What are the domain and range of the function Rx) = 4(x2 +6x2+5x-4)?

Answer:

The variable is n

The coefficient is 2

And the solution to n is 10.

Step-by-step explanation:

The number in the equation is the variable. The coefficient is the number before the variable. And a number next to a letter means you multiply. So 2*5=10 10-3=7

The variable is n, the coefficient of the variable is 2 and the value of the variable is 5

In mathematics, a variable is a symbol that represents a mathematical object.

A variable may represent a number, a vector, a matrix, a function, the argument of a function, a set, or an element of a set.

Given is an equation, 2n-3=7, we need to determine the variable, the coefficient of the variable and the solution to the variable n is

Here, we have the variable is n, the coefficient is 2,

Now, solving the equation for n,

Add 3 to both sides

2n-3+3=7+3

2n=10

Divide both side by 2

2n/2=10/2

n=5

Hence, the variable is n, the coefficient of the variable is 2 and the value of the variable is 5

Answer:

36.5625

Step-by-step explanation:

so, if it decays at a rate of 7.5% every 2 days, and we have 234 hours, we do the following, 234/24, since there are 24 hours in a day, that gives us 9.75, "7.5% every 2 days" so we do this, 9.75/2 = 4.875

4.875 * 7.5 = 36.5625

i migt be wrong, but i'm pretty sure this is the answer, i'm not saying this is the answer like some people do, please let me know if i'm wrong.

Answer:

3897.77

Step-by-step explanation:

Decays 7.5%→r=0.075 (divide by 100)

Decays every 2 days: exponent of  t/2

(where t is in days)

function- f(t)=5700(1−0.075) ^t/2

234 hours→234/24→9.75 days

Plug in t=9.75

f(9.75)=5700(1−0.075)  ^9.75/2

Question:

What is 172 divided by 2?

Answer:

Step-by-step explanation:

Step 1:

Start by setting it up with the divisor 2 on the left side and the dividend 172 on the right side like this:

   2 ⟌ 1 7 2

Step 2:

The divisor (2) goes into the first digit of the dividend (1), 0 time(s). Therefore, put 0 on top:

       0    

   2 ⟌ 1 7 2

Step 3:

Multiply the divisor by the result in the previous step (2 x 0 = 0) and write that answer below the dividend.

       0    

   2 ⟌ 1 7 2

      0    

Step 4:

Subtract the result in the previous step from the first digit of the dividend (1 - 0 = 1) and write the answer below.

       0    

   2 ⟌ 1 7 2

     - 0    

       1    

Step 5:

Move down the 2nd digit of the dividend (7) like this:

       0    

   2 ⟌ 1 7 2

     - 0    

       1 7  

Step 6:

The divisor (2) goes into the bottom number (17), 8 time(s). Therefore, put 8 on top:

       0 8  

   2 ⟌ 1 7 2

     - 0    

       1 7  

Step 7:

Multiply the divisor by the result in the previous step (2 x 8 = 16) and write that answer at the bottom:

       0 8  

   2 ⟌ 1 7 2

     - 0    

       1 7  

       1 6  

Step 8:

Subtract the result in the previous step from the number written above it. (17 - 16 = 1) and write the answer at the bottom.

       0 8  

   2 ⟌ 1 7 2

     - 0    

       1 7  

     - 1 6  

         1  

Step 9:

Move down the last digit of the dividend (2) like this:

       0 8  

   2 ⟌ 1 7 2

     - 0    

       1 7  

     - 1 6  

         1 2

Step 10:

The divisor (2) goes into the bottom number (12), 6 time(s). Therefore put 6 on top:

       0 8 6

   2 ⟌ 1 7 2

     - 0    

       1 7  

     - 1 6  

         1 2

Step 11:

Multiply the divisor by the result in the previous step (2 x 6 = 12) and write the answer at the bottom:

       0 8 6

   2 ⟌ 1 7 2

     - 0    

       1 7  

     - 1 6  

         1 2

         1 2

Step 12:

Subtract the result in the previous step from the number written above it. (12 - 12 = 0) and write the answer at the bottom.

       0 8 6

   2 ⟌ 1 7 2

     - 0    

       1 7  

     - 1 6  

         1 2

     -   1 2

           0

You are done, because there are no more digits to move down from the dividend.

The answer is the top number and the remainder is the bottom number.

Therefore, the answer to 172 divided by 2 calculated using Long Division is:

86

0 Remainder

0.172 divided by 2 is equal to approximately 0.086.

To divide 0.172 by 2, you can set up the division like this:

0.172 ÷ 2

To make the division easier, you can convert the decimal 0.172 to a fraction:

0.172 = 172/1000

Now, rewrite the division as a fraction divided by 2:

172/1000÷ 2

To divide fractions, you can multiply the numerator by the reciprocal of the divisor (2):

172/1000× 1/2

Now, multiply the numerators and denominators:

Numerator: 172 × 1 = 172

Denominator: 1000 × 2 = 2000

So, the result is:

172/2000

To simplify the fraction, find the greatest common divisor (GCD) of the numerator (172) and the denominator (2000), and then divide both the numerator and denominator by the GCD.

The GCD of 172 and 2000 is 4.

Divide both the numerator and denominator by 4:

(172 ÷ 4) / (2000 ÷ 4)

This simplifies to:

43/500

=> 43 ÷ 500 ≈ 0.086

So, 43/500 as a decimal is approximately 0.086.

So, 0.172 divided by 2 is equal to approximately 0.086.

Answer:

a) t = 2 seconds

b) 70 feet

Step-by-step explanation:

First of all, we are going to take the derivative of the function (which is a displacement function) to make find its velocity function.

[tex]h(t) = -16t^{2} +64t+6[/tex]

To find the derivative of the equation, we must multiply the coefficient by the exponent and then minus one from the exponent for each term.

[tex]v(t)=(-16)(2)t^{2-1} +64(1)t^{1-1}+6(0)t^{0-1} \\v(t) = -32t +64[/tex]

Now we can substitute in v=0

This is because the ball is at the top of its parabola path, it is the turning point and the slope is 0. The velocity physically speaking would also be 0 at the very top of its path.

[tex]0=-32t+64[/tex]

Rearrange and we get:

[tex]32t = 64\\t=2[/tex]

Ball attains maximum height at 2 seconds.

To find the maximum height, we now just have to substitute back in the time into the original equation to find the height.

[tex]h(t) = -16t^{2} +64t+6[/tex]

[tex]h(2) = -16(2)^{2} +64(2)+6\\h(2)=-64+128+6\\h(2) = 70[/tex]

The maximum height attained is 70 feet.

Hope this helped!

Answer:

After 17 hours there will be about 143 bacteria.

Step-by-step explanation:

Given that in a lab experiment, 80 bacteria are placed in a petri dish, and the conditions are such that the number of bacteria is able to double every 19 hours, to determine how many bacteria would there be after 17 hours, to the nearest whole number, the following calculation must be performed:

80 x ((2/19) x 17) = X

80 x (0.1052 x 17) = X

80 x 1.7894 = X

143.15 = X

Thus, after 17 hours there will be about 143 bacteria.
