Line SU intersects Line TV at point R. What is the value of x, in degrees?

umka2103 [35]

Answer: X is equal to 30

Step-by-step explanation: I found this by taking 75 + 15 which is 90 then dividing it by 3 so 30. This is correct because since the linear pair is equal to 75 degrees then this also needs to be 75 degrees and 3 x 30 = 90 and 90 - 15 = 75.

Hope this helps.

What symbol makes this comparison true? 200 mL O 2 L <>

vova2212 [387]

Answer:

For the first case converting ml to L we got:

$200mL *\frac{1L}{1000 mL}= 0.2 L$

And we see that 0.2 L is lower than 2 L so then:

$200 mL < 2L$

And in the other way if we convert L to mL we got:

$2L *\frac{1000mL}{1L} = 2000 mL$

And we see that [/tex] 200mL < 2000 mL[/tex]

So then the answer would be <

Step-by-step explanation:

For this case we can solve this problem converting ml to L or converting L to ml.

For the first case converting ml to L we got:

$200mL *\frac{1L}{1000 mL}= 0.2 L$

And we see that 0.2 L is lower than 2 L so then:

$200 mL < 2L$

And in the other way if we convert L to mL we got:

$2L *\frac{1000mL}{1L} = 2000 mL$

And we see that [/tex] 200mL < 2000 mL[/tex]

So then the answer would be <

This seems to be calculus 1.

Question a

We have $-2x^3 + 5x^2 + 9$

m = slope = derivative

Find the derivative / slope of $-2x^3 + 5x^2 + 9$

We do this by differentiating the polynomials. There are a few methods to do this but I am going to use the power rule, which we multiply the constant by the exponent on the variable and subtract one from the exponent.

$\frac{d}{dx}(-2x^3 + 5x^2 + 9)$
