Evaluate each expression if x= 2.1 y =0.031 and z = 3.05
22. xy+z
3.1151
23. y+xz
6.436
24. x X 13.55 i y
27.424
22 and 23 are right.
I don't know about 24.
I meant -y
24. I get 28.424
Check my math.
How did you get these answers
24. Is so wrong it hurts.
To evaluate each expression using the given values, you simply substitute the values of x, y, and z into the expressions.
22. xy + z
Substitute x = 2.1, y = 0.031, and z = 3.05 into the expression:
22 * 2.1 * 0.031 + 3.05
= 1.449 + 3.05
= 4.499
So, 22xy + z evaluated when x = 2.1, y = 0.031, and z = 3.05 is 4.499.
23. y + xz
Substitute x = 2.1, y = 0.031, and z = 3.05 into the expression:
0.031 + 2.1 * 3.05
= 0.031 + 6.355
= 6.386
So, y + xz evaluated when x = 2.1, y = 0.031, and z = 3.05 is 6.386.
24. x * 13.55 * y
Substitute x = 2.1, y = 0.031 into the expression:
2.1 * 13.55 * 0.031
= 27.424
So, x * 13.55 * y evaluated when x = 2.1, y = 0.031, and z = 3.05 is 27.424.
