Answer:

Option C $\frac{1}{2}(185\°-x\°)=76\°$

Step-by-step explanation:

we know that

The measurement of the <u>exterior angle</u> is the semi-difference of the arcs it comprises

$76\°=\frac{1}{2}(arc\ ST-arc\ XZ)$

we have

$arc\ ST=185\°$

$arc\ XZ=x\°$

substitute

$76\°=\frac{1}{2}(185\°-x\°)$

Rewrite

$\frac{1}{2}(185\°-x\°)=76\°$

Which of the values shown are potential roots of f(x) = 3x3 – 13x2 – 3x + 45? Select all that apply.

galina1969 [7]

Answer:

All potential roots are 3,3 and $-\frac{5}{3}$ .

Step-by-step explanation:

Potential roots of the polynomial is all possible roots of f(x).

$f(x)=3x^3-13x^2-3x+45$

Using rational root theorem test. We will find all the possible or potential roots of the polynomial.

p=All the positive/negative factors of 45

q=All the positive/negative factors of 3

$p=\pm 1,\pm 3,\pm 5\pm \pm 9,\pm 15\pm 45$

$q=\pm 1,\pm 3$

All possible roots

$\frac{p}{q}=\pm 1,\pm 3,\pm 5\pm \pm 9,\pm 15\pm 45,\pm \frac{1}{3},\pm \frac{5}{3}$

Now we check each rational root and see which are possible roots for given function.

$f(1)= 3\times 1^3-13\times 1^2-3\times 1+45\Rightarrow 32\neq 0$

$f(-1)= 3\times (-1)^3-13\times (-1)^2-3\times (-1)+45\Rightarrow \neq 32$

$f(-3)= 3\times (-3)^3-13\times (-3)^2-3\times (-3)+45\Rightarrow \neq -144$

$f(3)= 3\times (3)^3-13\times (3)^2-3\times (3)+45\Rightarrow =0\\\\ \therefore x=3\text{ Potential roots of function}$

Similarly, we will check for all value of p/q and we get

$f(-5/3)=0$

Thus, All potential roots are 3,3 and $-\frac{5}{3}$ .

Write an equation that represents degrees fahrenheit in terms of degrees celsius. let xx represent the temperature in degrees ce

IgorC [24]

As we know Conversion from fahrenheit to celsius is
$F - 32 = \frac{9C}{5}$

We can write it also as

$F = \frac{9C}{5}+32$

F as y and C as x then we can write it as

$y = \frac{9x}{5} + 32$
