Segment AB has endpoint A at (0,0). The midpoint of segment AB is located at (5,3). What are the coordinates of endpoint B? A. (10, 6) B. (6, 10) C. (2.5, 1.5) D. (1.5, 2.5)​

Answers

Answer 1

The coordinates of endpoint B is B( 10, 6).

What is coordinates?
A coordinate system in geometry is a method for determining the precise location of points or other geometrical objects on a manifold, such as Euclidean space, using one or more numbers, or coordinates. The coordinates' order is important, and often they are recognised by their place in an ordered tuple or by a letter, as in "the x-coordinate." In elementary mathematics, the coordinates are assumed to be real numbers, although they could instead be complex numbers or components of a more abstract system, such a commutative ring.

Let the coordinate at point B be B( x,y )

given that A(0,0) and the midpoint of the line AB is (5,3).

We know the mind point formula:

midpoint = ( x2 + x1 / 2 , y2 + y1 / 2)

Therefore according to the question,

B(5 = x + 0 / 2  ,  3 = y + 0 / 2)

B( 10, 6)

Find the difference in the latitudes of Athens, Greece, Latitude 38° N, and Sydney, Australia, latitude 34° S.

Answers

The difference in the latitudes of Athens, Greece, Latitude 38° N, and Sydney, Australia, latitude 34° S is 72° .

We have two different coordinates, 38° N and  34° S

We can find the differnce in two different coordinates by following a few steps.

We have to consider South as negative North. So, we can write 34° S as -34° N.

Hence, we can determine the difference in between two coordinates.

Difference in coordinates38° N - 34° S  = 38° N - ( - 34° N ) = 38° N + 34° N = 72°  N

So, we can conclude that, the difference is 72°.

Answers

Answer: Question E: The answer is that A(9) is greater.

Step-by-step explanation:

For questions A and C, you can see that the table is exponentially growing. So the equation will use multiplication. You can also see the value of the equation is growing by x2.

So you could say the table starts at a base of 1/2, then grows exponentially at a rate of 2. (Basically saying the value grows x2 per term). The equation will result in y= 1/2(2)^x

For questions B and D, you can see that the graph is growing linearly. So the equation will use multiplication.

By drawing a line between the lines you can easily see the growth of the triangle. You can then tell the 0th term to 1st term goes right 1 and up 10.

Next, you look at the 1st term to the 2nd term. You can tell that it goes right 1 and up 10. So, the rate is 10 per term. (10x) and it starts at 2 (+2). The equation will result in y=10x+2


Question E, solve each equation by substituting the x by 9.

A(9)

y= 1/2(2)^x

y= 1/2(2)^9

y= 1/2(512)

y=256

B(9)

y=10x+2

y= 10(9) +2

y= 90+2

y=92

The answer is that A(9) is greater.

The cost of a T-shirt is $15.95. Monica has a $5-off coupon that can be used for one T-shirt only. Write an algebraic expression for the cost of t T-shirts, not including sales tax.

Answers

The algebraic expression for the cost of t T-shirts, not including sales tax is  15.95t - 5.

Given that:-

Cost of a T-shirt = $ 15.95

Discount on coupon = $ 5 (can be used for one T-shirt only)

We have to write an algebraic expression for the cost of t T-shirts, not including sales tax.

We know that,

Total cost of T-shirts = (Number of T-shirts)*(Cost of one t-shirt) - Discount

Hence, we can write,

C(t) = t*(15.95) - 5

C(t) = 15.95t - 5

Where, C(t) is the cost of t T-shirts and t is the number of T-shirts.

If the distance from 0 to x on a number line is greater than 0, then -5 + x is positive?

True or false

Answers

False,
So let's say that x is 2.
The statement is:
-2 + x is positive
-2 + 2 is positive
O is positive
This is not correct

Let's say that x is-2
-2 + x is positive
-2 + (-2) is positive
-2-2 is positive
-4 is positive

True.

Given the statement 'If the distance from 0 to x on a number line is greater than 5, then -5+x is positive' is True.

For the given question,

The distance from 0 to x on a number line is greater than 5

We write the above statement in mathematical expression form as,

⇒ |x - 0| > 5

⇒ |x| > 5

⇒ x > 5  

We need to determine the value of an expression -5 + x

From (1),

⇒ x > 5  

Subtract -5 from both sides,

⇒ -5 + x = -5 + 5

⇒ -5 + x > 0

From the above expression, we observe that the value of the expression is always greater than 1.

This means the value of an expression -5 + x is positive.

Therefore, the given statement 'If the distance from 0 to x on a number line is greater than 5, then -5+x is positive' is True.

In mathematics, a number line can be described as a figure that symbolizes numbers on a consecutive line. The digits on a number line are positioned successively with equal spacing along its length. It can be infinitely expanded in any direction and is often depicted horizontally.

Absolute value is the distance between a digit and zero on a number line. Since the space is forever positive, the absolute value will always be positive.

Four ways to find the slope and y–intercept of straight line equation are;

Making use of the graph to find the slopeObtaining the coordinates of the x–intercept, Looking for the y–intercept when the slope and a point is knownSolving for the slope when two points are given

What is a straight line equation?

A straight line equation is of the form, y = m•x + c

Where;

m = The slope of the graph of the equation

c = The point the graph intersects the x–axis.

The process by which the slope–intercept form of a straight line equation can be found from the above ways are as follows;

1. Making use of the graph of the equation

When the graph is given, the y–intercept is found from the point the graph crosses the y–axis

Note the y–intercept

Find two points on the graph where coordinates can be obtained

Find the ratio of the rise to the run to get the slope of the graph

[tex] \displaystyle{ Slope, \: m = \frac{ rise}{run} } = \frac{ \triangle y }{\triangle x} [/tex]

With the slope and y–intercept, the equation of the line can be written as; y = m•x + c

2. Obtaining the coordinates of the x–intercept

Given the slope and the y–intercept, the x–intercept can be found by plugging in the values of the slope, m, and the y–intercept, c, in the equation, y = m•x + c, to get the equation of the line

From the equation, the x–intercept can be found by plugging y = 0, to get;

0 = m•x + c

The x–intercept becomes, [tex] \displaystyle \frac{-c}{m} [/tex]

The graph can then be plotted by drawing a line through the x and y–intercept

3. Finding the y–intercept given the slope and the x–intercept

When the slope and the x–intercept and the slope is known, whole number part of the numerator can be added to the x–value of the x–intercept to obtain the x–coordinates of a second point on the graph

The process is repeated to find the y–coordinate of the second point

The slope is calculated using the two points and the equation for the slope given in the first method

4. When two points are known, the slope is calculated using the equation in method 1

The two are joined with a straight line and the y–intercept is obtained from the point the graph intersects the y–axis
