Answer:
x = 0, 2, -2
Step-by-step explanation:
3x^3 - 12x = 0
3x ( x^2 - 4 ) = 0
3x = 0
x = 0
x^2 - 4 = 0
( x -2 ) ( x + 2 ) = 0
x -2 = 0
x = 2 , x + 2 = 0
x = -2

NO LINKS!!! Solve each triangle. Part 3aa
NOT A MULTIPLE CHOICE!!
1aa. B=10°, C=100°, b= 2
2bb. A= 40°, B= 40°, c= 2
3cc. A= 110°, C= 30°, c= 3
Answer:
Sum of interior angles of a triangle = 180°
Sine rule to find side lengths:
[tex]\dfrac{a}{\sin A}=\dfrac{b}{\sin B}=\dfrac{c}{\sin C}[/tex]
----------------------------------------------------------------------
Question 1aa
Given: B = 10°, C = 100°, b = 2
10° + 100° + A = 180°
⇒ A = 70°
[tex]\dfrac{a}{\sin 70}=\dfrac{2}{\sin 10}=\dfrac{c}{\sin 100}[/tex]
[tex]\implies a=\sin 70 \cdot \dfrac{2}{\sin 10}=10.82294826...[/tex]
[tex]\implies c=\sin 100\cdot \dfrac{2}{\sin 10}=11.34256364...[/tex]
----------------------------------------------------------------------
Question 2bb
Given: A = 40°, B = 40°, c = 2
40° + 40° + C = 180°
⇒ C = 100°
[tex]\dfrac{a}{\sin 40}=\dfrac{b}{\sin 40}=\dfrac{2}{\sin 100}[/tex]
[tex]\implies a=\sin 40\cdot\dfrac{2}{\sin 100}=1.305407289...[/tex]
[tex]\implies b=\sin 40\cdot\dfrac{2}{\sin 100}=1.305407289...[/tex]
----------------------------------------------------------------------
Question 1aa
Given: A = 110°, C = 30°, c = 2
110° + 30° + B = 180°
⇒ B = 40°
[tex]\dfrac{a}{\sin 110}=\dfrac{b}{\sin 40}=\dfrac{3}{\sin 30}[/tex]
[tex]\implies a=\sin 110 \cdot \dfrac{3}{\sin 30}=5.638155725...[/tex]
[tex]\implies b=\sin 40\cdot\dfrac{3}{\sin 30}=3.856725658...[/tex]

Consider a Poisson distribution with a mean of two occurrences per time period. a. Which of the following is the appropriate Poisson probability function for one time period? 1 2 3 - Select your answer - b. What is the expected number of occurrences in three time periods? c. Select the appropriate Poisson probability function to determine the probability of occurrences in three time periods. 1 2 3 - Select your answer - d. Compute the probability of two occurrences in one time period (to 4 decimals). e. Compute the probability of six occurrences in three time periods (to 4 decimals). f. Compute the probability of five occurrences in two time periods (to 4 decimals)
Answer:
F(k) = 2k e-2 / k!
Mean =µ = 2 x 3 = 6
f(k) = 6k e-6 / k!
F(2) = 22 e-2 / 2!
= 0.2707
F(6) = 66 e-6 / 6!
= 0.1606
f(5) = 45 e-4 / 5!
= 0.1563
Step-by-step explanation:
Solution:
Given:
Mean = µ = 2 per time period
Poisson probability:
F(k) = µk e-µ / k!
(a) Poisson probability for one time period.
Put µ = 2 in formula, we get:
F(k) = 2k e-2 / k!
(b) Expected number of occurrence in three time period.
Mean of one time period is multiply with number of time period.
Mean =µ = 2 x 3 = 6
(c) Probability of occurrence in three time period.
Put the value of µ = 6 in the given formula, we get:
f(k) = 6k e-6 / k!
(d) Probability of two occurrences in one time period.
Put k = 2 in given formula:
F(2) = 22 e-2 / 2!
= 0.2707
(e) Probability of six occurrences in three time period.
Put k = 6, in given formula, we get:
F(6) = 66 e-6 / 6!
= 0.1606
(f) Probability of five occurrences in two time period.
Mean of one time period is multiply by the number of time periods.
µ = 2 x 2 = 4
put k = 5 and µ = 4 in formula, we get:
f(5) = 45 e-4 / 5!
= 0.1563
Whole numbers that go one after another are called consecutive numbers. If you add 4 consecutive numbers, you get the smallest of these numbers multiplied by 5. What is this smallest number?
Answer:
The smallest number be 6.
Step-by-step explanation:
Let the 4 consecutive numbers be :
n,n+1,n+2,n+3 where n is the smallest number
Adding up the 4 consecutive numbers, we get :
n+n+1+n+2+n+3 = 4n+6
ATQ,
4n+6 = 5n
Taking like terms together,
6=5n-4n
⇒ n = 6
So, the smallest number be 6.
find the rate of change from the equation y=-7/8x+3
Answer:
-7/8
Step-by-step explanation:
rate of change is the same as slope so -7/8
Answer:
-7/8Step-by-step explanation:
find the rate of change from the equation:
y = -7/8x + 3
use the formula: y = mx + b
where:
y = how far up the line goes
m = slope
x = how far along
b = Y-intercept
so the rate of change is the same as the slope
therefore, the slope = -7/8

