H=how far up from the ground does the ladder touch the building
h/30=sin 25°
h=30 sin 25°
h=12.7 decimeters(1 decimal place)
Answer: The height that the ladder touch the building far up from the ground is 12.7 decimeters.
Answer:
the required matrix is can be given as
Answer:
ANSWER = −6x^5 +9x^4 − 9x^3
Step-by-step explanation:
Let's simplify step-by-step.
(−3x^3) (2x^2 + 3) + 9x^4
Distribute:
=(−3x^3) (2x^2) + (−3x^3) (3) + 9x^4
=−6x^5 + − 9x^3 + 9x^4
Answer:
= −6x^5 +9x^4 − 9x^3
Answer:
6902
Step-by-step explanation:
Total milk produced in 290 days = 11.9 x 290 = 3451 litres
If 1 bottle has a capacity of 0.5l, the number of bottles needed = 3451 / 0.5 = 6902 bottles
Answer:
Step-by-step explanation:
The equation for exponential decay function is given as:
where:
D(t)= difference in temperature t=time
r=rate of change
a =initial value of the temperature
From the given problem:
Initial Temperature,a=50°C
Rate of Decay,r=
Therefore the function for the difference in temperature is given as:
We can convert 
to decimal and write the function as:
