Find the Rate. (Round to the Nearest Tenth)
Principal = $900
Time = 1 year
Interest = $76.50

Answer:

Step-by-step explanation:

The simple interest can be calculated using the formula:

I = P * r * t

where:

P = principal amount = $575

r = annual interest rate = 6.5% = 0.065

t = time period = 10 years

I = 575 * 0.065 * 10

I = $373.75

The new balance can be found by adding the interest to the principal:

New balance = Principal + Interest

New balance = $575 + $373.75

New balance = $948.75

Rounded to the nearest cent, the new balance is $948.75.

If the bacteria in a dish that contains 2 bacteria quadruple every 16 minutes can be represented by the expression 2×4t/16, an equivalent expression for the number of bacteria in the dish for any time, t, in minutes is B. 8t/16.

An equivalent expression depicts two algebraic expressions that have the same value when the values for the variables are plugged in.

An algebraic expression is the combination of variables, values, constants, and numbers using mathematical operands without the equal symbol (=).

2×4t/16 = 8t/16

2×4t/16 ≠ 4t8

2×4t/16 ≠ 2×2t8

The prove that triangle ABE is congruent to triangle CDE is given below

Generally, To prove that triangle ABE is congruent to triangle CDE, we need to show that they have the same size and shape.

First, we can see that angle AED and angle CEB are opposite angles and therefore congruent, since AB || DC.

Also, since line AB = line DC, we know that segment AE is congruent to segment CE and segment BE is congruent to segment DE.

Using these congruent sides and the congruent angle, we can apply the Side-Angle-Side (SAS) congruence criterion to conclude that triangle ABE is congruent to triangle CDE.

Therefore, we have proven that triangle ABE is congruent to triangle CDE.

Answer:

Step-by-step explanation:

To calculate the present value (PV) and future value (FV) of the cash flow stream, we can use the following steps:

Calculate the present value of each cash flow using the formula:

PV = CF / (1 + r)^n

where CF is the cash flow, r is the annual interest rate, and n is the number of years until the cash flow is received.

For the first three cash flows of $150 at the end of each of the next 3 years, assuming a starting point of Year 0, we have:

PV1 = $150 / (1 + 0.11)^1 = $134.59 (Year 1)

PV2 = $150 / (1 + 0.11)^2 = $120.75 (Year 2)

PV3 = $150 / (1 + 0.11)^3 = $107.99 (Year 3)

For the cash flow of $250 at the end of Year 4:

PV4 = $250 / (1 + 0.11)^4 = $165.14

For the cash flow of $300 at the end of Year 5:

PV5 = $300 / (1 + 0.11)^5 = $179.34

For the cash flow of $500 at the end of Year 6:

PV6 = $500 / (1 + 0.11)^6 = $277.12

Add up the present values of each cash flow to find the present value of the entire stream:

PV = PV1 + PV2 + PV3 + PV4 + PV5 + PV6

PV = $134.59 + $120.75 + $107.99 + $165.14 + $179.34 + $277.12

PV = $985.93

Therefore, the present value of the cash flow stream is $985.93.

To find the future value of the cash flow stream, we can simply add up the cash flows and then apply the future value formula:

FV = CF x [(1 + r)^n - 1] / r

where CF is the sum of the cash flows, r is the annual interest rate, and n is the number of years from the present until the future value is calculated.

CF = $150 x 3 + $250 + $300 + $500 = $1,100

n = 6 (assuming a starting point of Year 0)

FV = $1,100 x [(1 + 0.11)^6 - 1] / 0.11

FV = $2,525.72

Therefore, the future value of the cash flow stream is $2,525.72.

$7,008 is the future value of a 2-year investment of $6,525 into a simple interest rate account with an annual interest rate of 3.7%.

percentage, a relative value indicating hundredth parts of any quantity.

The formula to calculate the future value of an investment with simple interest is:

FV = P(1 + rt)

where FV is the future value, P is the principal amount, r is the annual interest rate expressed as a decimal, and t is the time period in years.

P = $6,525

r = 0.037

t = 2 years

Plugging these values into the formula, we get:

FV = $6,525(1 + 0.037×2)

FV = $6,525(1.074)

FV = $7,008.

The value of sin (x/2) is -√(26/27).

The value of cos (x/2) is -√(2/27)

The value of tan (x/2) is 1/12.

