Answer:
Step-by-step explanation:
Domain is indicative of the x values,while range is the y values. For our relation, the domain will be
D = {2, 3, 4} and the range will be
R = {8, 27, 64}
Assume that y varies inversely with x. If y = 4 when x = 6, find y when x = 2
Answer:
y = 12
Step-by-step explanation:
Given y varies inversely with x then the equation relating them is
y = [tex]\frac{k}{x}[/tex] ← k is the constant of variation
To find k use the condition y = 4 when x = 6, then
4 = [tex]\frac{k}{6}[/tex] ( multiply both sides by 6 )
24 = k
y = [tex]\frac{24}{x}[/tex] ← equation of variation
When x = 2 , then
y = [tex]\frac{24}{2}[/tex] = 12

hey guys i have everything caught up but in science i have a 96 but a missing project. projects a worth 80 percent of your grade will i still pass? today’s the last day
Answer:
No
Step-by-step explanation:
Technically, if you didn't turn anything in then no. If it is truly 80% of your final grade then not turning anything in would drop your grade to an F immediately. Although for a single project to be worth 80% of the entire year's grade seems off. Usually, finals and projects are a large percentage, but are more around the 25% range and not 80%. Otherwise, a student could not do anything the entire year and simply do the project and still pass with a B. That is why the grading system is not usually designed like this.
whats this picture's eqeuation
Answer:
y = 2x + 3
Step-by-step explanation:
The slope can be found by taking two points, for instance: (0,3) and (3,9) which lie on the graph. Find the slope between the two, remember rise over run:
(9-3)/(3-0) = 6/3 = 2
The y-intercept is (0,3)
So b in the y= mx + b equation is 3.
m is the slope, so it is 2.
y = 2x + 3

angle c = ___ degrees
Angle D = ABC arc / 2
x + 100 = ABC arc / 2
ABC arc = 2 × ( x + 100 )
ABC arc = 2x + 200 ( ♡ )
_________________________________
Angle B = ADC arc / 2
3x = ADC arc / 2
ADC arc = 2 × 3x
ADC arc = 6x ( ☆ )
_________________________________
ABC arc + ADC arc = 360
( ♡ ) , ( ☆ ) :
( 2x + 200 ) + ( 6x ) = 360
8x + 200 = 360
8x = 360 - 200
8x = 160
x = 160/8
x = 20
____________________________
Thus :
Angle A = 5(20) - 3 = 97 degrees
Angle B = 3(20) = 60 degrees
Angle D = 20 + 100 = 120 degrees
____________________________
Sum of the interior angles of any four-sides figures are equal 360 degrees ,
Thus :
Angle A+Angle B+Angle C+Angle D = 360
97 + 60 + Angle C + 120 = 360
Angle C + 120 + 157 = 360
Angle C + 277 = 360
Angle C = 360 - 270 - 7
Angle C = 90 - 7
Angle C = 83 degrees

In the design shown below, four semicircles are attached to a square whose area is 36 square centimeters. Which of the following is closest to the total area of the shaded semicircles, measured in square centimeters?
Answer:
56.549 cm (choice 1)
Step-by-step explanation:
If the area of the square if 36 cm, then each side is 6 cm.
That means the diameter for each semi circle is also 6 cm.
Formula for a semi circle is 1/2(πr²)
We need the radius, which is half the diameter. So the radius is 6÷2= 3
Now plug in to the formula.
A= 1/2(π3²)
A= 14.137 (nearest hundredths)
Now multiply that by 4, because there are 4 semi circles
4(14.137)= 56.549 cm (nearest hundredths)
Uhm can you answer it and tell me how you did it? I'm like dead confused
Answer:
Hello! answer:
rectangle a: 8
rectangle b: 24
figure: 32
Step-by-step explanation:
Hello I'll show a demonstration, with a picture and explanation. Ok so as shown in the picture i circled the base and height those are basically what you have to multiply to find the area.
we are given the height for rectangle a but not the base so we have to find it we know the base at the bottom for the whole thing is 5 and the base for B is. 3 so we can just subtract 3 from 5 to find A's base so... 5 - 3 = 2
now we have everything we need to find the area so....
4 × 2 = 8 so rectangle a is 8
3 × 8 = 24 so rectangle b is 24
then for the whole figure we can just add those two up for the entire area so...
24 + 8 = 32 therefore the figures area is 32 Hope that helps!

