9 apples and 6 oranges cost $33
18 apples and 20 oranges cost $80

How much does 1 apple and 1 orange cost

Answers

apple: 2.50 orange: 1.75

The cost of each apple and each orange will be $2.5 and $1.75, respectively. The cost of 1 apple and 1 orange will be $4.25.

What is the solution to the equation?

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

9 apples and 6 oranges cost $33 and 18 apples and 20 oranges cost $80.

Let 'x' be the cost of each apple and 'y' be the cost of each orange. Then the equations are given as,

9x + 6y = 33               ...1

18x + 20y = 80          ...2

Multiply equation 1 by negative 2, then we have

-18x - 12y = - 66          ...3

Add equations 2 and 3, then we have

20y - 12y = 80 - 66

8y = 14

y = $1.75

Then the cost of each apple is calculated as,

9x + 6(1.75) = 33

9x = 33 - 7.5

9x = 22.5

x = $2.5

The cost of each apple and each orange will be $2.5 and $1.75, respectively.

The cost of 1 apple and 1 orange will be given as,

⇒ $2.5 + $1.75

⇒ $4.25

Find the equation of Straight line equally indined to the axes and cutting off an intercept 0-2 from the y-axis

Answers

The equation of the line is y = x - 2.

What is the equation of the line?

A straight line's general equation is y = mx + c, where m denotes the gradient and y = c denotes the point at which the line crosses the y-axis. On the y-axis, this value c is referred to as the intercept. Key Concept. Y = mx + c represents the equation of a straight line with gradient m and intercept c on the y-axis.

We have,

y-intercept(c) = −2 and

the line is equally inclined to the axis i.e., the same angle to the x-axis and y-axis(say)=θ

but the angle between the axes is 90°

2θ = 90° ⇒ θ = 45°

As slope and y-intercept are given.

The equation of a line is y = mx + c

c = -2 and

m = tan45°

as the line is equally inclined to the axes.

c = -2 and m = 1

Hence, the equation of the line is y = x - 2.

The amount borrowed is $66,000, the annual interest rate is 4 %, the number of payments per year is 12, the loan term is 20 years, and the payment amount is $10668.39.

What is compound interest?

Compound interest is applicable when there will be a change in the principle amount after the given time period.

For example, if you give anyone $500 at the rate of 10% annually then $500 is your principle amount. After 1 year the interest will be $50 and hence principle amount will become $550 now for the next year the interest will be $550, not $500.

The total amount paid is,

A = 4800[1 + 0.04/12]^(12 x 20)

A = $10668.39

Compound interest is that the interest on savings calculated on each the initial principal and therefore the accumulated interest from previous periods.

Main body:

Given :

rate = 6%

amount = $900

Total amount = $1800

Compounded monthly,

so formula becomes,

Total amount = amount (1+r/1200)^12t

T = A[tex](1+r/1200)^{12t[/tex]

1800 = 900 (1+6/1200)^12t

2 = (1+1/200)^12t

2 = 1.005^12t

taking log on both sides

log 2 = 12t *log 1.005

0.3/0.002 = 12t

Answers

Let (r,q) represent P's polar coordinates, with r being positive and 0 equaling q being pi/2. If so, r = 3m. And A = 0.20136

All points in a plane that are at a specific distance from a specific point, the center, form a circle.
Formula for the first circle: x²+ y² = 9

Formula for the second circle:

center is (0, 7.5) and the radius is 15/2, so

x² + (y - 7.5)² = (7.5)²

Combining these yields:

9 - y² + (y - 7.5)² = (7.5)²

9 - y² + y² - 15y + (7.5)² = 7.5²

9 - 15y = 0

y = 9/15 = 3/5

∴ y = 0.6

x² + y² = 9 = x² + (3/5)²

x² = 9 - (9/25)

x² = [(225 - 9)/25] = 216/25

∴ x = 2.9394

r = √(x² + y²) =

r = √[( 216/25) + (9/25)]

r = √(225/25) = 15/5
∴ r = 3

The x and y values appear to be accurate because this must be the same as the radius of the circle cantered at the origin.

sin(A) = y/r

sin(A) = (3/5)/3 = 1/5

Sin(A) = 0.2

What is a NPV  net present value ?

The difference between the current value of cash inflows and withdrawals over a period of time is known as net present value (NPV). To evaluate the profitability of a proposed investment or project, NPV is used in capital budgeting and investment planning.

Using the appropriate discount rate, computations are performed to determine the current value of a stream of future payments, or NPV. Projects that have a positive NPV are generally worthwhile pursuing, whereas those that have a negative NPV are not.

The current worth of a stream of payments from a business, project, or investment is determined using net present value (NPV).You must predict the timing and size of future cash flows in order to determine NPV, and you must choose a discount rate that is equal to the least allowable rate of return.Your cost of capital or the rewards offered by substitute investments with equivalent risk may be reflected in the discount rate.Positive NPV indicates that the rate of return on a project or investment will be higher than the discount rate.

Step-by-step explanation:

Given that,

8 + (n - 4)

According to Associative Property:

A + (B + C) = (A + B) + C

Using Associative property for the given expression.

