Answer:
V ≈ 7186 in³
Step-by-step explanation:
The volume of a cone of base radius r and height h is V = (1/3)(π)(r^2)(h).
When h = 15 in and r = 12 in, the volume of the cone is
V = (1/3)(π)(12 in)²·(15 in), or approximately V ≈ 7186 in³

the points (-15, -3) and (-7, -1) both lie on the graph of the linear function y =f(x). What is the rate of change of f(x) with respect to x?
F: 4
H: 1/4
G: -4
J: - 1/4
Answer:
Step-by-step explanation:
The rate of change, m, is defined as
m=(y2-y1)/(x2-x1), in this case we have points (-15,-3) and (-7,-1) so
m=(-1+3)/(-7+15)
m=2/8
m=1/4

7) Option 1
Step-by-step explanation:
1) [tex]y = x^2 + 4x + 3[/tex]
Lets split the middle term.
[tex]=> y = x^2 + 3x + x + 3[/tex]
[tex]=> y = x(x+3) + 1(x + 3)[/tex]
[tex]=> y = (x+1)(x+3)[/tex]
∴ [tex]x = -3 , -1[/tex]
2) [tex]y = 8x^2 - 22x + 5[/tex]
Lets split the middle term.
[tex]=> y = 8x^2 - 20x - 2x + 5[/tex]
[tex]=> y = 4x(2x - 5) - 1(2x - 5)[/tex]
[tex]=> y = (2x - 5)(4x - 1)[/tex]
∴ [tex]x =\frac{1}{4} , \frac{5}{2}[/tex]
3) [tex]y = x^2 - 5x[/tex]
[tex]=> y = x(x - 5)[/tex]
∴ [tex]x = 0 , 5[/tex]
4) [tex]y = 12x^2 + 18x[/tex]
[tex]=> y = 6x(2x + 3)[/tex]
∴ [tex]x = \frac{-3}{2} , 0[/tex]
5) [tex]y = x^2 - 7x + 12[/tex]
Lets split the middle term.
[tex]=> y = x^2 -3x - 4x + 12[/tex]
[tex]=> y = x(x - 3) - 4(x - 3)[/tex]
[tex]=> y = (x - 3)(x - 4)[/tex]
∴ [tex]x = 3,4[/tex]
6) [tex]y = 3x^2 + 10x + 8[/tex]
Lets split the middle term.
[tex]=> y = 3x^2 + 6x + 4x + 8[/tex]
[tex]=> y = 3x(x + 2) + 4(x + 2)[/tex]
[tex]=> y = (x + 2)(3x + 4)[/tex]
∴ [tex]x = -2 , \frac{-4}{3}[/tex]
7) [tex]y = x^2 - 4x - 45[/tex]
Lets split the middle term.
[tex]=> y = x^2 - 9x + 5x - 45[/tex]
[tex]=> y = x(x - 9) + 5(x - 9)[/tex]
[tex]=> y = (x - 9)(x + 5)[/tex]
∴ [tex]x = -5 , 9[/tex]

Answer:

Step-by-step explanation:
Which graph represents a phase shift of pi/2 units right for the graph of
y = cosx?
A. y = sinx
B. y = secx
C. y = csex
D. y = cos(x+pi/2)
Answer:
y=sinx
Step-by-step explanation:
Option (A) y = sinx is the graph that represents a phase shift of pi/2 units right for the graph of y = cosx is the correct answer.
What is trigonometry?Trigonometry is mainly concerned with specific functions of angles and their application to calculations. Trigonometry deals with the study of the relationship between the sides of a triangle (right-angled triangle) and its angles.
For the given situation,
The function is y = cosx.
Plot the function on the graph as shown.
Now draw the functions that are in options to check for phase shift.
A) y = sinx
Plot y = sinx in the graph as shown below. Now it is clearly seen that a phase shift of pi/2 units right for the graph of y = cosx is y= sinx.
In the graph,
The cosx is shown as red wave and sinx is shown as blue wave.
Hence we can conclude that option (A) y = sinx is the graph that represents a phase shift of pi/2 units right for the graph of y = cosx is the correct answer.

c) x=1.23
Step-by-step explanation:
a =3
b=2

2×3=6
-2+or - 9.38 all that divided by 6
-2+9.38= 7.38÷6
x=1.23
or
-2-9.38 all divided by 6
-2-9.38= -11.38 ÷6
x= -1.9
all in all x can't be negative meaning x=1.23
Choose the correct solution for the inequality:
-4x + 5 >-5
A: x < 2.5
B: X > 2.5
C: X <-2.5
D: X > -2.5
Answer:
A
Step-by-step explanation:
We have -4x > -10, so 4x < 10
Answer:
A. x < 2.5
Step-by-step explanation:
you subtract 5 on both sides
then you get -4x > -10.
then you divide -4 on both sides
and you get x<2.5

how much is 48 from 12,5%
Answer:
6, but the question makes more sense when asking about 12.5% from 48
Step-by-step explanation:
to get a percentage of something, we just have to remember that [tex]X\% = \frac{X}{100}[/tex] and that we just need to multiply.
Yes, percentages are just numbers, but the percentage sign lets us signify the purpose of a number.
48 * 12.5% = 48 * 0.125 = 48 / 8 = 6

which statement about the ordered pair ( -6 , 8 ) is true
Answer:
Option A
Step-by-step explanation:
System of the equations has been given as,
5x + 3y = -6 -------(1)
2x + y = -4 ------(2)
Equation (2) multiplied by 3 then subtracted from equation (1),
(5x + 3y) - 3(2x + y) = -6 - 3(-4)
5x + 3y - 6x - 3y = -6 + 12
-x = 6
x = -6
From equation (2),
2(-6) + y = -4
y = 12 - 4
y = 8
Therefore, (-6, 8) is the only solution of the given system of equations.
Option A will be the answer.

For 5 months Tomas buys 4 boxes of crunchy granola bars and 3 boxes of chewy granola bars for his family.
Crunchy bars come in x bars and chewy granola bars come in y bars. Which two expressions can be used to
show the total number of granola bars Tomas buys.
x bars <4> and y bars come in <3>
Answer:
5(4x + 3y) = 20x + 15y
Step-by-step explanation:
The matter of months in which in this case is 5 months is the coefficient.
The amount of boxes per month is important information. We don't know how many bars are in each box. EACH is a key word for multiplying. If we want to know quickly how many bars are in 4 boxes (or 3) of the granola bars. We can simply multiply the amount of bars for each box with the amount of boxes. Since we don't know the amount of bars there are in each box we are going to use a variable. so it would look like this- 4x + 3y BUT we need to add the coefficient. Now rewrite the expression. 5(4x + 3y)
We can use the distributive property to generate an equal expression.
