This looks like scalar matrix multiplication. The idea here is to multiply the scalar 3 by each item inside the matrix.
Doing so leads to the answer [3 -12 15 -21]
Side note: I'm assuming the matrix given to you has 1 row and 4 columns.
Answer:
-62
Step-by-step explanation:
y³ – 2y (y – 5) + 13
when y = -3
y³ – 2y (y – 5) + 13
=(-3)³ – 2(-3) [ (-3) – 5] + 13 (by PEDMAS, evaluate parentheses first)
=(-27) + (6) (-8) + 13 (next do multiplication)
=(-27) + (-48) + 13
= -27 - 48 + 13
= -62
Answer:
<h3>The answer is 10.42 %</h3>
Step-by-step explanation:
The percentage error of a certain measurement can be found by using the formula
From the question
actual mass = 240 g
error = 265 - 240 = 25
So we have
We have the final answer as
<h3>10.42 %</h3>
