Answer:

(i) Not true for any cases, (ii) True for some cases, (iii) True for some cases, (iv) True for all cases.

Step-by-step explanation:

Now we proceed to check each statement in terms of concepts of function from Analytical Geometry:

(i) Two lines that have the same y-intercept and the same slope intersect at exactly one point.

False, two lines that have the same y-intercept and the same slope intersect at every point. Both lines are coincident. (Answer: Not true for any cases)

(ii) Two lines that have the same y-intercept intersect at exactly one point.

Conditionally true, two lines that have the same y-intercept intersect at exactly one point if and only if slopes are different. (Answer: True for some cases)

(iii) Two lines that have the same slope do not intersect at any point.

Conditionally true, two lines that have the same slope do not intersect at any point if and only if they share the same y-intercept. (Answer: True for some cases)

(iv) Two lines that have two different slopes intersects at exactly one point.

True, two lines that have two different slopes intersects at exactly one point no matter what y-intercepts they have. (Answer: True for all cases)

Answer:

Reference Point

Step-by-step explanation:

The answer is reference point. This is because reference point is used to determine if an object is in motion or if it has changed is direction.

Thus, reference point has to be a value of zero for us to use it to determine if an object has moved.

x2=36

We move all terms to the left:

x2-(36)=0

We add all the numbers together, and all the variables

x^2-36=0

a = 1; b = 0; c = -36;

Δ = b2-4ac

Δ = 02-4·1·(-36)

Δ = 144

The delta value is higher than zero, so the equation has two solutions

We use following formulas to calculate our solutions:

x1=−b−Δ√2ax2=−b+Δ√2a

Δ‾‾√=144‾‾‾‾√=12

x1=−b−Δ√2a=−(0)−122∗1=−122=−6

x2=−b+Δ√2a=−(0)+122∗1=122=6

Answer:

  x = -6 or +6

Step-by-step explanation:

You know from your multiplication tables that 6×6 = 36, so one answer is ...

  x = 6

You also know that the product of two negative numbers is positive, so another answer is ...

  x = -6

__

Check

  x² = 6² = 6×6 = 36

  x² = (-6)² = (-6)×(-6) = 36

_____

Alternate approach

If you like, you can rewrite the equation as ...

  x² -36 = 0

This can be factored to ...

  (x -6)(x +6) = 0

The zero product rule tells you this product will only be zero if one or the other factors is zero.

  x -6 = 0   ⇒   x = 6

  x +6 = 0   ⇒   x = -6

The two solutions are x = ±6.

Answer:

look I have sent you the answer of your question.

This trinomial can be factored as two binomials.

So setup two sets of parenthses.

8x² can be factored as 8x · x or 4x · 2x

and -3 can be factored as +3 · -1, -1· +3, -3 · +1, or +1 ·-3.

If the middle term in the original trinomial is even,

try pairs of even factors first if you have that option.

In this case, we have a 4x and a 2x so let's try those first.

Let's do this with all the factors of -3.

So our first possible answer could be (4x + 3)(2x - 1).

Since the product of the outer terms, -4x, plus the product of the inner, 6x,

doesn't add to our middle term, this pair doesn't work.

Now let's try (4x - 1)(2x + 3).

The product of the outer terms, 12x, plus the product of the inner, -2x,

equals the middle term in our original trinomial, this pair works.

So our answer is (4x - 1)(2x + 3).

Answer: 18 units long

Step-by-step explanation:

In the diagram, it looks like line segment AW is 6 units long and WB is 12 units long. Because of parts-whole postulate (the whole is equal to the sum of its parts), you can add AW and WB's lengths together. 6 + 12 = 18, so the length of line segment AB is 18 units long.

The Volume of green house is 54 m³

A rectangular prism is a three-dimensional shape that has two at the top and bottom and four are lateral faces.

The volume of a rectangular prism=Length X Width X Height

A company makes a greenhouse that is shaped like a rectangular prism on bottom and a half cylinder on top.

Given;

Base = 3m x 9m

Height of house = 2 m

Find: Volume of green house

Volume of green house = 3m x 9m x 2m

Volume of green house = 54 m³

Therefore, the Volume of green house is 54 m³

Answer:

76 feet (Just put 76 in the answer box)

Step-by-step explanation:

Knowing the perimeter of a rectangle is 2l + 2w, multiply 2 by 3.5. Then multiply 2 by 4.5, and add them together.

2(3.5) + 2(4.5)

The two products would be 7 and 9 respectively.

7 + 9 = 16 feet of fencing for 1 rabbit pen.

We have 2 pens, so multiply 16 by 2.

The rabbit pens need 32 feet of fencing.

(Alternatively you could have done 2(2(3.5 + 4.5)).

2(2(8))

2(16)

32 ft of fencing (rabbit pens))

Now, add 12 and 10. Then multiply that by 2.

2(12 + 10)

2(22)

The garden needs 44 feet of fencing.

Now add 32 and 44 to get the total amount of fencing needed.

32 + 44

The rabbit pens and the garden need 76 feet of fencing. (Just put 76 in the answer box as the unit (feet) is already given.)

Answer: D, 6km/hr.

Step-by-step explanation:

Heather can finish a 12-kilometer race in 2 hours, and now we have to find how many kilometers she can ride/run at in 1 hour.

How many hours can Heather run in 1 hour? To solve that, we can use the equation 12 ÷ 2.

12 ÷ 2 = 6.

Therefore, if Heather keeps her pace constant, then her rate will be 6km/hr, or D.

Answer:

It is A

Step-by-step explanation:

It starts from origin

The first graph represent the volume of water in a cylinder as a

function of its height.

a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.

The first graph with a straight line passing through the origin could represent the volume of water in a cylinder as a function of its height.

This is because the formula for the volume of a cylinder is V = πr²h, where r is the radius and h is the height.

If we keep the radius constant and vary the height, we can see that the volume of the cylinder increases linearly with the height. In other words, the volume is directly proportional to the height.

Since the line passes through the origin, this indicates that when the height is zero, the volume is also zero.

This is consistent with the fact that a cylinder with zero height has zero volume.

Hence, the first graph represent the volume of water in a cylinder as a

function of its height.
