The surface area of the given composite solid is calculated as: 200.24 square units.
How to Find the Surface Area of the Composite Solid?Surface area of the composite solid = surface area of rectangular prism + surface area of cylinder - 2(area of the base of the cylinder)
Surface area of rectangular prism = length * width * height = 10 * 3 * 5
= 150 square units.
Surface area of cylinder = 2πr(h + r)
height (h) = 4
Radius (r) = 2
Plug in the values:
Surface area of cylinder = 2 * 3.14 * 2(4 + 2) = 75.36 square units
Area of the base of the cylinder = πr² = 3.14 * 2²
= 12.56 square units
Thus, we have:
Surface area of the composite solid = 150 + 75.36 - 2(12.56) = 200.24 square units.

If you want get 60000 in 8 years how much do you need to deposit in the bank today if the account pays an interest rate of 9%
Answers
Answer:
FV = PV x (1 + r)^n
where:
FV = future value
PV = present value (the amount to be deposited today)
r = interest rate per period (in this case, per year)
n = number of periods (in this case, 8 years)
Plugging in the given values, we get:
$60,000 = PV x (1 + 0.09)^8
Simplifying this equation:
PV = $60,000 / (1 + 0.09)^8
PV = $60,000 / 1.999^8
PV = $60,000 / 3.058
PV = $19,602.68
Therefore, the amount that needs to be deposited in the bank today to accumulate $60,000 in 8 years with an interest rate of 9% is $19,602.68.

A man drove 14 miles directly east from his home, made a left turn at an intersection, and then traveled 7 miles north to his place of work. If a road was made directly from his home to his place of work, what would its distance be to the nearest tenth of a mile?
Answers
The distance traveled east and the distance traveled north form the two legs of a right triangle, and the distance we want to find is the hypotenuse.
Using the Pythagorean theorem, we have:
distance^2 = (14 miles)^2 + (7 miles)^2
distance^2 = 196 + 49
distance^2 = 245
distance = sqrt(245)
distance = 15.62 miles (rounded to the nearest tenth)
Therefore, the distance between the man's home and his place of work, if a road was made directly between them, would be approximately 15.6 miles.

The reduced form of the matrix is [tex]\begin{bmatrix}1 &-\frac{4}{7} &\frac{4}{7} \\0& 11& 79\end{bmatrix}[/tex]
A matrix is a rectangular array of numbers arranged in rows and columns. In linear algebra, matrices can be used to represent linear transformations and solve systems of linear equations.
In the given matrix, we need to perform a row operation to get a 1 in row 1, column 1. Row operations are operations performed on the rows of a matrix to transform it into another matrix that is equivalent in terms of solutions to a system of linear equations.
The three types of row operations are:
Swapping two rows.
Multiplying a row by a non-zero constant.
Adding a multiple of one row to another row.
To perform this row operation, we first multiply row 1 by 12 to get a multiple of 12 in the first column of row 1:
[tex]\begin{bmatrix}84 &-48 &96 \\-12& 7& -13\end{bmatrix}[/tex]
Next, we add row 1 to row 2 multiplied by 2 to get a 0 in column 1 of row 2:
[tex]\begin{bmatrix}84 &-48 &96 \\0& 11& 79\end{bmatrix}[/tex]
Finally, we can divide row 1 by 84 to get a 1 in row 1, column 1:
[tex]\begin{bmatrix}1 &-\frac{4}{7} &\frac{4}{7} \\0& 11& 79\end{bmatrix}[/tex]
Now we have a 1 in row 1, column 1, and the matrix is in row echelon form.

Answers
The distance from town A that they will be, when they will pass each other is 44 4/9 .
How can the distance be calculated?It should be noted that time traveled in each segment is constant, which implies that in this case the average speed can be regarded as the simple mean of speeds. An in the case whereby the distance traveled in each segment is constant, average speed can be described to be the reciprocal of simple mean .
This can be expressed mathematically as
Average speed = Reciprocal [ 1/40 & 1/50].

5. The population, P, of a city has grown according to the mathematical model P = 50 000(1.15), where t
is the number of years since 2005.
Using a graphing tool or by hand answer the questions below.
a) What was the population of the town in 2005?
I
b) In what year will the population exceed 100 000?
Answers
Answer: Therefore, the population will exceed 100,000 in the year 2005 + 10.73 ≈ 2016.
Step-by-step explanation: a) The population of the town in 2005 is given by the formula, where t = 0 since 2005 is the starting year:
P = 50,000(1.15)^0 = 50,000
Therefore, the population of the town in 2005 was 50,000.
b) We need to find the value of t when the population P exceeds 100,000:
100,000 = 50,000(1.15)^t
Divide both sides by 50,000:
2 = 1.15^t
Take the natural logarithm of both sides:
ln 2 = ln (1.15^t)
Apply the power rule of logarithms:
ln 2 = t ln 1.15
Divide both sides by ln 1.15:
t = ln 2 / ln 1.15
Using a calculator, we get:
t ≈ 10.73

|x+3| if x>5
Answers
The expression without the absolute value symbol is:
|x + 5| = x + 5, if x > 5
|x - 5| = 0, if x = 5
|x - 5| = 5 - x, if x < 5
Since, An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.com
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
|(x + 3) | if x > 5
This can be written as,
= |x + 3|
Now,
|x + 5| = x + 5, if x > 5
|x - 5| = 0, if x = 5
|x - 5| = 5 - x, if x < 5
Thus,
The expression without the absolute value symbol is:
|x + 5| = x + 5, if x > 5

A. 0.48%
B. 4.8%
C. 0.325%
D. 3.25%
Answers
Answer:
D. 3.25%
Step-by-step explanation:
The formula for simple interest is:
I = Prt
where I is the interest earned, P is the principal, r is the annual interest rate, and t is the time in years.
We are given that:
I = $1430
P = $5500
t = 8 years
Substituting the values:
$1430 = $5500 * r * 8

r = $1430 / ($5500 * 8)
r = 0.0325 or 3.25%

Hence, the darkened sector covers an area of roughly [tex]10.55 km^2[/tex] as circle's radius is 7 km, and the shaded sector's central angle is 154 degrees .
what is radius ?The radii of a circle in geometry is the separation between any two points on the circle's circumference. It is frequently used to describe how far apart two points are. One of a circle's most crucial characteristics is its radius, which is taken into account when calculating a circle's circumference, area, and diameter. The distance around a circle that passes through its centre, or its diameter, is equal to half of its radius. Other shapes like spheres, cylindrical, and cones can also be described using the radius. The radius here means the distance from the shape's centre to any point on its perimeter.
given
The following formula must be used to determine a sector's area:
A = (θ/360)[tex]\pi r^2[/tex]

The circle's radius is 7 km, and the shaded sector's central angle is 154 degrees, according to the provided figure. When these values are added to the formula, we obtain:
