Step-by-step explanation:
y = 2kx², where k is a real constant.
We have:
2k(1)² - 2k(3)² = 32 or 2k(3)² - 2k(1)² = 32.
=> 2k - 18k = 32 or 18k - 2k = 32
=> -16k = 32 or 16k = 32
=> k = -2 or k = 2.
When x = -2,
y = 2(-2)(-2)² or y = 2(2)(-2)².
=> y = -16 or y = 16.

Answer: Choice A</h3>
2 models divided into 100 parts. Left: 68 are shaded gray. Right: 68 are shaded gray.
=====================================================
Explanation:
Consider the problem of 0.68 of 1, in other words 0.68*1 or simply 0.68
The number 0.68 is 68/100 or 68 over 100. We can have a 10 by 10 grid of tiny squares. Shade in 68 of them to represent 0.68 aka 68 hundredths.
So you'd have 6 full rows shaded (to account for 0.60 so far) and then an additional 8 squares in the seventh row (adding on 0.08 to get 0.60+0.08 = 0.68)
All of this is for one square. Double this process and you'd get 0.68*2 to represent the value 1.36
In total, 2*68 = 136 squares are shaded out of 2*100 = 200 squares total.
Answer:
x=118
y=37
Step-by-step explanation:
Since the lines are parallel:
Alternate Exterior angles are congruent, so x=118.
Linear pairs are supplementry, so y+25+118=180.
y+25=62
y=37.

Answer:
When we know all 3 sides we use the law of cosines
a = 47
b = 11
c = 38
cos (A) = (b^2+c^2-a^2) / (2bc)
cos (A) = -0.7703349282
Angle A = 140.38
cos (B) = (a^2 + c^2 -b^2) / (2ac)
cos (B) = 0.9888017917
Angle B = 8.5826 degrees
cos (C) = (a^2 + b^2 -c^2) / 2ab
cos (C) = 0.8568665377
cos (C) = 31.033 degrees
Angle W would be the smallest angle so it equals
31.033 degrees or rounded to nearest tenth
31.03
Step-by-step explanation:
What is the mean,median and mode and range of 0,0,3,3,4,5,5,7,7,7,7,7,10
dmitriy555 [2]
Mean: 5.6 (add up all the numbers and divide by the number of terms in the set)
Mode: 7 (the number that is most commonly repeated within the set)
Median: 6 (the number that is in the middle of the set)
Range: 9 (the difference between the smallest and largest number in the set)
