Answer:

The answer is CB.

Step-by-step explanation:

A ray is a line that starts from a point and travels in a particular direction to infinity.

Here, CB is the ray as it is originating from a point C and travelling up to infinity in a single direction beyond B.

The ray is represented by a arrow in one direction.

1420-1065 = 355 dollars. Lets find out how many percent 355 dollars are of the original prise. We divide them 355/1420= 0,25, we then say 0,25 * 100 = 25%

Solve the quadratic equation<br> give your answer to 2 decimal places<br> : 3x^2+x-5=0

Dima020 [189]

Given:

The quadratic equation is:

$3x^2+x-5=0$

To find:

The solution for the given equation rounded to 2 decimal places.

Solution:

Quadratic formula: If a quadratic equation is $ax^2+bx+c=0$ , then:

$x=\dfrac{-b\pm \sqrt{b^2-4ac}}{2a}$

We have,

$3x^2+x-5=0$

Here, $a=3,b=1,c=-5$ . Using the quadratic formula, we get

$x=\dfrac{-1\pm \sqrt{1^2-4(3)(-5)}}{2(3)}$

$x=\dfrac{-1\pm \sqrt{1+60}}{6}$

$x=\dfrac{-1\pm \sqrt{61}}{6}$

$x=\dfrac{-1\pm 7.81025}{6}$

Now,

$x=\dfrac{-1+7.81025}{6}$

$x=1.13504167$

$x\approx 1.14$

And

$x=\dfrac{-1-7.81025}{6}$

$x=-1.468375$

$x\approx -1.47$

Therefore, the required solutions are 1.14 and -1.47.

Find all values of m so that the function y= e^mx is a solution of the given differential equation.

son4ous [18]

Answer:

m = - 2 is the value of m that the function y= e^mx is a solution of the differential equation, y' + 2y = 0.

Step-by-step explanation:

To determine all values of m so that the function y= e^mx is a solution of the given differential equation.

First, we will find y'.

From, y= e^mx

$y = e^{mx}$

But, $y' = \frac{d}{dx}y$

Hence,

$y' = \frac{d}{dx}e^{mx}\\$

∴ $y' = me^{mx}$

Now, we will put the values of y' and y into the given differential equation y' + 2y =0

From the question,

$y = e^{mx}$

and

$y' = me^{mx}$

Then, $y' + 2y =0\\$ becomes

$me^{mx} + 2(e^{mx}) = 0$

Then, $me^{mx} = - 2(e^{mx}) \\\\$

$m = \frac{-2(e^{mx}) }{e^{mx} } \\$

∴ $m = -2$

Hence, m = - 2 is the value of m that the function y= e^mx is a solution of the differential equation, y' + 2y = 0.

Which segment is the altitudes of the pyramid?

NikAS [45]

Altitude of a pyramid is the perpendicular distance from the vertex to the plane of the base. Base can be regular or irregular in pyramid. In regular pyramid, altitude and the slant height of a pyramid are not the same as the slant height is the length of the face of the pyramid. Altitude meets the base at its center.
