4/7 x 21/40

This problem can be reduced.

1/1 x 3/10

In reducing this we cross multiply 4 into 4 is equal to 1, 4 into 40 is equal to 10 and 7 into 7 is equal to 1, 7 into 21 is equal to 3.

Answer = 3/10

Use the function f(x) to answer the questions.
frutty [35]

<u>Part A</u>

<u />-16x^2 + 60x+16=0\\\\4x^2 - 15x-4=0\\\\(4x+1)(x-4)=0\\\\x=-\frac{1}{4}, 4

<u>Part B</u>

The vertex of the graph will be a maximum because the leading coefficient is negative.

The x coordinate of the vertex is -\frac{60}{2(-16)}=\frac{15}{8}.

When x=15/8, f\left(\frac{15}{8} \right)=\frac{289}{4}.

So, the vertex has coordinates \left(\frac{15}{8}, \frac{289}{4} \right)

<u>Part C</u>

Plot the two x-intercepts and the vertex and then draw a curve in the shape of a parabola passing through them.

The graph is in the attached image.

By what percent will the product of two numbers change, if the first number increases by 70%, while the second number decreases
FinnZ [79.3K]

Answer:

2%

Step-by-step explanation:

Let x be the first number

It increases by 70 %

The new number is

m = x+ .70x

   = 1.7x

Let y be the second number

It decreases by 40 %

The new number is

n =y - .40 y

  = .6y


The product of the original numbers is xy

The product of the new number is

mn = (1.7x * .6y) = 1.02xy

The new number is larger than the old number so it is an increase.

Percent increase is  new - original divided by original  times 100%

Percent increase = (1.02 xy - xy)

                                -----------------  * 100%

                                 xy  

                           = .02 xy

                                ------- * 100 %

                                 xy  

                            = .02 * 100 %

                             = 2%
