Answer:

The first one is a function because, for each x-value (domain value) there is exactly one y-value (range value).

The second one is not a function because, not each x-value (domain value) has exactly one y-value (range value). The domain value of 5 has two range values of 13 and 9.

If a parallelogram has diagonals that are perpendicular bisectors of each other, what is the most descriptive name for it?

Feliz [49]

Both a rhombus and a rectangle have diagonals that are perpendicular bisectors, but the ones formed in a square are all congruent, so that is probably the most descriptive one.

Answer:

Option A. one rectangle and two triangles

Option E. one triangle and one trapezoid

Step-by-step explanation:

step 1

we know that

The area of the polygon can be decomposed into one rectangle and two triangles

see the attached figure N 1

therefore

Te area of the composite figure is equal to the area of one rectangle plus the area of two triangles

$A=(8)(4)+2[\frac{1}{2}((8)(4)]=32+32=64\ yd^2$

step 2

we know that

The area of the polygon can be decomposed into one triangle and one trapezoid

see the attached figure N 2

therefore

Te area of the composite figure is equal to the area of one triangle plus the area of one trapezoid

$A=\frac{1}{2}(8)(4)+\frac{1}{2}((4+8)(8)=16+48=64\ yd^2$

What is the greatest common factor of 20x6y+40x4y2−10x5y5 ?

mestny [16]

The greatest common factor: 20x^6y 40x^4y^2 10x^5y^5 is 10x^4y.
20x^6y = 10x^4y*2x^2
40x^4y^2 = 10x^4y*4y
10x^5y^5 = 10x^4y*y^4

A recipe requires 1/4 lb of onions to make 3 servings of soup. Mark has 1 1/2 lb of onions. How many servings can Mark make?

Oxana [17]

⓵ You have to do a cross product in order to find your answer :

1/4 lb → 3 servings
1 ½ lb → × servings

(3 x 1 ½) ÷ 1/4 = (3 x 1,5) ÷ 0,25

⓶ Now you need to solve the equation :

(3 x 1,5) ÷ 0,25

↓

(4,5) ÷ 0,25

↓

4,5 ÷ 0,25 = 18

Which means that your final answer is that Mark can make 18 servings with 1 ½ lb of onions!

I hope this helped! ☻
