Answer:
10,000 ft^2
Step-by-step explanation:
Let x represent length alongside Jane’s house and y represent width of garden.
We have been given that Jana has 200 feet of fencing to enclose a rectangular vegetable garden. One side of the garden will be alongside Jane’s house so only three sides will need to be fenced.
The fencing on 3 sides of garden will be equal to perimeter of garden on three sides.
p = x + 2y
200 = x + 2y
We know that area of rectangle is equal to length times width that is A = xy .
From perimeter equation, we will get:
x = 200 - 2y
Substituting this value in area equation, we will get:
A(y) = (200-y)y
Now, we need to find derivative of area of function.
A(y) = 200y - y^2
A'(y) = 200 - 2y
Now, we will set derivative equal to 0 to find critical points.
200 - 2y = 0
200 = 2y
y = 100
So thus the area will be maximum when 100.
A(y) = 200y - y^2
Substituting y for 100 we get A(100) = 10,000

O A. y-2x+12
O B. y--{x+12
O C. y=
O D. y=-3x+12
Answer:
B. y = -2/3x + 12
Step-by-step explanation:
Formula to find the slope when given two points on a line:
y2 - y1
x2 - x1
Substitute the two given points (6, 8) (9, 6):
6 - 8
9 - 6
Slope = -2/3x
We found the slope! And the answer choices already gave us one y-intercept, which is 12. The last thing we do is we form an equation with the information we solved and that was given to us.
y = slope (x) + y-intercept
y = -2/3x + 12
The answer choice that matches this equation is B.
In conclusion, the equation that best estimates the line of best fit shown above is answer choice B.
An equation of a line with given coordinates is y= -2/3 x+12. Therefore, option B is the correct answer.
What is the equation of a line?The general equation of a straight line is y=mx+c, where m is the gradient, and y = c is the value where the line cuts the y-axis. This number c is called the intercept on the y-axis.
From the given graph, the coordinate points are (6, 8) and (9, 6).
We know that, the formula to find the slope of a line is slope = (y₂-y₁)/(x₂-x₁).
Here, slope = (6-8)/(9-6)
= -2/3
Substitute m=-2/3 and (x, y)=(6, 8) in y=mx+c, we get
8=-2/3 (6)+c
8=-4+c
c=12
So, equation of a line is y= -2/3 x+12
Therefore, option B is the correct answer.

. find the height of triangle ADC if the base is AC.
9514 1404 393
Answer:
4 cm
Step-by-step explanation:
The area of the triangle is half the area of the rectangle. The base of the triangle is the diameter of the circle, 14 cm. So the height is found from ...
A = 1/2bh
(56 cm²)/2 = 1/2(14 cm)h
h = (28 cm²)/(7 cm) = 4 cm
The height of triangle ADC is 4 cm.

A square piece of cardboard of sides 15 cm is folded to make a cube of sides 5 cm.
Is there enough cardboard?
Answer:
Step-by-step explanation:
The 15 cm by 15 cm piece of cardboard area = 225 cm².
A cube has six congruent faces. If each edge is 5 cm, the surface area is 6×5² = 150 cm². So there is enough cardboard to make a cube, but not by folding. You'd have to do some cutting and taping.

A function does not have any x-intercepts. What

The domain exists on all real numbers i.e {x∈R}∈
The range exists all on real numbers except at y = 0
Domains are all input values of a function for which the function exists while ranges are all the output values for which the function exists.
Since the x-intercept of a function exists at where y = 0, this means that the point where a function does not have any x-intercepts are all other points on the graph except at y = 0.

The sum of first 'n' terms. Sn of a particular Arithmetic Progression is given by Sn=12n - 2n^2. Find the first term and the common difference
Let a be the first term and d the common difference between consecutive terms. Then the next few terms in the sequence are
a + d
a + 2d
a + 3d
and so on, up to the k-th term
a + (k - 1) d
The sum of the first n terms of this sequence is
[tex]\displaystyle S_n = \sum_{k=1}^n(a+(k-1)d) = 12n-2n^2[/tex]
Expanding the sum, we have
[tex]\displaystyle S_n = \sum_{k=1}^n (a+(k-1)d) \\\\ S_n = \sum_{k=1}^n(a-d+dk) \\\\ S_n = (a-d)\sum_{k=1}^n1+d\sum_{k=1}^nk \\\\ S_n = (a-d)n+\frac{d}2n(n+1) \\\\ S_n = (a-d)n+\frac{d}2(n^2+n) \\\\ S_n = \left(a-\frac{d}2\right)n+\frac{d}2n^2[/tex]
It follows that
a - d/2 = 12
d/2 = -2
Solve these equations for a and d.
d/2 = -2 ==> d = -4
a - d/2 = a + 2 = 12 ==> a = 10
So the sequence is
10, 6, 2, -2, -6, -10, -14, …

Answer:
x = 1/2 or 0.5
Step-by-step explanation:
8(-2x + 1) = 0
Distribute the 8 by multiplying 8 by what's inside of the parenthesis (-2x and 1)
8 * -2x = -16x
8 * 1 = 8
We now have
-16x + 8 = 0
Subtract 8 from both sides
-16x + 8 - 8 = 0 - 8
-16x = -8
Divide both sides by -16
-16x/-16 = -8/-16
x = 1/2
8( -2x + 1 ) = 0
S O L U T I O N :8( -2x + 1 ) = 0Simplify the left hand side
-16x + 8 = 0Transposing -16x to the other side
8 = 16xCross multiplying we get
x = 8/16x = ½x = 0.5Hence the value of x is 0.5 or ½

Value of line XZ = 6a + 24
Find:
Value of "a" and line YZ
Computation:
We know that

12a = 6a + 24
6a = 24
a = 4
Value of a = 4
So,
Value of line YZ = 5a
