Answer:

Cos A = 24/25, Tan A = 7/25

Step-by-step explanation:

Given that Sin A = 7/25

Sin = Opp/hyp

Therefore using Pythagoras theorem, adjacent will be;

= √(25²-7²)

= √576

= 24

Thus;

Cos A = adjacent/hypotenuse

          =  24/25

Cos A = 24/25

Tan A = opp/hypotenuse

         = 7/25

Tan A = 7/25

Answer:

The correct answer is option A

Cos A = 24/25 and Tan A = 7/24

Step-by-step explanation:

<u>Trigonometric ratio</u>

Sinθ = Opposite side/Hypotenuse

Cos θ = Adjacent side/Hypotenuse

Tan θ = Opposite side/Adjacent side

From the figure we get,

Sin A = 7/24

Opposite side = 7 and Hypotenuse = 25

<u>To find the adjacent side of A</u>

Adjacent side² = Hypotenuse² - Adjacent side ² = 25² - 7² = 625 - 49 = 576

Adjacent side = √576 = 24

<u>To find the CosA and TanA </u>

CosA = Adjacent side/Hypotenuse  = 7/25

TanA = Opposite side/Adjacent side = 24/25

Answer:

b=\pm2\sqrt{2}

Step-by-step explanation:

For the spring mass system

my"+by'+ky=0

The system is said to be critically damped if b^2-4mk=0

Here b is coefficient of friction

m is the mass of system

And k is spring constant

We have given m = 2 kg , k =1

So b^2-4\times 2\times 1=0

b^2=8

b=\pm2\sqrt{2}

So the coefficient of friction is \pm2\sqrt{2}

betty has a cow.the cow produces 5 liters of milk in a day. if the cows diet is improved the cow will produce 200% more milk.how
DanielleElmas [232]
We can start by setting out what we know simply.

Cow produces 5 liters a day.

The cow can make 200% more.

200% of 5, is 10. 

If he makes 200% more, he will make 10 liters more.

He already makes 5.

10+5 is what he will make.

FINAL ANSWER:

<em>"If the cow's diet is improved, the cow will produce 15 liters of milk in a day."</em>
