To complete the square for the equation x^2 - 9x = 8, the number 81/4 must be added to both sides, resulting in x^2 - 9x + 81/4 = 113/4.

To complete the square for the equation x^2 - 9x = 8, we need to find a number that when added to x^2 - 9x makes it a perfect square trinomial. The formula to complete the square is to take the coefficient of the x term (which is -9), divide it by 2, and square it. The process looks like this:

(-9/2)^2 = 81/4

Therefore, the number to add to both sides of the equation is 81/4. The equation then becomes:

x^2 - 9x + 81/4 = 8 + 81/4

Which simplifies to:

x^2 - 9x + 81/4 = 32/4 + 81/4

x^2 - 9x + 81/4 = 113/4

By adding 81/4 to both sides, we have successfully completed the square.

THE ANSWER IS:

the measure of the arc FH is 48 degrees

and btw I flipping love killing stalking :)

Answer:

[tex]48^{\circ}[/tex]

Step-by-step explanation:

Consider we need to find [tex]m\widehat{FH}[/tex],

Since, if two chords of a circle intersect outside the circle then the measure of intercepted angle is half of the difference of the measures of intercepted arcs.

Thus,

[tex]m\angle ADJ = \frac{m\widehat{AJ}-m\widehat{BE}}{2}[/tex]

By the diagram,

[tex]37^{\circ}=\frac{m\widehat{AJ}-38^{\circ}}{2}[/tex]

[tex]74^{\circ}=m\widehat{AJ}-38^{\circ}[/tex]

[tex]\implies m\widehat{AJ}=74^{\circ}+38^{\circ}=112^{\circ}[/tex]

Now,

[tex]m\angle AGJ = \frac{m\widehat{AJ}-m\widehat{FH}}{2}[/tex]

[tex]32^{\circ}=\frac{112^{\circ}-m\widehat{FH}}{2}[/tex]

[tex]64^{\circ}=112^{\circ}-m\widehat{FH}[/tex]

[tex]\implies m\widehat{FH}= 112^{\circ}-64^{\circ}=48^{\circ}[/tex]

Hence, SECOND OPTION would be correct.

Answer:

This equation is a line

Step-by-step explanation:

We can tell it's a line because both the x and y values are raised to the first power. In order for it to be any of the others, one or both of the variables would have to have a non-one exponent.

Answer:

It is a line.

Step-by-step explanation:

Since, the general equation of,

A line is ax + by = c

A circle is [tex](x-h)^2+(y-k)^2=r^2[/tex]

An ellipse is [tex]\frac{x^2}{a^2}+\frac{y^2}{b^2}=1[/tex]

A parabola is [tex]y^2=4ax[/tex] or [tex]x^2=4ay[/tex]

A hyperbola is [tex]\frac{x^2}{a^2}-\frac{y^2}{b^2}=1[/tex]

Where, a, b and c are constants.

Here, the given equation is,

x + y = 5

Which is the type of ax + by = c

Hence, x + y = 5 is a line.

Answer:

Option B 0.11

Step-by-step explanation:

Given that  the population proportion of 0.58, a simulation of 200 trials is run, each with a sample size of 50 and a point estimate of 0.42. The minimum sample proportion from the simulation is 0.31, and the maximum sample proportion from the simulation is 0.53.

This gives an idea that confidence interval is

(0.31, 0.53) with mean being in the middle of this interval

Margin of error = 1/2 (length of this interval)

Length of confidence interval =[tex]0.53-0.31 =0.22[/tex]

Margin of error =± 1/2(0.22) = ±0.11

Hence option B is correct

Based on the graph of the relationship given between time and the amount of popcorn popped, the relationship doesn't yield a straight line, hence, the relationship isn't proportional.

A proportional relationship is one in which there is a constant change in one variable as the value of the other variable is varied.

A proportional relationship will always yield a straight line with either a positive or negative slope.

Since, the trend line isn't straight, then the relationship isn't proportional.

The actual question is not about the popcorn machine but about testing the hypothesis on mean differences of relaxed and jumping times for eight girls. To assess this, statistical methods like the paired t-test are used to examine the existence of a direct relationship between the two sets of times.

