IN the diagram Below AB is parallel to CD what is the value of y ? <br> picture is below

satela [25.4K]

Similar to the other question, because AB is parallel to CD, you know the 72º angle corresponds to the angle on top of y.

Because that angle above y and y together make a straight line (and a straight line measures 180º), you have
72 + y = 180

Solving that for y, you get y = 108º

${ \tt{a + 40 \degree + 30\degree = 360\degree}} \\ \\ { \tt{a + 70\degree = 360\degree}} \\ \\ { \tt{a = 360\degree - 70\degree }} \\ \\ { \boxed{ \tt{ \: \: a = 290\degree}}}$

Help please I rlly need the working out and answer :((

Answer:

1126

Step-by-step explanation:

<u>Given formula</u>:

$P_{n+1}=k(P_n+60)$

Given information:

$\textsf{Let }P_1 = \textsf{Population on March 1st 2016} =500$
$\textsf{Let }P_2 = \textsf{Population on March 1st 2017} =672$

Substitute these values into the formula and solve for k:

$\begin{aligned}P_{n+1} & = k(P_n+60)\\\implies P_2 & = k(P_1+60)\\672 & = k(500+60)\\672 & = 560k\\k & = \dfrac{672}{560}\\k & = 1.2\end{aligned}$

Substitute the found value of k into the formula:

$P_{n+1}=1.2(P_n+60)$

If:

P₁ = Population on March 1st 2016
P₂ = Population on March 1st 2017

Then:

P₃ = Population on March 1st 2018
P₄ = Population on March 1st 2019

Use the formula and the value of P₂ to find P₃ and P₄.

$\begin{aligned}P_{3} & =1.2(P_2+60)\\& = 1.2(672+60)\\& = 878.4\end{aligned}$

$\begin{aligned}P_{4} & =1.2(P_3+60)\\& = 1.2(878.4+60)\\& = 1126.08\end{aligned}$

Therefore, the prediction for the population on 1st March 2019 is 1126 tadpoles (nearest whole number).
