Answer:
-5, multiplicity 3; +9, multiplicity 2; -1
Step-by-step explanation:
The roots of f(x) are those values of x that make the factors be zero. For a factor of x-a, the root is x=a, because a-a=0. If the factor appears n times, then the root has multiplicity n.
f(x) = (x+5)^3(x-9)^2(x+1) has roots ...
- -5 with multiplicity 3
- +9 with multiplicity 2
- -1
The answer would be 932,000.005
The area of the shape is 84.78 square units
<h3>Area of a circle</h3>
The formula for calculating the area of a circle is expressed as:
A = πr²
where
r is the radius of a circle
Given the following
r = 6 units
pi = 3.14
Substitute
A = 3.14 * 6²
A = 113.04 square units
If the figure is 3/4 of a circle, the area of the shape will be:
A = 3/4 * 113.04
A = 84.78 square units
Hence the area of the shape is 84.78 square units

Answer:
r= 2.5 and s=3
Step-by-step explanation:
2r plus 6r equals 8r
-3s and 3s cancell eachother out
and 14 plus 6 is 20
with leaves us with
8r=20
20 divided by 8 is 2.5
now we go back to the orginal problems
2 times 2.5 is 5
14 minus 5 is 9
9 divided by 3 is 3
so s=3
but to check this all you would use r=2.5 and s=3 in the othe equsion
6 times 2.5 is 15
and -3 times 3 is -9
15-9= 6
Answer:
90 yards in 15 minutes =6 yds/min
90 yards in 9 minutes =10 yds/min
x = current rate
r = rowing rate
r + x = 10
r - x = 6 Adding both equations
2 r = 16
rowing rate = 8 yds/min
x = 2 yds/min (current rate)
