Answer:
Step-by-step explanation:
original price is x
Then the decreased price will be ' x - x/6'
= 5x/6
5x/6= 75
x= (75×6)/5
x= 90
original price = £90
Answer:
£90
Step-by-step explanation:
Since it was decreased by 1/6, it is 5/6 of the original price.
divide 75 by 5 to get 15.
15 is 1/6 of the price.
To get the full price, (6/6) multiply 15x6 and you will get 90.

The area of sandbox in park is represented by 2X^2-5x-3 find the dimensions of the sandbox in terms of
Answer:
The dimension of the sandbox is (2x+1) by (x - 3)
Step-by-step explanation:
It seems the complete question will be:
The area of sandbox in park is represented by 2X^2-5x-3 find the dimensions of the sandbox in terms of x.
Step-by-step explanation:
From the question, the given expression is 2X^2-5x-3. This can be rewritten as
[tex]2x^{2} -5x-3[/tex]
If the area of the sandbox in park is represented by this expression, then the dimensions of the sandbox will be the product of the factors. To determine the factors, we will factorize the given quadratic expression.
Factorizing the expression [tex]2x^{2} -5x-3[/tex], we get
[tex]2x^{2} -6x+x-3[/tex]
[tex]2x(x-3)+1(x-3)[/tex]
[tex](2x+1)(x-3)[/tex]
Hence, the dimension of the sandbox is (2x+1) by (x - 3)

Answer:

Step-by-step explanation:
The circle has the same value of the side which is 3 so the length and width is 3 too. So the formal is L x W = Area. So this means 3 x 3 = 9
A manufacturer is interested in creating a new item. His research team starts with a model consisting of the functions =−3(+2)2+3 , y = - 3 and y = 0. What is the height of the shape?
Answer:
[tex]x = -2[/tex]
Step-by-step explanation:
Given
[tex]y=\frac{-3}{(x+2)^2}+3[/tex]
[tex]y = - 3[/tex]
[tex]y = 0[/tex]
The question has confusing details because the height of a shape do not relate to the given parameters.
A more complete question found on the brainly shows that the complete question asks for the asymptote of the function.
To do this, we have:
[tex]y=\frac{-3}{(x+2)^2}+3[/tex]
Take LCM
[tex]y = \frac{-3 + 3(x+2)^2}{(x+2)^2}[/tex]
Equate the denominator to 0
[tex](x + 2)^2 = 0[/tex]
Take square roots of both sides
[tex]x + 2 = 0[/tex]
Solve for x
[tex]x = -2[/tex]
Hence, the asymptote is at [tex]x = -2[/tex]

Answer:
6x^2^x^2+x^4
Step-by-step explanation:
Answer:
Yes your answer is correct
Step-by-step explanation:
First of all you multiply 3x with 2x which equals 6x power 2 because we sum the power. Then we multiply 6x power 2 with x power 4 which equals 6x power 6 because X is 1X so the answer is 6X power 6

Critique the reasoning of others. Sally states that the equation g(x) = x2 + 3x − 10 represents a quadratic function that is the product of the expressions that define the two linear functions a(x) = x + 2 and b(x) = x − 5. Is Sally correct? Explain.
Answer:
Step-by-step explanation:
No, not quite. She's close.
The middle term (often called the linear term) is + which means that the absolute value of the factors must be plus.

When solving the equation 3n2−15n=3 by completing the square, what is your first step?
Subtract 3 from each side of the equation.
Divide each side of the equation by 3.
Add 15n from each side.
Divide −15by 2 and square the result.
Answer: Subtract 3 from each side of the equation(A)
Step-by-step explanation:
3n2−15n=3
1:Subtract 3n2 from both sides.
-15n=3-3n2
2:Divide both sides by -15.
-15n/-15=3-3n2/-15
3:Dividing by −15 undoes the multiplication by −15.
n=3-3n2/-15
4:Divide 3−3n 2 by −15
n=n2-1/5

