Answer:

189

Step-by-step explanation:

Aidon walked 11 blocks to begin with than he walks 4 blocks to the library and 12 blocks home. This mean we add 11+4+12=27 and a week has 7 days which means we need to multiply that by 7 which gives us the product of 189.

Answer:

[tex]f-1(x)= \frac{x}{7} +\frac{1}{14}[/tex]

Step-by-step explanation:

If we have y=7x-1/2, the inverse is where we solve for x instead of y.

We can isolate x to get 7x=y+1/2, then divide by 7 to get x=y/7+1/14.

Therefore,[tex]f-1(x)= \frac{x}{7} +\frac{1}{14}[/tex]

Answer:

-6/5

Step-by-step explanation:

3/2x - 5/4y = 15

-5/4y = -3/2x + 15

multiply each side by (-4/5)

(-4/5)(-5/4y) = (-4/5)(-3/2x + 15)

y = -6/5x - 12

rate of change: -6/5

Answer:

The space on each side of the painting = 2 feet

Step-by-step explanation:

Attached this answer is a diagram to give you visuals on how the value of x is calculated

Given:

width of wall = 10 feet

width of painting = 6 feet

Since the painting is centred on a wall, there is meant to be an equal space on each side of the painting, from the diagram, the following eaquation can be gotten

x + 6 + x = 10

2x + 6 = 10

2x = 10 - 6

2x = 4

x = 4 ÷2

x = 2 feet

Therefore, the space on each side of the painting = 2 feet

Answer:

y = 4  (Answer C)

Step-by-step explanation:

We want to find side y.  The sine function relates the 30 degree angle, the hypotenuse 8 and the opposite side y:

                                          y

sin 30 degrees = 1/2 = -----------

                                           8

so y = 4  (Answer C)

▶hOPE IT HELPED!!◀

Answer: No

Step-by-step explanation:

To know if the functions are inverses of each other, it is easiest to just find the inverse of one of the functions. To find the inverse, you want to replace y with x and x with y and solve for y.

y=-8x+5                                  [switch x with y and y with x]

x=-8y+5                                  [subtract both sides by 5]

x-5=-8y                                   [divide both sides by -8]

y=(x-5)/-8

f⁻¹(x)=(x-5)/-8

Since we know that the inverse doesn't match g(x), we know that these functions are not inverses of each other.

Answer:

a. Maurice walked farther.

b. 0.62 m

Step-by-step explanation:

Maurice

4.1 × 1.8 = 7.38 miles

Junnie

2.5 × 3.2 = 8 miles

This shows that Junnie walked more than Maurice.

8 - 7.38 = 0.62

Junnie walked 0.62 m more than Maurice

Answer:

KE = 900,000t²

Step-by-step explanation:

The formula for calculating the kinetic energy of a body is expressed as KE = 1/2mv² where;

m is the mass of the sport car = 2000kg

v is the velocity of the car

Since v = at

v = 30t

Substituting the given values into the KE formula;

KE  1/2 * 2000 * (30t)²

KE = 1000*900t²

KE = 900,000t² Joules where t is the time measured in seconds

Answer:

KE = 900,000t²

Answer:

1. Fixed cost is $800

2.Cost of 25 bags is $1025

3. (170,2300)

Step-by-step explanation:

Given

[tex]c(x) = 10x + 800[/tex]

Solving (a): Fixed cost

From the question, fixed cost is when x = 0;

Substitute 0 for x in [tex]c(x) = 10x + 800[/tex]

[tex]c(0) = 10 * 0 + 800[/tex]

[tex]c(0) = 0 + 800[/tex]

[tex]c(0) = 800[/tex]

Hence, the fixed cost is $800

Solving (b): Cost of making 25 items

Here; x = 25

Substitute 25 for x in [tex]c(x) = 10x + 800[/tex]

[tex]c(25) = 10 * 25 + 800[/tex]

[tex]c(25) = 250 + 800[/tex]

[tex]c(25) = 1025[/tex]

Hence, the cost of 25 bags is $1025

Solving (c): Domain and Range where Maximum cost = $2300

Here; c(x) = 2500

Substitute 25 for c(x) in [tex]c(x) = 10x + 800[/tex]

[tex]2500 = 10x + 800[/tex]

Subtract 800 from both sides

[tex]10x = 2500 - 800[/tex]

[tex]10x = 1700[/tex]

Divide both sides by 10

[tex]x = 170[/tex]

The domain and range of a function is in form of (x,c(x))

Hence, the domain and range is (170,2300)

Step-by-step explanation:

This is because Tia's amount of money minus Dana's amount of money should be at least 5

Answer:

To test the effects of the multi-vitamin, we must test it on people with short-term memory loss. So the population should be people with short-term memory loss. The independent variable is the multi-vitamin and the dependent variable is the short term memory state of the people being tested. A control group can consist of people with short-term memory loss NOT being treated by the multi-vitamin.

Answer:

[tex]6\frac{93}{100} = \frac{693}{100}[/tex]

Step-by-step explanation:

I hope this helps!

Answer:  [tex]6 \frac{31}{33}[/tex]

This is a mixed number where the whole part is 6, and the fractional part is 31/33.

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

Explanation:

The 93 repeats forever, so we can say

x = 6.939393...

100x = 693.939393....

Subtracting the left hand sides leads to 100x-x = 99x

Subtracting the right hand sides leads to 693.939393.... - 6.939393... = 687

Notice how the decimal terms cancel out when we subtract.

We're left with 99x = 687 which solves to x = 687/99

This reduces to 229/33 when you divide both parts by 3.

The last step is to convert to a mixed number

The answer will be in the form [tex]6 \frac{x}{33}[/tex] where 6 is the whole part and x/33 is the fractional part. We know the whole part is 6 from the 6 in the original number given.

229/33 = 6.939393... helps confirm we're on the right track so far

this is another way of saying 229/33 = 6 remainder x, where x is the unknown remainder and the numerator we're after for the fraction x/33.

To get the remainder, we just compute 229-6*33 to get 31

This means 31/33 = 0.93939393...

and that [tex]6 \frac{31}{33} = 6.\overline{93} = 6.93939393...[/tex]

Answer:

square of 36 is 6

or maybe 6²

Answer:332

Step-by-step explanation:

Answer:

Step-by-step explanation:

Given functions are,

f(x) = x³ + 4x²

g(x) = 5x² - 1

(a). (f + g)(x) = f(x) + g(x)

                   = x³ + 4x² + 5x² - 1

                   = x³ + 9x² - 1

   Since the composite function is defined for all values of x, domain of the function will be (-∞, ∞)

(b). (f - g)(x) = x³ + 4x² - (5x² - 1)

                 = x³ - x² + 1

  Domain of the function : (-∞, ∞)

(c). (f.g)(x) = f(x) × g(x)

               = (x³ + 4x²)(5x² - 1)

               = 5x⁵+ 20x⁴ - x³ - 4x²

Domain of the function will be (-∞, ∞).

(d). [tex](\frac{f}{g})(x)=\frac{f(x)}{g(x)}[/tex]

               = [tex]\frac{x^3+4x^2}{5x^2-1}[/tex]

Since this function is not defined at [5x² - 1 = 0] Or x = ±[tex]\frac{1}{\sqrt{5}}[/tex]

Therefore, Domain of the composite function will be,

(-∞, -[tex]\frac{1}{\sqrt{5}}[/tex]) ∪ [tex](-\frac{1}{\sqrt{5}},\frac{1}{\sqrt{5}})[/tex] ∪ ([tex]\frac{1}{\sqrt{5}}[/tex], ∞)
