The y-intercept of any function is the value of the function when x = 0.

The y-intercept of f(x) is f(0) = 4(0) - 1. This is equal to -1.
The y-intercept of g(x) is g(0), which we can see from the graph is 2.
The y-intercept of h(x) is h(0), which is cos(0 + 2pi). This is equal to 1.

Therefore, g(x) has the greatest y-intercept.

The value of a collector’s item is expected to increase exponentially each year. The item is purchased for $500. After 2 years,

Anika [276]

Answer:

Option 2 is correct.

Step-by-step explanation:

Actual price = $500

After 2 years the worth of item is increased to = $551.25

We need to find the equation that represents y, the value of the item after x years.

According to given information the equation can be of form

$y=500(r)^x$

where r represents the growth and x represents the number of yeras.

We need to find the value of r that represents the growth

The value of y = 551.25, and value of x = 2

Putting values and solving:

$y=500(r)^x\\551.25 = 500(r)^2\\551.25/500 =(r)^2\\1.1025 = (r)^2\\Taking square root on both sides\\\\\sqrt{1.1025}=\sqrt{(r)^2}\\ => (r) = 1.05\\$

Putting value of r in the equation

$y=500(r)^x$

$y=500(1.05)^x$

So Option 2 is correct.

a painting including the frame measures 71 cm by 75 cm How many centimeters of framing were needed to frame the painting?

Step2247 [10]

It depends on what is the width of framing and do we want to place it on painting or not but basically it is the circuit

Circuit = 2*71cm + 2*75cm=2*(71cm+75cm)=2*146cm=292cm

Answer:. U need 292cm of framing (at least).

Which expressions are equivalent when y = 2 and y = 5? 2 y minus 1 and 3 y minus 5 + y 5 y + 4 and 7 y + 4 minus 2 y y + 7 and y

noname [10]

Answer:

Option b

Explanation:

The question is shown in the attached image

To answer this question, we will simply substitute in the given expressions with the values y=2 and y=5

The correct option will be the one having equal vales in both cases

1. Option a:

At y = 2:

2y - 1 = 2(2) - 1 = 3

3y - 5 + y = 3(2) - 5 + 2 = 3

At y = 5:

2y - 1 = 2(5) - 1 = 10

3y - 5 + y = 3(5) - 5 + 5 = 15

This option is incorrect, since both expressions are not equal at y = 5

2. Option b:

At y = 2:

5y + 4 = 5(2) + 4 = 14

7y + 4 - 2y = 7(2) + 4 - 2(2) = 14

At y = 5:

5y + 4 = 5(5) + 4 = 29

7y + 4 - 2y = 7(5) + 4 - 2(5) = 29

This option is correct, since both expressions are equal at the two vales of y

3. Option c:

At y = 2:

y + 7 = 2 + 7 = 9

y + 2 + y = 2 + 2 + 2 = 6

At y = 5:

y + 7 = 5 + 7 = 12

y + 2 + y = 5 + 2 + 2 = 12

This option is incorrect, since both expressions are not equal at y = 2

4. Option d:

At y = 2:

3y - 4 = 3(2) - 4 = 2

3y - 2 + y = 3(2) - 2 + 2 = 6

At y = 5:

3y - 4 = 3(5) - 4 = 11

3y - 2 + y = 3(5) - 2 + 5 = 18

This option is incorrect, since both expressions are neither equal at y = 2 or y = 5

Hope this helps :)

12 21 23 32 34 43 what is the next numbers

poizon [28]

after each number you had 11

so when you subtract

32-12 = 11

now add this 11 to 43

11+43 = 54

so the next numbers are 45 and 54

I hope that's help ! Please let me know if you have questions !
