HIAB
1)H, 2)I, 3)A, 4)B.

When there is only points and no lines, to find domain, you give the x values only, and to find the range you give the y values only.

When there is a line, for domain you go from left to right, and for range you go from bottom to top. The arrow indicates that the line is continuous, and so the second values for domain and range are infinity because we do not know the value.

How are number lines and the coordinate plane related?

schepotkina [342]

a coordinate plane is a two-dimensional number line where the vertical line is called the y-axis and the horizontal is called the x-axis. And a number line is
a line on which numbers are marked at intervals, used to illustrate simple numerical operations. So how are the related........?

Please please help me in these questions

boyakko [2]

a. a=40° (alternate interior angles)

b+40°=180°( supplementary angles)

b=140°

c= d= 140°( vertically opposite angles)

d=b=140°( corresponding angles)

b. 2a+120°=180° (supplementary angles)

2a=60°

a=30°

c. a+110°=180°( supplementary angles)

a=70°

b+70°=180°( supplementary angles)

b=110°

c+110°=180°( supplementary angles)

c=70°

c=d=70( corresponding angles)

What is the volume of the composite figure shown? (Use 3.14 for π.)

Nimfa-mama [501]

$The\ volume\ of\ the\ cone:V_1=\frac{1}{3}\pi r^2 H\\(r-a\ radius;\ H-height)\\------------------\\r=7ft;\ H=7ft\\\\V_1=\frac{1}{3}\pi\cdot7^2\cdot7=\frac{1}{3}\pi\cdot343=\frac{343}{3}\pi\ (ft^2)\\-------------------\\The\ volume\ of\ the\ cylinder:V_2=\pi r^2 H\\(r-a\ radius;\ H-height)\\-------------------\\r=7ft;\ H=6ft\\\\V_2=\pi\cdot7^2\cdot6=294\pi\ (ft^3)\\------------------------\\The\ volume\ of\ the\ composite\ figure: V_F=V_1+V_2$

$V_F=\frac{343}{3}\pi+294\pi=\frac{343}{3}\pi+\frac{294\cdot3}{3}\pi=\frac{343}{3}\pi+\frac{882}{3}\pi=\boxed{\frac{1225}{3}\pi\ (ft^3)}\\\\\approx\frac{1225}{3}\cdot3.14}=\frac{3846.5}{3}\approx\boxed{1,282.17\ (ft^3)}\leftarrow answer$
