Answer:

Statement: Reason:

ΔNQM and ΔNQP are right triangle Definition of a right triangle

SinM = h/p and SinP = h/m Definition of sine ratio

p sin M = m sin P Substitution property of equality

p sin M / pm = msinP / pm Division property of equality.

How do you Express (x+1)(2x+2) as a trinomial

Furkat [3]

Answer:

$2x^{2} + 4x +2$

Step-by-step explanation:

Multiply (x + 1) by (2x + 2).

x × 2x is $2x^{2}$

x × 2 is 2x

1 × 2x is 2x

1 × 2 is 2

$2x^{2}$ + 2x + 2x + 2 = $2x^{2} + 4x +2$

If 150 grams of a radioactive isotope are present at 2:00 PM and 10 grams remain at 6:00 PM (the same day), what is the half-lif

pogonyaev

Initial amount, $A_o=150\ g$ .

Final amount, $A =10\ g$ .

Time taken, t = 6:00 - 2:00 = 4 hour.

We know,

$A=A_o(\dfrac{1}{2})^{\dfrac{t}{h}}\\\\10 = 150 \times \dfrac{1}{2}^{\dfrac{4}{h}}\\\\2^{\dfrac{4}{h}}=15\\\\\dfrac{4}{h}= log_215\\\\h = \dfrac{4}{log_215}\\\\h = 1.024 \ hours$

Therefore, the half-life of the isotope is 1.024 hours.

Hence, this is the required solution.
