Answer:
the y-intercept is 15 which is the initial total depth of the snow at t=0 hours.
The rate of melting is 1.5inches per hour. It will take 10 hours at the melting rate given of 1.5 to melt all the snow.
Step-by-step explanation:
the y-intercept is 15, and it might mean that the total depth of the snow is 15 inches.
The rate of melting is 1.5inches per hour.
At time = 0, S=15 - 1.5t = 15 - 1.5(0) = 15 inches to start
At time = 10, S=15 - 1.5t = 15 - 1.5(10) = 0 inches; meaning all snow has melted and it took 10 hours.
Sin x = b/c
Cos x = a/c
Tan x = b/a
Answer:
Step-by-step explanation:
1)
y = 5x-4 when x=5
y = 5*5-4
y = 25-4
y = 21
y = -2/5x + 3/8 when x = 1/3
y = -2/5 * 1/3 + 3/8
y = -2/15 + 3/8
y = -6/120
y = -1/20
y = 3x + 12 when x = 4
y = 3*4 + 12
y = 12 + 12
y = 24
Answer:
A = 190 inches^2
Step-by-step explanation:
The total area would be area for a rectangle + <em>half</em> the area of a circle:
Area for a rectangle:
A = l x w
A = 12 x 15
A = 180
Area for half of the circle:
A =
Total area: Rectangle area + half of the circle area
= 180 + 9.8 = 189.8 = 190 inches^2
