Since you gave no parenthesis: Remember to follow PEMDAS. Note that anything with the power of 0, the answer will become 1
10^0 = 1
8 x 1 = 8
8 is your answer

Answer: The radius is
r
=
3
.
Explanation:
If the point
(
−

)
belongs to the circle
(
x
+
3
)
2
+
(
y
+
1
)
2
−
r
2
=
0
then its coordinates must verify that equation. That is, if we substitute in the equation of the circle
x
by
−
3
and
y
by
2
we must obtain a true equality. Then, it is enough to clear
r
of that equation:
(
−

−
r

,
then:
r
=
√
9
=
3
.
(Remember
r
is a distance, then it's always a positive number).

Answer:
Not similar
Step-by-step explanation:
Similar triangles have
- corresponding angles are congruent
- corresponding sides are in proportion
From the diagram you can see that these two triangles have one pair of congruent right angles (with the measure of 90°), but the rest angles are not congruent (one triangle has angles with the measures 60° and 30° while the other triangle has angles with the measures 45° and 45°).
So, these triangles are not similar.
Answer:
75% increase
Step-by-step explanation:
Given:
Number of missed days of work before the management change = 4
Number of missed days of work after the management change = 7
So, increase in the number of missed days of work is given by subtracting the old number from the new number and is equal to:
Increase in missed number of days = 7 - 4 = 3 days
Now, the percent of this increase is calculated by dividing the increase by the old number and then multiplying the result by 100.
Percent of increase is given as:
So, there is a 75% increase in the number of missed days of work after the change in the management.
