So you have some initial amount x and we want to know how long it will take with compound interest to triple our original amount x (so 3x). The equation sets up like 3x(the amount we want)= x(original amount) times 1.062(the interest increase)^t So 3x=x(1.062)^t where t is the amount of years. When you divide both sides by x it cancels out and you end up with 3=1.062^t. Take the natural log of both sides. Ln(3) = Ln(1.062^t) and the t being an exponent can come in front of the the natural log. Ln(3) = t(Ln(1.062)) Divide both sides by (Ln(1.062)),. Ln(3)/Ln(1.062)=t. And you should just plug that into a calculator to find t.
Answer:
x = 1 and y = - 4
Step-by-step explanation:
The equation of a vertical line is
x = c
where c is the value of the x- coordinates the line goes through.
Here the line passes through (1, - 4) with x- coordinate 1, thus
x = 1 ← equation of vertical line
The equation of a horizontal line is
y = c
where c is the value of the y- coordinates the line goes through.
Here the line passes through (1, - 4) with y- coordinate - 4, thus
y = - 4 ← equation of horizontal line
According to the null hypothesis, the test statistic of the proportion is of z = 120.1.
<h3>
What is the null hypothesis?</h3>
The claim is that the rate of nausea is greater than the 6% rate experienced by flu patients given a placebo. At the null hypothesis, we consider the claim as false, hence the null hypothesis is:

<h3>What is the test statistic?</h3>
The test statistic is given by:

In which:
is the sample proportion.
- p is the proportion tested at the null hypothesis.
In this problem, the parameters are:

Hence, the test statistic is given by:

Answer:
The value is 
Step-by-step explanation:
From the question we are told that
The velocity of the wind southward is 
The resultant velocity of the bird with the with wind is
Generally for an object moving in the northwest direction the angle with the horizontal is 45°
Generally the velocity of the bird in the along the x -axis is

Generally the velocity of the bird in the along the y -axis is

Here
is the velocity of the bird without the wind
Generally the resultant velocity of the bird with the with wind is mathematically represented as

=> 
Generally

and

So
![\sqrt{53} = \sqrt{(v_b* (\frac{1}{\sqrt{2} ))^2 + ([v_b * (\frac{1}{\sqrt{2} ) ]- 5)^2 }](https://tex.z-dn.net/?f=%20%20%5Csqrt%7B53%7D%20%20%3D%20%20%5Csqrt%7B%28v_b%2A%20%28%5Cfrac%7B1%7D%7B%5Csqrt%7B2%7D%20%29%29%5E2%20%2B%20%28%5Bv_b%20%2A%20%28%5Cfrac%7B1%7D%7B%5Csqrt%7B2%7D%20%29%20%5D-%205%29%5E2%20%7D)
=> 
=>
=>
Solving the above quadratic equation using quadratic formula we obtain that

The other value is negative so we do not make use of it because we know that the bird is moving in the positive x and y axis
