Hey there! :)
Answer:
B. V = 108 cm³.
Step-by-step explanation:
Find the volume of the triangular prism using the formula:
V = 1/2(bh) where b = l × w
Solve for the base:
b = 4 × 9
b = 36 cm²
Plug this into the formula for the volume:
V = 1/2(36 · 6)
V = 1/2(216)
V = 108 cm³. The correct answer is B.

Step-by-step explanation:
Answer:
136°
Step-by-step explanation:
The angle opposite of x and x are a pair of vertically opposite angles.
Vertically opposite angles are equal in size.
the value of x is: 12. 6. 2. None of the choices are correct.
Answer:
x=6
Step-by-step explanation:
The triangle is an equilateral triangle since all angles are 60 degrees
That means all sides are equal
3x-13 = x-1
Subtract x from each side
3x-13-x = x-1-x
2x-13 =-1
Add 13 to each side
2x= -1+13
2x = 12
Divide by 2
2x/2 =12/2
x = 6
Answer:
B. 6
Step-by-step explanation:
Two angles are 60 degrees, the other is also 60 degrees.
The triangle is an equilateral triangle.
All sides are equal.
3x - 13 = x - 1
3x - x = -1 + 13
2x = 12
x = 6

(ii) Find the remainder when f(x) is
divided by (x - 1)(x + 2).
14) The remainder when the expression
ax' + bx + 2x + c is divided by x-1
is twice of that when it is divided by
x + 1. Show that c = 3a - b + 6.
ii) When a polynomial f(x) is divided by (x-1) and (x+2) it leaves remainder 5 and 17 respectively. find the remainder when f(x) is divided by (x-1) (x+2)
14) The remainder when the expression ax³ + bx² + 2x + c is divided by x-1
is twice of that when it is divided by x + 1. Show that c = 3a - b + 6.
Answer:
ii) R(x) = -4x + 9
14) c = 3a - b + 6 ( Proved)
Step-by-step explanation:
14) The correct expression is [tex]ax^3 + bx^2 + 2x + c[/tex]
To get the remainder when the expression [tex]ax^3 + bx^2 + 2x + c[/tex] is divided by
x - 1, let x - 1 = 0; x = 1
Remainder:
[tex]R_1(x) = a(1)^3 + b(1)^2 + 2(1) + c\\R_1(x) = a + b + 2 + c[/tex]
When [tex]ax^3 + bx^2 + 2x + c[/tex] is divided by x + 1
Let x + 1 = 0; x = -1
Remainder:
[tex]R_2(x) = a(-1)^3 + b(-1)^2 + 2(-1) + c\\R_1(x) = -a + b - 2 + c[/tex]
According to the question, R₁(x) = 2R₂(x)
a + b + 2 + c = 2(-a + b - 2 + c)
a + 2a +b - 2b + 2 + 4 = 2c - c
c = 3a - b + 6 ( Proved)
ii)
The dividend is f(x)
(x - 1)(x + 2) is the divisor, i.e. D(x) = (x - 1)(x + 2)
Let the quotient = A(x)
Let the Remainder, R(x) = ax + b..............(1)
Therefore, f(x) = A(x)D(x) + R(x)
f(x) = A(x)(x - 1)(x + 2) + R(x)...................(2)
When f(x) is divided by x - 1, x = 1
Put x = 1 into equation (2) knowing that R(1) = 5
f(1) = R(1) = 5
R(1) = a(1) + b = 5
a + b = 5....................(3)
When f(x) is divided by x + 2, x = -2
Put x = -2 into equation (2) knowing that R(-2) = 17
f(-2) = R(-2) = 17
R(-2) = a(-2) + b = 17
-2a + b = 17..................(4)
Subtracting equation (1) from (2)
-3a = 12
a = -12/3
a = -4
Substitute the value of "a" into equation (4)
-2(-4) + b = 17
8 + b = 17
b = 9
Since R(x) = ax + b
R(x) = -4x + 9

