The first part of the answer is 20x+9
Second part is 4a-6b
Answer:
y intercept (0;4)
Step-by-step explanation:
let x = 0 because the graph will intersect the y-axis at the value of 0 for the x-axis
Linear equation: y = mx + c
m = slope
c = y-intercept
Answer:
122.5 lbs
Step-by-step explanation:
The relation between force, wind speed, and area can be written ...
f = ks²a
for some wind speed s and area a.
__
The constant of proportionality, k, can be found from the given data.
64.8 = k(18²)(500) . . . force in pounds, area in square feet, speed in mph
k = 64.8/(324×500) = 0.0004
__
Using the equation with the second set of data, we have ...
f = 0.0004(35²)(250) = 122.5 . . . . pounds
The force on the 250 square foot sail would be 122.5 pounds.
