Answer:

A) 20 represents the amount of money saved in one month or amount saved per month. This is the slope or rate of change of the function.

B) 50 represents the amount of money already present in the account when she starts saving. This is the y-intercept of the function.

C) It will take 5 weeks for her to save $150

Step-by-step explanation:

A) 20 represents the amount of money saved in one month or amount saved per month. This is the slope or rate of change of the function.

B) 50 represents the amount of money already present in the account when she starts saving. This is the y-intercept of the function.

C) The time to reach $150

150 = 20(w) + 50

20(w) = 150 - 50

20w = 100

w = 100/20

w = 5

It will take 5 weeks

98 pts to correct answer! CALCULUS BC Trig Substitution (SEE Attached)

storchak [24]

Answer:

Step-by-step explanation:

Let x = Tan $(\theta)$

dx = sec² $(\theta)$ d $(\theta)$

sqrt(1 + $Tan^2(\theta)$ ) = sec $(\theta)$

So I = Tan(theta) * sec(theta)

but Tan(theta) = sin(theta) / cos(theta) = sin(theta)*sec(theta)

So I = integral sin(theta)*sec^2(theta) d theta

Write the equation of the line that passes through (5, 6) and (8, 4) in slope-intercept form.

gavmur [86]

Answer:

Step-by-step explanation:

<h3>Equation of the line in slope- intercept form:</h3>

$\sf \boxed{\bf y = mx +b}$

Here, m is the slope and b is the y-intercept

Find the slope with the given two points.

$\sf \boxed{slope = \dfrac{y_2-y_1}{x_2-x_1}}$

$\sf =\dfrac{4-6}{8-5}\\\\=\dfrac{-2}{3}$

Slope = -2/3 and choose any one the given points.

Substitute m = -2/3 and (5,6) in the above equation and find 'b'

$\sf 6 =\dfrac{-2}{3}*5+b\\\\6 =\dfrac{-10}{3}+b\\\\6+\dfrac{10}{3}=b\\\\\dfrac{6*3}{1*3}+\dfrac{10}{3}=b\\\\\dfrac{18}{3}+\dfrac{10}{3}=b\\\\\boxed{b=\dfrac{28}{3}}$

Equation of the line:

$y = \dfrac{-2}{3}x + \dfrac{28}{3}$

joe has a cylindrical glass jar that he wants to fill completly with apple juice. This jar has a diameter of 4 inches and a heig

KonstantinChe [14]

Answer:

V = πr²h

Step-by-step explanation:

The formula for the volume of a cylinder is ...

V = πr²h

where V is the volume, r is the radius, and h is the height of the cylinder.

_____

<em>Comment on the formula</em>

This is a specific version of the formula for any sort of "prism" with parallel bases and a uniform cross section (parallel to the bases). The volume of such a figure is computed as ...

V = Bh

where B is the area of the base and h is the perpendicular distance between the parallel bases. Here, the base is a circle, so has area formula ...

B = πr²

Filling this into the volume formula gives ...

V = πr²h . . . . . as above

Your friend is thinking of two numbers.

frosja888 [35]

Answer:

2) 2x = y + 13

Step-by-step explanation:

We have to translate the given information into an equation. We don't know what the numbers are yet, so let the first number be represented by the variable x and the second number be represented by the variable y.

Start by breaking the sentence apart. "2 times the first number" gives us $2x$ . The "is" in the sentence means that $2x$ equals something, bringing us to $2x =$ . Finally, it says "13 more than the second number." 13 more would mean you have to add to the second number, represented by y, so this gives us $y + 13\\$ . Put it all together and it is $2x = y + 13\\$ .
