Mr. Smith has an online cooking show. Before he films an episode about baking the perfect pound cake, he prepares his ingredient
Leviafan [203]

Answer:

15

Step-by-step explanation:

We are told in the question that:

Mr Smith's recipe calls for 2 1/2 cups of sugar for the cake and 1 1/4 cups of sugar for the vanilla glaze.

Step 1

We add up the total amount of sugar he would need

2 1/2 + 1 1/4

(2 + 1) + (1/2 + 1/4)

= 3 + (2 + 1/4)

= 3 3/4 cups of sugar.

Step 2

How many 1/4 cup scoops of sugar does he need?

This is calculated as:

3 3/4 cups of sugar ÷ 1/4

= 15/4 ÷ 1/4

= 15/4 × 4

= 15

Therefore, he would be needing 15 , 1/4 cup scoop of sugar

Recall that

\mathcal L_s\{t^ne^{ct}\}=\dfrac{n!}{(s-c)^{n+1}}

Then

F(s)=\dfrac2{(s-5)^3}+\dfrac4{(s-5)^2}+\dfrac7{s-5}
