Identify one radii, one diameter, and one chord of the circle. Justify your answers.
Answer:
Chord: RT (and RS and TU, but those are also diameters)
Diameter: RS or TU
Radii: OU, OS, OT, or OR
Step-by-step explanation:
Chord: A line segment joining two points on a curve. Doesn't have to cross the center. (AKA, they have to touch the outer edge of the circle.)
Diameter: Chord that crosses the center of the circle(All examples given above cross center O)
Radius: Line segment that goes from the center of a circle to an endpoint that lies on the circle.

what is 8 to the power of 3
Answer:
512
Step-by-step explanation:
8×8×8
=512
8³=512
Therefore 8 to the power of 3 is 512
Answer: 512
Step-by-step explanation: 8 to the power of 3 means the same as 8³.
The smaller 3 which is called the exponent tells us that we need to multiply the 8 three times. So we have 8 · 8 · 8 which simplifies to 512.
So 8³ is equal to 512.

similarities and differences between sine and cosine graphs — Algebra 2
The similarities between sine and cosine graphs are their amplitude and periodicity, while the differences are their starting positions and phase. Overall, the graphs are more similar than different.
Similarities:
The sine and cosine functions have the same amplitude, which is the maximum value of the wave.
Both functions are periodic, meaning they repeat their pattern infinitely.
Differences:
The sine function starts with an amplitude of zero, while the cosine function starts with an amplitude of one.
The sine and cosine functions are out of phase by 90 degrees, meaning they reach their maximum and minimum values at different times.
Overall, the graphs of the sine and cosine functions are more similar than different because they share the same amplitude and shape, but they differ in their starting positions and phase.

Evaluate f(3) for the piecewise function: f(x) = StartLayout enlarged left-brace 1st Row StartFraction 3 x Over 2 EndFraction + 8, x less-than negative 6 2nd row negative 3 x minus 2, negative 4, less-than-or-equal-to x less-than-or-equal-to 3 Third row 4 x + 4, x greater-than 3 EndLayout Which value represents f(3)? –11 8 12.5 16
Answer:
The answer is -11
Step-by-step explanation:
I just finished the assignment hope this helps!
To evaluate f(3) for the given piecewise function, we use the second part of the function, which applies when x is between -4 and 3, inclusive. By substituting 3 into this piece, we find that f(3) is -11.
To find the value of f(3) for the given piecewise function, we need to determine which piece of the function applies when x is equal to 3. The function is defined as follows:
For x < -6, f(x) =
3x/2 + 8
For -4 ≤ x ≤ 3, f(x) = -3x - 2
For x > 3, f(x) = 4x + 4
Since 3 is within the range of the second piece (-4 ≤ x ≤ 3), we calculate the value by substituting x with 3 in the second function part:
f(3) = -3(3) - 2 = -9 - 2 = -11.
Therefore, the value that represents f(3) is -11.

Suppose you invested $500 in K-Mart stock in October
of 2001. Each month the stock lost 2% of its value.
How much was the stock worth in October of 2002?
(HINT: The loss is per MONTH.)
Answer:
$380
Step-by-step explanation:
Amount invested in October 2001 = $500
If 2% is lost on stock each month, amount lost every month will be 2% of $500
= 2/100×$500
= $10
In order to know how much the stock will cost by October 2002, we need to know the number of month there is between October 2001 and October 2002.
The number of months within this period is 12months
If $10 is lost per month, the total stock lost for 12months will be
$10×12 = $120
Stock worth by October 2002 = Money invested - Total stock loss
Stock worth by October 2002 = $500-$120
= $380

A circular sidewalk with a radius of 100 meters is having a railing installed
along 120° of its arc. How many meters of railing will be needed? (HINT: arc
length).
A. 100pi/3 m
B. 200pi/3 m
C. 10pi/3 m
D. 2pi/3 m
Answer:
B
Step-by-step explanation:
Whole circle is 360 degrees.
The railing is 120 degrees.
That is:
120/360 = 1/3 rd of the whole length of the circle (perimeter).
We will find perimeter of the circle (a.k.a. Circumference) and then multiply it by (1/3) to get meters of railing needed.
First, circumference:
[tex]C=2\pi r\\C=2 \pi (100)\\C=200\pi\\C=628.32[/tex]
The railing is (1/3)rd of it, so:
[tex]\frac{1}{3}*628.32=209.44[/tex]
The railing is 209.44 meters.
The answer choices are in pi, so it will be:
[tex]\frac{1}{3}*200\pi=\frac{200\pi}{3}[/tex] meters
Answer choice B is right

