Hello,
let x the first angle
5x the second
2/3 x the third
x+5x+2/3x=180
==>20x/3=180
==>x=27 (°)
5x=5*27=135
2/3*x=2/3*27=18
27+135+18=180
Answer: 1.9166
Step-by-step explanation:
Let be the population mean.
By considering the given description, we have
n=20
s=7
Since, the population standard deviation is unknown , so we use t-test.
Test statistic :
i.e .
[Rounded to four decimal places.]
Hence, the value of the t-test statistic : 1.9166
Remember slope is
. In the graph we can just pick two points on the line to find the rise and run between. Let's say we choose (0,3) and (1,7). Between those points there is 7-3=4 rise and 1-0=1 run. So the slope is
Refer to the diagram shown below.
h = the height of the cliff.
d = the distance of the landing spot from the base of the cliff.
Assume that air resistance may be neglected, and g = 9.8 m/s².
The horizontal distance traveled in 2 seconds is
d = (1.8 m/s)*(2 s) = 3.6 m
The initial vertical velocity component is zero.
Therefore the vertical height traveled before landing on the water obeys the equation
h = (1/2)*(9.8 m/s²)*(2 s)² = 19.6 m
Answers:
The height of the cliff is 19.6 m
The distance of the landing spot from the base of the cliff is 3.6 m
Answer:
the Y intercept is (0,-2)
Step-by-step explanation:
It is the point on the graph which the line goes through the Y axis
