Sara uses a scale of 1 cm : 12 m to draw a floor plan of a

1 answer:

8 0

The correct answer is B. So for A, 8m is smaller than 12 m. For B, 20 m is Bigger. For C, Find how many meters is 1 centimeter, the answer is 1 cm : 12m, the meter is not bigger than 12, but the same, so C is wrong. For D, divide both sides by 3 to find 1 CM, the answer is 1 cm : 5 m, it is wrong.

Answer:

vertex is (4,-4) and another point is (6,0) or you could use (2,0) or many other options :)

Step-by-step explanation:

The cool thing about this question your quadratic is in factored form so your x-intercepts are easy to figure out, they are 2 and 6.

So you can plot (6,0) and (2,0).

The vertex will lie half between x=2 and x=6... so it lays at (6+2)/2=4

We just have to find the y-coordinate for when x=4.

Plug in 4 gives you (4-2)(4-6)=(2)(-2)=-4.

So the vertex is at (4,-4).

Find the lateral area for the given cylinder. use 3.14 for pi and round to the nearest whole number

OverLord2011 [107]

Formula for lateral area of cylinder:
A $A_{L}=2 \pi rh$
Here r=6 units and h=26 units
Put values in formula.
$A _{L} =2(3.14)(6)(26) \\ A_{L}=980\ square \ units$ \\
(rounded to nearest whole number)

Answer: Lateral area of cylinder= 980 square units
