Answer:
(-3,-4)
Step-by-step explanation:
You draw it...
So since we are reflecting across the x-axis, we want the x-coordinate to stay the same. We just need to take the opposite of y.
Ans. (-3,-4)
Answer:
First, break the shape into smaller shapes.
Bigger rectangle: 5m, 8m
Thin rectangle: 7m, 3m
Thinner rectangle: 8m, 2m
We will call the bigger rectangle <u>B</u>, the thin rectangle <u>R</u>, and the thinner rectangle <u>r</u>.
Step-by-step explanation:
B = 8 • 5 = 40
R = 7 • 3 = 21
r = 2 • 8 = 16
Add the areas together:
40 + 21 + 16 = 77
Therefore, the area is <u>77 meters.</u>
Answer:
6) B
7) D
Step-by-step explanation:
6)
The surface area of a cylinder is 2 * pi * r * (r + h)
SA = 2 * 3.14 * 3.6 * (3.6 + 8.5) = 2 * 3.14 * 3.6 * 12.1 = 273.6 cm^2
7)
The volume of a cylinder is pi * r^2 * h
V = 3.14 * (3.6)^2 * 8.5 = 345.9 cm^3
Answer:
<h2>X = 59°</h2>
Step-by-step explanation:
To find Angle X we use sine
sin∅ = opposite/ hypotenuse
From the question
WY is the opposite
WX is the hypotenuse
So we have
sin X = WY/ WX
sin X = 6/7
X = sin-¹ 6/7
X = 58.99
X = 59° to the nearest tenth
Hope this helps you
