Find the values of m and b that make the following function differentiable.
Sonbull [250]
The derivative of f(x) at x=3 is 2x=6 approaching from the left side (apply power rule to y=x^2). The derivative of f(x) at x=3 is m approaching from the right side. In order for the function to be differentiable, the limit of derivative at x=3 must be the same approaching from both sides, so m=6. Then, x^2=mx+b at x=3, plug in m=6, 9=18+b, so b=-9.

Last season Ellen and Janet together won 32 tennis matches Ellen won 6 more than then Janet How many more matches did Ellen win
joja [24]

T = J + E

T = J + (J + 6)

T = 32

32 = 13 + (13 + 6)

32 = 13 + 19

32 = 32

Ellen won 19 matches.

Pls help<br> will mark brainliest
yanalaym [24]

Answer:

1.93433

Step-by-step explanation:

Since all triangles have an interior angle sum of 180, the second angle is 45. this also means that x and y are equal. Using the pythagorean theorem, we can produce the equation 2\sqrt{14} = 2x^2. dividing both sides by two we get x^2= \sqrt{14}. when we take the square root of root 14 we get 1.934335

PLS HELP ME WITH THIS!!!!!! HOW DID THEY GET 80ft^2

\huge \boxed{\mathfrak{Question} \downarrow}

  • Determine the surface area of the right square pyramid.

\large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}

The formula for finding the surface area of a right square pyramid is ⇨ b² + 2bl, where

  • b = base of the right square pyramid
  • l = slant height of the right square pyramid.

In the given figure,

  • base (b) = 4 ft.
  • slant height (l) = 8 ft.

Now, let's substitute the values of b & l in the formula & solve it :-

\sf \: {b}^{2}  + 2bl \\  =   \sf \: {4}^{2}  + 2 \times 4 \times 8 \\  =  \sf \: 16 + 8 \times 8 \\  =  \sf \: 16 + 64 \\  =  \huge\boxed{\boxed{ \bf 80 \: ft ^{2} }}

So, the surface area of the right square pyramid is <u>8</u><u>0</u><u> </u><u>ft²</u><u>.</u>
