Answer:
0.01514 or 1.5x10^-4
Step-by-step explanation:
It's already in scientific notation!
But if you wanna know how to write it generally, you would take the decimal and move it 3 spaces to the left. to get:
0.01514
Edit: Or if you looking to make it 1.5x10^-4
That would be your answer(move one place to the left!)
Hope this helps!
Answer:
Step-7.5% of bagel packages are sesame seed bagels
step by-step explanation:As in the other question, we can find the answer by doing a simple equation:
15 = x% from 200
15 = * 200
15 = 2x / ÷ 2 (both sides)
x = 7.5 [percent]
Answer:
Step-by-step explanation:
You've typed the equation incorrectly. 3^5x-1 = 3⁵x-1.
It needs to be typed as 3^(5x-1) = 7.
Answer:
1 shirt for every 6 hours
Step-by-step explanation:
42/7=6
The exponential function is :
y=ab^x
We have two points:
(1, 7.5)
(3, 16.875)
First point:
(1 , 7.5)
x=1
y=7.5
y=ab^x
7.5=ab¹
Second point:
(3 , 16.875)
x=3
y=16.875
y=ab^x
16.875=ab³
Then, always is true that.
7.5 / 16.875 = (ab) / (ab³)
7.5(ab³)=16.875(ab)
7.5ab³ / a
b²=16.875
7.5b²=16.875
b=⁺₋√(16.875 / 7.5)
b=⁺₋1.5
if b=-1.5 ⇒ 7.5=a(-1.5) ⇒a=-5
y=-5*(-1.5)^x
y=5(1.5^x)
if b=1.5 ⇒ 7.5=a(1.5) ⇒ a=5
y=5*(1.5^x)
Answer; y=5*1.5^x
