a stock investment of 160 shares paid a dividend of $584 at this rate what dividend would be paid on 270 shares of stock
Answer:
4985.5
Step-by-step explanation:
To start, lets show what we know
160x = 584 where x is the amount paid per stock investment
Find: 270x
Now lets find x
160x = 584
160x/160 = 574/160
x = 3.65
270x = 270(3.65) = 985.5
Here, we have our answer of $985.5 for 270 shares of stock.

Calculate the volume of a right cylinder with a base area of 21.23 cenitimeters and
a height of 3.2 centimeters to the nearest hundredth of a centimeters).
Answer: 67.94 cm^2
Step-by-step explanation:
The volume of a cylinder equals the base area multiplied by the height.
Therefore, the volume would be equal to 21.23cm*3.2cm = 67.936 cm^2
Rounded to the nearest hunderedth, the volume would be 67.94 cm^2
Beatrice has at least one quarter, one dime, one nickel, and one penny. She has exactly 13 coins total. Beatrice also has a total value of 92 cents. How many different sets of coins can she have?
The number of different sets of coins that she can have is; Two sets which are; (0, 7, 4, 2) or (1, 3, 7, 2)
What is the combination of coins?Let the numbers of coins be;
Quarter; QDimes: DNickel; NPenny; PWe have:
Q + D + N + P = 13
We know that;
25 quarters make 1 cent
10 dimes makes one cent
5 nickels make one cent
1 penny makes one cent
Thus;
25Q + 10D + 5N + P = 92
P will have to be 2 because the others will give a value with the unit digit as 0. Thus;
Q + D + N = 11 ----(1)
25Q + 10D + 5N + 2 = 92
25Q + 10D + 5N = 90
Divide through by 5 to get;
5Q + 2D + N = 18 (2)
Subtract eq (1) from eq (2) to get;
4Q + D = 7
Let us put D = 7 and Q = 0, and so from eq (1), N = 4
The set here is now; (Q, D, N, P) = (0, 7, 4, 2)
Let us put D = 3, Q = 1, and from eq (1), N = 7
The set here is now; (Q, D, N, P) = (1, 3, 7, 2)
If D = 6, 5, 4, 2, 1, 0, then Q is not an integer, these can be ignored.

Trisha ran 10 km in 2.5h. Jason ran 7.5 km in 2h. Olga ran 9.5 km in 2.25h. Who had the fastest average speed.
Hello!
10 km in 2.5h.
2,5h = 150mn
150mn -> 10km
1 mn -> 10/150
60mn -> (10*60)/150
=>4km/h
Jason ran 7.5 km in 2h.
7,5 /2 =3,75
=> 3,75km/h
Olga ran 9.5 km in 2.25h.
2,25h = 120 + 0,25 * 60 =>135mn
135mn -> 9,5km
1mn -> 9,5/ 135
60mn -> (9,5*60)/ 135 =>4,22km/h
Who had the fastest average speed.: Olga

Evaluate (6 +2i) / (3-i).
Answer:
2(4 + 3i) / 5
Step-by-step explanation:
(6 + 2i) (3 + i) / (3 - i) (3 + i)
=> 18 + 12i + 2i² / 9 - i²
=> 16 + 12i / 10
=> 8 + 6i / 5
=> 2(4 + 3i) / 5
Answer:
(6 +2i) / (3-i) = (6+2i)/(3-i) x (3+i)/(3+i) = (6+2i)(3+i) / (3-i)(3+i) = 6(3+i)+2i(3+i) / (3)^2-(i)^2 = 18+6i+6i+2i^2 / 9-i^2 = 18+12i+2i^2 / 9-i^2 = 6+12i+2i^2 / 3-i^2 = 2+12i+2i^2 / 1-i^2 = 2+12i+2 / 1 = 4+12ianswer.

write the equation for the line in standard form
Step-by-step explanation:
a parallel line has the same slope (inclination).
the slope is always the factor of x in the line equation, which is 1/2.
the standard form of a line is
y = ax + b
we know a = 1/2.
to get b we use the given point :
-5 = 1/2 × -6 + b
-5 = -3 + b
b = -2
so our line equation is
y = (1/2)x - 2
but if your teacher understands "standard form" as "point-slope" form (I don't, but others do), then we need to use
y - y1 = a(x - x1)
where (x1, y1) is a point on the line.
and that form would then be in our case
y - -5 = (1/2)(x - -6)
y + 5 = (1/2)(x + 6)

