Answer:
θ = 83°
Step-by-step explanation:
For acute angles, the sine of an angle is the cosine of its complement, and vice versa.
__
sin(θ) = cos(90° -θ) . . . . relation between sine and cosine
sin(θ) = cos(7°) . . . . . . . . given
90° -θ = 7° . . . . . . . . . matching arguments of cos( )
θ = 83° . . . . . . . . . add θ -7° to both sides

Answer: 13%
Step-by-step explanation:
The formula to find the simple interest is given by :-
, where P is the principal amount, r is rate of interest () in decimal and t is the time ( in years).
Given : P = $19,100 , I=$9932.00 and t= 4 years
Substitute all the above values in the formula , we get
In percent , 
Hence, the rate of interest = 13%
Answer:
First equation : 3, 0, -3, -6
Second equation : 2, 2.5, 3, 3.5
Step-by-step explanation:
What the first equation is basically saying is subtract 3 each time.
What the second equation is basically saying is add 0.5 each time.
Then we just add/subtract to find the first four terms.
