4) Doing two distance formulas to show that adjacent sides are not the same length.

Step-by-step explanation:

Parallelogram is a quadrilateral which has opposite sides equals and parallel. Example of a parallelogram are rhombus, rectangle, square etc.

We can prove that a quadrilateral MNOP is a parallelogram. If we find the slopes of all four sides and compare those of the opposite ends, same slopes would indicate the opposite sides are parallel, hence the quarilateral is a parallelogram. We can also find the distance of two opposing sides, and slopes of twp opposing sides to determine whether it is a parallelogram or not. The most difficult approach is that diagonals bisect each other at same point.

However, using only two distance formulas will not give us enough information to determine whether a side is parallel or not.

Step-by-step explanation:

We start by finding the actual algebraic expression for g(x):

g(x) = f(x+1) = 4(x+1) - 2 = 4 x + 4 - 2 = 4 x + 2

Then we plot this function on the x-y plane using two or three pairs solution to the equation, like:

for  x = 0  g(x) = 2

for x = 1   g(x) = 6

for x = -1  g(x) = -2

and joining them with a line.

Answer:

a) 8 seconds

b) 3 seconds

c) 170 meters

Step-by-step explanation:

a) When the ball lands in the sea, s = -80.

-80 = 30t − 5t²

5t² − 30t − 80 = 0

t² − 6t − 16 = 0

(t + 2) (t − 8) = 0

t = -2 or 8

t = 8 seconds

b) The ball reaches its highest point when the velocity is 0 (or at the vertex of the parabola).

t = -b / (2a)

t = -30 / (2 × -5)

t = 3 seconds

c) The highest point is:

s = 30(3) − 5(3)²

s = 45

So the ball rises 45 meters, falls 45 meters, then falls 80 meters.

The total distance traveled is 45 + 45 + 80 = 170 meters.

B. x = 3

Step-by-step explanation:

You really don't need to quadratic formula for this. It would take too much time. Instead, factor out the equation:

(x -3)(x - 3) = 0

Once you found that, you should see that your roots will equal to 3.

Answer:

solution,

Rewrite x^2-6x+9 in the form a^2-2ab+b^2 where a=X and b=3.

[tex] {x}^{2} - 2(x)(3) + {3}^{2} = 0[/tex]

Use square of difference,

[tex] {(a - b)}^{2} = {a}^{2} - 2ab + {b}^{2} \\ {(x - 3)}^{2} = 0[/tex]

Take the square root of both sides

[tex]x - 3 = 0[/tex]

Add 2 to both sides,

[tex]x - 3 + 3 = 0 + 3 \\ x = 3[/tex]

hope this helps..

Answer: 60 dogs are male and over 3 years out of total 150 male dogs.

Step-by-step explanation:

Total no. of dogs are 500

Males are 500 x 0.3 = 150

Over 3 years are 150 x 2/5 = 60

Answer:

Total number of dogs:  500

Percent that is male: 30

Over the age of 3: 2/ 5

30 % of 500 = 150

MAKE IT INTO A FRACTION

2=  60

5  = 150

60 of the dogs are male and over 3 years.

Answer:

3 (x - 5.50) = 111.75

Step-by-step explanation:

They paid $111.75 for three months,  that means they minus $5.50 every month which means a total of $16.5 for three months.

So you need use $111.75 plus the credit $16.5 for three months

111.75 + 16.5 = 128.25

Then use divide them by 3, (three months)

128.25 / 3 = 42.75

So they pay $42.75 per month before the credit.

Answer: B

Step-by-step explanation:

-3x^2-9xi+9ix-27

-3x^2-27

The equivalent expression is (-3x+ 9i)(x+ 3i).

Mathematical statements are called expressions if they have at least two terms that are related by an operator and contain either numbers, variables, or both. Addition, subtraction, multiplication, and division are all possible mathematical operations.

A mathematical expression is a phrase that has a minimum of two numbers or variables and at least one mathematical operation.

Given:

-3x² - 27

First, (-3x - 9i)(x+ 3i)

= -3x² - 9ix - 9ix -27i²

= -3x² -18i + 27

Second, (-3x+ 9i)(x+ 3i)

= -3x² -9xi + 9ix + 27i²

= -3x² - 27

Third, (-3x+ 3i)( x+ 9i)

= -3x² -27ix + 3ix + 27i²

=-3x² -24ix - 27

Fourth, (-3x - 3i)( x- 9i)

= -3x² - 27ix - 3ix -27i²

= -3x² - 30ix + 27

Hence, the equivalent expression is (-3x+ 9i)(x+ 3i).

Answer:

The area of the rectangle would be 20 square units.

Step-by-step explanation:

The distance between the points (-8, -2) and (-3,-2) is 5. This is the length of the rectangle.  The distance between (-3,-6) and (-3,-2) is 4. This is the width of the rectangle. To find the area, multiply the length and the width to get the 20 square units as the area.

Answer:

Area = 20

As B = -4

Where -3-1 = -4

We look at x for first measure = -8 -3 = 5

We look at y first sequence change for second measure = -B

x/y = -3-8 /-8 + B

= -3-8 = -8(-8)+B

B = -3+B = -3+1

B= -3+1 = -4

Second measure = -8-4 = 4

Therefore, using both measures in bold : the Area = 4 x 5  = 20

Answer:

[tex]A = 20,000(0.85)^t[/tex]

Step-by-step explanation:

We will use the formula for compound interest here

where [tex]A = p( 1 + r)^t[/tex]

   A=future value  for any sum

   P=present value of the sum

   r= yearly interest rate, it should be expressed in  decimal

   t=time period , it should be in years

______________________________

given in the problem

p = $20,000

r = 15% (in decimal 15/100 = 0.15)

t is the time for which equation is to be model to find future value p

since, rate is for depreciation we need to take negative value of rate as value for computer will decrease

thus

r = -0.15

using the above values in formula  [tex]A = p( 1 + r)^t[/tex]

[tex]A = p( 1 + r)^t\\A = 20,000(1 - 0.15)^t\\A = 20,000(0.85)^t[/tex]

Thus, model  equation for the value of the computer is [tex]A = 20,000(0.85)^t[/tex]
