It's C the missing side is 9 units long so since cosine is adjacent divided by hypotenuse it would be 9/41
Step-by-step explanation:
The answer is the 2nd one, the denominator is greater than the numerator because if you add 2 AND x its gonna ge a bigger number than just x alone
Answer:
It's the last choice:
2x + y - 1 = 0.
Step-by-step explanation:
x - 2y - 3 = 0
Convert to slope-intercept form in order to find the slope:
-2y = -x + 3
y = 1/2x - 3/2
So the slope is 1/2. The slope of a line perpendicular to this is -1 / 1/2 = -2.
Using the point-slope form to find the required equation:
y - y1 = m(x - x1)
x = 4 and y = -7 so we have:
y + 7 = -2(x - 4)
y + 7 = -2x + 8
2x + y - 1 = 0 is the answer.
Answer:
31.5
Step-by-step explanation:
Area of the bases
<span>2π<span>r2</span>=2π∗784=1568π
</span>circumference of base
<span>2πr=56π
</span>extension of the height
<span>2πr∗h=56π∗48=2688π
</span>bases plus none base surface is total surface
<span><span>1568π+2688π=4256π</span></span>
