Answer:
Step-by-step explanation:
By inscribed angle theorem:
![m\angle R = \frac{1}{2} [360 \degree - (120 \degree + 140 \degree)] \\ \\ m\angle R = \frac{1}{2} [360 \degree -260 \degree] \\ \\ m\angle R = \frac{1}{2} \times 100 \degree \\ \\ m\angle R = 50 \degree \\ \\](https://tex.z-dn.net/?f=m%5Cangle%20R%20%20%3D%20%20%5Cfrac%7B1%7D%7B2%7D%20%5B360%20%5Cdegree%20-%20%28120%20%5Cdegree%20%2B%20140%20%5Cdegree%29%5D%20%20%5C%5C%20%20%5C%5C%20m%5Cangle%20R%20%20%3D%20%20%5Cfrac%7B1%7D%7B2%7D%20%5B360%20%5Cdegree%20-260%20%5Cdegree%5D%20%20%5C%5C%20%20%5C%5C%20%20m%5Cangle%20R%20%20%3D%20%20%5Cfrac%7B1%7D%7B2%7D%20%5Ctimes%20100%20%5Cdegree%20%20%5C%5C%20%20%5C%5C%20%20m%5Cangle%20R%20%20%3D%2050%20%5Cdegree%20%20%5C%5C%20%20%5C%5C%20)
She could work as a trash person, taking garbage out and destroying it. She could work as a chef, cooking food for hungry people. She could be a homeless shelter worker, and help people find homes.
Huma services cluster is things that you would do for humans outside. Things like trash people take out other's trash a dispose of it all. Making them a human services person!
Step-by-step explanation:
if parabola has a vertex not in x-axis, it should have 2 x intercept
x-vertex = -2
first x intercept = 3
second x intercept should -7
so the equation will like this
y = a(x-x1)(x-x2)
y = a (x-3)(x+7)
y = a(x² + 4x - 21)
5 = a((-2)² + 4(-2) - 21)
5 = a(4 - 8 - 21)
5 = a(-25)
a = 5/(-25)
a = -1/5
then the equation is
y = (-1/5)(x² - 4x - 21)
or you can write as
y = -x²/5 + 4x/5 + 21/5
or as this one
5y = -x² + 4x + 21
Answer:
33b - 8
Step-by-step explanation:
You solve for the perimeter like you would for any other shape by adding all the sides
The perimeter is side A + side B + side C.
so it's 9b+8 + 12b-8 + 12b-8
Add all the like terms
9b + 12 b + 12b = 33b
8 - 8 - 8= -8
= 33b -8
A)We have been given →
Hieght of trough = 5m
length of trough = 6m
Breadth of trough = 4m
so , As the top is opened for feeding animals.
Area of base = length× Breadth
= (6×4) m²
= 24 m²
Area of Front and back face = Hieght × length
= (5×6) m²
= 30m²
Area of side faces = hieght × Breadth
= (5×4) m²
= 20 m²
____________________________________
B)Total Surface area of trough will be given by formula - 2(lb+bh+hl)
= 2{(6×4)+(4×5)+(5×6)}
= 2{24+20+30}
= 2×74
= 148 m²
As we have been told top is open , so we will deduct top from Total surface Area to obtain Surface area →
(148-24) m²
(Area of top will be same as base area , that is 24m² as we have solved in A)
= 124m²
Answer→ Surface area of trough is 124m²
