Answers

Answer:

The roots of a function are the x-intercepts. By definition, the y-coordinate of points lying on the x-axis is zero. Therefore, to find the roots of a quadratic function, we set f (x) = 0, and solve the equation, ax2 + bx + c = 0.

Taliyah plans to borrow $4500 from the bank to purchase a used vehicle. If she borrows the money at a rate of 4% simple interest for 2 years, what is the total amount she will have to pay back to the bank

Answers

Answer:

$4860

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 4%/100 = 0.04 per year,

then, solving our equation

I = 4500 × 0.04 × 2 = 360

I = $ 360.00

The simple interest accumulated

on a principal of $ 4,500.00

at a rate of 4% per year

for 2 years is $ 360.00.

Answer:

2250

Step-by-step explanation:

you times 4500 with 2 and get 9000. Then, you take the 9000 and divide it by 4 and get 2250.

The distance from the origin to the point (-27,36)

Answers

The distance from the origin to the point (-27,36) is 45

We are going to make use of  Pythagorean Theorem to determine the length of the hypotenuse of the right triangle:

Hence;

  (0,0) to (-27,0)

  (-27,0) to (-27,36)

Using this formula

c2 = a^2 + b^2

Let plug in the formula

c2 = (-27)^2 + (36)^2

c2=-729+1296

c2 = √2025

 c = 45

Inconclusion The distance from the origin to the point (-27,36) is 45.

Car repairs: Let be the event that a new car requires engine work under warranty and let be the event that the car requires transmission work under warranty. Suppose that ,P(E) = 0.10 , P(T) = 0.02 and P(E,T) = 0.01 .
(a) Find the probability that the car needs work on either the engine, the transmission, or both.
(b) Find the probability that the car needs no work on the engine.

Answers

Answer:

a) 0.11 =  11% probability that the car needs work on either the engine, the transmission, or both.

b) 0.9 = 90% probability that the car needs no work on the engine.

Step-by-step explanation:

P(E) = 0.10 , P(T) = 0.02 and P(E,T) = 0.01 .

This means that:

Only engine: 0.1 - 0.01 = 0.09

Only transmission: 0.02 - 0.01 = 0.01

Both engine and transmission: 0.01

(a) Find the probability that the car needs work on either the engine, the transmission, or both.

0.09 + 0.01 + 0.01 = 0.11

0.11 =  11% probability that the car needs work on either the engine, the transmission, or both.

(b) Find the probability that the car needs no work on the engine.

Probability of needing work on engine:

0.09 + 0.01 = 0.1

Not needing:

1 - 0.1 = 0.9

0.9 = 90% probability that the car needs no work on the engine.

Solid A is dilated using a scale factor of 2⁄5, resulting in Solid B. Solid B is also dilated using a scale factor of 2⁄5, resulting in Solid C. If the volume of Solid B is 72 km^3, what is the volume of Solid A and Solid C?

Answers

Answer:

28.8 and 180

Step-by-step explanation:

you just times B by 2/5 to get C and divide it by 2/5 to get A

C = (72)(2/5) = 28.8 km³

A = (72)/(2/5) = 180 km³

We know the answers make sense because A shrinks to get B and B shrinks to get C, and our answers match that.

Equation: 5 + 8x < 3(2x + 4)


• So let’s first distribute:

Multiply 3 by (2x + 4)

That will be 6x + 12.


Put into the question: 5 + 8x < 6x + 12


• Now we can move the numbers around and UNDO to solve for x.

I will move the coefficient first, so subtract 6x from both side, so that it is easier:

5 + 8x < 6x + 12
- 6x < - 6x

That will be: 5 + 2x < 12


Now we’ll subtract the 5 from both side:

5 + 2x < 12
- 5 < -5

That will left with: 2x < 7


Now we divide both side by 2 to left with x.

2x < 7
—- —-
2 2

Now that will be: x is less than 3.5

x < 3.5


Since the inequality is open, the dot is white, or not shaded.

And since x is less than 3.5, any number less than 3.5 is the answer, so A is the answer.

According to the 2006 Uniform Crime Report (UCR), the state of Delaware had a population of 853,476 and 5,817 violent crimes. Compute the violent crime rate per 100,000 persons and interpret your result.

Answers

Answer:

682

Step-by-step explanation:

Population = 853,476

Number of violent crimes = 5817

We are to get violent crime rate per 100000 persons and interpret the result obtained.

Now if population is 1

Crime = 5817/853476

If population is 100000,

Crime = 5817x100000/853476

= 681.56

= 682

We conclude that the violent crime rate is of 682 crimes per 100000