A cone has a slant height of 26 inches and a diameter of 48 inches. What is the volume of the cone?
Answer:
Approx. 28952.92
Step-by-step explanation:
Because cone volume is found by V=πr²[tex]\frac{h}{3}[/tex].
First you find the radius. Because you have the diameter, you divide that by two, because it's 48, and diameter is radius multiplied by 2. So the radius is 24. 24pi squared with height divided by three is volume so, 28952.92.

What is a cone?It is a shape of a Christmas tree where there is a base of radius r and a top point called the apex.
The volume of a cone is 1/3πr²h.
We have,
Diameter = 48 inches
Radius = 24 inches
r = 24 inches
Slant height = 26 inches
L = 26 inches
L² = h² + r²
26² = h² + 24²
h² = 676 - 576
h² = 100
h = 10 inches
The volume of the cone.
= 1/3 x π x 24 x 24 x 10
= 3.14 x 8 x 24 x 10
= 6028.8 inches³
Thus,
The volume of the cone is 6028.8 inches³.

A circle with the equation (x + 4)2 + (y + 2)2 = 36 is reflected over the line x = 1. What is the equation of the image? (x + 4)2 + (y - 2)2 = 36 (x - 6)2 + (y + 2)2 = 36 (x + 6)2 + (y - 2)2 = 36 (x - 4)2 + (y + 2)2 = 36
Answer:
B
Step-by-step explanation:
Currently, the graph looks like the attachment.
The centre of this circle is at (-4, -2), but when we flip it over the line x = 1 (the blue line on the picture), the centre will become ((1- -4) + 1, -2) = (6, -2).
Look for the equation [tex](x-h)^2+(y-k)^2=r^2[/tex] that matches this center. We want the center (h, k) to be (6, -2), so our equation should look something like:
[tex](x-6)^2+(y+2)^2=36[/tex]
The answer is B.
Answer:
(x - 6)² + (y + 2)² = 36
Step-by-step explanation:
Centre before reflection: (-4,-2)
Centre after reflection:
(-4+5+5,-2) = (6,-2)
(x - 6)² + (y + 2)² = 36
A slide and its ladder form a right triangle with the ground, with the
slide representing the hypotenuse. The top of the ladder is 10 feet above
the ground, and the bottom of the ladder is 12 feet from the bottom of
the slide. What is the length of the slide to the nearest tenth of a foot?
Answer:
15.6 ft
Step-by-step explanation:
Let's call
a: distance from the top of the ladder to the ground = 10 ftb: distance from the bottom of the ladder to the bottom of the slide = 12 ftc: length of the slideFrom Pythagorean theorem:
c² = a² + b²
c = √(10² + 12²)
c = 15.6 ft
The length of the slide, which forms the hypotenuse of a right-angled triangle with the ground, is approximately 15.6 feet to the nearest tenth of a foot when calculated using the Pythagorean Theorem.
Explanation:The question involves finding the length of a slide (hypotenuse) when its ladder and the ground form a right-angled triangle. The top of the ladder is 10 feet above the ground (opposite side), and the bottom of the ladder is 12 feet away from the bottom of the slide (adjacent side). We will use the Pythagorean Theorem to solve for the slide's length, which is represented by the equation a² + b² = c², where a and b are the lengths of the legs of the triangle and c is the length of the hypotenuse.

How many groups of 100 can you take out of 941 when diving by 3?
Final answer:
When 941 is divided by 3, there are 313 groups of 3. To determine the number of groups of 100 that can be extracted, we divide 313 by 100, which results in 3 complete groups of 100 with 13 left over.
Explanation:
The question asks us to find out how many groups of 100 can be taken out of 941 when dividing by 3. First, we must divide 941 by 3 to understand this concept better:
941 ÷ 3 = 313 with a remainder of 2
Now, we know there are 313 groups of 3 in 941. However, the question asks for groups of 100. To find this, we can examine how many complete hundreds fit into the result of 313:
313 ÷ 100 = 3 with a remainder of 13
Therefore, 3 complete groups of 100 can be taken out when 941 is divided by 3, with 13 left over that cannot form another complete group of 100.
