What shape is created by the rotation and what is the approximate circumference of the base? Circumference of a circle: C = 2πr
Answer:
50inches
Step-by-step explanation:
Complete question;
The square shown(image attached) has a perimeter of 32 units. The square is rotated about line k. What shape is created by the rotation and what is the approximate circumference of the base? Circumference of a circle: C = 2πr a cone with a base circumference of about 25 units a cone with a base circumference of about 50 units a cylinder with a circumference of about 25 units a cylinder with a circumference of about 50 units.
The figure shown is a square
Perimeter of a square = 4L
L is the length of the side of the square
32 = 4L
L =32/4
L = 8units
Since the square is rotated about a line k forming a circular shapr, hence the radius of the circular shape is equal to the length of the side of the rotated square. Hence r = 8units
Get the circumference of the circle
C = 2πr
Substitute r = 8 into the formula
C = 2π(8)
C = 16π
C = 16(3.14)
C = 50.24in
Hence the approximate circumference of the circle is 50inches

Answer:
17.
78\sqrt{3},\ 39\sqrt{3},\ 78\sqrt{3}
19.
6,\ 12,\ 12\sqrt{2}
Step-by-step explanation:
The required values of the x, y, and z in the given triangle are 26√3, 13√3, and 39×√2 respectively.
If you know the lengths of two sides of a right triangle, you can use trigonometric ratios to calculate the measures of one (or both) of the acute angles.
Here,
For triangles,
sin45 = 39/x
z = 39×√2
xsin60 = 39×√2 cos45
x ×√3/2 = 39
x = 39 × 2 / √3
x = 26√3
Now,
cos60= y / x
1/2 = y / 26√3
y = 13√3
Thus, the required value of the x, y, and z in the given triangle are 26√3, 13√3, and 39×√2 respectively.

What is the
range of the function graphed below? ((Writing the answers in case you can’t read them well))
A. -infinity < y < 2
B. -2 < y < infinity
C. -infinity < y < -2
D. -infinity < y < infinity
Given:
The graph of a function.
To find:
The range of the graphed function.
Solution:
We know that, the domain is the set of x-values and range is the set of y-values values.
From the given graph it is clear that the functions is defined for all real values of x.
[tex]f(x)\to -\infty\text{ as }x\to -\infty[/tex]
[tex]f(x)\to 2\text{ as }x\to \infty[/tex]
The values of the function lie in the interval [tex]-\infty<y<2[/tex].
Range of the function [tex]=-\infty<y<2[/tex]
Therefore, the range of the graphed function is [tex]-\infty<y<2[/tex] and the correct option is A.

Answer:
33.
Step-by-step explanation:
33 = 3 * 11.
The number that is a product of two prime numbers is 33.
What are prime numbers?
Prime numbers are those numbers that do not have any factors other than one and the number itself.
Example:
2, 5, and 7 are all prime numbers.
We have,
5, 33, 27, 72, 36, 61, 81, 45
We will write the possible factors.
5
- 1 x 5
33
- 3 x 11
- 1 x 33
27
- 3 x 9
- 1 x 27
72
- 2 x 36
- 3 x 24
- 4 x 18

We see that,
33 is the only number that is a product of two prime numbers.
i.e
3 x 11 = 33
Thus,
33 is the number.

C x-int: 0.5. y-int: 1
D x-int: -0.5 y-int: -1
Answer:
I believe it would be B, very sorry if this didn't help!
Step-by-step explanation:
Answer: C x-int: 0.5. y-int: 1
Step-by-step explanation:
We first see the y-int of the graph, where x equal to 0.
Based on the graph, y is passed the y-axis on the positive sign, which means that y-int is (0,1), only b and c fits.
And we can clearly see the x-int is on the positive sign also, which is (0.5,0), c is the answer.

Alex got a iPhone 11 for Christmas as a present. After spending 3 hours on the iPhone Alex decided to walk down the stairs to get a snack in the kitchen, but then he fell down the stairs because he was paying attention to the iPhone. He heard a crack, but luckily it wasn't his iPhone 11. It was his spinal cord.
Compare the price between the iPhone 11 and spinal cord repairence.
(This question was on a question in math and it's kinda funny XD)
Answer:
The difference between iPhone 11 and Spinal cord repairence is 99,300$.
Step-by-step explanation:
To be honest, this is a really weird question. But a spinal cord injury can cost up to 100,000$ a year. And an iPhone 11 cost around 700$. It really just depends on what repairence the person got, but if I am wrong then I hope you the best with your question lol. And since Alex didnt break his phone, you wouldnt count the repairs for the iPhone 11.
