Step-by-step explanation:
An investor wants to save money to purchase real estate. She buys an annuity with yearly payments that earn 5.3% interest compounded annually payments will be made at the end of each year find the total value of the annuity in 16 years if each yearly payment is 693.
The total value of the annuity in 16 years, with yearly payments of $693 and an interest rate of 5.3% compounded annually, is approximately $12,739.62.
To calculate the total value of the annuity in 16 years, we can use the formula for the future value of an annuity:
FV = P * ((1 + r)^n - 1) / r
Where:
FV is the future value of the annuity,
P is the yearly payment,
r is the interest rate per compounding period, and
n is the number of compounding periods.
In this case, the yearly payment (P) is $693, the interest rate (r) is 5.3% or 0.053, and the number of compounding periods (n) is 16.
Let's substitute these values into the formula and calculate the total value of the annuity:
FV = 693 * ((1 + 0.053)^16 - 1) / 0.053
FV = 693 * (1.053^16 - 1) / 0.053
Using a calculator, we can evaluate the expression inside the parentheses:
1.053^16 ≈ 1.9738
Substituting this value back into the formula:
FV = 693 * (1.9738 - 1) / 0.053
FV = 693 * 0.9738 / 0.053
FV ≈ 12739.62
Therefore, the total value of the annuity in 16 years, with yearly payments of $693 and an interest rate of 5.3% compounded annually, is approximately $12,739.62.

you are pouring canned soda into a cylinder cylinder that is 12 cm tall and a diameter of 6.5 cm The picture is 36 cm tall and has a diameter of 20 cm how many cans of soda will the picture hold
We are going to assume that the picture of 36 tall and has a diameter of 20 cm is also a cylinder.
To answer this question, we need to know the formula to find the volume of a cylinder:
\(V_{\text{cylinder}}=\pi\cdot r^2\cdot h\)Where
• r is the radius of the base of the cylinder.
,• h is the height of the cylinder.
,• pi = 3.14159265358979...
From the question, we have:
The dimensions of the first cylinder are:
h = 12cm
D = 6.5cm.
Since the radius of a circle is half of its diameter, then, we have that the radius of this cylinder is 6.5cm/2 = 3.25cm.
Then, r = 3.25cm.
Then, the volume of this cylinder is:
\(V_{\text{cylinder}}=\pi\cdot(3.25\operatorname{cm})^2\cdot12\operatorname{cm}=\pi\cdot10.5625\operatorname{cm}\cdot12\operatorname{cm}=126.75\pi cm^3\)Now, we need to find the volume of the cylinder of the picture following the same procedure:
h = 36cm
D = 20cm ---> r = D/2 ---> r = 20cm/2 ---> r = 10cm
\(V_{\text{cylinderpicture}}=\pi\cdot(10\operatorname{cm})^2\cdot36\operatorname{cm}=\pi\cdot100\operatorname{cm}^2\cdot36\operatorname{cm}\)Then, we have that the volume of the cylinder of the picture is:
\(V_{\text{cylinderpicture}}=3600\pi cm^3\)Thus, we have that we poured a canned soda into a cylinder of 147pi cm^3. How many cans of soda will hold the cylinder of the picture? We need to divide the total volume of the cylinder of the picture by the volume of the first cylinder (the one which contains the canned soda). Then, we have:
\(N_{\text{cannedsoda}}=\frac{V_{\text{cylinderpicture}}}{V_{\text{cylinder}}}=\frac{3600\pi cm^3}{126.75\pi cm^3}\Rightarrow N_{cannedsoda}=28.402367\)Therefore, the cylinder of the picture will hold about 28.40 canned sodas.

If the sides of triangle A have lengths of 30 cm, 40 cm, and 50 cm, what are the lengths of the sides of triangle D?
Answer:
60cm 70 cm 80cm
Step-by-step explanation:
One possible set of side lengths for triangle D is 40 cm, 50 cm, and 30 cm. However, there are infinitely many other sets of side lengths that would also satisfy the condition that triangle D is similar to triangle A.
What is the similarity?Two triangles are said to be similar if they have the same shape, but not necessarily the same size. That is, their corresponding angles are equal and their corresponding sides are proportional in length.
Triangle A is a right triangle with sides of length 30 cm, 40 cm, and 50 cm, where 50 cm is the length of the hypotenuse (the side opposite the right angle).
Triangle D is similar to triangle A, which means that their corresponding sides are proportional in length.
Using these observations, we can determine some general relationships between the sides of triangles A and D. Let's denote the sides of triangle D as x, y, and z:
Since triangle D is similar to triangle A, we know that the ratio of corresponding side lengths is the same for both triangles. In other words, we can write:
x/30 = y/40 = z/50
Since the sides of the triangle, A have lengths 30 cm, 40 cm, and 50 cm, we can use these values to find the ratio of the sides:
40/30 = 4/3 and 50/30 = 5/3
Multiplying these ratios by a common factor will give us the corresponding side lengths for triangle D. For example, we could choose to multiply by 30 to get:
x = 4/3 x 30 = 40
y = 5/3 x 30 = 50
z = 30
So one possible set of side lengths for triangle D is 40 cm, 50 cm, and 30 cm. However, there are infinitely many other sets of side lengths that would also satisfy the condition that triangle D is similar to triangle A.

