Divide x to the 1 half power divided by x to the 2 sevenths power.

Answers

Answer 1

Answer: remember some basic rules
$(x^m)/(x^n)=x^(m-n)$
and
$x^ (m)/(n)= \sqrt[n]{x^m}$

so
$(x^(1)/(2))/(x^(2)/(7))=x^{(1)/(2)-(2)/(7)}$
1/2-2/7=
7/14-4/14=
3/14

$x^{(1)/(2)-(2)/(7)}=x^{(3)/(14)}$

$x^ (3)/(14)= \sqrt[14]{x^3}$

Find the exact value of tan (arcsin (2/5)). For full credit, explain your reasoning.

Answers

Since arcsin(2/5)=x, sin x=2/5

Here we go $=sinx/(sqrt(1-sin^2x)) =(2/5)/(sqrt(1-4/5))$
$tan x = sinx/cosx$
More than one way possible :
$tan(arcsin(2/5)) =(2/5)/ (sqrt(21)/5)=2/sqrt(21)$

Which is f(5) for the function –2x2 + 2x – 3? –107 –63 –43 –37

Answers

If f(x) = - 2x² + 2x - 3, then f(5) will be
$f(x)=- 2x^(2) + 2x - 3\n f(5)=- 2(5)^(2) + 2(5) - 3\n f(5)=- 2(25) + 10 - 3\n f(5)=-50 + 10 - 3\n f(5)=-43$

Thus, your answer is C, -43.

You can just put that value 5 in place of x and then evaluate the output.

The value of f(5) for the given function is given by:

Option C: -43

How to evaluate functions on a given point?

Use the definition of function to evaluate the function on a given point. Most of the time, in general cases, the function will be algebraic and you just need to replace the input variables with the value of the point you want to evaluate the function on.
