f(x) = 7 is a even function
<em><u>Solution:</u></em>
Given that we have to find the even function
A function is even if and only if f(–x) = f(x)
<em><u>Steps to follow:</u></em>
Replace x with -x and compare the result to f(x). If f(-x) = f(x), the function is even.
If f(-x) = - f(x), the function is odd.
If f(-x) ≠ f(x) and f(-x) ≠ -f(x), the function is neither even nor odd.
<h3>Option 1</h3>
Substitute x = -x in above function
Thus
So this is not a even function
<h3>Option 2</h3>
f(x) = 8x
Substitute x = -x in above function
f(-x) = 8(-x) = -8x
Thus
So this is not a even function
<h3>Option 3</h3>
Substitute x = -x in above function
Thus
So this is not a even function
<h3>Option 4</h3>
f(x) = 7
f(-x) = 7
Thus f(-x) = f(x)
Thus it is a even function
Step-by-step explanation:
Area of remaining paper
= Area of rectangle - 2 * Area of semicircle
= Area of rectange - Area of circle
= (4in * 8in) - (π * 2in * 2in)
= 32in² - 4πin²
= 19.44in². (A)
<span>Cylinder Volume = </span><span>π <span>• r² • height
</span></span>
<span>r² = Cylinder Volume / <span>π <span>• height
</span></span></span>
r² = 226.08 / (<span> π <span>• 8 )
r</span></span><span>² = </span><span><span>8.9954373836
</span>
r = </span><span><span><span>2.9992394675

So we distribute the 2 to the 3m and the +4 so
2*3m=6m
2*4=8
6m+8
we then distribute the 3 to the m and the - 5
3*m=3m
3*-5=-15 ((+) times (+) or (-) times (-)=(+), (-) times (+) or (+) times (-)=(-))
3m-15
add 6m+8 and 3m-15
6m+8+3m-15
add like terms (m terms + m terms and number + numbers)
6+3=9 so
3m+6m=9m
9m-7
