It seemed like the graduation speech would last forever. Tyler leaned over to his father and asked in a discreet whisper, ''What

time is it now?'' His father told him it was one-fourth of an hour after the last time he asked. If it was 1:15 p.m. the last time he asked, what time is it now?

Describe the graph of y=1/2x-10 -3 comapred to the graph of y= 1/x
saw5 [17]

The parent function is:

$y=\frac{1}{x}

The transformed function is:

$y=\frac{1}{2 x-10}-3

$y=\frac{1}{2(x-5)}-3

$y=\frac{1}{2}\left(\frac{1}{x-5}\right)-3

Comparison of simplified transformed function with the parent function:

  • The function multiplying by a number indicates dilation.
  • The function is being compressed in vertical direction by a factor of 2 if the number lies between 0 and 1.
  • Subtracting a number from x indicates a horizontal shift towards right.
  • That is the parent function is transformed 5 units to right.
  • Subtracting a number from the function indicates a downward shift.
  • That is the parent function is transformed 3 units down.

Hence the graph of y=\frac{1}{2 x-10}-3 is the graph of y=\frac{1}{x} stretched vertically, shifted right by 10 unit and shifted 3 unit down.

The image of the graph is attached below.

a businesswoman sells a bag for $52.32, thereby making a profit of 9% on the cost of her. calculate the selling price the busine
Veronika [31]

Answer: $57.6

Step-by-step explanation:

Given : A businesswoman sells a bag for $52.32.

Let cuurent selling price : SP = $52.32

As they are making 9% profit now.

That means SP= Cp +0.09 CP , where Cp is the cost price of bag.

i..e 52.32=Cp(1+0.09) \ \text{[Substituted value of SP in LHS and taking Cp common outside in RHS]}

\Rightarrow\ 52.32=Cp(1.09)\Rightarrow\ CP=\dfrac{52.32}{1.09}=48

i..e Cost price of bag = 48

Selling price to gain 20% profit = Cp+0.20CP

= CP(1+0.20)

=48 (1.20)

= 57.6

Hence, the  selling price the businesswoman should ask in order to make 20% profit​ = $57.6

Can you please help me with this! It's due in a couple hours.
castortr0y [4]

Answer:

f(2) = -5

Step-by-step explanation:

A point (x, y) lying on a function represents output value (y-value) of the function for any input value (x-value).

In other words y = f(x) for any input value of 'x'.  

From the graph attached,

For the input value x = 2,

Output value of the function is y = -5

Therefore, f(2) = -5 will be the answer.
