Answer:
b. They are at a speed of 30 mph when time begins.
Step-by-step explanation:
The y-axis represents time zero, when time begins. The curve intercepts the y-axis at y=30. Y-values on the graph represent speed in miles per hour (mph), so a y-value of 30 at the point on the y-axis represents ...
a speed of 30 mph when time begins
Answer:
C
Step-by-step explanation:
Complementary means that the angles have a sum of 90° so we can write:
m∠A + m∠B = 90° → 3x + 2 + 8x = 90
11x + 2 = 90
11x = 88
x = 8 which means that m∠B = 8x = 8 * 8 = 64°.
Supplementary means that the angles have a sum of 180° so m∠C = 180° - m∠B = 180° - 64° = 116°.

Answer:
89.0°
Step-by-step explanation:
The measure of arc CD is the same degree measure as the central angle.
To find the central angle use the right triangle.
The segment from the centre to the chord is a perpendicular bisector, thus
the third side of the triangle = 12.7 ÷ 2 = 6.35
Calculate one half of the central angle using the sine ratio and multiply by 2 for the whole central angle
sin( one- half ) =
= 
, hence
central angle = 2 × 
( ) ≈ 89.0°
Hence measure of CD ≈ 89.0°
