What's the solution to -182=2(1+2x)-2

Answers

-182=2(1+2x)-2

2*1=2
2*2x=4x

-182=4x+2-2
-182=4x
-45.5=x

Answer: [tex]x = -\frac{91}{2}[/tex]

Step-by-step explanation:

If you have any questions, feel free to ask :)

Step 1: Add [tex]2[/tex] to both sides.

[tex]-182 + 2 = 2(1 + 2x)[/tex]

Step 2: Simplify [tex]-182 + 2[/tex] to [tex]-180[/tex].

[tex]-180 = 2(1 + 2x)[/tex]

Step 3: Divide both sides by [tex]2[/tex].

[tex]-\frac{180}{2} = 1 + 2x[/tex]

Step 4: Simplify [tex]\frac{180}{2}[/tex] to [tex]90[/tex].

[tex]-90 = 1 + 2x[/tex]

Step 5: Subtract [tex]1[/tex] from both sides.

[tex]-90 - 1 = 2x[/tex]

Step 6: Simplify [tex]-90 - 1[/tex] to [tex]-91[/tex].

[tex]-91 = 2x[/tex]

Step 7: Divide both sides by [tex]2[/tex].

[tex]-\frac{91}{2} = x[/tex]

Step 8: Switch sides.

[tex]x = -\frac{91}{2}[/tex]

eighteen individuals who use a particular form of social media were assigned a new user interface to use when logging into their accounts. after using the new user interface for a week, each individual was asked to rate how easy or hard the new user interface was to use on a scale from 1 (extremely easy) to 9 (extremely hard). which of the following correctly identifies why this is not a well designed experiment?

A. There was a lack of control because not all individuals in the study used login passwords of the same length

B. The individuals may not have been randomly selected

C. There was not enough replication because the individuals used the new user interface for only one week.

D. there was a lack of control because not all individuals in the study use social media

E. the study was not comparative- only one treatment was used.

Answers

Answer:

E: The study was not comparative—only one treatment was used.

Step-by-step explanation:

Well-designed experiments should involve comparisons of at least two treatment groups, one of which could be a control group.

A well-designed experiment investigates design features that achieve the research to rule out sources of variation as reasons for the observed relationship between both the independent variable(s) and the predictor variables.

Studies that are well should include a comparison of at least two treatments, one of which may be a controlled study.Eighteen people using a specific type of social media are given a different user interface to utilize when login onto their account. After a day of just using the new user interface, each participant was asked to rate as difficult or easy it was to use the new interface on a scale of 1 to 9.The study was not properly comparative since it identified just one treatment that was not used as the well-designed study.

Therefore, the final answer is "Option E".

According to the Exterior Angle Theorem, the true statement should be considered as the option b.

What is an Exterior Angle Theorem?

The exterior angle theorem defined that at the time when a triangle's side should be extended, the resultant exterior angle formed should be equivalent to the sum of the measures of the two opposite interior angles of the triangle.

So based on this, we can say that the option b is correct.

A quadratic function y = f(x) is plotted on a graph and the vertex of the resulting
parabola is (6, -3). What is the vertex of the function defined as
g(x) = f(-x) - 3?

Answers

Answer: (-6, - 6)

Step-by-step explanation:

Here we have two transformations, and the first step will be to explain those transformations:

Reflection over the y-axis.

For a function f(x), the reflection over the y-axis is written as:

g(x) = f(-x)

Then if we initially had a point (x, y), the transformed point will be (-x, y).

Vertical translation.

We can define a vertical translation of N units as:

g(x) = f(x) + N

if N > 0, the translation is up.

If N < 0, the translation is down.

Then if we start with a point (x, y), the transformed point will be (x, y + N)

In the case of this problem we have g(x) = f(-x) - 3

This means that N = -3

Then if we initially had the vertex at the point (6, - 3)

The transformed point will be: changing the sign of the x-component and subtracting 3 in the y-component, then the transformed vertex point is:

(-6, -3 - 3) = (-6, - 6)

The vertex of the resulting  parabola will be (-6, -6)

Rule of reflection

Given the function y= f(x), plotted on a graph and the vertex of the resulting

parabola is (6, -3), if this coordinate is reflected over the y-axis, the reflection rule will be:

[tex](x,y) \rightarrow (-x, y)[/tex]The coordinate (6, -3) under this translation will give (-6, -3)

To get the corresponding function [tex]g(x) = f(x) - 3\\[/tex]

[tex]g(x) = [(-6, -3) - 3]\\g(x) = (-6, -3-3)\\g(x) =(-6, -6)[/tex]

Hence the vertex of the resulting  parabola will be (-6, -6)

How far up a wall will a 13-meter ladder reach, if the foot of the ladder is 6 meters away from the base of the wall?



A. 12 m
B. 4 m
C. 133 m
D. 245 m

Answers

Answer: C

Step-by-step explanation: I took the test!!

The required distance that the ladder foot away from the base of the wall is √133  meters. Option C is correct.

What are Pythagorean triplets?  

In a right-angled triangle, its side, such as hypotenuse, perpendicular, and base is Pythagorean triplets.

Here,
Let the base length be x,
According to the question, a 13-meter ladder reach, the foot of the ladder is 6 meters.
So, applying the Pythagoras theorem,
13² = 6² + x²
x = √169 - 36
x = √133

Thus, the required distance that the ladder foot away from the base of the wall is √133  meters.

If the population of a certain county was 100,000 in 1998 and 110,429 in 2008, and if the formulay = P0ehtapplies to the growth of the county's population, estimate the population of the county in 2023. (P0 is the initial population. Round your value of h to four decimal places. Round your answer to the nearest whole number.)

Answers

Answer:

126807 people

Step-by-step explanation:

Given;

P= Poe^ht

Where;

P= population at time t

Po= population at the beginning

h= growth constant

t= time

1998- 2008 is ten years.

110429= 100,000e^10h

1.1 = e^10h

ln(1.1) = lne^10h

0.095 = 10h

h= 0.0095

In 2023, t = 25 years

P= 100,000e^(0.0095 × 25)

P= 126807 people

A plane set off to Portland at a speed of 232 mph. On the
return flight of 12 hours, the plane cruised at 204 mph.
How many hours long was the flight to Portland?

Answers

Answer:

The flight to Portland takes 10.6 hours.

Step-by-step explanation:

To find the time of flight to Portland we need to calculate the distance traveled by using the equation:

[tex] x = v*t [/tex]

Where:

v: is the speed = 204 mph (return flight)

t: is the time = 12 h (return flight)

[tex] x = v*t = 204 mi/h*12 h = 2448 mi [/tex]

Now, we can find the time of flight to Portland using v = 232 mph:

[tex]t = \frac{x}{v} = \frac{2448 mi}{232 mi/h} = 10.6 h[/tex]

Therefore, the flight to Portland takes 10.6 hours.
