Given:
Number = -9.1
To find:
The magnitude (size) of given number.
Solution:
We know that, magnitude of a number is the absolute value of that number.
So, magnitude of -9.1 is
Because, absolute value of a number is always positive.
Magnitude of -9.1 is 9.1 because .
Therefore, the correct option is A.

Answer: It is C because if you organize the equation numerically the equation is 18x^3+30x^2+12x+10. So it is 18.
Answer:
B.
Step-by-step explanation:
The function above the x-axis looks like a parabola, so it must have an x^2 term. It also has an open circle, so it must have a > symbol.
The function below the x-axis has a closed circle, so it must have a <= symbol. It is also a 3rd degree polynomial.
Answer: B.
Answer:
311.6 cm
Step-by-step explanation:
To solve this problem, let's call:
k = Keith's height
n = nephew's height
Since the ratio is 15:7, we have
(1)
Then, Keith's height is increased by 16%, so the new height of Keith is
(2)
While the nephew's height is doubled:
(3)
We also know that Keith is now 34 cm taller than his nephew, so
(4)
Substituting (2) and (3) into (4), we get
And substituting (1),
Solving for n,
So the current height of the nephew is:
While Keith's current height is
So their total current height is
