Jason designed an arch made of wrought iron for the top of a mall entrance. The 11 segments between the two concentric circles a
masha68 [24]
Diameter of the bigger semi-circle is 15 m
circumference of the bigger semi-circle = πd = 15π

diameter of the smaller semi-circle = 15 - 2(1.25) = 15 - 2.5 = 12.5 m
circumference of the smaller semi-circle = πd = 12.5π m

Total length of the segments between the two circles = 11(1.25) = 13.75 m

Total length of wrought iron used = 15π + 12.5π + 13.75 = 100 m

What Values of X will make x2 (Exponent of 2) =16 true? HELPPPPPP!!
Lynna [10]

Answer:

A

Step-by-step explanation:

Given

x² = 16 ( take the square root of both sides )

\sqrt{x^2} = ± \sqrt{16} ← note plus or minus sign

x = ± 4

Since 4² = 4 × 4 = 16 and

(- 4)² = - 4 × - 4 = 16

What are the coordinates of the vertex of the graph of y = x2 + 8x + 1?
Rus_ich [418]

Answer:

y= x2 + 8x - 1 is y=(x+4) 2-17

Step-by-step explanation:

First find  - b/2 = - 4, so  -4 will be added to x inside the parenthesis.

Next , find c - b2 to find the value you added at the end

y= (x- b2) 2 + c - b2

y= (x+4) 2 - 17

A rocket travels in a trajectory given by the equation s = -4.9t 2 + v0t, where s is meters above ground, t is time in seconds a
Reptile [31]

Step-by-step explanation:

s = -4.9t² + 49t

The vertex of the parabola is at t = -b/(2a).

t = -49 / (2 × -4.9)

t = 5

The rocket reaches its maximum height after 5 seconds.
