Which equation can be simplified to find the inverse of y = 2x²?
O1/y=2x²
Oy=1/2x²
O-y= 2x²
O x= 2y²
Answers
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

find the surface area of the prism. 3in , 8in ,5in.
Answers
Answer:
158 in.
Step-by-step explanation:
Surface area of a prism = Area of all the faces added together
So, Face 1 & 2 = 5 x 80 = 40 x 2 = 80
Face 3 & 4 = 8 x 3 = 24 x 2 = 48
Face 5 & 6 = 5 x 3 = 15 x 2 = 30
Therefore, adding them together makes:
80 + 48 + 30 = 158 in.
A horse's paddock is triangular with a height of 76 ft and sides of 114 ft, 102 ft, and 53 ft. What is the cost of fencing around the paddock if the fencing costs $5.40 per ft?
Answers
Answer:
$1452.6
Step-by-step explanation:
To obtain the cost of fencing round a triangular paddock, we obtain the perimeter. The perimeter of a triangle is given as :
Perimeter = a + b + c ; where a, b and c are the length of the three sides of the triangle.
The perimeter of the paddock in this scenario is :
(114 + 102 + 53) feets = 269 feets ; which are the lengths of the 3 sides of the triangular paddock.
Painting Cost per feet = $5.40
Cost per feet * number of feets
$5.40 * 269
= $1452.6

A triangle has sides that are 3, 7, and squareroot 57. Is the triangle a right triangle?
Answers
Answer:
my answer is no because for a right angle triangle the sum of the squares of the other two sides is equal to the square of the longest side
3²+7²=9+49=58
(√57)²=57
57≠58 it's not a right angle triangle
assume the sides to be a,b and c
a=3 b=7 c=√57
by Pythagoras theorem
a²+b²=c²
3²+7²=√57²
but 58≠57

Which best proves why the expressions 4 (x + 3) + 2 x and 6 (x + 2) must be equivalent expressions? When x = 3, both expressions have a value of 30. When x = 5, both expressions have a value of 42.
Answers
Answer:
The answer is choice first which is "When x = 3, both expressions have a value of 30".
Step-by-step explanation:
Given:
First expression: [tex]4(x+3)+2x[/tex]
Second expression: [tex]6(x+2)[/tex]
Through the question when we substitute x=3 into its first equation so we get:
[tex]\to 4(3+3)+2(3) \\\\ \to 4\times (6)+6\\\\ \to 24+6\\\\ \to 30[/tex]
The value will be substituted by x=3 into its second expression:
[tex]\to 6(3+2)\\\\ \to 6(5)\\\\ \to 30[/tex]
So, it will prove that both the two expressions are equivalent.

Karl is comparing the interest rates for accounts at two different banks. He will deposit $600 into an account and will not make any additional deposits or withdrawals. Bank Q offers 1% interest compounded annually. Bank R offers 1.5% simple interest.
Answers
Answer: bank R for 1 year
Step-by-step explanation:
Given
Principal deposit is [tex]P=\$600[/tex]
Bank Q offers 1% interest compounded annually
Bank R offers 1.5% simple interest annually
For Bank Q, Compound interest is given by
[tex]\Rightarrow P[1\frac{R}{100}]^t-P[/tex]
for 1 year it is
[tex]\Rightarrow 600[1+\frac{1}{100}]-600=\$6[/tex]
For bank R, simple interest is
[tex]S.I.=\dfrac{P\times R\times T}{100}[/tex]
for 1 year it is
[tex]\Rightarrow S.I.=\dfrac{600\times 1.5\times 1}{100}=\$9[/tex]
Clearly, bank R offers more interest for 1 year

Mr Jones bought a snowboard. The 6% sales tax on the snowboard was $32.50. What was the total cost including the sales tax? (rounded to nearest cent)
Answers
Answer: $574
Step-by-step explanation:
First we need to calculate the price of the snowboard before the addition of the tax. This will be represented by x. Therefore,
6% of x = $32.50
0.06 × x = $32.50
0.06x = $32.50
x = $32.50 / 0.06
x = $541.67
Therefore, the total cost including the sales tax will be:
= $541.67 + $32.50
= $574.17
= $574
