Answer:
Geometric
Step-by-step explanation:
The given sequence is; 39, 156, 468, and 936 Geometric sequence.
What is a geometric sequence and how to find its nth term?Three parameters differentiate between which geometric sequence we're talking about. The first parameter is the initial value of the sequence. The second parameter is the quantity by which we multiply the previous term to get the next term. And the third parameter is the length of the sequence. It can be finite or infinite.
Consider that the initial term of a geometric sequence is a and the term by which we multiply the previous term to get the next term is r.
Thus, the nth term of such sequence would be; [tex]T_n = ar^{n-1}[/tex]
We have been given that the sequence is; 39, 156, 468, 936
Hence, the given sequence is; 39, 156, 468, and 936 Geometric sequence.

x-7=15
Answer:
x = 22
Step-by-step explanation:
x = 7 + 15
x = 22
Answer:
x = 22
Step-by-step explanation:
1x - 7 = 15
1x = 15 + 7
1x = 22 (divide both sides by the first number/1 to get x)
1x/1 = 22/1
x = 22

Can somebody explain why 8/17 is correct. Will make brainliest.
Answer:
8/17 is correct because cosine = adjacent/hypotenuse, and since angle A is theta, or the reference angle, the adjacent of A would be 8, and the hypotenuse is always across the right angle.
15/17 would be sine instead of cosine

List the sides of the triangle in order from shortest to longest
Answer:
To put the sides in order of longest to shortest, first find the largest angle -- the longest side is opposite this angle. Then, find the second largest angle and the side opposite from it to find the next largest angle, and finally, the shortest side will be opposite the smallest angle.

Select all the expressions that are equivalent to 16x - 12 - 24x + 4
1) 4 + 16x - 12(1 + 2x)
2) 40x - 16
3) 16x - 24x - 4 + 12
4) -8x - 8
Answer:
(1) and (4)
Step-by-step explanation:
4 + 16x - 12(1 + 2x) = 4 + 16x - 12 - 24x
4 + 16x - 12 - 24x = 16x - 12 - 24x + 4
- 24x + 16x = -8x
- 12 + 4 = -8
Which creates -8x - 8
Simplify 12 + (-4) - 2/5J -4/5j +5
Answer:
13 - 6j/5
Step-by-step explanation:
After simplification of the given equation, the value obtained is equal to (13 - 6j)/5.
What is Simplification?A phrase must be simplified and made shorter using a variety of methods. The steps required to decrease something are carried out according to a specified order known as BODMAS.
Make a fraction simpler by reducing it to the base form. If both the numerator and denominator of a fraction only include the integer, the fraction is considered to be in its basic form.
As per the data given in the question,
12 + (-4) -2/5j - 4/5j + 5
12 - 4 + 5 - 2/5j - 4/5j
13 - (2 - 4)j/5
= (13 - 6j)/5

while shooting Baskets at a basketball hoop you make 36 out of 80 shots your friend makes 43.75 percent of the shots who made a higher percent
Answer:
The 'your friend' made a higher percentage of shots .
Step-by-step explanation:
80 - 43.75 = 36.25
80 is the total amount
36 (36.25) is YOUR amount
43.75 is 'your friends' amount
and with the equation I shows at the top 'your friend' has the higher number of percent from the shots compared to you

25 points. Which problem will graph as shown?
A) 3x - 5 ≥ -14
B) 3x - 5 ≤ -14
C) 3x - 5 > -14
D) 3x - 5 < -14
Answer:
D
Step-by-step explanation:
We can work backwards.
First, notice that we have an open circle. So, we do not have "or equal to." So, we can ignore A and B.
Our final answer is all values less than -3. So:
[tex]x<-3[/tex]
We can multiply both sides by 3:
[tex]3x<-9[/tex]
And then subtract 5 from both sides:
[tex]3x-5<-14[/tex]
So, the answer that matches this will be D.
Instead of working backwards, you can also just solve each inequality. Since we have an open circle, we only need to solve C and D. If we solve C, we get x > -3, and if we solve D, we get x < -3 (as desired). So, D matches the graph shown.

at point (0,2) can be reflected across the x-axis PLEASE HELP 50 POINTS true pr false
Answer:
Please check the explanation.
Step-by-step explanation:
When a point P(x, y) is reflected across the x-axis, all we need to do is to reverse the sign value of the y-coordinate of any given point while the x-value remains the same.
Thus,
The rule to reflect over the x-axis is:
P(x, y) → P'(x, -y)
In our case, the point, let's say A(0, 2), is reflected across the x-axis. Thus, the coordinates of A' will be:
P(x, y) → P'(x, -y)
A(0, 2) → A'(0, -2)
So, YES! point A(0,2) can be reflected across the x-axis and the coordinates of A' will be: A'(0, -2).
