Someone please help me answer this!!
lianna [129]

Answer:

7.1 units is the answer

Step-by-step explanation:

d=\sqrt{(x_2-x_1)^2 + (y_2-y_1)^2} \\\\d=\sqrt{(6-1)^2 + (2-7)^2}\\\\d=\sqrt{(5\\)^2+(-5)^2} \\\\d=\sqrt{25+25} \\\\d=\sqrt{50} \\\\d=7.071..

Rounding off,

d = 7.1 units

Find the values of m and b that make the following function differentiable.
dimaraw [331]
Now, bearing in mind that, for a graph, to be "differentiable", means a "smooth transition", not an abrupt edge or a "cusp", the first subfunction of the piece-wise is just a quadratic, the second subfunction is a linear, well, so the linear needs to hit the quadratic "smoothly", not make an abrupt edge, for that, the linear must continue the quadratic from 2 onwards, since 2 is the range edge.

now, what is the piece-wise when x = 2? well, f(2) = x² or (2)² or 4

that means, the linear needs to hit it at that point, to make it so, let's make it the slope of the linear, the same as the quadratic's.

what's the quadratic's slope? well, simple enough

\bf \left. \cfrac{dy}{dx}=2x \right|_{x=2}\implies 4\impliedby \textit{this means }
\begin{array}{llll}
mx+b\\
\uparrow \\
4
\end{array}

so we have y = 4x + b

now, recall, for the quadratic, when x =2, y = 4, so for the linear, when x = 2, y = 4 as well, this means

\bf 4 = 4(2) + b\implies 4=8+b\implies 4-8=b\implies \boxed{-4=b}
\\\\\\
mx+b\implies 4x-4\\\\
-------------------------------\\\\
f(x)=
\begin{cases}
x^2&x\le 2\\
4x-4&x\ \textgreater \ 2
\end{cases}

a shopper 48 hot dogs the store sells identacal ht dogs in two diffrent sized packets the sell a six pack of hot dogs for 2.10 a
seraphim [82]

Answer:

The shopper should but the 6 pcs pack because its cheaper.

Step-by-step explanation:

6-pcs pack = $2.10

hot dogs needed = 48

number of 6 pcs = 48 divided 6 = 8

total cost = $2.10 x 6 = $16.80

8 pcs pack = $3.12

hot dogs needed = 48

number of 8 pcs packs = 48 divided 8= 6

total cost = $3.12 x 6 =$18.72

hope it helps :)
