Step-by-step explanation: it is in its most simplified form

Functions can be modeled by equations, tables and graphs

From the question, we have the following ordered pairs

(x,y) = (0,1) and (4,2)

The function is a linear function.

So, we start by calculating the slope (m) using:

[tex]m = \frac{y_2 - y_1}{x_2 -x_1}[/tex]

Substitute known values

[tex]m = \frac{2 - 1}{4 - 0}[/tex]

[tex]m = \frac{1}{4}[/tex]

The equation is then calculated as:

[tex]y = m(x -x_1) +y_1[/tex]

This gives

[tex]y = \frac 14(x -0) +1[/tex]

[tex]y = \frac 14x +1[/tex]

The domain of the above function is the set of whole numbers

Substitute 10 for x, to calculate the number of box office gross for week 10

[tex]y = \frac 14 * 10 +1[/tex]

[tex]y = 3.5[/tex]

Approximate

[tex]y = 4[/tex]

Hence, the company should expect 4 box office gross in week 10

Answer: Y= 1/2X+5

Step-by-step explanation: Equation of the line

The slope-intercept form of a line is given by:

Being:

m = the slope of the line

b = the y-intercept

We can also use the point-slope form of the line:

Being:

(h,k) = A point that belongs to the line

Two lines of slopes m1 and m2 are perpendicular if:

We are given the line:

Whose slope is m1=-2

Answer:

y= 95.

180°-120°=60° (adding 120° with x should give you 180°)

x=60°

25°+60°=85°

180°-85°=95

Answer:

y=95

Step-by-step explanation:

we know that the triangle angles sum is 180°

to find Y you should find x

we are going to find x, we know that a straight angle is 180, to find the x you should:

[tex]120+x=180[/tex]

move 120 to the other side with a negative sign:

[tex]x=180-120\\x=60[/tex]

angle [tex]x=60[/tex]

now we know enough angles to find y:

[tex]25+60+y=180[/tex]

25 is given in the picure and 60 is the x angle while 180 is the sum of a triangle angles, we have to flip the equaton to find y:

[tex]25+60+y=180\\85+y=180\\y=180-85\\y=95[/tex]

Answer: The square is 32

Step-by-step explanation:

In - order to find the size of the square you must do width times height . . .

What is 4 x 8 ? 32

Answer:

1 minute

Step-by-step explanation:

1km = 1000m

30km = 30000m

30km ÷ 60 = 500m

it takes one hour to go 30km or a ratio of 30km to 1hour. 1hour is also 60minutes. 30:60

divide both sides by 60 gets 500m and the amount of time to go that distance 1 minute

Answer:

1/60 hr or 1 minute

Step-by-step explanation:

30 km per hour

30 km : 1 hr

convert 500 metres to km

1 km = 1000 metres

500 ÷ 1000 = 0.5 km

using ratios

30 km : 1 hr

0.5 km : x hr

to get from 30 to 0.5 multiply by 1/60 ( we got this from doing 0.5 ÷ 30) , so do the same to the other side

1 hr × 1/60 = 1/60 hr

you can convert to minutes = 1/60 × 60 = 1 minute

Excel formulas are expressions used to perform computation.

From the complete question, cell B21 represents base work hour

So, we start by checking if the work hour in cell D5 is less than the base work hour in cell B21

If yes, the work hour remains D5; otherwise the work hour is cell B21

The work hour is then multiplied by the rate in cell C5

Hence, the Excel formula to enter in cell E5 is =IF(D5<$B$21,D5,$B$21) *

Here, we start by checking if the work hour in cell D5 is greater than the base work hour in cell B21

If yes, the overtime hour the difference between D5 and B21; otherwise the overtime hour and pay is 0

The over time hour if there is, is then multiplied by the rates in cells C5 and B22

Hence, the Excel formula to enter in cell E5 is =IF(D5>$B$21,(D5-$B$21) * C5 * $B$22, 0)

Answer:

210 cm³

Step-by-step explanation:

volume = W x L x H

(where W = width, L = length and H = height)

By inspection of the diagram,

W = 6 cm

L = 7 cm

H = 5 cm

Therefore, volume = 6 x 7 x 5 = 210 cm³

Answer:

210 cm³

Work:

6×7=42

42×5=210

Step-by-step explanation:

When finding volume of a cube or rectangular prism you do the same thing as when you find the area of a square or rectangle, which is multiply the dimensions.

We see it is 7 cubes long, 6 cubes wide, and 5 cubes tall. To find the volume multiply all of these values together.

7×6×5=210

So, the volume of the prism is 210 cubes. Sense each cube is 1 cm³ the answer to the problem is 210 cm³

Hi! I will help you with a smile!

First of all, we have the slope of the line and a point that it passes through.

Let’s write the line’s equation in Point-Slope Form:

y-y1=m(x-x1)

Where

y1 is the y-coordinate of the point, m is the slope of the line, and x1 is the x-coordinate.

In this case, y1=-4, m=-6, and x1=3

Solve:

y-(-4)=-6(x-3)

y+4=-6x+18

y=-6x+18-4

y=-6x+14 (Answer)

Answer:

y = -6x+14

Step-by-step explanation:

m = -6 ,given as x an y (3,-4)

solution y-y1 = m(x-x1)

y-(-4) = -6(x-3)

y+4 = -6x+18

then y = -6x+18-4

B                    C

Points A, B and C represent this problem. BC is 3ft, AC is 10ft and AB is x, now we sub this information into pythagoras theorem formula

3^2+b^2=10^2

Rearranged this is,

b^2=10^2-3^2

b^2=91

b=[tex]\sqrt{91}[/tex]
