Answer:

Step 1 : 9=72 & 8=56

So, in 8 & 9, values are 72 & 56 resp. The gap between the two are

72 - 56 = 16

Step 2 : 8 = 56 & 7 = 42

So, in 8 & 7, values are 56 & 42 resp. The gap between the two are

56 - 42 = 14

Step 3 : 7 = 42 & 6 = 30

So, in 7 & 6, values are 42 & 30 resp. The gap between the two are

42 - 30 = 12

Step 4 : 6 = 30 & 5 = 20

So, in 6 & 5, values are 30 & 20 resp. The gap between the two are

30 - 20 = 10

Step 5 :

From steps 1, 2, 3 & 4 its’s clear that the gap between the next sequence is 8.

4 = x

So, now

20 - x = 8

X = 20 – 8

X = 4

So, 4 = 12

Now, to find 3 = y, we know that the gap between the next sequence is 6.

So, now

12 - y = 6

Y = 12 – 6

Y = 6

So, 3=6

Find derivative of the following problem ?

stepan [7]

Let u = x.lnx, , w= x and t = lnx; w' =1 ; t' = 1/x

f(x) = e^(x.lnx) ; f(u) = e^(u); f'(u) = u'.e^(u)

let' find the derivative u' of u
u = w.t
u'= w't + t'w; u' = lnx + x/x = lnx+1

u' = x+1 and f'(u) = ln(x+1).e^(xlnx)

finally the derivative of f(x) =ln(x+1).e^(x.lnx) + 2x

5x-y=7

seropon [69]

Answer:

see graph of y = 5x - 7

Step-by-step explanation:

If graphing is the task, you should rewrite the equation in a y = ax + b form. All straight lines can be described in this form, only the a and b determine which line it is.

Your equation 5x-y=7 has the 5x on the left side, so lets move it to the right. It will get a negative sign (this is the same as subtracting 5x like you did in your picture)

5x - y = 7

-y = 7 - 5x

Now we still have the -y which should be a +y. So we multiply left and right with -1 and get:

y = -7 + 5x

If we swap the -y and 5x (we can, because they are just an addition), we get:

y = 5x - 7

Now the equation is in its "normal" form. It's like the y = ax + b with a and b chosen as a=5 and b=-7.

The normal form is handy because you can immediately see the slope is 5 and the intersection with the y-axis is at y=-7.

ted wants to buy a skateboard that costs $59.00, but is on sale for 30% off. How much money will he save

STatiana [176]

Answer:

$17.70

Step-by-step explanation:

Hi,

What you want to do is to find 30% of $59

First, you convert 30% into decimal form by dividing it by 100

30%=0.3

Next, you want to find 30% of 59, so what you do is you take the new decimal form and multiply it by 59

0.3×59=17.7

Ted is saving $17.70
