A rotation of 90 degrees changes (x,y) to (-y,x). If the original coordinates if point F is (0,3), after a rotation of 90 degrees it would be (-3,0).
Answer:
The rocket will take 9.25 seconds to return to ground
.
Solution:
Given:
Initial velocity = 148 ft per seconds
Height "h" after "t" seconds is given by equation:
To find:
Time taken by rocket to return to ground =?
Solution:
The time taken by rocket to return to ground can found by substituting h(t) = 0 in the given equation.
Taking t outside
t(-16t + 148) = 0
Zero product property. The zero product property states that if a⋅b = 0 then either a or b equal zero. This basic property helps us solve equations like (x+2)(x-5) = 0
So for above equation we get,
t =
t = 9.25
When t = 0 , the rocket would not left the ground. So ignore t = 0
So t = 9.25
It is isometric because all side lengths and angle measures remained the same.
I hope this help.
Answer:the answer is a.
Step-by-step explanation:i just took a test with this question on it.
Gradient of AB = y1-y2/x1-x2
= -3-0/1-1
= -3/0
gradient of AB = gradient of CD (as AB is parallel to CD)
therefore D = 3+y3/0+x3
= -3+2/0+4
= -1/4
since y/x of D = -1/4,
the coordinates of D is (4,-1) [option B]

hope this helps! :)))
