Answer:

the answer is A.616.39

Step-by-step explanation:

Megan can withdraw $615.21 per month for 5 years from the new account.

Option B is the correct answer.

An equation contains one or more terms with variables connected by an equal sign.

Example:

2x + 4y = 9 is an equation.

2x = 8 is an equation.

We have,

To solve this problem, we need to use the formula for the future value of an annuity:

[tex]FV = P [(1 + r/n)^{n\times t} - 1]/(r/n)[/tex]

where:

P = payment per period

r = interest rate per period

n = number of compounding periods per year

t = number of years

FV = future value of the annuity

First, we can calculate the future value of Megan's semiannual payments after 10 years:

P = $1,624.13

r = 1.5%/2 = 0.0075 (semiannual interest rate)

n = 2 (semiannual compounding periods)

t = 10 years

So,

[tex]FV = 1,624.13 \times[(1 + 0.0075/2)^{2\times10} - 1]/(0.0075/2)[/tex]

= $21,070.58

Next, we need to calculate the future value of this amount when transferred to the new account:

r = 2.3% / 12 = 0.00191667 (monthly interest rate)

n = 12 (monthly compounding periods)

t = 5 years (60 months)

FV

[tex]= $21,070.58 \times (1 + 0.00191667)^{60}[/tex]

= $24,526.41

Finally, we need to calculate the monthly payment Megan can withdraw for 5 years from this account, assuming the balance is depleted at the end of the 5 years:

P = ?

r = 2.3% / 12 = 0.00191667 (monthly interest rate)

n = 12 (monthly compounding periods)

t = 5 years (60 months)

Using the formula for the present value of an annuity:

[tex]P = FV \times (r/n) / [(1 + r/n)^{n\timest} - 1][/tex]

[tex]= $24,526.41 \times (0.00191667) / [(1 + 0.00191667)^{60} - 1][/tex]

= $615.21

Therefore,

Megan can withdraw $615.21 per month for 5 years from the new account.

To achieve 204 gallons of 5% butterfat milk, one would need 136 gallons of 6% butterfat milk and 68 gallons of 3% butterfat milk by solving a system of linear equations.

How to Mix Butterfat Percentages for Milk

To solve the problem of mixing two different butterfat percentages of milk to achieve a certain amount of milk with a desired fat content, we will use a system of equations.

Let x represent the gallons of 6% butterfat milk, and y represent the gallons of 3% butterfat milk.

To achieve 204 gallons of 5% butterfat milk, we have the following equations:

Equation 1: x + y = 204 (total gallons of milk)

Equation 2: 0.06x + 0.03y = 0.05(204) (total butterfat content)

Solving these equations simultaneously, we find:

From equation 1, we can express y as y = 204 - x.

Substituting this into equation 2 gives us 0.06x + 0.03(204 - x) = 10.2.

Simplifying this, we get 0.06x + 6.12 - 0.03x = 10.2, which leads to 0.03x = 4.08.

Hence, x = 136 gallons of 6% butterfat milk and y = 68 gallons of 3% butterfat milk.

Answer:

If KE = OS then we can deduce that the trapezoid is constructed of 3 equilateral triangles and thus we can easily work out the angles.

OSK = 60

SKE = 120

KEP = 120

EPO  = 60

We can also easily work out the perimeter since we can deduce that PE = SK = KE and thus the perimeter is 5 * 8 = 40

The measure of ∠S, ∠K, ∠E, and ∠P is 60°, 120°, 120°, and 60°, respectively.  While the perimeter of EPSK is 40 units.

A trapezoid is a quadrilateral which is having a pair of opposite sides as parallel and the length of the parallel sides is not equal.

Given KE=OS=8, but OS is the radius of the circle, therefore, it can be written as,

OS = OP = KE = OK = OE = radius of the circle = 8 units.

Since in ΔOEK all sides are equal it is an equilateral triangle therefore, the measure of the angle ∠EOK is 60°.

As the measure of the angle, ∠EOK is 60°, the measure of the angle, ∠KOS and ∠EOP will be 60° each.

Also, in ΔSOK and ΔPOE, the sides OS = OP = KE = OK = OE are equal, they are equilateral triangles as well.

Therefore, the measure of ∠KSO and ∠EPO will be 60° each.

The angles at the end of the non-parallel sides of a trapezium are supplementary. Therefore, we can write,

∠KSO + ∠SKE= 180°

∠SKE = 120°

Similarly, the measure of the ∠PEK is 120°.

Further, it is known that the measure of the sides OS=OP=PE=EK=KS = 8 units, therefore, the perimeter of the trapezium is,

Perimeter = OS + OP + PE + EK + KS = 8+8+8+8+8 = 40 units.

Hence, the measure of ∠S, ∠K, ∠E, and ∠P is 60°, 120°, 120°, and 60°, respectively.  While the perimeter of EPSK is 40 units.

Final answer:

The rational expression[tex](r^2 - 4r + 5)/(r - 4)[/tex] is already in its simplest form, as the numerator cannot be factored to cancel out any terms with the denominator.

Explanation:

The question asks for the simplified rational expression for the quadratic equation [tex]r2 - 4r + 5[/tex] divided by the linear expression r - 4. Simplifying rational expressions often involves factoring the numerator and the denominator and then canceling out common factors. However, in this case, the numerator cannot be factored in a way that will cancel out terms with the denominator. Simplifying further requires either polynomial division or realization that the expression is already in its simplest form because there are no common factors. Therefore, the rational expression[tex]r2 - 4r + 5[/tex] over r - 4 is already simplified as no further reduction is possible.

