1) The area is 81 Units
2) the picture of the shaded region isn’t provided so I am unable to answer sorry
Answer:
x = 4
Step-by-step explanation:
Since they are parallel, we use the formula
7x = 28
x = 4
SI
$1 000 × 4 % × 10 = $400
CI
($1 000 × 1.04 ^10) - $1 000 = $1 480.24 - $1 000 = $480.24
Interest on interest only applies to Compound Interest.
Excluding year 1, which yields $40 [the same as SI] the interest on interest yields $480.24 - $40 = $440.24

Answer:
[0,1] and [-1,0]
Step-by-step explanation:
We have the function to determine consecutive values of x between which each real zero is located we have to replace the function with different values and then analyze the results.
We are going to replace the function with x=0,
Now we are going to replace with x=1,
With x=2,
Now with x=-1,
With x=-2,
We have to analyze:
We have that f(2) and f(1) have the same signs both are negatives this means that there isn't a zero between the interval [1,2].
We have that f(1) and f(0) have opposite signs this means that there is a zero between the interval [0,1].
f(0) and f(-1) have opposite signs too, then there's also a zero in the interval [-1,0].
And finally, f(-1) and f(-2) have the same signs then there isn't a zero in the interval [-2,-1]
The graph of the function shows that the answer is correct:
