Answer:

<u>Distance traveled:</u>

  • 3/8 + 1/3 =
  • 9/24 + 8/24 =
  • 17/24

<u>Remaining distance:</u>

  • 1 - 17/24 =
  • 24/24 - 17/24 =
  • 7/24

F(x) = 2x + 3g(x) = 2x² + 6x + 13Find: (gºf)(x)
Butoxors [25]

Answer:

The function (gof)(x) is;

(g\circ f)(x)=8x^2+36x+49

Explanation:

Given the functions;

\begin{gathered} f(x)=2x+3 \\ g(x)=2x^2+6x+13 \end{gathered}

Solving for the function;

(g\circ f)(x)=g(f(x))

so, we have;

\begin{gathered} g(f(x))=2(f(x))^2+6(f(x))+13 \\ g(f(x))=2(2x+3)^2+6(2x+3)+13 \\ g(f(x))=2(4x^2+12x+9)^{}+6(2x)+6(3)+13 \\ g(f(x))=8x^2+24x+18^{}+12x+18+13 \\ g(f(x))=8x^2+24x^{}+12x+18+18+13 \\ g(f(x))=8x^2+36x+49 \end{gathered}

Therefore, the function (gof)(x) is;

(g\circ f)(x)=8x^2+36x+49

I need help figuring this out asap please
Vera_Pavlovna [14]

Answer:

38.13 ft squared

Step-by-step explanation:

Since it is half of a circle we first find the area of a normal circle then divide by two.

So to find the area of  a circle it is pi times radius squared which in this case it would be 3.14 times 9 = 28.26

Then since it is a half circle we divide by two so

28.26/2 = 14.13

Then to find the area of the triangle we do 4 times 6 which is 24.

now we add the two which is 14.13 + 24 which is

38.13

Square root of 12 (\sqrt{12})
Square root of 18 (\sqrt{18})

You can multiply these two together to get:

\sqrt{12 * 18} =  \sqrt{216} = 6 \sqrt{6}

Therefore your answer is 6 square root of 6.

Answer:

Rate = 10%

Step-by-step explanation:

We are given with the following details.

Interest earned = $ 116.25

Principal = $ 1550

Interest Rate = r (say)

Time = 9 months

         = \frac{9}{12} years

We are asked to determine the rate of interest for which we can earn 116.25 interest. As we are not specifically given whether it is a compound or simple interest , we assume it to be simple interest and solve .

The formula for simple interest is given as

Interest = Principal \times Rate \times time

116.25=1550 \times r \times \frac{9}{12}

r= \frac{116.25 \times 12}{1550 \times 9}

r=0.1

Hence the r = 0.1

Hence the rate of interest is 10%
