4, 6} and P(B|A) = P(A∩B)/P(A) = (2/36)/(18/36) = 1/9 = P(B). So the events A and B are independent. Thus, option (C) is correct. Neither option (A) nor option (C) can be correct, so we can eliminate options (D) and (E).
