What is the value of f(4)?

Answer:

[tex]\frac{1}{72}[/tex]

Step-by-step explanation:

Using the rule of exponents

[tex]a^{-m}[/tex] ⇔ [tex]\frac{1}{a^{m} }[/tex] thus

[tex]2^{-3}[/tex] = [tex]\frac{1}{2^{3} }[/tex] = [tex]\frac{1}{8}[/tex]

[tex]3^{-2}[/tex] = [tex]\frac{1}{3^{2} }[/tex] = [tex]\frac{1}{9}[/tex]

Then

[tex]\frac{1}{8}[/tex] × [tex]\frac{1}{9}[/tex] = [tex]\frac{1}{72}[/tex]

Answer:

1/72.

Step-by-step explanation:

2^-3 = 1 / 2^3 = 1/8.

3^-2 = 1/3^2 = 1/9

So the answer is 1/8 * 1/9

= 1/72.

Answer:

B

Step-by-step explanation:

the area of a triangle is

[tex]A=\frac{1}{2}(h)(b)[/tex]

so if we take as

[tex]from\:(x_1,y_1)\rightarrow(x_2,y_1)[/tex]

so the base is

[tex]b=x_2-x_1[/tex]

so the height is

[tex]from\:b\rightarrow(0,0)[/tex]

the distance is

[tex]h=y_1-0[/tex]

so the area is

[tex]A=\frac{1}{2}(y_1+0)(x_2-x_1)\\\\=\frac{1}{2}(y_1)(x_2-x_1)[/tex]

so the answer is B

Answer:

hello some parts of your question is missing attached below is the missing part

answer: the sum Given it can seen that according to the closure property of Rational numbers  the addition of two rational numbers will sum up to a rational number provided that the rational numbers ≠ 0 and a set of rational number is closed under the closures property rule i.e x + y = y + x

Step-by-step explanation:

using the closure property and based on the sum given :

From the sum Given it can seen that according to the closure property of Rational numbers  the addition of two rational numbers will sum up to a rational number provided that the rational numbers ≠ 0 and a set of rational number is closed under the closures property rule i.e x + y = y + x

I've seen a few comments about the answer so the answer the person above me answered is:

"The sum given can seen according to the closure property of rational numbers. The addition of two rational numbers will sum up to a rational number, provided that the rational numbers are ≠ 0 and a set of rational number is closed under the closures property rule, in other words: x + y = y + x."

Answer:

$62.10

Step-by-step explanation:

To calculate how much the employee's discount actually was, we just multiply the original price by the discount

Plug the prices in --> 138 x 45/100

Simplify 45/100 --> 9/20

138/1 x 9/20 = 1242/20

1242/20 = 62.1

62.1 = $62.10

and thus, the discount is $62.10

Answer:

$63.10

Answer:

-4.5/-0.5/0.7/0.3/2.3

Step-by-step explanation:

========================================

Work Shown:

Use law of cosines to find angle B

b^2 = a^2 + c^2 - 2*a*c*cos(B)

9^2 = 6^2 + 12^2 - 2*6*12*cos(B)

81 = 36 + 144 - 144*cos(B)

81 = 180 - 144*cos(B)

81 - 180  = -144*cos(B)

-99  = -144*cos(B)

-144*cos(B) = -99

cos(B) = (-99)/(-144)

cos(B) = 0.6875

B = arccos(0.6875)

B = 46.5674634422102

B = 47 when rounding to the nearest whole number

Make sure your calculator is in degree mode.

arccos is the same as inverse cosine often labeled [tex]\cos^{-1}[/tex] on calculators.

Answer:

The answer is

Step-by-step explanation:

Equation of a line is y = mx + c

where

m is the slope

c is the y intercept

To find the equation of the parallel line we must first find the slope of the original line

The original line is y = 4x + 3

Comparing with the general equation above

Slope = 4

Since the lines are parallel their slope are also the same

Slope of parallel line = 4

The equation of the line using point (1,8) and slope 4 is

[tex] y - 8 = 4(x - 1) \\ y - 8 = 4x - 4 \\ y = 4x - 4 + 8[/tex]

We have the final answer as

[tex]y = 4x + 4[/tex]
