What is the perimeter P of △DEF to the nearest whole number?

A triangle DEF. The length of DF is 10. The base angle E is 49 degrees and F is 42 degrees.

The point \((- \ln(3)/2, y(- \ln(3)/2))\) is an inflection point where the concavity changes from up to down.

To determine the concavity and inflection points of the function \(y = e^{-t} - e^{-3t}\), we need to analyze its second derivative. Let's find the first and second derivatives of \(y\) with respect to \(t\):

\(y' = -e^{-t} + 3e^{-3t}\)

\(y'' = e^{-t} - 9e^{-3t}\)

To determine concavity, we examine the sign of the second derivative. When \(y'' > 0\), the function is concave up, and when \(y'' < 0\), it is concave down.

Setting \(y''\) to zero, we solve \(e^{-t} - 9e^{-3t} = 0\) for \(t\), which gives \(t = -\ln(3)/2\).

Considering the intervals \(-\infty < t < -\ln(3)/2\) and \(-\ln(3)/2 < t < \infty\), we can analyze the signs of \(y''\).

For \(t < -\ln(3)/2\), \(y''\) is positive, indicating a concave up portion. For \(t > -\ln(3)/2\), \(y''\) is negative, indicating a concave down portion.

Hence, the point \((- \ln(3)/2, y(- \ln(3)/2))\) is an inflection point where the concavity changes from up to down.

About $6,000 more compound interest than simple interest is earned after 35 years, and about $12,500 more compound interest than simple interest is earned after 45 years.

What is a graph ?

A graph is a visual representation of data that shows the relationship between two or more variables. It is a way of presenting information in a clear and concise manner that makes it easy to interpret and understand.

Graphs can be used to show trends over time, compare different groups or categories, or illustrate the relationship between two or more variables.

Since the graph shows the balance for two accounts with the same principal and annual interest rate, we can assume that one account is earning simple interest while the other is earning compound interest.

To estimate the amount of compound interest earned after 35 years, we can look at the difference in balance between the two accounts at that time. From the graph, we can see that the balance for the simple interest account after 35 years is approximately $4,000, while the balance for the compound interest account is approximately $10,000. Therefore, the amount of compound interest earned after 35 years is approximately:

$10,000 - $4,000 = $6,000

To estimate the amount of compound interest earned after 45 years, we can again look at the difference in balance between the two accounts at that time. From the graph, we can see that the balance for the simple interest account after 45 years is approximately $5,500, while the balance for the compound interest account is approximately $18,000. Therefore, the amount of compound interest earned after 45 years is approximately:

$18,000 - $5,500 = $12,500

Therefore,  about $6,000 more compound interest than simple interest is earned after 35 years, and about $12,500 more compound interest than simple interest is earned after 45 years.

ΔXYZ will also be an equilateral triangle.

What is equilateral triangle?

An equilateral triangle in geometry is a triangle with equal-length sides on all three sides. In the well-known Euclidean space, an equilateral triangle also is equiangular, meaning that each of its three internal angles is 60 degrees and congruent with the others. It's also referred to it as a regular triangle because it is a regular polygon.

As X,Y,Z are the midpoints of sides of equilateral triangle so when we will join the X,Y,Z we will find that distances XY=YZ=XZ are three are equal because this is proved by similarity of triangles which in itself is a detailed and vast topic

The length of the arc is approximately 7.85 units.

The length of an arc is a portion of the circumference of a circle, defined by the central angle that intercepts the arc. The length of the arc is proportional to the angle it subtends and the radius of the circle. The larger the angle, the longer the arc, and the larger the radius, the longer the arc.

The formula for the length of an arc is:

Length of Arc = (angle/360) × 2πr

where angle is the central angle in degrees that intercepts the arc, and r is the radius of the circle.

To find the length of an arc, you need to know the measure of the central angle (in degrees) and the radius of the circle. If you have this information, you can substitute it into the formula and solve for the length of the arc.

For example, suppose we have a circle with a radius of 10 units, and we want to find the length of the arc that subtends a central angle of 45 degrees. Using the formula, we get:

Length of Arc = (45/360) × 2π(10)

= (1/8) × 20π

= 5π/2

≈ 7.85 units

Therefore, the length of the arc is approximately 7.85 units.

A player would need to make a goal in less than 6.78 minutes to be sponsored by the puck company.

This is because 10% of goals are made in less than one standard deviation below the mean, which is 12.56 - (8.73 * 0.67) = 6.78 minutes. This is assuming that the distribution of goal times follows a normal distribution, which is a common assumption for many real-world data sets.

The standard deviation is a measure of how spread out the data is, and by multiplying it by 0.67, we can find the point that represents the 10th percentile of the data. In this case, the 10th percentile of goal times is less than 6.78 minutes, meaning that the top 10% of goal times fall below this threshold.

The order of the given reaction is first and the rate constant of the given reaction is 0.346 M⁻¹ s⁻¹.

