Answer:
[tex](b\circ a)(x)=3x-3[/tex] ; the domain is all real numbers
Step-by-step explanation:
[tex]a(x) = 3x+1[/tex]
[tex]b(x)=x-4[/tex]
[tex](b\circ a)(x)=b(a(x))=b(3x+1)=(3x+1)-4=3x+1-4=3x-3[/tex]
Therefore, the domain of the composite function is all real numbers.

Step-by-step explanation:
To compute a value for the table put the given "input" into the formula and do the arithmetic. Repetitive arithmetic is often easily handled by a graphing calculator or spreadsheet.
Example:
for n=2, C = 40·2 +210 = 80 +210 = 290

Step-by-step explanation:
[tex]3/5*5/6[/tex]
To multiply the find the value of this problem, multiply the numerators and denominators.
Remember, numerators are the numbers above the fraction bar.
Denominators are the numbers below the fraction bar.
Numerators: 3, 5
Denominators: 5, 6
[tex]3*5=15[/tex]
[tex]5*6=30[/tex]
After finding the products, add the fraction bar.

In most cases, you will be asked to simplify. It does not seem like simplifying is required in this question.
But, I'll simplify anyway.
15/30 = 1/2 (simplified).
The volume of a spherical balloon is increasing at a constant rate of 3 in3/s. At what rate is the radius of the balloon increasing at the instant its radius is 2 inches?
Answer:
0.0597in/s
Step-by-step explanation:
The volume of the spherical balloon V= 4/3πr³
r is the radius of the balloon
The rate at which the volume is changing dV/dt is expressed as;\
dV/dt = dV/dr*dr/dt
dV/dr = 3(4/3πr²)
dV/dr = 4πr²
dV/dr = 4π(2)²
dV/dr = 16π
dV/dt = 3 in³/s
Substitute inti the formula
3 = 16πdr/dt
dr/dt = 3/16π
dr/dt = 3/50.24
dr/dt = 0.0597in/s
Hence the balloon is increasing at the rate of 0.0597in/s

A square park has an area of 1/16 square miles and a length of 1/4 mile. What is
the width of the park?
9514 1404 393
Answer:
1/4 mile
Step-by-step explanation:
The length and width of a square are the same.
The length is 1/4 mile, so the width of the park is 1/4 mile.
A square park has an area of 1/16 square miles and a length of 1/4 mile. What is the width of the park?
The formula for width is:[tex]\quad \quad \quad \boxed{ \tt{width = \frac{area}{length}}}[/tex]
Lets try![tex]\quad \quad \quad{\tt{w = \frac{1}{16} \div \frac{1}{4} = \boxed{\tt{0.25}}}}[/tex]
Lets convert it to fraction:[tex]\quad \quad \quad \boxed{ \tt{w = 0.25}} \: ➡ \boxed{ \tt{w = \frac{1}{4}}}[/tex]
So the value of width is:[tex]\boxed{ \tt{w = \frac{1}{4}}}[/tex]

Select the correct answer.
Consider the function f(t) = 2* and function g.
g(t) = (1) + 6
How will the graph of function g differ from the graph of function f?
ΟΑ.
The graph of function g is the graph of function fshifted 6 units to the left.
B.
The graph of function g is the graph of function fshifted 6 units up.
Ос.
The graph of function g is the graph of function fshifted 6 units to the right.
OD.
The graph of function g is the graph of function fshifted 6 units down.
Answer:
The graph of function g is the graph of function f shifted 6 units up.
Step-by-step explanation:
Given
[tex]f(x) = 2^x[/tex]
[tex]g(x) =2^x + 6[/tex]
Required
Compare g(x) to f(x)
Substitute [tex]f(x) = 2^x[/tex] in [tex]g(x) =2^x + 6[/tex]
[tex]g(x) = f(x) + 6[/tex]
This implies that f(x) is shifted 6 units upward to give g(x)

Larissa dives into a pool that is 8 feet deep. She touches the bottom of the pool with her hands 6 feet horizontally from the point at which she entered the water.
What is the approximate angle of elevation from the point on the bottom of the pool where she touched to her entry point?
36.9°
41.4°
48.6°
53.1°
Answer:
It would be 53.1
Step-by-step explanation:
Vote branlyist Please...
The approximate angle of elevation from the point on the bottom of the pool where she touched to her entry point is; D: 53.1°
What is angle of elevation?We are told that she dived into the pool that was 8 ft deep.
She touches the bottom with her hands 6 ft horizontally.
Thus, a triangle is formed here with 8 being the opposite side of the angle of elevation and 6 being the adjacent side of the triangle.
Using trigonometric ratios, we can say that;
θ = tan⁻¹(8/6)
θ = 53.1°

How many inches is the circumference of this circle?
Type in your answer WITH NO LABEL, JUST THE NUMBER.
Answer:
Diameter(line going across the circle that you've given) = 6 in
Radius(half of diameter) = 3 in
Circumference(the perimeter of the circle) = 18.85 in
Area = 28.27^2
Step-by-step explanation:
In order to find the circumference, you will need to first find the radius(which is always half the size of the diameter which in this case is 3 in). You will then need to do this formula: 2 x 3.14 x 3 which equals to 18.85.
Answer:
The circumference of a circle is about 18.85 inches.
Step-by-step explanation:
The radius is always half of the diameter, and the diameter is 6 inches.
6 divided by 2 is 3, so the radius of this circle is 3 inches.
The formula for circumference of a circle is :
C = 2πr = 2 · π · 3 ≈ 18.84956
The circumference of a circle is about 18.85 inches.

Answer:
15.7
Step-by-step explanation:
Because the width has to be bigger than the length since its a rectangle and 15.7 matches the equation of 43.8 and 12.4
Answer:
P = 2(l + w)
43.8 = 2(12.4 + x )
43.8 = 24.8 + 2x
43.8 - 24.8 = 2x
19 = 2x
Divide both side by two;
x = 9.5 ft