Lily invested $60,000 in an account paying an interest rate of 6 1 2 6 2 1 % compounded continuously. Lydia invested $60,000 in an account paying an interest rate of 6 1 8 6 8 1 % compounded monthly. To the nearest hundredth of a year, how much longer would it take for Lydia's money to triple than for Lily's money to triple?
Using interest equations, it is found that it will take 1.08 year more for Lydia's money to triple than for Lily's.
What is compound interest?The amount of money earned, in compound interest, after t years, is given by:
[tex]A(t) = P\left(1 + \frac{r}{n}\right)^{nt}[/tex]
In which:
A(t) is the amount of money after t years. P is the principal(the initial sum of money). r is the interest rate(as a decimal value). n is the number of times that interest is compounded per year. t is the time in years for which the money is invested or borrowed.What is the amount in continuous compounding?It is given by:
[tex]A(t) = Pe^{rt}[/tex]
For Lily, the parameters are as follows: r = 0.065, with continuous compounding. The time to triple is t for which A(t) = 3P, hence:
[tex]A(t) = Pe^{rt}[/tex]
[tex]3P = Pe^{0.065t}[/tex]
[tex]e^{0.065t} = 3[/tex]
[tex]\ln{e^{0.065t}} = \ln{3}[/tex]
[tex]0.065t = \ln{3}[/tex]
[tex]t = \frac{\ln{3}}{0.065}[/tex]
[tex]t = 16.90[/tex].
For Lydia, using compound interest, the parameters are: r = 0.06125, n = 12, hence:
[tex]A(t) = P\left(1 + \frac{r}{n}\right)^{nt}[/tex]
[tex]3P = P\left(1 + \frac{0.06125}{12}\right)^{12t}[/tex]
[tex](1.00510416667)^{12t} = 3[/tex]
[tex]\log{(1.00510416667)^{12t}} = \log{3}[/tex]
[tex]12t\log{(1.00510416667)} = \log{3}[/tex]
[tex]t = \frac{\log{3}}{12\log{(1.00510416667)}}[/tex]
[tex]t = 17.98[/tex]
17.98 - 16.9 = 1.08, hence, it will take 1.08 year more for Lydia's money to triple than for Lily's.

what is the answer to 15x+6y
Answer:
x = -0.4y
Step-by-step explanation:
Simplifying
15x + 6y = 0
Solving
15x + 6y = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-6y' to each side of the equation.
15x + 6y + -6y = 0 + -6y
Combine like terms: 6y + -6y = 0
15x + 0 = 0 + -6y
15x = 0 + -6y
Remove the zero:
15x = -6y
Divide each side by '15'.
x = -0.4y
