In 1999. Sara and her brother Xzavier got money when their rich uncle died. They
each got the same amount of money. Sara bought some land in the country
because she heard they would be building houses near there some day. She
bought 300 acres of land with all of the money she got from her uncle,
$600,000, in 2000. In 2003 they extended the main highway to go near her land
and she sold 100 acres for $2700 lacre. In 2005 she sold half of the land she had
left for $3600 lacre. In 2007 they started a long-term project to build houses in
the area and built a Lowes, a Food Lion, A Bank of America and a Burger King on
the main street. Finally, in 2010. Sara sold the rest of her land for $400,000. What
was her total profit when she finished selling all of the land?

Step-by-step explanation:
When you simplify 2x-2>12, it's like an algebra problem where you just add 2 to both sides and then divide by 2. Same for 2x+3>7, except you subtract 3 and then divide by 2

Answer:
Step-by-step explanation:
A tiny hint. When you are looking for the opposite side of a triangle and the function you use is the tangent, the side opposite is always going to be larger than the side adjacent. That happens when theta is greater than 1 when the angle is larger than 45.
Phew! I didn't know the hint was going to be that long.
The trig function that does not involve the hypotenuse is the Tangent or Tan(x).
C
Tan(x) = opposite / Adjacent.
The opposite side is the side not connected to the reference angle (x)
The adjacent side makes up the angle and is not the hypotenuse.
Tan(46) = 1.036
Side adjacent = 8
So the answer is either A or C. I'm guessing it's C.
Tan(46) = x/8
1.036 = x / 8 Multiply by 8
8*1.036 = x
x = 8.28

Is (3, –2) a solution for the following system? Yes or No x + y = 1 2x + 3y = 1
Answers
Answer:
NO
Step-by-step explanation:
Plugging in 3 for X and -2 for Y
X + Y = 12X _ 3Y = 1
3 + -2 = 12*3 + 3 * -2 = 1
1 = 36 + 3 * -2 = 1
1 = 36 + -6 = 1
1 = 30 = 1
So NO, (3, -2) is not a solution.
Find the missing side of each right triangle (Pythagorean’s #Theorem)
Answers
Answer:
3
Step-by-step explanation:
The formula for the Pythagorean's Theorem is a^2 + b^2 = c^2, so first you know that hypotenuse is the longest side or the opposite side from which the right angle is which in this case is the 6 so you are looking for a leg rather then the hypotenuse which means we are going to be doing subtraction.
a^2 + b^2 = c^2
√27^2 - b^2 = 6^2
27 - b^2 = 36
-27 -27
b^2 = 9
b^2 = √9
b = 3Rewrite the quadratic function below in Standard Form.
y = (x - 4) (x + 3)
Answers
the standard form of a quadratic formula is
y = ax^2 + bx + c
in this case you will solve using foil method
(× - 4)(x + 3)
(x × x) +( x × 3 )(- 4 × x) ( -4)× 3))
x^2 + 3x - 4x -12
x^2 - x - 12
therefore
y = x^2- x - 12

O fx) - cos(x) + 3
O fx) - 3 sin(x)
O fx) - 3 cos(x)
Answers
Answer:
D^^^
Step-by-step explanation:
The graph of the function is f ( x ) = 3cos ( x )
What is Equation of Graph of Polynomials?Graphs behave differently at various x-intercepts. Sometimes the graph will cross over the x-axis at an intercept. Other times the graph will touch the x-axis and bounce off.
Identify the even and odd multiplicities of the polynomial functions' zeros.
Using end behavior, turning points, intercepts, and the Intermediate Value Theorem, plot the graph of a polynomial function.
The graphs cross or are tangent to the x-axis at these x-values for zeros with even multiplicities. The graphs cross or intersect the x-axis at these x-values for zeros with odd multiplicities
Given data ,
Let the equation be represented as A
Now , the value of A is
f ( x ) = 3cos ( x ) be equation (1)
On simplifying , we get
The function passes through the point P ( 0 , 3 )
So , when x = 0
f ( 0 ) = 3 cos ( 0 )
f ( 0 ) = 3
And , the value of y = 3
The amplitude of the function is y-max = 3
Hence , the function is f ( x ) = 3cos ( x ) and the graph is plotted

m<CAD= 23 degrees
m<CAB= 67 degrees
Step-by-step explanation:
From the diagram shown;
arc ADC + arc CAB = 360
226 + arcCAB = 360
arc CAB = 360 - 226
arc CAB = 134
Also arcCD = 226 - 180
arcCD = 46degrees
Since <A = 1/2arcCD
m<CAD = 1/2* 46
m<CAD= 23 degrees
m<CAB = 90 - <A
m<CAB = 90 - 23
m<CAB = 67degrees

Answer:
9 puppies can be fed.Step-by-step explanation:
Given that:
A dog is fed 312 cups of food. A puppy is fed 35 of that.To Find:
How much is the puppy fed?Let us assume:
x puppies can be fed.Finding the number of puppy:
Puppy : Food = Puppy : Food
⟶ 35 : 1 = 312 : x
⟶ 35/1 = 312/x
Cross multiplication.
⟶ 35x = 312
⟶ x = 312/35

What are coordinates?Coordinates are a pair of integers (Cartesian coordinates), or occasionally a letter and a number, that identify a certain place on a grid, often referred to as a coordinate plane.
Given that scatter plot lies in quadrant 1 of a coordinate plane, and the 14 points are plotted in the first quadrant.
We need to find the range of x and y values for this scatter plot.
The x values of the 14 points are given as;
2, 4, 4,1, 5, 5, 5, 5, 6, 6, 7, 8, 9.5, 9.5
The y values of the 14 points are given as;
5, 6, 9, 7.2, 6, 6.8, 8, 9, 7, 8.5, 10, 10.5, 9.5, 11.4
We can conclude that that most of the points are clustered between x-values 4 and 6 and y-values 6 and 9.
Therefore, the points are clustered between the x-values 4 and 6 and y-values 6 and 9.
