Answer:
Step-by-step explanation:
1) Vertex form of a quadratic equation is y=a(x-h)2+k, where (h,k) is the vertex of the parabola.
2) The vertex of a parabola is the point at the top or bottom of the parabola.
3) 'h' is -6, the first coordinate in the vertex.
4) 'k' is -4, the second coordinate in the vertex.
5) 'x' is -2, the first coordinate in the other point.
First, 1/2 of an hour is 30 minutes. Well, how many 30 minutes are in an hour? 2, because 2*30 = 60.
So Brenda finish 1/3 of the bracelet in 30 minutes. We would just do...
(1/3)*2 = 2/3
Brenda can finish 2/3 of a bracelet in 1 hour.
Answer:
Option (D) is correct.
Step-by-step explanation:
In a triangle BCD , with b, c, d as the sides of triangle.
Sine rule states when we we divide side b by the sine of angle B then it is equal to side c divided by the sine of angle C and also equal to side d divided by the sine of angle D.
Using Sine rule,

Consider the first and third ratio,

Substitute the values of d = 3 , b= 5 and ∠D=25°

Thus, Measure of angle B is 45 and 135 as sinB is positive is first and 2nd quadrant.
Thus, option (D) is correct.