Unit activity: exponential and logarithmic functions
Part E
Compare the features of the graphs of functions f and g. Then use your observations to describe the
relationship between the domains and ranges of the two functions.
We will conclude that:
The domain of the exponential function is equal to the range of the logarithmic function.The domain of the logarithmic function is equal to the range of the exponential function.Comparing the domains and ranges.
Let's study the two functions.
The exponential function is given by:
f(x) = A*e^x
You can input any value of x in that function, so the domain is the set of all real numbers. And the value of x can't change the sign of the function, so, for example, if A is positive, the range will be:
y > 0.
For the logarithmic function we have:
g(x) = A*ln(x).
As you may know, only positive values can be used as arguments for the logarithmic function, while we know that:
[tex]\lim_{x \to \infty} ln(x) = \infty \\\\ \lim_{x \to0} ln(x) = -\infty[/tex]
So the range of the logarithmic function is the set of all real numbers.
So what we can conclude?The domain of the exponential function is equal to the range of the logarithmic function.The domain of the logarithmic function is equal to the range of the exponential function.If you want to learn more about domains and ranges, you can read:

Please help. I don’t understand what sample space is or how to get to the last answer.
Answer:
13/16
Step-by-step explanation:
A sample space is a collection or a set of possible outcomes of a random experiment.
I have created the sample space for these data and attached it. As you can see there are 16 possible outcomes.
To find the probability that the total showing is greater than 3, simply identify the number of values in the sample space that are greater than 3.
(I have highlighted these in yellow).
Therefore, P(X>3) = 13/16
What is the equation of a vertical line that passes through the point (3, -10)?
Question 1 options:
x = 3
x = -3
x = 10
x = -10
Answer: Choose the equation of the vertical line passing through the point (-2, 3). A vertical line goes up and down through point (-2, 3), so every point on the line will have the same x coordinate. For example, (-2, 0) and (-2, 1) and (-2, -1) all fall on that vertical line. Therefore, the equation for the line is x = -2 Choose the equation of the horizontal line that passes through the point (-5, 1). A horizontal line goes left and right through point (-5, 1), so every point on the line will have the same y coordinate. For example, (-1, 1) and (0, 1) and (1, 1) all fall on that horizontal line. Therefore, the equation for the line is y = 1.
Step-by-step explanation:
Answer:
x = 3
Step-by-step explanation:
The coordinate point is in the format (x, y)
Therefore, the x-value of (3, -10) is 3
So the equation of the vertical line is therefore x = 3

Continuously-
Monthly-
Semi-annually-

Answer:
See Picture. I made a 100.
Step-by-step explanation:
Weekly- $17253.46
Daily- $17254.01
Continuously- $17254.11
Monthly- $17251.29
Semi-annually- $17237.36
Quarterly- $17245.69
Compound interest is the addition of interest on the interest of the principal amount.
What is compound interest?Compound interest is the addition of interest on the interest of the principal amount. It is given by the formula,
[tex]A = P(1+ \dfrac{r}{n})^{nt}[/tex]
As it is given that the principal amount is $15,000; while the rate of interest is 2.8%, and the amount is invested for a period of 5 years.
A.) When the interest is charged weekly,
As we know that there are 52 weeks in a year, therefore, n = 52, substitute the values,
[tex]A = P(1+ \dfrac{r}{n})^{nt}\\\\A = 15000(1+ \dfrac{0.028}{52})^{52 \times 5}\\\\A = \$17,253.46[/tex]
B.) When the interest is charged daily,
As we know that there are 365 days in a year, therefore, n = 365, substitute the values,
[tex]A = P(1+ \dfrac{r}{n})^{nt}\\\\A = 15000(1+ \dfrac{0.028}{365})^{365 \times 5}\\\\A = \$19,554.55[/tex]
C.) When the interest is charged Continuously,
As we know that the formula for continuous compounding is given as,
[tex]A = Pe^{rt}[/tex]
Substitute the values, we will get,
[tex]A = 15000 \times (e^{0.024 \times 5})\\\\A= \$16,912.45[/tex]
D.) When the interest is charged Monthly,
As we know that there are 12 months in a year, therefore, n = 12, substitute the values,
[tex]A = P(1+ \dfrac{r}{n})^{nt}\\\\A = 15000(1+ \dfrac{0.028}{12})^{12\times 5}\\\\A = \$15211.23[/tex]
E.) When the interest is charged Semi-annually,
As we know that the interest is charged Semi-annually, therefore, n = 2, substitute the values,
[tex]A = P(1+ \dfrac{r}{n})^{nt}\\\\A = 15000(1+ \dfrac{0.028}{2})^{2\times 5}\\\\A = \$17,237.36[/tex]
F.) When the interest is charged Quarterly,
As we know that the interest is charged Quarterly, therefore, n = 4, substitute the values,
[tex]A = P(1+ \dfrac{r}{n})^{nt}\\\\A = 15000(1+ \dfrac{0.028}{4})^{4\times 5}\\\\A = \$17,245.7[/tex]
