40e^.06t. What is the average rate of change of f over the
interval [0,3]? Give your answer as a decimal with one place of
accuracy to the right of the decimal point.

Answers

Answer 1

Answer:

[tex]R= 2.6[/tex]

Step-by-step explanation:

Given

[tex]f(x) = 40e^{.06t[/tex]

[tex][a,b] = [0,3][/tex]

Required

Determine the average rate of change (R)

This is calculated as follows:

[tex]R = \frac{f(b) - f(a)}{b - a}[/tex]

Where

[tex]a = 0[/tex] and [tex]b = 3[/tex]

Substitute 0 for a and 3 for b

[tex]R = \frac{f(3) - f(0)}{3 - 0}[/tex]

[tex]R = \frac{f(3) - f(0)}{3}[/tex]

[tex]R = \frac{1}{3}[f(3) - f(0)][/tex]

Calculate f(3)

[tex]f(x) = 40e^{.06t[/tex]

[tex]f(3) = 40e^{.06*3}[/tex]

[tex]f(3) = 40e^{0.18}[/tex]

[tex]f(3) = 40 * 1.197[/tex]

[tex]f(3) = 47.88[/tex]

Calculate f(0)

[tex]f(x) = 40e^{.06t[/tex]

[tex]f(0) = 40e^{.06*0}[/tex]

[tex]f(0) = 40e^{0}[/tex]

[tex]f(0) = 40*1[/tex]

[tex]f(0) = 40[/tex]

So, the expression:

[tex]R = \frac{1}{3}[f(3) - f(0)][/tex]

[tex]R= \frac{1}{3}[47.88 - 40][/tex]

[tex]R= \frac{1}{3}[7.88][/tex]

[tex]R= 2.62666666667[/tex]

[tex]R= 2.6[/tex]

Hence, the average rate of change is approximately 2.6

Answers

Answer:

The equation in point-slope form is:

[tex]y-\left(-8\right)=16\left(x-8\right)[/tex]

The equation of the line in slope-intercept form is:

[tex]y=16x-136[/tex]

Step-by-step explanation:

Given the points

(8, -8)

(9, 8)

Finding the slope between (8, -8) and (9, 8)

[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\left(x_1,\:y_1\right)=\left(8,\:-8\right),\:\left(x_2,\:y_2\right)=\left(9,\:8\right)[/tex]

[tex]m=\frac{8-\left(-8\right)}{9-8}[/tex]

[tex]m=16[/tex]

Point slope form:

[tex]y-y_1=m\left(x-x_1\right)[/tex]

Here:

m is the slope  and (x₁, y₁) is the point

substituting the values m = 16 and the point (8, -8)  in the point-slope form

[tex]y-y_1=m\left(x-x_1\right)[/tex]

[tex]y-\left(-8\right)=16\left(x-8\right)[/tex]

Thus, the equation in point-slope form is:

[tex]y-\left(-8\right)=16\left(x-8\right)[/tex]

now completing the point-slope form equation of the line

[tex]y+8=16\left(x-8\right)[/tex]

subtract 8 from both sides

[tex]y+8-8=16\left(x-8\right)-8[/tex]

[tex]y=16x-136[/tex]

Thus, the equation of the line in slope-intercept form is:

[tex]y=16x-136[/tex]

Answer:

-1 1/8, -3/4, -1/2, 3/8

Step-by-step explanation:

convert to improper fractions and same denominator

-1 1/8 = -9/8

-3/4 = -6/8

-1/2 = -4/8

3/8 = 3/8

Because -1 1/8 is further left on the number line, then -3/4, then -1/2, and finally 3/8.

A square shaped pasture has an area of 144 square feet. What is the perimeter of the pasture?

Answers

Answer:

48 ft.

Step-by-step explanation:

sqr root 144= 12

12x4=48

the perimeter of the square should be 48 square feet.

we know that in a square, all the sides are the same length. the square root of 144 is 12, and we know the square root of a number (12) is what gives the square root (144) when multiplied by itself. the formula of area (in a square) is A = bh, where the b stands for base and the h stands for height. if the base and height multiplied equals 144, we know both the base and height are 12 square feet. so now that we know all of the sides are 12 square feet, we can finally solve perimeter. you find perimeter by adding up all the sides. 12 + 12 + 12 + 12 = 48. (you can also do 12 x 4). this is how we know the perimeter is 48 square feet.

Two artillery bases are located at the points A and C represented in the figure. Each of the bases locates an enemy airplane at point B. The base at A measures the angles of elevation to the airplane to be 95∘ and the distance between the two bases is 739 meters. If the distance from the base at C to the plane is 2,517 meters, what is the measure, in degrees, of ∠CBA?

Answers

Answer:

the answer is 17 here is the step below

Step-by-step explanation:

Use the Law of Sines to find the distance. For a triangle with angles A, B, and C, and opposite sides a, b, and c, the Law of Sines states that sinAa=sinBb=sinCc.

In this case, the angle at point B, let it be α, needs to be found. The Law of Sines can be used to relate α, the two known sides, and the angle at point A.

The Law of Sines states that sinα739=sin95∘2517.

By simplifying, sinα=739sin95∘2517. Since α is acute, α=sin−1(739sin95∘2517)≈17.0∘.

The measure of the angle is 17 degrees if the A measures the angle of elevation to the airplane to be 95∘ and the distance between the two bases is 739 meters.

What is the triangle?

In terms of geometry, the triangle is a three-sided polygon with three edges and three vertices. The triangle's interior angles add up to 180°.

We have a triangle shown in the picture

To find the measure of the angle ∠CBA

Applying sin law:

sin95/2517 = sin∠CBA/739

0.292 = sin∠CBA

∠CBA = sin⁻¹(0.292)

∠CBA = 17 degrees

Thus, the measure of the angle is 17 degrees if the A measures the angles of elevation to the airplane to be 95∘ and the distance between the two bases is 739 meters.
