Given the function f(x) = 6x^2 −13, what is f(-3)?

Naya [18.7K]

<h3>Answer: 41</h3>

Work Shown:

f(x) = 6x^2 - 13

f(x) = 6(x)^2 - 13

f(-3) = 6(-3)^2 - 13 ... replace every x with -3; use PEMDAS to simplify

f(-3) = 6(9) - 13

f(-3) = 54 - 13

f(-3) = 41

Given r=3 and a center of (3,5)? Find the equation of the circle in standard and general form.

alukav5142 [94]

9514 1404 393

Answer:

(x -3)^2 +(y -5)^2 = 9
x^2 +y^2 -6x -10y +25 = 0

Step-by-step explanation:

The standard form equation for a circle of radius r and center (h, k) is ...

(x -h)^2 +(y -k)^2 = r^2

For radius 3 and center (3, 5), this is ...

(x -3)^2 +(y -5)^2 = 9 . . . . standard form equation

Expanding this and subtracting the constant on the right gives ...

x^2 -6x +9 +y^2 -10y +25 -9 = 0

x^2 +y^2 -6x -10y +25 = 0 . . . . general form equation

The table shows the number of candid pictures of students for the yearbook for two consecutive years. Year Number of Photos 2015

Elena-2011 [213]

Answer:

The percentage decrease in the number candid student pictures for the yearbook from 2015 to 2016 is approximately 9.3 percent

Step-by-step explanation:

The given data can be presented as follows

Year ${}$ Number of Photos

2015 ${}$ 236

2016 ${}$ 214

The percentage decrease in the number of candid pictures is give by the following formula

$Percentage \ Decrease = \dfrac{Original \ Value- New \ Value}{Original \ Value} \times 100$

Where;

Original value for the number of pictures = 236

New value for the number of pictures = 214

Substituting the values into the equation for the percentage decrease gives;

$Percentage \ Decrease = \dfrac{236- 214}{236} \times 100 = \dfrac{550}{59} \ percent\approx 9.3 \%$

The percentage decrease is approximately 9.3 percent.
