The scneario here expressed is an aritmetic sequence because it can be explained like this:
<span><span><span>a1</span>=35
</span><span><span>an</span>=<span>a<span>n−1</span></span>+<span>17
So all the variables can fit in and will be better explained than a geometric sequence in which you need a common ratio and that is not needed in this case</span></span></span>
Answer:
1 : 18
Step-by-step explanation:
When finding scale factor, both measurements should in same unit
Circumference of the model bell = 8 inches
1 feet = 12 inches
12 feet = 12 * 12 = 144 inches
Circumference of the actual bell = 12feet = 144 inches
Model : Actual = 8 : 144
= 8÷8 : 144÷8
= 1 : 18
Answer:
Step-by-step explanation:
Multiply the whole equation by 2
24*4x - 5*24 + 2 = 20
96x - 120 + 2 = 20
96x - 118 = 20
Add 118 to both sides
96x = 20 +118
96x = 138
Divide both sides by 96
x = 138/96 = 23/16
Identify the "a, b, c" values, find the axis of symmetry (AOS), and plug in the x-coordinate to find the y-coordinate.
a, b, c: y = ax² + bx + c → a = 2, b = -4, c = 1
AOS: x = = = = 1
y-coordinate: y = 2x² - 4x + 1 = 2(1)² - 4(1) + 1 = 2 - 4 + 1 = -1
Answer: (1, -1)
Answer:
Step-by-step explanation:
Suppose, on the contrary, a and b are both odd integers, that is:
m and n being some integers numbers.
This way you have to:
The last expression cannot be divisible by 4 since 2 is not divisible by 4. The previous conclusion leads to a contradiction, which was generated from the assumption that a and b were both odd integers. In conclusion, at least one of the two a and b should be an even integer
