Answer:
6.84%
Step-by-step explanation:
we know that
In this problem
Tara's monthly income ($3,200) represent the 100%
so
using proportion
Find out what percentage represent $219
Let
x ----> the percentage that represent $219

Answer:
The property used is the commutative property.
Step-by-step explanation:
In the commutative property, the sum is the same if you reorder the numbers.
I hope this helped! :-)
Answer:
The common difference (or common ratio) = 0.75
Step-by-step explanation:
i) let the first term be = 80
ii) let the second term be = . r = 80 × r = 60 ∴ r = = 0.75
iii) let the third term be = . r = 60 × r = 45 ∴ r = = 0.75
iv) let the fourth term be = . r = 45 × r = 33.75 ∴ r = = 0.75
Therefore we can see that the series of numbers are part of a geometric progression and the first term is 80 and the common ratio = 0.75.
F(x) is continuous for all x.
Pick a point and show that f(x) is either negative or positive. Pick another point and show that f(x) is negative, if positive, or positive, if negative.
At x = 30, f(30) - 1000 = 900 + 10sin(30) - 1000 ≤ 0
Now, show at another point f(x) - 1000 is positive, and hence, there would be root between 30 and such point.
Let's pick 40.
At x = 40, f(40) - 1000 = 1600 + 10sin(40) - 1000 ≥ 0
Since f(x) - 1000 is continuous, there lies a root between 30 and 40, and hence, 30 ≤ c ≤ 40
