#2) 435+25x=875-15x
40x=440
x=11
the answer is 11 weeks.
#3) 2500(3x) for x=10
2500(3*10)
2500(30)
7500
the answer is 7500 bacteria after 10 months.
Im pretty sure this is the answer F (x) = e^2x + 1
Answer:
34 ft
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you of the relationship between adjacent and opposite sides of a right triangle and the trig function of the associated angle. Here, the relevant relation is ...
Tan = Opposite/Adjacent
tan(10°) = (height of lifeguard)/(distance from shore)
Then the distance from shore is ...
distance from shore = (height of lifeguard)/tan(10°) ≈ (6 ft)/(0.17633)
distance from shore ≈ 34 ft
Using it's concept, the probability of spinning the spinner and the arrow landing on the number 1 and then on number 2 the second time is:
D) 3/32.
<h3>What is a probability?</h3>
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
In this problem, we have that:
- For the first roll, two out of eight outcomes are 1.
- For the second roll, three out of eight outcomes are 2.
Hence the probability is given by:
p = 2/8 x 3/8 = 6/64 = 3/32.
Which means that option D is correct.
