The pair will have to be in two so that when you multiply it by four you will get your answer let me now if you need me to explain more
Answer:
26.52 cubic inches
Step-by-step explanation:
We need to find the volume of each box and then multiply by 3.
The volume of a cylinder is given as:
where r = radius
h = height
The height of each box is 5 inches and its radius is 0.75 inches.
Therefore, the volume of each box is:
V = 8.84 cubic inches
The volume of 3 boxes will therefore be:
V = 8.84 * 3 = 26.52 cubic inches
26.52 cubic inches of material is needed to make 3 boxes.
Amount of money Aisha receive from selling all of the bracelets is $33.25.
<u>Step-by-step explanation:</u>
In this question, its given that Aisha made bracelets for a craft fair. She spent $29.75 on supplies to make the bracelets. Each bracelet cost her about $0.85 to make. Aisha sells each bracelet for $0.10 more than it cost her to make. Let's calculate Number of bracelets Aisha made as .
Number =
⇒ Number =
⇒ Number =
⇒ Number =
Now , its given that Aisha sell these bracelets with $0.10 more then it cost her i.e. at $0.95 , Let's calculate selling price as :
Price =
Price = $33.25
Therefore, amount of money Aisha receive from selling all of the bracelets is $33.25.
The solution to the problem is as follows:
let y = asinx + bcosx
<span>
dy/dx = acosx - bsinx </span>
<span>
= 0 for max/min </span>
<span>
bsinx = acosx </span>
<span>
sinx/cosx = a/b </span>
<span>
tanx = a/b </span>
<span>
then the hypotenuse of the corresponding right-angled triangle is √(a^2 + b^2) </span>
<span>the max/min of y occurs when tanx = a/b </span>
<span>
then sinx = a/√(a^2 + b^2) and cosx = b/√(a^2 + b^2) </span>
<span>
y = a( a/√(a^2 + b^2)) + b( b/√(a^2 + b^2)) </span>
<span>
= (a^2 + b^2)/√(a^2 + b^2) </span>
<span>
= √(a^2 + b^2)</span>

Answer:
1. y=3x+2
It has a gradient of 3, and crosses the y-axis at 2
2.y= -1x +4
It is -1x, because of a negative slope