On a coordinate grid, a trapezoid has vertices at (−6, 9), (−6, 6), (3, −9), and (3, 12). Each square on the grid represents 1 square foot. Explain how to find the area of the trapezoid.
Answer:
The area of the trapezoid is 108 square feet
Step-by-step explanation:
The given vertices of the trapezoid are;
(-6, 9), (-6, 6), (3, -9, and (3, 12)
Let the letters A, B, C, and D represent the vertices of the trapezoid, we have;
A(-6, 9), B(-6, 6), C(3, -9) and D(3, 12)
The drawing of the trapezoid on the coordinate plane created with MS Excel is attached
The area of a trapezoid, [tex]A_T[/tex] = (a + b)×h/2
Where;
'a', and 'b' = The length of the bases (parallel sides)
h = The height of the trapezoid (The distance between the bases)
Let 'a' represent the length of the long base CD and let 'b' represent the length of the short base AB
a = √((-9 - 12)² + (3 - 3)²) = 21
∴ a = 21 feet
Similarly, we have;
b = √((9 - 6)² + (-6 - (-6))² = 3
The height, h = The distance between AB and CD = AE
We note that sides AB and CD are parallel to the y-axis, therefore, the height which is the perpendicular distance to the between AB and CD will be parallel to the x-axis
Therefore, the t-coordinates of the points A and E are both equal to 9 and the length of AE = √((3 - (-6))² + (9 - 9)²) = 9
The height of the trapezoid, AE = 9 feet
∴ The area of the trapezoid, A = (21 + 3) × 9/2 = 108
The area of the trapezoid, [tex]A_T[/tex] = 108 ft.²

Answer:
600ft²
Step-by-step explanation:
Oh boy, this is gonna be a long one, so proceed with caution:
So we're gonna start with the one to the very left, we can split this into three different rectangles:
So we got the length of the bottom minus the length we don't want there because we're doing the big rectangle:
35 - 10 = 25
25 x 20 = 500
So we're just gonna keep that on a back burner, cause now we gotta do the two smaller ones:
So we got the measure from the one side, but we gotta subtract the 10 from the other side:
20 - 10 = 10
10 x 10 = 100
Now we gotta add that all up:
500 + 100 = 600
So the area of the first shape is 600ft²

"ATTICUS_SWEETLOVER"If using the method of completing the square to solve the quadratic equation x^2+11x+30=0x 2 +11x+30=0, which number would have to be added to "complete the square"?
Answer:
(11/2)² or 121/4 would be added to the equation x ² +11x+30=0, to "complete the square".
Step-by-step explanation:
x 2 +11x+30=0
Write the equation in the form of the square
(x)^2 + 2(x) (11/2) + (11/2)^2 + 30 - 121/4= 0
Square of the first element + 2 into first element into 2nd element + square of 2nd element gives the complete square formula.
How we obtained the second element?
The mid term broken must always be equal to the mid term given.
Hence
2(x) can only be equal to 11x if we multiply it by 11 and divide it with 2.
So the second term must be 11/2 .
To complete the square this second term ( 11/2)² is added and then subtracted to keep the equation equal to the original equation.
(x)^2 + 2(x) (11/2) + (11/2)^2 + 30 - 121/4= 0
Putting it in the form of square
(x+ 11/2)^2 + 120-121/4= 0
Taking LCM and solving
(x+ 11/2)^2 - 1/4= 0
(x+ 11/2)^2 = 1/4
Taking square root on both sides
(x+ 11/2) = ± 1/2
x= - 11/2 ± 1/2
x= -10/2= -5
x= -12/2= -6
A helicopter flies from the airport on a course with a bearing of 21 degrees. After flying for 99 miles, the helicopter flies due east for some time. The helicopter flies back to the airport with a bearing of 227 degrees. How far did the helicopter fly on the final leg of its journey?
Answer:
Step-by-step explanation:
From the question we are told that:
Initial bearing [tex]\angle _1=21 \textdegree[/tex]
Initial distance [tex]d_1=99miles[/tex]
Final bearing [tex]\angle _2=227 \textdegree[/tex]
Let [tex]\triangle OAB[/tex] be the perimeter travailed
[tex]\angle OAB=90+21=111 \textdegree\\\angle ABO=270-227=43 \textdegree[/tex]
Generally the equation for OB using sine rule is mathematically given by
[tex]OB=99*\frac{sin111}{sin43}[/tex]
[tex]OB=135.52miles[/tex]
Therefore the helicopter flight on the final leg of its journey is
[tex]OB=135.52miles[/tex]
