Answer:

The best estimate of the solution ordered pair from the graph is [tex](\frac{1}{2},0)[/tex].

Step-by-step explanation:

See the attached graph to this question.

The graph of two straight lines are shown in the graph.

Now, the two straight lines intersect on the x-axis, so the solution ordered pairs should have y-value equals to zero.

But, there are two ordered pairs with y-value zero and they are [tex](\frac{1}{2},0)[/tex] and [tex](\frac{1}{3},0)[/tex].

The best estimate of the solution ordered pairs from the graph is [tex](\frac{1}{2},0)[/tex].

So, this is the solution. (Answer)

Answer:

It’s B if you dont want to read all that.

Step-by-step explanation:

The equation of f(x) is f(x) = -8(4x).

The equation of the reflected function f(x) can be obtained by changing the sign of the coefficient of g(x), which is 8.

So, the equation of f(x) is f(x) = -8(4x).

From given,

Final solution is 260 liter

Let x be the liters of 40 % dye solution

Then, (260 - x) is the liters of 53 % dye solution

Therefore, according to question,

x liters of 40 % dye solution is mixed with (260 - x) liters of 53 % dye solution to get 260 liters of 50 % dye solution

40 % of x + 53 % of (260 - x) = 50 % of 260

Solve for "x"

[tex]\frac{40}{100} \times x + \frac{53}{100} \times (260-x) = \frac{50}{100} \times 260\\\\0.4x+ 0.53(260-x) = 0.5 \times 260\\\\0.4x + 137.8 - 0.53x = 130\\\\0.13x = 137.8 - 130\\\\0.13x = 7.8\\\\Divide\ both\ sides\ by\ 0.13\\\\x = 60[/tex]

Thus 60 liters of 40 % dye solution is used

Then, (260 - x) = 260 - 60 = 200

Thus 200 liters of 53 % dye solution is used

The complete factorized form for the given expression is [tex]\left(9 x^{4}+1\right)\left(3 x^{2}+1\right)\left(3 x^{2}-1\right)[/tex]

Step-by-step explanation:

Step 1: Given expression:

              [tex]81 x^{8}-1[/tex]

Step 2: Trying to factor as a Difference of Squares

Factoring [tex]81 x^{8}-1[/tex]

As we know the theory that the difference of two perfect squares, [tex]A^{2}-B^{2}[/tex]  can be factored into (A+B) (A-B)

from this, when analysing, 81 is the square of 9, [tex]x^{8}[/tex] is the square of [tex]x^{4}[/tex]. Hence, we can write the given expression as,

            [tex]\left(9 x^{4}\right)^{2}-1^{2}[/tex]

By using the theory, we get

           [tex]\left(9 x^{4}+1\right)\left(9 x^{4}-1\right)[/tex]

Again, we can further factorise the term [tex]\left(9 x^{4}-1\right)[/tex]

[tex]9 x^{4}[/tex] is the square of [tex]3 x^{2}[/tex]. Therefore, it can be expressed as below

           [tex]\left(3 x^{2}+1\right)\left(3 x^{2}-1\right)[/tex]

Now, we can not factorise further the term [tex]\left(3 x^{2}-1\right)[/tex]. Because it will come as [tex]\sqrt{3} x[/tex] (3 is not a square term). Thereby concluding that the complete factorisation for the given expression is [tex]\left(9 x^{4}+1\right)\left(3 x^{2}+1\right)\left(3 x^{2}-1\right)[/tex]

Answer:

Average = 96

Step-by-step explanation:

Average = sum of terms/ number of terms

sum of terms = number of burgers sold

number of terms = number of visitors

d =  number of days since Monday which is 7

burgers sold = 200d^3 + 542d^2 + 179d + 1605 substituting d with 7

burgers sold = 200(7)³ +542(7)² + 179(7) +1605

burgers sold =68600 + 26558 + 1253 + 1605

burgers sold =98016

number of visitors= 100d + 321

number of visitors= 100(7) + 321

number of visitors= 700+321

number of visitors= 1021

Average = 98016/1021

Average = 96

Answer:

y = [tex]\frac{1}{8}[/tex] x - 3

Step-by-step explanation:

Use the midpoint formula

Given (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is

[ [tex]\frac{1}{2}[/tex] (x₁ + x₂ ), [tex]\frac{1}{2}[/tex] (y₁ + y₂ ) ]

Here (x₁, y₁ ) = (7, 3) and (x₂, y₂ ) = (9, - 7), thus

midpoint = [ [tex]\frac{1}{2}[/tex] (7 + 9), [tex]\frac{1}{2}[/tex] (3 - 7 ) ] = (8, - 2)

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

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Rearrange 5x - 6 = 2y into this form by dividing all terms by 2

y = [tex]\frac{5}{2}[/tex] x - 3 ← in slope- intercept form

with y- intercept c = - 3 ⇒ (0, - 3 )

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

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂, x₁ )

with (x₁, y₁ ) = (8, - 2) and (x₂, y₂ ) = (0, - 3)

m = [tex]\frac{-3+2}{0-8}[/tex] = [tex]\frac{-1}{-8}[/tex] = [tex]\frac{1}{8}[/tex]

y = [tex]\frac{1}{8}[/tex] x - 3 ← equation of line

BOTH TRIANGLES ARE SIMILAR BY THE AA SIMILARITY POSTULATE.

