Answer:

If f(−x) = −f(x), then the graph of f(x) is symmetrical with respect to . A function symmetrical with respect to the y-axis is called an even function. A function that is symmetrical with respect to the origin is called an odd function.

The sides of a triangle have lengths of x, x + 5, and 25. If the longest side is 25, which of the following values of x would ma

Amiraneli [1.4K]

In a right angle, the sum of the squares of the two shorter sides is equal to the square of the longest side.
Here, the longest side is 25, the shorter sides are x and x+5.

$x^2+(x+5)^2=25^2 \\
x^2+x^2+10x+25=625 \\
2x^2+10x+25=625 \ \ \ |-625 \\
2x^2+10x-600=0 \ \ \ |\div 2 \\
x^2+5x-300=0 \\
x^2+20x-15x-300=0 \\
x(x+20)-15(x+20)=0 \\
(x-15)(x+20)=0 \\
x-15=0 \ \lor \ x+20=0 \\
x=15 \ \lor \ x=-20
$

The length of a side must be a positive number, so x=15.
The answer is C.

PLEASE HELP ILL GIVE BRAINLIEST

Answer:

3.7m/s^2

Step-by-step explanation:

T is given as 3.27 seconds

L= 1m

we have to find g just put values in given formula

3.27s=2pi(sqrt(1m/g))

3.27s/2pi=(sqrt(1m/g))

0.520s=(sqrt(1m/g))

Taking square on both side to eliminate square root

0.27085s^2=1m/g

Multiply with g on both sides

0.27085 s^2*g=1m

Divide both sides with 0.27085

g=1m/0.27085s^2

g=3.7m/s^2

C + (4 - 3c) - 2 = 0

Basile [38]

C + (4 - 3c) - 2 = 0
c + 4 - 3c - 2 = 0
c - 3c + 4 - 2 = 0
 -2c + 2 = 0
 - 2 - 2
 -2c = -2
 -2 -2
 c = 1
