<span>If an equation shows a relationship between x and y in which the value of y is dependent upon the value of x, y is known as the dependent variable and is sometimes referred to as 'function(x)' or f(x). The final solution of the equation, y, depends on the value of x, the independent variable which can be changed.</span>

Need help with this continuity problem.

ira [324]

In order to be continuous everywhere, we only need to satisfy continuity at $x=10$ . For that to happen, we need to have

$\displaystyle\lim_{x\to10^-}f(x)=\lim_{x\to10^+}f(x)=f(10)$

By the function's definition, $f(10)=2(10)-2=18$ . Compute the limits:

$\displaystyle\lim_{x\to10^-}f(x)=\lim_{x\to10}2x-2=18$

$\displaystyle\lim_{x\to10^+}f(x)=\lim_{x\to10}-8x+b=-80+b$

So we must have

$18=b-80\implies b=98$

The record low temperature in Hawaii is -0.15 times the record low temperature in Alaska. The record low temperature in Hawaii i

Luba_88 [7]

Answer:the record low temperature in Alaska = -80°F

Step-by-step explanation:

Step 1

Let the temperature in Alaska be = x

such that the temperature in Hawaii be -0.15 times temperature in Alaska = -0.15 x.

Step 2

IF the record low temperature in Hawaii is 12°F.

Alaska = ??

We know that

Hawaii= -0.15 x temperature Alaska ( 0.15 x)

12°F=-0.15 x temperature Alaska(x)

Temperature of Alaska, x = 12°F/-0.15

= -80°F
