F(x)=-3.25x +22.41
f(-4.2)= 3.25(-4.2)+22.41 = 8.76
1: Assuming this line is linear, the first thing to do is find the slope.
The slope formula is
, so in this case, it is
, which comes to
. Then, use your slope and one of the points given to write the point-slope formula of the linear equation, and then written in standard form:
y=
x-
.
2. Use the same process as in question 1 to find:
y=-7x+11
Answer: 1:52 PM
Step-by-step explanation:
PAULA: 2:14PM FINISHED THE RACE
BEATRICE: FINISHED 22 MINUTES EARLIER THEN PAULA
YOU TAKE 2:14PM AND SUBTRACT THE 22 MINS BEATRICE RAN TO GET YOU ANSWER.
SO 2:14 -14 MINS=2:00PM 14+8=22 (THE MINS BETRICE FINISHED)
2:00-8 MINS ( REMAINING FROM THE 22 ) THEN 2:00-8 MINS =1:52
ANSWER:1:52PM
Answer: 90
Step-by-step explanation: it said i was right
The volume of any solid whose base is uniform is V = Ah. Since
the base is a sector of a circle, it’s area is defined by the equation A = θ (r^2)/2, where θ is in radians.
90 degrees in radians
is Pi/2. So the A = (PI) (r^2)/4
Therefore, V = [(PI) (r^2)/4]*h
