1/sin^2x-1/tan^2x=
1/sin^2x-1/ (sin^2x/cos^2x)<<sin tan= sin/cos>>
= 1/sin^2x- cos^2x / sin^2x
= (1- cos^2x) / sin^2x <<combining into a single fraction>>
sin^2 x / sin^2x <<since 1- cos^2 x sin^2 x
=1
this simplifies to 1.
Answer:
x = 6
y = -2
Step-by-step explanation:
6 - 8 = -2
2 x 6 = 12 - 14 = -2
<span>1st number = 11, 2nd number = 5.5, 3rd number = -5.5</span>
Answer:
Step-by-step explanation:
This is a unit rate problem. If we want to find out how much chocolate was eaten in 1 minute, we divide 31.5 by 7. This gives us the number of ounces of chocolate eaten in 1 minute: 4.5 ounces per minute.
1m is approximately 3 feet whereas 1m is approximately 3280 feet. Therefore, the best estimate for the heiht of a desk would be 1 m
