Which function f (x) , graphed below, or g (x) , whose equation is g (x) = 3 cos 1/4 (x + x/3) + 2, has the largest maximum and

Leya [2.2K]

Answer:

g(x), and the maximum is 5

Step-by-step explanation:

for given function f(x), the maximum can be seen from the shown graph i.e. 2

But for the function g(x), maximum needs to be calculated.

Given function :

g (x) = 3 cos 1/4 (x + x/3) + 2

let x=0 (as cosine is a periodic function and has maximum value of 1 at 0 angle)

g(x)= 3 cos1/4(0 + 0) +2

= 3cos0 +2

= 3(1) +2

= 3 +2

= 5 !

2x - 1 = 3x + 2 3 6 A) -4 B) 2 C) 4 D) 1/4

11111nata11111 [884]

For this case we must find the solution of the following equation:

$2x-1 = 3x + 2$

If we subtract 3x from both sides of the equation we have:

$2x-3x-1 = 2$

Different signs are subtracted and the major sign is placed

$-x-1 = 2$

We add 1 to both sides of the equation:

$-x=2+1\\-x=3$

We multiply by -1 on both sides of the equation:

$x = -3$

So, the solution is $x = -3$

Answer:

$x = -3$

Wilma is thinking of a number that is divisible by both 17 and 8. What is the

svet-max [94.6K]

Answer: The smallest possible number is 136.

Step-by-step explanation:

1. You need to find the Least common multiple (LCM), which is the smallest of the common multiples of 17 and 8.

2. You can descompose 17 and 8 into primes factors. Then, you obtain:

$17=17$

$8=(2)(2)(2)=2^{3}$

3. Now, you must choose commons and no commons with the greatest exponent and multiply them. Therefore the result is:

$(17)(2^{3})=136$

$LCM=136$
