Answer:
Step-by-step explanation:
The coefficient of Y is 6
Answer: y = -90, 90
Step-by-step explanation:
To solve this, we will isolate the variable.
Given:
10 = ||
Absolute value:
10 = & -10 =
Multiply both sides of both equations by 9:
90 = y & -90 = y
Answer:
y = -90, 90
-4x + 2y = 24
X-Intercept: -4x + 2y = 24
-4x + 2(0) = 24
-4x + 0 = 24
-4x = 24
-4 -4
x = -6
Y-Intercept: -4x + 2y = 24
-4(0) + 2y = 24
0 + 2y = 24
2y = 24
2 2
y = 12
The answer is A.
Answer:
The correct answer is 8 feet.
Step-by-step explanation:
Height of the dirt bike is given by the equation h = 16 + 20 t +8.
Initial velocity of the dirt bike is 20 feet per second
Initial height of the dirt bike when it launches off the ramp is 8 feet.
To find the maximum h, we differentiate the function h with respect to t and equate the result to zero.
⇒ h = 0 = 32t + 20
and second order differentiation of h gives = 32.
This gives the value of the function maximum at t = -0.625 seconds.
This is absurd as the value of t cannot be negative.
Thus the dirt bike is going to fall off the ramp and is not going to gain any height, making the height at t = 0 the maximum height attained by it.
