Which is the equation of an ellipse centered at the origin with foci on x-axis, x-intercepts +7, -7 and y-intercepts +2,
Aleks04 [339]
We know that
<span>foci on x-axis-------> is a ellipse with horizontal major axis

the equation is
(x</span>²/a²)+(y²/b²)=1

major axis is th<span>e </span>x<span>-axis with length </span><span>2<span>a
2a=14--------> a=7

</span></span>minor axis is the y<span>-axis with length </span><span>2<span>b
2b=4-----> b=2

the equation is
</span></span>(x²/a²)+(y²/b²)=1------> (x²/7²)+(y²/2²)=1-----> (x²/49)+(y²/4)=1

the answer is
(x²/49)+(y²/4)=1

see the attached figure

If tan x=.67, and cos x=.83, what is sin x
Alexxandr [17]

Answer:

0.56

Step-by-step explanation:

                                  sin x

tan x is defined as -------------

                                  cos x

and we can solve this for sin x:  sin x = (cos x)(tan x)

which here is:  sin x = 0.83(0.67) = 0.56 (rounded up from 0.5561)
