Your answer would be, Yes! It is an Isosceles Trapezoid, Because, Isosceles trapezoids have at least one set of opposite sides, that are parallel, mainly the base, and it's opposite. The non-base sides are equal in length to each other, and the base angles are equal to each other.








Hope that helps!!!!!!

Answer:

Yes, it is an isosceles trapezoid. In an isosceles trapezoid, its non-parallel sides make equal angles with the base and the two sides are equal.

Step-by-step explanation:

A trapezoid is a 3 dimensional figure formed from trapezium. It is a quadrilateral with one pair of parallel sides to be equal and a line of symmetry bisecting one pair of opposite sides.

A trapezoid with the two non-parallel sides the same length is called an isosceles trapezoid. Its non parallel sides make equal angles with the base.

Therefore, the rough sketch shows an isosceles trapezoid.

Eight expressions are given below. Determine whether each expression is equivalent to 5^10 or not equivalent to 5^10.
KengaRu [80]

Answer:

See Explanation

Step-by-step explanation:

The question is incomplete, as the 8 expressions are not given.

The general explanation is as follows

As complex as an expression may seem, you have to simplify each expression until it cannot be further simplified.

Then you categorize each result, depending on if it equals 5^{10} or not

Take for instance:

5^5 * 5^5

Using law of indices:

5^5 * 5^5 = 5^{5+5

5^5 * 5^5 = 5^{10 ---- equivalent

\frac{5^5 + 5^5}{2 * 5^{-5}}

Factorize the numerator

\frac{5^5 + 5^5}{2 * 5^{-5}} = \frac{5^5(1  + 1)}{2 * 5^{-5}}

\frac{5^5 + 5^5}{2 * 5^{-5}} = \frac{5^5 * 2}{2 * 5^{-5}}

Cancel out 2

\frac{5^5 + 5^5}{2 * 5^{-5}} = \frac{5^5}{5^{-5}}

Apply law of indices

\frac{5^5 + 5^5}{2 * 5^{-5}} = 5^{5--5}

\frac{5^5 + 5^5}{2 * 5^{-5}} = 5^{5+5}

\frac{5^5 + 5^5}{2 * 5^{-5}} = 5^{10 ---equivalent

125 * 78125

Express as exponent

125 * 78125  = 5^3 * 5^7

Apply law of indices

125 * 78125  = 5^{3+7

125 * 78125  = 5^{10 ---- equivalent

5^3 + 5^7

Solve exponents

5^3 + 5^7 = 125 + 78125

5^3 + 5^7 = 78250 ---- not equivalent

find the circumference and area of a circle with a diameter of 22 inches. leave your answers in the terms of pi
Roman55 [17]

Answer:

121π

Step-by-step explanation:

The formula for a circle is πr^2. But if given a diameter instead of radius, you simply divide by 2 because radius is half of a diameter.

Radius of this circle is 11 because you divide 22 by 2.

Then you follow the formula. 11^2=121.
