Answer:

  26. B(t) = 500·1.075^t; B(6) ≈ $772

  27. G(t) = 70·0.72^t; G(3) ≈ 26 g

Step-by-step explanation:

The equation with the plus sign is used when the value is increasing. The minus sign is used when the value is decreasing. The 'a' in each equation is the initial value.

__

26. B(t) = 500·1.075^t

  B(6) = 771.65

The balance after 6 years is about $772.

__

27. G(t) = 70·0.72^t

  G(3) = 26.127

About 26 grams are left after 3 days.

. Find f(3) for the following function


[tex]f(x)=3(2)^x+6[/tex]

a.f(3) = 222
b.f(3) = 9
c.f(3) = 24
d.f(3) = 30

Answers

Answer:

[tex]\boxed {\boxed {\sf D. \ f(3)= 30}}[/tex]

Step-by-step explanation:

We are given the function:

[tex]f(x)= 3(2)^x+6[/tex]

We want to find f(3), so we must substitute 3 in for x.

[tex]f(3)= 3(2)^3+6[/tex]

Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction.

Solve the exponent first.

2³= 2*2*2= 4*2= 8

[tex]f(3)= 3(8)+6[/tex]

Multiply 8 and 3.

[tex]f(3)= 24+6[/tex]

Add.

[tex]f(3)=30[/tex]

For the function given, f(3) is 30.

Answers

Answer:

This is an identity or infinite solutions

Step-by-step explanation:

10x - 12y = 22

5x - 6y = 11

-2(5x - 6y = 11 )

-10x + 12y = -22

10x - 12y = 22

0=0

Identity solution

Answer:

2(5x - 6y = 11)= 10x - 12y = 22 so they are the same equation

Which of the following expressions are equivalent to -4/7 - 8/9 + 4/7 + 9/8?

Answers

Answer:

C and D

Step-by-step explanation:

I'm too braindead to explain this, read comments

Answer:

-2 1/72

Step-by-step explanation:

Start by combining -4/7 and 4/7 to make 0, shortening your equation. Then continue by making the fractions remaining, 8/9 and -9/8, have a common denominator. To do this, we multiply -8/9 by 8, and -9/8 by 9. Then, we have -64/72 and -81/72. Then, we can combine the numerators of the fractions, as they have common denominators, and we get the fraction -145/72. We can then simplify this to -2 1/72.

Find the number of sides of a regular polygon if one interior angle is 120 degrees A3 B4 C5 D6​

Answers

Answer:

n = 6

Step-by-step explanation

Number of sides = 360/Measure of exterior

Measure of exterior = 180 - interior angle

Exterior angle = 180 - 120

Exterior angle  = 60 degrees

Substitute into the formula

number of sides = 360/60

number of sides = 6

Hence the number of sides required is 6

Use the figure to complete the proportion.

Samantha bought a refrigerator that is 3 1/2 feet wide, 5 1/2 feet tall, and 2 1/2 feet deep. How much space will the new refrigerator occupy?

Answers

Answer:

48.125 ft³

Step-by-step explanation:

The space occupied by the new generator is the product of it's dimension:

The space occupied = Length * width * height

Space occupied = 3 1/2 * 5 1/2 * 2 1/2

Space occupied = 7/2 * 11/2 * 5/2

Space occupied = (7*11*5) / (2*2*2) = 385 / 8

Space occupied = 48.125 ft³

Which expression is the factorization of x^2+10x+21?

Answers

Answer:

To factor a trinomial in the form Ax^2 + Bx + C when the A = 1.  You need to find the factors of C that when added or subtracted will give you B.  

Factors of 21 are either 1,21 or 3,7.  Since +3 and +7 will give you 10 then those will be the two factors you will use.

Factoring x^2+10x+21 will give you (x+3)(x+7)

Step-by-step explanation:

Answer:

25. Multi-A carpenter is making a tray to fit between two circular pillars in the shape of the shaded area as shown. She is using a jigsaw to cut along the edge of the tray. What is the length of the cut encompassing the tray? Round to the nearest half foot.

Answers

Answer:

21.5 feet.

Step-by-step explanation:

Calculate the length of a curved edge.

s =  

m

360

  · 2πr Use the formula for arc length.

=  

90

360

  · 2π(3) Substitute 3 for r and 90 for m.

= 1.5π Simplify.

Let t be the length of the cut encompassing the tray.

t = 2 · 1.5π + 2 · 6

= 3π + 12 Simplify.

≈ 21.5 ft Use a calculator to evaluate. Then round your answer to the nearest half foot.

The length of the cut encompassing the tray is 21.5 feet.

How many hours did Jerry play with his 333 friends today?

Answers

Answer:

8 1/8 hours

Step-by-step explanation:

Jerry played with 3 friends today, all at different times.

Tommy = 1 7/8 hours

Nathan = 1 3/4 hours

Chris = 3 3/2 hours

How many hours did Jerry play with his 3 friends today?

Number of hours Jerry play with his 3 friends today = 1 7/8 + 1 3/4 + 3 3/2

= 15/8 + 7/4 + 9/2

= (15+14+36)/8

= 65/8

= 8 1/8 hours
