Answer:

○ $\displaystyle f(x + 1) = x^3 + 4x^2 + 3x + 1$

Step-by-step explanation:

When shifting to the left, you use, in the form of $\displaystyle x - c,$ $\displaystyle x + 1,$ in which −c gives you the OPPOSITE terms of what they really are.

30 is what percent of 120?

sergeinik [125]

Answer:

25%

Step-by-step explanation:

30 is what percent of 120

Is means equals

of means multiply

30 = P * 120

Divide by 120 on each side

30/120 = P*120/120

1/4 = P

.25 = P

Now put this in percent form

.25 * 100% = P

25 % = P

Let $a$ be the length of the leg with one tick mark and $b$ the length of the leg with two tick marks.

In the upper triangle, the law of cosines says

$6^2=a^2+b^2-2ab\cos43^\circ$

In the lower triangle, it says

$4^2=a^2+b^2-2ab\cos(4y-5)^\circ$

Subtract the second equation from the first to eliminate $a^2+b^2$ :

$6^2-4^2=-2ab(\cos43^\circ-\cos(4y-5)^\circ)$

$10=ab(\cos(4y-5)^\circ-\cos43^\circ)$

$a$ and $b$ are lengths so they must both be positive. 10 is also positive, so in order to preserve the sign on both sides of this equation, we must have

$\cos(4y-5)^\circ-\cos43^\circ>0$

$\cos(4y-5)^\circ>\cos43^\circ$

Now we have to be a bit careful. If $x$ is an acute angle, then as $x$ gets larger, the value of $\cos x$ gets smaller. So if we have two angles $\theta$ and $\varphi$ , with $0^\circ$ , then we would have $\cos\theta>\cos\varphi$ .
