Opens up or down, Vertex: (-10, -1), Passes through: (-8, -5)

Answers

Answer:

opens down

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

Here (h, k) - (- 10, - 1 ) , then

y = a(x + 10)² - 1

To find a substitute (- 8, - 5) into the equation

- 5 = a(- 8 + 10)² - 1 ( add 1 to both sides )

- 4 = a(2)² = 4a ( divide both sides by 4 )

- 1 = a

y = - (x - 10)² - 1 ← equation in vertex form

To determine if it opens up/ down consider the value of a

• If a > 0 then curve opens up

• If a < 0 then curve opens down

Here a = - 1 < 0 then curve opens down

How much money will need to be paid back to the bank for this loan?

Answers

Answer:

the money required to pay back to the bank for the loan is $7,002

Step-by-step explanation:

The computation of the money required to pay back to the bank for the loan is given below:

= Principal × (1 + rate of interest)^number of years

= $4,000 × (1 + 0.0725)^8

= $4,000 × 1.0725^8

= $7,002

Hence, the money required to pay back to the bank for the loan is $7,002

Ms.Maxwell bought a purse with 1/4 of her money. The purse cost $37.00. How much money did Ms.Maxwell have left after she bought the purse?

Answers

Answer:

the money left after purchasing the purse is $111

Step-by-step explanation:

The computation of the money left after purchasing the purse is given below:

Since in the question it is mentioned that she bought a purchase with one-fourth of money

And, the purse cost is $37

So the amount left would be

= $37 × (3 ÷ 4) ÷ (1 ÷ 4)

= $37 × 0.75 ÷ 0.25

= $111

Hence, the money left after purchasing the purse is $111

Simon makes a model of a boat, using a scale of 1 : 30

If the model has a height of 40 cm, find the height of the real boat.

Give your answer in metres.

Answers

Answer: 12 metres

Step-by-step explanation:

The scale factor used for the model is 1 : 30.

This means that for any 1cm on the model, the real boat would be 30 cm.

If the height is 40 cm on the model, the real boat will be 30 times that:

= 40 * 30

= 1,200 cm

A metre is equivalent to 100cm.

1,200 cm would therefore be:

= 1,200/100

= 12 metres
