Hello from MrBillDoesMath!
Answer: Choice B, 3 ( x + 9) (x+3)
Discussion:
Factor 3 from each term:':
3x^2+36x+81 = 3 (x^2 + 12x +27).
As 9+3 = 12 ans 9*3 = 27 the factorizaiton is
3 ( x + 9) (x+3)
which is choice B
Thank you,
MrB
Refer to the diagram shown below.
h = the height of the cliff.
d = the distance of the landing spot from the base of the cliff.
Assume that air resistance may be neglected, and g = 9.8 m/s².
The horizontal distance traveled in 2 seconds is
d = (1.8 m/s)*(2 s) = 3.6 m
The initial vertical velocity component is zero.
Therefore the vertical height traveled before landing on the water obeys the equation
h = (1/2)*(9.8 m/s²)*(2 s)² = 19.6 m
Answers:
The height of the cliff is 19.6 m
The distance of the landing spot from the base of the cliff is 3.6 m
Answer:
<u>Answer</u><u>:</u><u> </u><u>w</u><u> </u><u>is</u><u> </u><u>1</u><u>.</u><u>6</u><u> </u><u> </u><u>or</u><u>. </u><u>-</u><u>5</u><u>.</u><u>6</u><u> </u>
Step-by-step explanation:
• I guess the question asks to find the value of w
• arrange the equation in a quadratic equation format. i.e; ax² + bx + c = 0
• let's solve the equation using the quadratic formular
• Substitute following the mathematical operation rules:
• split the result:
Use the equation formula b times r^h
you have find the ratio