The relationship between time and the amount of popcorn popped could be considered directly proportional if the rate of popping remains constant over time. However, this question appears to be based on a misunderstanding, as it incorrectly states that Rachel had a popcorn machine. Instead, the actual task given is to test the hypothesis that the mean difference between jumping and relaxed times for eight girls at a party would be zero.

To test this hypothesis, a statistical test like a paired t-test could be used to determine if there is a significant difference between the two mean times. Proportionality in the question should be related to rates or ratios. For instance, when data shows a positive correlation as one variable increases, so does the other. This is seen when graphing data that results in a straight line, which signifies a direct relationship.

Therefore, to determine the relationship between two quantities, the concept of direct and indirect proportionalities is important, and having a direct relationship would mean that the variables increase together linearly.

It seems that you are trying to find the length of hair of Florencia on Tuesday.

Given that length of the hair of Florencia on Monday = h centimeters

On Tuesday, she got hair cut.

So new length of the hair of Florencia on Tuesday = 75% of Monday value

= 75% of (h)

= 0.75* (h)

= 0.75h

Hence final answer is the length of the hair of Florencia on Tuesday is ( 0.75h ) centimeters.

Answer:

3/4h and 0.75h

Find where the equation is undefined ( when the denominator is equal to 0.

Since they say x = 5, replace x in the equation see which ones equal o:

5-5 = 0

So we know the denominator has to be (x-5), this now narrows it down to the first two answers.

To find the horizontal asymptote, we need to look at an equation for a rational function: R(x) = ax^n / bx^m, where n is the degree of the numerator and m is the degree of the denominator.

In the equations given neither the numerator or denominators have an exponent ( neither are raised to a power)

so the degrees would be equal.

Since they are equal the horizontal asymptote is the y-intercept, which is given as -2.

This makes the first choice the correct answer.

Solution

The general form of the equation is y = mx + b, where m is the slope and b is the y-intercept.

The given equation is = -1/3 x - 6.

Comparing the given equation with the general form, we get

slope (m) = -1/3 and y-intercept = -6.

The answer is -1/3; -6

The graph of this relation is four points on the coordinate plane (see attached diagram).

A function is a special relation, where each input x has a single output y.

This relation is not a function, because for one x (x=-1), here are two different possible y (y=3 or y=2). If you consider the graph, you can see that there will be vertical line passing through the points (-1,3) and (-1,2). This means that option D is true.

To factor a number out of an expression means to divide each term of the expression by that number.

So, if you want to factor [tex] a [/tex] from the expression [tex] x+y+z [/tex], you'll write it as

[tex] a\left(\dfrac{x}{a}+\dfrac{y}{a}+\dfrac{z}{a}\right) [/tex]

So, the expression becomes

[tex] -10a-25 = -5(2a+5) [/tex]

In this mathematical context, 'f' represents a vehicle's fuel efficiency in miles per gallon, and the given inequality f > 40 mpg indicates that the vehicle's fuel efficiency is higher than 40 miles per gallon.

The problem refers to a situation where a vehicle achieves fuel efficiency of more than 40 miles per gallon. This efficiency is quantified using the variable 'f'.

Considering f as the vehicle's fuel efficiency in miles per gallon, you are expressing a relationship where f > 40 mpg.

Using an example: if we consider a vehicle that achieves 43 miles per gallon, this can be represented as: f = 43 mpg. This efficiency is indeed more than 40 miles per gallon, thus confirming that f > 40 mpg in this case. It's important to understand that in this context, the fuel efficiency varies from one vehicle to another. For instance, vehicles become more fuel efficient over the years due to advancements in technology and heightened fuel economy standards.

Marshall can use x = 8 and y = 0 to show that 8² = 64 using the polynomial identity (x−y)^2=x^2−2xy+y^2.

Marshall can use any values for x and y to show that (x−y)^2=x^2−2xy+y^2. However, he specifically wants to show that 8² = 64. In this case, Marshall can choose x = 8 and y = 0.

Using the polynomial identity (x−y)^2=x^2−2xy+y^2, we substitute x = 8 and y = 0 to get (8 − 0)^2 = 8^2 − 2(8)(0) + 0^2. Simplifying, we have 8^2 = 64 − 0 + 0, which simplifies further to 8^2 = 64.

So, Marshall can use the values x = 8 and y = 0 to show that 8² = 64 using the given polynomial identity.
