Answer:
(2) $1,699.50
Step-by-step explanation:
A(t) = P(1 + r/n)^nt
1500(1 + .025/12)^5*12
= $1699.50
$1,699.50 represents the value of an investment with a principal of $1500 with a nominal interest rate of 2.5% compounded monthly after 5 years.
What is compound interest?Compound interest is the interest on savings calculated on both the initial principal and the accumulated interest from previous periods.
Given that an investment with a principal of $1500 with a nominal interest rate of 2.5% compounded monthly after 5 years,
Amount = P(1+r/n)^nt
= 1500(1+0.25/12)^5*12
= $1699.50
Hence, $1,699.50 represents the value of an investment with a principal of $1500 with a nominal interest rate of 2.5% compounded monthly after 5 years.

proportions in similar triangles. need help
Answer:
x = 6
Step-by-step explanation:
The angle bisector divides the triangle sides proportionally:
(6x -1)/42 = (10x +5)/78
13(6x -1) = 7(10x +5) . . . . multiply by 546 (the LCM of 42 and 78)
78x -13 = 70x +35 . . . . . eliminate parentheses
8x = 48 . . . . . . . . . . . . . . add 13-70x
x = 6 . . . . . . . . . . . divide by 8

Variance is average of squared error of observations from mean. The variance of given data is 5.2
How to calculate variance of a given data set?Variance is average of squared error of observations from mean.
If the data set is composed of n elements,its ith element is [tex]x_i[/tex] , and mean of the data set is [tex]\overline{x}[/tex] ,then its variance is given as:
[tex]\sigma^2 = \dfrac{1}{n} \sum_{i=1}^n(x_i-\overline{x})^2[/tex]
The given data set is 4,7,4,10,5
Thus, n = 5 (total 5 observations (data values) )
Their mean is [tex]\overline{x} = 6[/tex] (it is taken as 'm', but for ease with formula, take it as [tex]\overline{x}[/tex] )
Thus, their variance is calculated as:
[tex]\sigma^2 = \dfrac{1}{n} \sum_{i=1}^n(x_i-\overline{x})^2 \\\\\sigma^2 = \dfrac{(4-6)^2 + (7-6)^2 + (4-6)^2 + (10-6)^2 +(5 - 6)^2}{5} \\\\\sigma^2 = \dfrac{4 + 1 + 4 + 16 + 1}{5} = \dfrac{26}{5} = 5.2[/tex]
Thus,
The variance of given data is 5.2

The equation for the pH of a substance is pH = –log[H ], where H is the concentration of hydrogen ions. Which equation models the concentration of hydrogen ions (H ) of a solution whose pH is 7. 2?.
Equation models the concentration of hydrogen ions (H ) of a solution whose pH is 7.2 is,
[tex][H^+ ]=\dfrac{1}{10^{7.2}}[/tex]
What is pH value?The pH value is the measurement of the water, as it is acidic or basic in nature and amount of it. If the value of pH value is more than 7, the water is basic in nature and if less than 7, the water is acidic.
Given information-
The equation for the pH of a substance is,
[tex]pH = -\log[H^+ ],[/tex]
Here, [tex]H[/tex]hydrogen ions.
The pH value of the solution is 7.2.
The pH value of the solution is given, and the concentration of hydrogen ions has to be find out (in equation model form).
The given equation for pH of the substance is,
[tex]pH = -\log[H^+ ],[/tex]
It can be written as,
[tex]-pH = \log[H^+ ],[/tex]
The pH value of the solution is 7.2. Put the value as,
[tex]-7.2 = \log[H^+ ][/tex]
Rewrite the above equation as,
[tex]\log[H^+ ]=-7.2[/tex]
Using the log property the, above equation can be written as,
[tex][H^+ ]=10^{-7.2}[/tex]
Solve it further as,
[tex][H^+ ]=\dfrac{1}{10^{7.2}}[/tex]
[tex][H^+ ]=6.3095\times10^{-8}[/tex]
Thus, equation models the concentration of hydrogen ions (H ) of a solution whose pH is 7.2 is,
[tex][H^+ ]=\dfrac{1}{10^{7.2}}[/tex]

8 A circle passes through the points (0, 2) and (0,8) and its centre lies on the line
x=4.
Draw a sketch and find the equation of the circle.
Step-by-step explanation:
A circle that passes through point 0,2 and (0,8) and has a center that lies on x=4 is what given.
So we know is center (4,p) for some number p,
Since the points on circumference of the circle have the same x value, then we know that the y coordinate of the center must be the midpoint of the circumferences' y coordinates.
Why?
A circle is not a function since it doesn't pass the vertical line test. And the standard form of a circle is
[tex] {x}^{2} + {y}^{2} = {r}^{2} [/tex]
With center (0,0).
Consider the equation
[tex] {x}^{2} + {y}^{2} = 9[/tex]
The radius is 3 so two points with x coordinate 0 is
(0,3) and (0,-3). And the midpoint of them is (0,0) which is the center. Which is the defining trait of all circles.
Now, back on hand, our the midpoint of 2 and 8 is 5 so our center is
(4,5).
Now, we must find the radius. We use distance formula.
For (4,5) and (0,8).
[tex]d = \sqrt{(8 - 5) {}^{2} + ({0 - 4) {}^{2} } } [/tex]
[tex]d = \sqrt{3 {}^{2} + {4}^{2} } [/tex]
[tex]d = \sqrt{25} [/tex]
[tex]d = 5[/tex]
So our radius is 5.
So now we use the equation of center h,k.
[tex](x - h) {}^{2} + (y - k) {}^{2} = {r}^{2} [/tex]
H is 4
K is 5
[tex](x - 4) {}^{2} + (y - 5) {}^{2} = 25[/tex]
Above is sketch of graph.
