Answer:
8 = r
Step-by-step explanation:
69 = 9r -3
Add 3 to each side
69+3 = 9r -3+3
72 = 9r
Divide each side by 9
72 / 9 = 9r/9
8 = r
There are 36^7 different passwords available, incluiding ones that have repeated characters, are sequential characters, or are all the same letter or digit. Of these 26^7 are invalid. the probability of obtaining a valid password is
... 1 - 26^7/36^7 ≈ 0.8975
Answer:
No, he is not correct.
Step-by-step explanation:
For a linear equation, the equation is y=mx+b. The "b" is the initial value or the y intercept. He's missing that part. For example, y=2x. If you plug in 2, you won't get 8. The correct equation is y=2x+4. If you plug in 2, it'll give you the correct y value, 8.

Answer:
71.60ft
Step-by-step explanation:
Hello,
The question above requires us to use find the relationship between the angle and the length of the slide.
To solve this question, it is pertinent to get the diagram correctly so as to get the answer right.
See attached document for better illustration.
From the diagram,
We have the value of the opposite side or the triangle, and the angle of depression.
Using SOHCAHTOA,
Tanθ = opposite / adjacent
θ = 31.66°
Opposite = 46ft
Adjacent = x
Tanθ = opp / adj
Tan31.66 = 46 / x
X = 46 / tan31.66
X = 46 / 0.6166
X = 71.60ft
The height of the slide is 71.60ft
