Please i want to know how to find slope intercepts

algol [13]

Answer:

Identify the slope, m. This can be done by calculating the slope between two known points of the line using the slope formula.

Find the y-intercept. This can be done by substituting the slope and the coordinates of a point (x, y) on the line in the slope-intercept formula and then solve for b.

Step-by-step explanation:

The general formula is y = mx +b.

m = slope.

b = y-intercept of the line

Determine the center and radius: x2 + y2 - 10x + 8y -8 = 0

Kipish [7]

So our equation currently is ⇒ $x^2+y^2-10x+8y-8 = 0$

Let's first move all the constant to one side and group 'like variables' together:

$(x^2-10x)+(y^2+8y) = 8$

Now lets complete the square of both equations

$(x^2-10x+25)+(y^2+8y +16) = 8 + 25 + 16\\(x-5)^2+(y+4)^2 = 49\\(x-5)^2+(y+4)^2 = 7^2$

Now we know the circle's general equation format is:

⇒ $(x-h)^2+(y-k)^2 = r^2$

(h, k) ⇒ coordinate of the center of the circle
r ⇒ length of radius of circle

Thus the radius of the circle is 7

Hope that helps!

A light bulb has a lifetime X that is exponentially distributed with a mean 340 hours. Find the probability that the bulb lifeti

LUCKY_DIMON [66]

Answer:

0.7026

Step-by-step explanation:

Let X denote the lifetime of light bulb. Given $X \sim Exp(\lambda)$ where the mean is $E(X) = 340 =\frac{1}{\lambda} \implies \lambda = \frac{1}{340} = 0.00294$ .

Recall that,

$\displaystyle P(X>x) = 1 - \int_0^x e^{-\lambda x} = 1 - (1 - e^{-\lambda x} = e^{-\lambda x}$

$\displaystyle P(X>220 | X>100) = \frac{P(X>220,X>100)}{P(X>100)} = \frac{e^{-\lambda \times 220}}{e^{-\lambda \times 100}} = \frac{0.5236}{0.7452} = 0.7026$
