Geologists have taken a collection of samples of a substance from a proposed mining site and must identify the substance. Each sample is roughly cylindrical, and the volume of each sample as a function of cylinder height (in centimeters) is V(h) = 1/4 πh^3. The mass (in grams) of each sample in terms of height can be modeled by M(h) = 1/4 h^3 − h2 + 5h. Write an expression that represents the density of the samples.
(Hint: D = M/V)

D(h) = __________

Answers

The expression that represents the density is D = h^2 - 4h + 20/pi h^2

Uma piscina possui 5 m de comprimento, 3 m de largura e 2,5 m de profundidade. Calcule: a) A quantidade de azulejo necessária para forrar a piscina b) A quantidade de água que cabe nessa piscina. c) seu volume em m3

Answers

Answer:

a) 70 azulejos

b) 37500 litros

c) 37.5m³

Step-by-step explanation:

A piscina tem 5 m de comprimento, 3 m de largura e 2,5 m de profundidade.

Comprimento = 5m

Largura = 3m

Profundidade (altura) = 2,5 m

Calcular:

a) A quantidade de ladrilhos necessária para cobrir a piscina

Isso é calculado como a área de superfície da votação

A = 2 (wl + hl + hw)

A = 2 × (3 × 5 + 2.5 × 5 +2.5 × 3)

A = 70 m²

Observe que:

1 m² = 1 azulejo

70 m² = 70 azulejos

b) A quantidade de água que pode caber na piscina.

1 m³ = 1000 litres

O volume de uma piscina = Comprimento × Largura × Altura

= 5m × 3m × 2.5m

= 37.5m³

1 m³ = 1000 litros

37.5m³ =

37.5 × 1000 litros

= 37500 litros

c) seu volume em m³

O volume de uma piscina = Comprimento × Largura × Altura

= 5m × 3m × 2.5m

= 37.5m³

Jim keeps track of his driving so that he can take a tax deduction. Jim drove 450 miles last month, in comparison to 261 miles this month. By what percent has his monthly driving decreased?

Answers

Answer:

42% decrease

Step-by-step explanation:

To get the percent increase or decrease, subtract 450 by 261 to get 189. Then divide this by 450 to get 0.42. Multiply this by 100 to get a 42 percent decrease.

Answers

Answer:

The correct answer is d.

Step-by-step explanation:

Let's solve each answer and see which one matches.

Note that in each case, you simply add or subtract from x inside the radical to move left or right respectively.  Similarly, just add or subtract to the full expression to move up or down respectively. Doing so we get:

a) [tex]f(x) = \sqrt[3]{x + 7} + 3[/tex]

b)[tex]f(x) = \sqrt[3]{x - 3} - 7[/tex]

c)[tex]f(x) = \sqrt[3]{x - 3} + 7[/tex]

d)[tex]f(x) = \sqrt[3]{x - 7} + 3[/tex]

So d is the correct answer.

A train traveled at a speed of 60 miles per hour for 5 hours. How far did the train travel?
O 12 miles
O 30 miles
O 120 miles
O 300 miles

Answers

Answer:

d

Step-by-step explanation:

The train traveled for a distance of 300 miles

What is Speed?

Speed is defined as the rate of change of position of an object in any direction. Speed is measured as the ratio of distance to the time in which the distance was covered. Speed is a scalar quantity as it has only direction and no magnitude

Speed = Distance / Time

Given data ,

Let the speed of the train be S = 60 miles per hour

The time taken by the train to reach the destination = 5 hours

So ,

The distance traveled by the train = Speed of the train x Time taken

                                                         = 60 x 5

                                                         = 300 miles

Therefore , the distance traveled by the train is 300 miles

Hence , The train traveled for a distance of 300 miles

Calculate the discriminant and determine the type and number of solutions for each quadratic equation. 2x2−28x=−48 discriminant: Number of solutions: Type of Solutions: Rational or irrational:

Answers

Answer:

Discriminant = 100

Number of solutions = 2

Type of solution = Real and Unique

Rational or Irrational: Rational

Step-by-step explanation:

Given the quadratic expression;

[tex]2x^2 - 28x= - 48 \\[/tex]

Rewrite in standard form

[tex]2x^2 - 28x+ 48= 0 \\[/tex]

Divide through by 2;

[tex]x^2 - 14x + 24 = 0[/tex]

From the expression;

a = 1, b = -14 c = 24

Discriminant determines the nature of the root of the quadratic equation;

Discriminant D = b² - 4ac

Substitute the given values;

D = (-14)² - 4(1)(24)

D = 196 - 96

D = 100

Since the discriminant is greater than zero this means that the solution will be real and unique values.