To determine the order of the reaction, we need to examine the relationship between the concentration of the reactant and the reaction rate. One way to do this is to plot the natural logarithm of the concentration versus time and observe the slope of the resulting line.

From the given data, we can construct the following table

[A](M)            ln[A]               1/[A]

0.00                 -                    -

20.0               -0.693           0.050

40.0               -0.944           0.025

60.0               -1.19               0.017

80.0               -1.44              0.013

100.0             -1.69              0.010

Plotting ln[A] versus time yields a straight line, indicating that the reaction is first order with respect to [A].

To determine the rate constant (k), we can use the first-order integrated rate law

ln([A]t/[A]0) = -kt

where [A]t is the concentration of A at time t, [A]0 is the initial concentration of A, and k is the rate constant.

From the table, we can see that when [A] = 20.0 M, ln([A]t/[A]0) = -0.693. Plugging in the values and solving for k gives

k = -ln([A]t/[A]0)/t

k = -(-0.693)/(2.002)

k = 0.346 M⁻¹ s⁻¹

Therefore, the value of the rate constant for this reaction is 0.346 M⁻¹ s⁻¹.

Answer:

2 solutions

Step-by-step explanation:

Given the 2 equations

y = x² + 4x + 4 → (1)

y = 2x + 7 → (2)

Substitute y = x² + 4x + 4 into (2)

x² + 4x + 4 = 2x + 7 ( subtract 2x + 7 from both sides )

x² + 2x - 3 = 0 ← in standard form

(x + 3)(x - 1) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 3 = 0 ⇒ x = - 3

x - 1 = 0 ⇒ x = 1

Substitute these values into (2) for corresponding values of y

x = - 3 : y = 2(- 3) + 7 = - 6 + 7 = 1 ⇒ (- 3, 1 )

x = 1 : y = 2(1) + 7 = 2 + 7 = 9 ⇒ (1, 9 )

Step-by-step explanation:

Let x be the total amount divided

Karen gets (2/7) x

Natasha gets  (5/7) x

(5/7) x  = (2/7) x + 210

Multiply both sides by 7

5x = 2x + 1470

3x = 1470

x = 490

Natasha gets (5/7) (490) = 350

Karen gets (2/7)(490) = 140

The difference in ration is 5 - 3 = 2. So divide 150 by 2 to get the amount for each part of the ratio which is 75. the total ration is 3 + 5 = 8. So to get the total original sum of money, multiply 75 and 8 which is $600. for each person just multiply 75 with their respective ratios. For A: 75 X 3 = $225. For B: 75 x 5= $375.

the measure of the exterior angle ECD is 140 degrees.

Answer:

110°

Step-by-step explanation:

The sum of the angles in a triangle is equal to 180°

So, 2x°+3x°+(3x+4)°=180°

8x°+4°=180°

8x°=180°- 4°

8x°=176°

x°=22°

The exterior angle theorem states that when a triangle's side is extended, the resultant exterior angle formed is equal to the sum of the measures of the two opposite interior angles of the triangle.

So, the exterior angle is 2x°+3x°=5x°

As we got x°=22°, then 5x°=5×22°=110°

The expression for the length of the sail is x = 7( tan 50° ).

According to the given question.

The sail of a boat is in the shape of a right triangle.

And, the sail of a boat is a right triangle with an acute angle at the tip equal to 50 degrees and the side of the sail which is the hypotenuse to the right triangle is 7 meters long.

Now, the side that measures 7 meters would be the adjacent because its right next to the angle and its not the hypotenuse because its not the largest side

And, the side which we do not know the length to will be the opposite side because it is opposite from where the angle is.  

So, we have the the measure of the adjacent side and the angle of the tip. And we have to find the expression for the length of the sail.

Let the length of the sail be x meters.

Now, in the given right angled triangle

We can say that

tan A = Opposite side/Adjacent side

⇒ tan 50° = x/7

⇒ x = 7( tan 50° )

Hence, the expression for the length of the sail is x = 7( tan 50° ).

The piecewise-defined functions f(x) = -x + 2 and g(x) = x + 2 have the same rule for x greater than 0, but different rules for x less than or equal to 0. Specifically, f(x) is equal to -x + 2 for x less than 0, while g(x) is equal to x + 2 for x less than 0. This means that the graph of f(x) will be a line with slope -1 that passes through the point (2, 0) in the negative x-axis quadrant, while the graph of g(x) will be a line with slope 1 that passes through the point (2, 0) in the negative x-axis quadrant.

On the other hand, the functions x^2 + 1 and x^2 + 2 have different rules for all values of x, but the same degree and leading coefficient. Specifically, x^2 + 1 has a constant term of 1, while x^2 + 2 has a constant term of 2.

The total amount of monthly payments = Monthly payments × Number of months

                                                                  = 48.5 × 30

                                                                  = 1447.50

The total cost = Total amount of monthly payments + Down payments

                       = 1447.50 + 150

                       = 1597.50
