In a scale model of the Eiffel Tower, 10 centimeters represent 65 meters. If the real Eiffel Tower is approximately 325 meters tall, how tall is the plastic model?

Answers

Answer:

The plastic model is 50 meters tall

Step-by-step explanation:

Here, we want to know how tall is the plastic model

In the plastic model 10 m represents 65 meters

then x meters plastic = 325 m real

10 * 325 = 65 * x

3250 = 65x

x = 3250/65

x = 50 meters

Linear function f is shown in the graph. Write the slope-intercept form of the equation representing this function.

Answers

Y=3x-7 more characters because the app won’t let me put only the answer

The equation representing the function f(x) -

y = 4x - 8

We have a linear function f(x) as shown in the graph.

We have to determine the slope-intercept form of the equation representing this function.

What is the Slope - intercept form of the equation of a straight line ?

The Slope - intercept form of the equation of a straight line is as follows -

y = mx + c

where -

m - slope of line

c - intercept of line on y - axis.

According to the question, we have -

c = - 8 = intercept of line on y - axes.

Intercepting coordinates on  y - axes = (0, -8).

Intercepting coordinates on x - axes = (2, 0).

Slope = m = [tex]\frac{-8-0}{-2 -0}[/tex] = 4

Therefore, the equation representing the function f(x) -

y = 4x - 8.

What are the points for y=-3x+4 and how do I graph it

Answers

Answer:

(-3,13) (-2,10) (-1,7) (0,4) (1,1) (2,-2) (3,5) (4,8)  are your graph points.

Step-by-step explanation:

Okay so to find the points, you have to create a table graph with a set of x values.

in this case, your equation y=-3x+4 the x can be replace with a set of numbers and these will be your plots.

-3(-3)+4= 13

-3(-2)+4= 10

-3(-1)+4= 7

-3(0)+4= 4

-3(1)+4= 1

-3(2)+4= -2

-3(3)+4= -5

-3(4)+4= -8

Naturally with these points a shape will form ideally a straight line. Hopefully this helps and good luck!

The graph shows the relationship between the time in minutes and the number of milk cartons that Machine 1 can fill. The equation y = 22x describes the rate at which Machine 2 can fill cartons where x is the number of minutes and y is the number of cartons filled. PART A What is the unit rate for each machine? PART B Which machine can fill cartons at a faster rate? How much faster?

Answers

Answer:

A. 25, 22

B. machine 1

How much faster? MACHINE 1 fills 3 more cartons per minute than MACHINE 2

Step-by-step explanation:

Machine 1's unit rate = 25 and Machine 2's unit rate = 22. Machine 1 fills cartons faster and fills 3 more cartons per minute than machine 2.

What is the general equation of a Straight line?

The general equation of a straight line is -

[y] = [m]x + [c]

where -

[m] is slope of line which tells the unit rate of change of [y] with respect to [x].

[c] is the y - intercept i.e. the point where the graph cuts the [y] axis.

The equation of a straight line can be also written as -

Ax + By + C = 0

By = - Ax - C

y = (- A/B)x - (C/A)

We have graph that shows the relationship between the time in minutes and the number of milk cartons that Machine 1 can fill. The equation y = 22x describes the rate at which Machine 2 can fill cartons where x is the number of minutes and y is the number of cartons filled.

The equation of the graph that shows the relationship between the time in minutes and the number of milk cartons that Machine 1 can fill is -

y = [(100 - 50)/(4 - 2)]x

y = 25x

AND

y = 22x describes the rate at which Machine 2 can fill cartons.

So, we can write -

Machine 1's unit rate = 25

Machine 2's unit rate = 22

It is easily visible that Machine 1 fills cartons faster and fills 3 more cartons per minute than machine 2.

Therefore,

Machine 1's unit rate = 25 and Machine 2's unit rate = 22. Machine 1 fills cartons faster and fills 3 more cartons per minute than machine 2.

To find slope on the graph you use rise/run like #1 you go up 3 and across 2 so it’s 3/2 and positive because the line is going up if it were going going down it’s a negative slope…now to find it with the formula it says it right there y2-y1 over x2-x1 for example 14-10 over -7-8 and simplify if you can…on the table you will do the same as you did with the formula on #15 you will use the formula like this 2-5 over -2+3 because we all know when you subtract a negative with a negative you’re basically adding them together

Given that,

Wyatt invested $1,600 in an account paying an interest rate of 52% compounded annually.

Wyatt amount after 17 years is computed as,

                   [tex]Amount=1600*(1+\frac{52}{100} )^{17}\\\\Amount=\$ 1974517.5[/tex]    

Joshua invested $1,600 in an account paying an interest rate of 47%

compounded quarterly.    

Joshua amount after 17 years is computed as,

             [tex]Amount=1600*(1+\frac{47}{100} )^{17}\\\\Amount=\$ 1118187.6[/tex]
