Which one of the following equations represents a circle with its center of origin?
A) x^2 + y^2 = 5
B) x^2 + y = 25
C) x + y = 5
D) x/2 + y/2 = 25
Answer:
A) x² + y² = 5Step-by-step explanation:
The equation of the circle:
(x - h)² + (y - k)² = r²The center is (h, k)
Wen the center is the origin we have, h = 0, k = 0:
x² + y² = r²The only equation in same format is the first one

Which table represents a linear function?
At a glance, Kendra believes that the function represented on the graph is linear.
How can Kendra determine if the function is actually linear?
She can check to see if the rate of vertical increase equals the rate of horizontal increase between each pair of points.
She can check to see if the sum of each y-value and x-value in every ordered pair is the same.
She can check to see if the quotient of each y-value and x-value in every ordered pair is the same.
She can check to see if the rate of change between the first two ordered pairs is the same as the rate of change between the first and last ordered pairs.
29. The circumference of a circle is C centimeters. The diameter of the circle is 13
centimeters.
Which expression best represents the value of ar?
Answer:If the diameter is 13 you should try each answer until you find pi.
To find pi you have to divide the circumference by the radius.
You don't need to find the circumference in this question but you can.
The circumference is 40.82
Then you have to divide
40.82÷13
that equals 3.14
and because that is pi, C is your answer

hi, i need help with Solve 18>12+x. Graph the solution.
Answer:
x < 6
Step-by-step explanation:
18 > 12 + x
Switch sides:
12 + x < 18
Subtract 12 from both sides:
12 + x - 12 < 18 - 12
x < 6
The solution of the inequality is,
⇒ x < 6
And, Graph is shown in image.
What is mean by Inequality?A relation by which we can compare two or more mathematical expression is called an inequality.
Given that;
The inequality is,
⇒ 18 > 12 + x
Now, We can solve the inequality as;
⇒ 18 > 12 + x
Switch sides:
⇒ 12 + x < 18
Subtract 12 from both sides:
⇒ 12 + x - 12 < 18 - 12
⇒ x < 6
Thus, The solution of the inequality is,
⇒ x < 6

Erica wanted to conduct a survey to find the most popular ice cream flavor sold at the local ice cream shop. She decided to survey all the girls present in the shop. Is this sample representative of the population?
A. Yes, it asks all the girls present in the shop
B. Yes, the sample is restricted within the shop
C. No, the sample is only about ice cream flavors
D. No, it asks only the girls in the shop
Answer:
D
Step-by-step explanation:
Answer: D. No, it asks only the girls in the shop
Erica's survey leaves out the boys which means the boys are completely under-represented while the girls are over-represented. The population consists of boys and girls. This means the sample needs to have the same proportional mix of those genders (ie around 50% for each) if you want the sample to be representative of the population.

The value of a bank account, B, after x years is represented by the equation B = 1000(1+.014)x. To the nearest penny, how much is the account worth after 15 years?
Answer:
1232 penny
Step-by-step explanation:
Given the value of a bank account, B, after x years is represented by the equation B = 1000(1+.014)^x.
To determine the account worth after 15 years, we will substitute x = 15 into the expression as shown;
B = 1000(1+.014)^x.
B = 1000(1+.014)^15
B = 1000(1.014)^15
B = 1000(1.2319)
B = 1231.9penny
Hence the value after 15years is 1232 penny (to the nearest penny)

Answer:
Required amount of aluminium foil = 522.80 [tex]in^{2}[/tex]
Step-by-step explanation:
The shape of the large Hershey kisses can be compared to that of a cone. So that;
the surface area of the kisses = [tex]\pi[/tex][tex]r^{2}[/tex] + [tex]\pi[/tex]rl
Let the slant height be represented by l. Applying the Pythagoras theorem;
[tex]l^{2}[/tex] = [tex]10^{2}[/tex] + [tex]8^{2}[/tex]
= 100 + 64
= 164
l = [tex]\sqrt{164}[/tex]
l = 12.81 in
Thus,
surface area of the kisses = (3.14 x [tex]8^{2}[/tex]) + (3.14 x 8 x 12.81)
= 200.96 + 321.7872
= 522.7472
surface area of the kisses = 522.75 [tex]in^{2}[/tex]
Thus, the amount of aluminium foil required to wrap the kisses is 522.80 [tex]in^{2}[/tex].
A Rectangular has area 12a^2 and perimeter 14a what are the dimensions of this Rectangular?
9514 1404 393
Answer:
3a by 4a
Step-by-step explanation:
For dimensions L and W, the area and perimeter are ...
A = LW = 12a^2
P = 2(L+W) = 14a
Using the second equation, we can find L:
L +W = 7a . . . . . divide by 2
L = 7a -W
Substituting into the area formula gives the quadratic ...
(7a -W)(W) = 12a^2
W^2 -7aW +12a^2 = 0 . . . . arrange in standard form
(W -3a)(W -4a) = 0 . . . . . . . factor (find factors of 12 that total 7)
Then we have the two solutions ...
W = 3a, L = 4a
W = 4a, L = 3a
The rectangle dimensions are 3a by 4a.
Find the inequality represented by the graph
Answer:
y > -2/3 x + 3
Step-by-step explanation:
First we find the equation of the dashed line.
y = mx + b
We see b = 3.
The slope is -2/3.
The equation of the line is
y = -2/3 x + 3
The line is dashed, not solid, and the shading is above the line, so the inequality is
y > -2/3 x + 3
