0.00000604 = 6.04 × 10 ⁻⁶
Numbers in scientific notation get written in the form 1.23... × 10ⁿ, so it's a matter of counting how many times you multiply or divide by 10 in order to move the decimal point to the right position.
The number 0.00000604 has 3 significant digits, so you want to end up with 6.04, and to do that you need to move the decimal point 6 places to the right:
0.00000604
= 0.0000604 × 10 ⁻¹
= 0.000604 × 10 ⁻²
= 0.00604 × 10 ⁻³
= 0.0604 × 10 ⁻⁴
= 0.604 × 10 ⁻⁵
= 6.04 × 10 ⁻⁶
The toll to a bridge is 2.50. A three-month pass costs $12.00 and reduces the toll to $0.50. A six month pass $37 and permits crossing the bridge for no additional fee. How many crossing per three month period does it take for the three month pass to be the best deal.
c=number of crossings; Q=quarterly pass; S=semi-annual pass; P=pay as you go
P=$2.50c
Q=$12+$0.50c
S=$40
Compare single pay and quarterly ticket:
$2.50c=$12+$0.50c Subtract $0.50c from each side
$2.00c=$12 Divide each side by $2.
c=6 6 crossings is the break even for single pay and quarterly ticket: more crossings favor the ticket.
Compare quarterly and semi-annual tickets:
3 month pro-rated cost of semi annual ticket=$20
$20=$12+$0.50c Subtract 12 from each side
$8=$0.50c Divide each side by $0.50
16=c The break=even point between quarterly and semi annual tickets is 16 crossings per 3 months. More than this favors the semi annual ticket.
ANSWER: The three month pass is the best deal if you cross between 6 and 16 times during the three month period.

Which is the graph of the exponential function y = 0.5(0.5)x?
Answer:
The answer is B
Step-by-step explanation:
2y + 8y - 20 = 5 (y -2) simplify
Answer:
y=2
Step-by-step explanation:
2y + 8y - 20 = 5 (y -2)
Combine like terms
10y -20 = 5(y-2)
Divide by 5
10y/5 -20/5 = 5/5(y-2)
2y -4 = y-2
Subtract y from each side
2y-y -4 =-2
y -4 = -2
Add 2 to each side
y-4+4 =-2+4
y =2
Answer:
[tex]2y + 8y - 20 = 5(y - 2) \\ 10y - 20 = 5y - 10 \\ 5y = 10 \\ y = 2 \\ thank \: you[/tex]

An elevator is at a height of 200 feet. It is descending at a constant rate of 8 feet per second. What is the height, in feet, of the elevator after 13 seconds??
Answer:
304
Step-by-step explanation:
8 x 13 = 104
+200
304
Answer:
96feet
Step-by-step explanation:
U want to find displacement
So
Displacement = velocity x time
Velocity = - 8 feet/s ( negative bcuz going down)
Time = 13
Displacement = - 8 x 13
= - 104
Therefore
200 - 104 = 96feet

What is the inverse of the function f(x) = 2x – 10?
O h(x) = 2x-5
Oh(x) = 2x + 5
Oh(x) =
Ix-5
x) = {x+5
Oh(x) =
If h(x) is the inverse of f(x), then by definition of inverse function, we have
f(h(x)) = x
By definition of f(x), composing f with h gives
f(h(x)) = 2 h(x) - 10
Solve for h(x) :
x = 2 h(x) - 10
2 h(x) = x + 10
h(x) = (x + 10)/2
h(x) = x/2 + 5
So... whichever option most closely resembles this is the correct one. It's hard to tell exactly which one that would be.

solve for x. 3(x-15)=30
help!!!!
Answer:
[tex]3(x - 15) = 30 \\ multiply \: in \: between \: brcket \\ 3x - 45 = 30 \\ 3x = 30 + 45\\ 3x = 75 \\ x = \frac{75}{3} = 25 \\ thank \: you[/tex]
Answer:
x is 25
Step-by-step explanation:
3 ( x - 15) = 30
3x - 45 = 30
3x = 30 + 45
3x = 75
x = 25

0 If 3x+ 11 = 86-5 the x = ?
Answer: x = 70/3
Step-by-step explanation:
Given equation
3x + 11 = 86 - 5
Simplify by subtraction
3x + 11 = 81
Subtract 11 on both sides
3x + 11 - 11 = 81 - 11
3x = 70
Divide 3 on both sides
3x / 3 = 70 / 3
[tex]\boxed{x=\frac{70}{3} }[/tex]
