Answer:
Step-by-step explanation:
In this problem we have a exponential equation of the form
where
y is the population of the city
x is the number of years
a is the initial value or y-intercept
b is the base
r is the rate of growth
b=(1+r)
we have
substitute
For x=17 years
substitute the value of x in the exponential equation and solve for y
I would choose Plan 2
Divide the number money by the number of square feet.
Plan 2 is $120 cost per square when you divide 288000÷2400=120.
Thats the least expensive for 1 square ft.
Answer
252
Step-by-step explanation:
12*12=144
18*6= 108
108+144=252
It's A because to remove the radical you do x-2 squared and 7 squared which you will get x-2=49 and then subtract -2 from 49 which gives you 51
Answer: C) Three-fourths
I.e., the fraction 3/4
======================================================
Explanation:
Let's pick on the horizontal sides. Divide the image length Y'Z' = 9 over the corresponding preimage length YZ = 12 to get
(Y'Z')/(YZ) = 9/12 = 3/4 which is the scale factor
The scale factor is less than 1, meaning the image's lengths are shorter compared to the preimage's corresponding lengths.
-----------------
Alternative Paths:
You can pick any other pair of corresponding sides to get the same result:
- (X'Y')/(XY) = (7.5)/(10) = 75/100 = 3/4
- (Z'X')/(ZX) = 6/8 = 3/4
