the cube of twice a number

Answers

Answer 1

Answer:

The cube of twice a number.

Twice a quantity usually indicates to take two of the things in question; usually this indicates to multiply by 2. Thus "twice a number x" can be written symbolically as 2x. If this is part of a problem, say twice a number x is 6, then we can rewrite algebraically as 2x=6; dividing both sides by 2 yields x=3.

Step-by-step explanation:

Simplify, and if possible solve the equation to find out

remember, inverse operations

5x - 10 + 2x = 7 + 7x - 17

What in slope-intercept form, can go through the line ( a, 2a) and (-5a, 6a)

Answers

Answer:

y = -2/3x + 8/3a

Step-by-step explanation:

Given points

(a, 2a) and (-5a, 6a)

Slope-intercept form

y = mx + b

Slope of the line is

m = (6a - 2a)/( -5a - a) = 4a/(-6a) = - 2/3

The y-intercept is:

2a = -2/3*a + bb = 2a + 2/3ab= 8/3a

So the line is:

y = -2/3x + 8/3a

Answer:

y = -2/3 - 8/3a

Step-by-step explanation:

Find the slope using [ y2-y1/x2-x1 ]

6a-2a/-5a-a

4a/-6a

-2/3

Find the y-intercept.

y = mx + b

y = -2/3x + b

2a = -2/3(a) + b

-8/3a = b

y = -2/3 - 8/3a

in a stick of chalk carbon is 3 g what is the weight of the chalk stick​

Answers

Answer:

Hence the weight of chalk stick is 25 g.

Explanation:

Let the weight of a stick be x gm.

12% of x=3

(12/100)*x=3

x=3*(100/12)=25 g

Answer:

weight of chalk = 25g

Step-by-step explanation:

let chalk contains 10x calcium, 3x carbon, 12x oxygen.

percentage of carbon in the chalk:

=                  3x              x 100

        10x + 3x + 12x

=  3x    ( 100 )

   25x

= 3 (4)

= 12%

Now, we know that carbon has 12% of chalk.

weight of carbon = 12% x weight of chalk. ------------- equation

plugin values into the equation:

3 = 12% (weight of chalk)

3 =   12     (weight of chalk)

      100

  12     (weight of chalk) = 3

 100

weight of chalk = 3 (100)

                               12

weight of chalk = 25g

Daniel kicks a soccer ball and the trajectory is modeled by f(t) =− 16t^2+ 32t .

a. What would the value be of f(1)?
b. If it takes 2 seconds for the ball to hit the ground, what would a reasonable domain be for this function?

Answers

Answer:

f(1) = 16

Domain: 0 ≤ t ≤ 2

Step-by-step explanation:

Given

f(t) = -16t²+ 32t

Solving (a): f(1)

Substitute 1 for t in f(t)

f(t) =− 16t²+ 32t .

f(1) =− 16 * (1)²+ 32 * 1

f(1) = -16 * 1 + 32

f(1) = -16 + 32

f(1) = 16

Solving (b): The domain

The implication of the given parameter in (b) is that t ≤ 2.

Since t represents time, t can't be negative.

Hence, a reasonable domain is

0 ≤ t ≤ 2

TRUE
FALSE

Answers

The statement radioactive nuclei are highly stable and emit radiation to become unstable is FALSE.

To determine if the statement is true or false we need to know what radiactivity is

What is radioactivity?

Radioactivity is the spontaneous disintegration of unstable atomic nuclei to form stable more energetic nuclei with the emission of radiation.

Radioactivity includes the following

disintegration of a larger atomic nuclei to a smaller more stable nucleiEmission of radiation

So, radioactive nuclei which are unstable emit radiation and become more stable.

So, the statement radioactive nuclei are highly stable and emit radiation to become unstable is FALSE.

Answers

Answer:

B. It is a composite number.

Step-by-step explanation:

143 can be divided by 11 and 13 making it a composite number.

The number 143 is a composite number due to having more than two factors.

The factors of the number 143 are 1, 11 and 13.

What is the difference between a prime number and a composite number?

Prime number has only two factors i.e. 1 and the number itself while composite numbers can have more than two factors.

143 = 1*11*13

Since the number 143 has 3 factors i.e. 1, 11, and 13.
