Answer: K = 6
Step-by-step explanation:
If you find the inverse of the inverse function, it will return back to initial function.
The inverse of r^-1 (x) will give r(x).
To find the inverse of r^-1(x), let it be equal to y. Interchange y and x for each other and make y the subject of formula. That is,
Y = 2x^2 - 14
Interchange y for x
X = 2y^2 - 14
2y^2 = x + 14
Y^2 = x/2 + 14/2
Square both side
Y = sqrt ( x/2 + 7 )
It is only when K = 6, that will can get the value above.
Answer:
∠ ABC = 67°
Step-by-step explanation:
the angle between a tangent and a chord is equal to the angle in the opposite segment, that is
∠ ABC = ∠EAC = 67°
A box plot is made up of five numbers, also known as the five number summary: min, Q1, med, Q3, max. Q1 and Q3 can be found by looking at the lines one space out from the middle, making up the outside of the box.
To find the IQR, we need to subtract Q1 from Q3.
A: 70 - 60 = 10
B: 85 - 60 = 25
C: 80 - 70 = 10
D: 75 - 65 = 10
The box plot with the largest IQR is B.
Hope this helps!! :)
Each ounce of egg contains 40 milligrams of protein and 20 milligrams of vitamin B. Each ounce of fish contains 50 milligrams of protein and 10 milligrams of vitamin B
Needs 580 and 200
280 140
300 60
so, 7 eggs 6 fish
Reciprocal of -32/7 = -7/32
