Answer:
2. A = 12ft * 8ft
Step-by-step explanation:
To find the area, multiply the two different side lengths together.
Answer:
Perimeter: 52 Area: 181-16i?
Step-by-step explanation:
<u>Perimeter</u>
The formula for perimeter is 2l+2w, so you plug in the binomials they give you:
2(11-4i)+2(15+4i)
expand:
22-8i+30+8i
combine like terms (which cancels out 8i and -8i):
22+30=52
<u>Area</u>
"i" is not a real number and thus should not be part of the area here, meaning this answer as it is is wrong and I don't know how one would change that.
Here's what I did to get 181-16i, in any case:
The formula for area is l*w, so I plugged in the numbers:
(11-4i)(15+4i)
expanded:
165+44i-60i-16i*i
and combined like terms:
181-16i
*i is , so =-1 and -1*-16=16.
Answer:
y=3.5
Step-by-step explanation:
<u>7</u><u>y</u><u>-</u><u>4</u><u>.</u><u>6</u><u>-</u><u>6</u><u>y</u>
<u>4</u><u>.</u><u>5</u><u>=</u><u>7</u><u>y</u><u>+</u><u>6</u><u>y</u>
<u>4</u><u>.</u><u>5</u><u>=</u><u>1</u><u>3</u>y
4.5. 4.5
y=3.5
The period is 2.
Normally the period of sin(x) is 2pi, but the pi inside the sin(pix) is a horizontal compression by a factor of 1/pi. So 2pi·1/pi = 2
The "1/2" and "+3" do not impact the period. Those just impact the amplitude (vertical aspect) of the graph.
I would need to see it other wise how would i help you i do not know the other information i need to solve it
