Answer:
(3) Driving in a straight line at 100 kilometers per hour
Step-by-step explanation:
let us see each at a time.
(1) Slaming on the brakes causes the speed to become 0units/sec and car comses to rest. the car experiences deceleration (negative acceleration), we can role this one out.
(2) Going from 0 to 100Kilometers per hour, speed increases from 0 to 100km/s in 10 seconds that is acceleration. we can rule this one out.
(3) Driving in a straight line with 100km/hour velocity, here we have constant velocity and there is no acceleration so in this case we are not accelerating.
Answer:
253°
Step-by-step explanation:
The central angle whose rays intercept a diameter of the circle has measure 180 deg.
m<AOD = 73 deg
m<DOB = 180 deg
m<ADB = m<AOD +m<DOB = 73 deg + 180 deg = 253 deg
The measure of an arc of a circle is equal to the measure of the central angle that subtends it.
m(arc)AOD = m<AOD = 253 deg
Answer: 253°
Answer:
x=6
b= 126
Step-by-step explanation:
8x+78 = 2x+114
8x-2x = 114-78
6x=36
x=6
--------
b=2x6+114
b= 126
Answer:
x = 19
Step-by-step explanation:
use the distributive property
3(x - 9) = 30
3x - 27 = 30
<u> +27 +27</u>
3x = 57
divide by 3
x = 19

We can solve this in a number of ways: using the point-slope formula, using trial and error or by inspection.
Using the point-slope formula:
y - y1 = m (x - x1)
y - (-3) = (-6) (x - (-2))
y + 3 = -6x - 12
y = -6x - 12 - 3
y = -6x - 15
Therefore, the answer is the first option.
