Answer:
4.5
Step-by-step explanation:
The scale factor is 2
This means that the sides are proportional by a factor of 2.
In other words, you multiply 2 with the side lengths of first trapezoid to get the side length of second trapezoid.
You can see the pattern:
12 goes with 24
4.5 goes with 9
7 goes with 14
<u>X goes with 9</u>
<u></u>
The "X" is the missing side.
As you can see, we multiply each number on the left-hand side by 2 to get the number on the right-hand side (larger trapezoid).
So, that means:
X multiplied by "2" will gives us 9, we can write:
Complete the equation and find x:
The missing side length in the original trapezoid is "4.5"
Answer:
- circumference: 12.56 yd
- area: 12.56 yd²
Step-by-step explanation:
The formula for circumference is ...
C = πd
C = (3.14)(4 yd) = 12.56 yd . . . . . . . . fill in the numbers; do the arithmetic
The circumference is 12.56 yd.
__
Since the diameter is 4 yd, the radius is half that, or 2 yd. The formula for the area is ...
A = πr²
Fill in the numbers and do the arithmetic.
A = (3.14)(2 yd)² = 12.56 yd²
The area is 12.56 yd².

<em>Comment on units</em>
In problems such as these, I find it is often useful to keep the units with the numbers. The units can be treated like any variable: multiplied, divided, measures combined by addition or subtraction of "like units".
Just as (2a)² = 2²·a² = 4a², so does (2 yd)² = 2²·yd² = 4 yd². You can be sure that if the units of the problem don't make sense, there is an error somewhere.

Answer:
<em>B. 25,636 feet</em>
Step-by-step explanation:
sin(55) = h/x
h = 21,000
sin(55) = 21,000/x
x = 21,000/sin(55)
x = 25636.27 ≈ 25,636 feet

Answer:
a.Z(-2,1)
b.Z(1,1)
c.Z(-3,2)
Step-by-step explanation:
z(-2,3)
Imagine this point on a graph.
Translate it down two units :
the x stays -2, by going down the y decreases 2 so 3-2=1
Z(-2,1)
Translate Right three units : I'm assuming that we use the answer from the first translation
Z(-2,1)
The y doesn't change this time the x increases 3 since we're moving to the right.
Z(1,1)
Translate up 1 and left 4:
Z(1,1)
by moving up one we have Z(1,2) then by moving 4 to the left we get Z(-3,2)
Hope this helps :)
