Answer:

3 or 4, I am confused

Step-by-step explanation:

I'll assume that f(x) = x2 – 2x + 8 is meant to be f(x) = x^2 – 2x + 8

Find the value of f(x) for x = 2:

f(x) = x^2 – 2x + 8

f(2) = (2)^2 – 2*(2) + 8

f(2) = 4 - 4 + 8

f(2) = 8

=============

From the graph, we can find that g(2) = 11

The differece between g(2) and f(2) is thus:

   11 - 8 = 3

3 is not an option, so I wonder if the question is asking for the difference between the absolute maximum of g(x) and f(2).  If so, the maximum for g(x) is 12, at x = 3.  

This would lead to a difference of 12 - 8, or 4.  This is still not an option, so I'm confused.  Perhaps you can find my error and find the ciorrect answer, or at least one that appears in the options.

Answer:

145°

Step-by-step explanation:

35+(5x+5)° = 180° (opposite angles sum up to 180°)

35+5x+5 = 180

40+5x = 180

5x= 180- 40

5x = 140

x = 28

therefore, the missing angle = (5x+5)°

= (5×28+5)= 140+5= 145°

The figure below shows a line graph and two shaded triangles that are similar:

A line is shown on a coordinate grid. The x axis values are from negative 20 to positive 20 in increments of 4 for each grid line. The y axis values are from negative 5 to positive 5 in increments of 1 for each grid line. The line passes through the ordered pairs negative 16, 4, and 0, 0, and 16, negative 4. A shaded right triangle is formed so that its hypotenuse is from ordered pair 0, 0 labeled as O to negative 8, 2 labeled as A, one leg is from 0, 0 to negative 8, 0, and the second leg is from negative 8, 0 to negative 8, 2. Another shaded right triangle is formed with the hypotenuse from negative 8, 2 to negative 12, 3 labeled as B, one leg is from negative 8, 2 to negative 12, 2, and the second leg is from negative 12, 2 to negative 12, 3.

Which statement about the slope of the line is true?

The slope from point O to point A is fraction 1 over 4 times the slope of the line from point A to point B.

The slope from point O to point A is 4 times the slope of the line from point A to point B.

It is fraction negative 1 over 4 throughout the line.

It is −4 throughout the line

Explanation:

Lamont should sample only registered voters to predict who will be elected mayor

A survey is a research method used for collecting data from a predefined group of respondents to gain information and insights into various topics

Since Lamont is trying to predict who will be elected, surveying people that are not registered to vote will not give him an accurate prediction.  If someone is not registered to vote, they cannot vote for any candidate.

To get more accurate results, Lamont should only sample people that are registered voters.

Step-by-step explanation:

Given:

[tex]\bullet \ \ \text{Monday:} \ \dfrac{2}{3} \times \text{Hour}\\\\\bullet \ \text{Wednesday:} \ \dfrac{1}{2} \times \text{Hour}[/tex]

Since Emily only practiced on Monday and Wednesday, the sum of time on both days is the time Emily practiced on the piano for a week.

[tex]\implies \text{Monday + Wednesday = Total time practiced on piano for a week}[/tex]

Substitute the times in the equation

[tex]\implies (\dfrac{2}{3} \times \text{Hour}) + (\dfrac{1}{2} \times \text{Hour}) = \text{Total time practiced on piano for a week}[/tex]

Simplify the equation

[tex]\implies (\dfrac{2}{3} \times 60 \ \text{minutes}) + (\dfrac{1}{2} \times 60 \ \text{minutes}) = \text{Total time practiced on piano for a week}[/tex]

[tex]\implies (20 \ \text{minutes}) + (30 \ \text{minutes}) = \text{Total time practiced on piano for a week}[/tex]

Answer:

{x | x ≠ -1, 2, 4}

Step-by-step explanation:

Domain: input values (x-values)

Asymptote: a line which the curve gets infinitely close to, but never touches.

Hole: a point on the graph where the function is not defined.

