D
Step-by-step explanation:
Sin(45) .70 rounded is 71
Answer: -2
Step-by-step explanation: The y-intercept of a line is the point where the graph crosses or intersects the y-axis.
In this case, the line crosses the y-axis 2 units down from the
origin and we can write the coordinates of the point as (0, -2).
So the answer is -2.
Answer:
A. parallel lines
You can also use the app desmos to help you graph equations.
The lawn area of uniform width can be written as follows:
A = (40 + 2x) * (35 + 2x) - (40) * (35)
Where,
x: width of the lawn
Substituting the value of the area we have:
316 = (40 + 2x) * (35 + 2x) - (40) * (35)
Rewriting:
316 = 1400 + 80x + 70x + 4x ^ 2 - 1400
Rewriting we have:
4x ^ 2 + 150x - 316 = 0
Solving the polynomial we have:
x1 = - 79/2
x2 = 2
Taking the positive root we have that the grass width des:
x = 2 yards
Answer:
The width of the lawn that surrounds the garden is:
x = 2 yards
