Answer: $19
Step-by-step explanation: We know Giana earned $10 for shoveling. We know she makes $2 for every inch of snow on the ground. She shoveled 4.5 inches.
To find how much money she got from shoveling 4.5 inches, simply multiply $2 by 4.5
$2.00 x 4.5 = $9 from shoveling 4.5 inches of snow.
Now add $9 to the initial value of $10
$10 + $9 = $19 earned in total.
<u><em>Answer:</em></u>
PART A: Her house: (-4, 9) Her school: (-4, 3). -4 is the same, so we don't need that. |9|=9, |3|=3, and 9 – 3 = 6. So, that means the distance in units from Maria's house to her school is 6 units apart from each other.
PART B: Working on it- I'm sorry if you dislike this-
Answer:
Slope = 1
Step-by-step explanation:
The formula for slope is m= (y2-y1)/(x2-x1)
We have two sets of points
(0,4) , (-2,2)
(x1, y1) , (x2y2)
Now just plug it in equation, m = -2-0/2-4 = -2/-2 = 1
An expression is defined as a set of numbers, variables, and mathematical operations. The derivative of the function f(x)=20(√x)-(x²⁰/2) is (10/√x)-10x¹⁹.
