Let the number be a ...
i.e ,70% of a =126 ..
=> 70/100 X a =126
=>7/10 a =126
=>7 a = 126 X 10
=>7 a= 1260
=>a = 1260/7
a = 180 ..
Hope it helps !!!
Answer:
B. Cosecant is the reciprocal of sine
Step-by-step explanation:
Well, this is where you have to remember your reciprocal identities in your trigonometric identities!
So:
- Cosecant is the reciprocal of sine
- Secant is the reciprocal of cosine
- Cotangent is the reciprocal of tangent
How I remember them is just the co is with the non-co (cosecant with sine (no co there) and cosine with secant. Tangent with cotangent is pretty easy to remember.)
I'll attach a picture for trig identities! Let me know if you have any further questions :)
Answer:
10.
Step-by-step explanation:
x^2 + 5x = 150
x^2 + 5x - 150 = 0
This equation will factor:
(x - 10)(x + 15) = 0
x - 10 = 0 or x + 15 = 0, so:
x = 10 or -15.
Yes. 5 meters = 500 centimeters.
