Here, we want to write ratios in part to part and in part to whole ratio

For the part to part

Writing carrot to peas, we have;

For the parts to whole ratio, we have;

The price of gas = $2.85 per gallon

It was $1.36 cheaper than a year before.

So, the price before = 2.85 + 1.36 = $4.21

So, the percent of decrease = 1.36/4.21 = 0.323 = 32.3%

To find the result function,

First stretch it, multiplying it by the factor we want to stretch.

So f(x) = x²

Stretching the function by a factor of 2:

g(x) = 2* f(x)

g(x) = 2* x²

On the other hand, to translate a function 4 units upward, we need to sum it to the function, so the result function is:

g(x) = 2x² + 4

Given :

The total questions = 300

Time of starting = 5:00

At 6:30 the number of answered questions = 55

The time spent to answer 55 questions = 6:30 - 5:00 = 1:30 hours

Which is equal to : 1 hour and 30 minutes = 90 minutes

So, the rate of answering the questions =90/55 = 18/11 minute per question

So, for solving the 300 questions, the time will be :

So, 490 10/11 minutes = 8 hours and

The ratio of the corresponding sides are:

Substitute the given values from the diagram above:

We then solve the equation for x.

The length of FE is √286 units (in simplest radical form).

Home Liquidators marks up its merchandise 35% on cost, the company's equivalent markup on the selling price is 25.9%.

An equivalent value represents equality.

Equivalent values show that two paired mathematical expressions are equal.

The markup on the selling price can be derived by equating the markup on cost with the markup on the selling price as follows:

Markup on cost = 35%

Cost = 100%

Selling price = 135%

Markup on selling price = 25.9% (0.35/1.35 x 100)

Thus, we can describe Home Liquidators' markup on the selling price as equivalent to 25.9% or simply 26%.

When the outer diameter of the ball with ice on it is 24 cm then the outer surface area of ice changes at the rate of 1/90cm²/sec.

As given in the question,

Spherical ball is coated with uniform thickness.

Ice melts at the rate of 8ml/min

= (8/60)cm³/sec

Consider r as the  radius of given spherical ball

Diameter = 24cm

⇒Radius 'r' =12cm

Volume 'V' = (4/3)πr³

⇒ dV /dt = (4/3)π(3r²r')

⇒-(8/60) = (4/3)π(3 ×12²×r')

⇒r' =-(8/60)×(1/576π)

⇒r' = - 1/ 4320π

Rate at which change in surface area

A =4πr²

⇒A' = 4πrr'

⇒A' = 4π (12) ( - 1/ 4320π)

      = -1/90 cm²/sec.

Decrease in surface area = 1/90 cm²/sec.

Therefore, when the outer diameter of the ball with ice on it is 24 cm then the outer surface area of ice changes at the rate of 1/90cm²/sec.

Answer:

  -3, 0, 5

Step-by-step explanation:

You want the zeros of P(x) = x³ − 2x² − 15x using the factored form.

We notice right away that x is a factor of every term. Factoring that out gives us a quadratic to factor:

  P(x) = x(x² -2x -15)

To factor this, we need two factors of -15 that have a sum of -2. The factors -5 and +3 have those properties. That means our factored form is ...

  P(x) = x(x +3)(x -5) . . . . factored form

This product will be zero when any of its factors is zero. Considering them one at a time, we find the zeros of P(x) to be ...

  x = 0

  x +3 = 0   ⇒   x = -3

  x -5 = 0   ⇒   x = 5

The zeros of P(x) are -3, 0, 5.

ANSWER

There are 913,952 different 5-letter combinations that can be formed.

EXPLANATION

Recall that there are 26 letters in the English Alphabet.

From the question, we are to find the arrangement of 5 letters with the first letter being either W or K, and repetition of letters is allowed.

The possibilities for the 1st letter is 2 since the 1st letter can be either W or K;

More so, the possibilities for the 2nd letter is 26;

The possibilities for the 3rd letter is 26;

The possibilities for the 4th letter is 26, and

The possibilities for the 5th letter is 26;

The possibilities of arranging 5 letters = 2 x 26 x 26 x 26 x 26 = 913,952.

Hence, a total of 913,952 different 5-letter combinations can be formed.
