the diameter of a cylindrical construction pipe is 4 ft. if the pipe is 19 ft long, what s it’s volume?

Answer:

Step-by-step explanation:

-5x³ + 10x² = 10x² - 5x³   (Commutative property of addition)

                  = 2×(5x²) - x×(5x²)  

                  = 5x² × (2 - x)   (Factor out 5x²)

Answer:

−5x2(x − 2)

Answer:

D

Step-by-step explanation:

Start by factoring out each radical.

[tex]\sqrt{16x^{3}} = \sqrt{16}*\sqrt{x^{3}} = 4\sqrt{x^{3}}[/tex]

[tex]\sqrt{8x} = \sqrt{4} * \sqrt{2x} = 2\sqrt{2x}[/tex]

Add them to get:

[tex]\frac{4\sqrt{x^{3}}}{2\sqrt{2x}} = \frac{4\sqrt{x}\sqrt{x}\sqrt{x}}{2\sqrt{2}\sqrt{x}} = \frac{4\sqrt{x}\sqrt{x}}{2\sqrt{2}} = \frac{2x^{2}}{\sqrt{2}} = \sqrt{2} x^{2}[/tex]

D is the answer

Answer:

(x^4/3)^3/2 = x^a

<=>

x^[(4/3)x(3/2)] = x^a

<=>

x^2 = x^a

<=>

a = 2

Answer:

x>-2

Step-by-step explanation:

x-4x<5x+16

Subtract 5x from both sides:

x-4x-5x<16

Combine like terms:

-8x<16

Divide both sides by 8:

-x<2

Divide both sides by -1:

x>-2

On a coordinate plane, a curve crosses the y-axis at (0, 1). It has a minimum of negative 1 and a maximum of 1. It goes through 2 cycles at 2 pi.

Here we have the function:

y = cos(2*(x + pi))

First, let's distribute the product in the argument of the cosine:

y = cos(2x + 2pi).

Now, notice that 2pi is the period of a cosine function, then:

cos(2x)  = cos(2x + 2pi)

Then we can write:

y = cos(2x)

Now, the y-intercept is:

y = cos(2*0) = 1

And because the factor of 2 inside the argument, it goes through 2 cycle at 2pi (instead of 1 cycle, like a normal cosine).

Then the correct option is:

"On a coordinate plane, a curve crosses the y-axis at (0, 1). It has a minimum of negative 1 and a maximum of 1. It goes through 2 cycles at 2 pi."

x<4

Answer:

x<4

Answer:

x < 4

Step-by-step explanation:

Given inequation,

→ 1/2x + 8 < 10

Now the value of x will be,

→ 1/2x + 8 < 10

→ 1/2x < 10 - 8

→ x < 2 × 2

→ [ x < 4 ]

Hence, the value of x is 4.

Answer:

70,560 ways

Step-by-step explanation:

This problem is an arrangement problem, as the order of the two people chose in each department matters.

So, for each department, we have an arrangement:

First department: arrange of 8 choose 2: A(8,2) = 8!/2! = 8*7 = 56

Second department: arrange of 6 choose 2: A(6,2) = 6!/2! = 6*5 = 30

Third department: arrange of 7 choose 2: A(7,2) = 7!/2! = 7*6 = 42

The total number of ways is the product of each number of arranges, so:

Number of ways = 56 * 30 * 42 = 70,560

Answer:

Substitute (2, 1) into x + 3y = 5 to get  2 + 3(1) = 5

Step-by-step explanation:

I have heard this riddle multiple times, it is very well known and ( in my opinion ) very intriguing;

If we are considering the 4 legs in the morning, we can assume it to be a baby crawling on all 4's. 2 legs in the afternoon represents a more elderly person, a young child or adult on their 2 legs, and 3 in the night models an elderly person, using a walking stick as their " leg "

Answer; In other words, a person has 4 legs in the morning, 2 in the afternoon, and 3 at night

A human is one who has  4 legs in the morning, 2 in the afternoon, and 3 at night.

What is a riddle?

A statement, inquiry, or phrase with a hidden or double sense that is presented as a problem to be answered is called a riddle.

Answer: 76 students

Step-by-step explanation:

Number of students surveyed = 120

Students who 66 ride yellow bus= 66

Students ride city bus = 24

Students who do not ride a bus = 30.

The fraction of students who ride the city bus will be:

= 24/120

= 1/5

Since the total population of the students is 380, the qpproximate for the total number of students that ride the city bus will be:

= 1/5 × 380

= 76 students

13 footballs and 13 basketballs

Step-by-step explanation:

Let f = footballs

b = basketballs

f=b since we are buying an equal number

9f+7b = 208

Substitute f=b

9f+7f = 208

16f = 208

Divide by 16

16f/16 = 208/16

f=13

We are buying 13 footballs

Since f=b

We are buying 13 basketballs

Answer:

Step-by-step explanation:

Let the total population of  grizzly bears=x

In the first capture, 97 were tagged.

Therefore, ratio of the total population to the tagged=x:97

A month later, when 200 bears were captured, 36 were tagged.

Ratio of the sample to the tagged=200:36

Since a sample is representative of the population, the ratios are the same. We therefore have:

x:97=200:36

[tex]\dfrac{x}{97} =\dfrac{200}{36}\\ $Cross multiply\\36x=200 X 97\\x=200 X 97 \div 36\\x=538.9 \approx 539[/tex]

There are about 539 grizzly bears in the population
