Answer:
Undefined
Step-by-step explanation:
The formula for slope is [ y2-y1/x2-x1 ]
5-7/3-3
-2/0
Since the denominator is 0, the slope is undefined.
Best of Luck!
Answer:
w=63, x = 86, y=38 and z = 25 degrees
Step-by-step explanation:
w + 117 = 180
so w = 180 - 117 = 63 degrees.
x = 180 - 63 - 31 = 180 - 94
= 86 degrees
y = 180 - 86 - 56 = 180 - 142
= 38 degrees
z = 180 - 117 - 38 = 180 - 155
= 25 degrees
Answer:
Step-by-step explanation:
A regular polygon is defined to be a convex polygon with congruent sides and congruent angles.
Convex means that all interior angles are less than 180 degrees. However, if all interior angles are equal, the polygon has to be convex.
The rate of 28,000% per month is extremely big. I believe
the correct monthly rate is 2.8% (correct me if I am wrong though). Next time
kindly check the given values.
Rate is expressed in a factor of:
(1 + r)^n
where r is the rate and n is the number of months
First we calculate for the rate in a year (1 year = 12
months). We know that the rate must be constant, therefore:
rate in a month = rate in a year
(1 + 0.028)^1 = (1 + r)^(1/12)
r = 0.3929
Therefore there is an increase of about 39.29% in a year.
Then we calculate for the rate in a day (1 month = 30
days). The rate must also be constant, therefore:
rate in a month = rate in a day
(1 + 0.028)^1 = (1 + r)^(30)
r = 9.21 * 10^-4
Therefore there is an increase of about 0.092% per day.
Answer:
b = 40 and -40
Step-by-step explanation:
General form of Perfect square trinomial is a 2 + 2 a b + b 2
Therefore from 16 x 2 − b x + 25 a 2 = √ 16 x 2 , b 2 = 25 , then a = ± 4 x , b = ± 5 take consideration a=4x and b=-5 (different sign), then − b x = 2 ( 4 x ) ( − 5 ) − b x = − 40 x b = 40
The perfect square is ( 4 x − 5 ) 2 = 16 x 2 − 40 x + 25 .
if we consider a=4x and b=5 (same sign), then − b x = 2 ( 4 x ) ( 5 ) − b x = 40 x b = − 40
The perfect square is ( 4 x + 5 ) 2 = 16 x 2 + 40 x + 25 .
The first solution ( 4 x − 5 ) 2 is the best solution after comparing the expression given. I hope this helps, xx .
