please help me with this question

Answer:1.) I chose coin A and B

2.) Coin: B Value: $40 Annual rate: %5

Coin: A Value: $25 Annual rate: %7

3.) Coin: A P: 25 R: 1.07 Function: v = 25(1.07)^t

Coin: B P: 40 R: 1.05 Function: v = 40(1.05)^t

4.) Base: 1+r Initial: P Exponent: t

If R increased, then P would also increase because you must distribute, and you would be distributing R into P there for if R changes then so would P.

5.) Coin A: Initial value: $25 10 years: $25.70 20 Years: $26.40 30 years: $27.10 60 years: $29.20

Coin B: Initial value: $40 10 years: $40.50 20 years: $41 30 years: $41.50 60 years: $43

Coin C: Initial value: $60 10 years: $60.40 20 years: $60.80 30 years: $61.50 60 years: $62.40

6.) Coin A because the value goes up the most and I probably wouldn't be able to keep the coin for more than 60 years because I would lose it.

Step-by-step explanation:

i did it

I also chose coin A and coin B. You can choose any two coins you want, but the answers would turn out different so I recommend using A and B.

Answer:

2.      

Coin: A                     Current value: $25                     Appriciation rate: 7%

Coin: B                     Current value: $25                     Appriciation rate: 5%

3.

Coin: A               P: 25                  R: 0.07                 V(t) = 25(1+0.07)^t

Coin: B               P: 40                  R: 0.05                 V(t) = 40(1+0.05)^t

4.a

Base: 1+R

Constant or initial value: P

Exponent: T

4.b

No, the initial value would not increase, although, by changing the rate would increase the growth.

5.

Value:          25                            

10 years:      V(t) = 25(1.07)^10   -   $49.18

See explaination

Step-by-step explanation:

5.

So when the value is 25, we use the formula from question 3 ( V(t) = 25(1.07)^10 ) and solve

Continue to use the same formula to answer the other numbers of years, only change the exponent, ^10, to the number of years.

For example:  20 years = ^20                 30 years = ^30 and so on.

Also, this is the correct answer to number 5. I got an A on this assignment

GURL MY MATH TEACHER GAVE ME THE SAME SHEET A MONTH AGOO

YASS

1.) x is less than or equal to 3

2.) x greater than or equal to 2

3.) x < -1

4.)  x greater than or equal to 3

5.) x>2

6.)  x greater than or equal to 1

Answer:

yes because you got to tink about measuring stuff if you measure 1/4 it would be less than if you measure 3/4 because its closer to 4/4 whcich equals 1 so yes it is less than 3/4

Answer:

  43

Step-by-step explanation:

x° is common to both the smaller and the larger triangle, which means the sum of the two other angles will be the same in the two triangles:

  76° +49° = y° +81°

  124° -81° = y° = 43° . . . . . subtract 81°

Answer:

x = - 1

Step-by-step explanation:

Given

[tex]\frac{2}{5}[/tex] (x - 4) = 2x ( multiply both sides by 5 to clear the fraction )

2(x - 4) = 10x

2x - 8 = 10x ( subtract 2x from both sides )

- 8 = 8x ( divide both sides by 8 )

- 1 = x

Answer:

a) 5/18 hour

a) 3 3/5 tasks

Step-by-step explanation:

A robot can complete 3tasks in five sixth hour. Each task takes the same amount of time.

a. How long does it take the robot to complete one​ task?

3 tasks => 5/6 hour

1 task => x

3x = 1 × 5/6 hour

x = 5/6 ÷ 3

x = 5/6 × 1/3

x => 5/18 hour

b. How many tasks can the robot complete in one​ hour?

5/6 hour = 3 tasks

1 hour =>x tasks

5/6x = 1 × 3

x = 3 ÷ 5/6

x = 3 × 6/5

x = 18/5

x = 3 3/5 tasks

Answer:

A. 9 Desserts

Step-by-step explanation:

We can make the equation 2/3x = 6 to find the answer

2/3x = 6 we need to isolate x so we divide by 2/3 on both sides

2/3 / 2/3 = 1 and 6 / 2/3

we divide 6 by 2/3 like 6/1 * 3/2 = 9

x = 9

Answer:

Step-by-step explanation:

The required amount of flour will be 12 cups of flour in the recipe.

