Answer:

The slope is -0.25. This means that the power reduces by 0.25 percent per hour

Step-by-step explanation:

Given

y = -0.25x + 1

Required

Identify and interpret the slope

An equation has a general form:

y = mx + b

Where

m = slope

Compare y = mx + b to y = -0.25x + 1

We have:

mx = -0.25x

Divide both sides by x

\frac{mx}{x} = \frac{-0.25x}{x}

m = \frac{-0.25x}{x}

m = -0.25

Because the result of the above calculation is negative, it means that the function reduces

<em>The given function measures the percentage of power by hour.</em>

<em>So, the power reduces by 0.25% per hour</em>

Find the missing term (need help)
katen-ka-za [31]

Answer:

x² - 10x + 34

Step-by-step explanation:

given the roots are x = 5 ± 3i then the factors are

(x - (5 + 3i))(x - (5 - 3i))

= (x - 5)² - 9i² ← expand (x - 5)²

= x² - 10 x + 25 + 9 → [ i² = - 1 ]

= x² - 10x + 34

the missing term is 10x
