Answer:
x = 39
Step-by-step explanation:
The Pythagorean theorem tells you the sum of the squares of the sides of a right triangle is the square of the hypotenuse.
x² +80² = 89²
x² = 89² -80² = 7921 -6400 = 1521
x = √1521
x = 39
Answer:
y = (-3/2x) + (35/4)
Step-by-step explanation:
So the perpendicular line will have a slope that is the opposite reciprocal of the other line's slope. Solve for the original line's slope first:
2x - 3y = 7 --> -3y = -2x + 7 --> y = (2x/3) - (7/3)
So, the slope of the perpendicular line will be (-3/2x)
Solve for the y-intercept of the perpendicular like by using the linear equation and substituting in (2,8):
8 = (-3/(2*2)) + b --> (32/4) = -(3/4) + b --> b = (35/4)
So, y = (-3/2x) + (35/4)
Hope that helps! :D

Answer:
Step-by-step explanation:
I think the missing equation in your question is: h(t) = -16
+ 16t + 480
Here is my answer:
As we know that the vertex form of a parabola, y=a
+ k where(h,k) is the vertex
h(t) = -16
+ 16t + 480
= -16 (
+ 480
= -16
+ 484
So the vertex is (
, 484)
a. It take for Joseph
second to reach his maximum height
b. The highest point that Joseph reached is the vertex of the function, it is 484 ft
c. Joseph hit the water after how many seconds?
<=> h(t) = 0
<=> -16
+ 16t + 480 = 0
<=> t =
second = 6 sec
Hope it will find you well
