First you find your slope which is rise/run, so, 1/3, and a line this way (/) is positive, so it's positive 1/3.
Then you see where it crosses the y axis: -1.
Plug that into y=mx+b giving you y=1/3x-1.
Your answer is D.
Is this multiple choice if so what are the options <span />
Answer:
Step-by-step explanation:
<u>In 4 seconds the rock will be at:</u>
- 2*4 = 8 in from the surface
<u>Add 5 feet to this to get the required distance:</u>
- 5 ft + 8 in = 5*12 in + 8 in = 68 in
Answer:
total area = 18.28 in.^2
perimeter = 16.28 cm
Step-by-step explanation:
Area:
The total area of the figure is the sim of the area of the rectangle and the area of the semicircle.
total area = LW + (1/2)(pi)r^2
total area = (4 in.)(3 in.) + (1/2)(3.14)(2 in.)^2
total area = 12 in.^2 + 6.28 in.^2
total area = 18.28 in.^2
Perimeter:
The perimeter of the figure is the sum of the lengths of the left side, bottom side, and right side of the rectangle and the circumference of the half circle.
perimeter = 3 cm + 4 cm + 3 cm + (1/2)(pi)d
perimeter = 10 + (1/2)(3.14)(4 cm)
perimeter = 10 + 6.28 cm
perimeter = 16.28 cm
