You are adding 15 each time, so 60 + 15 = 75

The next item is 75.

At which value will the graph of y=tanx have a zero? Please explain the correct answer!

Rina8888 [55]

Answer: None of the above are correct.

Step-by-step explanation:

Given function: $y=\tan x$

We know that the value of tan x =0 at x=0.

Also, $At\ x=\frac{\pi}{3},\ \tan\frac{\pi}{3}=\sqrt{3}$

$At\ x=\frac{\pi}{2},\ \tan\frac{\pi}{2}=\infty$

$At\ x=\frac{\pi}{3},\ \tan\frac{\pi}{4}=1$

Hence, the only option is correct is "None of the above are correct".

What is the answer for X^3=8/27

maksim [4K]

Answer:

x = 2 /3

Step-by-step explanation:

x^3 = 8/27

Take the cube root of each side

(x^3)^1/3 = (8/27)^1/3

We know that (a/b) ^c = a^c / b^c

x = (8 ) ^1/3 / (27)^1/3

x = 2 /3

Find the cosine of R.

JulijaS [17]

Answer:

$cos(R) = \frac{\sqrt{15}}{5}$

Step-by-step explanation:

To find the cosine of <R, apply the following trigonometric ratio formula:

$cos(R) = \frac{adjacent}{hypotenuse}$

Adjacent = 3

Hypotenuse = √15

Plug in the values into the formula

$cos(R) = \frac{3}{\sqrt{15}}$

Multiply the numerator and denominator by √15 to rationalize.

$cos(R) = \frac{3 \times \sqrt{15}}{\sqrt{15} \times \sqrt{15}}$

$cos(R) = \frac{3\sqrt{15}}{(\sqrt{15})^2}$

$cos(R) = \frac{3\sqrt{15}}{15}$

$cos(R) = \frac{\sqrt{15}}{5}$
