Answer: D
Step-by-step explanation:
To find f(g(x)), you want to take g(x) and plug that into f(x). Since we are given f(x) and g(x), we can go ahead and do that.
f(g(x))=2(x-3)+4 [distribute]
f(g(x))=2x-6+4 [combine like terms]
f(g(x))=2x-2
Now, we know that f(g(x))=2x-2.

A piece of land is shaped like a right triangle. Two people start at the right angle at the same time, and walk at the same speed along different legs of the triangle while spraying the land. If the area covered is changing at
5 m2/s, how fast are the people moving when they are 5 m from the right angle? (Round approximations to two decimal places.)
Answers
Answer:
1 m/s
Step-by-step explanation:
the area of the triangle = A = ¹/₂ab
where a is the distance covered by the first person and b is the distance covered by the second person. since they walk at the same speed, then a = b, so our formula can be changed to A = ¹/₂x²
now we find the derivative of both sides:
dA/dt = ¹/₂ ⋅ dx²/dt
dA/dt = ¹/₂ ⋅ 2x ⋅ dx/dt
dA/dt = x ⋅ dx/dt = x ⋅ velocity
we are told that x = 5 m, and dA/dt = 5 m²/s
velocity = dA/dt / x
velocity = 5 m²/s / 5 m = 1 m/s

Let's create a system of equations to solve this.
x + y = 72
2x = 10y
Let's solve this equation for x
2x = 10y
Divide both sides by 2
x = 5y
Plug 5y into our first equation to solve for y
5y + y = 72
Combine like terms
6y = 72
Divide by 6
y = 12
x = 5y = 5(12) = 60
Find the range of the given data set.
-4, -3, -1, -1, 0, 1
Answers
Answer:
5
Step-by-step explanation:
To find the range, first order the data from least to greatest. Then subtract the smallest value from the largest value in the set.
Which equation represents the data shown in the table below? x y 2 9 3 12 4 15 5 18 A. y = 2x + 9 B. y = 3x + 3 C. y = 3x + 12 D. y = 4x + 1
Answers
Answer:
Step-by-step explanation:
The answer is B. Because 3 multiplied by x and add it by 3 equates to y. example: (x=2) 3x2+3= y. y=9 .
The data best fit the line y = 3x+3, the correct option is B.
What is an Equation?The equation is a statement that equates two algebraic expressions with an equal sign.
The data is given
x y
2 9
3 12
4 15
5 18
The equation that represents the data can be found by substituting the data and checking if they satisfy the equation.
The first equation is
y = 2x +9
Substitute ( 2,9)
9 = 2 *2 +9
9 ≠ 13
The second equation is
y = 3x +3
Substitute ( 2,9)
y = 3 *2 +3
9 = 9
Substitute ( 3,12)
12 = 3 *3 +3
12 = 12
Therefore, the data best fit the line y = 3x+3, the correct option is B.

The center of circle P is at (-3, 8) and the radius is 12
units. Find its equation.
Answers
Answer:
The answer is
x² + y² + 6x - 16y - 71 =0Step-by-step explanation:
The equation of a circle is given by
( x - a)² + ( y - b)² = r²where ( a , b) is the center of the circle and
r is the radius
From the question the center is
P (-3, 8) and radius = 12
Substitute the values into the above formula and solve
That's
( x + 3)² + ( y - 8) = 12²
Expand the terms
That's
x² + 6x + 9 + y² - 16y + 64 = 144
Arrange the terms
x² + y² + 6x - 16y + 9 + 64 - 144 = 0
We have the final answer as
x² + y² + 6x - 16y - 71 =0Hope this helps you

13. A jeweller bought an engagement ring for €1200 and
sold it at a profit of 15%.
Find the sale price of the ring.
Answers
Answer:
CP of ring = 1200
profit % = 15%
Profit amount = 15% 0f 1200 = 180
SP = 1200 + 180 = 1380
Answer:
€ 1380
Step-by-step explanation:
The jeweller bought the ring for €1200 and got a profit of 15% when he sold it. That means,
[tex] = \frac{15}{100} \times 1200 \\ = 180[/tex]
he got €180 more money (which is equivalent to 15% of the portion of the money that he originally paid for the ring).
So, the selling price (the new price of the ring) would be:
= Original price + profit
= €1200 + €180
= €1380

Well, it's a square, a rhombus and a rectangle.
In geometry, a square is a regular quadrilateral, which means that it has four equal sides and four equal angles (90-degree angles, or 100-gradian angles or right angles). It can also be defined as a rectangle in which two adjacent sides have equal length.
A rhombus is a quadrilateral whose four sides all have the same length.
