What is trigonometry?Trigonometry deals with the relationship between the sides and angles of a right-angle triangle.
If cos(x) = -1/4 and tan(x) < 0
Then the value of the x will be
[tex]\begin{aligned} \cos x &= - \dfrac{1}{4}\\\\x &= \cos^{-1} \dfrac{-1}{4}\\\\x &= 104.5^o \end{aligned}[/tex]
Then the value of the sin 2x will be
[tex]\sin 2x = \sin 2*104.5^o\\\\\sin 2x = \sin 209^o\\\\\sin 2x = -0.4848 \approx 0.49[/tex]

After not studying hard enough and losing his academic scholarship, Mark needs to borrow money from 2 different banks to pay
his tuition. Bank Seven charges 12% simple interest, while First Collegiate Bank charges 10%. Mark had to borrow twice as
much from Bank Seven as he did from First Collegiate Bank. After one year, the combined interest he owed was $816. How
much did Mark borrow in total?
9514 1404 393
Answer:
$7200
Step-by-step explanation:
If x is the total amount borrowed, then 2/3x was borrowed from Bank Seven, and 1/3x was borrowed from First Collegiate Bank. The total interest owed was ...
(2/3x)(0.12) +(1/3x)(0.10) = $816
x(2/25 +1/30) = $816
(17/150)x = $816
x = $816(150/17) = $7200
Mark borrowed a total of $7200.

Mikaela is competing in a race in which she both runs and rides a bicycle. She runs 4.5 kilometers in 0.5 hour and rides her bicycle 18.75 kilometers in 0.75 hour. If she runs for 1 hour and bikes for 1 hour at the same rates as she does in the race, how far will she travel?
Answer:
25.67 km
Step-by-step explanation:
4.5 + 0.75 + 18.75 - 0.5 - 2 hrs = 25.67km
Answer:
about 35 km
Step-by-step explanation:
4.5 km divided by 0.5hour/30minutes = 6 min, 40 sec per km
18.75 divided by 0.75hour/45 minutes = 2 min 24 sec per km
60 divided 6.40 = about 9
60 divided 2.24 = about 26
26+9=35
I hope thats correct lol
What was Bear B's average speed in
m/min? No units required for answer.
Given:
Graph of positions of Bear A and Bear B.
To find:
The average speed of Bear B in m/min.
Solution:
From the graph it is clear that initial point of graph of Bear B is (0,100) and the end point is (60,2800).
The average speed of Bear B is
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\dfrac{2800-100}{60-0}[/tex]
[tex]m=\dfrac{2700}{60}[/tex]
[tex]m=45[/tex]
Therefore, the average speed of Bear B is 45 m/min.

Probability is a measure of how likely an event is to occur. Match one of the probabilities that follow with each statement of likelihood given. (The probability is usually a more exact measure of likelihood than is the verbal statement.)0 0.01 0.45 0.50 0.55 0.99 11. This event is impossible. It can never occur.A. 0B. 0.01C. 0.3D. 0.6E. 0.99F. 12. This event is certain. It will occur on every trial.A. 0B. 0.01C. 0.3D. 0.6E. 0.99F. 13. This event is very likely, but it will occur once in a while in a long sequence of trials.A. 0B. 0.01C. 0.3D. 0.6E. 0.99F. 14. This event will occur slightly less often than not.A. 0B. 0.1C. 0.3D. 0.45E. 1
Answer:
Kindly check explanation
Step-by-step explanation:
Verbal statement and associated probability:
P = 0 ; This event is Impossible event, it will never occur. It is the least value of probability an event can take.
P = 1 ; This event is certain, it will occur on every trial. It is the highest value of probability an event can have.
P = 0.6 ; very likely event, but will occur once in a while in a long sequence of trials ; very likely signifies a probability above average (0.5) though will not always occur.
P = 0.45 ; This event will occur slightly less often than not; as the probability value slightly falls below the average standardized probability value (0.5)