We know that sin(x) = -2/27 in Quadrant 3, which means that x lies between 180 degrees and 270 degrees.

a. To find sin(x/2), we can use the half-angle formula:

sin(x/2) = ±√[(1-cos(x))/2]

Since x lies in Quadrant 3, we know that cos(x) is negative. To find cos(x), we can use the Pythagorean identity:

sin²(x) + cos²(x) = 1

(-2/27)² + cos²(x) = 1

cos²(x) = 1 - (-2/27)²

cos(x) = -√(1 - (-2/27)²)

cos(x) = -25/27

Now we can substitute cos(x) into the half-angle formula:

sin(x/2) = ±√[(1-(-25/27))/2]

sin(x/2) = ±√[(27/27 + 25/27)/2]

sin(x/2) = ±√[52/54]

sin(x/2) = ±√(26/27)

Since x is in Quadrant 3, sin(x/2) is negative.

Therefore;

sin(x/2) = -√(26/27)

b. To find cos(x/2), we can use the half-angle formula:

cos(x/2) = ±√[(1+cos(x))/2]

Again, we know that cos(x) is negative, so we can use the value we found earlier:

cos(x/2) = ±√[(1-25/27)/2]

cos(x/2) = ±√[2/27]

Since x is in Quadrant 3, cos(x/2) is also negative.

Therefore;

cos(x/2) = -√(2/27)

c. Finally, to find tan(x/2), we can use the identity:

tan(x/2) = sin(x)/(1+cos(x))

We already know sin(x) and cos(x), so we can substitute them in:

tan(x/2) = (-2/27)/(1-25/27)

tan(x/2) = (-2/27)/(-24/27)

tan(x/2) = 1/12

Therefore,

tan(x/2) = 1/12

The two points with an x-coordinate of 2 and a distance of 5 from (-2, -4) are: (2, -4 + 2√13) and (2, -4 - 2√13)

What is distance formula?

Distance is a measurement of how far away two things or locations are, either numerically or occasionally qualitatively.

Distance formula: [tex]distance = \sqrt{((x2 - x1)^2 + (y2 - y1)^2)}[/tex]

We can solve this problem using the distance formula, which gives us the distance between two points in a plane:

[tex]distance = \sqrt{((x2 - x1)^2 + (y2 - y1)^2)}[/tex]

Let (x, y) be a point with an x-coordinate of 2. Then we can write the distance from (-2, -4) to (x, y) as:

[tex]distance = \sqrt{((x - (-2))^2 + (y - (-4))^2)}[/tex]

Simplifying this expression, we get:

[tex]distance = \sqrt{((x + 2)^2 + (y + 4)^2)}[/tex]

We know that the distance between (-2, -4) and (x, y) is 5. Therefore, we can write:

[tex]\sqrt{((x + 2)^2 + (y + 4)^2)} = 5[/tex]

Squaring both sides, we get:

[tex](x + 2)^2 + (y + 4)^2 = 25[/tex]

Expanding the left side, we get:

[tex]x^2 + 4x + 4 + y^2 + 8y + 16 = 25[/tex]

Simplifying this expression, we get:

[tex]x^2 + 4x + y^2 + 8y - 5 = 0[/tex]

To find all points with an x-coordinate of 2 that satisfy this equation, we can substitute x = 2 and simplify the resulting equation:

[tex]2^2 + 4(2) + y^2 + 8y - 5 = 0[/tex]

Simplifying this equation, we get:

[tex]y^2 + 8y + 3 = 0[/tex]

We can solve this quadratic equation using the quadratic formula:

y = (-b ± sqrt(b^2 - 4ac)) / 2a

where a = 1, b = 8, and c = 3.

Plugging in these values, we get:

y = (-8 ± sqrt(8^2 - 4(1)(3))) / 2(1)

Simplifying this expression, we get:

y = (-8 ± √52) / 2

y = (-8 ± 2√13) / 2

y = -4 ± √13

Therefore, the two points with an x-coordinate of 2 and a distance of 5 from (-2, -4) are: (2, -4 + 2√13) and (2, -4 - 2√13)

(5t - 4)(t - 1) = 0

From this equation, we can see that either 5t - 4 = 0 or t - 1 = 0. Solving for t in each case, we get:

5t - 4 = 0 ==> t = 0.8 seconds

t - 1 = 0 ==> t = 1 second

It is believed that the four fundamental operations, often referred to as "arithmetic operations", can describe all real numbers. The four mathematical operations that produce the quotient, product, sum, and difference are divide, multiply, add, and subtract.

We are given a graph determining the types of occupations of the 1,200 residents of a town.

Percentage of residents having occupation in government is:

100% - 25% - 15% - 25% - 30% = 5%

Number of residents having occupation in industry is as follows:

25% of 1200 = 300

Similarly, number of residents having occupation in government is:

5% of 1200 = 60
