If (m, 2) is on a circle with center (−3, 2) and radius 8, what is a value of m?

Talja [164]

$\bf \textit{distance between 2 points}\\ \quad \\
\begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
% (a,b)
&({{ -3}}\quad ,&{{ 2}})\quad 
% (c,d)
&({{ m}}\quad ,&{{ 2}})
\end{array}\qquad 
% distance value
d = \sqrt{({{ x_2}}-{{ x_1}})^2 + ({{ y_2}}-{{ y_1}})^2}$

$\bf \textit{we know the distance from m,2 and -3,2(center) is the radius}
\\\\\\
d=8\implies 8=\sqrt{[m-(-3)]^2+[2-2]^2}
\\\\\\
8=\sqrt{(m+3)^2+(0)^2}\implies 8=\sqrt{(m+3)^2}\implies 8^2=(m+3)^2
\\\\\\
64=(m+3)^2\implies \sqrt{64}=\sqrt{(m+3)^2}\implies 8=m+3
\\\\\\
8-3=m$

Customer arrivals at a bank are random and independent; the probability of an arrival in any one-minute period is the same as th

deff fn [24]

Answer:

a)0.2240

b)0.5768

Step-by-step explanation:

Given:

µ=3

Poison probability is given by :

$f_k=\frac{\mu^ke^-^\mu}{k!}$

a) Evaluating at k=3

$f(3)=\frac{3^3e^-^3}{3!} \approx 0.2240$

b)Evaluating at k=0,1,2:

$f(0)=\frac{3^0e^-^3}{0!} \approx 0.0498$

$f(1)=\frac{3^1e^-^3}{1!} \approx 0.1494$

$f(2)=\frac{3^2e^-^3}{2!} \approx 0.2240$

Use complement rule:

P(x≥3)= 1 - f(0) - f(1) - f(2)= 1- 0.0498 - 0.1494 - 0.2240 =0.5768

A spring is hanging from a ceiling. The length L(t) (in cm) of the spring as a function of time t (in seconds) can be modeled by

Zanzabum

Answer:

L(t) = 5·sin(πt) +7

Step-by-step explanation:

The middle of the oscillation of the given function occurs when t=0. At that point, ...

L(0) = d = 7

The next maximum of the oscillation occurs when the argument of the sine function is π/2.

b·t = π/2

b = π/(2t) = π/(2·0.5) = π

At that maximum, the length is 12, so we have ...

L(0.5) = a·sin(0.5π) +7 = 12

a = 5

The function L(t) is ...

L(t) = 5·sin(πt) +7
