350 hm/h is 217.48 Miles an hour
Answer:
f(-5) = 0
Step-by-step explanation:
Step 1: Define
f(x) = -2x² - 10x
f(-5) is x = -5
Step 2: Substitute and Evaluate
f(-5) = -2(-5)² - 10(-5)
f(-5) = -2(25) + 50
f(-5) = -50 + 50
f(-5) = 0
Answer:
Step-by-step explanation:
Slope of line A = 
= 
= 3
Slope of line B = 
= 
Slope of line C = 
= 
5). Slope of the hypotenuse of the right triangle = 
= 
= 
Since slopes of line C and the hypotenuse are same, right triangle may lie on line C.
6). Slope of the hypotenuse = 
= 3
Therefore, this triangle may lie on the line A.
7). Slope of hypotenuse = 
= 
Given triangle may lie on the line C.
8). Slope of hypotenuse = 
= 
Given triangle may lie on the line B.
9). Slope of hypotenuse = 
= 
Given triangle may lie on the line B.
10). Slope of hypotenuse = 
= 3
Given triangle may lie on the line A.
Answer:
Step-by-step explanation:
Emma is making two different kinds of cookies for a cookie party she will be attending. She needs 2 and 2/3 cups of sugar for the first recipe and 1 and 1/4 cups of sugar for the second recipe. Emma thinks she will have enough sugar but she isn't quite sure. She knows that her full 2 pound bag of sugar says it contains 4 and 1/2 cups of sugar. Determine the exact difference between the amount of sugar Emma has and the amount of sugar she needs for the recipes.) Emma's mom brought home another 2 pound bag of sugar (4 and 1/2 cups) and wants to make fudge to take to work. Her mom will need 2 and 1/6 cups of sugar. Write a numerical expression that could be used to determine exactly how much sugar will be left over from the two bags of sugar after Emma bakes cookies and her mom makes fudge
