Answer:

3^2 ; Option B

Step-by-step explanation:

We are given the equation 3^ -6 * ( 3^4 / 3^0 )^2, which can be solved through the application of exponential rules;

[tex]3^{ - 6 } * ( 3^{ 4 } / 3^{ 0 } )^{2} - take 3^{ 0 } as 1,\\\\3^{ - 6 } * ( 3^{ 4 } / 1 )^{2} - take 3^{4} to power of 2, ( * of exponents ),\\\\3^{ - 6 } * ( 3^{ 8 } ) - combine powers, adding exponents,\\\\3^{ - 6 + 8 } - add like terms,\\\\3^{2} \\\\Solution; 3^{2}[/tex]

3^2 ; Option B

Answer:

The answer would be [tex]3^{2}[/tex].

Step-by-step explanation:

-Solve the following equation:

[tex]3^{-6} \times ( 3^{4} \div 3^{0})^{2}[/tex]

-When dividing integers, the exponents would subtract each other. So, you subtract exponent [tex]0[/tex] and [tex]4[/tex]:

[tex]3^{-6} \times ( 3^{4} \div 3^{0})^{2}[/tex]

[tex]3^{-6} \times ( 3^{4})^{2}[/tex]

-Simplify [tex]3^{4}[/tex] by the exponent [tex]2[/tex]:

[tex]3^{-6} \times ( 3^{4})^{2}[/tex]

[tex]3^{-6} \times 3^{8}[/tex]

-When multiplying integers, the exponent would add up together. So, you would add [tex]-6[/tex] and [tex]8[/tex]:

[tex]3^{-6} \times 3^{8}[/tex]

[tex]3^{2}[/tex]

So, the answer is [tex]3^{2}[/tex].

Answer:

pyramid, cone, sphere, cube

Step-by-step explanation:

A symmetrical pattern is one that is arranged in such a way that there is a progressive repetition of a pattern. Each pattern formed is the same with respect to each other.

Eva could form series symmetrical patterns with the shapes he has, which depends on the arrangement of the shapes to form desired pattern.

One simple pattern to be formed is;

pyramid, cone, sphere, cube

pyramid, cone, sphere, cube

pyramid, cone, sphere, cube

pyramid, cone, sphere, cube.

Thus, this would generate four symmetrical continuous patterns.

pyramid, cone, sphere, cube : pyramid, cone, sphere, cube : pyramid, cone, sphere, cube : pyramid, cone, sphere, cube.

Answer:

Step-by-step explanation:

[tex]F\left[X] = 5X +7X -2 =12X-2\\[/tex]

[tex]g\left[x] = -2x^2+4x+5 \\[/tex]

[tex]f(x) - g(x) \\= 12x -2 - ( -2x^2+4x+5)\\=12x-2+2x^2-4x-5\\=2x^2 + 8x -7[/tex]

Answer:

2x^2+8x-7

Step-by-step explanation:

Combine like terms 5x+7x in your f(x) equation.  

f(x) = 12x-2 then subtract g(x) from f(x).

12x-2-(-2x^2+4x+5)

Now distribute the negative to everything in the parenthses to change the signs.

12x-2+2x^2-4x-5.

Now, combine like terms.  12x-4x=8x

Combine -2-5=-7

Next, order expression beginning with largest exponent:

Your answer:  2x^2+8x-7.

Answer:

4.5 ft

Step-by-step explanation:

Given that the two fugures in the question above are similar, it means they have the same shape, even though they are if different sizes, the ratio of their corresponding sides are proportional. Thus,

18/x = 8/2

Let's solve for x as required.

We have,

18/x = 8/2

=>Cross multiply:

18 × 2 = 8 × x

36 = 8x

=>Divide both sides by 8

36/8 = x

4.5 = x

x = 4.5 ft

The first option is our answer = 4.5 ft

Answer:

30 cm

Step-by-step explanation:

The circumference of a circle is

C = 2*pi*r

60pi = 2* pi *r

Divide each side by 2pi

60/2pi = 2 pi r/ 2pi

30 =r

Answer:

Step-by-step explanation:

circumference , c = 60[tex]\pi[/tex] cm

we know circumference of a circle = 2[tex]\pi[/tex]r

ie  2*[tex]\pi[/tex]*r=60[tex]\pi[/tex]

Answer: $13

Step-by-step explanation:

Answer: $13

Step-by-step explanation:

49-36=13

Answer:

[tex]f(x)=\left \{ {{29\,\,for \,\,x\,\leq 250 } \atop {29+0.35(x-250)\,\,for \,x>250}} \right.[/tex]

Step-by-step explanation:

If we call "x" the number of call minutes used with this plan, the piecewise function used to describe it must represent;

a) a constant value of 29 for any x value smaller than or equal to 250

b) a line with positive slope of 0.35 for the region with x larger than 250. The mathematical representation of such increasing straight line, should be given by a line of slope m = 0.35, and containing the point (250, 29) which is the starting point for this right hand side portion of the domain:

[tex]f(x)=0.35(x-250)+29\\f(x)=0.35 x-87.5+29\\f(x)=0.35 x-58.5[/tex]

So the function should look like:

[tex]f(x)=\left \{ {{29\,\,for \,\,x\,\leq 250 } \atop {29+0.35(x-250)\,\,for \,x>250}} \right.[/tex]

or as shown above, in a more simplified form:

[tex]f(x)=\left \{ {{29\,\,for \,\,x\,\leq 250 } \atop {0.35x-58.5\,\,\,for \,\,x>250}} \right.[/tex]

Answer:

Step-by-step explanation:

Inequalities of the form | x | < a have solutions of the form

- a < x < a

Given

| x - 4 | < 3 , then

- 3 < x - 4 < 3 ( add 4 to the 3 intervals )

1 < x < 7

Thus x > 1 or x < 7

The solution of the given inequality is x < 7 or x > 1.

To solve the inequality Ix - 4| < 3, we can break it down into two cases: when the expression inside the absolute value is positive and when it is negative.

Case 1: x - 4 > 0

In this case, we don't need to consider the absolute value because the expression inside it is already positive.

So we have:

x - 4 < 3

Adding 4 to both sides:

x < 3 + 4

x < 7

Case 2: x - 4 < 0

In this case, the expression inside the absolute value is negative, so we need to negate it when removing the absolute value. Therefore, we have:

-(x - 4) < 3

Expanding the negation:

-x + 4 < 3

Subtracting 4 from both sides:

-x < 3 - 4

-x < -1

Dividing both sides by -1 and flipping the inequality sign:

x > 1

Combining the results from both cases, we have the solution:

x < 7 or x > 1

In interval notation, the solution is (-∞, 1) U (7, +∞).

Hence the solution of the given inequality is x < 7 or x > 1.

Answer:

-8.5

Step-by-step explanation:

17/2 = 8.5

f = 8.5

f -1(17) = 8.5 -17 = -8.5

-8.5 is your answer

The value of [tex]f^{-1}(17)[/tex] is 2.

From the definition of function we know that if f(x) = y , where x and y are two real values having range of (-∝,+∝) , then

[tex]f^{-1}(y) = x[/tex]

Thus in the problem, it is given that f(2) = 17 .

Using the above identity, we can find the value of [tex]f^{-1}(17)[/tex]

∴  [tex]f^{-1}(17) = 2[/tex]
