FIVE STARS AND BRAINLIEST FOR CORRECT ANSWER

Charra [1.4K]

For the given vectors $\vec{a}=a_{1}\hat{i}+a_{2}\hat{j}$ and $\vec{b}=b_{1}\hat{i}+b_{2}\hat{j}$

The dot product of vectors a and b is defined as = $\vec{a}.\vec{b}=(a_{1}\times b_{1}+a_{2} \times b_{2})$

So, $\vec{a}.\vec{b} = (4\hat{i}+3\hat{j}). (-4\hat{i}+4\hat{j})$

$\vec{a}.\vec{b}=(4\times(-4)+3 \times4)$

= -16+12

= -4

Assume that when adults with smartphones are randomly selected, 57% use them in meetings or classes. If 8 adult smartphone use

vovikov84 [41]

Answer:

≈ 0.2526

Step-by-step explanation:

The number of combinations of 4 out of 8:

8C4 = 8!/(4!(8-4)!)= 8*7*6*5/(1*2*3*4)= 70

Success factor is:

57% = 0.57

and failure factor is:

(100 - 57)%= 43%= 0.43

Probability:

0.57⁴*0.43⁴*70 ≈ 0.2526

Use the algebraic procedure explained in section 8.9 in your book to find the derivative of f(x)=1/x. Use h for the small number

Triss [41]

Answer:

By definition, the derivative of f(x) is

$lim_{h\rightarrow 0}\frac{f(x+h)-f(x)}{h}$

Let's use the definition for $f(x)=\frac{1}{x}$

$lim_{h\rightarrow 0} \frac{\frac{1}{x+h}-\frac{1}{x}}{h}=\\lim_{h\rightarrow 0} \frac{\frac{x-(x+h)}{x(x+h)}}{h}=\\lim_{h\rightarrow 0} \frac{\frac{(-1)h}{x^2+xh}}{h}=\\lim_{h\rightarrow 0} \frac{(-1)h}{h(x^2+xh)}=\\lim_{h\rightarrow 0} \frac{-1}{x^2+xh)}=\frac{-1}{x^2+x*0}=\frac{-1}{x^2}$

Then, $f'(x)=\frac{-1}{x^2}$
