The quadratic function h(t) = −4.9t^2 + 50t + 2 represents the height, in meters, of a toy rocket t seconds after launch. How many seconds will it take the toy to reach the ground? State your answer to the nearest whole second.
Answers
Answer:
The toy reaches the ground in 10 sec
Step-by-step explanation:
When the rocket hits the ground, h becomes zero (0). Thus, our problem here is to solve the equation h(t) = −4.9t^2 + 50t + 2 = 0,
Because of the fractional coefficient -4.9, it's best to use the quadratic equation here. The coefficients of the t terms are {-4.9, 50, 2}. Thus,
the discriminant is b^2 - 4ac = 50² - 4(-4.9)(2) = 2539.2, and the square root of this is 50.39.
The quadratic formula is as follows:
-b ± √discriminant
t = -------------------------------
2a
which here is:
-50 ± 50.39
t = ------------------------ Since t represents time, only the positive result
-9.8 is relevant here; it is 10.24 sec,
which rounds off to 10 sec

14/9x X 9x= -42 X 9x
14= -378x
-378x= 14

Which equation represents a linear function?
A. y= 1/2 x to the second power - 5
B. y= 1/2 x to the third power - 5
C. y= 1/2 x + 5
D. y=(1/2) to a power - 5
Answers
Answer:
C. y = 1/2x + 5
Step-by-step explanation:
For A. and B. x to a power of something, if x is at a power of anything, like x^2 or x^3, then it is not linear.
For D. it doesn't even have x in it, so basically y equals a number.
C. is a linear equation, y = 1/2x + 5
This is because any slope to a certain power would make it an exponential function.
C. y= 1/2 x + 5 is not to any power, making it linear

[Help Please!] Find the value of x.
Answers
Answer:
x = 52
Step-by-step explanation:
The exterior angle is equal to the sum of the opposite interior angles of a triangle
x+72 = 34+90
x +72 =124
Subtract 72 from each side
x = 124-72
x =52
Answer:
x = 52 degrees
Step-by-step explanation:
Let's first focus on the angle x + 72. Immediately adjacent to x + 72 is angle RQS. These two angles are "straight" in that they lie immediately adjacent to one another and add up to 180 degrees. Then angle RQS can be expressed as
180 degrees - (x + 72 degrees), or 108 - x degrees.
The three interior angles of the triangle must add up to 180 degrees. Hence
108 - x degrees + 34 degrees + 90 degrees = 180 degrees, and so:
108 - x + 34 = 90
This yields x = 52 degrees.

First find the area of the entire figure.
L= 36
W = 20
Area = 36 * 20 = 720
Find the area of the left right triangle.
Height = 20
Base = 1/2 * 36 = 18
Just as an aside, let me be a little grumpy for a moment. You should never have to guess what a dimension is on a diagram. It's sloppy. However for this problem you have no choice. But you could think to complain to your teacher.
Area = 1/2 * base * height
Area = 1/2 * 18 * 20 = 180
Find the area of the bottom right triangle.
The height is 1/2 20 = 10
The base is 36
Area of the lower triangle = 1/2 * 36 * 10 = 180
Area of the shaded figure = 720 - 180 - 180 = 360
