Answer:
$100
Step-by-step explanation:
The amount of simple interest earned is given by the formula ...
I = Prt
where P is the amount investe, r is the annual rate, and t is the number of years.
Solving for P, we find ...
P = I/(rt) = $5.00/(0.005·10) = $100
Susan deposited $100.
Answer:
1
Step-by-step explanation:
Solve the equation for x:
3(x + 5) = -4x + 8
<em>Distribute.</em>
3x + 15 = -4x + 8
<em>Combine like terms.</em>
3x + 15 = -4x + 8
+4x +4x
7x + 15 = 8
-15 -15
7x = -7
<em>Divide both sides by 7.</em>
x = -1
The following equation has one solution, x = -1.
Answer:
x = - 
Step-by-step explanation:
Given
4x - 6 = 10x - 3 ( subtract 10x from both sides )
- 6x - 6 = - 3 ( add 6 to both sides )
- 6x = 3 ( divide both sides by - 6 )
x = 
= -
Answer:
Step-by-step explanation:
The roots of the given polynomial are: 
Since, are the roots of the polynomial, according to the factor theorem, 
would be the factors of the polynomial.
Since we have the factors of the polynomial, we can multiply them to get the desired polynomial.
Let the polynomial be represented by P(x), so
The polynomial represented by P(x) has the given roots.
Answer:
y = 9,958(0.972)^t
Step-by-step explanation:
From point to point, the difference in days is always constant (10 days), but the difference between estimated number of bees is not constant.
10000 - 7500 = 2500
7500 - 5600 = 1900
5600 - 4200 = 1600
4200 - 3200 = 1000
3200 - 2400 = 800
Therefore, the data don't fit a line.
From the other two options:
y = 9,958(0.972)^t
y = 0.972(9,958)^t
only the first one has sense, because its initial amount of bees is 9,958 (near to 10,000) and in the second option is 0.972.
