how to find domain and range of a graph
Answer:
the domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the x-axis. The range is the set of possible output values, which are shown on the y-axis.
The diagram above shows a circle with centre O and radius 25 cm.
Given PR = 40 cm, MR = 21 cm and PR = KM, find the perimeter, in cm, of the pentagon OLMRQ.
Answer:
Step-by-step explanation:
Notice that KL = LM and PQ = QR since OL and OQ are perpendicular to both KM and PR.
It follows that QR = (1/2) PR = 20 cm. We also know that MR = 21.
Now in order to solve the problem we just need OQ=OL
[tex]OQ^2=OR^2-QR^2= 25^2-20^2 =225\\OQ=15[/tex]
Therefore the perimeter of the pentagon is
[tex]OL+LM+MR+RQ+Q)\\= 15+20+21+20+15= 91[/tex]

In the figure,
RXQ= 8x-1
RXS= 5x+28
QXS= 3x+5
find RXS
Answer:
RXS=48
Step-by-step explanation:
According to the figure,
RXQ+QXS=RXS
or,8x-1+3x+5=5x+28
or,8x+3x-5x=28+1-5
or,6x=24
or, x=24/6
or,x=4
Then,
RXS=5x+28
=5×4+28
=20+28
=48

Answer:
maybe A? B, D, E
Give brainlest if u agree :)
Step-by-step explanation:
A - Parrallelgrams do indeed have 1 pair of parrlell sides, but are not limited to 1. They in fact have 2 sides. If ur instructor is super literal i would put A, if not then technically a parallelogram has 2 pairs of parrallel sides.
B - True. opposite pairs have the same measure of radians
C - Not true because of B
D - True, sides are same length
E - True, consecutive angles add to 180

What is the solution to the system of equations?
V=
= x + 3
x=-2
Answer: The equations aren't written properly. They seem to be missing something, but if I interpret what is there, we have 1) V = x + 3, and 2) x = -2.
That can't be correct, but if it is, x = -2. and V = 1

Solve for x.
−2(4x+4) - 3x - 2 = 34
Answer:
[tex] - 2(4x + 4) - 3x - 2 = 34 \\ \\ - 8x - 8 - 3x - 2 = 34 \\ \\ - 8x - 3x = 34 + 8 + 2 \\ \\ - 11x = 34 + 8 + 2 \\ \\ - 11x = 44 \\ \\ x = - \frac{44}{11} \\ \\ x = - 4[/tex]
Answer:
[tex]−2(4x+4) - 3x - 2 = 34 \\ - 8x - 8 - 3x - 2 = 34 \\ - 11x - 10 = 34 \\ - 11x = 34 + 10 \\ - 11x = 44 \\ \frac{ - 11x}{ - 11} = \frac{ - 44}{ - 11} \\ x = -4 [/tex]

write an expression to represent the surface area of a cylinder with a height twice as long as its radius
Answer:
area = 2 π r 2 + 2 π r h
Step-by-step explanation:
The two circles that make up the ends of the cylinder.
The side of the cylinder, which when "unrolled" is a rectangle
π is Pi, approximately 3.142
r is the radius of the cylinder
h height of the cylinder
The two circles that make up the ends of the cylinder.
The side of the cylinder, which when "unrolled" is a rectangle
Pi (π) approximately 3.142
radius (r) of the cylinder
the height (h) of the cylinder
therefore your answer is
area = 2 π r 2 + 2 π r h
the measure of the angles of a triangle are shown in the figure below. solve for x.
Answer:
[tex]\boxed {\boxed {\sf x= 12}}[/tex]
Step-by-step explanation:
We are asked to solve for x. We are given a triangle and all 3 angles are labeled. We know that the sum of the angles in a triangle must be 180 degrees. Therefore, the given angles: 81, 57, and (2x+18) must add to 180. We can set up an equation.
[tex]81+57+ (2x+18)= 180[/tex]
Now we can solve for x. Begin by combing like terms on the left side of the equation. All the constants (terms without a variable) can be added.
[tex](81+57+18)+2x=180[/tex]
[tex]156+2x=180[/tex]
We will solve for x by isolating it. 156 is being added to 2x. The inverse operation of addition is subtraction. Subtract 156 from both sides of the equation.
[tex]156-156+2x=180-156 \\2x=180-156 \\2x= 24[/tex]
x is being multiplied by 2. The inverse operation of multiplication is division. Divide both sides by 2.
[tex]2x/2= 24/2 \\x= 24/2 \\x=12[/tex]
In this triangle, x is equal to 12.
Answer:
x° = 12°Step-by-step explanation:
❁ Hello! ❁
The sum of the measures of the angles of a triangle is 180°.
81° + 57° + (2x + 18)° = 180°
138° + (2x + 18)° = 180°
(2x + 18)° + 138° = 180°
2x + 18° = 180° - 138°
2x + 18° = 42°
2x = 42° - 18°
2x = 24°
x° = 24° ÷ 2
x° = 12°
Success! ☺️
