Answer:
Solving the equation [tex]x^2+6x-8=0[/tex] by completing the square method we get [tex]\mathbf{(x+3)^2=17}[/tex]
Option B is correct option.
Step-by-step explanation:
We need to solve the equation [tex]x^2+6x-8=0[/tex] by completing the square method.
For completing the square method: we need to follow: [tex]a^2+2ab+b^2=(a+b)^2[/tex]
We are given:
[tex]x^2+6x-8=0[/tex]
Solving by completing the square
[tex]x^2+2(x)(?)+(?)^2-8=0[/tex]
We need to find ? in our case ? is 3 because 2*3= 6 and our middle term is 6x i,e 2(x)(3)=6x.
So, adding and subtracting (3)^2
[tex]x^2+2(x)(3)+(3)^2-8-(3)^2=0\\(x+3)^2-8-9=0\\(x+3)^2-17=0\\(x+3)^2=17[/tex]
So, solving the equation [tex]x^2+6x-8=0[/tex] by completing the square method we get [tex]\mathbf{(x+3)^2=17}[/tex]
Option B is correct option.

whats 0.32 as a percent
Answer:
32%
Step-by-step explanation:
1.00 is 100%, so, 0.32 is 32%.
The decimal number 0.32 as a percentage is 32%.
We have,
To explain further, a percent is a way to represent a portion or a fraction of 100. When we multiply a decimal number by 100, we essentially scale it up to the corresponding percentage value.
In the case of 0.32, multiplying it by 100 yields 32, which represents 32% of the whole. So, 0.32 is equivalent to 32%.
To express 0.32 as a percent, we multiply the decimal value by 100.
So,
In this case,
To convert 0.32 to a percent, we perform the calculation:
0.32 x 100 = 32
Therefore,
0.32 as a percentage is 32%.

Write a compound inequality that represents the following scenario: The cost for any regular priced treat, t, in the store ranges between 1.25
and 5.99.
Answer:
The inequality will be: 1.25<t<5.99
Step-by-step explanation:
Inequalities are used to represent a range or less than or greater than quantities.
Compound inequalities are used to define ranges for a variable.
In the given statement,
t, in the store ranges between 1.25 and 5.99.
This means that t will be greater than 1.25 and less than 5.99
So,
The inequality will be: 1.25<t<5.99

The angle of depression is 30 degrees from the bottom of the boat to a
deep sea diver a the depth of 120 ft. Find the distance x the diver must
swim up to the boat to the nearest foot. (Round, no decimal answers
please). *
x ft
120 ft
Answer:
x = 240 feet
Step-by-step explanation:
It is given that,
The angle of depression is 30 degrees from the bottom of the boat to a deep sea diver at the depth of 120 ft.
We need to find the distance x the diver must swim up to the boat. It can be calculate by applying trigonometry as follows :
[tex]\sin30=\dfrac{120}{x}\\\\x=\dfrac{120}{\sin30}\\\\x=240\ \text{feet}[/tex]
So, the distance the diver must swim up to the boat is 240 feet.

The roots of the quadratic equation will be -
{x} = (1 ± i√29)/5
What are algebraic expressions?In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.Given is the quadratic equation as -
5x² - 2x + 6 = 0
We can write the roots as -
{x} = {- b ± √(b² - 4ac)/2a}
{x} = (2 ± √-116)/10
{x} = (2 ± i 2√29)/10
{x} = 2(1 ± i√29)/10
{x} = (1 ± i√29)/5
Therefore, the roots of the quadratic equation will be -
{x} = (1 ± i√29)/5
