Answer:
perimeter ≈ 12.4 units
Step-by-step explanation:
The side adjacent to the angle is given. The relationships useful for the other two sides are ...
Tan = Opposite/Adjacent
Cos = Adjacent/Hypotenuse
From these, we have ...
opposite = 5·tan(22°) ≈ 2.02
hypotenuse = 5/cos(22°) ≈ 5.39
Then the perimeter is ...
P = a + b + c = 2.02 + 5 + 5.39 = 12.41
The perimeter of ∆ABC is about 12.4 units.
Answer:
40 people
Step-by-step explanation:
One for each person
(0,0) is the cost of 0 bags of peanuts. This is because the x-axis is labeled "Bags of Peanuts", and an x-value of 0 implies 0 bags of peanuts.
To find the zeros of a polynomial, you make every factored parentheses equal to zero. You basically make the other side equal to zero and solve for x.
So,
<u>Your zeros are x = 9, -12, 24</u>
So your answer is 3) 9, -12, 24
Answer:
(1,-4)
Step-by-step explanation:
First manipulate the second equation so that y is by itself
x-y=5
-y=-x+5
y=x-5
then substitute that y in for the y in the above equation and solve for y
y=-2x-2
x-5=-2x-2
3x-5=-2
3x=3
x=1
Now that you have the x-coordinate, find the y-coordinate by plugging in the x-value in either of the equations
y=-2x-2
y=-2(1)-2
y=-2-2
y=-4
I see that you're using deltamath, and I think for the graph questions, you could first place a point for the y-intercept of one of the equations, and then place another point that is on the graph of the equation. Once you plotted both lines, just see the point where they meet and that is where the two systems of equations meet.
