Does a triangle with side lengths 5, 5 and 5root2 form a right triangle?
Answers
25 + 25 = (5*1.414...)^2 =
50 =(7.0710678119) ^2
and 7.0710678119^2 = 50 so it is a right triangle.
To be specific, it is an isosceles right triangle.

Step-by-step explanation:
Final answer:
To find the sum of the polynomials, add the like terms together. The sum of the given polynomials is 10x^2 + 3x - 2.
Explanation:
To find the sum of the polynomials, you need to add the like terms together. Start by adding the coefficients of the x-squared terms, which are 8 and 2. This gives you 10x^2. Then, add the coefficients of the x-terms, which are -7 and 10. This gives you 3x. Finally, add the constant terms, which are 3 and -5. This gives you -2. So, the sum of the polynomials is 10x^2 + 3x - 2.

many days do they earn the same amount?
Answers
Answer:
They earn the same amount after 8 days.
Step-by-step explanation:
When both started working(the day Jack started, John had been working for 2 days earning $24 a day, so he already had 2*24 = $48). We started modeling from this day.
John:
He already had $48.
He would earn $24 per day.
So after n days, his amount would be:
Jack:
He has nothing.
He would earn $30.
So after n days, his amount would be:
After how many days do they earn the same amount?
After n days.
n is found when:
They earn the same amount after 8 days.

We know that the Pythagorean Theorem is the following:
where c is the hypotenuse (the side opposite the right angle), and a and b are the legs of the triangle.
To solve, we just have to input what we know. The two legs of the triangle are 60 and 100, so we just have to plug these values in and solve.
So we know that the distance from one corner of the playing field to the opposite corner is the square root of 13,600 yards.
When we plug this into a calculator, we get
which, when rounded up to the nearest whole number, is 117.
The approximate distance from one corner of the soccer field to the opposite corner is 117 yards.

y = -2x² + 8x - 12
+ 12 + 12
y + 12 = -2x² + 8x
y + 12 - 8 = -2x² + 8x - 8
y - 4 = -2(x²) - 2(-4x) - 2(4)
y - 4 = -2(x² - 4x + 4)
y - 4 = -2(x² - 2x - 2x + 4)
y - 4 = -2[x(x) - x(2) - 2(x) - 2(-2)]
y - 4 = -2[x(x - 2) - 2(x - 2)]
y - 4 = -2(x - 2)(x - 2)
y - 4 = -2(x - 2)²
+ 4 + 4
y = -2(x - 2)² + 4
