Answer:
148
Step-by-step explanation:
180 - 32 = 148
both angles together make 180
Cos α =
Let α = 30° ; adj = 2 ; hyp = x
∴ cos 30° =
⇒ x =
x = 2.31
Jasmine is running faster.
Since the track is 1/5 of a km and she can run 1km in 7 minutes, divide seven to get 1.4.
This means that Jasmine can run one lap in 1.4 minutes.
Since a Kyah can run 6 laps in 10 minutes, do 10 divided by 6 and the answe will be 1.6 repeating.
1.4 < 1.6 so Jasmine is faster
Answer:
- Let p be the population at t be the number of years since 2011. Then,
- The projected population of the high school in 2015=1800
- In <u>2019</u> the population be 1600 students
Step-by-step explanation:
Given: The population at Bishop High School students in 2011 =2000
Also, Every year the population decreases by 50 students which implies the rate of decrease in population is constant.
So, the function is a linear function.
Let p be the population at t be the number of years since 2011.
Then,
So at t=0, p=2000
In year 2015, t=4, substitute t=4 in the above equation ,we get
Hence, the projected population of the high school in 2015=1800
Now, put p=1600 in the function , we get
Now, 2011+8=2019
Hence, in <u>2019</u> the population be 1600 students
