Answer:
f(3) = 4
Step-by-step explanation:
Give x = 3 in the interval x ≥ 1 then f(x) = x + 1 , and
f(3) = 3 + 1 = 4
Answer:
The height of the stone at the time it is thrown is 15.
Step-by-step explanation:
You have a quadratic function of the form h (x) = ax² + bx + c. In this case it is h (x) = -5x²+10x+15, where a =-5, b =10, c =15, x is the time and h (x) is the height of the stone after being thrown.
The moment the stone is thrown is instant zero. So if x = 0, h (0) is calculated:
h(0)= -5*0² +10*0 +15
h(0)= 0 + 0 + 15
h(0)= 15
The height of the stone at the time it is thrown is 15.
Answer:
60
Step-by-step explanation:
Since the perimeters are equal then:
(3x + 3) * 4 = (x + 8) * 5
12x + 12 = 5x + 40
7x = 28
x =4
Perimeter of square = (3*4 + 3) * 4 =
(12 + 3) * 4 = 60
Perimeter of pentagon = (4 + 8) * 5 =
(12) * 5 = 60
The answer is 60
