Step-by-step explanation:
anyway, without any further information about ground consistency, friction and stuff, we have to assume ideal circumstances.
so, the same energy that made the ball flying through the air makes it also bounce or roll across the ground carrying it exactly the same distance at the same time.
the distances with an ideal, reflective ground will be the same.
it is the same energy released with the same inertia.
Answer:
y = -2x + 5
General Formulas and Concepts:
<u>Algebra I</u>
Slope-Intercept Form: y = mx + b
Step-by-step explanation:
<u>Step 1: Define given</u>
y-intercept <em>b</em> = 5
Slope <em>m</em> = -2
<u>Step 2: Write function</u>
y = -2x + 5
<span>Answers:
V = (15-2x)(8-2x)x
V = 120x -46x²+ 4x³
V' = 120 -92x + 12x²
0 = 120 -92x + 12x²
x = (92±52)/24
x = 6 or 5/3
Pick x = 5/3
Volume = (15-2*5/3)(8-2*5/3)*5/3
= 90.74 inÂł
To justify x = 5/3 is the max
V" = -92 + 24x
V"(5/3) = -92 + 24(5/3) <0 negative.
Volume V(5/3) is max because the function is
concave down with V"<0.</span>
Answer: 420 different codes are possible.
Step-by-step explanation:
The number of possible codes can be given by
N = n!/(ra! × rb! × rc! × rd!)
Where;
n is the total number of letters in the code.
ra,rb,rc and rd are number of occurrence of A,B,C and D respectively
Given: n= 7, ra=3, rb=2, rc=1, rd=1.
Substituting the values, we have.
N = 7!/(3!×2!×1!×1!)
N = 5040/12
N= 420
1) Equation: y = 5x + 1
Missing Value: 51
2) Equation: y = 4x
Missing Value: 28
3) I have no idea for this one... sorry!
