Answer:
60 ft^2
Step-by-step explanation:
This is a problem where you calculate the area of a rectangle A=bh. b=10 and h=6 so A=6*10 or 60 ft^2
Answer:
y = -8x + 12
Step-by-step explanation:
Slope intercept form: y = mx + b
m ---> Slope & b ----> y-intercept
8x + y = 12
Subtract 8x from both sides
y = -8x + 12
Answer:
The answer is 4.
Step-by-step explanation: To get the variable you do the opposite operation. So for this question you would do the opposite of subtraction which is addition. So you would add 5 to -1 and get 4.
Answer: There will 486 bacteria in 31 hours.
Step-by-step explanation:
The population decay in bacteria is exponential.
Exponential function : , where A = initial population, b multiplication decay factor, t= time:
As per given:
Initial population:
After 36 hours, population =
Divide both sides by 120,000 we get
Taking natural log on both sides , we get
At x= 31,
Hence, there will 486 bacteria in 31 hours.
The distance of the bird from the ground will be given by:
tan θ=opposite/adjacent
θ=50°
opposite=h
adjacent=12 ft
plugging in the values in the formula we get:
tan 50=h/12
thus
h=12tan50
h=14.301 ft
=14.3 ft
