Answer:

C. 60%

Step-by-step explanation:

<u>Consider 1st row of table</u>

Total Price = P= 22.50

Discount=D=13.50

Percent discount=(D/P) x 100

                           =(13.5/22.5) x 100

                          = 60%

<u>Consider 2nd row of table</u>

Total Price = P= 27

Discount=D=16.20

Percent discount=(D/P) x 100

                           =(16.2/27) x 100

                          = 60%

Now we know discount rate is r=60%

Find f(2) and f(a+h) when f(x)=3x^2+2x+4
wolverine [178]
F(2) = 3(2)^2 + 2(2) + 4

= 3(4) + 4 + 4

= 12 + 8

f(2) = 20

f(a+h) = 3(a+h)^2 + 2(a+h) + 4

= 3(a^2 + 2ah + h^2) + 2a + 2h + 4

f(a+h) = 3a^2 + 6ah + 3h^2 + 2a + 2h + 4

Use the identity (x+y)(x2−xy+y2)=x3+y3 to find the sum of two numbers if the product of the numbers is 28, the sum of the square
fgiga [73]

Answer:

Step-by-step explanation:

1) f(x) = x+y , xy = 49 --> f(x) = x+49/x

f '(x) = 1-49/x2 , x = ±√49 , choose x = +7

y = 49/x = 7

smaller = 7

larger = 7

2) Vertical Distance is difference between the two functions

V(x) = x+56 - x2, V '(x) = 1 -2x --> x = 1/2 --> V(1/2) = 56.25 <---Max Vertical distance

Boundary at -7 and 8 are less

3) I googled the equation, it is really y(n) = kn/(49+n2)

y '(n) = (k(49+n2) - 2kn2)/(49+n2) , Setting to zero, k(49+n2) -2kn2 = 0 , n = 7

4) Let x and y be the sides of the rectangle. A = xy = 37.5 Million or y = 37.5/x

The length of the fences is f(x) = 2x + 3y = 2x+112.5/x

f '(x) = 2-112.5/x2 --> x = √56.5 = 7.5 and y = 37.5/7.5 = 5 then scale by √Million

smaller = 5000 ft and larger = 7500 ft

this took me ages to work out so hopefully it helped

On a piece of paper, graph y &lt; 3/4 x+2 Then determine which answer matches the graph drew.
OleMash [197]

Step-by-step explanation:

Given inequality is y.

To graph that inequality, first we need to graph the line y=\frac{3}{4}x+2. Then shade it for the inequality symbol <.

Graphing line can be done using two points.

plug x=0 into y=\frac{3}{4}x+2, we get:

y=\frac{3}{4}*0+2=2

Hence first point is (0,2)

Similarly plug any random number for x say x=4, we get:

y=\frac{3}{4}*4+2=5

Hence first point is (4,5).

Now we just need to graph both points and join them by a dotted line. because we have < not <=.

Next part is to test for shading.

Which can be done using any test point which is not on the given line. Say (0,0)

plug x=0,y=0 into y.

0

0

0<2

which is true, hence shading will be in direction of test point (0,0).

Hence final answer will be the choice which looks like the graph attached below;
