Which equation can be simplified to find the inverse of y = 2x²?
O1/y=2x²
Oy=1/2x²
O-y= 2x²
O x= 2y²
Answer:
y=1/2x²
Step-by-step explanation:
y=2x-²
y=1/2x²
The equation can be simplified to find the inverse of y = 2x² is y=1/2x², the correct option is B.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
A mathematical equation is a statement with two equal sides and an equal sign in between. An equation is, for instance, 4 + 6 = 10. Both 4 + 6 and 10 can be seen on the left and right sides of the equal sign, respectively.
We are given that;
Equation y = 2x²
Now,
To find the inverse of a function, you need to swap the x and y variables and solve for y. So, the equation that can be simplified to find the inverse of y = 2x² is x = 2y². You can simplify it by dividing both sides by 2 and taking the square root of both sides. The inverse function is y = ±√(x/2).
Therefore, by the equation the answer will be y=1/2x²

i bought a box of air head worth $7.98 there are 60 bars in the box, how much is 1 air head worth? please help
Answer:
$0.13
Step-by-step explanation:
7.98/60 = 0.133
round down to 0.13
Answer:
I believe the answer is $0.13
Step-by-step explanation:
You need to divide the price of the air heads ($7.98) by how many bars there were in the box (60). 7.98/60= 0.133
Then you round the answer to the nearest hundredth: 0.133= $0.13

A culture of yeast doubles in size every 4 hours. If the yeast population is estimated to be 3 million now, what will it be one day from now
Answer:
192,000,000
Step-by-step explanation:
Given
General form of an Exponential distribution :
y = ab^x
a = initial amount = 3000000
b = growth factor = 2
x = period = 24 / 4 = 6
y = final amount ; after one day = 24 hours ; x = 24 /4 = 6
y = 3000000(2)^6
y = 3000000 * 64
y = 192,000,000

Packets of lemonade mix
1
3
9
Is the amount of sugar you need proportional to the amount of lemonade mix you use?
Cups of sugar ∝ Number of packets
C ∝ N
C = k/N
k = C/N
a) For
1/3 cups of sugar and 1 packet of Lemonade mix
1/3 ∝ 1
1/3 = 1k
k = 1/3/1
k = 1/3
b) For
1 cups of sugar and 3 packets of Lemonade mix
1 ∝ 3
1 = 3k
k = 1/3
k = 1/3
c) For
3 cups of sugar and 9 packets of Lemonade mix
3 ∝ 9
3= 9k
k = 3/9
k = 1/3
Therefore, Yes, the amount of sugar you need proportional to the amount of lemonade mix you use. This is because the value is k is the same

Emily walked around 2 parks. One measures 54 feet by 38 feet and other measure 32 feet by 22 feet. How much did she walk?
Answer:
292 feet
Step-by-step explanation:
If Emily walked round the two rectangular parks, she walked round the perimeter of the parks.
the total distance she walked can be determined by calculating the perimeter of each of the park and adding the perimeters together
Perimeter of a rectangle = 2 x ( length + breadth)
Perimeter of the first park = 2 x (54 ft + 38 ft) = 184 ft
Perimeter of the second park = 2x (32 + 22) = 108 ft
Sum of the perimeters = 184 ft + 108 ft = 292 ft

A quadratic pattern has a second term equal to 1,a third term equal to -16 and a fifth term equal to -14
1.1.1.calculate the second difference of this quadratic pattern
1.1.2.hence or otherwise,calculate the first term of term
Answer:
1.1.1. The common difference is 12
1.1.2. The first term is 30
Step-by-step explanation:
1.1.1. The given quadratic pattern is presented as follows;
The 2nd term = 1
The 3rd term = -16
The 5th term = -14
Let 'd' represent the second difference, we have;
1 + 2d + a = -16
2·d + a = -16 - 1 = -17
2·d + a = -17...(1)
-16 + 3d + a + 4d + a = -14
7·d + 2·a = -14 + 16 = 2
7·d + 2·a = 2...(2)
Making 'a' the subject of both equation (1) and (2) gives;
a = -17 - 2·d
a = 1 - 7/2·d
∴ -17 - 2·d = 1 - 7/2·d
(7/2)·d - 2·d = 1 + 17
(3/2)·d = 18
d = (2/3) × 18 = 12
The common difference, d = 12
a = -17 - 2·d = -17 - 2 × 12 = -41
1.1.2. Let 'x' represent the first term, we have;
x + a + d = 1
x = 1 - (a + d)
x = 1 - (-41 + 12) = 30
The first term, x = 30