Step-by-step explanation:
The midpoint of XY is M(0, 4). One endpoint is X(6, –2). Find the coordinate of the other endpoint Y. A.(–6, 10) B.(3, 1) C.(–6, 6) D.(12, 0)
Answer:
The answer is A.
Step-by-step explanation:
Given that the formula for midpoint is :
[tex]m = ( \frac{x1 + x2}{2} , \frac{y1 + y2}{2} )[/tex]
So you have to subtitute the coordinates into the formula :
[tex]let \: m = (0,4) \\ let \: (x1,y1) = (6, - 2)[/tex]
[tex](0,4) = ( \frac{6 + x2}{2} , \frac{ - 2 + y2}{2} )[/tex]
Next, you have to solve it by comparison :
[tex]x⇒ \\ \frac{6 + x}{2} = 0 \\ 6 + x = 0 \\ x = - 6[/tex]
[tex]y⇒ \\ \frac{ - 2 + y}{2} = 4 \\ - 2 + y = 8 \\ y = 10[/tex]

Hope this helped you!
The functions that have a vertex with a x-value of 0 are:
f(x) = |x|
f(x) = |x|+ 3
f(x) = |xl - 6
An absolute value function is of the form:
f(x) = a|x - h| + k
where (h, k) represents the vertex
h is the x-coordinate of the vertex
k is the y-coordinate of the vertex
Comparing each of the options with f(x) = a|x - h| + k, the following absolute value functions have a vertex with x-value of 0.
f(x) = |x|
f(x) = |x| + 3
f(x) = |x| - 6

Answer:
x = 37/45
Step-by-step explanation:
Here's how similar triangles work. We set up an equation as SIDE 1A/ SIDE 1B = SIDE 2A/ SIDE 2B
Ok, so these 2 triangles are similar, so we can set up a butterfly equation:
Side 1a would be 8x
Side 1b would be 5x +3
Side 2a would be 10x - 2
Side 2b would be 7x
----------------------------------------------------
Our equation would be
8x/(5x+3) = (10x-2)/7x
We cross multiply to get 8x(10x-2) = 7x(5x+3)
Instead of solving and getting squares, we can x on both sides and we get:
8(10x - 2) = 7(5x+3) ----> we simplify to get
80x - 16 = 35x + 21 ----> it's easy sailing from here.
45x = 37
x = 37/45

John used digits from 0 to 6 to create a three-digit PIN code. He forgot his PIN code. He remembers that his code contains different ascending digits. What is the maximum number of combinations John has to check to find his PIN code.
Answer:
35 combinations
Step-by-step explanation:
The first digit cannot be 5 or 6 (Since the digits could not be in ascending order if that was the case).
If the first digit is 4, there is 1 possibility:
(4, 5, 6)
If the first digit is 3, there are 3 possibilities:
(3, 4, 5) (3, 4, 6) (3, 5, 6)
If the first digit is 2, there are 6 possibilities:
(2, 3, 4) (2, 3, 5) (2, 3, 6) (2, 4, 5) (2, 4, 6) (2, 5, 6)
If the first digit is 1, there are 10 possibilities :
(1, 2, 3) (1, 2, 4) (1, 2, 5) (1, 2, 6) (1, 3, 4) (1, 3, 5) (1, 3, 6) (1, 4, 5) (1, 4, 6) (1, 5, 6)
If the first digit is 0, there are 15 possibilities:
(0, 1, 2) (0, 1, 3) (0, 1, 4) (0, 1, 5) (0, 1, 6) (0, 2, 3) (0, 2, 4) (0, 2, 5) (0, 2, 6) (0, 3, 4) (0, 3, 5) (0, 3, 6) (0, 4, 5) (0, 4, 6) (0, 5, 6)
Therefore, he would need to try at most 35 combinations.
Which of the following ordered pairs is a solution of the given system of
linear equations?
(4x + 8y = 8
x + 3y = 13
Answer:
x=-14 and y = 9
Step-by-step explanation:
hello
4x + 8y = 8 <=> divide by 4 both parts
(1) x + 2y = 4
(2) x + 3y = 13
(2) - (1) gives
x + 3y -x - 2y = 13 - 4 = 9
<=> y = 9
we replace in (1) x + 2*9 = 4
<=> x = 4 - 18 = -14
so x = -14

