What should be added to a²-2ab+b² to get a²-ab-2b²

dybincka [34]

SOLUTION:

what should be added to a²-2ab+b² to get a²-ab-2b²

let the added no is P

$\pmb{P+(a^2-2ab+b^2)=(a^2-ab-2b^2) }$

$\pmb{P=(a^2-ab-2b^2)-(a^2-2ab+b^2) }$

$\pmb{P=a^2-ab-2b^2-a^2+2ab-b^2 }$

$\pmb{P=ab-3b^2 }$

$\therefore{\pmb{ab-3b^2 }}$ should be added to a²-2ab+b² to get a²-ab-2b²

In triange ABC, AB=5 and AC=14. Find The measure of angle c to the nearest degree

Temka [501]

Answer:

The answer is ∠C= 20 degree

Step-by-step explanation:

The answer is ∠C= 20 degree

We have given:

AB= 5

AC = 14

and we have to find ∠c to the nearest degree.

So,

We know that:

tan(C)= AB/AC

tan(C)= 5/14

tan(C)= 0.3571

C=20 degree

Thus the answer is ∠C = 20 degree ....

The table shows the value of an account x years after the account was opened. Based on the exponential regression model, which i

lana66690 [7]

Answer:

Correct choice is B

Step-by-step explanation:

The exponential regression model can be written as exponential function

$y=a\cdot b^x.$

Then

$5,000=a\cdot b^0=a,\\ \\5,510=a\cdot b^2\Rightarrow 5,510=5,000\cdot b^2,\\ \\b^2=\dfrac{5,510}{5,000}=\dfrac{551}{500}\Rightarrow b\approx 1.05.$

Thus,

$y=5,000\cdot (1.05)^x.$

When $x=12,$ you get

$y(12)=5,000\cdot (1.05)^{12}\approx \$8,980.$
