Answer:

Not an isosceles trapezoid

Step-by-step explanation:

Plot the given points.

We can see and visually confirm this is not isosceles.

(1,1) to (3, 3) distance is:

$AD = \sqrt{(1-3)^2+(1-3)^2 } = \sqrt{8} = 2\sqrt{2}$

(5,3) to (8, 1) distance is:

$BC = \sqrt{(5-8)^2+(3-1)^2 } = \sqrt{13}$

We see AD ≠ BC

The sides are not of the same length.

Polynomial Roots Calculator :

2.1 Find roots (zeroes) of : F(a) = 7a3-7a+1

Polynomial Roots Calculator is a set of methods aimed at finding values of a for which F(a)=0

Rational Roots Test is one of the above mentioned tools. It would only find Rational Roots that is numbers a which can be expressed as the quotient of two integers

The Rational Root Theorem states that if a polynomial zeroes for a rational number P/Q then P is a factor of the Trailing Constant and Q is a factor of the Leading Coefficient

In this case, the Leading Coefficient is 7 and the Trailing Constant is 1.

The factor(s) are:

of the Leading Coefficient : 1,7

of the Trailing Constant : 1

Let us test ....

P Q P/Q F(P/Q) Divisor

-1 1 -1.00 1.00

-1 7 -0.14 1.98

1 1 1.00 1.00

1 7 0.14 0.02

Polynomial Roots Calculator found no rational roots

Final result :

7a3 - 7a + 1

Kermit's favorite iced tea is made with 151515 tea bags in every 222 liters of water. Peggy made a 121212-liter batch of iced te

muminat

Answer:

The answer is (Choice C) It is just right.

Step-by-step explanation:

The question is incomplete, so the complete question is below:

Kermit's favorite iced tea is made with 15 tea bags in every 2 liters of water. Peggy made a 12-liter batch of iced tea with 90 tea bags. What will Kermit think of Peggy's iced tea? Choose 1 answer: (Choice A) It is too strong. (Choice B) It is too weak. (Choice C) It is just right.

Now, to find which of the choice is correct.

So, we find first the unit rate of Peggy's iced tea bags per liter:

If, Peggy made a 12-liter batch of iced tea with 90 tea bags.

Then, Peggy would made a 1-liter batch of iced tea with = $\frac{90}{12} =7.5\ tea\ bags.$

Now, to get the unit rate of Kermit's iced tea bags per liter:

If, Kermit made a 2 liter of iced tea with 15 tea bags.

Then, Kermit would made a 2 liter of iced tea with = $\frac{15}{2} =7.5\ tea\ bags.$

Thus, the quantity of tea bags per liter is same of both Kermit and Peggy.

Hence, Kermit will think of Peggy's iced tea that it is just right.

Therefore, the answer is (Choice C) It is just right.

Answer:

Step-by-step explanation:

Use the pythagorean theorem

a² + b² = c²

3² + 4² = c²

9 + 16 = c²

25 = c²

5 = c
