Answer:

g(f(x)) = 9x² + 15x + 4

Step-by-step explanation:

Given :

⇒ f(x) = 3x + 4

⇒ g(x) = x² - 3x

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

Solving :

⇒ g(f(x))

⇒ g(3x + 4) = (3x + 4)² - 3(3x + 4)

⇒ g(3x + 4) = (3x)² + 2(3x)(4) + (4)² - 9x - 12

⇒ g(3x + 4) = 9x² + 24x + 16 - 9x - 12

⇒ g(f(x)) = 9x² + 15x + 4

At the end of 12 weeks, Ai Mi has run 22 miles.

As mentioned in the question, Ai Mi just started a running plan where she runs 12 miles the first week and then increases the number of miles she runs by 5% each week.

The function which is in format f(x) =a^x  where a is constant and x is variable,  the domain of this exponential function lies   (-∞, ∞).

here,
Let the total run be x, for 12 weeks
According to the question,

x = 12×(1 + 5%/100)¹²
x = 12(1.05)¹²
x = 21.55
x ≈ 22 miles

The percentage of the runner from team B that finishes the race is 21.4%

How to find the percentage that finish the race from team B?

Team A and Team ran a race. Team A had 28 runners and Team B also had 28 runners.

4 runners from team A finishes the race while 12 runners from team B finishes the race.

Therefore, the percentage from team B that finishes the race can be calculated as follows.

percentage from team B that finishes = 12 / 56 × 100

percentage from team B that finishes = 1200 / 56

percentage from team B that finishes = 21.4285714286

Answer:

x=10

y=[tex]10\sqrt{3}[/tex]

Step-by-step explanation:

Since there is a 30 degree angle, it is a special right triangle, 30 60 90 triangle. The shorter leg represents "a," the longer leg represents "a√3", and the hypotenuse represents 2a.

The triangle has a hypotenuse of 20 and we are trying to find x and y. x=10 because x is the opposite side of 30 degrees and x is half of the hypotenuse. y=[tex]10\sqrt{3}[/tex] because we already know the x value and y is opposite of 60 degrees. As mentioned before, the longer leg represents a√3.

Answer:

  A. 14040 cubic inches

  B. 61 gallons

Step-by-step explanation:

The volume of a cuboid is given by the formula ...

  V = LWH

__

One yard is 36 inches, so 1 yard 3 inches is 36 +3 = 39 inches.

One foot is 12 inches, so 1.5 ft = 1.5×12 = 18 inches.

The volume of the fish tank is ...

  V = (39 in)(18 in)(20 in) = 14,040 in³

The volume is 14,040 cubic inches.

__

One gallon is 16 cups, so 976 cups is 976/16 = 61 gallons.

976 cups equals 61 gallons.

_____

Additional comment

One gallon is 231 cubic inches, so the volume of the tank is actually about 972 cups, or 60.8 gallons.

64 = r^2

square root both sides

r = 8.

Now since we know the raidus we can find the circumferewnce.

Explanation:

1 gallon = 4 quarts

2 gallons = 8 quarts

1/4 of 8 quarts = 2 quarts

She used 2 quarts for her bedroom and 3 for the hallway. Therefore, she used 2+3 = 5 quarts total.

That leaves 8 - 5 = 3 quarts for the living room.

Answer:

A: 3 Quarts

Step-by-step explanation:

1 gallon = 4 quarts

1/4 of 2 gallons = 1/4 × 2

                         = 1/2 gallon

⇒ 1/2 gallon = 2 quarts

Therefore, Mieko used 2 quarts of paint to paint her bedroom.

If she used 3 quarts to paint the hallway, then

⇒ total number of quarts used = 2 + 3 = 5 quarts

As she bought a total of 2 gallons of paint:

⇒ 2 gallons = 2 × 4 = 8 quarts

Therefore the remaining unused paint (to paint the living room) is:

⇒ total paint - used paid = 8 quarts - 5 quarts

                                         = 3 quarts

Step-by-step explanation:

Let (x1,y1) = (5,5) and (x2,y2) = (8,1)

By using distance formula,

Answer:

first you have to order the numbers

8, 10, 13, 18, 23, 25, 26, 30

Median is between 18 and 23 so we add them then divide the sum by 2

Median: (18 + 23)/2 = 20.5

First Quartile is between 10 and 13 so we add them then divide the sum by 2

First Quartile: (10 + 13)/2 = 11.5

Third Quartile is between 25 and 26 so we add them then divide the sum by 2

Third quartile: (25 + 26)/2 = 25.5
