your answer is

b = 15 pi

length of ypx = circumfrance of circle - 1/4 of circumfrance of circle

= 2pi r - 2pi r/4 = 6 pi r / 4 = 3 pi r / 2

= 3 pi × 10/2 = 15 pi

Answer:

b. 15π m

Step-by-step explanation:

The formula for the arc length (s) of a circle is

s = rθ

Data:

r = 10 m

Calculations:

The smaller angle is π/2.

The angle θ subtending XPY is 2π - π/2 = (3π)/2.

s = rθ = 10 × (3π)/2 = 15π m

The length of XPY is 15π m.

Rewrite the expression $6j^2 - 4j 12$ in the form $c(j p)^2 q$, where $c$, $p$, and $q$ are constants. What is $\frac{q}{p}$

solniwko [45]

$Rewrite the expression 6j^2 - 4j + 12$ in the form $c(j + p)^2 + q$, where $c$, $p$, and $q$ are constants. What is $\frac{q}{p}$$

The ratio of $\frac{q}{p}$ = - 34

How to solve such questions?

Such Questions can be easily solved just by some Algebraic manipulations and simplifications. We just try to make our expression in the form which question asks us. This is the best method to solve such questions as it will definitely lead us to correct answers. One such method is completing the square method.

Completing the square is a method that is used for converting a quadratic expression of the form $ax^{2} + bx + c$ to the vertex form

$a(x - h)^{2} + k$ . The most common application of completing the square is in solving a quadratic equation. This can be done by rearranging the expression obtained after completing the square: $a(x + m)^{2} + n$ , such that the left side is a perfect square trinomial

$6j^2 - 4j +12$

= $6(j^2 - \frac{2}{3} j )+12$

= $$6(j^2 - \frac{2}{3} j + \frac{1}{9} )+\frac{102}{9}$ (Completing Square method)

= $6( j- \frac{1}{3} )^{2} + \frac{34}{3}$

On comparing with the given equation we get

p = - $\frac{1}{3}$ and q = $\frac{34}{3}$

∴ $\frac{q}{p}$ = $\frac{\frac{34}{3} }{\frac{-1}{3} }$

= - 34

Find the value of x. Express your answer in simplest radical form

klemol [59]

Since x=x, this is an isosceles right triangle. By the Pythagorean Theorem:

h^2=a^2+b^2 (the hypotenuse squared is equal to the sum of the squared sides)

5^2=x^2+x^2

25=2x^2

2x^2=25

x^2=25/2

x=√(25/2)

x=5/√2 now if we rationalize the denominator...

x=(5√2)/(√2√2)

x=(5√2)/2
