Answer:
x = - 8 and (- 8, 0 )
Step-by-step explanation:
Given a quadratic in standard form
y = ax² + bx + c ( a ≠ 0 )
Then the equation of the axis of symmetry which is also the x- coordinate of the vertex is
x = - [tex]\frac{b}{2a}[/tex]
y = x² + 16x + 64 ← is in standard form, with
a = 1 and b = 16, then
x = - [tex]\frac{16}{2}[/tex] = - 8
Equation of axis of symmetry is x = - 8
Substitute x = - 8 into the quadratic and evaluate for y
y = (- 8)² + 16(- 8) + 64 = 64 - 128 + 64 = 0
vertex = (- 8, 0 )

The 7th term of the geometric sequence 13, 26, 52, 104, ... is
Answers
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

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?
Answers
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
Answers
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

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

-12
12
Answers
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
