Answer:
Step-by-step explanation:there are 4 spaces between each whole number so each line is 1/4 of a whole.
A is 1 space away from 0 so it is 1/4
B is 2 spaces below 0 so is -1/2
Which theorem proves that the triangles are congruent?

A circle passes through the point (2,2) and has its center at (1,-3). The radius of the circle is _ units.
Answer:
radius = [tex]\sqrt{26}[/tex] units
Step-by-step explanation:
The radius r is the distance from the centre to a point on the circle.
Using the distance formula to calculate r
r = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]
with (x₁, y₁ ) = (2, 2) and (x₂, y₂ ) = (1, - 3)
r = [tex]\sqrt{(1-2)^2+(-3-2)^2}[/tex]
= [tex]\sqrt{(-1)^2+(-5)^2}[/tex]
= [tex]\sqrt{1+25}[/tex]
= [tex]\sqrt{26}[/tex]
Which of the following pairs of functions are inverses of each other
Answer:
[tex]f(x) = 5x -11[/tex] and [tex]g(x) = \frac{x + 11}{5}[/tex]
Step-by-step explanation:
Required
The inverse pairs
Solving (a):
[tex]f(x) = 5x -11[/tex] [tex]g(x) = \frac{x + 11}{5}[/tex]
Calculate the inverse of f(x)
[tex]f(x) = 5x -11[/tex]
Replace f(x) with y
[tex]y = 5x - 11[/tex]
Swap x and y
[tex]x = 5y - 11[/tex]
Solve for y
[tex]5y = x + 11[/tex]
[tex]y = \frac{x + 11}{5}[/tex]
So, we have:
[tex]g(x) = \frac{x + 11}{5}[/tex]
Hence, f(x) and g(x) in (a) are inverse functions
Others are not

Answer:
7
Step-by-step explanation:
70+16x-2
68+16x=180
16x=180-112
x=112/16
x=7
Answer:
x = 7
Step-by-step explanation:
70 + 16x - 2 = 180 degree (being co interior angle)
68 + 16x = 180
16x = 180 - 68
16x = 112

Which of the following graphs represents a function that has a positive
leading coefficient? Check all that apply.
determine the equation of the circle graphed below .
Answer:
(x+1)^2 + (y-7)^2 = 2^2
Step-by-step explanation:
The center of the circle is at (-1,7) and the radius from the center to the edge is 2, so the equation should look like (x-h)^2 + (y-k)^2 = r^2
You would flip the signs of the center so that when you solve the equation it ends up in the correct place.

solve px-18=4 for x
Answer:
x=22/p
Step-by-step explanation:
1. Add 18 to 4
2. px=22
3. Divide by p to isolate x
4. 22/p=x
Answer:
x = 22 ÷ p
Step-by-step explanation:
px - 18 = 4
px - 18 + 18 = 4 + 18
px = 22
p · x = 22
x · p = 22
x · p ÷ p = 22 ÷ p
x = 22 ÷ p

a) Find csc ∅, given that cot ∅ = -7/2 and cos ∅ < 0
b) Find cot ∅, given that cos ∅ = 15/17 and ∅ is in Quadrant IV
Answer:
a) csc∅ = √53/2
b) cot ∅ = 15/√514
Step-by-step explanation:
a) The value of cot ∅ = -7/2
cos ∅ < 0
We note that cos(∅) is less than 0 in Quadrant II and III, and cot(∅) is less than 0 in the Quadrant II, therefore, we have;
∅ is in the Quadrant II
csc∅ = (√((-7)² + 2²))/2 =√53/2 ≈ 3.64
csc∅ = √53/2
b) cos∅ 15/17
∅ is in Quadrant IV
∴ cot ∅ = 15/(√(15² + 17²)) = 15/√514 ≈ 0.662
cot ∅ = 15/√514

i) A farm employs 30 men working 40 hours a week. When some of the men are ill, the
rest have to work 50 hours a week to make up the lost time, how many men are ill?
Answer:
hi hi hi hi hi hi hi HI hi hi hi hi hi hi hi hi hi hi hi hi hi
Answer:
6 men are ill.
Step-by-step explanation:
the work of 30 men in 40 hours is the product
30×40
an unknown number of men (x) is sick, and now the remaining workers do the same work in 50 hours
(30-x)×50
so,
30×40 = (30-x)×50
1200 = 1500 - 50x
-300 = -50x
x = 6

The volume of a cylinder, V, in terms of radius, r,
and height, h, is given by V = πr 2
h. If a cylinder has
a height of 6 meters, express the radius as a function
of V and find the radius of a cylinder with volume of
300 cubic meters.
Answer:
See explanation
Step-by-step explanation:
Volume of a cylinder = πr²h
Solve for r
V = π * r² * h
r² = V/πh
Find the square root of both sides
r = √V/πh
If height = 6 meters and volume = 300 cubic meters. Find r
r = √V/πh
= √(300/3.14*6)
= √(300/18.84)
= √15.923566878980
r = 3.9904344223381
Approximately,
r = 4 meters

Answer:
Options : B & D
Step-by-step explanation:
E(x) = 10x - 30 , where x is the number of doors she knocks
Given she has to pay her own expense.
So whatever she earns $30 is reduced from it ,for her expense.
Option A: She can earn $10 even if she does not knock
any doors - False
That is, x = 0
When x = 0 , E (x) = 10 ( 0 ) - 30 = - 30
=> she loses $30.
Option B :Her expenses are $ 30 per week - True
E(x) = 10x - 30
Expenses are reduced from her earnings.
Option C: She will lose $10 per week if she does not knock
any doors - False.
Already checked on option A that if she does not knock
on any door, means x = 0 , then loses $30.
Option D : If she does not knock on any doors at all during
the week , she will lose $30 - True

18 2by5-4 1by10 find the difference
Given:
The expression is:
[tex]18\dfrac{2}{5}-4\dfrac{1}{10}[/tex]
To find:
The difference.
Solution:
We have,
[tex]18\dfrac{2}{5}-4\dfrac{1}{10}[/tex]
It can be rewritten as:
[tex]=\dfrac{90+2}{5}-\dfrac{40+1}{10}[/tex]
[tex]=\dfrac{92}{5}-\dfrac{41}{10}[/tex]
Taking LCM, we get
[tex]=\dfrac{184-41}{10}[/tex]
[tex]=\dfrac{143}{10}[/tex]
[tex]=\dfrac{140+3}{10}[/tex]
[tex]=14\dfrac{3}{10}[/tex]
Therefore, the value of the difference is [tex]14\dfrac{3}{10}[/tex].
Volume=
A) 91 2/3 pie cubic units
B) 275 pie cubic units
C) 36 2/3 pie cubic units
the volume is 1/3 * height *area of the base (the circle) in cubic units
the area of the circle is pi*r²
wich gives us
1/3 * 11 * pi * 5²
rearrange
= 5² * 11 * 1/3 * pi
= 25*11*1/3*pi
= 275*1/3*pi
= 275/3 *pi
= (91 2/3)*pi
in cubic units
so your answer is the first option
