Answer:

Tan A=4/3

Step-by-step explanation:

So, you start the equation with finding the opposite and the adjacent side for tangent. Then, put together the equation- tan(a)=40/30. 40/30=4/3.

(hope this helps!!)

What are the 2 \ 3 parts of a right angle in a whole wheel?

leonid [27]

Answer:

$\frac{2}{3} \ part \ of \ right \ angle \ is \ \frac{1}{6} \ part \ of \ a \ whole \ wheel.$

Step-by-step explanation:

$\frac{2}{3} \ of \ a \ right \ angle \ = \frac{2}{3} \times 90^{\circ} = 60^{ \circ}\\\\A \ whole \ wheel \ is \ = 360^ {\circ}\\\\$

$Let \ it \ be \ x\\\\x \times 360 = 60 \\\\x = \frac{60}{360} = \frac{1}{6}$

Therefore ,

$\frac{2}{3} \ part \ of \ right \ angle \ is \ \frac{1}{6} \ part \ of \ a \ whole \ wheel.$

How do you find the limit of # (3 x^4 + 4) / ((x^2 - 7)(4 x^2 - 1)) # as x approaches infinity?

KengaRu [80]

$\displaystyle\lim_{x\to\infty}\frac{3x^4+4}{(x^2-7)(4x^2-1)}$

Expanding the denominator gives

$(x^2-7)(4x^2-1)=4x^4-29x^2+7$

Then in the whole rational expression, we can divide through by $x^4$ . Since $x\to\infty$ , we assume that $x>0$ , so this is legal.

$\dfrac{3x^4+4}{4x^4-29x^2+7}=\dfrac{3+\frac4{x^4}}{4-\dfrac{29}{x^2}+\dfrac7{x^4}}$

As $x$ gets arbitrarily large, the rational terms in the numerator and denominator become negligible. So for large $x$ , we have

$\dfrac{3x^4+4}{(x^2-7)(4x^2-1)}\approx\dfrac34$

And so the limit is $\dfrac34$ .

rate of change of distance = speed

speed = distance/time

speed = (400 km)/(10 h)

speed = 40 km/h
