Answer:
S'(-16,1) and V'(-1,-23)
Step-by-step explanation:
It is given that SV has coordinates S(-6,1) and V(-1,-7).
We need to find the coordinates of S'V' after a dilation with a scale factor of 3 centered at (-1,1).
If a figure dilated by factor k and center of dilation is (a,b), then
SV dilated by scale factor of 3 centered at (-1,1).
SV has coordinates S(-6,1) and V(-1,-7). The vertices of image are
Therefore, the coordinates of S'V' after a dilation are S'(-16,1) and V'(-1,-23).
Answer:
7 inches
Step-by-step explanation:
area of square=l^2
49=l^2
=l
7=l
therefore the sides of a triangle is 7 inches.
B: 78.50
If you plug in 5 for r, then you get 3.14 * 25, which is equal to 78.5
Hope this helps!
Answer:
im just testing this but if you did that you would be slow as heck.
Step-by-step explanation:
17 minutes is decent so...
For question number 1:The plot H = H(t) is the parabola and it reaches its maximum in the moment when exactly at midpoint between the roots t = 0 and t = 23. At that moment t = 23/2 or 11.5 seconds.
For question number 2:To find the maximal height, just simply substitute t = 11.5 into the quadratic equation. The answer would be 22.9.
For question number 3:H(t) = 0, or, which is the same as -16t^2 + 368t = 0.Factor the left side to get -16*t*(t - 23) = 0.t = 0, relates to the very start of the process, when the ash started its way up.The other root is t = 23 seconds, and it is precisely the time moment when the bit of ash will go back to the ground.
