Answer:

The graph of original function is shown below.

Step-by-step explanation:

The graph of the inverse function is given.

From the given graph it is clear that the graph of inverse function is in an exponential function that passes through the points (0,1) and (1,3).

Let the inverse function be

y=ab^x

Put x=0 and y=1 in the above equation.

1=ab^0\Rightarrow a=1

Put a=1, x=1 and y=3 in the above equation.

3=(1)b^1\Rightarrow b=3

So the inverse function is

y=(3)^x

Interchange x and y.

x=(3)^y

Taking log both the sides.

logx=log(3)^y

logx=ylog(3)               [\because logx^a=alog(x)]

Divide both the sides by log3.

\frac{logx}{log3}=y      

log_3x=y                     [\because log_ab=\frac{log_mb}{log_ma}]

The original function is

y=log_3x

The graph of original function is the mirror image of inverse function across the line y=x.

Therefore the graph of original function is shown below.

Lana's little sister needs to take a bubble bath. The package says to put in a drop of bubble bath for every half gallon of wate
Stels [109]

Answer:

Lana can put 24 drops of bubble bath for her sister

Step-by-step explanation:

If package says to put in a drop of bubble bath for every half gallon of water in the bath tub.

If the bathtub can hold 12 gallons of water

There are 12÷1/2 gallon

=12×2/1

=24

It means there are 24 half gallons in the bathtub

If every half gallon of water requires a drop of the bubble bath

Then,

24 half gallons of water requires 24 drops of the bubble bath

Someone help me solve this problem
katrin [286]

Same-side interior angles where a transversal crosses parallel lines are supplementary:

  • 6y +4y = 180
  • 90 +5x = 180

The solutions to these equations can probably be done in your head:

  • y = 180/(6+4) = 18
  • x = (180-90)/5 = 18

The angles at the bottom of the figure, shown as different, are actually the same: 90°.

The angles at the top of the figure, shown as the same, are actually different: 108° on the left, 72° on the right.

true or false:the points (6,13),(21,33),(99,137)all lie on the-same line. the equation of the line is y=4/3x +5
Anit [1.1K]

The answer is true.

Step-by-step explanation:

To find the points all lie on the same line, we need to substitute the points in the equation of the line, to determine if the values on both sides of the equation are equal.

Substituting the point (6,13) in the equation of the line, we get,

\begin{aligned}y &=\frac{4}{3} x+5 \\13 &=\frac{4}{3}(6)+5 \\&=4(2)+5 \\&=8+5 \\13 &=13\end{aligned}

Thus, the values on both sides are equal. The point (6,13) lie on the same line.

Substituting the point (21,33) in the equation of the line, we get,

\begin{aligned}y &=\frac{4}{3} x+5 \\33 &=\frac{4}{3}(21)+5 \\&=4(7)+5 \\&=28+5 \\33 &=33\end{aligned}

Thus, the values on both sides are equal. The point (21,33) lie on the same line.

Substituting the point (99,137) in the equation of the line, we get,

\begin{aligned}y &=\frac{4}{3} x+5 \\137 &=\frac{4}{3}(99)+5 \\&=4(33)+5 \\&=132+5 \\137 &=137\end{aligned}

Thus, the values on both sides are equal. The point (99,137) lie on the same line.

Thus, all the three points lie on the same plane.

Hence, the answer is true.