From inspection of the graph:

As vertical asymptotes and holes restrict the domain of a rational function, the domain is  {x | x ≠ -1, 2, 4}

The length of the side labeled x is Option B.  [tex]\sqrt{21}[/tex].

Pythagorean theorem is a basic principle to be applied when determining the unknown side of a given right triangle when the values of two sides are given. The theorem states that;

/Hyp/^2 = /Adj/^2 + /Opp/^2

From the triangle given, we have;

/Hyp/^2 = /Adj/^2 + /Opp/^2

x^2 = 4^2 + ((5)^1/2)^2

      = 16 + 5

      = 21

x = 21^1/2

Answer:

The mode would not increase or decrease.

Step-by-step explanation:

I say this because the mode is the value(s) in the data set that occur most frequently. 30 is the mode before adding 80 because 30 is in the set 3 times, more than the other values. Because 80 would be the only 80 in the set it would not become the mode once added. I hope this explained my reasoning and helped!

The true statement for f(x)=b^x is the function is always decreasing function.

We have given,

f(x)=b^x where 0<b<1

Domain is all possible values of x for which any function is defined

We can select any values of x for which function

It will be defined for all real x

So, the domain is [tex](-\infty,\infty)[/tex]

The range is all possible values of y for which x is defined

we are given that b is positive

The value of the function will always be positive

So, the range is  [tex](0,\infty)[/tex]

y>0

The x-intercept:

Set f(x)=0 and then we can solve for x

f(x)=b^x=0

x is undefined

The x-intercept does not exist

Increasing or decreasing:

Since, 0<b<1

The b is a positive value less than 1

As we increase the value of, [tex]b^x[/tex] will keep decreasing

This is decreasing function

In the question we are given ,

And , we have to find the height of cylinder .

We know that ,

[tex]

Our solution starts from here :

[tex] \longmapsto \: \pi \: r {}^{2} h = 225\pi[/tex]

Step 1 : Cancelling π with π :

[tex] \longmapsto \: \cancel{\pi} \: r {}^{2} h = 225 \cancel{\pi}[/tex]

Step 2 : Substituting value of radius which is 5 cm in the formula :

[tex] \longmapsto \: (5) {}^{2} \times h = 225[/tex]

[tex] \longmapsto \: 25h = 225[/tex]

Step 3 : Transposing 25 to right hand side :

[tex] \longmapsto \: h = \frac{225}{25} [/tex]

Step 4 : Cancelling 225 by 25 :

[tex] \longmapsto \: \red{\boxed{h = 9 \: cm}}[/tex]

[tex]y = - x - 1[/tex]

[tex]y = - 5x - 13[/tex]

[tex]y = - x - 1[/tex]

[tex] - y = 5x + 13[/tex]

[tex]0 = 4x + 12[/tex]

[tex]4x = - 12[/tex]

[tex]x = \frac{ - 12}{4} = - 3[/tex]

[tex]y = - x - 1[/tex]

[tex]y = - ( - 3) - 1[/tex]

[tex]y = 3 - 1 = 2[/tex]

Let's start the sum as follows:

x³ = 8

X × X × X = 8

This means there are 3 number which after Multiplication gives answer 8.

If 2 is multtiplied 3 times it will give you 8

Thus the answer of x is 2

x = 2.

x^3 = -8

The cube root of 8 is 2 = 2 x 2 x 2 is 8.

But, the answer is negative, which means that the cube root of -8 must be -2.

-2 x -2 x -2 = -8

x = -2

Step-by-step explanation:

D on edge 2022

Given:

Angle 6 = 25 degrees

To Find:

The value of Angle 7

Solution:

We know that,

the value of Angle 6 is equal to 25 Degrees

Since Angle 6 and Angle 7 together comprise of a Straight Line, this means that they are Supplementary Angles.

Therefore,

Angle 6 + Angle 7 = 180 degrees

This implies that,

25 degrees + Angle 7 = 180 degrees.     (since Angle 6 = 25 Degrees)  

Angle 7 = (180-25) degrees

Thus ,

Angle 7 = 155 degrees

Hence, Angle 7 is  155 degrees (Option 1)
