Answer:

y = 1/2 x

Step-by-step explanation:

We have the slope of 1/2 and a point of (4,2)

We can use point slope form

y-y1 = m(x-x1)

y-2 = 1/2(x-4)

Distribute

y-2 = 1/2x -2

Add 2 to each side

y-2+2 = 1/2 x -2+2

y = 1/2 x

This is in slope intercept form

At sea level, the boiling point of water is 100°C. At an altitude of 7 km, the boiling point of water is 75.5°C. Find a linear f

enot [183]

Answer:

$T(8.85\,km) = 69.025\,^{\textdegree}C$

Step-by-step explanation:

Let assume that boiling point of water diminish linearly with the increase on altitude. Then, the expression needed is this first order polynomial:

$T(z) = \frac{75.5\,^{\textdegree}C-100\,^{\textdegree}C}{7\,km-0\,km}\cdot z + 100\,^{\textdegree}C$

The boiling point of water at a height of 8.85 km is:

$T(8.85\,km) = 69.025\,^{\textdegree}C$

Given the function f ( x ) = x^2 + 7 x + 10/ x^2 + 9 x + 20 Describe where the function has a hole and how you found your answer

ryzh [129]

${x}^{2} + 7x + \frac{10}{ {x}^{2} } + 9x + 20 \\ = {x}^{2} + 16x + \frac{10}{ {x}^{2} } + 20 \\ x = 0 \\ \frac{10}{ {x}^{2} } = \frac{10}{0}$

= undefined

It is undefined as you cannot divide by zero. Hence, there is a hole at x = 0.
