Answer:
B
Step-by-step explanation:
-t²+4t+5=0
t²-4t-5=0
t²-5t+t-5=0
t(t-5)+1(t-5)=0
(t-5)(t+1)=0
t=5,-1
when t=0,d=5
actual time it it is in air=5-1=4 seconds.
Answer:
There are 24 total outcomes.
Step-by-step explanation:
First, calculate the probabilities. Assuming this die is six-sided.
Probabilty of rolling a number on the wheel: 1/4, 4 total possibilities.
Probability of rolling a number on the die: 1/6, 6 total possibilities.
(1/4) * (1/6) = (1/24)
This shows 24 total outcomes. For extra understanding, this is shown below.
Spinner 2, Die 1
Spinner 2, Die 2
Spinner 2, Die 3
Spinner 2, Die 4
Spinner 2, Die 5
Spinner 2, Die 6
Repeat this for spinner 3, 4, and 5. This shows 6 * 4 or 24 total outcomes.

Answer:
11.9 cm
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you of the relation between the side opposite the angle (BC) and the hypotenuse (14 cm).
Sin = Opposite/Hypotenuse
sin(58°) = BC/(14 cm)
BC = (14 cm)×sin(58°) . . . . . multiply by the denominator
BC ≈ 11.9 cm
You can say 2.75j - 1.5j = 1.25j and 2.25+3 = 5.25 so now you have :
1.25j + 5.25 and thats simplify :)))
i hope this is helpful
have a nice day
