They both have four sides, and they both have at least one pair of sides that are parallel.

Trapezoid and paralellogram are both quadrilaterals

the heiarchy is
quadrilaterals are 4 sided figures
quadrilaterals is split up into
      A. no pairs of paralell sides
   - kite
   B. 1 pair of paralell sides
   - trapezoid/trapezium
C. 2 pairs of parell sides (paralellograms)
   -rectangles
   -rhombus
   -square

so you can see that they are both quadrilaterals (quad=4, lateral=sides, quadrilateral=4 sided figure)

What is the area of the figure? 40 ft2 84 ft2 96 ft2 can't be determined

mina [271]

Answer:

$A=80\ ft^2$

Step-by-step explanation:

we know that

The area of the figure is equal to the area of an isosceles triangle (has two equal sides) plus the area of a rectangle

step 1

Find the area of the triangle

The area of the triangle is equal to

$A=\frac{1}{2}bh$

we have

$b=16\ ft$

To find out the height of the triangle Apply the Pythagorean Theorem

$10^2=(16/2)^2+h^2$

solve for h

$100=64+h^2$

$h^2=100-64$

$h^2=36$

$h=6\ ft$

Find the area of triangle

$A=\frac{1}{2}(16)(6)$

$A=48\ ft^2$

step 2

Find the area of rectangle

The area of rectangle is equal to

$A=LW$

we have

$L=16\ ft\\W=2\ ft$

substitute

$A=(16)(2)=32\ ft^2$

step 3

Find the area of the figure

Adds the areas

$A=48+32=80\ ft^2$

Can anybody tell me the answers to number 1, 2 & 3 ???!!!!

Problem 1

Domain = {-1, -3, 2, 1}

Range = {5, 0, 2}

The domain is the set of possible inputs and the range is the set of possible outputs. This is a function because each input goes to exactly one output.

========================================

Problem 2

This is a function as well. We do not have any input going to multiple outputs.

Domain = {-2, -3, 5}

Range = {6, 7, 8}

========================================

Problem 3

This is not a function. The input -4 goes to more than one output (outputs 3 and -1 at the same time)

Domain = {-4, -2, 0}

Range = {3, -1, -2, 4}
