What is the value of f(-2) for the given function

scZoUnD [109]

Copy down the given function:

f(x)=3•2^x

Now replace both instances of x with -2:

f(-2) = 3*2^(-2). 1

Recall that 2^(-2) is the same as ------ = 1/4

2^2

Therefore, f(-2) = 3*2^(-2) = 3*(1/4) = 3/4

Remember that exponentiation has to be carried out before multiplication. That's why I did 2^(-2) before multiplying by 3.

Four accounting majors, two economics majors, and three marketing majors have interviewed for five different positions with a la

Slav-nsk [51]

Answer:

Option c

Step-by-step explanation:

From the question we are told that:

Four accounting majors $N_a=4$

Two economics majors $N_e=2$

Three marketing majors $N_m=3$

Total Applicants N_T=9

Generally the equation for Different ways that five of these could be hired is mathematically given by

$X_5=^9P_5$

$X_5=\frac{9!}{(9-5)!}$

$X_5=15120$

Generally the equation for Different ways that Three of these could be hired is mathematically given by

$X_3=^9P_3$

$X_3=\frac{9!}{(9-5\3)!}$

$X_3=504 ways$

Option c

Are two lines parallel, perpendicular or neither 3x+7y=15 and 7x-3y=6

maw [93]

Answer:

The lines are perpendicular

Step-by-step explanation:

we know that

If two lines are parallel, then their slopes are equal

If two lines are perpendicular, then their slopes are opposite reciprocal (the product of their slopes is equal to -1)

we have

$3x+7y=15$ ----> equation A

isolate the variable y

$7y=-3x+15$

Divide by 7 both sides

$y=-\frac{3}{7}x+\frac{15}{7}$

The slope of the line A is $m_A=-\frac{3}{7}$

$7x-3y=6$ ----> equation B

isolate the variable y

$3y=7x-6$

Divide by 3 both sides

$y=\frac{7}{3}x-2$

The slope of the line B is $m_B=\frac{7}{3}$

Compare the slope of both lines

$m_A=-\frac{3}{7}$

$m_B=\frac{7}{3}$

$m_A \neq m_B$ ----> the lines are not parallel

Find the product of the slopes

$-\frac{3}{7}(\frac{7}{3})=-1$ ----> the lines are perpendicular
