Hal is asked to write an exponential function to represent the value of a $10,000 investment decreasing at 2% annually. What multiplicative rate of change should Hal use in his function?

0.02
0.98
1.02
1.98

Answers

Answer 1

Answer

The multiplicative rate of change that should be in Hal’s function = 49/50=0.98

=9.8×10⁻¹

Explanation

The investment of $10,000 decreases by 2% every year. So the following year is usually (100 - 2)=98% of the previous year. This is a geometric progression.

In this case the first term = 10000

The second term = 98% × 10000 = 9800.

The common ratio = 9800/10000=49/50

The multiplicative rate of change that should be in Hal’s function = 49/50=0.98.

The equation of the exponential rate would be;

10,000ₓ0.98ⁿ.

where n is the number years.

Hope his helps! ;)

What is 11d - 88. In algebraic expressions

Answers

Simplifying
11d + -88 = 0

Reorder the terms:
-88 + 11d = 0

Solving
-88 + 11d = 0

Solving for variable 'd'.

Move all terms containing d to the left, all other terms to the right.

Add '88' to each side of the equation.
-88 + 88 + 11d = 0 + 88

Combine like terms: -88 + 88 = 0
0 + 11d = 0 + 88
11d = 0 + 88

Combine like terms: 0 + 88 = 88
11d = 88

Divide each side by '11'.
d = 8

Simplifying
d = 8

Answer:

B) -1/2

C) {30, 150}

Step-by-step explanation:

Question 3)

We can see that the angle equals 210* which equals 7pi/6 (in radians)

The coordinates would be [tex](\frac{-\sqrt{3} }{2}, \frac{-1}{2})[/tex]

Since the problem is asking for sinθ, we will use -1/2 (the y-coordinate)

So the answer is B) -1/2..

Question 4)

If the criteria of the answer is that it must be between 0 < θ < 360 and it must have a y-value of 1/2 in its coordinate (sinθ = 1/2), then we will choose angles that meet this criteria. When we look at the unit circle (see the attached) we can see that only the angles of 30* and 150* match this answer, so our answer is c.

you guys help me out with these problems if you know how to do them?

Answers

I’ll explain how to graph them since there are quite a few problems. :)

The easiest way to graph is to first put down the y-axis, which is the end number on the end of the equation. For example, on the first problem the y-intercept is 5, so for this point you would just plot down (0,5).

Next you would just plot down points that follow the slope, which is the first number in the equation, and in the first problem it is 1/2.
The top number determines if you go up and down the bottom number determines where you go right. *only when the slope is negative will you go down for the top part of the slope*
For example, in the first problem you would start plotting from where you put your y-axis and go 1 up and 2 down to plot your next point. You would follow this trend another time or two until you can make your line.

Which of the equations below have one solution? Select all that apply. 8x–3x+5=5x–2 9=3(5x–2) 6x–(3x+8)=16 9x+4–x=4(2x+1)

Answers

Answer:

The equations that have one solution are 9=3(5x–2) and 6x–(3x+8)=16

Step-by-step explanation:

To determine which equations have one solution, we will determine the solution(s) to all the equations (that is, find the value of the unknown, x).

1. 8x–3x+5=5x–2

This becomes

5x+5=5x-2

Subtract 5x from both sides

5x-5x+5 = 5x-5x-2

0+5 = 0-2

This equation has no solution

2. 9=3(5x–2)

First, open the bracket by distributing 3

∴ 9 = 15x - 6

Then, add 6 to both sides

9+6 = 15x -6 +6

15 = 15x

Divide both sides by 15

15/15 = 15x/15

1 = x

∴ x = 1

This has one solution.

3. 6x–(3x+8)=16

Open the bracket by distributing –1

6x -3x -8 = 16

3x - 8 = 16

Add 8 to both sides

3x -8 +8 = 16 + 8

3x = 24

Divide both sides by 3

3x/3 = 24/3

x = 8

This has one solution.

4. 9x+4–x=4(2x+1)

This becomes

9x -x +4 = 4(2x+1)

Then, 8x +4 = 4(2x+1)

Open the bracket by distributing 4

8x +4 = 8x +4

This is true for any value of x.

Hence, the equations that have one solution are 9=3(5x–2) and 6x–(3x+8)=16.

(6x-4) + (3x+4) = 180
