Answer:
{-14, 4}
Step-by-step explanation:
the absolute value function only makes sure that the result always has a positive sign.
so, (x + 5) must be either +9 or -9 to make the original equation true. the absolute value would turn both into +9.
so,
x + 5 = 9
x = 4
and
x + 5 = -9
x = -14
that gives us the correct set of solutions as indicated above.
Answer:
CSA = 2 * pi * r * h
Step-by-step explanation:
CSA = 2 * 22 * 7 * 12 / 7
= 2 * 22 * 12

So we can figure it out
Answer:
FV= $4,948.16
Step-by-step explanation:
Giving the following information:
Number of periods (n)= 10
Interest rate (i)= 2.15% compound interest annually
Present value (PV)= 4,000
<u>To calculate the future value, we need to use the following formula:</u>
FV= PV*(1+i)^n
FV= 4,000*(1.0215^10)
FV= $4,948.16
Answer:
Step-by-step explanation:
S A S congruence rule: Two triangles are congruent if two sides and the included angle of one triangle are equal to the two sides and the included angle of other triangle.
If two triangles are congruent by SAS, and the angle is 90, then by CPCT{corresponding part of congruent triangle) the hypotenuse of the two triangles will be congruent.
Now, as hypotenuse and one leg are congruent in both triangles, we can apply RHS congruent
