Answer:
-6.21 x 10^5
Step-by-step explanation:
The negative only comes when the numbers are in the decimal to right such as 0.1 when its on the left side it just mean positive power such as 6.0= a positive, negative power = 0.6 count how many numbers there are (6) then get the last number as the whole number and the rest are behind (-6.21) count all the numbers besides the last number (6) now that is your power so you get -6.21 x 10^5
Answer:
Step-by-step explanation:
2^2=1.75^2+3^2-2*3*1.75cos x
4=3.0625+9-10.5 cosx
10.5cos x=9-4+3.0625
10.5cosx=8.0625
cos x= 8.0625/10.5≈0.77
x≈40 degrees
Given:
The fees for a day student are $600 a term.
The fees for a boarding student are $1200 a term.
The school needs at least $720000 a term.
To show:
That the given information can be written as 
.
Solution:
Let x be the number of day students and y be the number of boarding students.
The fees for a day student are 
a term.
So, the fees for 
day students are 
a term.
The fees for a boarding student are 
a term.
The fees for 
boarding student are 
a term.
Total fees for day students and boarding student is:
The school needs at least $720000 a term. It means, total fees must be greater than or equal to $720000.
Divide both sides by 600.
Hence proved.
