Answer:
[tex]x=\frac{\sqrt{2}}{2}[/tex]
Step-by-step explanation:
The given triangle is an isosceles right triangle, meaning that the 45-45-90 triangle side rule applies. The 45-45-90 triangle side rule states that the two legs (sides that are adjacent to the right angle) are congruent, and the hypotenuse (the side opposite the rights angle) is equal to the leg times the square root of two. Using this property, one knows that the leg is equal to the hypotenuse divided by the square root of two. In this problem, the hypotenuse is equal to (1), and the leg is equal to (x). Therefore, one can say,
[tex]x = \frac{1}{\sqrt{2}}[/tex]
Rationalize the denominator,
[tex]\frac{1}{\sqrt{2}}*\frac{\sqrt{2}}{\sqrt{2}}\\\\\frac{\sqrt{2}}{2}[/tex]
Answer:
Step-by-step explanation:
a² + b² = c² look familiar? it is the Pythagorean theorem
both side are the same length since both angles are the same some sort of Isosceles triangle rule I think so side 1 = x side 2 = x and hypotenuse = 1
x² + x² = 1²
2x² = 1
x² = 1/2
x = √(1/2) the denominator is NOT rational in this FORM
x = √1 / √2 multiple the numerator and the denominator by √2
x = 1 (√2) / (√2)(√2)
x = √2 / √2²
x = √2 / 2 finding a rational denominators means nothing
just do more work and more typing for me,
a silly MATH rule
x = √2/2 = 0.7071 x = √(1/2) = √(0.5) = 0.7071 the SAME Number

Cooper is going to invest $2,100 and leave it in an account for 14 years. Assuming the interest is compounded monthly, what interest rate, to the nearest tenth of a percent, would be required in order for Cooper to end up with $5,300?

6.6
Step-by-step explanation:

The interest rate annually will be 6.6% for the given compound interest will be 6.6%.
What is compound interest?
Compound interest is applicable when there will be a change in principal amount after the given time period.
For example, if you give anyone $500 at the rate of 10% annually then $500 is your principle amount.
As per the given,
Principle amount P = $2100
Time period T = 14 years
The annual rate of interest is R
Total investment = $5300
Number of times interest applied per time period n = 12
By compound interest formula,
5300 = 2100[1 + R/(100)]^(12 x 14)
(1 + R/1200)¹⁶⁸ = 5.524
1 + R/1200 = 5.51 x 10⁻³
R = 6.6% annually
Hence "The interest rate annually will be 6.6% for the given compound interest will be 6.6%".

Answer:
I think you are intended to answer parallel lines
Step-by-step explanation:
There are two answers to this.
1) The lines could be parallel if their y intercepts are different.
2) The lines are different forms of the same line.
For example
parallel:
y = 3x + 5y = 3x - 2Different forms of the same line.
y = 4x + 22y = 8x +4The second condition is termed consistent. The second condition is of 2 lines with the same slope and the same y intercept.

Answers
Given:
The system of equation is
[tex]y=-8x-3[/tex]
[tex]x+y=7[/tex]
To find:
Whether (3,4) is a solution of the given system or not.
Solution:
We have,
[tex]y=-8x-3[/tex] ...(i)
[tex]x+y=7[/tex] ...(ii)
Putting the value of y in (ii) from (i), we get
[tex]x+(-8x-3)=7[/tex]
[tex]x-8x-3=7[/tex]
[tex]-7x=7+3[/tex]
[tex]-7x=10[/tex]
Divide both sides by -7.
[tex]x=\dfrac{10}{-7}[/tex]
[tex]x=-\dfrac{10}{7}[/tex]
Putting [tex]x=-\dfrac{10}{7}[/tex] in (i), we get
[tex]y=-8\times (\dfrac{-10}{7})-3[/tex]
[tex]y=\dfrac{80}{7}-3[/tex]
[tex]y=\dfrac{80-21}{7}[/tex]
[tex]y=\dfrac{59}{7}[/tex]
So, the only solution of the given system is [tex]\left(-\dfrac{10}{7},\dfrac{59}{7}\right)[/tex].
Hence, (3,4) cannot be a solution of given system, Hence the correct option is B.

Which expression shows the prime factorization of 180?
22 X 32 X 5
2 X 32 X 52
2 X 3 X 5
22 X 3 X 52
Answers
Answer:
1- 3520
2- 3328
3- 30
4- 3432
Step-by-step explanation:
========================================================
Explanation:
To find the prime factorization, we'll start by dividing 180 by the smallest prime number
Divide 180 by 2 to get 180/2 = 90
Divide that by 2 to get 90/2 = 45
Then note how 45/2 = 22.5 isn't a whole number, so that means we move onto the next prime number 3
45/3 = 15
15/3 = 5
The denominators we used, in order, were: 2, 2, 3, 3
This means that 2*2*3*3 is part of the factorization. We can condense that to 2^2*3^2
The last term 5 is the final missing piece of the factor puzzle
Meaning, 2^2*3^2*5 = 180
I recommend you use a calculator to confirm this.

Answers
Answer: 2205
Step-by-step explanation:
Ratio of the number of students accepted to the number of students applying for admission = 2:7
Number of students accepted = 630 students
Number of students that applied will then be represented by x. This will be:
2/7 = 630/x
2 × x = 630 × 7
2x = 4410
x = 4410/2
x = 2205
The number of students that applied to the university was 2205
