Answer:
805.5 out of 900
Step-by-step explanation:
A test is out of 100 and because there are 9 tests: 9 x 100 which equals 900.
To get the average we add up each test mark and divide by the number of tests. The same can be applied here but reversed. So because there were 9 tests we can multiply 89.5 by 9 which gives us 805.5. Beverly scored 805.5 marks out of 900 which makes her average 89.5% for 9 tests.
It’s A 18.7 good luck hope you ace it

Answer:
Step-by-step explanation:answer is look it up
The rate of change for the points (x1,y1) and (x2,y2) is (y2-y1)/(x2-x1)
given
y=5x^2 and find the slope between x=-2 and x=6
y=6(-2)^2=6(4)=24
y=6(6)^2=6(36)=216
(-2,24)
(6,216)
slope=(216-24)/(6-(-2))=(192)/(6+2)=192/8=96/8=48/4=24/2=12
the rate of change is 12
