An object is launched at 20 m/s from a height of 65 m. The equation for the height (h) in terms of time (t) is given by h(t) = -4.912 + 20t + 65. What is the
object's maximum height?
Answer:
The maximum height is the y-value of the vertex.
h(t) = -4.9t² + 20t + 65
a=-4.9 b=20 c=65
h(2) = -4.9(2)² + 20(2) + 65
= -19.6 + 40 + 65
= 85.4
Step-by-step explanation:
find the measures of one interior angle and one exterior angle of a regular polygon with 8 sides
one interior angle__________ one exterior angle___________
Answer:
one interior angle 135
one exterior angle 45
Step-by-step explanation:
Total measure of all angles in a 8 sided regular polygon = (n - 2)* 180
= ( 8 - 2 ) * 180
= 6 * 180
= 1080
Measurement of one interior angle = 1080 / 8 = 135
Interior angle and exterior angle make linear pair.
Measurement of one exterior angle = 180 - 135 = 45

The perimeter of a rectangle is 85 ft. The length of the rectangle is two (x plus 16) and the width is 3x - 1. What is the length of the rectangle?
Answer:
The length of the rectangle is 27 ft.
Step-by-step explanation:
To determine the length of the rectangle, we will first determine the value of x.
From the question,
The length of the rectangle is 2x + 16
The width is 3x - 1
and the perimeter is 85 ft
From the formula for perimeter of a rectangle which is given by
P = 2(l+w)
Where P is the perimeter
l is the length
and w is the width
Then, we can then write that
85 = 2(2x+16 + 3x - 1)
85 = 2(5x + 15)
85 = 10x + 30
10x = 85 - 30
10x = 55
x = 55/10
x = 5.5 ft
Since the length of the rectangle is 2x+16, substitute the value of x
Therefore
l = 2x + 16
l = 2(5.5) + 16
l = 11 + 16
l = 27 ft
Hence, the length of the rectangle is 27 ft.

Maria played a game with her little sister for 25 hour and read her little sister a book for 58 hour.
What is the best estimate for the total time Maria spent with her little sister?
Drag and drop an answer into each box to correctly complete the sentences.
25 hour is closest to . 58 hour is closest to . Therefore, the best estimate for the total time Maria was with her sister is close to .
Answer:
90
58 is closer to 60 and 25 is closer to 30. So when you add them you get 90.

Suppose the polynomial function f has a zero at x = -3. Which of the following statements must be true?
a) (3,0) is an x-intercept of the graph of f.
b) (0,3) is a y-intercept of the graph of f.
c) x - 3 is a factor of f(x).
d) f(-3) = 0
Answer:
d) f(-3)=0
Step-by-step explanation:
Given that f is equal to zero at x=-3
So, f(-3)=0

You play a where you draw one card from a standard deck of playing cards. If you pick a diamond, you win $10. If you pick a face card, which is not a diamond, you win $6. If you pick any other card, you lose $5. How much money do you expect to win?
Answer:
expected value = (13/52)(10) + (9/52)(8) + (30/52)(-6) = $.42
expected value is you win $.42, so you want to play

Fred started a new e-commerce business and borrowed 15000 for 12 years to get the business up and running. The interest is 18000. Find the rate
Answer:
The rate is 6.94 %
Step-by-step explanation:
Given;
Amount borrowed by Fred to start up the e-commerce, P = 15000
time of investment, t = 12 years
interest, I = 18000
The rate is given by the following equation;
P = IRt
R = P / It
where;
R is the rate
P is the principal
I is the interest
t is the time
R = (15000) / (18000 x 12)
R = 0.0694
R = 6.94 %
Therefore, the rate is 6.94 %

Leanna has a rectangular piece of fabric. The fabric is 24 inches wide and 40 inches long. Leanna folds the piece of fabric along its diagonal to form a triangular scarf.
What is the area, in square inches, of the triangular scarf?
Answer:
480 square inches
Step-by-step explanation:
width = base = 24 inches
length = height = 40 inches
area of the triangular scarf = 1/2 * base * height
= 1/2 * 24 * 40
= 480 square inches

Answer:
x = -3, -2, or 2
Step-by-step explanation:
In the graph, we can look along the line f(x)=6 and see where the function intersects, noting the x-coordinate of each value. We see that the coordinates with a y-value of 6 are (-3, 6), (-2, 6), and (2,6). This means that x can equal either -3, -2, or 2 when f(x)=6.

Answer:
D = 9(x, y, z) = (2, 3, -4)Step-by-step explanation:
A suitable calculator can compute the determinant for you. It is ...
D = 9
Then the values of x, y, z are ...
(x, y, z) = (Dx, Dy, Dz)/D = (18/8, 27/9, -36/9)
(x, y, z) = (2, 3, -4)
