Use Sin,cosine, and tangent that should help you.
Answer:
40 in.^2
Step-by-step explanation:
Let's name the 2 shaded triangles: The left one is T1 and the right one is T2.
The area of a right triangle can be found using the equation (a*b)/2.
The 2 legs of T1 are 8 in. and 6 in. (from 10 - 4)
Area of T1 = = 24 in.^2
The 2 legs of T2 are 8 in. and 4 in.
Area of T2 = = 16 in.^2
Area of shaded region = 16 + 24 = 40 in.^2
When two lines are perpendicular to one another, their slopes multiplied together is always going to be -1.
With this in mind, set up the following equation:
m₁ * m₂ = -1
So
is your slope.
Since y = (-1)x + b, plug in y and x to solve for b, using the point (10, -8);
So your equation is
y = -x + 2
Answer:
9.6
Step-by-step explanation:
So we have to calculate 1/4 of 12.8 miles to see how many miles Johnny already traveled: * 12.8 = 3.2
Sp Johnny stopped when he was 3.2 miles there.
Next we subtract to get how many miles Johnny has left: 12.8 - 3.2 = 9.6
Johnny has 9.6 miles left to go