We get:

(8 + n) - 4

[tex]\rule[225]{225}{2}[/tex]

The answer to this question is = 12 + n is the expression not equivalent to 8 + (n - 4)

Let us consider any random value of n for example let us take the value of n = 5

As per the original equation given in question 8 + (n - 4) if we substitute the value of n = 5

= 8+ (5 - 4)

= 8+1

= 9

Now we will be substituting the value of n in all the answer options-

Option 1- (8 - 4) + n

= (8 - 4) + 5

= 4 + 5

= 9

Therefore, this answer matches the original equation so this is not the correct option

Option 2- (8 + 4) - n

= (8 + 4) - 5

= 13 - 5

= 9

Therefore, this answer matches the original equation so this is not the correct option

Option 3- n+4

= 5 + 4

= 9

Therefore, this answer matches the original equation so this is not the correct option

Option 4- 12 + n

Find the present value of an annuity due that pays $4000 at the beginning of each quarter for the next 8 years. Assume that money is worth 5.4%, compounded quarterly. (Round your answer to the nearest cent.)

Answers

Present Value of Annuity = $4,000 × 26.1948  = $104779.2

What is a present value?

The worth of an anticipated revenue stream assessed as of the valuation date is known as the present value in the fields of economics and finance.

Here, we have

Where , Annuity Amount = $4,000            

n = No. of periods = 8 years × 4 quarters per year = 32 periods but since the first payment is at beginning of the quarter,

Then, n = 31 when considered for PVAF

r  = 5.4% / 4 quarters = 1.35%,

Present value of Annuity  = Annuity Amount × Present Value Annuity Factor i.e. PVAF (n, r)

PVAF(n₀,r) when the first payment is at beginning of n i.e.

n₀ = 1 + { [1-(1+r)^ -n ]/r }

= 1 + { [1-(1+0.0135)^ {-31}]/0.0135 }

= 1 + [ (1 - 0.65987 ) ] / 0.0135]

= 1 + 25.1948

= 26.1948

PVAF(32,35%) = 26.1948

Hence, Present Value of Annuity = $4,000 × 26.1948  = $104779.2

Find the amount A in an account (to the nearest cent) after 10 years if

dA
dt = rA, A(0) = 15,000 and A(8) = $22,377.37

Answers

The amount A in an account to the nearest cent, the amount A in the account after 10 years is $30,441.65.

What is the amount A in an account?

Generally, To find the amount A in the account after 10 years, we can use the formula for continuous compound interest:

A(t) = A(0) * e^(rt)

where A(t) is the amount in the account after t years, A(0) is the initial amount in the account, r is the interest rate, and t is the number of years.

In this case, we know that A(0) = $15,000, A(8) = $22,377.37, and t = 10 years. We can rearrange the formula to solve for r:

r = (1/t) * ln(A(t)/A(0))

Substituting the known values, we get:

r = (1/10) * ln(22377.37/15000)

Solving this equation, we get r = 0.0658082.

Now that we have the value of r, we can use the formula for continuous compound interest to find the amount A in the account after 10 years:

A(10) = 15000 * e^(0.0658082 * 10)

Solving this equation, we get A(10) = $30,441.65.

a quadratic function f is given by f(c) = ax^2+bx+c where a is not 0

Answers

The roots of a quadratic function are the values of x that make the function is 0. These roots can be found by solving the equation f(x) is 0.

What is quadratic function ?

A quadratic function is a type of mathematical function that can be written in the form f(x) = ax^2 + bx + c, where a, b, and c are constants and a is not equal to 0. This type of function is called a quadratic function because the highest power of x in the function is 2.

The graph of a quadratic function is a parabola, which is a U-shaped curve. The shape of the parabola is determined by the value of the constant a. If a is positive, the parabola opens upwards and if a is negative, the parabola opens downwards.

The roots of a quadratic function are the values of x that make the function equal to 0. These roots can be found by solving the equation f(x) = 0. To solve this equation, we can use the quadratic formula, which is:

x = (-b +/- sqrt(b^2 - 4ac)) / (2a)

What is the equation of the line that is normal to the curve y^2+Inx=19 at the point (e^3,-4)

Answers

The equation of the line that is normal to the curve y² + ln(x) = 19 at the point (e³, -4) is given as follows:

y + 4 = -8e³(x - e³).

How to obtain the equation of the line normal to the curve?

The equation of the line normal to a curve follows the point-slope definition of a linear function, given as follows:

y - y' = m(x - x').

The derivative of the function is found applying implicit differentiation, as follows:

2y dy/dx + 1/x = 0

dy/dx = -1/(2xy).

At x = e³, y = -4, the numeric value of the derivative is given as follows:

dy/dx = e^(-3)/8.

The normal line is perpendicular to the tangent line, hence it's slope is calculated as follows:

m x e^(-3)/8 = -1.

m = -8e³.

Then the equation of the line normal to the curve at the point is given as follows:

y + 4 = -8e³(x - e³).

Question 21 of 25
What is the length of the x-component of the vector shown below?
8
71°
OA. 2.6
OB. 8.0
OC. 7.6
OD. 5.2

Answers

To find the length of the x-component of the vector, we need to use trigonometry. The x-component is the adjacent side of the right triangle formed by the vector, and the length of the vector is the hypotenuse.
Using the Pythagorean theorem, we can find the length of the x-component:
x^2 = 8^2 - 7.1^2
x = sqrt(64 - 50.41)
x = sqrt(13.59)
x = OD. 5.2

Therefore, the length of the x-component is 5.2.
