When you have f(3), that means X is equal to 3.

The problem states if x <-3 then f(x) would be -2.
If x is between -1 and -3, then f(x) would be 4x.
 If x is greater than -1, f(x) would be x^2.

3 is greater then -1, so f(3) would be x^2, now replace x with 3 to get 3^2, which equals 9.

f(3) = 9

Design a logic circuit to take input signals P, Q, and R and output a 1 if , and only if, P and Q have the same value and Q and
svet-max [94.6K]

Step-by-step explanation:

We have 3 given inputs namely P, Q, R and we have to draw a logic circuit which will give the output 1 if , and only if, P and Q have the same value and Q and R have opposite values.

So, first of all we make a truth table for this

P        Q        R        Output(Y)

0        0        0           0

0        0         1           1

0         1        0           0

0         1         1           0

1         0        0          0

1          0        1           0

1          1        0           1

1          1         1           0    

From the truth table we can see that the output, Y can be given by

Y=\bar{P}\bar{Q}R+PQ\bar{R}

So, the logic circuit for the given logic equation can be drawn as shown fig.

I MEEED HELPPP PLEASEEEEEE HELPPPPP PLEASE SOMEONE IM BEGGING UUUUU
Stels [109]

Answer:

x= 10°

Step-by-step explanation:

BWN = BRN (W=R)

56+ (5x-16) +90 =180 {triangle BNW} [angles in a triangle add up to 180] ( properties of a kite)

5x = 180 - (56 + 90 - 16)

5x = 180 - 130

5x = 50

x =50/5

x = 10°
