First we add all the angles together
x + 2x - 20 + 2x + 10 = 5x - 10
Now, you should know that all the angles in a triangle add up to 180°
180 = 5x - 10
Move the 10 to the other side
190 = 5x
Divide both sides by 5
x = 38
So the angles sizes in ascending order are
38 , 46 , 86
Answer:
Step-by-step explanation:
Given
Round 0 1 2 3
Points 25 75 225 675
Required
Determine the equation
Let n = rounds and p = points.
So, we have:
The above shows a geometric progression.
So, we solve using
In
n = 0 and p = 25
Substitute these values in
In
n = 1 and p = 75
Substitute these values in
Substitute 25 for a
Make b the subject
So, we have:
and
The equation becomes
Answer:
50.5
Step-by-step explanation:
Sooo first we calculate edf. 11/2= 5.5, 5.5x5=27.5
And then we do the other part.9/5=4, and 4x11.5=46, and we need to cut that in half cuz it’s a triangle 46/2=23. We add up the rectangle and the triangle: 27.5+23=50.5
dy/dx = 2xy
dy/y = (2x)dx
INT(1/y)dy = INT(2x)dx
ln y + c = x^2 + d
ln y = x^2 + constant
y = e^(x^2 + constant)
1 = e^constant ... so constant=0 ... so y = e^(x^2)
Verification:
y = e^(x^2)
dy/dx = 2x*e^(x^2) = 2xy
<span>and e^(0^2) = e^0 = 1
