what’s the slope and y intercept of the loire that is perpendicular to y=-2x-5 and passes through the point (-3,-6)
Doss [256]

Answer:

slope: ½

y-intercept: -4½

Step-by-step explanation:

Slope: negative reciprocal of -2

-1/-2 = 1/2

y = ½x + c

-6 = ½(-3) + c

-6 = -3/2 + c

c = -6 + 3/2

c = -9/2 = -4½

Explain how you can approximate a cube root when the cube is not a perfect cube.
jenyasd209 [6]

Answer:

See below.

Step-by-step explanation:

It would take a long time to explain . There is a good method called Newton's method which involves graphs of the type

y = x^3 - n and applying calculus to produce cycles of approximation  until you'll get close to the required cubic root.

You'll find it on online videos.

Computer towers purchased for $30900 depreciates at a constant rate of 12.6% per year. Write the function that models the value
Paha777 [63]

Answer: the computer towers will be worth $10521 after 8 years

Step-by-step explanation:

We would apply the formula for exponential decay which is expressed as

A = P(1 - r)^t

Where

A represents the value of the computer towers after t years.

t represents the number of years.

P represents the initial value of the computer towers.

r represents rate of decay.

From the information given,

P = $30900

r = 12.6% = 12.6/100 = 0.126

Therefore, the function that models the value of the computer towers after (t)years from now is

A = 30900(1 - 0.126)^t

A = 30900(0.874)^t

Therefore, when t = 8 years, then

A = 30900(0.874)^8

A = $10521
