the amount y of your friends allowances if the amount she receives is 2$ more than the amount x you receive
liberstina [14]

Hello, How are you doing today?

If your friend makes 2$ more than you do, then you must form an equation for the problem. y = amount she has, x = your amount. Therefor, it would be:

y = x + 2

If you make 6 dollars, she will make 8 and so on. Thank you, have a nice day!

Question 3 of 10 * - 3 is a factor of P(x) =*? – 73? + 158-9 O A. True O B. False
Elina [12.6K]

Given,

The expression is,

P(x)=x^3-7x^2+15x-9

If x- 3 is the factor of the given polynomial function, then on substituting the value of x = 3 in the polynomial function, it become zero.

Thus subsituting the value of x in the polynomial,

\begin{gathered} P(3)=3^3-7\times3^2+15\times3-9 \\ =27-7\times9+45-9 \\ =27+45-63-9 \\ =72-72 \\ =0 \end{gathered}

Here, the obtained value of polynomial is 0.

Hence, x-3 is a factor of the given polynomial.

Thus, option A(true) is correct.

The weights of Sarus crane chicks and hooded crane chicks H (both in grams) during the 10 days following hatching can be modeled
Katarina [22]

Answer:

  • 35.875 grams

Step-by-step explanation:

Given

<u>Functions:</u>

  • S(t) = –0.122t³ + 3.49t² – 14.6t + 136
  • H(t) = –0.115t³ + 3.71t² – 20.6t + 124  

<u>Finding the difference between S(5) and H(5)</u>

  • S(5) - H(5) =
  • –0.122t³ + 3.49t² – 14.6t + 136  - (–0.115t³ + 3.71t² – 20.6t + 124) =
  • (-0.122 + 0.115)*5³ + (3.49 -3.7)*5² - (14.6 -20.6)*5 + 136 - 124 = 35.875

Answer is 35.875 grams
