Answer 1

Answer:

I think its 6

Step-by-step explanation:

Answer 2

Answer:

Step-by-step explanation:

Outline

You could have 2 values. The way to get them is to take the square root of 25, c is double the value you get for the first step.  Why 25? Well you only have 1 other choice and that is the 1 that is in front of the x^2. That's not very helpful.

Formula

c = ± 2*sqrt(25)

Solution

c = ± 2 * sqrt(25)

c = ± 2 * 5

c = ± 10

Comment

Where does the ± come from?

You need to get + 25

If you have (x - 5)(x - 5) the last term will be -5 * - 5 = 25

Similarly you get the same result with (x + 5)(x + 5)

Remark

Make a very crude diagram of what these points look like. You will find that

(-8,6) is above (-8,3) (-3,6) is above (-3,3)

That gives you a hint about how to find the Length and width.

Givens

From (-8,-3) and (-3, 3) L = -8 - -3 = - 5

From (-8,6) and  (-8,3) w = 6 - 3 = 3

Solution

The length cannot be minus 5. The way to get around that is to call it and absolute value of (-5) which is 5

So the area = L*W

area = 5 *3

area = 15

Answer

Area = 15

What is the radius of a circle that has a circumference of 3.14 meters?​

Answers

given:

circumference= 3.14m

to find:

the radius of the circle

solution:

Circumference of a circle = 2πr

Given, circumference = 3.14 meters

Therefore:

2πr = Circumference of a circle

2πr = 3.14

2 × 3.14r = 3.14,[Putting the value of pi (π) = 3.14]

6.28r = 3.14

r = 3.14/6.28

r = 0.5

Can somebody help me round 376.77 to the nearest whole. With steps (guidance)
It would totally help me with the state exam tomorrow!

Answers

The answer is 377

6.77 is close to 7 than 6 so you round up. That will get you to 7. So it will be 377

Answer:

To round 376.77 to the nearest dollar consider the tenths’ value of 376.77, which is 7 and equal or more than 5. Therefore, we have to round the amount up: the dollar part of 376.77, 376, increases by 1 to 377, and the decimal point and all digits (.77) are removed.

Step-by-step explanation:

It is given that, The circumference of a circle is 198 cm and we are to find the radius of the circle.

Answer:

If one counts the blocks on the graph from the school to the stadium and back, there are three blocks one way and three blocks going back.

Altogether 6 blocks.

If Catelyn lives halfway between the park and the school, the amount of blocks is 5.

3. -1/3  ± 2i√5 / 3

Step-by-step explanation:

3x^2 + 2x = -7

Divide through by 3:

x^2 + 2/3 x = -7/3

Completing the square:

x^2 + 2/3 x + (1/3)^2 = -7/3 + (1/3)^2

(x + 1/3)^2 = -7/3 + 1/9

(x + 1/3)^2 = -20/9

x + 1/3 =  ±√(-20) / 3

x + 1/3 = ± 2√-5/3

x  = -1/3  ± 2i√5 / 3

proportionality of triangles- setup and solve

Answers

You can set up proportions with similar triangles by taking advantage of their side ratios.
By definition, similar triangles have the same angle measures for their corresponding angles, and therefore the corresponding sides have a ratio to them.
For examplle consider the triangles below:
Image from regentsprep
Image from regentsprep
It is given that their corresponding angles have the same measurement, so therefore we can say that they are similar.
Now if we were asked to solve for side ED, then we could do so by setting up a proportion using the side ratios as follows:
AC/DF=CB/FE=BA/DE

Now we can just plug in the lengths for the respective sides:
7/14=6/12=10/DE

Now we can just simplify and solve:
1/2=1/2=10/DE
10/DE=1/2
DE=2(10)=20
This is how we can use proportions to solve for side lengths in similar triangles.
Just make sure you set up your proportions with the corresponding sides, or your ratios might come out wrong.
Just as a fun fact, the fact that side lengths have ratios when the angles are the same is fundamental in trigonometry as well, as you use side ratios there too.
Hope that helped :)

The future cost of the house will be $___
(Round to the nearest cent as needed.)

Answers

The house will cost approximately $246,359.85 seven years from now.

What is compound interest?

It is the interest we earned on the interest.

The formula for the amount earned with compound interest after n years is given as:

A = P [tex](1 + r/n)^{nt}[/tex]

P = principal

R = rate

t = time in years

n = number of times compounded in a year.

We have,

In this problem,

P = $140,000

r = 0.07

n = 1 (compounded annually)

t = 7.

Plugging in these values.

A = $140,000 (1 + 0.07/1)^(1 x 7)

A = $140,000 (1.07)^7

A = $246,359.85

Therefore,

The house will cost approximately $246,359.85 seven years from now.

b) 70.6 mph
c) 69.4 mph
d) 68.2 mph

Answers

Answer:

b) 70.6

Step-by-step explanation:

To calculate average you need to add up all the numbers and divide by the quantity of numbers. They are calculating with mph, with ten hours, so there will be ten numbers. First you do 73 x 6 (6 because of 6 hours of 73 mph) which is 438. Then you do 67 x 4 which is 268. you add it up, then find a total of 706. Then you divide it by ten to find the answer 70.6
