A new laptop is on sale for $550 dollars. To pay for it you place it on your credit card which charges 12% percent interest each month

Answers

The answer would be $75 each month.

The interest amount charged on a new laptop is on sale for $550 dollars is $66.

Given that, a new laptop is on sale for $550 dollars.

What is percentage?

Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".

Now, 12% of 550

= 12/100 ×550

= 0.12 ×550

= $66

So, interest is $66

Therefore, the interest amount charged on a new laptop is on sale for $550 dollars is $66.

Ten deer were introduced into a protected preserve. Their expected population doubles each year. Which function represents the same relationship?

Answers

Answer:

y(t)= 10 (2)^t

Step-by-step explanation:

If t is the number of years given then the expected number can be found by

y(t)= 10 (2)^t

where t takes the value 0,1,2,3, and so on.

Putting t= 0

y(t)= 10 (2)^t

y(0)= 10 (2)^0

y(0)= 10   For the start the number of deer are 10.

Putting t= 1

y(t)= 10 (2)^t

y(1)= 10 (2)^1

y(1)= 20    After 1 year it has doubled to 20

Putting t= 2

y(t)= 10 (2)^t

y(2)= 10 (2)^2

y(2)= 40      After 2 years it has again doubled to 40

Putting t= 3

y(t)= 10 (2)^t

y(3)= 10 (2)^3

y(3)= 80   After 3 years it has again doubled to 80

Answer:

k = 5.25

Step-by-step explanation:

Given y varies directly with x then the equation relating them is

y = kx ← k is the constant of proportionality

To find k use the condition y = 84 and x = 16 , then

84 = 16k ( divide both sides by 16 )

5.25 = k

In a hydroelectricity production, water falls from a dam into a turbine wheel 49 m below. What is the velocity of water at the turbine?

A) 0 m/s
B) 15.5 m/s
C) 31 m/s
D) 46.5 m/s

Answers

Answer:

C: 31 m/s

Step-by-step explanation:

It falls from a dam.

Thus;

Initial velocity; u = 0 m/s

Height; h = 49 m

Acceleration due to gravity is 9.8 m/s²

To solve for the final velocity this, we will use Newton's third equation of motion;

v² = u² + 2gh

v² = 0² + 2(9.8 × 49)

v = √960.5

v ≈ 31 m/s
