The answer would be c because 1-5-7 is the same as 5-8
The solution to the quadratic equation given by:
6x^2+2x-20=0
will be:
6x^2+2x-20=0
factoring the above we get:
6x^2+12x-10x-20=0
6x(x+2)-10(x+2)=0
(6x-10)(x+2)=0
hence:
6x=10
x=10/6=5/3
or
x+2=0
x=-2
Thus the answer is:
x=5/3
x=-2
Trigonometry.
We must use the SOH CAH TOA rule to find the missing angle, x.
Given that the two known sides: opposite to angle x is 7 and the adjacent side to angle x is 11, we use the tan sign because tan is for TOA which is (opposite/adjacent).
So we can write the equation like this:
tan(x)= 7/11
To get x, inverse tan on calculator:
Tan^-1 (7/11) = 32.4711...
Round it off = 32 degrees.
Graph y=cos(x)+3. y=cos(x)+3. Use the form acos(bx−c)+d a c o s ( b x - c ) + d to find the variables used to find the amplitude, period, phase shift, and vertical shift. a=1.
