A. The statement Amy's account will earn $246.75 in interest is True

B. The statement Amy's account will be worth $2,753.25 after 3.5 years

is False

C. Amy's account would earn $15.75 more in interest if the annual

interest rate were raised to 2.5% is True

Step-by-step explanation:

Simple interest rule is I = Prt , where I is the interest, p is the money

invested, r is the annual rate in decimal and t is the time

The given is:

1. The money invested is $3,000

2. The simple annual interest is 2.35%

3. The time is 3.5 years

∵ P = 3000

∵ r = 2.35 ÷ 100 = 0.0235

∵ t = 3.5

- Substitute these values in the rule above to find the interest

∴ I = 3000(0.0235)(3.5)

∴ I = 246.75

A. Amy's account will earn $246.75 in interest ⇒ True

To find the total money that Amy has after 3.5 years add the money

invested to the interest

∵ Total money = P + I

∵ P = 3000 and I = 246.75

∴ Total money = 3000 + 246.75

∴ Total money = 3246.75 dollars

B. Amy's account will be worth $2,753.25 after 3.5 years ⇒ False

∵ P = 3000

∵ r = 2.5 ÷ 100 = 0.025

∵ t = 3.5

- Substitute these values in the rule above to find the interest

∴ I = 3000(0.025)(3.5)

∴ I = 262.5

∵ I of 2.35% = 246.75

∴ The difference = 262.5 - 246.75 = 15.75

C. Amy's account would earn $15.75 more in interest if the annual

interest rate were raised to 2.5% ⇒ True

Which pair of points have a slope of -3/5?
Allushta [10]

Answer:

No of these answers has a slope of  \frac{-3}{5} . My guess is B becasue its close to \frac{-3}{5} unless the 5 is supposed to be negative

Step-by-step explanation:

You have to use the slope formula \frac{y_{2} - y_{1} }{x_{2} - x_{1} }

(x_{1},y_{1}), (x_{2},y_{2})

(4, 0), (-2, 10)   \frac{10 - 0 }{-2 - 4 }= \frac{10}{6} you have to simplfy, the answer will be \frac{5}{3}

(10, -2), (0, 4)  \frac{4 - -2 }{0- 10 }= \frac{6}{-10} you have to simplfy, the answer will be \frac{3}{-5}

 (4, 2), (10, 4)  \frac{4 - 2 }{10 - 4 }= \frac{2}{6} you have to simplfy, the answer will be \frac{1}{3}

 (-4, -10),(0, -2) \frac{{-2- -10} }{0 - -4 }= \frac{8}{4} you have to simplfy, the answer will be \frac{2}{1} =2

The length of a rectangle is increasing at a rate of 6 cm/s and its width is increasing at a rate of 5 cm/s. When
atroni [7]

Answer:

The area of the rectangle is increasing at a rate of 84 square centimeters per second.

Step-by-step explanation:

The area for a rectangle is given by the formula:

A=w\ell

Where <em>w</em> is the width and <em>l</em> is the length.

We are given that the length of the rectangle is increasing at a rate of 6 cm/s and that the width is increasing at a rate of 5 cm/s. In other words, dl/dt = 6 and dw/dt = 5.

First, differentiate the equation with respect to <em>t</em>, where <em>w</em> and <em>l</em> are both functions of <em>t: </em>

\displaystyle \frac{dA}{dt}=\frac{d}{dt}\left[w\ell]

By the Product Rule:

\displaystyle \frac{dA}{dt}=\frac{dw}{dt}\ell +\frac{d\ell}{dt}w

Since we know that dl/dt = 6 and that dw/dt = 5:

\displaystyle \frac{dA}{dt}=5\ell + 6w

We want to find the rate at which the area is increasing when the length is 12 cm and the width is 4 cm. Substitute:

\displaystyle \frac{dA}{dt}=5(12)+6(4)=84\text{ cm}^2\text{/s}

The area of the rectangle is increasing at a rate of 84 square centimeters per second.
