Step-by-step explanation: In its easiest form, an A=4, B=3, C=2, D=1, F=0.

If the class is 2 credit.......Multiply each numeric grade value by the number of credits the course was worth

Add these numbers together

Divide 45 by the total number of credits you took, in this example,13.

Your Weighted by Credit Hour GPA = 3.46

It depends on your school. Sorry this was not the most clear, I was taught like 2 years ago, and now I kinda forgot but hopefully this helps a lil dont get mad :)

The dimension of the rectangle is,

The length of the rectangle is 7 feet.

And the width of the rectangle is 8 feet.

Given that,

If the width of a rectangle is 9 ft less than twice its length and the perimeter is 30 feet,

We have to determine,

What are the dimensions of the rectangle?

According to the question,

Let, the width of the rectangle is W,

And the length of a rectangle is L = 2W - 9,

The perimeter of the rectangle is = 2(L+W)

Where perimeter is 30 feet,

Therefore,

[tex]30 = 2(2W-9+W)\\\\30 = 2(3W-9)\\\\30 = 6W-18\\\\30 + 18 = 12W\\\\48 = 6W\\\\W = \dfrac{48}{6}\\\\W = 8 \ feet[/tex]

And the length of a rectangle is,

[tex]L = 2W - 9, \\\\L= 2(8) - 9\\\\L = 16-9 \\\\L =7 \ feet.[/tex]

Hence, The dimension of the rectangle is, the length of the rectangle is 7 feet, and the width of the rectangle is 8 feet.

Answer:

C

Step-by-step explanation:

Listen, just think about it.

If 5 times “x” is subtracted from 27 (so 27-5x) if the result/answer

(meaning its equal “=“ ) is 9+ than 4 times “x” (soo basically like 4x +9). If you put all of those 2 equations together you get 27 x 5x = 4x + 9.

(I use “x” to as the variable and remember when a variable is next to a number it means you have to multiply whatever that number is)

Hi there!

[tex]\large\boxed{-40 + 20i}[/tex]

Recall the rules for the imaginary number "i":

i = √-1          i² = -1

Given:

(5i) (5i) + (5i) (4 + 3i)

Multiply:

(25i²) + 20i + 15i²

Simplify using the rule above:

25(-1) + 20i + 15(-1)

-25 + 20i - 15

-40 + 20i

a = -40

b = 20

Answer:

-2

Step-by-step explanation:

first, you want to graph your points on a graph. A really good online graphing calculator i like is called desmos.

next, slope is rise over run. count how many units up or down from leftmost point to the other. in this case it is -8.

third, find the run part of the slope by counting units right or left from the leftmost point to the other. in this case it is 4.

last, but the two numbers together in a fraction and simplify. rise over run.

-8/4 which simplifies to -2/1 which is the same thing as -2

Pi is an infinite decimal.

We need to find time taken to reach arrow to its maximum.

The path of the arrow can be modeled with the equation [tex]y=-x^2+ 42x-80[/tex] .

Differentiating the given equation w.r.t x and equate it to zero.

[tex]\dfrac{dy}{dx}=-2x + 42 \\\\42 - 2x = 0\\\\x = 21\ seconds[/tex]

Putting value of x = 21 sec in given equation, we get :

[tex]y=-x^2+ 42x-80\\\\y = -(21)^2 + (42\times 21) - 80\\\\y = 361 \ feet[/tex]

Therefore, time taken to reach maximum height is 21 seconds.
