Solve for c:

5(8 + c) = 55

answer choices

c = 3

c = 11

c = 5

Answers

C equals 3 cause 5 x8 is 40 5 x 3 is 15 40 plus 15 is 55
We want to divide both sides of the equation by 5 to get 8+c by itself and then subtract 8 from both sides to get c by itself

state the vertices, foci, and asymptotes of the hyperbola with the equation
20x^2-25y^2=100
PLEASE SHOW YOUR WORK SO I CAN UDERSTAND!!!

Answers

To find the vertices, foci, and asymptotes of the hyperbola with equation 20x^2 - 25y^2 = 100, we need to first write the equation in standard form:

(x^2)/(5) - (y^2)/(4) = 1

From this equation, we can see that the hyperbola has a horizontal transverse axis, since the x^2 term is positive and is divided by a smaller number than the y^2 term. Therefore, the center of the hyperbola is (0,0).

Using the standard form of the hyperbola, we can find the values of a and b:

a^2 = 5, so a = sqrt(5)
b^2 = 4, so b = 2

Now we can find the vertices, foci, and asymptotes:

Vertices:
The vertices are located at (±a,0), so the vertices are at (-sqrt(5),0) and (sqrt(5),0).

Foci:
The foci are located at (±c,0), where c = sqrt(a^2 + b^2). Plugging in our values of a and b, we get:

c = sqrt(5+4) = sqrt(9) = 3

So the foci are at (-3,0) and (3,0).

Asymptotes:
The equations of the asymptotes are y = ±(b/a)x, so the equations of the asymptotes are:

y = ±(2/sqrt(5))x

Therefore, the vertices are (-sqrt(5),0) and (sqrt(5),0), the foci are (-3,0) and (3,0), and the equations of the asymptotes are y = ±(2/sqrt(5))x.

A thunderstorm cloud holds about 6,200,000,000 raindrops. Which of the following shows this number in scientific notation? Answers- F- 0.62*10 to the 10th power G- 6.2*10 to the 9th power H- 6.2*10 to the 8th power J-62.0*10 to the 8th power

Answers

Answer:

the answer is G

which is 6.2*10 to the 9th power.

Step-by-step explanation:

In scientific notation you must leave one digit to the place value of ones

so that one digit is 6

So ue come up with 6.2 when ue eliminate all other zeros and end the decimal point between 6 and 2 and that way you have 6.2*10 to the 9th power

Answer:

G, 6.2*10 to the 9th power.

Find the equation of the line that passes through (-3,1) and is parallel to y=1−2x.
Leave your answer in the form y=mx+c

Answers

Answer:

y=-5-2x

Step-by-step explanation:

The equation of the line in the slope-intercept form is y=1-2x.

The slope of the parallel line is the same m=-2

So, the equation of the parallel line is y=-2x+a

To find a, we use the fact that the line should pass through the given point: 1=(-2)×(-3)+a.

Thus, a=-5

Therefore, the equation of the line is y=-5-2x

Joseph graphs how much money he makes per hour on his newspaper delivery route. He finds that the graph tends to be linear and draws a line that passes through the points (3,16.5) and (8,44). About how much does he earn per hour?
A. $5.00 C. $6.00
B. $5.50 D. $6.50

Answers

The answer is A because it says earn per hour so u get the number

The amount of money that Joseph earns in an hour is $5.50.

What is Linear Function?

A linear function can be defined as the function whose graph is a straight line. It can also be defined as the function with one or more variables and the exponent of the variable is 1.

Given that the graph of how much money Joseph making per hour on his newspaper delivery route is linear.

If the function is linear, then the slope must be constant.

The graph will be proportional since the amount of money he earns in 0 hour will be 0.

So, the money he makes per hour is equal to the slope of the line.

Slope of a line given two points = Change in y coordinates / Change in x coordinates

Given points (3,16.5) and (8,44).

Slope = (44 - 16.5) / (8 - 3) = 5.5

Hence the amount he earn per hour is $5.50.

Answer: Range and mean = 8 of both

variance of Set X= 4.7

variance of Set Y= 4.6

Step-by-step explanation:

Two sets of data, set X and set Y are given

a.) Range is the difference of the highest value and the lowest value,

Therefore, Range of set X = 12-4=8

Range of set Y = 12-4=8

Now, Mean of a given data set is the average of all the terms present in the given data set

Mean of set X= Σxif/n = (4+5+6+7+16+18+24)/10 = 8

Mean of set Y= (4+5+7+32+20+12)/10= 8

Therefore, both the data sets has same range and mean.

b.) Standard deviation tells about the variability of the date and is given by,

S.D= σ = √∑ ( X − μ )^2/n

S.D of set X= √(16+9+4+1+0+1+16)/10= √4.7

S.D of set Y= √(16+9+1+0+4+16)/10= √4.6

Variance is the square of S.D, that is, σ^2

Therefore, variance of set X=4.6

variance of set Y= 4.7

c.) The calculated variances of set X and set Y are 4.7 and 4.6 respectively. It implies that the data is more distributed or varied in set X than in set Y. In the other words, data in set Y is more consistent data than of set X.

Given line AB, use similar triangles to prove that the slope of line AB is the same between any two points on the line.


1. Create two similar, but not equal, right triangles using segments of line AB as the hypotenuse of each triangle. For the first right triangle use point A(-5,-1) and choose another point on the line to form the hypotenuse. For the second right triangle use point B(4,3.5) and choose another point on the line to form the hypotenuse. For each point used to create the triangles, name the point with a capital letter and coordinates. For example, the triangle using point A could be named ΔACE and the triangle using point B could be named ΔBDF.
2. For the pair of similar triangles created in Part 1, list three pairs of corresponding angles that are equal and three sets of proportionate sides.
3. Use the pair of similar triangles created in Part 1 to demonstrate that the slope of line is the same between any two points on the line.
