Answer:

y = 2x + 3

Step-by-step explanation:

x = 1 , y = 2(1) + 3 = 5

x = 2, y = 2(2) + 3 = 7

x = 3, y = 2(3) + 3 = 9

x = 4, y = 2(4) + 3 = 11

x = 5, y = 2(5) + 3 = 13.

The data set that is more likely to produce a histogram with a symmetric distribution is data on the number of seconds on a track of music in a pop album.

Data on a histogram have a symmetric distribution if the left side and the right side of the histogram are mirror images of each other.

It is likely that the number of seconds on a track of music in a pop album would be relatively uniform. Thus, it is likely to have a symmetric distribution. The number of seconds spent talking on the phone varies greatly.

Answer:

a) angle QRP is 92 degrees, side QR is 23 cm, angle RPQ is 47 degrees

b) angle EFD is 65 degrees, side FD is 22cm, side ED is 20cm

Step-by-step explanation:

a) in the first example, you know that u are given QR, PR, and angle PRQ, and u are asked to find triangle PQR,or the rest of the lengths.

step 1-u draw an example of the triangle, i will provide one for each at the bottom of this answer

step 2-lets find the sides first with the pythagorean theorem, which will mean 25²+x²=34². Pythagorean theorem is a²+b²=c²

step 3-after solving for x, x will be 23.04, which means the third side is 23 cm (after rounding).

step 4-now that we have all the sides, we can solve for the rest of the angles, by trigonometric ratios, we are gonna use sine for angle RPQ, sine is sin(the angle u want to find)=opposite side/hypotenuse.

step 5- so sin(RPQ)=25/34, and solve for RPQ on a calculator (i used math) and angle RPQ will equal 47.3 degrees.

step 6- just subtract the sum of both angles from 180 an the last angle will be 92 degrees.

b) u are given the measure of angles FED and EDF and the side length FE, we will solve for the last angle first then we will go for the side engths

step 1- we subtract the sum of the two angles we have from 180 and we will get the measure of angle EFD to be 65 degrees, now we have the angles and we want to find he sides.

step 2-we use sine of angle 31 degrees to find the hypotenuse, but it is opposite of sine since we want to find the side, not the angle, so we will use sin(31)=11.3/x, the sine equation is written like sin(the angle u have)=opposite/hypotenuse.

step 3- after solving for arc sine in a calculator, u will find side FD to be 22cm, and now to find the last side.

step 4-i will use the sine of angle 65 degrees to solve for side ED, it will be sin(65)=x/22, which will make side ED equal 20 cm in length.

Step-by-step explanation:

The equation of the line that is perpendicular to y = -5/2 x + 1 and passing through (10, 3) will be y = 2/5 x + 1.

A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.

The equation of the perpendicular line will be given as

y = mx + c

The given equation is y = -5/2 x + 1.

The slope of the line is -5/2.

Then the product of the slope of the perpendicular lines is a negative one.

-5/2 × m = - 1

m = 2/5

Then the equation will be

y = 2/5 x + c

Then the equation is passing through (10, 3). Then we have

3 = 2/5 × 10 + c

3 = 2 + c

c = 1

Then the equation is y = 2/5 x + 1.

Answer:

C) -5 is located to the LEFT of 2

Step-by-step explanation:

On a number line, of course the negatives (-) are to the left while the positives (+) are to the right, so since -5 is negative, and 2 is positive, -5 is located to the LEFT of 2.

Answer:

mean = 34

Step-by-step explanation:

the mean is calculated as

mean = [tex]\frac{sum}{count}[/tex] = [tex]\frac{20+28+30+38+39+40+43}{7}[/tex] = [tex]\frac{238}{7}[/tex] = 34

Answer: 34

Step-by-step explanation:

Mean is the same as average, and to find average you add all the numbers up and divide by the amount of numbers present. So, if you add all of them up, you get 238. Then, you'll divide by 7, since there are 7 numbers. And that will get you 34.

Answer:

Step-by-step explanation:

The area of the cube using the distance formula is 16 square units and each side measure is 4 units.

It is defined as three-dimensional geometry that has six square faces and eight vertices.

We have a cube shown in the picture.

Area of the cube = 16 square units

Area of cube = side²

Side = √16 = 4 units

Each side of the cube = 4 units.

From the attached figure, we can see each side lies on each quadrant.

Using the distance formula, we can calculate the distance between two

points:

[tex]\rm d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

The area of the cube = 4×4 = 16 square units

Thus, the area of the cube using the distance formula is 16 square units and each side measure is 4 units.

Since the lens is 2.9 inches wide, the total thickness of the lens is 0.29 in

To answer the question, we need to know what equations are.

Equations are mathematical expressions which show the relationship between two variables.

Since f(x) = x²/58 describes half the thickness of the lens where x  = width of lens.

So, the total thickness of the lens is y = 2f(x)

= 2 × x²/58

= x²/29

Since x = 2.9 in, substituting x into the equation, y, we have

y = x²/29

y = (2.9)²/2

y = 8.41/29

y  0.29 in

So, the total thickness of the lens is 0.29 in

The two terms on the left side both have a common factor of (sin(α) + cos(β)), so we can pull it out like so:

(sin(α) + cos(β))² + (cos(β) + sin(α)) (cos(β) - sin(α))

= (sin(α) + cos(β)) [(sin(α) + cos(β)) + (cos(β) - sin(α))]

= (sin(α) + cos(β)) (sin(α) + cos(β) + cos(β) - sin(α))

= 2 cos(β) (sin(α) + cos(β))
