Answer:

$-\frac34 -\frac14 i$

Step-by-step explanation:

Let's start with distributing: $\frac1{4i}-\frac{3i}{4i}$ Simplify i with i in the second term, and rearrange. $-\frac34 +\frac1{4i}$ . Since i in the denominator looks ugly, let's multiply top and bottom by i. $-\frac34 +\frac i{4i^2} = -\frac34 +\frac i{4(-1)} =-\frac34 -\frac14 i$ . The middle passage is based on the fact that, by definition, $i^2=-1$

A farmer is tracking the amount of wheat his land is yielding each year. He finds that the function f(x) = −x2 + 20x + 75 models

mr_godi [17]

Answer:

Average rate of change: 0

Interpretation: No increment in yield from year 5 to year 15.

Step-by-step explanation:

The function that models the yield is:

$f(x)=-x^2+20x+75$

$f(15)=-(15)^2+20(15)+75=150$

$f(5)=-(5)^2+20(5)+75=150$

The average rate of change of f(x) from x=a to x=b is given by the formula;

$AOC=\frac{f(b)-f(a)}{b-a}$

The average rate of change from year 5 to year 15 is:

$\frac{f(15)-f(5)}{15-5}$

$\frac{150-150}{15-5}$

$\frac{0}{10}=0$

Interpretation: There has not been any increment in yield from year 5 to year 15.

A Zoo Has a Elephant to giraffe ratio of 1 to 5. There are 18 Total animals. How many are giraffes? (Please Answer Quickly i rea

Julli [10]

There are 15 giraffes in the zoo.

Let the Elephant be E.

Let the Giraffe be G.

<u>Given the following data:</u>

Total animals = 18 animals

Ratio of E to G = 1:5

Total ratio= 1 + 5 = 6

To find how many of the animals are giraffes:

$G = \frac{Ratio \; of \; giraffe}{Total \; ratio}$ × $Total \; animals$

Substituting the values, we have;

$G = \frac{5}{6}$ × $18$

$G = \frac{90}{6}$

<em>Giraffe, G </em><em>=</em><em> 15 giraffes</em>

Therefore, there are 15 giraffes in the zoo.

Factor completely 2x2 + 9x + 4.

Elden [556K]

Answer:

(2x + 4) ( x +1 ) are factors .

Step-by-step explanation:

Given : 2x² + 9x + 4.

To find : Factor.

Solution : We have given that 2x² + 9x + 4.

On factoring 2x² + 8x + 1x + 4.

Taking common 2x from first two terms and 1 from last two terms .

2x ( x +4 ) +1 (x +4 ).

On grouping

(2x + 4) ( x +1 ).

Therefore , (2x + 4) ( x +1 ) are factors .
