What does the y-intercept mean? What does the x-intercept mean? Explain what each intercept means and then Identify the x-interc

irinina [24]

x intercept = where the function crosses the x axis (x,0)

y intercept = where the function crosses the y-axis (0,y)

A. y=7/2x-2

x intercept , replace y by 0 and solve for x:

0 =7/2x-2

2= 7/2 x

2 / (7/2) = x

x= 4/7

y-intercept, replace x by 0 and solve for y

y= 7/2x-2

y= 7/2 (0) -2

y=-2

x-intercept:

x=-3

y-intercept

0=-3

It doesn't have a y-intercept.

A circular swimming pool has a diameter of the 26 feet. What is the area of the swimming pool? Use 3.14 to approximate for π . E

inn [45]

So the equation for the area of a circle is $A=3.14(r^2)$

First to find the radius, you would need to divide the diameter, 26, by half, which in this case its 13.

Replace the r variable with 13 and solve:

$A=3.14(13^2)$

$A=3.14(169)$

$A=530.7$

Find the tenth term in the sequence

attashe74 [19]

Answer: The tenth term in the sequence is 512.

Step-by-step explanation:

Since we have given that

$a_n=2^{n-1}$

We need to find the tenth term:

It means n = 10

So, it becomes

$a_{10}=2^{10-1}\\\\a_{10}=2^9\\\\a_{10}=2\times 2\times 2\times 2\times 2\times 2\times 2\times 2\times 2\\\\a_{10}=512$

Hence, the tenth term in the sequence is 512.

A plumber charges an initial fee of $200 plus and hourly fee of $50. Mrs. Coombs paid the plumber $ 450. How many hours did the

nikitadnepr [17]

Answer:

5 hours

Step-by-step explanation:

The total cost is the fee plus the hours* hourly cost

450 = 200+50*h where h is the hours

Subtract 200 from each side

450-200 = 200-200 +50h

250 = 50h

Divide each side by 50

250/50 = 50h/50

5 = h

5 hours