What is the sum of the measures of the interior angles of a regular polygon if each exterior 120.
The sum of the measures of the interior angles of the regular polygon is 180 degrees.
If each exterior angle of a polygon measures 120 degrees, then each interior angle of the polygon measures 180 - 120 = 60 degrees. This is because the sum of an exterior angle and its corresponding interior angle is always 180 degrees.
Let n be the number of sides of the regular polygon. The sum of the measures of the interior angles of a polygon with n sides can be found using the formula:
Sum of interior angles = (n - 2) * 180 degrees
For a regular polygon, all interior angles have the same measure, so we can write:
n * 60 degrees = (n - 2) * 180 degrees
Simplifying this equation, we get:
60n = 180n - 360
120n = 360
n = 3
Therefore, the polygon is an equilateral triangle, and the sum of its interior angles is:
Sum of interior angles = (n - 2) * 180 degrees = (3 - 2) * 180 degrees = 180 degrees

When we add two negative numbers, the result will be negative.
When we add a negative and a positive number, the result can be positive, negative, or equal to zero.
Take the absolute values of both numbers (disregard their signs). If the number that was positive is greater, then the result will be positive.If the number that was negative is greater, then the result will be negative.If the two numbers are equal, then the result will be 0.When we add two positive numbers, the result will be positive.
Solving the Questionj + k
These are both negative numbers. We know this because they are both to the left of 0. When we add two negative numbers, we will get a result that is less than 0.
Less than 0k + n
k is a negative number while n is a positive number.
Notice that on the number line, k and n appear to be at a equal distance away from 0. This means that if we were to take their absolute values, they would be equal.
This means that adding k and n would result in an answer of 0.
Equal to 0m + n
m is a negative number while n is a positive number.
Notice that on the number line, n appears to be further away from 0 than m is. m is very close to 0.
This means that the absolute value of n would be greater than that of m. The result would therefore be positive
Greater than 0k + m
Both these numbers are negative. Adding them would produce a negative result.

1) In(2x²-x)
The derivative is f'(x) = (4x - 1) / (2x² - x).
To find the derivative of the function f(x) = ln(2x² - x), we can use the chain rule.
Begin by identifying the function to be differentiated, which is f(x) = ln(2x² - x).
Apply the chain rule, which states that if we have a composition of functions, f(g(x)), the derivative is given by (f'(g(x))) g'(x).
Let's consider the inner function g(x) = 2x² - x.
To differentiate g(x), we need to apply the power rule and the constant rule. The derivative of 2x² is 4x, and the derivative of -x is -1.
Now, we differentiate the outer function f'(g(x)). The derivative of ln(x) is 1/x.
Finally, we multiply the derivatives obtained in steps 3 and 4. Thus, the derivative of f(x) = ln(2x² - x) is:
f'(x) = (1 / (2x² - x)) * (4x - 1)
Simplifying further, we have:
f'(x) = (4x - 1) / (2x² - x)

Drawing a number divisible by 3 then drawing a 1
Answer:
Step-by-step explanation:
The probability of drawing a number that is divisible by 3 is 1/3, since there are 3 numbers (3, 6, and 9) out of the 9 possible numbers (1, 2, 3, 4, 5, 6, 7, 8, and 9) that are divisible by 3.
The probability of drawing a 1 after drawing a number that is divisible by 3 is 1/10, since there is only one 1 among the 10 possible digits (0-9) that could be drawn after the first number.
To find the probability of both events happening together (drawing a number divisible by 3 and then drawing a 1), we need to multiply the probability of the first event by the probability of the second event. Therefore, the probability of drawing a number divisible by 3 and then drawing a 1 is:
(1/3) x (1/10) = 1/30
So the probability of drawing a number divisible by 3 and then drawing a 1 is 1/30, or approximately 0.0333, or about 3.33%