Get the number of solutions;

Using the formula;

x = -b±√D/2a

x = -(-14)±√100/2(1)

x = 14±10/2

x = 14+10/2 and 14-10/2

x = 24/2 and 4/2

x = 12 and 2

Hence the equation has 2 solutions.

The solutions are rational since we can write then as a ratio of two integers

A cereal company is putting 1 11 of 4 44 prizes in each box of cereal. The prizes are evenly distributed so the probability of winning any given prize is always 1 / 4 1/41, slash, 4.

Answers

Answer:

0.75

Step-by-step explanation:

The complete question is attached below.

The dots on the numbers of the dot plot represent the number of boxes it took Vera to get all the prizes.

Therefore, the probability of getting all the prizes in 9 or fewer boxes is the sum of the number of times it took her to get 4 prizes in 9 boxes or fewer.

Hence:

P(x ≤ 9) = P(x = 4) + P(x = 5) + P(x = 6) + P(x = 7) + P(x = 8) + P(x =9)

P(x ≤ 9) = (4 / 36) + (6 / 36) + (3 / 36) + (4 / 36) + (4 / 36) + (6 / 36)

P(x ≤ 9) = 27 / 36

P(x ≤ 9) = 3 / 4 = 0.75

Answers

Answer:

2nd and 4th options are correct

Step-by-step explanation:

Here, let’s work with the number of tablespoon of lemon juice

From the question ;

2 servings = 1/2 tea spoon

So 4 servings = 2 * 1/2 = 1 tea spoon

Let us convert this to table spoon

3 teaspoon = 1 table spoon

1 teaspoon = x table spoon

3 * x = 1

x = 1/3 tablespoon

As we can see, this is not any part of the options

Let us check for 6 servings

6 servings = 3 * 1/2 = 1.5 tea spoon

From the question;

3 tsp = 1 tbsp

1.5 tsp = x tbsp

x * 3 = 1.5

x = 1.5/3

x = 1/2 tbsp

As we can see, second option is correct

second part

we are working with vinegar

For 2 servings = 2 tbsp of vinegar

4 servings = 2 * 2 = 4 tbsp of vinegar

From the question

2 tbsp = 1/8 cup

4 tbsp = x cup

x = (4 * 1/8)/2 = 1/2/2 = 1/4 cup

For 6 servings

= 3 * 2 = 6 tbsp

From the question;

2 tbsp = 1/8 cup

6 tbsp = x cup

2 * x = 6 * 1/8

x = 6 * 1/8 * 1/2

x = 3/8 cups of vinegar

So therefore, options 4 and 2 are correct

f(x) = 2x^2 – 7x – 6
Find f(6)

Answers

Answer:

f(6)=24

Step-by-step explanation:

[tex]f(x) = 2x^2 - 7x - 6\\f(6) = 2(6)^2 - 7(6) - 6=2*36-42-6=24[/tex]

Answer:

f(6) = 24

Step-by-step explanation:

f(x) = 2x² – 7x – 6: f(6)

f(6) = 2(6)² - 7(6) - 6

= 2 × 36 - 42 - 6

= 72 - 48

f(6) = 24

Thus, f(6) = 24

a birthday cake at the bakery was $30 originally. During a sale, a discount of 28% was given. A further 15% discount was given to those customers who ordered a month earlier. How much would a customer who orders a month earlier need to pay for the birthday cake during the sale?​

Answers

Answer:

$18.36

Step-by-step explanation:

In this question, we have to find the cost of the cake for the customer who orders a month early.

We know that the original price of the cake is $30.

We also know that there was a 28% discount and a 15% discount added to the purchase.

Remember, You don't add discount percentages together, you discount the prices separately.

Solve:

First, apply the 28% discount.

30 · 0.28 = 8.40

30 - 8.40 = 21.60

Now apply the 15% discount to the new price.

21.60 · 0.15 = 3.24

21.60 - 3.24 = $18.36

They needed to pay $18.36 for the cake.
