The question requires us to simplify 8(y + 12) using the distributive property, which results in 8y + 96. So, correct answer is D: 8y + 96.
Explanation:The question is asking us to simplify the expression 8( y + 12)
using the distributive property. The distributive property states that multiplication distributes over addition. In simpler terms, it means that if you have a multiplication operation involving a sum (or difference), you can 'distribute' the multiplier to each term inside the parenthesis.
Applying the distributive property to 8( y + 12) gives us:
8 * y + 8 * 12
This simplifies to:
8y + 96
So the correct answer is D : 8y + 96.

Area of a circle: A = πr2
Answer: [tex]78.5\ cm^2[/tex]
Step-by-step explanation:
From the given we can see that there is a rectangle is rotated about a line bisecting its length in segment of 5 cm in each.
Since the base will be a circle, then the area of the base will be :-
[tex]\text{Area of base}=\pi r^2\\\\\\\Rightarrow\text{Area of base}=3.14\times(5)^2\\\\\\\Rightarrow\text{Area of base}=78.5\ cm^2[/tex]

Given line L = ax + by + c = 0, b 0 What is the x-intercept? y-intercept?
Answer:
On Odyssey ware it is -c/a
Step-by-step explanation:
The x-intercept and the y-intercept of a line can be found by setting y and x to zero in the line equation respectively. The x-intercept is -c/a and the y-intercept is -c/b.
Explanation:To find the x and y-intercepts of the given line equation L = ax + by + c = 0, we must set one variable to zero and solve for the other.
To find the x-intercept of a line, we can set y to zero (as this is the case when the line crosses the x-axis), we get:
L = ax + b(0) + c = 0 or x = -c/a
Therefore the getX-intercept of the line is -c/a.
Similarly to find the y-intercept of the line equation, we can set x to zero (as this is the case when the line crosses the y-axis), we get:
L = a(0) + by + c = 0 or y = -c/b
Hence, the y-intercept of the line is -c/b.

What is the midpoint of the x-intercepts of
f(x) = (x – 4)(x + 4)?
Answer:
midpoint is (0,0)
Step-by-step explanation:
the midpoint of the x-intercepts of
[tex]f(x) = (x - 4)(x + 4)[/tex]
To find the midpoint of x intercepts, we need to find the x intercepts first
we find x intercepts by replacing f(x) with 0
[tex]0 = (x - 4)(x + 4)[/tex]
Set each factor =0 and solve for x
[tex]x-4=0 , x=4[/tex]
[tex]x+4=0, x=-4[/tex]
X intercepts are -4 and 4
Midpoint of -4 and 4 is [tex]\frac{-4+4}{2} =0[/tex]
X intercepts lies on x axis . So midpoint is (0,0)
A boat traveled downstream a distance of 80 mi and then came right back. If the speed of the current was 7 mph and the total trip took 3 hours and 20 minutes, find the average speed of the boat relative to the water.
By converting the total trip time to minutes, using the formula for speed (distance/time), and using a system of equations representing the total trip speed when the boat is moving downstream and upstream, we can find the average speed of the boat relative to the water.
Explanation:To solve this problem, we first need to convert the total trip time to minutes to make calculations easier. Given in the problem, 3 hours 20 minutes equates to 200 minutes. Next, we should use the formula for speed, which is distance divided by time. We know that the total distance traveled by the boat is 80 miles downstream and 80 miles back, totaling 160 miles.
When moving downstream, the speed of the boat and the speed of the current both aid in the boat’s motion. Thus we have speed of the boat = speed of the boat in still water + speed of the current. However, when the boat is moving upstream, the speed of the current works against the boat's motion. Thus we have speed of the boat = speed of the boat in still water - speed of the current.
By using the system of these equations and the fact that total time equals total distance divided by the speed of the boat, we can find the speed of the boat in still water, which represents the average speed of the boat relative to the water.