Hope it is helpful....The area of a circle is 161 in. What is the radius?
Answer:
Approximately 7.16 in
Step-by-step explanation:
Hi there!
Area of a circle equation: [tex]A=\pi r^2[/tex] where r is the radius
Plug in the given area 161 in.²
[tex]161=\pi r^2[/tex]
Divide both sides by π to isolate r²
[tex]\frac{161}{\pi} =\frac{\pi r^2}{\pi} \\\frac{161}{\pi} =r^2[/tex]
Take the square root of both sides to isolate r
[tex]=r^2\\\sqrt{\frac{161}{\pi}} =r\\7.16=r[/tex]
Therefore, the radius of the circle is approximately 7.16 in.
I hope this helps!

PLEASE HELP I DONT KNOW HOW TO DO IT PLEASEEEE
Answer:
76
Step-by-step explanation:
so the sequence(pattern) is it increases by 5
there are 2 ways to solve this promblem
one count on your toes and hands by 5 starting at one until u get to 10 fingers and 5 toes. soon the promblems will get harder and you cant do that
other way multiply 5 by 15 and add it to 1
t( 15 ) = t( 1 ) + [ 14 × ( Constant value ) ]
________________________________
t( 1 ) = 1
&
Constant value = t( 2 ) - t( 1 ) = t( 3 ) - t( 2 )
Constant value = 6 - 1
Constant value = 5
________________________________
Thus :
t ( 15 ) = 1 + [ 14 × 5 ]
t( 15 ) = 1 + 70
t( 15 ) = 71
Need urgent help please, honest answers will get brainliest
Answer: Refer to the screenshot below
I've filled in the boxes with the proper answers
====================================================
Explanation for problem 1
In line 1, I used the distributive rule a*(b+c) = a*b+a*c. On the left side the 3(n+2) becomes 3n+6. On the right side, the 9(6-n) becomes 54-9n
On the next line, I added 9n to both sides. The 3n on the left side updates to 3n+9n = 12n.
For the third line, I subtracted 6 from both sides. Then the last line involves dividing both sides by 12 to fully isolate n. To confirm the solution n = 4, plug it back into the original equation. You should get the same thing on both sides after simplifying.
------------------------------------
Explanation for problem 2
The steps here are similar as problem 1, but this time we're involving fractions. Unfortunately, these steps don't involve clearing out the fractions which is often a handy trick to use.
We use the distributive rule on line 1
For line 2, we subtract 2m/9 from both sides. Think of 2m/3 as 6m/9 to help combine the fractions. The denominators must be the same for you to be able to add or subtract fractions.
For line 3, we subtract 4/3 from both sides. Think of 4/3 as 12/9.
The last step is to multiply both sides by 9/4, which is the reciprocal of 4/9. Your teacher made a typo on the right hand side of the last line. It should read [tex]\frac{4}{9}m[/tex] and not [tex]\frac{2}{9}m[/tex]. Refer to the previous line.
what is the y-intercept for 3x^2 + 2x - 1
Answer:
y- intercept = - 1
Step-by-step explanation:
To find the y- intercept , let x = 0 in the equation and evaluate for y
y = 3(0)² + 2(0) - 1 = 0 + 0 - 1 = - 1
y- intercept = - 1 or (0, - 1) in coordinate form
Answer:
Plug x=0 into the equation and solve the resulting equation
The y-intercept:
3x^2 + 2x - 1
3(0)^2 + 2x(0)- 1
0+0-1
-1
y=−1 is intercept for y

whats the average rate of change of h over the interval 5 ≤ t ≤ 9?
Given:
The graph of a function.
To find:
The average rate of change of h over the interval [tex]5\leq t\leq 9[/tex].
Solution:
The average rate of change of a function f(x) over the interval [a,b] is:
[tex]m=\dfrac{f(x_2)-f(x_1)}{x_2-x_1}[/tex]
So, the average rate of change of h over the interval [tex]5\leq t\leq 9[/tex] is:
[tex]m=\dfrac{h(9)-h(5)}{9-5}[/tex]
From the given graph it is clear that [tex]h(9)=7,h(5)=3[/tex]. Substituting these values, we get
[tex]m=\dfrac{7-3}{9-5}[/tex]
[tex]m=\dfrac{4}{4}[/tex]
[tex]m=1[/tex]
Therefore, the average rate of change of h over the interval [tex]5\leq t\leq 9[/tex] is 1.
