Emily plans to put her graduation money into an account and leave it there for 4 years while she goes to college. She receives $750 in graduation money that she puts into an account that earned $127.50 in interest. What was the interest rate that the bank provided

Answer:

r≤0

Step-by-step explanation:

if the range is s≤0, (that means the value of s is all negative integers &0) to find the domain we have to replace that some negative integers &0.

we can replace some values of s as the following

s=‒4(0)^2 s=‒4(‒1)^2

=‒4(0) =‒4(1)

=0 =‒4

s=‒4(‒2)^2 s=‒4(‒3)^2

=‒4(4) =‒4(9)

=‒16 =‒36

so we can understand easly that the domain is negative integer&0,it can't be positive because the square of any integer is positive.

therefore the answer is r≤0

i think &i hope it is clear.

The domain is the set of values for which the given function is defined. The domain of the function s=-4r² if the range is s≤0 is r∈R. The correct option is B.

For the given function s=-4r², the domain of the function when s≤0 will be all the real numbers. This is because, for any value of r whether it is positive or negative, the value of r² will be positive, but at the same time this quantity is needed to be multiplied by -4.

Thus, the result of -4r² will be always negative, which is less than zero.

Hence, the domain of the function s=-4r² if the range is s ≤0 is r∈R.

Answer:

Number of yards per day = 20.83 yard (Approx)

Step-by-step explanation:

Assume;

Number of yards = x per day

Number of yards on 6th day = x + 8

Total yards = 133

Find:

Number of yards per day

Computation:

Total yards = 5[x] + x + 8

133 = 6x + 8

6x = 125

x = 20.83 yard

Number of yards per day = 20.83 yard (Approx)

Answer:

20.83 yards

Step-by-step explanation:

Calculate Cubic Yards

Calculate your area

Calculate your volume: Multiply area times the depth to get volume in cubic feet

Calculate your cubic yards: Divide cubic feet by 27 to convert to cubic yards and this is your answer

Where ft2 = square foot, ft3 = cubic foot, yd3 = cubic yard

Total yards = 5[x] + x + 8  

Solve

133 = 6x + 8

6x = 125

x = 20.83 yard

Therefore, the Cyclone cleared 20.83 yards on the first day.

Answer:

Step-by-step explanation:

3.8/0.2 = 19.0

Answer:

Step-by-step explanation:

Use the slope formula:

[tex]m = \frac{y2 -y1}{x2 - x1}[/tex]

where m = slope

(-5, 0) -> means x1 = -5. y1 = 0

(7, 8) -> means x2 = 7 , y2 = 8

Substitute these values into the slope formula above and you get:

[tex]m = \frac{y2 -y1}{x2 - x1} = \frac{8-0}{7- (-5)} = \frac{8}{7+5} = \frac{8}{12} = \frac{2}{3}[/tex]

The slope of the line that passes through the points (-5,0) and (7,8) is 2/3

The formula for calculating the slope of a line is expressed as:

[tex]m = \frac{y_2-y_1}{x_2-x_1} \\m=\frac{8-0}{7-(-5)} \\m=\frac{8}{7+5}\\m=\frac{8}12} \\m= \frac{2}{3}\\[/tex]

Hence the slope of the line that passes through the points (-5,0) and (7,8) is 2/3

Answer:

d = 4

Step-by-step explanation:

First, we take the equation 2d = 8

In order to find out what the value of 9 must be in order to make this equation true, we must isolate the variable. That can be done by doing the opposite operation. In this case, the opposite operation would be division since d is being multiplied by 2 to get 8.

So, we have to divide both sides of the equation by 2:

2d = 8

2      2

2d divided by 2 is equal to d.

And 8 divided by 2 is equal to 4.

Therefore, d is equal to 4.

Hope this helps!!

Answer:

  E.  40 and 33

Step-by-step explanation:

The Pythagorean theorem tells you the sum of the areas of the smaller squares will match the area of the largest square.

The answer choices have sums of ...

  A: 76; B: 73; C: 96; D: 66; E: 73

So, choices with the correct sum are B and E.

If this question asks you to "choose all that apply," then B & E will be your answer choices.

__

We note that the areas of the smaller squares appear to be not much different in size. If their areas were 23 and 50, the smaller square would be less than half the size of the larger one. So, if the figure is drawn approximately to scale, the choice of 40 and 33 is a better choice.

Answer:

y = -2x

Step-by-step explanation:

The equation of a line in point slope form is

y-y1 = m(x-x1)

Where m is the slope and (x1,y1) is a point on the line

y - 6 = -2(x- -3)

y - 6 = -2(x+3)

Distribute

y-6 = -2x-6

Add 6 to each side

y-6+6 = -2x-6+6

y = -2x

Answer:

Step-by-step explanation:

y - 6 = -2(x + 3)

y - 6 = -2x - 6

y = -2x

Answer:

the y intercept is -4 or (0,4)

Step-by-step explanation:

To find the y intercept you have to make x zero, and vice versa. So:

0-3y = 12

-3y = 12

y = 12/-3

y = -4

the y intercept is -4 or (0,4)

Answer: y = 1.2x + 2

Step-by-step explanation:

slope = (8 - 2)/(5 - 0) = 6/5

y-intercept = (0, 2)

y = (6/5)x + 2

y = 1.2x + 2

So you want to get x by itself.

x3= [tex]\frac{64}{27}[/tex]

You could simplify

x3=2.37037037037

Then just divide 3 on both sides

x=0.79012345679

x= [tex]\frac{21.3}{9}[/tex] or just 2.36666666667.
