[tex]25^{2x+1}=144[/tex] => x = 0.272, by properties of logarithm.

Given: [tex]25^{2x+1}=144[/tex]

Taking logarithm on both sides:

log ([tex]25^{2x+1}[/tex]) = log (144)

=> (2x + 1) log (25) = log (144) (As [tex]log_b(a)^m = m (log_b(a))[/tex])

=> 2x + 1 = [tex]\frac{log144}{log25}[/tex]

=> 2x + 1 = [tex]\frac{2.158}{1.397}[/tex]

=> 2x + 1 = 1.544

=> 2x = 0.544

=> x = 0.272

Hence, [tex]25^{2x+1}=144[/tex] => x = 0.272, by properties of logarithm.

The dimensions of the drawing of the rectangular plot using the scale of 1in.:5yd is; 24 inches by 10.6 inches

We are told that the dimensions of the rectangular plot of land is 120yd x 53yd.

Now, you want to draw this rectangular plot on a scale of 1 inch : 5 yards. This means that 1 inch will represent 5 yards.

Thus, for the side of 120 yards, using the scale gives us;

1/5 * 120 = 24 inches

For the side of 53 yards, using the scale gives us;

1/5 * 53 = 10.6 inches

Thus, the dimensions of the drawing of the rectangular plot using the scale of 1in.:5yd is; 24 inches by 10.6 inches

No extraneous solution to the equation.

The equation is

[tex](x + 5)^{1/2}[/tex] - [tex](5 - 2x)^{1/4}[/tex] = 0

To know whether the equation is an extraneous solution we first need to find the value of x.

So we have,

[tex](x + 5)^{1/2} = (5 - 2x)^{1/4}[/tex]

Multiply both sides with the power of 4, then we have

[tex]((x+ 5)^{1/2})^{4}[/tex] = [tex]((5 - 2x)^{1/4} )^{4}[/tex]

[tex](x+ 5)^{2}[/tex] = 5 - 2x

[tex]x^{2}[/tex] + 10x + 25 = 5-2x

[tex]x^{2}[/tex] + 12x + 20= 0

[tex]x^{2}[/tex] + 10x + 2x + 20 = 0

x(x + 10 ) + 2(x + 10) = 0

(x + 10)(x+2) = 0

x = -10, -2

Now we have to put the value of x in the equation

x = -10

[tex](-10 + 5 )^{1/2}[/tex]-[tex](5 - 2 * -10)^{1/4}[/tex] = 0

[tex](-5)^{1/2}[/tex] - [tex]25^{1/4}[/tex]= 0

[tex](-5)^{1/2}[/tex] - [tex]5^{1/2}[/tex] = 0

Which has not possible as we don't have negative number in the square root.

x = -2

[tex](-2 + 5)^{1/2}[/tex] -[tex](5-2*-2)^{1/4}[/tex]=0

[tex]3^{1/2}[/tex]- [tex]9^{1/4}[/tex]=0

[tex]3^{1/2}[/tex]- [tex]3^{1/2}[/tex]=0

0 = 0

We know that the measures of dispersion tend to see how numbers are scattered around the mean. In this case, we are asked to find three of the measures of dispersion which are; range, variance and standard deviation.

We first have to arrange the data in the proper order as follows;

20.1, 21.7, 23.2, 24.0, 30.9, 33.5, 58.4, 60.0, 74.8, 110.8

It is now easier for us to find the range of the data set as the difference between the largest and the smallest value; 110.8 – 20.1 = 90.7

The mean of the dataset is = 20.1 +  21.7+  23.2 + 24.0 + 30.9 + 33.5 + 58.4 + 60.0 + 74.8 + 110.8/10

= 45.74

Now;

Variance = (20.1 - 45.74)^2 + (21.7 - 45.74)^2 + (23.2 - 45.74)^2 + (24.0 - 45.74)^2 + (30.9 - 45.74)^2 + (33.5 - 45.74)^2 + (58.4 - 45.74)^2 + (60.0 - 45.74)^2 + (74.8 - 45.74)^2 + (110.8 - 45.74)^2/10

= 657.4 + 577.9 + 508.1 + 472.6 + 220.2 +149.8 + 160.3 + 203.3 + 844.5 + 4233/10

The linear function f(x) with a slope of -8 and that f(1) = 2 is f(x) = 10 -8x

From the question, we are find a linear function with slope of -8 and that f(1) = 2

If f(1) = 2, then the line passes through the point (1, 2)

Using the point-slope form of the equation of a straight line

y - y₁ = m(x - x₁)

Where m is the slope

Then,

y - 2 = -8(x - 1)

Simplify

y - 2 = -8x + 8

y = -8x + 8 + 2

y = -8x + 10

∴ f(x) = -8x + 10

f(x) = 10 - 8x

Answer: Emily's in total journey is 15.045 kilometers.

