Answer:
q(x) = 0.005 (x - 40)∧2 + 70
Step-by-step explanation:
If you mean with "up" that function is translated along the y axis
in that case the correct answer is:
q(x) = 0.005 (x - 40)∧2 + 70
God with you!!!
3x+2y=50
x+y=19
x=12, y=7
12 jumps, 7 "raise the roof"s
Answer:
The number of coins is missing, so I looked for a similar question:
Darla counted 472 pennies, 319 nickels, 436 dimes, and 271 quarters
Darla can make:
9 rolls of pennies (worth $4.50)
7 rolls of nickels (worth $14)
8 rolls of dimes (worth $40)
<u>6 rolls of quarters (worth $60)</u>
total amount of money = $118.50
Answer:
150.51 dB
Step-by-step explanation:
Data provided in the question:
decibel level of sound at 161 km distance = 180 dB
d₁ = 161 km
d₂ = 4800 km
I₁ = 180 db
The formula for intensity of sound is given as:
I = 
and the relation between intensity and distance is given as:
I ∝ 
or
Id² = constant
thus,
I₁d₁² = I₂d₂²
or

therefore,
I = 
or
I = 
or
I = 20 × (-1.474)
or
I = -29.49
Therefore,
the decibel level on Rodriguez Island, 4,800 km away
= 180 - 29.49
= 150.51 dB
