Step-by-step explanation:

Answer:

f(n) = 0.2n + 4.8

4.8

Step-by-step explanation:

Given the explicit formula :

an = 5 +0.2(n - 1)

Expressing an in function form f(n):

f(n) = 5 + 0.2(n - 1)

f(n) = 5 + 0.2n - 0.2

f(n) = 5 - 0.2 + 0.2n

f(n) = 0.2n + 4.8

The y - intercept :

Set n = 0

f(n) = 0.2n + 4.8

f(0) = 0.2(0) + 4.8

= 0 + 4.8

= 4.8

y intercept = 4.8

Step-by-step explanation:

Answer:

subtract 40 from both sides

Answer:

You subtract 40 which will equal -6 and now you divide  -6/4n and the answer is n=-1.5

Step-by-step explanation:

Answer:

m∠T = 72°

m∠U = 54°

Step-by-step explanation:

Property of an isosceles triangle,

Opposite angles of two equal sides of an isosceles triangle are equal in measure.

By this property, in the given triangle STU,

Since, ST ≅ TU,

m∠S = m∠U = 54°

Since, sum of interior angles of a triangle is 180°

m∠T + m∠S + m∠U = 180°

m∠T + 54° + 54° = 180°

m∠T = 180° - 108°

m∠T = 72°

true

Answer:

y = 2

Step-by-step explanation:

14-4y=y+4

5y = 10

y = 2

Answer:

2

y =2

Answer: 11.59 months

Step-by-step explanation:

You need to divide 339.12 by 29.26. Then you should check your answer by multiplying 11.59 by 29.26. Which should get you 339.1234. When you sound that you get 339.12. Hope this helps!!

Answer:

1- The student spent 48 minutes and 45 seconds playing basketball.

2- The student spent 33 minutes and 45 seconds playing soccer.

Step-by-step explanation:

1- If during a week the student exercised for 3 hours at school, and for 1/4 hour at home, it could be said that the student exercised for a total of 195 minutes (60 x 3 + 60/4) . Now, if I exercise 1/4 of that time playing basketball, the student spent 48 minutes and 45 seconds playing that sport (195/4).

2- If during a week the student exercised for 2 hours at school, and for 1/4 hour at home, it could be said that the student exercised for a total of 135 minutes (60 x 2 + 60/4) . Now, if I exercise 1/4 of that time playing basketball, the student spent 33 minutes and 45 seconds playing soccer (135/4).

Answer:Yes she has enough

Step-by-step explanation:

Total ounces=11

1st recipe=6 ounces

2nd recipe=1/4 ounces

1 pound =16 ounces

= 1/4 pounds × 16 ounces/1 pound

= 4 ounces

First recipe + Second recipe

= 6 ounces + 4 ounces

= 10 ounces.

10 ounces of walnuts and Marni has 11

Answer:

Scale Factor: 2.5   Length of RS: 14.375

Step-by-step explanation:

Answer:

-3

Step-by-step explanation:

Answer:

Option (1)

Step-by-step explanation:

In a geometric series,

[tex]\sum_{n=0}^{\infty}ar^n=a+ar^1+ar^2+....[/tex]

Here r = [tex]\frac{a_n}{a_{n-1}}[/tex]

For |r| < 1, series will converge.

For |r| > 1, series will diverge.

Option (1)

Given geometric series is,

[tex]\frac{1}{2}+\frac{1}{4}+ \frac{1}{8}+ \frac{1}{16}.......[/tex]

Common ratio = [tex]\frac{\frac{1}{4}}{\frac{1}{2} }[/tex]

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

Since, [tex]\frac{1}{2}<1[/tex]

Series will converge.

Option (2)

[tex]\frac{1}{2}+1+2+4+......[/tex]

r = [tex]\frac{1}{\frac{1}{2}}=2[/tex]

Since, 2 > 1,

Series will diverge.

Option (3)

[tex]\frac{1}{2}+ \frac{3}{2}+ \frac{9}{2}+ \frac{27}{2}+......[/tex]

Common ratio 'r' = [tex]\frac{\frac{3}{2} }{\frac{1}{2} }=3[/tex]

Since, 3 > 1,

Series will diverge.

Option (4)

[tex]\frac{1}{2}+3+18+108+.....[/tex]

Common ratio 'r' = [tex]\frac{3}{\frac{1}{2}}=6[/tex]

Since, 6 > 1

Series will diverge.

Therefore, Option (1) will be the correct option.

Answer:

it takes 3 seconds for it to get the the maximum height

Step-by-step explanation:

well this is easy bc it is negative so we know it goes down, meaning the vertex will be at the top/highest point.

so all u gotta do is find the vertex which is x=-b/2a

now we gotta plug the numbers in and solve

h(x)=-3x^2+18x

x=-18/2(-3)=-18/-6=3

voilà there is the answer, 3 seconds

Answer:

The scale model giraffe is 5 inches tall.

Step-by-step explanation:

Since the artist sculpted the figure of the giraffe with a scale of 1 inch = 4 feet, and that the real giraffe that lives in the zoo is about 20 feet, to determine the size of the sculpted giraffe to scale it is necessary to perform the following calculation:

20/4 = X

5 = X

Thus, the scale sculpted giraffe that will be sold in the gift shop measures 5 inches.

Im not sure and im SO SORRY if its wrong

Step-by-step explanation:

Answer:

y = 17

Step-by-step explanation:

y = 4x + 5

since the x value is 3 you substitute it in

y = 4(3) +5

y = 12 +5

y = 17

Answer

14(1+3)

Explanation

The greatest common factor of 14 and 42 is 14.

Divide 14 and 42 each by 14.

14÷14=1

42÷14=3

So 14+42 factored is 14(1+3).

You can also check your answer.

1+3=4

14×4=56

-----

14+42=56

Answer:

29

Step-by-step explanation:

I am going to assume (y)2 = [tex]y^{2}[/tex] because you have the term 2y right after.

when y = -6

[tex](-6)^2+2(-6) + 5 = 36-12+5\\= 29[/tex]
