F(10)= -(10)^2-9(10)-4=-194
Answer:
Distance between points (5, -3) and (0, 2) is √50 or 7.07
Step-by-step explanation:
We need to find distance between two points (5,-3) and (0,2)
The distance formula used is:

here
x₁= 5, y₁=-3, x₂=0 and y₂=2
Putting values in the formula:

So, distance between points (5, -3) and (0, 2) is √50 or 7.07
Answer: 8/7
Step-by-step explanation:
Answer:
Step-by-step explanation:
a. the balloon is rising because the slope is positive. the slope is 40 because when you simplify y-160 = 40 (x-1) it gets you y = 40x +120
b. it is ascending (bc positive) at 40 feet per minute
c. it was at 120 feet in the air. The 120 is the y intercept
