Answer:
D. 2(√34 + √106)
Step-by-step explanation:
1) Find the hypotenuse of a larger triangle infused in the kite since perimeter means the boundary of a shape. To do so, we need to apply the Pythagoras Theorem.
c² = a² + b²
c² = 5² + 9²
c² = 25 + 81
c² = 106
c = √106
2) Find the hypotenuse of the a smaller triangle infused in the kite.
c² = a² + b²
c² = 3² + 5²
c² = 9 + 25
c² = 34
c = √34
3) Apply the the formula for the perimeter of a kite; 2(a + b), where a is the smaller triangle and b is the larger triangle or vice versa.
= 2(√34 + √106)

If the last 2 months of the year each have the most common amount of rainfall, how much more rain will fall for the year?
Answer:
Step-by-step explanation:
The table shows the amount of rainfall recorded over the first 10 months of a year. Draw a line plot, if needed.
Amount of Rainfall (inches)
Part A
What is the difference between the greatest and least amounts of rainfall in a month?
Let x = the unknown.
Greatest amount= 3 1/4
Least amount = 3/4
x= 3 1/4 - 3/4 = 2 1/2 inches.
Part B
If the last 2 months of the year each have the most common amount of rainfall, how much more rain will fall for the year?
The number with the most common amount is 2 3/4.
2 3/4 + 2 3/4 = 5 1/2 inches.

Thirty adults were asked how many pets they have had over their lifetime. the results are shown in the histogram below. a bar graph entitled lifetime pets has number of pets on the x-axis and number of adults on the y-axis. 14 adults had 1-5 pets; 9 had 6 to 10; 5 had 11 to 15; 2 had 16 to 20. which of the following is most likely true? the mean and median are both in the interval 1–5. the mean and median are both in the interval 6–10. the mean is in the interval 6–10, and the median is in the interval 1–5. the mean is in the interval 1–5, and the median is in the interval 6–10.
Using the concepts of the mean and of the median, it is found that the correct option is given by:
both in the interval 6–10.
What are the mean and the median of the data-set?The mean is the sum of all observations divided by the number of observations.The median is the measure that separates the bottom half of the variable from the upper half, that is, the 50th percentile.To calculate the mean from the histogram, we take the midpoint of each interval and calculate the weighed mean, hence:
[tex]M = \frac{14(3) + 9(8) + 5(13) + 2(18)}{30} = 7.17[/tex]
The median is in the interval in which the 30/2 = 15th measure is, which is also in the interval 6-10, as the interval 1-5 had 14 adults, and after interval 6-10, there are 23 adults.
Hence, the correct option is given by:
both in the interval 6–10.

The foci and the vertices of the hyperbola are labeled.
Which equation represents the hyperbola shown in the graph?
Answer is B
The answer is B and pls mark me brainiest
The equation of the hyperbola is:
(x - 3)² / 9 - (y - 2)² / 16 = 1.
To find the equation of the hyperbola with the given foci and vertices, we need to determine the center, semi-major axis (a), and semi-minor axis (b) of the hyperbola.
The center of the hyperbola is the midpoint between the two vertices:
Center = ((3 + 3) / 2, (5 + (-1)) / 2) = (3, 2).
The distance between the center and one of the vertices gives us the semi-major axis (a):
a = distance between center and vertex = 5 - 2 = 3.
The distance between the center and one of the foci gives us the distance c (the distance from the center to the focus):
c = distance between center and focus = 7 - 2 = 5.
Now, we can find the value of b (the semi-minor axis) using the relationship between a, b, and c in a hyperbola:
c² = a² + b²
5² = 3² + b²
25 = 9 + b²
b² = 25 - 9
b² = 16
b = 4.
Now that we have the center (h, k) = (3, 2), the semi-major axis (a) = 3, and the semi-minor axis (b) = 4, we can write the equation of the hyperbola in standard form:
For a hyperbola (center at (h, k)), the equation is:
(x - h)² / a² - (y - k)² / b² = 1.
Plugging in the values:
(x - 3)² / 3² - (y - 2)² / 4² = 1.
The equation of the hyperbola is:
(x - 3)² / 9 - (y - 2)² / 16 = 1.

