Miguel plans on retiring in 16 years, and he wants to double his money by that time. He's contacted various banks, looking for a CD that compounds interest monthly, and to calculate what annual interest rate he needs, he is using the rule of 72. (3 points: Part I – 1 point; Part II – 1 point; Part III – 1 point)

Part I: What is the rule of 72? To represent the annual interest rate, use r.








Part II: What equation can Miguel set up to solve for the annual interest rate he needs to double his money by the time he retires?








Part III: What annual interest rate does Miguel need to double his money by the time he retires?

Answer:

99.93 [tex]m^{2}[/tex]

Step-by-step explanation:

1.  The area of a circle is defined by the equation: A = [tex]\pi r^{2}[/tex]

2. We can plug in the radius and solve the equation: A = [tex]\pi *5.64^{2}[/tex]

3. A = π * 31.8096

4. A = 99.932

5. A = 99.93

The equation of the parabola is y - 1 = (2/3) * (x - 3)².

The general equation of a parabola is: y-k = a(x-h)²

(h, k) - Coordinates of the vertex.

a - Vertex constant

Here:

(h, k) = (3, 1) and (x, y) = (0, 7).

So,

7 - 1 = C · (0 - 3)²

Step-by-step explanation: It really depends on the college.

Directed numbers are numbers that have either a positive or negative sign, which can be shown on a number line. Therefore, point F is Fifteen-halves of line segment DE.

A number line is a system that can show the positions of positive or negative numbers. It has its ends ranging from negative infinity to positive infinity. Thus any directed number can be located on the line.

Directed numbers are numbers with either a negative or positive sign, which shows their direction with respect to the number line.

In the given question, the distance between points D and E is 9 units. So that dividing 9 units in the ratio of 5 to 6, we have;

[tex]\frac{5}{6}[/tex] x 9   = [tex]\frac{45}{6}[/tex]

          = [tex]\frac{15}{2}[/tex]

Therefore, the location of point F, which partitions the directed line segment from d to E into a 5:6 ratio is    [tex]\frac{15}{2}[/tex]. Thus the answer is Fifteen-halves.

Answer:

There could be 0, 2, or 4 complex solutions

Step-by-step explanation:

The Fundamental Theorem of Algebra states that any polynomial with n degree will have n solutions So since the degree of the polynomial you provided has a degree of 4, that means there are 4 possible solutions. This question specifically asks for complex zeroes. Complex zeroes come in conjugate pairs, so that means if you have one complex zero, there is another complex zero which is it's conjugate. For this reason, there can only be an even number of complex zeroes. And since there's 4 possible solutions, There could be 0, 2, or 4 complex solutions

Answer:

(i) -34° C.
(ii) The temperature had fallen by 11° C.

Step-by-step explanation:

(i) As it's a negative number its like we are adding it so 23 + 11 = 34 and as it is a negative number it would be -23 - 11 = -34 which makes it -34° C.

(ii) We know that the temperature now is -45° C, we need to find out how much the temperature had fallen in the 4 hours which had passed. So what we do is essentially add it considering its a negative number so we add -34 by 11 which equals -45. We do this so we can find out how much the temperature had dropped within the 4 hours and as we know that we needed to add 11 to the previous temperature (-34° C) it means that the temperature has dropped by 11° C.

The length of the rafter as detailed in the question is approximately; 22.80 yards

The formula for Pythagoras theorem is;

a² + b² = c²

where;

a and b are adjacent and opposite sides of the triangle formed

c is the hypotenuse

Now, a rafter is a sloped member of a roof structure. Thus, if the rafter is raised to a height of 18 yeards, it means that is the vertical height of the top of the rafter to the bottom of the kingpost.

Now, if half the length run is 14 yards, it means that half of the tie beams is 14 yards. Thus, from the base of the rafter to the center of the tie beams is 14 yards. Thus, we will use Pythagoras theorem to find the length of the rafter.

c = √(14² + 18²)

c = √520

c = 22.80 yards

Suppose that a probability is approximated to be zero based on empirical results, this does not mean that the event is​ impossible.

The likelihood that an event will occur is defined by probability. There are many instances in real life where we may need to make predictions about how something will turn out. The outcome of an event may be known to us or unknown to us.

By simply dividing the favorable number of possibilities by the entire number of possible outcomes, the probability of an occurrence can be determined using the probability formula. Because the favorable number of outcomes can never exceed the entire number of outcomes, the chance of an event occurring might range from 0 to 1.

Answer:

This is a educated guess, but x is 80 and y is 100.

Step-by-step explanation:

My logic here is that the triangles are the same because of all the congruent lines and stuff. But from there, you know that both the right and the left side are 40 degrees. You know the total degree of a triangle is 180 so 180 - 40 - 40 is 100. So the final angle is 100. If you look at x, its on the outside, but on a line. If you can imagine a circle, its half, so its a 180 degrees total. Then its 180 = x + 100. So x is 80. And then by that same logic its y = 100.
