If there are two functions f(x) and g(x), how f g(x) will be calculated?If there are two functions f(x) and g(x), f(g(x)) will be obtained by replacing x by g(x) into f(x).
So, [tex]m (n(x))= (5x+9)^2+ 3[/tex]
[tex]m (n(x))= 25x^{2} +81+90x +3[/tex]
[tex]m (n(x))= 25x^{2} +90x+84[/tex]

The back of Nico’s truck is 7.5 feet long, 4 feet wide, and 8 feet tall. He has several boxes of important papers that he needs to move. Each box of papers is shaped like a cube, measuring 2.5 feet on each side. How many boxes of papers can Nico pack into the back of his truck? Show your work.
Answer:
Step-by-step explanation: so
l*w*h
7.5ft*4ft*8ft
that would be 240ft^3
Then 2.5^3
would be 15.625^3
So then u would do
240ft^3/15.625ft^3 = 15.36 boxes of paper
So u could fit abt 15 boxes of paper in the back of his truck

How do you write 3.5 × 10^3 in standard form?
Answer:
[tex]3500[/tex]
Step-by-step explanation:
Given the following question:
[tex]3.5\times10^3[/tex]
To convert a scientific notation into standard form we first need to keep in mind that the exponent in indeed a positive. Knowing this we know that the decimal point is going to move to the right.
Since the exponent is three, we know that the decimal point is going to move to the right THREE times.
[tex]3.5\times10^3[/tex]
[tex]3.5\times10^3=3.5.0.0.[/tex]
[tex]3.5.0.0.=3500[/tex]
[tex]=3500[/tex]
Your answer in standard form is "3500."

Find the measure of the missing angle.
Answer:
a = 146
Step-by-step explanation:
The line is 180 degrees so one angle is 34 degrees and the other one would have to add up with it to make 180 degrees. This is where the 146 degrees comes in.
146 + 34 = 180 = degrees

Find the 35th term.
Answer:
the 35th term or a(35) is 69
Step-by-step explanation:
the first thing you must do to solve this equation is to write for the nth term
this is
a(n) = 209 - 4n
i got 209 by adding 4 to 205 to find the 0th term
so to solve the equation for the 35th term oyu just plug it in
a(35) = 209 - 4(35)
a(35) = 209 - 140
a(35) = 69
ABC is a triangle, right-angled at A. If AB = 6 and AC = 8, find BC.
Given :
ABC is a right angled triangle at A where AB is 6cm, AC is 8cm.To Find :
BC.Solution :
Let the Base be AB cm, Perpendicular be AC cm and Hypotenuse be BC.We know that,
[tex] \qquad \sf{ \pmb{(Hypotenuse ) {}^{2} = (Base) {}^{2} + (Perpendicular) {}^{2} }}[/tex]
Substituting the given values in the formula :

A scale model of a ramp is a right triangular prism as given in this figure. In the actual ramp, the triangular base has a height of 1.2 feet. What is the surface area of the actual ramp, including the underside? Enter your answer as a decimal in the box.
The surface area of the actual ramp is 16.8 ft²
What is an area?An area is the amount of space occupied by the two dimensional shape or object.
The height of the actual ramp = 1.2 feet and the height of the model = 6 cm
Scale factor = 1.2 feet / 6 cm = 0.2 ft/cm
Actual base = 16 cm * 0.2 ft/cm = 3.2 ft
9 cm = 9 cm * 0.2 ft/cm = 1.8 ft, 10 cm = 10 cm * 0.2 ft/cm = 2 ft,
Surface area of actual ramp = 2(0.5 * 3.2 ft * 1.2 ft) + 2(2 ft * 1.8 ft) + (1.8 ft * 3.2 ft) = 16.8 ft²
The surface area of the actual ramp is 16.8 ft²

A flag pole casts a shadow that’s 5 feet. A rope attached to the flag is 13 feet long . How tall is the flag poll
Explanation:
I'm assuming the rope is fully taut and connects the top of the flag pole with the tip of the shadow.
Draw a right triangle that has a horizontal leg of 5 feet and a hypotenuse of 13 feet. I'll call these a = 5 and c = 13.
Use the pythagorean theorem to find b
[tex]a^2 + b^2 = c^2\\\\5^2 + b^2 = 13^2\\\\25 + b^2 = 169\\\\b^2 = 169-25\\\\b^2 = 144\\\\b = \sqrt{144}\\\\b = 12[/tex]
The vertical leg of the right triangle is 12 feet, which is the height of the flag pole. We have a 5-12-13 right triangle.

Answer:
(g ￮ f)(- 5) = 4
Step-by-step explanation:
evaluate f(- 5) then substitute the value obtained into g(x)
f(- 5) = (- 5)² + 6(- 5) + 3 = 25 - 30 + 3 = - 2 , then
g(- 2) = 2(- 2) + 8 = - 4 + 8 = 4

Here is a list of numbers.
-45 -21 -16 12 33 40
(a) write down two numbers from the list that add up to -9
Answer:
-21, 12
Step-by-step explanation:
We first have to solve each of the list of numbers:
-45 -21 = -66
-21 - 16 = -37
-16+12=-4
33+40=73
-45-16=-61
-45+33 = -12
-45 + 12 = -33
-21 + 12 = -9
Hence, we can conclude that -21 and 12 add up to -9
