The Pythagorean theorem states that the sum of the squares of the legs of a right triangle is equal to the square of the
hypotenuse by the formula a? + b2 = -2
If a is a rational number and b is a rational number, why could c be an irrational number?
Answer:
For the value of hypotenuse can be irrational, sum of squares of other two legs might be imperfect square number.
Step-by-step explanation:
We all know, the Pythagorean theorem can be stated as follows:
The sum of squares of two legs of a right angled triangle is equal to the square of the hypotenuse.
i.e.
[tex]a^2+b^2=c^2[/tex]
Where, [tex]c[/tex] is the hypotenuse and [tex]a, b[/tex] are the two other legs of the right angled triangle.
Given that:
[tex]a[/tex] and [tex]b[/tex] are rational numbers.
To find:
Situation for which [tex]c[/tex] is irrational.
Square of a rational number is always rational.
So, [tex]a^{2} , b^{2}[/tex] both will be rational.
And sum of squares of two rational numbers will also be rational.
Therefore, [tex]a^2+b^2[/tex] will also be rational.
and
[tex]c = \sqrt{a^2+b^2}[/tex]
For the value of [tex]c[/tex] can be irrational, sum of squares of other two legs might be imperfect square number.

is y=x squared a linear or nonlinear function
Answer:
Linear. y = x also equals y = 1x, and you can put a line on a graph using this equation, hence the name linear.

What is the solution to the equation fraction 3 over 5 n minus fraction 4 over 5 equals fraction 1 over 5 n?
n = fraction 5 over 2
n = −1
n = fraction 5 over 3
n = 2
9514 1404 393
Answer:
n = 5/3
Step-by-step explanation:
Eliminate fractions, add 4, divide by the coefficient of n.
[tex]\dfrac{3}{5} n-\dfrac{4}{5}=\dfrac{1}{5}\\\\3n-4=1 \qquad\text{multiply by 5}\\\\3n=5 \qquad\text{add4}\\\\\boxed{n=\dfrac{5}{3}} \qquad\text{divide by 3}[/tex]
During a flood, James used two pumps to get the water out of his
basement. The big pump moves 3 gallons of water per minute. The
small pump moves 4 gallons in 5 minutes. How many more gallons
does the big pump move than the small pump after 10 minutes?
Answer:
The big pump moves 22 more gallons in 10mins
Step-by-step explanation:
The total the big pump moves is 30 gallons in 10mins because 3x10 = 30
The small pump moves 8 gallons in 10mins becuase 4x2= 8
Its asking for how many more so 30 - 8 = 22 More gallons
Regina spent $45.50 over 612 months on music downloads.
If she spent the same amount of money each month, how much money did Regina spend per month on music downloads?
Answer:
.07 cents
Step-by-step explanation:
In order to solve this question all you need to do is divide the money spent by the amount of months. 45.50/612=0.0743464052 but since you cant spend .0043464052 of a cent we have to change the answer to .07. To check our answer is right all we need to do is multiply 0.0743464052 by 612=45.499999 so we know the answer is correct.

-4n(5n+6)-5(3+3n)
Answer: -20n^2 - 39n - 15
Step-by-step explanation:
first, we remove the parenthesis (multiply everything out).
-20n^2 - 24n - 15 - 15n
then, we simply collect like terms.
-20n^2 - 39n - 15
Answer:
-20n^2-39n-15
Step-by-step explanation:
Given: -4n(5n+6)-5(3+3n)
Use the distributive property: -20n^2-24n-15-15n
Combine like terms: -20n^2-39n-15
Your simplified expression is -20n^2-39n-15
Find the equation of the line that is perpendicular to the given line and passes through the given point. Enter your answer in slope-intercept form (y=mx+b) with the values of m and b given as decimals, rounded to the nearest hundredth if necessary.
y=2x;(9,-4)
The equation is y=
Answer:
y = -1/2x + 1/2
Step-by-step explanation:
perpendicular lines have slopes that are opposite signs and reciprocal
therefore, use m=-1/2 and point (9, -4) to complete the equation by finding 'b' (the y-intercept)
-4 = -1/2(9) + b
-4 = -9/2 + b
-4 + 9/2 = b
-4 + 4 [tex]\frac{1}{2}[/tex] = b
b = [tex]\frac{1}{2}[/tex]

16, 3x + 2y = 8 5x+ 2y = 12 What is the solution of the system of equations shown above? A(-2,7) B. (2,1)
C.4/3,2
D
2,4
Answer:
The solution of the system of the equations is (2, 1) ⇒ B
Step-by-step explanation:
Let us solve the system of equations
∵ 3x + 2y = 8 ⇒ (1)
∵ 5x + 2y = 12 ⇒ (2)
→ Subtract equation (1) from equation (2)
∴ (5x - 3x) + (2y - 2y) = (12 - 8)
∴ 2x + 0 = 4
∴ 2x = 4
→ Divide both sides by 2
∴ x = 2
→ Substitute the value of x in equation (1) or (2) to find y
∵ 3(2) + 2y = 8
∴ 6 + 2y = 8
→ Subtract 6 from both sides
∵ 6 - 6 + 2y = 8 - 6
∴ 2y = 2
→ Divide both sides by 2 to find y
∴ y = 1
∴ The solution of the system of the equations is (2, 1)
