What angle maximizes the area of the triangle below?
Answer:
90°
Step-by-step explanation:
Area of triangle with sides a and b and included angle Θ:
A = (1/2)ab * sin Θ
dA/dx = (1/2)ab cos Θ
(1/2)ab cos Θ = 0
cos Θ = 0
Θ = 90°

Let f(x) = x + 2 and g(x) = x + 4.
Find f(g(f(2)).
Brainliest 15 points
Answer:
10
Step-by-step explanation:
Let's find f(2) first.
f(2) = 2 + 2 = 4
This means it would be f(g(4)).
Then let's find g(4).
g(4) = 4 + 4 = 8
Then, this means f(8).
f(8) = 8 + 2 = 10
Ms. Wall will roll two number cubes. What is
the probability that she will roll a sum of 9 ?
Express your answer as a fraction.
(I'll give brainlist if u get it right)
Answer: 9/1
Step-by-step explanation: Apologies for the mistake. Let's calculate the probability again.
To find the probability of rolling a sum of 9 on two number cubes, we need to determine the number of favorable outcomes and divide it by the total number of possible outcomes.
For a sum of 9, the following combinations are favorable:
(3, 6), (4, 5), (5, 4), (6, 3)
So, there are 4 favorable outcomes.
The total number of possible outcomes is still 6 × 6 = 36.
The probability of rolling a sum of 9 is:
Probability = Number of favorable outcomes / Total number of possible outcomes
Probability = 4 / 36
Simplifying the fraction, we get:
Probability = 1 / 9
Therefore, the probability of rolling a sum of 9 is 1/9, not 11/18 as previously stated.

Find the slope of the line passing through the points (6,6) and (6, -7).
slope: 1
Answer:
The line is a vertical line, which does not have a slope.
Step-by-step explanation:
Slope of a line:
Suppose we are given two points in the format (x,y) of a line. The slope is given by the change in y divided by the change in x.
(6,6) and (6, -7).
Change in y: -7 - 6 = -13
Change in x: 6 - 6 = 0
Slope is a division by 0, which means that the line is a vertical line, which does not have a slope.
ABC is translated 4 units to the left and 8 units up, then reflected across the y-axis. Answer the questions to find the coordinates of A after the transformations.
2. After the Translations, where is A located?
4. What are the coordinates of A after the reflection?
5. After the two transformations, has A returned to its original location?
9514 1404 393
Answer:
2. A'(3, 13)
4. A''(-3, 13)
5. No
Step-by-step explanation:
2. The translation is represented by the transformation ...
(x, y) ⇒ (x-4, y+8)
A(7, 5) ⇒ A'(7-4, 5+8) = A'(3, 13)
__
4. The reflection is represented by the transformation ...
(x, y) ⇒ (-x, y)
A'(3, 13) ⇒ A''(-3, 13)
__
5. No. The location (-3, 13) is not the same as the original location (7, 5).

Step-by-step explanation:
cube root 1331 : reciprocal of 0.2
give your answer in the form n:1
The cube root of 1331
(1331)^1/3 = 11
Reciprocal of 0.2 = 1 /0.2 = 5
Hence, the ratio Can be expressed as :

For positive numbers, square and square root are operations that preserve order. That is, the square of a larger number is larger than the square of a smaller number. Likewise, the square root of a larger number is larger than the square root of a smaller number. Here, ...
81 > 64 > 44 ⇔ √81 > √64 > √44.
If a number is not a perfect square (a number multiplied by itself), then its square root is irrational.
The size your dog and the number of times you take it to the vet, The amount your drive to school and the amount you have to pay for gas, The number of people at your party and the number of sodas you have in the refrigerator. What correlation are all of these separately. None, Positive, or Negative thanks so much and tell me which one thanks!
1. No correlation
Those things don't really relate to each other.
2. Positive correlation
The more you drive your car, the more you'll have to pay for gas.
3. Negative correlation

Answer:
[tex]C' = (2,8)[/tex]
[tex]A' = (4,4)[/tex]

Step-by-step explanation:
Given
[tex]k =2[/tex]
[tex]C =(1,4)[/tex]
[tex]A = (2,2)[/tex]
[tex]T =(5,5)[/tex]
Solving (a): The new points
To do this, we simply multiply the old points by the scale factor.
i.e.
[tex]New = Old * k[/tex]
So:
[tex]C' = (1,4) * 2 = (2,8)[/tex]
[tex]A' = (2,2) * 2 = (4,4)[/tex]
[tex]T' = (5,5) * 2 = (10,10)[/tex]

Kaitlyn is walking on a treadmill at a constant pace for 36 minutes. She has programmed
the treadmill for a 2-mile walk. The display counts backward to show the distance
remaining.
Enter and graph the equation that gives the distance f(x) left in miles as a function of the
number x of minutes she has been walking. Then, find and compete the interpretation of
the x- and y-intercepts.
The equation is f(x) =
Answer:
x int = (36,0)
y int = (0,2)
Step-by-step explanation:
Speed = distance / time
speed = 2/36 = 0.05555 Or 1/18 (as a fraction)
equation = f(x) = 2 - x/18
graph
The equation that gives the distance f(x) left in miles as a function of the number x of minutes she has been walking is [tex]f(x) = -\frac{x}{18} + 2[/tex]
The x-intercept of the graph is at (0, 2) which shows that the distance traveled at the beginning is 2 miles
The y-intercept of the graph is at (36, 0) which shows that no distance was covered when at when the time is 36 minutes
The general equation that represents the graph is expressed as:
[tex]f(x) = 2 - sx[/tex]
s is the speed of Kaitlyn
The formula for calculating the speed is expressed as;
[tex]speed = \frac{distance}{time}[/tex]
The function required will become;
[tex]f(x) = 2 - \frac{d}{t}x\\[/tex]
Given the following parameters
distance "d" = 2 miles
Time "t" = 36 minutes
Substitute the given parameters into the function as shown:
[tex]f(x) = 2 - \frac{2}{36}x\\f(x) = 2 - \frac{1}{18}x\\f(x) = -\frac{x}{18} + 2[/tex]
Hence the equation that gives the distance f(x) left in miles as a function of the number x of minutes she has been walking is [tex]f(x) = -\frac{x}{18} + 2[/tex]
Get the y-intercept of the function:
If x = 0
[tex]f(x) = -\frac{0}{18} + 2\\f(x) = 2[/tex]
The y-intercept of the function is (0, 2)
Get the x-intercept of the function
[tex]0 = -\frac{x}{18} + 2\\-2 = -\frac{x}{18} \\x = 36[/tex]
Hence the x-intercept of the graph is expressed as (36, 0)

What is the explicit formula for the arithmetic sequence 4/5, 29/30, 17/15, 13/10?
Answer:
The answer is D,
a(n) = 4/5 + 1/6(n- 1)
just took the test :)
Step-by-step explanation:
The explicit formula for the arithmetic sequence is D, a(n) = 4/5 + 1/6(n- 1)
What is arithmetic sequence?An arithmetic sequence is sequence of integers with its adjacent terms differing with one common difference.
The explicit formula is given by:
[tex]T_n = a + (n-1)d[/tex]
Where a is the first term (4/5) and d is the common difference (the difference is any 2 terms).
Therefore, to find d:
29/30 - 4/5
29/30 - 24/30
d = 5/30
d = 1/6
Now putting them into the formula:
a(n) = 4/5 + 1/6(n- 1)
The last answer choice is right.
