Answer:
sinA=9/41
cosA=40/41
tanA=9/40
Step-by-step explanation:
a=9, b=40,c=41
sinA=a/c=9/41
cosA=b/c=40/41
tanA=a/b=9/40
The way it's written it's
Simplify the following:
7 X^3 + 4 X^2 + 2 X^2 + 3 X + X + 2 + 5
Grouping like terms, 7 X^3 + 4 X^2 + 2 X^2 + 3 X + X + 2 + 5 = 7 X^3 + (4 X^2 + 2 X^2) + (3 X + X) + (2 + 5):7 X^3 + (4 X^2 + 2 X^2) + (3 X + X) + (2 + 5)
4 X^2 + 2 X^2 = 6 X^2:
7 X^3 + 6 X^2 + (3 X + X) + (2 + 5)
3 X + X = 4 X:
7 X^3 + 6 X^2 + 4 X + (2 + 5)
2 + 5 = 7:Answer: 7 X^3 + 6 X^2 + 4 X + 7

Answer:
2 Minutes
Step-by-step explanation:
the first ratio is 5:10 since it is easier to work with big numbers let's start by multiplying it by 2 to get something
Now we have 10:20 we can divide this by 10 and get the ratio 1:2
1:2 equals 1 mile:2 minutes which is 1 mile in 2 minutes!
Have a nice day and I hope this helps!
Answer:
Step-by-step explanation:
<u>Distance From a Point to a Line</u>
Given a line with an equation
:
ax + by + c = 0
And the point
The distance from the line to the point is given by
The triangle has a vertex at (1,-2) and the base lies on the equation
x + y = 3
Rearranging:
x + y - 3 = 0
The altitude of the triangle is the distance from the point to the line.
The values to use in the formula of the distance are: a=1, b=1, c=-3, xo=1, yo=-2:
Rationalizing:
The altitude of the triangle is
