Answer:
x = -5 , y = -5
Step-by-step explanation:
- 8y + 9x = -5
8y + 7x = -75
__________
0 + 16x = - 80
x = -80 / 16
x = -5
- 8y + 9x = -5
-8y + 9(-5) = -5
-8y - 45 = -5
-8y = -5 + 45
-8y = 40
y = 40/-8
y = -5
hope it helps!
Answer:
The object will hit the ground after 10.308 seconds.
Step-by-step explanation:
h(t) = -16t² + 1700
If you graphed this function, the object would be shown hitting the ground when it crosses the x-axis, in other words, when h = 0. So, to find the answer, just set h(t) equal to 0 and solve.
-16t² + 1700 = 0 Plug this into a calculator if you have one.
t = -10.308 and t = 10.308
Since time can't be negative, your answer will be the positive value, 10.308.
Lateral Area of a cylinder is ; 2πR.H
R=12 mm and H= 15 mm
Then LATERAL area = 2π(12)(15) =48π ≈ 150 mm²
Answer:
slope = -6 and y intercept=0
Step-by-step explanation:
Parallel to the x-axis and perpendicular to the y-axis: zero
Parallel to the y-axis and perpendicular to the x-axis: undefined
I hope that's right, that's how I remember it
