Find the amount in a continuously compounded account for the given conditions.principal: $ 2000 annual interest rate: 5.1 % time: 3 years

Answers

The amount in a continuously compounded account for the given conditions is $2330.64 .

Compound interest is interest calculated on the principal and the interest accrued in previous periods. Compound interest is interest based on principal and interest accumulated over a period of time.If we specifically state that the quantity in question is "continuously composed", we must use the continuous constitutive formula which is given by [tex]A=Pe^{rt}[/tex]    ..... (1) where, P =  initial amount , A =  final amount , r = interest rate  , t = time , e is a mathematical constant with e ≈ 2.7183.

It is given that principal is 2000 , annual interest rate is 5.1 % , time is 3 years

Putting [tex]P=\$2000 , \ r= 5.1\% , \ t=3 \ years[/tex] in equation (1) , we get

  [tex]A=2000\times 2.71^{0.051 \times 3}\\A=200\times 2.71^{0.153}\\ \ A=2000\times1.1653\\A =\$2330.64[/tex]

Answers

The constant of proportionality for the relationship plotted, on the graph is 25 and the distance in 10 seconds is 250

How to find the constant of proportionality for the relationship plotted, on the graph?

The graph is the given parameter

On the graph, we have the following point

(x, y) = (2, 50)

The constant of proportionality for the relationship plotted, on the graph is represented with k, and the formula is

k = y/x

This gives

k = 50/2

Evaluate

k = 25

Substitute k = 25 in k = y/x

25 = y/x

When x = 10. we have

25 = y/10

This gives

y = 250

Hence, the constant of proportionality for the relationship plotted, on the graph is 25 and the distance in 10 seconds is 250

The measure of each of the
congruent angles of an isosceles
triangle is 9 less than 4 times the
vertex angle. Find the measures of all
the angles in the triangle.

Answers

Answer:

22°, 79° and 79°

Step-by-step explanation:

Let x  be the vertex angle and y each of the congruent angles.

The sum of all angles =180°

So x + y + y = 180

x + 2y = 180 ·········· Equation (1)

Given "The measure of each of the congruent angles of an isosceles triangle is 9 less than 4 times the vertex angle", the equation is

y = 4x - 9

Substitute for y in terms of x in equation 1

⇒ x + 2(4x - 9) = 180

⇒ x + 8x - 18 = 180

⇒ 9x - 18 = 180

⇒ 9x = 180 + 18

⇒ 9x = 198

⇒ x = 198/9 = 22

So vertex angle is 22°

Substituting for x in Equation 1:
22 + 2y = 180
2y = 180 - 22
2y = 158
y = 158/2
y = 79°

So each congruent angle is 79°


The initial value of a car is $ 25,000 . After one year, the value of the car is $ 21,250 . Write an exponential function to model the expected value of the car. Estimate the value of the car after 5 years.

Answers

The exponential function for the value of car is V = 25,000 × e^( r × T) and the value of the car after 5 years is $ 1109.26.

The original value of a car is $25,000.

The value of the car after one year is $21,250.

Let V be the value of the car after T years.

Let the rate at which the value of the car increase be r.

From, [tex]\[ A = Pe^{r \times T} \][/tex]

Then,

[tex]\[ V = 25,000 \times e^{ r \times T } \][/tex]

The value of the car after one year is $21,250.

[tex]\[ 21,250 = 25000 \times e^{ r \times T } \][/tex]

Divide both sides by 25000

[tex]\frac{21250}{25000} = e^{1 \times r }[/tex]

Now, taking the log of both sides

[tex]\[ \ln (21250/25000) =\ln e^{1 \times r} \][/tex]

By the property of logarithm,

[tex]\ln e^{(1 \times r)} = r[/tex]

Therefore,

㏑(21250/25000) = r

Now, the value of the car after 5 years will be:

[tex]\[ V = 25,000 \times e^{ r \times T} \]\\\\[/tex]

[tex]\[ V = 25000 \times e^{ \ln (\frac{21250}{25000} ) \times 5 } \][/tex]

V = 25000 × 0.4437053125

V = $ 1109.26

Solve. Check for extraneous solutions. √3 x+1 - √x+1=2

Answers

x=0 is an extraneous solution of the equation and x = 8 is not an extraneous solution of the equation.

√(3x+1) - √(x+1) = 2

√(3x+1) = 2 + √(x+1)

Squaring both the sides of the equation

(√(3x+1))² = (2 + √(x+1))²

3x + 1 = (2)² + (√(x+1))² + 2(2) (√(x+1))

3x + 1 = 4 + x + 1 + 4(√(x+1))

3x + 1 = 5 + x + 4(√(x+1))

2x - 4 = 4(√(x+1))

Squaring again on both the side of the equation, we get

(2x - 4)² = (4(√(x+1))²

4x² + 16 - 16x = 16x + 16

4x² - 32x = 0

4x(x - 8) = 0

4x = 0 and x - 8 = 0

x = 0 and 8

Check for Extraneous Solution by keeping value of x in the original equation √(3x+1) - √(x+1) = 2

Let x=0

√(3(0)+1) - √(0+1) = 2

0 ≠ 2

LHS ≠ RHS

x = 0 is an extraneous solution of the equation

Let x=8

√(3(8)+1) - √(8+1) = 2

Suppose z varies directly with x and inversely with y . If z is 1.5 when x is 9 and y is 4 , what is z when x is 6 and y is 0.5 ?

Answers

The required value of z using given conditions and functions is 7.92.

What is a function?

A function is defined as an expression or rule that specifies the relationship between two variables or objects, out of which one is dependent and the other is an independent variable. The image of each and every element is unique.

Calculation for the value of z

Given value of z = 1.5, x = 9, y = 4

Consider z as a function varying directly with x and inversely with y i.e.

z = kx / y        —-- 1

Putting the values of x, y, z, we get,

1.5 = k × 9 / 4

6 = 9 × k

k  = 6 / 9

k = 2 / 3 = 0.66

Now, calculating z for x = 6, k = 0.66 and y = 0.5, using function,

z = (0.66 × 6) / 0.5

= 3.96 / 0.5

= 7.92

Hence, the required value of z = 7.92.
