Divide 5600 in the ratio 4 :5:7 ​

Mathematics
1 answer:
Elis [28]2 years ago
5 0

Answer:

Step-by-step explanation:

So in our case, let assume 'x' as a common factor.

Thus,

4x + 5x + 7x = 5600;

16x = 5600;

x = 5600/16 = 350.

So,

4x= 350*4 =1400;

5x= 350*5 = 1750; &

7x= 350*7 = 2450.

Your answer is, 5600 = 1400+1750+2450 which is in ratio of 4:5:7.

Find all the zeros of the function f(x) = x^3 -2x^2 +16x -32
Alex777 [14]

Answer:

<h2>Real zeros: x = 2</h2><h2>All zeros: x = 2, x = -4i and x = 4i</h2>

Step-by-step explanation:

f(x)=x^3-2x^2+16x-32\\\\\text{The zeros:}\\\\f(x)=0\Rightarrow x^3-2x^2+16x-32=0\\\\x^2(x-2)+16(x-2)=0\\\\(x-2)(x^2+16)=0\iff x-2=0\ \vee\ x^2+16=0\\\\x-2=0\qquad\text{add 2 to both sides}\\\boxed{x=2}\\\\x^2+16=0\qquad\text{subtract 16 from both sides}\\x^2=-16

Given sin (-theta) = 1/5 and tan theta = sqrt.6/12
stich3 [128]

Given  sin (\theta) = \frac{1}{5}, andtan \theta = \frac{\sqrt{6} }{12}, then:

cos\theta=\frac{2\sqrt{6} }{5}

<h3> Computations on trigonometric identities</h3>

From the details provided:

sin (\theta) = \frac{1}{5}\ \\\\tan \theta = \frac{\sqrt{6} }{12} \times \frac{\sqrt{6} }{\sqrt{6} }\\\\tan \theta = \frac{\sqrt{6} \times \sqrt{6} }{12 \times \sqrt{6} }\\\\tan \theta =\frac{1}{2\sqrt{6} }

From the relationship above:

Opposite = 1

Adjacent = 2\sqrt{6}

Hypotenuse = 5

cos\theta=\frac{Adjacent}{Hypotenuse} \\\\cos\theta=\frac{2\sqrt{6} }{5}