Using this distribution, find the probability
that a teenager has 4 or more pairs of shoes
in their closet.
Answer:
P = 0.3
Step-by-step explanation:
Here, we are to use the probability distribution in the table to calculate the probability that a children has 4 or more shoes in his or her closet
When we say 4 or more, what we mean by this is that the teenager has 4 shoes or 5 shoes
In probability expressions, when we use the term ‘or’ we are simply talking about adding the terms involved
So what we can do here is to add the probability that the teenager has 4 shoes to the probability that the teenager has five shoes
From the table that would be; 0.1 + 0.2 = 0.3
Question 26: write the equation that describes the line with slope=5 and y-intercept =8 in slope intercept form.example: y=mx+b
Answer:
y = 5x + 8

Start with y = mx + b: general slope-intercept form, equation of a line:
Replace m with 5, y with 8 and x with 0 (since the y-intercept is (0, 8):
8 = 5(0) + b. Then b must be 8, and the desired equation is
y = 5x + 8

Study the diagram of circle K, where JL¯¯¯¯¯¯¯ and LM¯¯¯¯¯¯¯¯¯ are tangent to circle K at points J and M, respectively. Also, JL=3x+10 and ML=7x−6. What is the length of LM¯¯¯¯¯¯¯¯¯?
22
17.6
16
4
Answer:
22
Step-by-step explanation:
The answer is 22. You solve the equation 3x+10=7x-6 like so
3x+10=7x-6
-3 = -3
10= 4x-6
+6 = +6
16=4x
x=4
You then plug in the value of x to the equation for LM.
7x-6 becomes 7*4-6 which is 22.
An auditorium has its length, breadth, and height equal to 18m. How much air does it contain? An average adult person requires approximately 0.3 cu.M air per hour. The owner of auditorium organizes a concert there. But he limits the duration of concert 3 hours and allows only 6480 tickets to be sold. Why has the owner taken this decision?
Answer:
The volume of air in the auditorium = 5832 cubic meter
Step-by-step explanation:
Length, breadth, and height of the auditorium = 18m
Therefore, the volume of air in the auditorium
[tex]=18 \times 18 \times 18\\=5832 $ cubic meter[/tex]
An average adult person requires approximately 0.3 cu.M air per hour.
Therefore:
6480 adult person will require: 0.3 X 6480 = 1944 cu.M air per hour.
For three hours:
6480 adult person will require: = 1944 X 3 =5832 cubic meter of air
We notice that the volume of air in the room will be exhausted exactly after 3 hours when 6480 persons attend.
Therefore, the owner has taken this decision to avoid suffocation as an increase in the number of tickets or hours will cause such.

Well the formula for the area of a circle is [tex]\pi r^2[/tex].
→Given information
Pi is 3.142
radius is 4 cm
answer must be rounded to the nearest tenth
____________________________________________________________
So now we have to plug in the given information into the following formula [tex]\pi r^2[/tex].
(3.142)(4)^2
So now we have to solve this formula using PEMDAS.
So 4 squared is 16 and 16*3.142 is 50.272cm^2.
The question clearly states the given answer must be rounded into the nearest tenth so 50.272 is 50.3 cm^2.

Answer: D) -4/3
Step-by-step explanation:
Slop can be represented as [tex]\frac{rise}{run}[/tex]. This equation rises -24 units then runs 18. Thus, the slope is -24/18, or -4/3.
Hope it helps <3
Answer:
-4/3.
Step-by-step explanation:
To get the slope, you do the rise over the run.
In this case, the rise is going to be -24, since the track is falling. The run will be 18.
-24 / 18 = -12 / 9 = -4/3
