A: 12 9/10
B: 12 3/4
C: 206 2/5
D: 47 3/5
Answers
Answer:
a
Step-by-step explanation:
51 3/5 = 258/5
258/5 / 4 = 12.9 (meters the submarine dives each min)
now we have to find out what 12.9 is as a fraction!
12.9= 12 9/10 because .9 is equal to 9/10, and 12. equals 12!

Answers
Answer: 235
Step-by-step explanation:

[tex]x=89[/tex]
Step-by-step explanation:
We can plug into the formula for the mean to get [tex](87+73+84+82+x)/5=83[/tex].
We can combine like terms on the left side to get [tex](326+x)/5=83[/tex].
We can multiply by [tex]5[/tex] on both sides to get [tex]326+x=415[/tex].
We can finally subtract [tex]326[/tex] from both sides to get [tex]x=89[/tex].
So, the answer is [tex]\boxed{x=89}[/tex] and we're done!

What is the value of x?
Enter your answer in the box.
Answers
Answer:
x = 50
Step-by-step explanation:
→ Make the equations equal to each other
2 ( x + 10 ) = 3x - 30
→ Expand brackets
2x + 20 = 3x - 30
→ Minus 3x from both sides
-x + 20 = -30
→ Minus 20 from both sides
-x = -50
Opposite angles are equal
[tex]\\ \sf\longmapsto 2(x+10)=3x-30[/tex]
[tex]\\ \sf\longmapsto 2x+20=3x-30[/tex]
[tex]\\ \sf\longmapsto 3x-2x=30+20[/tex]

[tex]y = x + \pi[/tex]
Step-by-step explanation:
We need to find the slope of the line tangent to y at [tex]x=-\pi[/tex] and we can do that by calculating the derivative of y at that point. We know that
[tex]y'(x) = \dfrac{d}{dx}(\tan{x}) = \sec^2{x}[/tex]
and
[tex]y'(-\pi) = \sec^2(-\pi) = 1[/tex]
To find the equation of the tangent line, we know that the line passes through the point [tex](-\pi, 0)[/tex] so we can write the slope-intercept form of the line's equation as
[tex]0 = (-\pi) + b \Rightarrow b = \pi[/tex]
Therefore, the equation of the line tangent to the point [tex]x = -\pi[/tex] is
[tex]y = x + \pi[/tex]
The graph of the two functions is shown above.
