HELP I WILL GIVE BRAINLEIST OR WHATEVER 50 POINTS​
Ilya [14]

answer:

a. scarf costs today = $6

b. scarf costs 3 days from now = $3

step-by-step explanation:

  • 1/2 off means you would multiply the amount by 1/2 then subtract

a. original price of scarf: $12

12 X 1/2 = 6

12 - 6 = 6

— scarf costs today = $6

  • do the same thing but this time it is a different number

b. 12 X 3/4 = 9

12 - 9 = 3

— scarf costs 3 days from now = $3

Use the limit theorem and the properties of limits to find the limit.<br> Picture provided below
sashaice [31]

Answer:

b. 1/2

Step-by-step explanation:

lim        (x -3)(x +2)

x-->-∞    ---------------

              2x^2 + x +1

= lim        (x^2 -3x +2x - 6)

x-->-∞    -----------------------

              2x^2 + x +1

= lim        (x^2 -x - 6)

x-->-∞    -----------------------

              2x^2 + x +1

When we plug in x = -∞, we get indeterminate form.

Now we have to use the L'hospital rule.

d/dx (x^2 - x - 6) = 2x -1

d/dx (2x^2 + x + 1) = 4x + 1

Now apply the limit

lim            (2x - 1) / (4x + 1)

x--->-∞

Here we have to degree of the numerator and the denominator of the same. In this case, if x --> -∞, we get the result as the coefficient of the leading term as the result.

According to the rule, we get

= 2/4

Which can simplified as 1/2

The answer is 1/2

Hope this will helpful.

Thank you.

Find QR. <br> A).12<br> B).-8<br> C).9<br> D).6
mihalych1998 [28]

Answer:

D. 6

Step-by-step explanation:

Let's first find x :-

\sf 3 + 2x + 22 = x + 17

  • \sf 2x + 25 = x + 17
  • \sf 2x - x = 17 - 25
  • \sf x =  - 8

Now that we found x, let's find QR :-

QR = 2x + 22

  • \sf QR = 2( - 8) + 22
  • \sf - 16 + 22
  • \sf 6

Therefore, QR = 6 !!!
