Substitute each given value of the variable to find which, if any, is a solution of inequality.

OlgaM077 [116]

Given:

The inequalities are:

a) $w$

b) $t>-25, t=-24, -25, -25.1, -27$

To find:

The solution of inequalities by substituting the given values.

Solution:

a) We have,

$w$

After substituting the given values one by one, we get

$-4.3$ False statement.

$-5.3$ False statement.

$-8.3$ True statement.

$-9$ True statement.

Therefore the solutions of $w$ are $w=-8.3, -9$ .

We have,

$t>-25, t=-24, -25, -25.1, -27$

After substituting the given values one by one, we get

$-24>-25$ True statement.

$-25>-25$ False statement.

$-25.1>-25$ False statement.

$-27>-25$ False statement.

Therefore, the solution of $t>-25$ is $t=-24$ .

Find a vector function, r(t), that represents the curve of intersection of the two surfaces. the paraboloid z = 9x2 y2 and the p

dolphi86 [110]

The vector function is, r(t) = $\bold{ < t,2t^2,9t^2+4t^4 > }$

Given two surfaces for which the vector function corresponding to the intersection of the two need to be found.

First surface is the paraboloid, $z=9x^2+y^2$

Second equation is of the parabolic cylinder, $y=2x^2$

Now to find the intersection of these surfaces, we change these equations into its parametrical representations.

Let x = t

Then, from the equation of parabolic cylinder, $y=2t^2$ .

Now substituting x and y into the equation of the paraboloid, we get,

$z=9t^2+(2t^2)^2 = 9t^2+4t^4$

Now the vector function, r(t) = <x, y, z>

So r(t) = $\bold{ < t,2t^2,9t^2+4t^4 > }$

What is the center and radius of the circle with equation (x - 2)^2 + (y - 5)^2 = 100?

ololo11 [35]

Answer:
Center = (2,5)
Radius = 10
Choice A

To find this answer, first write the equation
(x-2)^2 + (y-5)^2 = 100
into
(x-2)^2 + (y-5)^2 = 10^2

Note how the second equation is in the form
(x-h)^2 + (y-k)^2 = r^2

We see that (h,k) = (2,5) is the center
and r = 10 is the radius

14 less than a number all divided by the same number

Fynjy0 [20]

Answer:

(n-14) / n

Step-by-step explanation:

n is your number;

"14 less" means "subtract 14", --> we have (n-14);

now we need to divide (n-14) by same number as your number, which is "n"---> final expression is: (n-14)/n
