If f(x) = 3x and mc010-1.jpg which expression could be used to verify that g(x) is the inverse of f(x)?

saul85 [17]

You could subsitute g(x) for x in f(x) and if you get x as a result, then that is indeed the inverse

ex
if
f(x)=x-2
the inverse which is g(x) is
g(x)=x+2 because if you did
f(g(x)) then you would get
f(g(x))=(2+x)-2=2-2+x=x

What is a=h(b+c) (solve for b)

frosja888 [35]

1. a=h(b+c)
2. distribute the h:
   a=hb+hc
3. move the 'hb' to the left:
   a - hb = hc
4. subtract the a from both sides:
   -hb = hc - a
5. divide both sides by -h to isolate b:
      b = -hc+a/h

Can anybody help me please

GREYUIT [131]

Question 7: Option 1: x = 33.5°

Question 8: Option 3: x = 14.0°

Step-by-step explanation:

Question 7:

In the given figure, the value of perpendicular and hypotenuse is given, so we have to use any trigonometric ratio to find the value of angle as the given triangle is a right-angled triangle

So,

Perpendicular = P = 32

Hypotenuse = H = 58

So,

$sin\ x = \frac{P}{H}\\sin\ x = \frac{32}{58}\\sin\ x = 0.5517\\x = sin^{-1} ( 0.5517)\\x =33.48$

Rounding off to nearest tenth

x = 33.5°

Question 8:

In the given figure, the value of Base and Perpendicular is given, we will use tangent trigonometric ratio to find the value of x

So,

Perpendicular = P = 5

Base = B = 20

So,

$tan\ x = \frac{P}{B}\\tan\ x = \frac{5}{20}\\tan\ x = 0.25\\x = tan^{-1} (0.25)\\x = 14.036$

Rounding off to nearest tenth

x = 14.0°