What is arithmetic mean?
Arithmetic mean is defined as the ratio of the sum of observations to the total number of observations. It can be referred to as the average of a specific set of data or the arithmetic mean. One of the basic methods used to acquire a result, the term "Mean" is commonly used in the field of statistics.
The formula for the mean of a given set of data is as follows:
Mean = Sum of Observations/Total number of observations
Given the frequency distribution as :
Household size (x) Frequency (f) fx
1 2 1 × 2 = 2
2 4 2 × 4 = 8
3 6 3 × 6 = 18
4 5 4 × 5 = 20
5 2 5 × 2 = 10
Summation of fx = (Σfx) = 2 + 8 + 18 + 20 + 10 = 58
Total frequency = (Σf) = 2 + 4 + 6 + 5 + 2 = 19
⇒ Mean = Σfx/Σf
⇒ 58/ 19
⇒ 3.1
Thus, the mean of the frequency distribution is 3.1.

Does this set of ordered pairs represent a function?
{(–5, –5), (–1, –2), (0, –2), (3, 7), (8, 9)}
Answer:
Option C is correct
Yes, the set of ordered pairs {(–5, –5), (–1, –2), (0, –2), (3, 7), (8, 9)} represents the function.
because every x-value corresponds to exactly one y-value.
Step-by-step explanation:
A function states that it is a relation in which every domain value is paired with exactly one element of range.
Given the set of ordered pair:
{(–5, –5), (–1, –2), (0, –2), (3, 7), (8, 9)}
Domain is all the x-values, and range is all the y-values.
Domain: {-5, -1, 0, 3, 8}
Range: {-5, -2, -2, 7, 9}
By definition:
each input value (i.e x values) is paired with exactly one element of y-value.
therefore,the set of ordered pairs {(–5, –5), (–1, –2), (0, –2), (3, 7), (8, 9)} represents the function.
Which of the following functions has the greatest y-intercept?

−2 −6
−1 −2
0 3
1 5
2 6
or g(x) = 3 cos(2x) + 1
please include explanation
Answer:
g(x) has greatest y-intercept.
Step-by-step explanation:
We are given a table of values for function f(x) as:
x y=f(x)
−3 −14
−2 −6
−1 −2
0 3
1 5
2 6
We know that the y-intercept of a function is a point where the x-value is zero.
i.e. the input value is zero.
Hence, after looking at the table of values of the function f(x) we have the y-intercept of the function f(x) is:
y=3
Also we are given function g(x) as:
g(x) = 3 cos(2x) + 1
Hence, we calculate the y-intercept of the function g(x) by taking x=0
on taking x=0 we have:
g(0)=3 cos(0)+1
g(0)=3+1=4
Hence, the y-intercept of function g(x) is 4.
Hence, g(x) has the greatest y-intercept.

If a coin is tossed 4 times, and then a standard six-sided die is rolled 2 times, and finally a group of four cards are drawn from a standard deck of 52 cards without replacement, how many different outcomes are possible?
[tex]\(1138368400\)[/tex] different outcomes possible when considering all the events together.
Coin Toss: Since each toss is independent of the others, the total number of outcomes for 4 tosses is:
[tex]\(2 \times 2 \times 2 \times 2 = 2^4 = 16\)[/tex].
Die Roll: A standard six-sided die has 6 faces, each with a different number from 1 to 6. When the die is rolled once, there are 6 possible outcomes. If the die is rolled 2 times, the number of different outcomes is:
[tex]\(6 \times 6 = 6^2 = 36\)[/tex]
Card Draw: When drawing a card from the deck, there are 52 possible outcomes. If a second card is drawn without replacing the first, there are now 51 possible outcomes for the second card (since one card has already been drawn). Continuing this pattern, for the third card, there are 50 possible outcomes, and for the fourth card, there are 49 possible outcomes.
The number of different outcomes for drawing 4 cards without replacement is: [tex]\(52 \times 51 \times 50 \times 49\)[/tex].
[tex]\[ \text{Total Outcomes} = (\text{Coin Toss Outcomes}) \times (\text{Die Roll Outcomes}) \times (\text{Card Draw Outcomes}) \][/tex]
[tex]\[ \text{Total Outcomes} = 16 \times 36 \times (52 \times 51 \times 50 \times 49) \][/tex]
[tex]\[ \text{Total Outcomes} = 6^2 \times 52 \times 51 \times 50 \times 49 \][/tex]
[tex]\[ \text{Total Outcomes} = 36 \times 52 \times 51 \times 50 \times 49 \][/tex]
