Answers

Answer:

Option D is right.

Step-by-step explanation:

Given are four statements and we have to find which one is true.

A) 15 is not a perfect square and hence square root of 15 is not rational. Incorrect.

B) While 15 has irrational root 0.0001 is the square of 0.01 hence the square root of second is rational hence incorrect

C) Since 15 is not a perfect square and hence square root of 15 is not rational. Incorrect

D) The square root of 15 is irrational and the square root of 0.001 is rational.

is the only correct option

Consider circle H with a 3 centimeter radius. If the length of minor arc RS is 5/2π, what is the measure of ∠RST? Assume that chords RS and TS are congruent.

Answers

Given:
Radius = 3 cm
length of minor arc = 5/2π

length of the minor arc = 2 π r (x/360°)
5/2π = 2 π r (x/360°)
5/2 * 3.14 = 2 * 3.14 * 3 (x/360°)
5/6.28 = 18.84 (x/360°)
6.28(5/6.28) = 6.28(18.84)(x/360°)
5 * 360° = 118.32x
1800 / 118.32 = x
15.21 = x

Write "P (x) = -36x^2 + 900x - 1584" in standard vertex form, help please!

Answers

y = a(x – h)2 + k, where (h, k) is the vertex;

in our case, P(x) = a $(x + b/2a)^(2) -$ Δ/4a ;

a = -36; b = 900; c = -1584;

b/2a = 900/-72 = -12.5;

Δ = $b^(2) -$ 4ac = 810000 - 144*1584 = 581904 => -Δ/4a = 4041;

P(x) = (-36)(x - 12.5)^2 + 4041, where (12.5 , 4041) is the vertex;
