D^2y/dx^2+4dy/dx-12y=cos2x

1 answer:

3 0

If you're solving for x, you'd move all the terms containing x to the left side of the equation:

d^2y/dx^2+4y/x-12y-cos^2(x)+sin^2(x)=0

If you're solving for y, you'd simplify both sides of the equation, then isolating the variable:

y=xcos(2x)

0=x^2- 10x+10<br> Rewrite the equation by completing the square

zubka84 [21]

$~~~~~~x^2 -10x +10 =0\\\\\implies x^2 -2 \cdot 5 \cdot x +5^2 -5^2 +10 = 0\\\\\implies (x-5)^2 -25+10 = 0\\\\\implies (x-5)^2 -15=0\\\\\implies (x-5)^2 = 15$

Solve quadratic equation (x-3)^2+5=14

loris [4]

(X-3)^2+5=14
Step 1: simplify both sides of the equation
X^2-6x+14=14

Step 2: subtract 14 from both sides
X^2-6x+14-14=14-14
X^2-6x=0

For this equation: a=1, b=-6,c=0
1x^2+-6x+0=0

Step 3: Use quadratic formula with a=1, b=-6, c=0

The answer is x=6 or x=0

A bicycle wheel with the diameter 70cm is making 25 revolutions while travelling. Find the distance covered by the bicycle

Diano4ka-milaya [45]

Answer: 5500cm.

Step-by-step explanation:

A revolution corresponds to circumference of the bicycle wheel.

The radius of the circle = 70/2 since two radii makes a diameter.

Therefore r = 35cm

Circumference of a circle = 2πr or πd where π = 3.142 or 22/7

We now have = 2 x 22/7 x 35

Therefore 0ne revolution = 220cm.

Therefore, the distance traveled by making 25 revolution

= 220 x 25

= 22000/4

= 5500cm.

Pls check screenshot 50 points

arsen [322]

Answer:

See below

Step-by-step explanation:

f(x - 1) is the translation of f(x) one unit right.

So the graph is exactly same shape but shifted right one unit.

f(x) has vertex (-1, 2)

<u>The function y = f(-x) + 2 will have the vertex changed as per rule:</u>

(x, y) → (-x, y + 2)

<u>So the new vertex is:</u>

(-1, 2) → (-(-1), 2 + 2) = (1, 4)
