Answer:

A, 16x^9

Step-by-step explanation:

You apply the function f to x, then apply the function f to that.

f(x)=2x^3

f(f(x))=f(2x^3)=2(2x^3)^3 = 2*2^3*(x^3)^3 = 2*8*x^(3*3)=16x^9

Hi there!

3x-4=6

To find x, add 6 with 4 then divide by 3...

[tex]10[/tex]÷[tex]3=\frac{1}{3}[/tex]

Final Result: x=1/3

Answer:

62%

Step-by-step explanation:

I took a fraction and made a decimal which was made into a percentage.

186 ÷ 300 = .62

Check: 62% • 300 = 186

The survey Anna conducted has 62% of students whose favorite color is red.

The percentage is the value per hundredth. Percentages can be converted into decimal form by dividing them by hundred, Percentage can also be represented as a fraction.

Given that 186 out of 300 students Anna surveyed chooses red as their favorite color.

The percentage of students whose favorite color is red is no. of students whose favorite color is red divided by the total no. of students multiplied by hundred which is,

= (186/300)×100.

= 186/3.

= 62%.

Answer:

1 million

Step-by-step explanation:

Start counting at position 0, the rightmost position has value 10⁰ = 1

The one left to that 10¹ = 10

... and so forth ...

The 6th position has value 10⁶ = 1000000, a.k.a. one million.

The place value of 3 in 553 049 270 is 1 million.

Here the number is given as 553 049 270.

We have to find the place value of 3 in given number.

What is Place value?

Place value is describe the position or place of a digit in a number.

Now,

To find the place value of 3;

Start counting at position 0, the rightmost position has value [tex]10^{0}= 1[/tex]

The position of 7, one left to 0, has value [tex]10^{1} = 10[/tex]

------ and so on.

Now, position of 3 is 6th position has value [tex]10^{6} = 1000000[/tex]

So, The place value of 3 in 553 049 270 is 1 million.

Step-by-step explanation:

-(-4)²+7(-2)⁴-2(-3)³

=16+7(16)-2(-27)

=15+112+54

=181

The evaluation of the expression is 150.

In mathematics, expression is the combination of variables with the application of operations and prescribed rules. It might take the shape of an equation, some numbers, etc.

The given expression is:

-a² + 7b⁴  -2c³

Substituting, a= -4 b= -2 and c=-3

-a² + 7b⁴  -2c³

= -(-4)² + 7(-2)⁴  -2(-3)³

= -16 + 7 x 16 + 54

= 150

Therefore, the value of the expression is 150.

Answer:

Plan A : f(x) = 25 + 8x

Plan B : f(x) = 5 + 12x

Plan A is better if used for more than 5 months (5 - ∞), plan B for 1 - 4 months

Step-by-step explanation:

x represents months

Plan A : f(x) = 25 + 8x

Plan B : f(x) = 5 + 12x

The equilibrium is when both of these functions have the same value

25 + 8x = 5 + 12x

4x = 20

x = 5

Now we compare these two plans before the 5 months,

e. g. when x = 2

The cost of plan A: 25 + 8x = 25 + 8 * 2 = 41$

The cost of plan B: 5 + 12x = 5 + 12 * 2 = 29$

Since 41$ > 29$, for 1-4 months plan B is a cheaper option, then after 5 months the costs of these two plans are equal and then plan A will be the cheaper aka less expensive option.
