:)
Step-by-step explanation:
hi someone help with these two questions. Thanks
Answer:
1). Option (d)
2). Options (a), (b) and (d)
Step-by-step explanation:
Question 1
a). [tex]3x^5-6x^3+9x-12x^{-1}[/tex]
Any expression with negative exponent is not a polynomial.
b). [tex]4\sqrt{x}+5[/tex]
Any expression having variable with square root is not a polynomial.
c). [tex]\frac{4x+5}{3x-1}[/tex]
Any expression having variables in the form of a fraction is not a polynomial.
d). [tex]-\frac{3}{2}x^{12}-7x^5+\frac{2}{3}x-10[/tex]
It's a polynomial.
e). [tex]-5x^{\frac{3}{2}}-7x^2+6[/tex]
Expressions having variables with square root are not the polynomial.
Therefore, Option (d) is a polynomial.
Question 2.
P(x) = (2x + 1)(5x³ - 8x + 4)
= 2x(5x³ - 8x + 4) + 1(5x³ - 8x + 4)
= 10x⁴ - 16x² + 8x + 5x³ - 8x + 4
= 10x⁴ - 5x³ - 16x²+ 4
a). Degree of polynomial = 4
True
b). P(0) = 10(0) - 5(0) - 16(0) + 4
= 4
True
c). P(-1) = 10(-1)⁴ - 5(-1)³ - 16(-1)² + 4
= 10 + 5 - 16 + 4
= 3
False
d). Coefficient of x₂ is -16.
True
e). Coefficient of x is -16
False
Therefore, Options (a), (b) and (d) are correct.

I think it is -60.71428571 percent.
Part A: The average rate of change between the 2nd and 3rd point is Select a Value Part A: The average rate of change between the 3rd and 4th point is Select a Value Part B: The average rate of change between the 2nd and 3rd point is Select a Value Part B: The average rate of change between the 4th and 5th point is Select a Value
Answer:
[tex]Rate = 6[/tex]
[tex]Rate = 10[/tex]
[tex]Rate = 18[/tex]
[tex]Rate = 162[/tex]
Step-by-step explanation:
Given
See attachment for table
Solving (a): Rate of change between 2nd and 3rd point on A
The rate of change is calculated as:
[tex]Rate = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
In table A, the 2nd and 3rd point is:
[tex](x_1,y_1) =(1,7)[/tex]
[tex](x_2,y_2) =(2,13)[/tex]
So, the average rate of change is:
[tex]Rate = \frac{13 - 7}{2 - 1}[/tex]
[tex]Rate = \frac{6}{1}[/tex]
[tex]Rate = 6[/tex]
Solving (b): Rate of change between 3rd and 4th point on A
In table A, the 3rd and 4th point is:
[tex](x_1,y_1) =(2,13)[/tex]
[tex](x_2,y_2) =(3,23)[/tex]
So, the average rate of change is:
[tex]Rate = \frac{23 - 13}{3 - 2}[/tex]
[tex]Rate = \frac{10}{1}[/tex]
[tex]Rate = 10[/tex]
Solving (c): Rate of change between 2nd and 3rd point on B
In table B, the 2nd and 3rd point is:
[tex](x_1,y_1) =(2,11)[/tex]
[tex](x_2,y_2) =(3,29)[/tex]
So, the average rate of change is:
[tex]Rate = \frac{29 - 11}{3 - 2}[/tex]
[tex]Rate = \frac{18}{1}[/tex]
[tex]Rate = 18[/tex]
Solving (d): Rate of change between 4th and 5th point on B
In table B, the 4th and 5th point is:
[tex](x_1,y_1) =(4,83)[/tex]
[tex](x_2,y_2) =(5,245)[/tex]
So, the average rate of change is:
[tex]Rate = \frac{245 - 83}{5 - 4}[/tex]
[tex]Rate = \frac{162}{1}[/tex]
[tex]Rate = 162[/tex]

On her 21st birthday, Sydney deposited $400 in a new bank account that earns 3.7% interest compounded continuously. If there are no other deposits or withdrawals, how much interest will she have earned by her 60th birthday
Answer:
$1,649.80
Step-by-step explanation:
Sydney will have earned $1293.35 in interest by her 60th birthday.
How to find interest?To solve this problem, we need to use the formula for continuously compounded interest:
A = P [tex]e^{rt}[/tex]
Where:
A is the final amount of money in the account (including principal and interest)
P is the initial principal (in this case, $400)
r is the interest rate (in this case, 3.7% per year)
t is the number of years the money is invested (in this case, 39 years)
e is the mathematical constant approximately equal to 2.718
Plugging in the values from the problem, we get:
A = $400[tex]e^{0.037 \times 39}[/tex]
Calculating this, we find that A = $400[tex]e^{1.443}[/tex] = $1693.35
Therefore, he will have earned $1693.35 - $400 = $1293.35 in interest by her 60th birthday.
