Answer:
y = 1/2x -3
Step-by-step explanation:
We can use the slope intercept form the equation for a line
y = mx+b where m is the slope and b is the y intercept
y = 1/2x +b
Substitute the point into the equation
-4 = 1/2(-2) +b
-4 = -1+b
Add 1 to each side
-4 +1 = -1 +1+b
-3 = b
Writing the equation
y = 1/2x -3
The original price of the TV was $1327.07
Answer:
£21
Step-by-step explanation:
Cost of 18 drinks = £54
Cost of 1 drink
= Cost of 18 drinks/18
= £54/18
= £3
Cost of 7 drinks
= Cost of 1 drink × 7
= £3 × 7
= £21
Answer:
a. θ = 6t
b. 1.048 minutes
c. y = 54sin(6t)
Step-by-step explanation:
diameter d = 108 foot
distance above the ground = 58 feet
a.) expression to represent number of radians
radian = 6 rad/min
θ = wt
w = 6
θ = 6t
t is in minutes
b.) we are to find the time period for one full revolution
time period = 2π/6
π = 22/7
= 1.048 minutes
c. Expression showing Justins height above the ground
y = rsinθ -----(1)
θ = wt = 6t
we find the radius r
diameter = 2 * radius
108 = 2r
r = 108/2
= 54 foot
we put these values in the equation 1 above
y = 54sin(6t)
