Sine, Cosine and Tangent. And Sine, Cosine and Tangent are the three main functions in trigonometry. They are often shortened to sin, cos and tan. The calculation is simply one side of a right angled triangle divided by another side ... we just have to know which sides, and that is where "sohcahtoa" helps. :)
2(3x5) + 2(3x9) + 2(5x9) = 174 in2
I believe this is correct answer
Answer:
2a) $1,500 markup
2b) $9000
Step-by-step explanation:
20% of 7500 is 1500
7500 + 1500 = 9000
Hope this helps!
The required vertex form of the given equation is a) is correct
the function is given,
<h3>What is vertex form?</h3>
vertex form of a equation is given by .
since
Now h = - b/2a
h = -N
Now at x = 0
k = 10
vector form can be given by
The question is incomplete. The question could be:

To solve for any given number of variables, you need that number of equations to solve for all variables. When there are only two variables you only need to equations to solve for them both. You eliminate one variable at a time, order does not matter.
y-x=6 and y+x=-10
Since one equation has -x and the other +x, you can simply add the two equations together to eliminate x...
(y-x=6)+(y+x=-10)
y+y-x+x=6-10
2y=-4
y=-2, now you can use this value of y in either original equation to solve for x...
y-x=6, using y=-2 becomes:
-2-x=6
-x=8
x=-8
So the solution to the system of equations is the point (-8, -2)
You can always check by using these two values in the original equations...
y-x=6, -2--8=6, -2+8=6, 6=6
y+x=-10, -2+(-8)=-10, -2-8=-10, -10=-10
