Answer:

A. 1.15 x $10^{2}$

Step-by-step explanation:

We can find out how many times larger is the diameter of the sun than the diameter of Venus by dividing the diameter of the sun by the diameter of Venus, and so we get...

1391000 / 12100 ≅ 115

115 is equal to 1.15 x $10^{2}$ , therefore the right answer is A.

Identify the initial amount a and the rate of growth r (as a percent) of the exponential function y=12(1.05)^t. Evaluate the fun

pentagon [3]

Answer:

Initial amount is 12

Rate of growth is 5%

At t = 5, y = 15.3.

Step-by-step explanation:

This is an exponential function. An exponential function has the form:

$f(x) = a_0(1+r)^t$ where the original/initial amount is $a_0$ , the growth rate is $1+r$ and the time is $t$ .

This means for the equation $y = 12(1.05)^t$ :

the initial amount is 12
the growth rate is 1.05 so the rate is 0.05 or 5%

Substitute t = 5 into the equation to find the amount at 5.

$y = 12(1.05)^5\\y = 12(1.276)\\y= 15.3$

Sophia needs to know the area and perimeter of his property. The length of his property is 1/5 mile and the width is 3/8 mile. W

denpristay [2]

Answer:

See the answers below

Step-by-step explanation:

Given data

Length = 1/5mile

Width= 3/8 mile

The expression for the perimeter

P=2L+2W

Substitute

P=2*1/5+ 2* 3/8

P= 2/5+6/8

P= 16+30/40

P=46/40

P= 23/40 miles

Area= Length *Width

Area= 1/5* 3/8

Area= 3/40 square miles
