(D)
The high school's enrollment in 2017 is 2500
Step-by-step explanation:
Let's assume time starts since 2009
so, In 2009 , t=0
P=900
In 2012,
t=2012-2009=3
P=1500
(A)
So, we have points as
(B)
we can use slope formula
we can plug values
we know that
slope is rate of change of P with respect to time
so, slope means increase in population is 200 per year
(C)
we can use point slope form of line
(D)
In 2017 ,
t=2017-2009=8
we can plug t=8
and we get
The high school's enrollment in 2017 is 2500
Answer:
fourth and fifth
Step-by-step explanation:
If George gets a 20% raise, that means he will now earn
$445 + $445*20% = $445 + $445*0.2 = $445*1 + $445*0.2 = $445*(1 + 0.2) = $445 * 1.2
So we know the fourth is correct.
We also know that current pay is 100% of current pay and the new pay will be 120% of current pay, so x/455 must be equal to 120% / 100% which is equal to 120/100, so fifth is correct too.
After 2 minutes, temperature = 9/10 x 70 = 63F
After 4 minutes, temperature = 9/10 x 63 = 56.7F
After 6 minutes, temperature = 9/10 x 56.7 = 51.03F
Answer:
Step-by-step explanation: I will help you with some of them. For the first one the diameter is 18 because diameter is 2x radius. For number 3. The radius is 2. For number 6. The radius is 13. For number 7. The radius is 17. And for number 9. Diameter is 30
First subtract the amount the bow takes from the total:
70 - 32 = 38 inches
The width is 14 on top and bottom so subtract 14 x 2 = 28 from 38:
38-28 = 10
Divide 10 by the 2 sides:
10/2 = 5
The height is 5 inches.
