Split it up into 4 separate shapes as shown in the attached picture:
shape 1 and 3 are identical triangles
area = 1/2 x B x H
area = 1/2 x 2 x 2 = 2 square cm each ( there are 2 so 2+2= 4 square cm for shape 1 & 3)
shape 2 is a rectangle area = L x w = 4*2 = 8 square cm
shape 4 is a triangle
area = 1/2 x b x h = 1/2 x 8 x 5.75 = 23 square cm
total area add all the shapes together: 4 + 8 + 23 =
35 square cm
Answer:
∠DEF =56°
Step-by-step explanation:
We are given that arc DEF = 248°
So, arc DCF = 360°-248°
arc DCF = 112°
Now we are required to find the ∠DEF.
So, we will use Inscribed angle theorem.
Inscribed angle theorem: The measure of an inscribed angle is equal to one-half the measure of its intercepted arc.
Intercepted arc = arc DCF = 112°
Inscribed angle = ∠DEF
⇒∠DEF =
⇒∠DEF =
⇒∠DEF =56°
Hence the measure of ∠DEF =56°

Answer:
f(x) = 2(x +2)^2(x -5)
Step-by-step explanation:
The root at x=-2 has even multiplicity. The curve is not flat there, so the multiplicity is 2, not higher. The root at x=5 has multiplicity 1. Then the factored form of this cubic is ...
f(x) = a(x +2)^2·(x -5)
The local minimum when a=1 is about -50, so we judge the leading coefficient to be 2. The desired function is ...
f(x) = 2(x +2)^2(x -5)
