Answer:
x = 3.75
Step-by-step explanation:
ABC is a right angled triangle.
Therefore, by Pythagoras theorem:
C) 500
Explanation:
The middle of the box and whisker plot is the line in the middle of the box. That line is over the number 500 on the number line meaning the C would be the correct answer.
Answer:
No, they're not. To find the area of a circle you need to square the radius. They did not square the radius but instead multiplied it by 2.

Answer:
no
Step-by-step explanation:
Given :
A skyrocket is launched from a 8-foot-high platform with an initial speed of 220 feet per second.
The polynomial -16t² + 220t + 8 gives the height in feet that the skyrocket will rise in t seconds.
To Find :
How high will the rocket rise if it has a 7-second fuse?
Solution :
Since, it is given that the rocket has a fuse time of 7 seconds.
Putting value of 7 sec in given equation, we get :
Height = -16×( 7 )² + 220×( 7 ) + 8
Height = 764 m
Therefore, height of rocket in 7 second fuse is 764 m.
