Y=-4a+24
This is the answer hope that helps
Answer:
18500 is the initial value
Every year they increase by a factor of 1.03
Step-by-step explanation:
This is written in the form
y = ab^x where a is the initial value and b is the growth rate/decrease
y = (18500) (1.03)^t
The initial value is 18500
The students will increase by 1.03 - 1 = .03
The factor of increase is what they multiply by which is 1.03
Answer:
1.5 hours
I traveled farther
2 miles
Step-by-step explanation:
My speed
Speed of my friend
Time passed for both me and my friend will be equal if we start at the same time and the combined distance covered by both of us will be 24 miles. Let 
be the time taken to meet
So, we meet each other after 1.5 hours.
Distance traveled by me
Distance traveled by my friend
So, I traveled farther by 
.
B because the line over the 28 means that it’s repeating and a repeating decimal = rational number example : 27.67777777 is a rational number because it’s repeating and an irrational number would be 27.6719473637
Answer:
34
Step-by-step explanation:
x=3+√8
y =3-√8
now,
1/x^2+1/y^2
=1/(3+√8)² + 1/(3-√8)²
= [(3-√8)²+(3+√8)²] / (3+√8)²(3-√8)² [L.C.M = (3+√8)²(3-√8)² ]
=[(3-√8+3+√8)²-2(3-√8)(3+√8) ] / [(3+√8)(3-√8)]²
=[6²-2.(3²-√8² )] / (3²-√8²)² [ a²+ b²=(a+b)²-2ab]
=[36-2(9-8) ]/ (9-8)²
=[36-2.1] / 1²
=34
