¿What is a circle?.
Answer:
A circle is a shape.
Step-by-step explanation:
In geometry circles are known for you to solve the radius wit the formula A= π r^2
A circle is a shape consisting of all points in a plane that are a given distance from a given point, the centre; equivalently it is the curve traced out by a point that moves in a plane so that its distance from a given point is constant.
Which of the following correctly uses absolute value to show the distance between -80 and 15? (5 points)
a
|-80 - 15| = |-95| = -95 units

Can someone tell just the answer
Answer:
Option D is correct .
Step by step explanation:
A function is given to us and we need to find its inverse . The function is g(x) = -2x⁵ - 2.
So for finding its inverse , exachange x with y .
⇒ g(x) = -2x⁵ - 2 .
Let g(x) = y ,
⇒ y = -2x⁵ - 2 .
Replace x with y ,
⇒ x = -2y⁵ - 2
⇒ x + 2 = -2y⁵
⇒ y⁵ = x+2 / -2
⇒ y⁵ = (-1) ( x + 2) / (-1)(-2)
⇒ y⁵ = -x - 2/ 2
⇒ y = ⁵√ [ ( -x -2)/2 ]
Hence the inverse of the function is ,
[tex]\boxed{\red{\bf f^{-1}(x)=\sqrt[5]{\dfrac{-x-2}{2}}}}[/tex]
Hence the correct option is (D) .NEED HELP WITH THIS
Answer:
Step-by-step explanation:
think of this as a system of equations where the colors just represent a variable like x or y
I'll just arbitrarily set colors to some variable letter so we have
purple = x
green =y
blue =z
red = a
yellow = b
so we can now rewrite the 4 known equations of the system :)
Eq. 1) x+y = 13
Eq. 2) 2y+2z=18
Eq. 3) 2x+3y=31
Eq. 4) z + 4a = 12
Eq. 5) a * y = b
so solve the 1st eq for y => y =13-x then plug that into the 3rd eq and slove for x => 2x + 3(13-x) =31
2x + 39 -3x = 31
2x-3x = 31 - 39
-x = -8
x=8
plug 8 into Eq. 1 for x and solve for y
8+y = 13
y=5
plug y into Eq 1 and solve for z
2(5) +2z = 18
10 +2z = 18
2z = 8
z = 4
plug z into E1 4 and solve for a
4 + 4a = 12
4a = 8
a = 2
plug a and y into Eq 5 and solve b
2 * 5 = b
10=b
go to the drawing and plug in each of the color values that we put as variable letters above and get an A+ on your homework.. :)
Find m∠1.
help me answer this pls
Answer:
50 degrees
Step-by-step explanation:
Since the two lines are parallel, we know that the other angle above angle 1 is also 130, because corresponding angles are congruent. Next, since we know that it sits on a line, we know that angle 1 and 130 make a linear pair, or add up to 180 degrees. 180-130= angle 1. So angle 1 is 50 degrees. Sorry if the explanation is a bit funky.
According to the United States Census Bureau. Just about 5 1.5% of the adults in America are women. What would you say is the probability that the next adult you run into is female? What's the probability of that person being male?
Answer:
[tex]P(F) = 0.515[/tex]
[tex]P(M) = 0.485[/tex]
Step-by-step explanation:
Given
[tex]Female = 51.5\%[/tex]
Solving (a): Probability of running into a female
To do this, we simply convert the given proportion to decimal
[tex]P(F) = 51.5\%[/tex]
Convert to fraction
[tex]P(F) = \frac{51.5}{100}[/tex]
[tex]P(F) = 0.515[/tex]
Solving (b): Probability of running into a male
Represent this with [tex]P(M)[/tex]
To solve this, we apply the concept of probability complement which states that:
[tex]p + q = 1[/tex]
In this case:
[tex]P(F) + P(M) = 1[/tex]
Substitute 0.515 for P(F)
[tex]0.515 + P(M) = 1[/tex]
Subtract 0.515 from both sides
[tex]0.515-0.515 + P(M) = 1 - 0.515[/tex]
[tex]P(M) = 1 - 0.515[/tex]
[tex]P(M) = 0.485[/tex]
Find the perimeter??
Answer:
13 in
Step-by-step explanation:
just add all the numbers lol
Answer:
the perimeter of the triangle is 13[tex]in^{2}[/tex]
Step-by-step explanation:
All you have to do is add up all the sides together, but first we need to find a common denominator, and it can be 12
[tex]3\frac{1}{3}[/tex] = [tex]\frac{10}{3} = \frac{40}{12}[/tex] ( i multiplied them by 4 (numerator and denominator))
[tex]4\frac{1}{6} = \frac{25}{6} = \frac{50}{12}[/tex] ( i multiplied them by 2 (numerator and denominator))
[tex]5\frac{1}{2} = \frac{11}{2} = \frac{66}{12}[/tex] ( i multiplied them by 6 (numerator and denominator))
Now that you have a common denominator for all 3 fractions, you can now add them all up
[tex]\frac{40}{12} + \frac{50}{12} + \frac{66}{12}[/tex]
Now to add, the denominator has to stay the same (12), and add up all the numerators
[tex]\frac{40}{12} + \frac{50}{12} = \frac{90}{12} + \frac{66}{12} = \frac{156}{12} = 13 (simplified)[/tex]

