Answers

Answer 1

The slope formula along with coordinates of points ( p,q) and (x,y) [tex]m = \dfrac{y-q}{x-p}[/tex].

What is the slope of a straight line?

A slope tells how vertical a line is.

The more the slope is, the more the line is vertical. When the slope is zero, the line is horizontal.

To find the slope, we take the ratio of how much the line's height increases as we go forward or backward on the horizontal axis.

This is because the more the height of the line to the amount we walk or run on the horizontal axis, the more the slope is.

The slope of a line that passes through points ( p,q) and (x,y)

Its slope would be:

[tex]m = \dfrac{y-q}{x-p}[/tex]

Slope of parallel lines are same. Slopes of perpendicular lines are negative reciprocal of each other.

Step-by-step explanation:

Base of the triangle (X) times height of triangle, divided by 2

-- Gage Millar, Algebra 1/2 Tutor (Pending Pre-Calc Tutor)

The area of the isosceles triangle will be A(x) = √15(x² / 4).

What is the triangle?

A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.

In an isosceles triangle, the two legs of the triangle are congruent and their opposite angles too.

The base of an isosceles triangle is half as long as each of the two equal sides.

Let the base length be x. Then the length of each other legs will be 2x.

A(x) = √[s(s - x)(s - 2x)(s - 2x)]

The value of s is half of the perimeter.

s = (x + 2x + 2x) / 2

s = 5x / 2

Then the area of the isosceles triangle will be

A(x) = √[5x / 2(5x / 2 - x)(5x / 2 - 2x)(5x / 2 - 2x)]

A(x) = √[5x / 2(3x / 2)(x / 2)(x / 2 )]

A(x) = √(15x⁴ / 16)

A(x) = (x² / 4)√15

The area of the isosceles triangle will be A(x) = √15(x² / 4).

How to identify coordinates of transformed triangles?

We are told that;

- Triangle XYZ is rotated 90º clockwise about the origin to form triangle X'Y'Z'.

- Thereafter, reflected across the x-axis to form triangle X''Y''Z''

Now, in transformation, Reflection is flipping an object across a line without changing its size or shape while Rotation is rotating an object about a fixed point without changing its size or shape. Thus, it means that the size and shape of the triangle formed is not different from the original one.

Thus, we can say that both triangles are congruent because the shape and size didn't change.

If the area of the region bounded by the curve y^2 =4ax and the line x= 4a is 256/3 Sq units, using integration find the value of a, where a > 0.

Answers

The value of a using integration is 2, such that the area of the region bounded by the curve y^2 =4ax and the line x= 4a is 256/3 Sq units

How to determine the value of a?

The given parameters are:

Curve, y² = 4ax

Line, x = 4a

Substitute x = 4a in y² = 4ax

y² = 4a * 4a

Take the square root of both sides

y = ±4a

This means that the point of intersection between the line and the curve is (4a, -4a) and (4a, 4a)

Remove the negative interval

So, we have: (4a, 0) and (4a, 4a)

The area is then calculated as

[tex]A =2 \int\limits^{4a}_0 {\sqrt y} \, dx[/tex]

This gives

[tex]A =2 \int\limits^{4a}_0 {\sqrt {4ax}} \, dx[/tex]

Remove the constant

[tex]A = 2\sqrt{4a}\int\limits^{4a}_0 {\sqrt {x}} \, dx[/tex]

Integrate

[tex]A = 2\sqrt{4a} * \frac 23 x^\frac32 |\limits^{4a}_0[/tex]

Evaluate the exponent

[tex]A = 4\sqrt{a} * \frac 23 x^\frac32 |\limits^{4a}_0[/tex]

Expand

[tex]A = 4\sqrt{a} * \frac 23 (4a)^\frac32[/tex]

Rewrite as:

[tex]A = 4 * a^\frac12 * \frac 23 * 4^\frac32 * a^\frac32[/tex]

Evaluate the exponents by the laws of indices

[tex]A = 4 * \frac 23 * 8 * a^2[/tex]

Recall that the area is:

A = 256/3

So, we have:

[tex]\frac{256}3 = 4 * \frac 23 * 8 * a^2[/tex]

Evaluate the quotients

[tex]256 = 4 * 2 * 8 * a^2[/tex]

Divide both sides by 64

4 = a²

Take the square root of both sides

2 = a

Rewrite as:

a = 2

Hence, the value of a is 2

Select the correct answer. If is modified as , what transformations will be seen in the graph? A. The graph will reflect across the x-axis and then shift units up. B. The graph will reflect across the y-axis and then shift units down. C. The graph will reflect across the x-axis and then shift units to left. D. The graph will reflect across the y-axis and then shift units to right.

