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 period of the graph of 4cos(1/2x)-3 is twice as long as the period of 4cos(x)-3
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°
6 * 5 = 30 rectangle’s area
14 - 6 = 8 triangle’s base length
bh/2 for area of a triangle
8 * 5 /2 = 20 area of the triangle
20 + 30 = 50 total area
50cm^2
