Answer:
sin A = 13/85
Step-by-step explanation:
Opposite Angle A is side BC, of length 13. The length of the hypotenuse is 85. The sine function is defined as the ratio opp/hyp. In this problem that ratio is
opp
------ = sin A = 13/85
hyp
We use the inverse sine function arcsin x to determine Angle A:
A = arcsin 13/85 = 8.8 degrees
I do not have a Inspire calculator with me at the time. But I do have the equation you can enter into Solve systems (systems of equations or whatever they call it )
x=touchdowns
y=field goals
x+y=35
7x+3y=193
once you get the results x will still stand for touchdowns and y stands for field goals, and there's your answer.
hoped I helped a little.
Answer:
f(x) = ($23/week)(x)
Step-by-step explanation:
Hello!
Let's determine the unit rate. I'd suggest finding the cost per week, rather than the weeks covered by a certain amount of money.
Then:
$115
-------- = $23 per week
Then the amount spent as a function of the # of weeks would be:
f(x) = ($23/week)(x)
5 wk
