Answer:
By using completing the square method, equation (x - 12) (x + 4) = 9 can be solved as x = (4 + √ 73) or (4 - √ 73)
Answer = 36.0 mph
As per the question,
Actual speed of the car = 40 mph.
Speedometer has a percent error of 10%.
The error can be negative as well as positive.
If the error is negative, it means speedometer is showing less speed than actual speed= - 10%
10 % of 40 = 4
speed shown by speedometer = 40 - (10% of 40) = 36 mph
If the error is positive, it means speedometer is showing more speed than actual speed = +10%
speed shown by speedometer = 40 + ( 10% of 40) = 44 mph
as per the given options, correct option is 36.0 mph
Answer:
Ratio = 
Step-by-step explanation:
Volume of Sphere is given by the formula:

Where
V is the volume
and
r is the radius
Original Volume, given r = 3, would be:

Increased snowball volume:
Radius increased 0.25 per second, he spent 4 seconds, so radius increase:
0.25 * 4 = 1 cm
New radius = 3 + 1 = 4 cm
New Volume would be:

Ratio of New Volume to Original would be:

This is the ratio for current volume to original volume.
Do 9000 times 94%
Add it to 9000
Total sum is your answer
ANSWER -
1232323 ÷ 232 x 3 = 15935.2112069
It is cray cray lol.
Plz give brainliest I would rlly appreciate it :)
