Answer:
Step-by-step explanation:
let's take the rest of the money needed to be saved for purchasing the laptop be x
then,
the cost of laptop =
money saved + more money needed
so, the required expression is :
Answer:
Step-by-step explanation:
ok, so this is an infinitly repeating function, so you can write it as:
sqrt(12-x)
Although, x is also equal to sqrt(12-x), so
x = sqrt(12-x), and
x^2 = 12-x
x^2-12+x = 0
now just apply the quadratic formula and you're good
hope i helped :D
Answer:
$10.5 and $7.75
Step-by-step explanation:
Let Landon's hourly rate at babysitting job be and at water park be
now, for the first week Landon babysat for 3 hours and worked at the water park for 10 hours and made 109$.
⇒ ....(1)
Next week Landon babysat for 8 hours and worked at the water park for 12 hours and made 177$.
⇒ ....(2)
From equation (2) we get
....(3)
Substituting value of from equation (3) to equation (1) we get
Using value of x in equation (1) we get
Hence hourly rate for Landon for babysitting job is $10.5 and for water park job is $7.75
Answer:
1. 74.6° = m∠C 65.4° = m∠A a = 2.83
2. Triangle does not exist
Step-by-step explanation:
1. Use the law of sines to find m∠C
sin 40/2 = sin C/3
3sin 40/2 = sin C = .96418...
arcsin .96418... = 74.6° = m∠C
m∠A = 180 - 40 - 74.6 = 65.4°
a/sin 65.4 = 2/sin 40
a = 2 sin 65.4/sin 40 = 2.83
2. sin 95/4 = sin C/5
5sin 95/4 = sin C = 1.2452... which is impossible since the cosine of an angle is ≤ 1
