Question 20Identify the area of the polygon with vertices B (3, 2), C (7,-2), D (2,-4), and E (1, -2).
A = 19 units2
A = 17 units2
A = 30 units
A = 18 units2

Answers

Answer 1

Answer:

9514 1404 393

Answer:

(d) A = 18 units²

Step-by-step explanation:

Line CE can be considered to be the base of two triangles. It is 6 units long. The upper triangle is 4 units high, and the lower triangle is 2 units high. The formula for the area of a triangle is ...

A = 1/2bh

Then the sum of the areas of the two triangles is ...

A = 1/2(6)(4) +1/2(6)(2) = 12 +6 = 18

The area of the polygon is 18 square units.

Answer 2

Answer:

Answer: A=18units2

Step-by-step explanation:

I said 17 before and got it wrong lol.

Next time I said 18 cuz it seemed like the closest when I estimated what it looked like the units it covered, so it's right:)

hope it helps!

Write a formula for the general term or nth term for the sequence. Then find the indicated term. three fourths comma three sixteenths comma StartFraction 3 Over 64 EndFraction comma StartFraction 3 Over 256 EndFraction ...; a 8

Answers

Sequence: 3/4, 3/16, 3/64, 3/256
a8=?
a1=3/4
a2=3/16
a3=3/64
a4=3/256

a2/a1=(3/16)/(3/4)=(3/16)*(4/3)=4/16=1/4
a3/a2=(3/64)/(3/16)=(3/64)*(16/3)=16/64=1/4
a4/a3=(3/256)/(3/64)=(3/256)*(64/3)=64/256=1/4
a2/a1=a3/a2=a4/a3=r=1/4

an=a1*r^(n-1)
an=(3/4)*(1/4)^(n-1)
an=(3/4)*(1)^(n-1)/(4)^(n-1)
an=(3/4)*(1/4^(n-1))
an=(3*1)/[4*4^(n-1)]
an=3/4^(1+n-1)
an=3/4^n

n=8→a8=3/4^8
a8=3/65,536

Answers:
The general term or nth term for the sequence is: an=3/4^n
a8=3/65,536

Anthony makes candies. First, he mixes 1 cup of cream with 2 cups of chocolate. In all, he used 9 cups of these 2 ingredients. How many cups of chocolate does he use in this candy recipe?

Answers

Answer:

6 cups

Step-by-step explanation:

Anthony's recipe uses 2 cups of chocolate for each 3 cups of the two ingredients. So, the chocolate is 2/3 of the total number of cups of the two ingredients.

2/3 × 9 cups = 6 cups

Anthony uses 6 cups of chocolate to make the candies.
