Hi, thank you for posting your question here at Brainly.

This problem could be solved using the Law of Cosines, since we are given with the three sides. The equation goes,

b^2 = a^2 + c^2 - 2accosB. Substituting,

24^2 = 7^2 + 25^2 - 2(7)(25)cosB

Then B = 73.7 degrees. Therefore sinB or sin(73.7) = 0.96.

Solve for x. In the equation 9x +1/3= x-13

Xelga [282]

Answer:

Step-by-step explanation:

9x+ $\frac{1}{3}$ =x-13

9x*3+1/3=x-13

27x+1/3=x-13

27x+1=3(x-13)

27x+1=3x-39

27x-3x=-39-1

24x=-40

x=-5/3

Rework problem 15 in section 2 of Chapter 5 of your textbook about the growing suburb and the declining city using the following

bazaltina [42]

Answer:

16 years.

Step-by-step explanation:

Please consider the complete question.

Assume that the suburb has a population of 686,000 and is growing at a rate of 4000 per year. Assume that the city has a population of 942,000 and is declining at a rate of 12000 per year. In how many years will the populations of the suburb and the city be equal?

Let x represent number of years.

Growth function would be $G(x)=4000x+686,000$ and decline function would be $D(x)=942,000-12,000x$ .

To find the time when both populations will be equal, we will equate both functions as:

$4000x+686,000=942,000-12,000x$

$4000x+12,000x+686,000=942,000$

$16,000x+686,000=942,000$

$16,000x=942,000-686,000$

$16,000x=256,000$

$\frac{16,000x}{16,000}=\frac{256,000}{16,000}$

$x=16$

Therefore, in 16 years the populations of the suburb and the city will be equal.

What is five×fivewhat is the answer for 4 x 5

Mandarinka [93]

Well
<span>
4 x 5 = 20

and

5 x 5 = 25

I'm sure a calculator could help you out with this, But if you don't have access to a calculator I'll show you how to multiply. It's just like adding, Let's use 6 x 7 for example. Take the first number ( Which is 6 in this case ) and look at the second number ( Which would be 7 ) The second number represents how many times you would add the first number together. So:

6 + 6 + 6 + 6 + 6 + 6 + 6 = 42 ( We add 6 together 7 times )

So

6 x 7 = 42

There are faster methods but this is probably the best way to start out.
