Answer: Y= X+4•2
Word form: Y equals X plus 4 times 2
Take half of the coefficient of x: It is 3, and half that is 3/2.
Then <span>x^2+3x=6 becomes:
</span><span> x^2+3x + (3/2)^2 =6 + (3/2)^2, and
(x+3/2)^2 = 6 + 9/4
You were not asked to solve the equation, but why not do it for the practice?
</span>Solve (x+3/2)^2 = 6 + 9/4 for x. There will be 2 values.
C) 7 pounds 10 ounces 7 5/8
3 ponds + 4 pounds = 7 pounds
8 ounces + 2 ounces = 10 ounces
16 ounces in a pound
7 pounds 10/16 ounces
reduce '10/16' to '5/8'
<u>Given</u>:
The diameter of the circle P is 30 cm.
The radius of the circle P is 15 cm.
The measure of ∠RPS is 125°
We need to determine the arc length of QR.
<u>Measure of ∠QPR:</u>
The angles QPR and RPS are linear pairs.
Thus, we have;

Substituting the values, we have;


Thus, the measure of ∠QPR is 55°
<u>Arc length of QR:</u>
The arc length of QR can be determined using the formula,

Substituting
and r =15, we get;



Thus, the arc length of QR is 14.4 cm.
Hence, Option d is the correct answer.
