Answer:
x=80 degree
Step-by-step explanation:
(x-5)+(x-6)+(2x-7)+x+(2x-2)=540 degree (sum of interior angles of a pentagon)
x-5+x-6+2x-7+x+2x-2=540
7x-20=540
7x=540+20
x=560/7
x=80 degree
Answer:p/6
Step-by-step explanation:
well 3x15= 45 and 15x17= 255 so 45+255= 300
The expected value is $38.46.
The probability of drawing a 10 from any suit is 4/52. Multiply this by the earnings, 500:
4/52(500) = 2000/52 = 38.46
Answer:
I guess that you want to know the transformations:
We start with:
f(x) = y = 4*x + 3
a)the transformed function is:
f(x) = y = -4*x - 3
So the sign changed.
This means that we go from (x, y) to (x, - y)
This is a reflection over the x-axis which changes the sin of the y component.
b) Now we go to f(x) = 4*x + 3
So the coefficient in the leading term changed.
This is a horizontal contraction:
A horizontal contraction of factor K for the function g(x) is: g(K*x)
In our case, we have:
f(K*x) = 4*(k*x) + 3 = x + 3
4*k*x = x
4*k = 1
k = 1/4
Then the transformation is an horizontal contraction of scale factor 1/4.
