point A bisects LS BC. If LS BA=6x-3 and LS AC= 3x+7. Solve for X. PLS ANSWER QUICKLY!!!

Answers

Based on the bisection of line BC by point A, the value of x is 10/3

How to determine the value of x?

The given parameters are:

Point A bisects BCBA = 6x - 3 AC= 3x + 7

Because the point A bisects BC, then

BA = AC

Substitute the known values in the above equation

So, we have

6x - 3 = 3x + 7

Collect the like terms

6x - 3x = 3 + 7

Evaluate the like terms

3x = 10

Divide both sides of the equation by 3

x = 10/3

Hence, based on the bisection of line BC by point A, the value of x is 10/3

A circle is a locus (collection) of points that are a defined distance apart from one another. The fixed point and fixed distance are referred to as the "center" and "radius," respectively. A quarter-circle is one-quarter of a circle. As a result, the area of a quarter circle is one-fourth of the size of a full circle.

A quarter circle is the area (or part) created by two perpendicular radii and one-fourth of the circumference of a circle. This is also known as a circular quadrant. For example, if a circle is divided into four equal pieces, each half is a quarter circle (or) a quadrant.

Can sides of a triangle have the lengths of 5 mm., 10 mm., and 15 mm.? *
OYes
O No

Answers

No, The sum of the lengths of any two sides of a triangle must be greater than the length of the third side according to Pythagorean theorem.

What is the Pythagorean theorem?

The Pythagorean Theorem states that the squares on the hypotenuse (the side across from the right angle) of a right triangle, or, in standard algebraic notation, a2 + b2, are equal to the squares on the legs.

a right triangle needs to follow the Pythagorean theorem, that is,

a2 + b2 = c2

where c is the length of the hypotenuse and a and b are the lengths of the other sides of the right triangle.  We can check to see if this property holds for the given triangle.  Since

5² + 10² = 15²

25 + 100 = 225

the Pythagorean theorem does not hold for the given triangle, meaning that it can not be a right triangle.

including tax, allie pays $8652.60 for a used car, if the price before tax was $8280, what is the tax rate where allie lives

Answers

Answer:

4.49% (rounded to 2 decimal places)

Step-by-step explanation:

Let the tax rate be r%

The tax paid on car = (Final Sale Price) - (Before Tax Price)

= 8652.60 - 8280 =  $372

Tax rate as a decimal = Tax/(Before Tax Price)

= 372/8652.60 ≈ 0.0449275  (rounded to 7 decimal places)

To find tax rate as percentage multiply the above by 100 to get tax rate as
0.0449 x 100 ≈ 4.49275% ≈ 4.49% (rounded to 2 decimal places)

f has a range of (-infinaty, 7),
and a graph that is symmetric
about the line x = 3, and has a
Y-intercept of 4

Answers

Answer:

[tex]f(x)=-|x-3|+7[/tex]

Step-by-step explanation:

The parent function of an absolute function is the modulus function:

[tex]f(x)=|x|[/tex]

Graph of Modulus function:

(see 2nd attachment)

[tex]f(x)=|x|=\begin{cases} \textsf{\:\:\:$x$, \quad if $x\geq 0$}\\\textsf{$-x$, \quad if $ x < 0$} \end{cases}[/tex]

Its vertex is at the origin (0, 0).

Its line of symmetry is x = 0.

It opens upwards.

Given information:

Range:  (-∞, 7)Axis of symmetry: x = 3y-intercept:  (0, 4)

The axis of symmetry is the x-value of the vertex of an absolute function. 

The y-value of the range is the y-value of the vertex of an absolute function.  

Therefore, the vertex of the absolute function f(x) is (3, 7).

Graphing

Plot the vertex at (3, 7) and the y-intercept at (0, 4).As the function f(x) has a range of (-∞, 7), it opens downwards.  Draw a straight line through the y-intercept that terminates at the vertex.Draw a line that is symmetrical to this line.

To find the equation of the absolute function, work out the series of transformations that take the parent function to the given function.

As the function f(x) has a range of (-∞, 7), it opens downwards.  Therefore, the parent function has been reflected in the x-axis:

[tex]\implies -f(x)=-|x|[/tex]

As the function f(x) is symmetric about the line x=3, the parent function has been translated 3 units to the right:

[tex]\implies -f(x-3)=-|x-3|[/tex]

Finally, as the highest y-value of the function is y = 7, the y-value of its vertex is y = 7.  Therefore, the parent function has been translated 7 units up:

[tex]\implies -f(x-3)+7=-|x-3|+7[/tex]

Therefore, the equation of the absolute function with the given parameters is:

[tex]f(x)=-|x-3|+7[/tex]

Given:

Function composition is an operation that takes two functions and produces a third function.

The composite function (g o f)(x) means to substitute the function f(x) in place of the x in function g(x).

[tex]\begin{aligned} \implies (g \circ f)(x) & = g\left[f(x)\right]\\& = g(-x+7)\\& = (-x+7)^2-4(-x+7)+4\\& = (-x+7)(-x+7)+4x-28+4\\& = x^2-14x+49+4x-28+4\\& = x^2-14x+4x+49-28+4\\& = x^2-10x+25\end{aligned}[/tex]

Answer:

x² - 10x + 25

Step-by-step explanation:

The given information is,

The equation we form is,

→ (gof)(x)

→ g[f(x)]

→ f(x)² - 4f(x) + 4

Let's solve the problem,

→ f(x)² - 4f(x) + 4

→ (-x + 7)² - 4(-x + 7) + 4

→ x² - 14x + 49 + 4x - 28 + 4

The product of the given equation for the fourth root is 7.

What is defined as the 4th root?

The 4th root of an amount is the number that, when multiplied four times by itself, yields the original number.

In other words, the square root of the square root of the square root of the square root of the square root of the square root of the square root of the square root of the square root of the square root of the square root. In addition, the fourth root is demonstrates the idea by multiplying the radical by 4, i.e. 4√.A number that is a square root of 4 has a result of 4 when multiplied by itself. There are two numbers which will work: 2×2=4 and −2×−2=4 which means that the numbers 2 and 2 are square roots of 4.

For, the given question;

= ⁴√7 × ⁴√7 × ⁴√7 × ⁴√7

This equation can be written as;

=(⁴√7)⁴

Further writing the fourth root in terms of fraction;

= (7)∧(1/4)×4

Both power will cancel each other.

= 7

Therefore, the product of the fourth root is found as 7.

Emma is training for a 10-kilometer race. She wants to beat her last 10-kilometer time, which was 1 hour 10 minutes. Emma has already run for 55 minutes. Which inequality can be used to find how much longer she can run and still beat her previous time? (1 hr = 60 min)

Answers

The time Emma should take for the run must be less than 15 minutes to bear her previous record.

What is referred as the inequality?The expression 5x - 4 > 2x + 3 resembles an equation, but the equals sign has been replaced through an arrowhead. It's an example of inequity. This means that the left part, 5x - 4, is larger than the right part, 2x + 3. We'll be looking for x values where the inequality holds true.

Emma's previous record was 1 hour and 10 minutes. This is equivalent to

60+10 minutes equals 70 minutes.

She already has run 55 minutes;

So, let us consider the remaining time, x, added to 55, must be less than 70 to overcome her previous time:

x + 55 < 70

The inequality is obtained.

Subtract 55 from each side:

x + 55-5 < 70-55

x < 15
