Jane wishes to bake an apple pie for dessert. The baking instructions say that she should bake the pie in an oven at a constant

pychu [463]

Answer:

A=152

K= -Ln(0.5)/14

Step-by-step explanation:

You can obtain two equations with the given information:

T(14 minutes) = 114◦C

T(28 minutes)=152◦C

Therefore, you have to replace t=14, T=114 and t=28, T=152 in the given equation:

$114=190-Ae^{-14k} (I) \\152=190-Ae^{-28k}(II)$

Applying the following property of exponentials numbers in (II):

$e^{a}.e^{b}=e^{a+b}$

Therefore $e^{-28k}$ can be written as $e^{-14k}.e^{-14k}$

$152=190-Ae^{-14k}.e^{14k}$

Replacing (I) in the previous equation:

$152=190-76e^{-14k}$

Solving for k:

Subtracting 190 both sides, dividing by -76:

$0.5=e^{-14k}$

Applying the base e logarithm both sides:

Ln(0.5)= -14k

Dividing by -14:

k= -Ln(0.5)/14

Replacing k in (I) and solving for A:

$Ae^{-14(-Ln(0.5)/14)}=76\\Ae^{Ln(0.5)} =76\\A(0.5)=76$

Dividing by 0.5

A=152

Which of the following shows that polynomials are closed under subtraction when two polynomials, (5x2 3x 4) − (2x2 5x − 1), are

Verizon [17]

The closure property under subtraction is shown when the correct

result from the subtraction of polynomials is also a polynomial.

Response:

The option that shows that polynomials are closed under subtraction is; <u>3·x² - 2·x + 5 will be a polynomial</u>.

<h3>How is the option that shows the closure property found?</h3>

The closure property under subtraction for the polynomials is condition

in which the result of the difference between two polynomials is also a

polynomial.

The given polynomials being subtracted is presented as follows;

(5·x² + 3·x + 4) - (2·x² + 5·x - 1)

Which gives;

(5·x² + 3·x + 4) - (2·x² + 5·x - 1) = 3·x² - 2·x + 5

Given that the result of the subtraction, 3·x² - 2·x + 5, is also a

polynomial, we have, that the option that shows that polynomials are

closed under subtraction is; <u>3·x² - 2·x + 5 will (always) be a polynomial</u>.
