PLEASE SOLVE I DESPERATELY NEED HELP!!! Solve the system of equations by graphing.
Anon25 [30]

Answer:

The steps will be :

1. Draw both equations into the graph.

2. Look for the coordinates where they intersect(curve and line crosses each other). So the coordinates will be (-2,0) and (3,5).

3. The x-value of the coordinates will the solution to the equations.

4. Therefore, the answer will be -2 and 3.

Would appreciate some help with this:<br><br> Verify (sinq+cosq)^2 - 1 = sin2q
Phantasy [73]

Hello from MrBillDoesMath!

Answer:

See Discussion below

Discussion:

(sinq + cosq)^2 =                                     => (a +b)^2 = a^2 + 2ab + b^2

(sinq)^2 + (cosq)^2 + 2 sinq* cosq        => as (sinx)^2 + (cosx)^2 = 1

1 + 2 sinq*cosq              (*)


Setting a = b = q in the trig identity:

sin(a+b) = sina*cosb + cosa*sinb                      

sin(2q) =                      (**)

sinq*cosq + cosq*sinq      => as both terms are identical

2 sinq*cosq


Combining (*) and (**)

(sinq + cosq)^2 = 1 + 2sinq*cosq     => (**) 2sinq*cosq =  sqin(2q)

                          = 1 +  sin(2q)

Hence

(sinq + cosq)^2  = 1 +  sin(2q)            => subtracting 1 from both sides

(sinq + cosq)^2  - 1 =   sin(2q)  

The last statement is what we are trying to prove.



Thank you,

MrB

Point A (-7,-2) is rotated 270 counterclockwise and then shifted down 3 units. What are to coordinates of K’
AfilCa [17]

Answer:

K'= (-2, 4)

Step-by-step explanation:

First we are going to rotate our point 270° counterclockwise.

The rule for a 270° counterclockwise rotation is (x,y)-->(y,-x), which means that we just need to interchange the coordinates of the point and change the sign of the x-coordinate:

(x,y)-->(y,-x)

(-7,-2)-->(-2,-7)

(-7,-2)-->(-2,-(-7))

(-7,-2)-->(-2,7)

Now, to shift the point 3 units down, we just need to subtract 3 units from the new y-coordinate of our resulting point form the previous procedure:

(x,y)-->(x,y-3)

(-2,7)-->(-2,7-3)

(-2,7)-->(-2,4)

We can conclude that the coordinates of K' are (-2, 4)

This uses pythagorean theorem
Klio2033 [76]

Step-by-step explanation:

x²=a²+b²

x=√6²+12²

x=√180

x=3√2v

y²=16²+12²

y=√400

y=20
