Answer:

The answer to your question is: x = - 102

Step-by-step explanation:

$- \frac{x}{6} + 1 = 18$

$- \frac{x}{6} = 18 - 1$

$- \frac{x}{6} = 17$

-x = 17 x 6

-x = 102

x = -102

The graph of the function g(x) = x2 + 3x - 4 is shifted 5 units to the left. Plot the zeros of the new function on the provided

Colt1911 [192]

g(x) = x^2 + 3x - 4 (please be sure to use " ^ " to denote exponentiation).

This function factors into g(x) = (x+4)(x-1), and so the zeros are -4 and +1.

If we shift this graph 5 units to the left, we get h(x) = (x+5)^2 + 3(x+5) - 4.

The new zeros will be -4-5 and 1-5, or -9 and -4.

Write the polar form of a complex number in standard form for <img src="https://tex.z-dn.net/?f=25%5Bcos%28%5Cfrac%7B5%5Cpi%20%7

Masja [62]

Answer:

Standard Complex Form : $-\frac{25\sqrt{3}}{2}+\frac{25}{2}i$

Step-by-step explanation:

We want to rewrite this expression in standard complex form. Let's first evaluate cos(5π / 6). Remember that cos(x) = sin(π / 2 - x). Therefore,

cos(5π / 6) = sin(π / 2 - 5π / 6),

π / 2 - 5π / 6 = - π / 3,

sin(- π / 3) = - sin(π / 3)

And we also know that sin(π / 3) = √3 / 2. So - sin(π / 3) = - √3 / 2 = cos(5π / 6).

Now let's evaluate the sin(5π / 6). Similar to cos(x) = sin(π / 2 - x), sin(x) = cos(π / 2 - x). So, sin(5π / 6) = cos(- π / 3). Now let's further simplify from here,

cos(- π / 3) = cos(π / 3)

We know that cos(π / 3) = 1 / 2. So, sin(5π / 6) = 1 / 2

Through substitution we receive the expression 25( - √3 / 2 + i(1 / 2) ). Further simplification results in the following expression. As you can see your solution is option a.

$-\frac{25\sqrt{3}}{2}+\frac{25}{2}i$
