Answer:

$4\frac{1}{5}$

Step-by-step explanation:

=> $\frac{7}{9} * 5 \frac{2}{5}$

=> $\frac{7}{9} * \frac{27}{5}$

=> $\frac{7*3}{5}$

=> $\frac{21}{5}$

=> $4\frac{1}{5}$

Answer:

$4\frac{1}{5}$

Step-by-step explanation:

$\frac{7}{9} \times 5 \frac{2}{5}$

$\frac{7}{9} \times \frac{27}{5}$

$\frac{7 \times 27}{9 \times 5 }$

$\frac{189}{45}$

$\frac{21}{5}$

$=4\frac{1}{5}$

a_sh-v [17]

we know that

$5 \frac{3}{10}= \frac{5*10+3}{10} = \frac{53}{10}$

Step 1

Carlos's method

1) Find the absolute value of $-\frac{53}{10}$

$\left|-\frac{53}{10}\right|=\frac{53}{10}$

2) Find the opposite

$opposite=-\frac{53}{10}$

Step 2

Jason's method

1) Find the opposite of $-\frac{53}{10}$

$opposite=\frac{53}{10}$

2) Find the absolute value

$\left|\frac{53}{10}\right|=\frac{53}{10}$

Step 3

Compare the answers

$\frac{53}{10} > -\frac{53}{10}$

therefore

The answer is

The greater value is obtained with the method of Jason

1. )The function f(x)=12,500(0.87)^x models the value of a car x years after it is purchased.

sweet-ann [11.9K]

1] Given that the value of x has been modeled by f(x)=12500(0.87)^x, then:
the rate of change between years 1 and 5 will be:
rate of change is given by:
[f(b)-f(a)]/(b-a)
thus:
f(1)=12500(0.87)^1=10875
f(5)=12500(0.87)^5=6230.3
rate of change will be:
(6230.3-10875)/(5-1)
=-1161.2
rate of change in years 11 to 15 will be:
f(11)=12500(0.87)^11=2701.6
f(15)=12500(0.87)^15=1,547.74
thus the rate of change will be:
(1547.74-2701.6)/(15-11)
=-288
dividing the two rates of change we get:
-288/-1161.2
-=1/4
comparing the two rate of change we conclude that:
The average rate of change between years 11 and 15 is about 1/4 the rate between years 1 and 5.
The answer is D]
2] Given that the population of beavers decreases exponentially at the rate of 7.5% per year, the monthly rate will be:
monthly rate=(n/12)
where n is the number of months
=7.5/12
=0.625
This is approximately equal to 0.65%. The correct answer is A. 0.65%
