Answer:
no
Step-by-step explanation:
no because its equal to 2x+10
General Idea:
If we have a quadratic function of the form f(x)=ax^{2} +bx+c , then the function will attain its maximum value only if a < 0 & its maximum value will be at x=-\frac{b}{2a} .
Applying the concept:
The height h is modeled by h = −16t^2 + vt + c, where v is the initial velocity, and c is the beginning height of the firecracker above the ground. The firecracker is placed on the roof of a building of height 15 feet and is fired at an initial velocity of 100 feet per second. Substituting 15 for c and 100 for v, we get the function as
.
Comparing the function f(x)=ax^{2} +bx+c with the given function
, we get
,
and
.
The maximum height of the soccer ball will occur at t=\frac{-b}{2a}=\frac{-100}{2(-16)} = \frac{-100}{-32}=3.125 seconds
The maximum height is found by substituting
in the function as below:

Conclusion:
<u>Yes !</u> The firecracker reaches a height of 100 feet before it bursts.
Answer:
76 Square Feet
Step-by-step explanation:
First, add all the numbers you see up. Your final answer of square feet will be the total you added up as a whole.
24+14+4+6+5+3+15+5= 76
Answer:
D. 157°
Step-by-step explanation:
∠EFB and ∠AFB form a linear pair, so are supplementary.
∠EFB = 180° - ∠AFB = 180° -23°
∠EFB = 157°
39. because its close to it lol.
