1 answer:
When you multiply numbers with the same base and exponents, you just add the exponents together. In the case of the first question:
*
=
When dividing, subtract the exponents instead, and when there's an exponent outside the parentheses the way it is on the 3rd question, multiply them together.
Hope this helps! :)

Answer:
The base and height of the solid is 5.5cm
<em></em>
Step-by-step explanation:
Given
Required
Determine the dimensions that maximizes the volume
Let the base dimension be x and the height be h
The volume is calculated as:
181.5 =x^2h
The surface area (S) is calculated as this:
Substitute 181.5 for S
Make h the subject:
Substitute in
To get the maximum, we differentiate V with respect to t and set the differentiation to 0
Set to 0
Multiply through by 4
Recall that:
So, we have:
<em>Hence, the base and height of the solid is 5.5cm</em>
Answer:
1. 4
Step-by-step explanation:
For question 1, you need to know the ratio between the recipe and the amount in question.
So if in the recipe, it says it uses 3/4 cup of diced ham, and the question uses 1 cup of diced ham, you can divide 1 by 3/4 to get 4/3. This is how many times bigger the amount used in the question than the recipe.
Then it asks for how many cups of potatoes, to do this, you look at the recipe and how many potatoes it uses: 3.5 cups
To solve it then, you just do 3.5 x 4/3 to get 4 cups of potatoes
There's your answer.
