5 0

Answer:

\frac{9}{4}

Step-by-step explanation:

We are given that

2 + (3+5 ) 2 ÷ 4 ( 1/2)^4

2 + (8 ) 2 ÷ 4 ( 1^4 / 2^4)

Applying rule of exponents which says

(a/b)^m = a^m / b^m

2 + (8 ) 2 ÷ 4 ( 1 / 16)

2 + (8) ( 1/ 2 )  (1 / 16)

2 + 4 ( 1/16)

2 + (1/4)

(8+1)/4

9/4

My name is Ann [436]

Answer:

98.3 seconds

Step-by-step explanation:

If you use stoichometry you can convert your units

9.83 seconds

over 100 meters    a kilometer is 1000 meters so

9.83/100 *10 because what you do to denominator needs to happen to numerator

98.3 seconds

over 1 kilometer

it take the sprinter 98.3 seconds to run a kilometer and one way to check is well a kilo is a longer distance so logically the time it takes them has to be higher cause they cannot run a kilo faster than they run 1/10 of it

What basic trigonometric identity would you use to verify that (sin2x + cos2x)/cosx=secx
Oksana_A [137]

Answer:

Step-by-step explanation:

sin(2x) = 2 sin(x) cos(x) cos(2x) = cos2(x) – sin2(x) = 1 – 2 sin2(x) = 2 cos2(x) – 1. Now I am not sure if this is right but I remember another similar formula. Here is the correct formula cot x = cos x / sin x

2 ) ( sin² x + cos² x ) / cos x = sec x

1/cos x = sec x

sec x = sec x

cos² x + sin² x = 1
