Area of triangle ABC can be found using the formula ¹/₂ × b × c × sin (A)
Substitute b = 9, c = 7, and m∠A = 66° into the formula gives
Area = 9 × 7 × sin 66° = 57.55
ANSWER: D
38:66 because the amount of 1/2 is the amount of 2.5
Answer:
c) 5, -5
Step-by-step explanation:
5 + (-5)
= 5 - 5
= 0
Answer:
30.857 feet
Step-by-step explanation:
It is given that the diameter of the half-circular garden is 12 feet.
Therefore, the perimeter of the garden will be = length of the half-circular arc + diameter of the garden.
Now, length of the half-circular arc = πr
Given Diameter = 12 ft.
So, radius = 6 ft.
So, length of the half-circular arc = πr = feet.
Hence, perimeter of the garden = 18.857 + 12 = 30.857 feet.
Therefore, 30.857 feet distance will be covered if I walk around the entire garden. (Answer)
F(x)=(2x)^2 Find f(-4)
this is a function notation, if you have f(-4) you need to fill the in to (X) on the left had side.
So F(x)=((2(-4))^2,Multiply what is in side the() and that is-12(postive x negiavtive is negative), Then we need to square that and it 144. so the answer is F(-4)=144
