Average = 1

Step-by-step explanation:

Let us define the average first:

Average is calculated by adding up all the values and then dividing the sum by total number of values.

The formula for average may be written as:

[tex]Average = \frac{Sum}{count}[/tex]

In the following case,

Sum of numbers = -3-2+2+2+6 = 5

Count = 5

So,

Average = 5/5

=> Average = 1

Answer:

the answer is 1

Step-by-step explanation:

Sum of numbers = -3-2+2+2+6 = 5

Count = 5

So,  

Average = 5/5

=> Average = 1

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.

Answer: The correct answer is 1/3x − 3 = −x + 1

Step-by-step explanation:

add 3 to both sides

simplify

add x to both sides

simplify

multiply both sides by 3

simplify

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.

Answer:

Step-by-step explanation:

Answer:

-3

Step-by-step explanation:

-2x+8=14

Subtract 8 from each side

-2x+8-8=14-8

-2x = 6

Divide by -2

-2x/-2 = 6/-2

x = -3

-2x + 8 = 14

Step 1: Bring 8 to the right side of the equation. To do this subtract 8 to both sides (this is the opposite of addition and will cancel 8 from the left side)

-2x + (8 - 8) = 14 - 8

-2x + 0 = 6

-2x = 6

Step 2: Isolate x by dividing -2 to both sides (division is the opposite of multiplication and will cancel -2 from the left side)

-2x/-2 = 6/-2

x = -3

Check:

Plug -3 where you see x and solve

-2(-3) + 8 = 14

6 + 8 = 14

14 = 14...............................Correct!

Answer:  56 mph

Step-by-step explanation:

48 miles x 2 hours = 96 miles

60 miles x 4 hours =  240 miles

240 + 96 = 360 total miles

360 / 6 (hours) = 56 mph

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.

Answer:

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

Speed is defined as quotient of distance and time.

[tex]

s=\frac{d}{t}=\frac{150}{18}=8.33\dots

Speed is a scalar value therefore we cannot determine its vector. Speed with vector is known as velocity and that is where we specify its vector because velocity is a vector value.

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.

Answer:

The approximate length of the diagonal of the rectangle = 6.4 units ⇒ B

Step-by-step explanation:

* Lets revise the properties of the rectangle

- The rectangle has 4 sides

- Each two opposite sides are parallel and equal in length

- It has for right angles

- Its two diagonals are equal in length

- The diagonal divide the rectangle into two congruent right triangles

* Now lets solve the problem

∵ The length of the rectangle = 5 units

∵ The width of the rectangle = 4 units

∵ The diagonal of the rectangle with the length and the width formed

  right triangle, the length and the width are its two legs and the

  diagonal is its hypotenuse

- To find the length of the hypotenuse use Pythagoras theorem

∵ Hypotenuse = √[(leg1)² + (leg2)²]

∴ The length of the diagonal = √[5² + 4²] = √[25 + 16] = √41

∴ The approximate length of the diagonal of the rectangle = 6.4 units

Answer:

Step-by-step explanation:

x^2 - 7x + 10 = 0 can be factored as follows:  (x - 5)(x - 2).  Note that -5x -2x combine to -7x, the middle term of this quadratic, and that (-5)(-2) = +10, the constant term.  Setting each of these factors = to 0 separately, we get:

x = 5 and x = 2.

x^2 - 2x = 20 should be rewritten in standard form for a quadratic equation before you attempt to solve it:  x^2 - 2x - 20 = 0.  This quadratic is not so easily factored as was the previous one.  Let's use the quadratic formula:

      -b ± √(b²-4ac)

x = --------------------

             2a

Here, a = 1, b = -2 and c = -20, so the discriminant b²-4ac = (-2)^2 - 4(1)(-20), or 4 + 80, or 84.  84 has only one perfect square factor:  4·21.  Because the discriminant is +, we know that this equation has two real, unequal roots.

They are:

       -(-2) ± √(4·21)         2 ± 2√21

x = ----------------------  =  ----------------- =   1 ± √21

Answer:

tan e = -1

cot e = -1

sin e = √2/2

cosec e = √2

cos e = -√2/2

sec e = -√2.

Step-by-step explanation:

6/6-  is the tangent of e  so tan e = -1.

cot e = 1/tan e = -1.

The hypotenuse  of the triangle containing angle e = √(-6)^2 + (6)^2 ( By the pythagoras theorem) and = √72 =  6√2.

Therefore sin e =   6/6√2

= 1/√2

= √2/2

cosec e  = 1 ./ sin e = √2.

cos e = -6 / 6√2

= -√2/2.

sec e = 1/cos e = -√2.