Answer:
-7?
Step-by-step explanation:
I mean, is the question 20 - 27 =? Or it's something else? Lol.
20 - 27 = -7, it's very straightforward cannot write it in more detailed way. When we substract a number from another and the first one is smaller the result is a negative number. Imagine someone sells up to 3 apples, you ask him to give you 5. He gives you all 3 of his so he has 0 but you force him to go and get another 2 for you. He lost another 2, so he has less than 0 now. He has -2 apples: 3 - 5 = -2.

If p → q is true, then ~ p → ~ q is __________ true.
Sometimes
Always
Never
Answer:
1. If p is true and q is false, the p -> q is never true.
2. When p is false and q is true, then p or q is always true.
3. If p is true and ~ q is false, then p -> ~ q
N
is never false.
4. If p is true and q is true, then ~ p -> ~ q is always true.
5. If p->q is true and q is true, then p is
always true.
Further Explanation:
The logic gates are used here.
Here, the symbol -> is for implication. Implication p-> q means that if p is true then q must be true.
So let us look at all the questions one by one.
1. p is true and q is false, the p -> q is always, sometimes, never true.
p-> q
true -> false
The true should imply true so the given statement will never be true.
2. When p is false and q is true, then p or q is always, sometimes, never true.
false or true
We know that in or gate even if one input is true, the whole output is true. So this statement will be always true given p is false and q is true.
3. If p is true and~q is false, then P q is always, sometimes, never false.
This translates to:
true -> true
So it will never be false.
4. If p is true and q is true, then ^p -> ~q is always, sometimes, never true.
This translates to:
false false
This will always be true.
5. If p->q is true and q is true, then p is always, sometimes, never true.
If p->q is true and q is true then will always be true. "Implies to" states that in p->q, in order for q to be true p has to be true. So p will always be true.
Which model best represents the data set? exponential, because there is a relatively consistent multiplicative rate of change exponential, because there is a relatively consistent additive rate of change linear, because there is a relatively consistent multiplicative rate of change linear, because there is a relatively consistent additive rate of change
The first choice, is exponential, because there is a relatively consistent multiplicative rate of change.
What is exponential?An exponential function is a function whose value is a constant raised to the power of an argument
1) I have attached the figure with the data table that represents the temperature of a cup of coffee over time.
These are the data:
Time (min) ------ Temperature (°F)
0 ----------------------- 200
10 ---------------------- 180
20 --------------------- 163
30 --------------------- 146
40 ---------------------131
50 -------------------- 118
60 -------------------- 107
2) Since, the increase in time is constant, while the decrease in temperaute is not, you know that it is not linear.
3) The other two options involve exponential models.
The exponential models have a constant multiplicative rate of change, not additive. Therefore, the only feasible choice is the first one: temperature of a cup of coffee over time.
4) You can prove it:
i) Exponential models have the general form y = A [r]ˣ, where B is r is the multiplicative rate of change: any value is equal to the prior value multiplied by r:
y₁ = A [r]¹
y₂ = A[r]²
y₂ / y1 = r ← as you see this is the constant multiplicative rate of change.
ii) Test some data:
180 / 200 = 0.9
163 / 180 ≈ 0.906 ≈ 0.9
146 / 163 ≈ 0.896 ≈ 0.9
131 / 146 ≈ 0.897 ≈ 0.9
118 / 131 ≈ 0.901 ≈ 0.9
107 / 118 ≈ 0.907 ≈ 0.9
As you see all the data of the table have a relatively consistent multiplicative rate of change, which proves that the temperature follows an exponential decay; so the right choice is the first one.

Which of the following is the surface area of the right cylinder below? A. 244π units B. 204π units C.869π units D.352π units
Answer is: D. 352 pi ✅
Why is that the case? Let's see.
When finding surface area, multiply two times pi times the radius times the height.
[tex]A = 2\pi rh+2\pi r^2[/tex]
Now, you need to split these four values into an actual equation.
2 followed by pi radius-height plus two pi radius, is actually the formula for surface added to the formula of area, so;
[tex]2\pi rh+2\pi r^2 = 2 * \pi * 8(radius) * 14 + 2(height~plus~the~two) * \pi * 8^2[/tex]
Solve.
the result is 1105 according to order of operations.
Divide 1105 by pi to get the answer. Pi is 3.14... so for every 3.14..., you count that as one.
[tex]1105 / 3.14 = 351.91...[/tex] which rounds to 352
Therefore, your answer is 352π units²
