6 The interior angles of a triangle always sum to 180°. The measure of ZC is 8°
less than the measure of ZD. Find the values of x and y.

Answers

Answer:

m<D=67

m<C=59

Step-by-step explanation:

m<C=y-8

m<D=y

m<A=54

put all the angles together and equal to 180

(y-8)+(y)+(54)=180

now solve the equation

67=y

An initial population of 415

ducks increases at an annual

rate of 32%. Write an

exponential function to model

the duck population.

Answers

Answer:

The exponential function to model the duck population is:

f(n)=415*(1.32)^n, where:

x is the duck population

n is the number of years

Step-by-step explanation:

In order to calculate the duck population you can use the formula to calculate future value:

FV=PV*(1+r)^n

FV=future value

PV=present value

r=rate

n=number of periods of time

In this case, the present value is the initial population of 415 and the rate is 32%. You can replace these values on the formula and the exponential function to model the duck population would be:

f(n)=415*(1+0.32)^n

f(n)=415*(1.32)^n, where:

x is the duck population

n is the number of years

Mike is driving a Toyota Camry. He’s inflated his tire to the dealer-recommend level of 32 PSI. At what speed will Mike’s car start hydroplaning? With what tire pressure would his car start hydroplaning at 45 miles per hour? Use the formula v=10.35 square root p

Answers

Answer:

Part A

A speed of approximately 58.55 mph

Part B

A pressure of approximately 18.9 psi

Step-by-step explanation:

Part A

The parameter for the car are;

The tire pressure, p = 32 psi

The given equation determined for the speed, 'v', when a car will start hydroplaning is presented as follows;

v = 10.35·√p

Where;

v = The speed at which the car is moving when it will hydroplane in mpj

p = The pressure in the tire in psi

The speed at which hydro planning will start in Mike's car that has a tire pressure of 32 psi is therefore;

v = 10.35 × √(32 psi) ≈ 58.55 mph

The speed at which hydro planning will start in Mike's car that has a tire pressure of 32 psi, v ≈ 58.55 mph

Part B

When a car is moving at, v = 45 mph, we have;

v = 10.35·√p

∴ The pressure in the car tire, p = (v/10.35)²

∴ at p = 45 mph, we have;

p = (45 mph/10.35)² ≈ 18.9 psi

The tire pressure at which Mike's car start hydroplaning, p ≈ 18.9 psi