Answers

The transformation is (b) The graph will reflect across the y-axis and then shift 5 units down.

How to determine the transformation?

The missing phrase in the question is: "If f(x) = 2ˣ + 1 is modified as g(x) = 2⁻ˣ + 1 - 5"

The functions are given as:

f(x) = 2ˣ + 1

g(x) = 2⁻ˣ + 1 - 5

First, the function f(x) is reflected across the y-axis (this eliminates options a and c)

The rule of this transformation is

(x,y) ⇒ (-x,y)

So, we have:

f'(x) = 2⁻ˣ + 1

Next, the function f(x) is shifted down by 5 units (this eliminates options d)

The rule of this transformation is

(x,y) ⇒ (x,y - 5)

So, we have:

f''(x) = 2⁻ˣ + 1 - 5

By comparing the functions f"(x) and g(x), we have:

g(x) = f''(x) = 2⁻ˣ + 1 - 5

Hence, the transformation is (b) The graph will reflect across the y-axis and then shift 5 units down.

the desired cases (not republican) out of all these 1920 possibilities are

Answers

Looking at the problem statement, the question is asking us to determine what the missing reasons are. The information that is given to us is a step-by-step process of solving an expression for an unknown. There are also two blanks in the reasons column for steps 3 and 5 which we will need to determine.

For step #3, we can see that they subtracted 6x from both sides which means that options 3 and 4 are automatically out since they reference addition in the first part. The correct reasoning for this part would be Subtraction Property of Equality which states that we subtract the same item from both sides of the expression.

We can see this being done in the following actions

[tex]4x - 8 = 6x + 18[/tex][tex](4x - 6x) - 8 = (6x - 6x) + 18[/tex][tex](4x - 6x) - 8 = 18[/tex][tex]-2x - 8 = 18[/tex]

For step #5, we can see that they divided both sides by -2 which means that option 1 is out since it references the multiplication property of equality. The correct reasoning for this part would be Division Property of Equality which states that we divide both sides by the same item.

We can see this being done in the following actions

[tex]-2x = 26[/tex][tex]\frac{-2x}{-2} = \frac{26}{-2}[/tex][tex]x= \frac{26}{-2}[/tex][tex]x= -13[/tex]

Therefore, the option that would best fit the description that we provided during our work would be option 2 (3. subtraction property of equality; 5. division property of equality).

Answer:

b) 3. addition property of equality; 5. division property of equality.

Step-by-step explanation:

Given: 4(x - 2) = 6x + 18

Prove: x = -13

Algebraic Properties:

Addition: If a = b, then a + c = b + cSubtraction: If a = b, then a - c = b - cMultiplication: If a = b, then ac = bcDivision: If a = b, then a ÷ c = b ÷ cDistributive: a(b + c) = ab + ac

Steps:

1. Given:

⟹ 4(x - 2) = 6x + 18

2. Distribute property:

4(x) + 4(-2) = 6x + 18 [distribute 4]

⟹ 4x - 8 = 6x + 18

3. Subtraction property of equality:

4x - 6x - 8 = 6x - 6x + 18 [subtract 6x from both sides]

⟹ -2x - 8 = 18

4. Addition property of equality:

-2x - 8 + 8 = 18 + 8 [add 8 to both sides]

⟹ -2x = 26

5. Division property of equality:

-2x ÷ -2 = 26 ÷ -2 [divide both sides by -2]

⟹ x = -13

In conclusion, the missing reasons are the subtraction and division properties of equality.

At a basketball game, 6% were supporting the visiting team. If total number of people attending the game was 2500, how many people were supporters of the home team?

Answers

There were 2350 people supporting the home team

How to determine the number of supporters?

The given parameters are:

Total = 2500

Proportion that supports the visiting team= 6%

Let the number of people that supports the team be x.

So, we have:

x = (1 - Proportion that supports the visiting team) * Total

This gives

x = (1 - 6%) * 2500

Evaluate

x = 2350

Hence, there were 2350 people supporting the home team
