I believe the center would be (-4,2) while the radius should be 3.

The quotient of a secret number and 4 is 9

Anna [14]

Let's call the 'secret number' x.

A quotient is basically a Dividend/Divisor. If the Divisor is 4, we need to find the dividend, which is x.

Therefore:
x/4=9
We need to isolate the variable by the multiplication property of equality.
x=36.

As a result, the "secret number" is 36

Let 3.27<<5.89 represent an interval on the number line. Find the value that is in the middle of the interval.

laila [671]

Answer:

The middle value of the interval is 4.58

Step-by-step explanation:

Consider the provided interval.

We need to find the value that is in the middle of the interval.

We can find the middle value of the interval by adding the upper and lower limit and divide the sum of the upper and lower limits by 2.

Here the upper limit is 3.27 and lower limit is 5.89.

$\frac{3.27+5.89}{2}=\frac{9.16}{2}=4.58$

Hence, the middle value of the interval is 4.58

The value of a treadmill bought new for $1000 decreases 5% each year. Use a graph to predict the value of the treadmill in 5 yea

Georgia [21]

The formula is
V (t)=V0 (1-r)^t
V (t)?
V0 1000
R 0.05
T 5 years

V (5)=1,000×(1−0.05)^(5)=773.78
