Answer:
[tex]\tan \left(\frac{\pi }{2}\right)[/tex]
Step-by-step explanation:
We know that tan(x) is defined as sin(x)/cos(x):
[tex]\tan \left(\frac{\pi }{2}\right),\\\sin \left(\frac{\pi }{2}\right)=1,\\\cos \left(\frac{\pi }{2}\right)=0,\\\\[/tex]
[tex]\tan \left(\frac{\pi }{2}\right) = 1/0 \\[/tex]
1/0 is undefined as 0 is in the denominator

•add -2y to both sides
3x+2y=21
-2y -2y
3x= -2y+2y
•then divide both sides by 3
3x/3 = -2y+21/3
•your answer:
x=-2/3y+7
x-4y=-7
•add 4y to both sides
x-4y=-7

A scout troop is planting trees at the state park. The troop planted 7 trees in 3 hours. At that rate, how many trees will they be able to plant in three 8-hour days?
Answers
Answer:
I believe 57
Step-by-step explanation:
7 trees per 3 hours
6 hours = 14 trees
plus the 2 hours which I'm assuming 5 to 4 trees
so you multiply 19 trees per day
19 x 3 = 57 if I'm wrong please correct me :)
This ellipse is centered at the origin. Find it’s equation. Verticles: (0,-6) (0,6) Foci: (0,-2) (0,2)
Answers
The equation of the ellipse will be x² / 36 – y² / 32 = 1.
What is an ellipse?An ellipse is a locus of a point that moves in a plane such that the sum of its distances from the two points called foci adds up to a constant. It is taken from the cone by cutting it at an angle.
This ellipse is centered at the origin.
Vertices: (0,-6) (0,6)
Foci: (0,-2) (0,2)
Then the equation of the ellipse will be given as
x² / a² – y² / b² = 1
Let c be the distance between the origin to foci.
Then we have
c = 2
And the value of a will be
a = 6
Then the value of a² will be
a² = 6² = 36
The value of b is the distance from center to one of the Co-vertices. Then the value of b² will be
a² – b² = c²
36 – b² = 2²
b² = 36 – 4
b² = 32
Then the equation of the ellipse will be x² / 36 – y² / 32 = 1.

Answers
Answer:
y = x + 1
Step-by-step explanation:
I HOPE IM NOT TOO LATE BUT basically first u use the points to find the slope:
[tex]\frac{3+1}{2+2} = \frac{4}{4} = 1[/tex]
so far then, u have y = x + b (there's an invisible 1 in front of the x)
next, substitute in the values from one set of coordinates to solve for b. I picked the second one bc positive numbers are easier:
y = x + b
3 = 2 + b
3 - 2 = b
1 = b
put this into your equation, and u get y = x + 1
hope this helps!