Step-by-step explanation:
1. (0,9) (9,0) or (7,2) or (1,8)
2. m = rise/run = (0-9) / (9-0) = -1
3. y = mx + b for point (9,0)
y intercept ( b) = y - mx = 0 - (-1)*9 = 9
4. equation for trend line: y = -x + 9
check use (7,2): 2 = -7 + 9

Ji Sunn spent $24 at the local farmer’s market. She bought apples that cost $4 per pound and raspberries that cost $6 per pound. Which equation can be used to represent the amount of raspberries, r, in terms of apples, a?
r = 4 minus two-thirds a
r = 4 + two-thirds a
r = 6 minus three-halves a
r = 6 + three-halves aThe formula for electrical power is P = I V. Which is the equivalent equation solved for i?
A -yard-long field is divided into parts of equal length. Mr. Gump paints a 6-yard-long strip in each part. How long is the unpainted strip in each part of the field
Answer:
9 yards
Step-by-step explanation:
THE QUESTION ABOVE ISN'T COMPLETE THEN I FIND THE SAME QUESTION WITH JUST CHANGE IN VALUES. CHECK IT BELOW;
A 208-yard-long road is divided into 16 parts of equal length. Mr. Ward paints a 4-yard-long strip in each part. How long is the unpainted strip of each part of the road?
EXPLANATION:
From the question, a 208-yard-long road is been parted into into 16 parts and they all have equal length.
Then we can determine the Length of each part as
(208-yard-long road/16 parts )
= 13
Then each part has a length of 13 yards
From the question, we know that 4-yard-long strip was painted in each part by Mr. Ward. Which means to determine the
unpainted strip of each part, we are going to use the expresion below.
(Length of each strip - length of painted strip)
= (13 yards - 4-yard-long strip )
= 9 yards
Therefore, the length of unpainted strip of each part of the road is 9 yards

Answer:
122°
Step-by-step explanation:
10a + 2° + 5a - 2° = 180° [ being linear pair ]
15a = 180°
a = 180° / 15
a =12°
Now
<XYQ = 10a + 2° = 10 * 12° + 2° = 120° + 2° = 122°

If f(x)=2x and g(x) = x-4 what is the value of g(f(3)) ?
Answer:
The value of g(f(3)) = 2
Step-by-step explanation:
We are given:
[tex]f(x)=2x[/tex]
[tex]g(x) = x-4[/tex]
And we need to find g(f(3))
First we need to find g(f(x))
by putting the value of f(x) into g(x) i.e put x = 2x
[tex]g(x)=x-4\\g(f(x))=2x-4[/tex]
Now, we need to find g(f(3)) by putting x = 3 in g(f(x))
[tex]g(f(x))=2x-4\\Put\: x=3\\g(f(3))=2(3)-4\\g(f(3))=6-4\\g(f(3))=2[/tex]
So, the value of g(f(3)) = 2

Find the angle with the smallest measure in △ VUW. Name the angle using three letters
Answer:
∠VUW
Step-by-step explanation:
A triangle is a three sided polygon with three angles. Types of triangles are obtuse, scalene, isosceles, equilateral and so on.
In triangle VUW, since VU = WU, hence it is an isosceles triangle. In an isosceles triangle, two sides of the triangle are equal.
The size of an angle depends on its opposite side, the higher the opposite side the higher the angle. Since In triangle VUW, VU = 9, WU = 9, VW = 5. Since VW is the smallest side, the angle opposite to VW is the smallest angle.
Hence the smallest angle = ∠VUW
