What is the Y intercept in the equation Y equals 45X +65?

1 answer:

3 0

The typical form of the slope intercept equation would be:

Y = mX + B

Where b is the y intercept, thus in thus case the y intercept would be 65 = (0,65).

The price of a computer component is decreasing at a rate of 15% per year. State whether this decrease is linear or exponential

Margaret [11]

Answer:

Since the price is given by an exponential function, the decline in price is exponential.

The component will cost $36.8475 in three years.

Step-by-step explanation:

The equation for the price of a component has the following format:

$P(t) = P(0)(1-r)^{t}$

In which P(t) is the price after t years, P(0) is the initial price, and r is the rate that the price decreases.

Since the price is given by an exponential function, the decline in price is exponential.

The price of a computer component is decreasing at a rate of 15% per year.

This means that $r = 0.15$

Component costs $60 today

So P(0) = 60. Then

$P(t) = P(0)(1-r)^{t}$

$P(t) = 60(1-0.15)^{t}$

$P(t) = 60(0.85)^{t}$

What will it cost in three years?

This is P(3).

$P(t) = 60(0.85)^{t}$

$P(3) = 60(0.85)^{3} = 36.8475$

The component will cost $36.8475 in three years.

The number 40 can be written as the product of a prime factor like 40=2×2×2×5 . Write the number 100 as a product of its prime f

Vladimir79 [104]

Answer

The answer to your question is 2 x 2 x 5 x 5 or 2² 5²

Step-by-step explanation:

Process

1.- To find the prime factors of a number, we must divide the number by prime numbers like 2, 3, 5, 7, 11, etc. starting from the lowest number.

100 2

50 2

25 5

5 5

Then 100 = 2 x 2 x 5 x 5 or 2² 5²

5 0
