Mathematics
1 answer:
Rom4ik [11]3 years ago
6 0

Answer:

1. Yes

2. Yes

3. No

6. Yes

7. No

See descriptions and reasons why below.

Step-by-step explanation:

A function is a rule that assigns exactly one output to every input. This means that no input value (x value) can repeat and have different output values *y values).

1. Output values repeat for different input values. This is a function still.

2. Quadratic equations for a U shape graph and do not have repeating inputs so it is still a function.

3. A circle is not a function. It has repeating inputs. Draw a vertical line down through the circle. It intersects at more than one point. Not a function.

4. Not readable in the picture.

5. Not readable in the picture.

6. Yes it is a function. Draw a vertical line and it intersects only once. Therefore, it has no repeating inputs.

7. Not a function. The x values or inputs repeat 25 and 36 with different output values each time.

Becky invests £5000 for 2 years in a bank account.
Arte-miy333 [17]

Answer:

£300

Step-by-step explanation:

We apply the formula for Simple Interest:

I = \frac{P * R * T}{100}

where P = Principal

R = Rate of interest

T = Time elapsed (in years)

We are given that P = £5000, R = 3%, T = 2 years

The interest after 2 years will be:

I = \frac{5000 * 3 * 2}{100} \\\\\\I = \frac{30000}{100}

I = £300

The interest Becky will get after 2 years will be £300.