Answer:

Step-by-step explanation:

The average rate of change of f(x) in the closed interval [ a, b ] is

[tex]\frac{f(b)-f(a)}{b-a}[/tex]

here [ a, b ] = [ 1, 5 ]

f(b) = f(5) = 3 × 5² = 75

f(a) = f(1) = 3 × 1² = 3, hence

average rate of change = [tex]\frac{75-3}{5-1}[/tex] = [tex]\frac{72}{4}[/tex] = 18

Answer:18

Step-by-step explanation:

here [ a, b ] = [ 1, 5 ]

f(b) = f(5) = 3 × 5² = 75

f(a) = f(1) = 3 × 1² = 3, hence

average rate of change =  =  = 18

For this case we have that by definition of trigonometric relations that, the sine of an angle is equal to the opposite leg to the angle on the hypotenuse. So:

[tex]Sin (36) = \frac {5} {x}[/tex]

Clearing x:

[tex]x = \frac {5} {sin (36)}\\x =\frac {5} {0.58778525}\\x = 8.517887564 [/tex]

Option D

No. You cannot use the Pythagorean theorem to find the missing side, because you can only use The Pythagorean theorem when you are dealing with a right triangle.

To find the slope, you should rearrange the equation into slope-intercept form, ie. y = mx + c, where m is the gradient.

y - 9 = 15(x - 5)

y = 15(x - 5) + 9 (Add 9 to each side)

y = 15x - 15*5 + 9 (Expand 15(x - 5))

y = 15x - 75 + 9

y = 15x - 66

Therefor, the slope of the equation is 15.

sin 40/x =sin 60/12

Step-by-step explanation:

The question is on law of sines

Given a triangle with sides a, b, c and angles A, B, C respectively, the sine law states that; a/sin A = b/sin B = c/sin C

In the question x=a, b=12 feet, A=40° , B=60° and C=80°

Finding value of x;

x/sin 40° = 12/sin 60°

x sin 60° =12 sin 40°

x=12 sin 40 / sin 60

x=29.33 ft

Answer:

The length of the pole is 9.90 feet.

Step-by-step explanation:

From the figure, it is given that x is the length of the pole and the pole casts a shadow when the sun is at 40 degree angle.

Thus, using the sine law, we have

[tex]\frac{a}{sinA}=\frac{b}{sinB}=\frac{c}{sinC}[/tex]

Substituting the given values, we get

[tex]\frac{x}{sin40^{\circ}}=\frac{12}{sin60^{\circ}}=\frac{c}{sin80^{\circ}}[/tex]

Taking the first two equalities, we have

[tex]\frac{x}{sin40^{\circ}}=\frac{12}{sin60^{\circ}}[/tex]

[tex]x=\frac{12sin40^{\circ}}{sin60^{\circ}}[/tex]

[tex]x=\frac{12{\times}0.642}{0.866}[/tex]

[tex]x=8.90 feet[/tex]

Therefore, the length of the pole is 9.90 feet.

divide both sides by 2

simplify

The graph of the system of equations solves the equation -1/3x + 3 = x - 1.

The first step in solving a system of equations is to isolate one variable in one of the equations. We can begin by rearranging the first equation -1/3x + 3 = x - 1 to isolate x. First, multiply both sides of the equation by 3 to get rid of the fraction: -x + 9 = 3x - 3. Then, add x to both sides to bring all the x terms to one side: 9 = 4x - 3. Finally, add 3 to both sides to solve for x: 12 = 4x. Dividing both sides by 4 gives us x = 3.

Substitute this value of x into either of the original equations to solve for y. Let's use the second equation: (1/3)(3) - 3 = -3 + 1. Simplifying this equation, we get 1 - 3 = -2. This tells us that y = -2.

Therefore, the solution to the system of equations is x = 3 and y = -2, and it satisfies the equation -1/3x + 3 = x - 1.

The statements about the functions that are true include:

A. f(x) and g(x) intersect at exactly two points.

B. The x-intercepts of f(x) are common to g(x).

In Mathematics and Geometry, the x-intercept of any function is the point at which the graph of a function crosses or touches the x-axis and the y-value or value of "y" is equal to zero (0).

By critically observing the table of values and graph shown in the image attached above, we can reasonably and logically deduce the following x-intercepts for both f(x) and g(x):

x-intercepts of f(x) = (-1, 0) and (1, 0).

x-intercepts of g(x) = (-1, 0) and (1, 0).

Therefore, the x-intercepts of f(x) are common to g(x), which means they intersect at exactly two points.

For the minimum value of f(x) and g(x), we have;

Minimum value of f(x) = -1

Minimum value of g(x) = -3

Therefore, the minimum value of f(x) is greater than the minimum value of g(x).

For the y-intercept of f(x) and g(x), we have;

y-intercept of f(x) = (0, -1).

x-intercepts of g(x) = (0, 1).

In conclusion, we can logically deduce that f(x) and g(x) have different y-intercept.

For this case we must find the value of "b" of the following equation:

[tex]\frac {3} {2} + b = \frac {7} {4}[/tex]

[tex]\frac {3} {2} - \frac {3} {2} + b = \frac {7} {4} - \frac {3} {2}\\b = \frac {7} {4} - \frac {3} {2}\\b = \frac {14-12} {8}\\b = \frac {2} {8}\\b=\frac{1}{4}[/tex]

Object from Catapult B

Step-by-step explanation:

The question is on time of flight in falling objects

Given catapult A: h(x)= -16x^2+64x+17, find the height the object will reach at time 2.0

substitute value x=2 in h(x)= -16x^2+64x+17;

h(2)= -16 × (2)² +64 ×2 +17

h(2) = -16×4 + 145

h(2)= 81

However with catapult B at t=2.0 the height reached will be 60

Solution

Catapult A object will attain h=81, when t=2.0

Catapult B object will attain h=60, when t=2.0

Thus Object from Catapult B will hit the ground first because it covered a lesser distance compared to the object from catapult A
