SOLVE THIS VERY IMPORTANT QUESTION​

Mathematics
1 answer:
tester [92]2 years ago
3 0

Answer:

Step-by-step explanation:

\dfrac{Cos \ A}{1 + Sin \ A}=\dfrac{Cos \ A *(1-Sin \ A)}{(1+Sin \ A)(1 - Sin \ A)}\\\\\\=\dfrac{Cos \ A *(1 - Sin \ A)}{1^{2}-Sin^{2} \ A}\\\\\\=\dfrac{Cos \ A *(1 - Sin \ A)}{Cos^{2} \ A}\\\\\\=\dfrac{1-Sin \ A}{Cos \ A}------(I)

LHS =\dfrac{Cos \ A}{1+Sin \ A}+\dfrac{1+Sin \ A}{Cos \ A}\\\\\\ = \dfrac{1-Sin \A}{Cos \ A}+\dfrac{1+Sin \ A}{Cos \ A} \ [from \ equation \ (I)]\\\\\\=\dfrac{1-Sin \ A + 1 - Sin \ A}{Cos \ A}\\\\=\dfrac{2}{Cos \ A}\\\\\\=2*Sec \ A = RHS

Please can someone help my assignment​
Vadim26 [7]

Answer:

Find answers below

Step-by-step explanation:

First know that any value raise to power zero is 1 and also according to the inverse law;

a⁻ⁿ = 1/aⁿ

Given the following

a) (-123)⁰ = 1 ()Note that any value raise to zero is 1

b) 43⁻⁵ = 1/43⁵

1/43⁵ = 1/147,008,443

c) 1/15⁻⁶ = 1/(1/15⁶)

1/(1/15⁶) = 1*15⁶/1

1/(1/15⁶) = 15⁶

d) -(1353348)⁰

= -1 (anything raise to zero is 1)

e) 13⁻⁴ = 1/13⁴

= 1/28,561

It takes an airplane 5/12 of a minute to fly 3/4 of a mile. What is the airplanes speed per minute?
Nikitich [7]
To make this a little easier, you would want to turn 3/4 into 9/12, to match 5/12's denominator.

You would then just add 7/1 to both fractions

(5/12+7/1=12/12 or 1 minutes)
(9/12+7/1=16/12=1 1/3)

So your answer would be 1.333... miles per minute

Hope this helps
