Answer:
101.07ft^2
Step-by-step explanation:
Given data
radius= 5ft
h= 9ft
When the radius and height are both multiplied by 1/2
radius= 5/2ft = 2.5ft
height= 9/2 ft= 4.5ft
The expression for the surface area of the cone is
A=πr(r+√h^2+r^2)
Substiute
A= 3.142*2.5(2.5√4.5^2+2.5^2)
A= 7.855(2.5√20.25+6.25)
A= 7.855(2.5√26.5)
A= 7.855(2.5*5.147)
A=101.07 ft^2
Hence the surface area is 101.07ft^2
Okay, so first off, if you need to graph anything, I suggest Desmos, it's a website with an online graphing calculator. It saved my life for highschool geometry.
Now, to answer your question, your y-intercept is going to be at point (0,2). Your x-intercepts are going to be at points (-2,0) and (-4,0). Your point is at (-3,-1). And then your lines simply extend from there.
Hope this isn't too late to be helpful, good luck with your assignments.

Answer:
$55
Step-by-step explanation:
<u><em>Given:</em></u>
<em>A pair of shoes is $50, plus 10% tax. </em>
<u><em>To Find:</em></u>
<em>What is the total amount you will pay?</em>
<u><em>Solve:</em></u>
<em>Tax = Increase - Add on</em>
<em>Thus,</em>
<em>$50 × 10% = 5</em>
<em>$50 + 5 = $55</em>
<em>Hence, the total amount you will pay is $55.</em>

Answer:
x≥11
Step-by-step explanation:
2(4+x)+2(3x) ≥96
as at least means either greater than or equal to
now simplify as 2 multiplies 4+x
8+2x+6x ≥96
8+8x≥96take 8 on other side
8x≥96-8
8x≥88
x≥88/8
x≥11