Step-by-step explanation:

Given data,

Emily traveled a certain distance on a horse = 10.98 kilometers

Emily traveled a certain distance on a bike = 4.06 kilometers

The overall distance traveled by Emily on her horse and bike needs to be determined.

For "Total Distance" , we will use addition operation:

So, Total distance covered by Emily's journey is given by equal to

Emily traveled a certain distance on a horse + Emily traveled a certain distance on a bike

Let us assume,

Total distance covered by Emily's journey is represented by 'x'

Then we can write,

                          x = 10.981 kilometers + 4.064 kilometers

                          x = 15.045 kilometers

Therefore, Emily's in total journey is 15.045 kilometers.

The transformation of pentagon Q to pentagon Q' is a clockwise rotation of 180° about the origin.

A transformation is a general term for four specific ways to manipulate the shape or position of a point, a line, or a geometric figure.

We have,

Coordinates of a pentagon Q.

(2, 4), (3, 7), (7, 5), (5,4), and (4,2).

Coordinates of pentagon Q'.

(-2, -4), (-3, -7), (-7, -5), (-5,-4), and (-4,-2).

We see that the coordinates of each point of the pentagon Q have changed their position as negative coordinates in pentagon Q'

The coordinates of pentagon Q are in (x, y) which can be assumed to be in the first quadrant of the coordinate plane.

The coordinates of pentagon Q' are in (-x, -y) which is in the 3rd quadrant.

From the first quadrant to 3rd quadrant there is a rotation of 180°.

The solution to the equation √x+4=√3 x is x = 2(1 + √3) or x = 2(1 - √3).

Any equation of the form [tex]\rm ax^2+bx+c=0[/tex] is called a quadratic equation.

The formula for the roots of the quadratic equation is found by:

[tex]\rm x = \dfrac{-b \pm\sqrt{b^2-4ac}}{2a}[/tex]

It is given that:

The equation is:

√x + 4 = √3 x

√x = √3 x - 4

Squaring both sides:

x = (√3 x - 4)²

x = 3x² - 8√3 x + 16

2x² - 8√3 x + 16 = 0

x² - 4√3 x + 8 = 0

After solving with the quadratic formula:

[tex]\rm x = \dfrac{-b \pm\sqrt{b^2-4ac}}{2a}[/tex]

[tex]\rm x = \dfrac{-(-4\sqrt3) \pm\sqrt{(-4\sqrt3)^2-4(1)(8)}}{2(1)}[/tex]

x = 2(1 + √3) or x = 2(1 - √3)

Thus, the solution to the equation √x+4=√3 x is x = 2(1 + √3) or x = 2(1 - √3).

The given expression can be written in its simplest form by solving the exponents.

There are two types of exponent rules that will be applied to the expression. First, we will solve the negative exponent then we will multiply the exponents.

According to the negative exponent rule: x^-n=1/x^n.

Hence, applying the rule to the base term in the denominator, 1/y^⁻³/₄= y^³/₄

Therefore, x^¹/₄ / y^⁻³/₄= x^¹/₄ y^³/₄

According to the multiplication of exponent rule: (x^n)^m=x^nm

Hence, applying the rule to the expression,

(x^¹/₄ y^³/₄)^12=x^¹/₄*12 y^³/₄*12

Multiplying the powers and simplifying,

x^¹/₄*12 y^³/₄*12=x^3y^9

Evaluate g(5) then substitute the value obtained into f(x)

g(5) = [tex]\sqrt{5-1}[/tex] = [tex]\sqrt{4}[/tex] = 2 , then

f(2) = 3(2) + 1 = 6 + 1 = 7

-----------------------------------------------------------------------------

f(x) = [tex]\frac{x^2+3}{(x-4)(x+8)}[/tex]

the denominator of f(x) cannot be zero as this would make f(x) undefined.

equating the denominator to zero and solving gives the values that x cannot be and if the numerator is non zero for these values then they are vertical asymptotes.

(x - 4)(x + 8) = 0

equate each factor to zero and solve for x

x - 4 = 0 ⇒ x = 4

x + 8 = 0 ⇒ x = - 8

the vertical asymptotes are x = 4 and x = - 8
