Evaluate the function.<br> f(x) = 3x2 + 16<br> Find f(-1)

SIZIF [17.4K]

Answer:

$f(-1)=19$

Step-by-step explanation:

<u>Evaluating Functions</u>

Given a function y=f(x), evaluate the function for x=a means substituting the variable for the given value.

We have the function:

$f(x)=3x^2+16$

Find f(-1):

$f(-1)=3(-1)^2+16$

$f(-1)=3(1)+16$

$f(-1)=3+16$

$\boxed{f(-1)=19}$

]solomon needs to justify the formula for the arc length of a sector. which expression best completes this argument? the circumf

Anna35 [415]

Answer:

$\frac{2 \pi r}{\frac{360^{\circ}}{n^{\circ}}}$ best completes this argument

Step-by-step explanation:

Circumference of circle = $\pi \cdot d$

Where d is the diameter of circle

We are given that if equally sized central angles, each with a measure of n°, are drawn, the number of sectors that are formed will be equal to $\frac{360^{\circ}}{n^{\circ}}$

So, Number of sectors = $\frac{360^{\circ}}{n^{\circ}}$

The arc length of each sector is the circumference divided by the number of sectors

$\Rightarrow \frac{\pi \cdot d}{\frac{360^{\circ}}{n^{\circ}}}$

Diameter d = 2r (r = radius)

$\Rightarrow \frac{2 \pi r}{\frac{360^{\circ}}{n^{\circ}}}$

Option b is true

Hence $\frac{2 \pi r}{\frac{360^{\circ}}{n^{\circ}}}$ best completes this argument
