Answer:

f^-1(x) = ( x + -1 )³

Step-by-step explanation:

f(x) = ∛x + 1

y  = ∛x + 1

we have to make x the subject to find the inverse

y  = ∛x + 1

y - 1 = ∛x

( y - 1 )³ = x

so Inverse: f^-1(x) = ( x + -1 )³

Triangle A B C is shown. Angle B C A is a right angle. The length of hypotenuse B A is 9.8 inches, the length of C B is 6.3 inch
german

Answer:

\angle B=\cos^{-1}\left(\dfrac{6.3}{9.8}\right)\\ \\\angle B=\sin^{-1}\left(\dfrac{7.5}{9.8}\right)

Step-by-step explanation:

Consider right triangle ABC with right angle C.

In this triangle,

  • BA = 9.8 in
  • CB = 6.3 in
  • CA = 7.5 in

Write trigonometric functions:

\cos \angle B=\dfrac{BC}{AB}=\dfrac{6.3}{9.8}\\ \\\sin \angle B=\dfrac{AC}{AB}=\dfrac{7.5}{9.8}

Hence,

\angle B=\cos^{-1}\left(\dfrac{6.3}{9.8}\right)\\ \\\angle B=\sin^{-1}\left(\dfrac{7.5}{9.8}\right)

Having trouble with this one can somebody help?
Varvara68 [4.7K]
Form equation
y = mx + c
y = (rise/run).x + c
y = (11-1 / 3--2)x + c
y = 2x + c
11 = 2(3) + c
Find c (y-intercept)
11 - 6 = c
c = 5
Final equation of line
y = 2x + 5
Substitute given possible x-values in to find y-values
y = 2(1) + 5 = 7 (1,7)
y = 2(2) + 5 = 9 (2,9)
Therefore d is correct
