Answer:

1. not a function.

2. is a function.

3. is a function.

4. not a function.

5. is a function.

6. not a function.

7. not a function.

8. is a function.

9. not a function.

10. is a function.

11. not a function.

12. not a function.

Step-by-step explanation:

1. not a function because the same input goes to 2 different outputs. A function input cannot have 2 outputs.

2. is a function because each input only goes to one output.

3. is a function because each input only goes to one output.

4. not a function because the same input goes to 2 different outputs. A function input cannot have 2 outputs. It does not pass the vertical line test.

5. is a function because each input only goes to one output.

6. not a function because the same input goes to 2 different outputs. A function input cannot have 2 outputs.

7. not a function because the same input goes to 2 different outputs. A function input cannot have 2 outputs.

8. is a function because each input only goes to one output. It also passes the vertical line test.

9. not a function because the same input goes to 2 different outputs. A function input cannot have 2 outputs. It also did not pass the vertical line test.

10. is a function because each input only goes to one output. It also passes the vertical line test.

11. not a function because the same input goes to 2 different outputs. A function input cannot have 2 outputs. It also did not pass the vertical line test.

12. not a function because the same input goes to 2 different outputs. A function input cannot have 2 outputs. It also did not pass the vertical line test.

Correct Question:

Explain how you know that 88 is a solution to the equation 1/8x =11 by completing the sentences:

The word "solution" means . . .

88 is a solution to 1/8x=11 because . . .

Answer/Step-by-step explanation:

✔️The word solution means the value of the unknown variable, x. This means, when the value of x is substituted into the equation, the equation becomes balance as the value on the left equals the value on the right.

✔️88 is a solution to ⅛x = 11 because:

if we substitute x for 88 into the equation, both sides would be equal.

Thus:

⅛×88 = 11

11 = 11

Answer:

$Area = 129.5m^2$

$Perimeter = 48m$

Step-by-step explanation:

Given

See attachment

Required

Determine the area and the perimeter of the garden

Calculating Area

First, we calculate the $area\ of\ the\ rectangle$

$A_1 = L * B$

Where:

$L = 20-(3.5 +3.5)$

$B = 7$

So:

$A_1 = (20 - (3.5 + 3.5)) * 7$

$A_1 = (20 - 7) * 7$

$A_1 = 13 * 7$

$A_1 = 91$

Next, we calculate the area of the two semi-circles.

Two semi-circles = One Circle

So:

$A_2 = \pi r^2$

Where

$r = \frac{7}{2}$

$A_2 = \frac{22}{7} * (\frac{7}{2})^2$

$A_2 = \frac{22}{7} * \frac{49}{4}$

$A_2 = \frac{22}{1} * \frac{7}{4}$

$A_2 = \frac{22*7}{4}$

$A_2 = \frac{154}{4}$

$A_2 = 38.5$

Area of the garden is

$Area = A_1 + A_2$

$Area = 91 + 38.5$

$Area = 129.5m^2$

Calculating Perimeter

First, we calculate the perimeter of the rectangle

But in this case, we only consider the length because the widths have been covered by the semicircles

$P_1 = 2 * L$

Where:

$L = 20-(3.5 +3.5)$

So:

$P_1 =2 * (20-(3.5 +3.5))$

$P_1 =2 * (20-7)$

$P_1 =2 * 13$

$P_1 =26$

Next, we calculate the perimeter of the two semi-circles.

Two semi-circles = One Circle

So:

$P_2 = 2\pi r$

Where

$r = \frac{7}{2}$

$P_2 = 2 * \frac{22}{7} * \frac{7}{2}$

$P_2 = \frac{2 * 22 * 7}{7 * 2}$

$P_2 = \frac{308}{14}$

$P_2 = 22$

Perimeter of the garden is

$Perimeter = P_1 + P_2$

$Perimeter = 26 + 22$

$Perimeter = 48m$

An element with mass 970 grams decays by 27.7% per minute. How much of the element is remaining after 13 minutes, to the nearest

Mnenie [13.5K]

Basically, 27.7% of 970 is 268.69 grams, if 13 minutes so i’m pretty sure it’s 268.69 X 13 = 3492.97, it cannot be deduced from 970 unless it became −2522.97, is that the answer ur looking for?
