7 x 24 = 168 hours a week
168 x 60 = 10,080 minutes a week
10,080 x 60 = 604,800 seconds in a week
Answer:
The value of y = 70°
Step-by-step explanation:
∵ The measure of the major arc = 160 + 60 = 220°
∵ The measure of the circle is 360°
∴ The measure of the minor arc = 360 - 220 = 140°
∵ y is the angle between a chord and a tangent
∵ The chord subtended by the arc of measure 140°
∵ y is subtended by the arc of measure 140°
∵ Angle of tangent subtended by an arc,
its measure = half the measure of the subtended arc
∴ The measure of y = 1/2 the measure of the subtended arc
∴ y = 1/2 × 140 = 70°
3x(sqrt 4x+5)/4x+5
You have to multiply the numerator and denominator by sqrt 4x+5 in order to rationalize
