Pls help I don’t get it

Answer:

17

Step-by-step explanation:

f(x) = 3x + 2

Let x=5

f(5) = 3*5 + 2

Multiply first

    = 15+2

Then add

    = 17

Answer:

105˚, 75˚

Step-by-step explanation:

<2 is 75˚ by same side angles of a transversal.

<1 is supplementary to <2 so 180-75 = 105˚

Answer:

    When you're given a line, you can find the rise over the run also known as the slope using a graph, calculating it using the formula, or using a table with two points you've been given from the line. Once you find the slope find the y-intercept which is the point at which the line intercepts with the y-axis of the cartesian plane. I also added some attachments of my own work and an explanation of slope.

Hope I helped have a nice day :)

Answer:

8 [tex]\frac{2}{3}[/tex]

Step-by-step explanation:

Find the LCD of the two fractions, which is six

3[tex]\frac{1}{2}[/tex] = 3 [tex]\frac{3}{6}[/tex]

---------------------------------------------------------------------------------------------------------------

5[tex]\frac{1}{6}[/tex] + 3 [tex]\frac{3}{6}[/tex] = 8[tex]\frac{4}{6}[/tex]

The next step is to reduce:

The ASAP Math program provides an opportunity for additional small group instruction for students who find the math program challenging. Students in grades 1 to 4 will come to the ASAP room two to three times a week during the math block.

Step-by-step explanation:

6(f+4) + 2(f+4)

Use the distributive property:

6f+24 + 2f + 8

Now combine like terms:

8f +32

The answer is 8f + 32

Answer:

8 f + 32

Step-by-step explanation:

6 ( f + 4 ) + 2 ( f + 4 )

Distribute

6 × f + 6 × 4 + 2 × f + 2 × 8

6 f + 24 + 2f + 8

Collect like terms

6 f + 2 f + 24 + 8

Add the numbers

8 f + 32

Answer:

r = [tex]\frac{V-IR}{I}[/tex]

Step-by-step explanation:

Given

V = I (R + r) ← distribute parenthesis

V = IR + Ir ( subtract IR from both sides )

V - IR = Ir ( divide both sides by I )

[tex]\frac{V-IR}{I}[/tex] = r

Answer:

3/4

Step-by-step explanation:

We can use the slope formula when given two points

m = ( y2-y1)/(x2-x1)

    = ( 5-2)/(1 - -3)

    = (5-2)/(1+3)

    = 3/4

-10 and 9

-10×9=-90

-10+9=-1

Answer:

See answers below

Step-by-step explanation:

Given the function:

f(x) = 0.15x + 900

a) f(80) = 0.15(80) + 900

f(80) = 12 +  900

f(80) = 912

b)  f(120) = 0.15(120) + 900

f(120) = 18 +  900

f(120) = 918

c) f(200) = 0.15(200) + 900

f(200) = 30 +  900

f(200) = 930

d)  f(56) = 0.15(56) + 900

f(56) = 8.4 +  900

f(56) = 908.4

Answer:

The volume of the sphere is  523.60

Step-by-step explanation:

The formula for volume of a sphere is :

V = [tex]\frac{4}{3} \pi r^{3}[/tex]

The radius of this sphere is 5, so let's plug that into our equation.

V = [tex]\frac{4}{3}[/tex] · [tex]\pi[/tex] · [tex]5^{3}[/tex]

≈ 523. 59878

Rounded to the nearest hundreth that is 523.60.

Answer:

y = - 2x + 13

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = - 2 , then

y = - 2x + c ← is the partial equation

To find c substitute (4, 5) into the partial equation

5 = - 8 + c ⇒ c = 5 + 8 = 13

y = - 2x + 13 ← equation of line

Answer:

Step-by-step explanation:

slope=-2

now using slope intercet formof equation of straight line,we get

y=mx+b

or, y=-2x + b

y + 2x =b

2x + y=b ......................   eq(i)

since the line passes through the point (4,5) it satisfies the equation (i)

y=5 and x=4 so,

equation is 2x +y =b

2*4 + 5=b

8+5=b

13=b

substituting the value of b in eq(i)

2x + y=b

2x + y=13

2x + y-13=0  is the required equation of the line.

Answer:

Z = 65 Y = 115

Step-by-step explanation:

z+115 = 180

z=65

y + 65 +100+80= 360

y+245 = 360

y=115

Answer:

y = 115°

z = 65°

Step-by-step explanation:

*IMPORTANT* Straight line = 180° & Squares = 360°

1) 180° - 115° = 65°

z = 65°

2) 360° - 100° - 80° - 65° = 115°

Also, interior angles = exterior angles

5896

Given data set:

6283 5700 6381 6274 5700 5896 5972 6075 5993 5581 5972 6274 6075 5896

To calculate the 30th percentile;

i. Rearrange the given data set in ascending order.

5581 5700 5700 5896 5896 5972 5972 5993 6075 6075 6274 6274 6283 6381

ii. Use the following formula to get the index of the value at the 30th percentile.

N = p(n)

Where;

N = the number of data points at or below the intended percentile.

p = the intended percentile.

n = the number of points in the data.

In this case;

p = 30 percent = 0.3

n = 14

Substitute these values into the equation;

N = 0.3(14)

N = 4.2

iii. From the calculated index, find the value of the 30th percentile.

If the index is a whole number x, the desired percentile is the average of the values at index x and x+1.

For example if the index is 4, then the desired percentile is the average of the values at index 4 and 5. In our case, that will be;

[tex]\frac{5896+5896}{2}[/tex] = 5896

If the index is a decimal number, it is rounded up to the nearest integer. The value at the rounded index is the desired percentile.

For example, in our case, the index is 4.2 which when rounded up becomes 4.

Therefore, the data point or value at index 4 is the 30th percentile. From the arrangement in (ii) above, that will be 5896. i.e

5581 5700 5700 5896 5896 5972 5972 5993 6075 6075 6274 6274 6283 6381