In first triangle:

Remaining angle = 180° - (70° + 30°)= 80°

In second triangle:

Remaining angle = 180° - (80° + 30°)= 70°

Hence, all the angles of first triangle are congruent to the corresponding angles of the second triangle.

Answer:

formula for sum of interior angles is (n-2)*180 - for a regular polygon

divide that by the number of sides

so 6-2 = 4*180 =720 degrees

720/6 = one angle(angle a) =120

Answer:

D. 120 degrees.

Step-by-step explanation:

We nee to find the measure of the interior angle in a regular hexagon.

The exterior angle = 360 / 6 = 60 degrees.  ( In all convex polygons the sum of the exterior angles = 360 degrees).

So α = 180 - 60 = 120 degrees    (adjacent angles add up to 180 degrees).

Step-by-step explanation:

It is convenient to use a point-slope form of the equation of a line for graphing, since we know the slope is -12 m/min and the point is (30, 0) at sea level.

The horizontal axis is minutes; the vertical axis is meters above sea level. The graph cannot extend below -413 meters from sea level, as that is the lowest place on earth.

The option (D) (r + s) × 5 is correct if the expression is 5 times as much as the sum of r and s.

It is defined as the combination of constants and variables with mathematical operators.

We have a statement about the expression:

The expression is 5 times as much as the sum of r and s

We can frame the expression as follows:

= 5(r + s)

or

= (r + s) × 5

Thus, the option (D) (r + s) × 5 is correct if the expression is 5 times as much as the sum of r and s.

Problem 1

-7+9 is the same as 9+(-7) or 9-7. All of which simplify to 2.

On the other hand, -9+7 is the same as 7+(-9) or 7-9, which simplifies to -2.

Therefore the equation -7+9 = -9+7 becomes 2 = -2, and we can see this is a false equation.

Your second question has some weird typo errors going on. Please update.

Final answer:

The average rate of change of the function g(x) = 3(2^x) - 6 over the interval [0,3] is 7. This is found by evaluating g(x) at x = 0 and x = 3 and then dividing the difference by the interval length.

Explanation:

Calculating Average Rate of Change

The average rate of change of a function over an interval is the change in the function's values divided by the change in the independent variable (often x) over that interval. For the function g(x) = 3(2^x) - 6 over the interval [0,3], we first find the values of g(x) at the endpoints of the interval: g(0) and g(3). We then use the formula for average rate of change:

[tex]\[\text{Average Rate of Change} = \frac{g(3) - g(0)}{3 - 0}\][/tex]

Let's compute:

Now we can substitute these values into the formula:

[tex]\[\frac{18 - (-3)}{3 - 0} = \frac{21}{3} = 7\][/tex]

So, the average rate of change of the function g(x) over the interval [0,3] is 7.

Answer:

Step-by-step explanation:

let x be the width.

length =  x +2

Perimeter = 36 ft

2*( x +2 + x ) =36

2x + 2 = 36/2

2x + 2 = 18

2x = 18 -2 = 16

x = 16/2

x = 8 ft

Width =  8 ft

Length = 8 + 2 = 10 ft

Slope is defined as (y2-y1)/(x2-x1)

"A" gives a slope of (10-6)/(-4-(-1))=4/-3=-4/3

Hope this helped

The point pair establishing a line with a slope of -4/3 is  (-1, 6) and (-4, 10). which is the correct answer would be an option (A).

The slope of a line is defined as the gradient of the line.

To determine the slope of a line, we can use the formula: slope m = (y₂ - y₁)/(x₂ -x₁ )

Using this formula, we can calculate the slope for each of the pairs of points given:

A) (-1, 6) and (-4, 10):

slope = (10 - 6)/(-4 - (-1)) = -4/3

B) (6, -1) and (-4, 10):

slope = (10 - (-1))/(-4 - 6) = -11/10

C) (-1, 6) and (10, -4):

slope = (-4 - 6)/(10 - (-1)) = -10/11

D) (6, -1) and (10, -4):

slope = (-4 - (-1))/(10 - 6) = -3/4

Therefore, the pair of points that defines a line with a slope of -4/3 is (-1, 6) and (-4, 10).
