I think it’s 3 I’m not sure
Step-by-step explanation:
y = 3cos(x) - 5
Domain = 2sin(x)
Range = 5
I think the answer is 3/5
Answer: BC = 5.83
Step-by-step explanation:
Luckily, the triangle is placed on the graph nicely so we can count the legs of the triangle:
AB = 5
AC = 3
BC = ?
To find BC, we can simply use the Pythagorean Theorem:

5^2 + 3^2 = c^2
25 + 9 = c^2
34 = c^2
Now square root to find c, or BC.

c = 5.83 (rounded by nearest hundredth)
Distributive is
a(b+c)=ab+ac
ab+ac=a(b+c)
perimiter of a rectangle=distance around
we have
P=L+W+L+W if we go around
so
P=L+L+W+W
P=2L+2W
undistribute 2
P=2(L+W)
