Answer:
42.25 feet
Step-by-step explanation:
The height function is a parabola. The maximum value of a negative parabola is at the vertex, which can be found with:
x = -b/2a
where a and b are the coefficients in y = ax² + bx + c.
Here, we have y = -16t² + 52t. So a = -16 and b = 52. The vertex is at:
t = -52 / (2×-16)
t = 13/8
Evaluating the function:
h(13/8) = -16(13/8)² + 52(13/8)
h(13/8) = -169/4 + 169/2
h(13/8) = 169/4
h(13/8) = 42.25
Answer: 2929 π inch
Step-by-step explanation:
Circumference is given by= 2πr
Here r= 1010 inches
So Tip of minute hand moves= 2π (1010inch)
= 2020 π inch for an hour
Now it comes from 12 to 33 o'clock= 1.45 hour so,
Tip of minute hand moves= 2020 π inch x 1.45
Tip of minute hand moves= 2929 π inch
56,900 but I'm only 50% sure I don't know about the other 50% sorry If its wrong.
A^2 + B^2 = C^2
6^2 + B^2 = 7^2
36 + B^2 = 49
B^2 = 13
B = 3.61

Step-by-step explanation:
Remember PEMDAS???
"parenthesis, exponents, multiplication, division, addition, subtraction"
you would first solve the addition inside of the parentheses (1 + 2 = 3), and from there finish the equation as it's written from left to right.