The ratio is defined as a relationship between two quantities, it is expressed as one divided by the other.

A recipe requires for 2 parts sugar to 3 parts flour. 8 cups of sugar are used which is given in the question.  

Let the number of cups of flour would be x,

According to the given question, the required ratio would be as

2 parts sugar : 3 parts flour = 8 cups of sugar : x cups of flour

2 / 3 = 8 / x

2x  = 24

x = 24/ 2

Apply the division operation,

x = 12

Therefore, the required amount of flour will be 12 cups of flour in the recipe.

Answer:

Yes, this is a function, because for every output there is one input!

Step-by-step explanation:

Answer:

length = 18 cm & width= 13 cm

Step-by-step explanation:

w+w+5+w+w+5=62

4w+10=62

4w=52

w=13

w+5=13+5 = 18 cm

Answer:

Check the explanation.

Step-by-step explanation:

As the graph of a linear function f passes through the point (-2,-10) and has a slope of 5/2.

As the slop-intercept form is given by:

[tex]y = mx+b[/tex]

where m is the slope and b is the y-intercept.

substituting the values (-2, -10) and m = 5/2 in the slop-intercept form to determine y-intercept.

[tex]y = mx+b[/tex]

[tex]-10=\frac{5}{2}\left(-2\right)+b[/tex]

[tex]-\frac{5}{2}\cdot \:2+b=-10[/tex]

[tex]-5+b=-10[/tex]

[tex]-5+b+5=-10+5[/tex]

[tex]b=-5[/tex]

And the equation of the line in the slope-intercept form will be:

[tex]y = mx+b[/tex]

putting b = -5 and slope = m = 5/2

[tex]y = mx+b[/tex]

[tex]y=\frac{5}{2}x+\left(-5\right)[/tex]

[tex]y=\frac{5}{2}x-5[/tex]

Determining the zero of function.

As we know that the real zero of a function is the x‐intercept(s) of the graph of the function.

so let us determine the value of x (zero of function) by setting y = 0.

[tex]0=\frac{5}{2}x-5[/tex]

[tex]\frac{5}{2}x-5=0[/tex]

[tex]\frac{5}{2}x=5[/tex]

[tex]5x=10[/tex]

[tex]x=2[/tex]

Therefore, the zeros of the function will be:

There are no errors.

Step-by-step explanation:

Answer:

Each students provides 13 pounds of meal

Step-by-step explanation:

Total students in Ms. Lee class = 220

Total pounds of food collected = 2,860

how many meals did each student provide?

Meals provided by each student = Total pounds of food collected / total number of students

= 2,860 / 220

= 13 pounds

Each students provides 13 pounds of meal

Note: 1.2 pounds of food equals one meal

1.2 pounds : 1 meal = 13 pounds : x meals

1.2/1 = 13/x

1.2 * x = 1 * 13

1.2x = 13

x = 13 / 1.2

= 10.83 meals

Approximately 11 meals to the nearest number

Note:1 kilogram is 2.2 pounds

1 kg : 2.2 pounds = x kg : 13 pounds

1/2.2 = x / 13

1 * 13 = 2.2 * x

13 = 2.2x

x = 13/2.2

= 5.91 kilogram

Approximately x = 6 kilograms

Answer:

7y = 4 or y = (4/7)

Horizontal line

Step-by-step explanation:

Plug the given variable values in.

0x + 7y = 4

Anything times 0 is 0. In addition, 0 doesn't need to be written.

7y = 4

I'm not sure if your teacher wants y to be separated from a coefficient that isn't 1. If so, y = (4/7).

This would be a horizontal line because y will always equal 4/7 on the graph, which would make a horizontal line parallel to the x axis at the value 4/7 along the y axis.
