Answer:
3 (second option)
Step-by-step explanation:
g(x) is a piecewise function. To find g(3), you have to see which condition the number 3 satisfies.
Out of the options provided, the only condition 3 satisfies is x≥3.
The equation provided for x being greater than or equal to 3 is 6 - x.
Now we can plug in our x value of 3 and solve.
g(3)= 6 - 3
g(3)= 3

Part A
Which figures have a volume greater than 600 cubic inches?
A. Cylinder #1
B. Cone #1
C. Cylinder #2
D. Cone #2
E. Sphere
Part B
How many times greater is the volume of the Sphere than the volume of
Cone #1? Round your answer to the nearest tenth.
Answer:
A). Options (C) and (E)
B). 4.8 times
Step-by-step explanation:
Part A
Volume of cylinder (1) = πr²h
= π(6)²(5)
= 565.5 cubic inches
Volume of cone (1) = [tex]\frac{1}{3}\pi (r)^2h[/tex]
= [tex]\frac{1}{3}(\pi )(6)^2(5)[/tex]
= 188.5 cubic inches
Volume of cylinder (2) = πr²h
= π(6)²(15)
= 1696.5 cubic inches
Volume of cone (2) = [tex]\frac{1}{3}\pi (r)^2h[/tex]
= [tex]\frac{1}{3}\pi (6)^2(15)[/tex]
= 565.5 cubic inches
Volume of sphere = [tex]\frac{4}{3}\pi r^{3}[/tex]
= [tex]\frac{4}{3}\pi (6)^{3}[/tex]
= 904.8 cubic inches
Figure having volume greater than 600 cubic inches are cylinder (2) and sphere.
Options (C) and (E) are the correct options.
Part (B)
[tex]\frac{\text{Volume of sphere}}{\text{Volume of cone (1)}}[/tex] = [tex]\frac{904.8}{188.5}=4.8[/tex]
Therefore, volume of sphere is 4.8 times the volume of cone (1).

Answer:
x = -149/20
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDASEquality PropertiesStep-by-step explanation:
Step 1: Define equation
2(x + 469/20) = 32
Step 2: Solve for x
Distribute 2: 2x + 469/10 = 32Isolate x term: 2x = -149/10Isolate x: x = -149/20Step 3: Check
Plug in x to verify it's a solution.
Substitute: 2(-149/20 + 469/20) = 32Add: 2(16) = 32Multiply: 32 = 32Here we see that 32 does indeed equal 32. ∴ x = -149/20 is a solution of the equation.
And we have our final answer!
A pair of tangents to a circle which is inclined to each other at an angle of 60 degree are drawn at ends of two radii. The angle between these radii must be :
Answer:
The angle between these radii must be 120º.
Step-by-step explanation:
According to Euclidean Geometry, two tangents to a circle are symmetrical to each other and the axis of symmetry passes through the center of the circle and, hence, each tangent is perpendicular to a respective radius. We represent the statement in the diagram included below.
Then, we calculate the angle of the radius with respect to the axis of symmetry by knowing the fact that sum of internal angles within triangle equals 180º. That is to say:
[tex]\theta = 180^{\circ}-90^{\circ}-30^{\circ}[/tex]
[tex]\theta = 60^{\circ}[/tex]
And the angle between these two radii is twice the result.
[tex]\theta' = 2\cdot \theta[/tex]
[tex]\theta' = 120^{\circ}[/tex]
The angle between these radii must be 120º.

Which answer choice identifies the relevant information in the problem?
Sarah left the house at 12:15 p.m. to go to the store. She spent $42.20 on 2 books for her children and she spent $5.67 on a toys for her dog, Rover. Sarah arrived home at 1:00 p.m. How much did Sarah spend on each book
Answer:
Step-by-step explanation:
Given parameters:
Time of going out = 12:15pm
Amount spend on two books = $42.20
Amount spend toys = $5.67
Time of arrival = 1:00pm
The amount Sarah spent on each of the two books;
= [tex]\frac{total amount spent on the books }{number of books}[/tex]
Amount spent on each books = [tex]\frac{42.20}{2}[/tex] = $21.1 per book
The relevant information to solve this problem are the number of books and the cost of the book.

Answer:
r = no solutions
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDASEquality PropertiesStep-by-step explanation:
Step 1: Define equation
13 - 2(4r - 5) = -(7 + 8r)
Step 2: Solve for r
Distribute: 13 - 8r + 10 = -7 - 8rCombine like terms: -8r + 13 = -7 - 8rAdd 8r on both sides: 13 ≠ -7Here, we see that 13 does not equal -7. ∴ r has no solutions.

B' → [tex](1 + 4, -1 + 2) = (5, 1)[/tex]
C' → [tex](-7 + 4, -3 + 2) = (-3, -1)[/tex]

B' = (5, 1)
C' = (-3, -1)
The new coordinates are obtained as A'(-4, 7), B'(3, 1) and C'(-3, -1) respectively.
How to transform a graph of the function?The graph of a function can be transformed by either shifting it in the right, left, up or down.
When the transformation is rightwards, the function becomes as f(x - a).
For left shifting it is f(x + a).
And, for up and down shift it is a + f(x) and a - f(x) respectively.
The new coordinates after the transformation is given as follows,
Apply the given transformation (x,y) → (x + 4,y + 2) as below,
The coordinates of A' are (-8 + 4, 5 + 2) = (-4, 7).
The coordinates of B' are (-1 + 4, -1 + 2) = (3, 1).
The coordinates of C' are (-7 + 4, -3 + 2) = (-3, -1).
Hence, the coordinates after the transformation become as A'(-4, 7), B'(3, 1) and C'(-3, -1).
