Answer:
we have the expression as;
1/sin u cos u
Step-by-step explanation:
tan u = sin u/cos u
cot u = cos u/sin u
Thus;
sin u/cos u + cos u/sin u
The lcm is sin u cos u
Thus, we have that;
(sin^2 u + cos^2 u)/sin u cos u
But ; sin^2 u + cos^2 u = 1
so we have ;
1/sin u cos u
2(3-1) ² / 1+1 x 3+3

<u>Answer:</u>
<em>101.6 feet</em>
<u>Step-by-step explanation:</u>
<em>First compute the perimeter of the first two windows: (3.4+5.2)*2=17.2</em>
<em>The perimeter of the four other windows: (3.6+4.8)*2=16.8</em>
<em>The total number of feet needed for the first two windows:</em>
<em>17.2*2 = 34.4 feet</em>
<em>The total number of feet needed for the four windows:</em>
<em>16.8*4 = 67.2 feet</em>
<em />
<em>The total number of feet needed is then: 34.4 + 67.2 = 101.6 feet.</em>
Answer:
A) y - 2 = 3(x+4)
Step-by-step explanation:
Given that the equation is a line with slope =m=3 and
a point on it (x1,y1) = (-4,2)
Any line having slope m and passing through (x1,y1) has equation in point slope form as
y-y1 = m(x-x1)
We are given here x1 =-4, y1 =2 and m =3
y-y1 = y-2 and x-x1 = x-(-4) = x+4
So equation is y-2 = 3(x+4)
Verify:
The line is y = 3x+12+2 = 3x+14
Hence slope =3 is verified
Substitute the point x =-4 and y =2
2 =3(-4)+14 = 2 is true
Thus verified
