Let f(x)= x2 - 14 and g(x) = 6-X.<br> Find (fq)(7).
sleet_krkn [62]

Answer:

(fg)(7) = - 35

Step-by-step explanation:

The given functions are:

f(x) =  {x}^{2}  - 14

and

g(x) = 6 - x

We want to to find

(fg)(7)

Note that:

(fg)(x) = f(x) \times g(x)

We substitute the functions to obtain:

(fg)(x) = ( {x}^{2} -1 4 ) \times (6 - x)

We now substitute x=7, to get:

(fg)(7) = ( {7}^{2} -1 4 ) \times (6 - 7)

This implies that

(fg)(7) =( 49-1 4 ) \times (6 - 7)

(fg)(7)  = 35 \times  - 1 =  - 35

Maria works in a factory that produces new cars. She is having trouble with one of the machines. In order to work properly, the
Dovator [93]

Answer:

Maria did her job properly. Both gears are perpendicular.

Step-by-step explanation:

Recall that given vectors a and b, they are perpendicular if and only if a\cdot b =0. If a=(a_1,a_2),b=(b_1,b_2). Then a\cdot b = a_1b1_+a_2b_2.

IN our case a=(5,-1,2) and b) (1,-3,-4). So,

a\cdot b = 5\cdot 1 + (-1)\cdot(-3) + 2\cdot(-4) = 5+3-8 =0

So both gears are perpendicular.
