The 7th term of the geometric sequence 13, 26, 52, 104, ... is
832
let first term = n
second term = 2 x n
third term = 4 x n
forth term = 8 x n
therefore we can concluded that the multiple are the sum of itself ( 2+2= 4, 4+4=8, 8+8=16, 16+ 16=32,) some the seventh term will be 32 + 32 which is 64 .
therefore
seventh term = 64 x n
= 64 x 13 = 832

What is the distance from -7 to 5 on a number line?

-12
12
Answer:
12 units
Step-by-step explanation:
Find the absolute value of the difference , that is
d = | - 7 - 5 | = | - 12 | = 12 or
d = | 5 - (- 7) | = | 5 + 7 | = | 12 | = 12
The distance from -7 to 5 on a number line is 12 units. This distance between two integers is calculated by using a number line and the absolute value of the difference between those two integers.
What is a Number line?A number line is a graph for the real numbers.It is used to represent the integers on it at a regular interval. It is also used for finding arithmetic operations like the addition and subtraction of integers.The positive integers lie on the right side of the number line and the negative integers lie on the left side of the line The zero lies at the center of the line which separates the positive and negative integers.How to calculate the distance between two integers on a number line?For calculating the distance between two integers, count every integer in between themA faster way of finding the distance between the two integers is by taking the absolute value of their differenceIf A and B are two integers, then the distance between them is given by |B - A|Calculating the distance from -7 to 5 on the number line:
⇒ | 5 - (-7) |
⇒ | 12 |
= 12 units
Therefore, there are 12 units in between the given two integers -7 and 5 on a number line which is shown below

Tom is an artist and plans to paint and sell some miniature paintings. The paint and canvas for each painting costs $10 and then he bought some brushes for $50. If he plans on selling each painting for $20, how many paintings must Tom sell to break even?
Answer:
3
Step-by-step explanation:
50+10=60
20 x 3= 60
Tom needs to sell at least 5 paintings to break even.
What are the cost price and selling price?1. Cost price = Selling price − profit ( when selling price and profit are given )
2. Cost price = Selling price + loss ( when selling price and loss are given )
Given here each canvas and painting cost $10 and he bought brushes for $50. Now for each painting his profit is = $20-$10 = $10 but he has still miscellaneous expenses for the brushes to account for hence to break even he has to make a profit totaling $50 thus he must sell 5 paintings to break even.
Hence, he has to sell 5 paintings

A right cone has a slant height of 17 feet, and the diameter of the base is 16
feet. What is the height, h, of the cone?
h
17 ft
16 ft
Answer:
15 ft
Step-by-step explanation:
A right triangle is formed by h, the radius and the slant height
Given diameter = 16, then radius = 16 ÷ 2 = 8
Using Pythagoras' identity in the right triangle with legs h and 8 and hypotenuse the slant height, then
h² + 8² = 17²
h² + 64 = 289 ( subtract 64 from both sides )
h² = 225 ( take the square root of both sides )
h = [tex]\sqrt{225}[/tex] = 15

The following triangle is equilaterial triangle. Solve for the unknown variable.
Answer:
d
Step-by-step explanation:
Since the triangle is equilateral then the 3 sides are congruent, then
2x = 6 ( divide both sides by 2 )
x = 3
and
3y = 6 ( divide both sides by 3 )
y = 2
Thus x = 3 and y = 2 → d

Using the quadratic formula to solve 7x2 -x = 7, what are the values of x?
Answer:
x=-7
Step-by-step explanation:
7x2-x=7
7x2=14.
14-x=7
When you finished the last step, you will subtract 14 to both sides.
14-x=7
14-14-x=7-14
this will cancel out the 14 on the left.
And will leave you with:
-x=7-14
7-14 is -7.
and this will get you to
-x=-7
To finish this off, you have to turn the negative x/variable, into a positive x/variable.
So, you will divide both sides of the equation by the same term.
-x = -7
into
[tex]\frac{-x}{1} =\frac{-7}{1}[/tex]
and it will be -7.
I hope this helps :)

Y is less than or equal to -2
Y is less than or equal to 0
Y is less than or equal to -1
all real numbers
Answer: y is less than or equal to -1
How?
The graphs highest value it will ever reach, range wise, is -1. Therefore it isnt 0, or all real numbers.
The reason why it is -1 and not -2 is because the curve hits -1. Sure, -2 is included in the range, but y is less than or equal to -1 INCLUDES -2
