Answer:

Step-by-step explanation:

The two angles add to 80 degrees. Two remote angles always equal the exterior angle not connected to them.

That means that

x + 5 + x - 5 = 80

2x = 80

x = 40

The base angle  is

40 + 40 + y = 180

80 + y = 180

y = 100

Note

You could do this much quicker by noticing that

80 + y = 189

y = 100

No he is not right

The given 2 angles are x + 5 which is 45 and x - 5 which is 35

All he got correct was the fact that the third angle is 100 degrees.

The bottom left angle is 180 -80=(100)

So the remaining 2 angles are equal 80
As all angles in a triangle are equal to 180

X+5 + x - 5 =80
Simplify
2x=80
X=40

Soo one of the angles are 40-5 which is (35)
And the other is 40+5 which is (45)
So sean is not correct
~sorry sean teehee

( I NEED THIS FAST)A speedometer has a percent error of 10%. The actual speed of the car is 40 mph. Select from the drop-down me
ikadub [295]

Answer = 36.0 mph


As per the question,


Actual speed of the car = 40 mph.

Speedometer has a percent error of 10%.

The error can be negative as well as positive.

If the error is negative, it means speedometer is showing less speed than actual speed= - 10%

10  % of 40 = 4

speed shown by speedometer = 40 - (10% of 40) = 36 mph

If the error is positive, it means speedometer is showing more speed than actual speed = +10%

speed shown by speedometer = 40 + ( 10% of 40) = 44 mph

as per the given options, correct option is 36.0 mph

What are ways that people can stand up for something without bringing violence into it?
ANEK [815]

Some ways a person can stand up for something without creating violence is by  creating a blog post on social media, attaching propaganda to bulletin boards outside, starting a go fund me, and lastly they can try to get in connect with someone famous or with a huge following to speak out and agree with the person. And since that celebrity has such a huge fan base their ideas and thoughts will be heard and payed attention to. These are a few ways people can stand up for something without it generating violence.

How to do question 1?Had no idea how to do both parts
givi [52]
y=\dfrac{\ln x}{3x-6}

Differentiate both sides with respect to x:

\dfrac{\mathrm dy}{\mathrm dx}=\dfrac{\frac{3x-6}x-3\ln x}{(3x-6)^2}

When x=1, you have

\dfrac{\mathrm dy}{\mathrm dx}=\dfrac{\frac{3-6}1-3\ln1}{(3-6)^2}=\dfrac{-3}9=-\dfrac13

For part (b), we now assume that x and y are functions of an independent variable, which we'll call t (for time). Now differentiating both sides with respect to t, we have

\dfrac{\mathrm dy}{\mathrm dt}=\dfrac{\frac{3x-6}x-3\ln x}{(3x-6)^2}\dfrac{\mathrm dx}{\mathrm dt}

where the chain rule is used on the right side. We're told that y is decreasing at a constant rate of 0.1 units/second, which translates to \dfrac{\mathrm dy}{\mathrm dt}=-0.1. So when x=1, you have

-0.1=\dfrac{\frac{3-6}1-3\ln1}{(3-6)^2}\dfrac{\mathrm dx}{\mathrm dt}
-0.1=-\dfrac13\dfrac{\mathrm dx}{\mathrm dt}
\dfrac{\mathrm dx}{\mathrm dt}=0.3

where the unit is again units/second.

Determine whether the sequence converges or diverges. If it converges, give the limit.
kakasveta [241]
Well, basically the way I decided to approach the problem was to first find the pattern between the numbers. Its not obvious between 108 and -18, but the pattern is the previous number divided by -6. From there, I believe you should be able to find whether or not it converges or diverges if you know the material (which you should xD)
