*URGENT NEED TO PASS FOR GRADUATION*
built for the 1976 olympic games in montreal canada, the tower is 156 meters tall, measured vertically from the ground to the top. the tower makes a 45 degree angle with the ground. if you were to climb to the top and then accidentally drop your keys, where would you start looking for them?
Answer:
156 meters from the bottom of the tower--------------------------------
The height of the tower is the leg of the isosceles right triangle, since one of angles is 45 degrees.
The horizontal distance from the to the point where you dropped your keys is same as the vertical distance, 156 meters, because it is the other leg of the triangle.
What is an example of a linear line?
An equation that depicts a straight line on a graph is said to be linear line.
What is linear line?
Linear refers to a straight line. Straight-line graphs called linear graphs are used to show the relationship between two values. The single straight lines on this graph assist to represent a result. The phrase "linear" refers to a straight line and excludes the usage of curves, dots, bars, etc.
A linear line can include more than one variable. Linear lines with two variables, for example, are those that have two variables in them.

Answer:
[tex]m=\frac{1}{2}[/tex]
Step-by-step explanation:
The average rate of change (m) for the given line segment can be found with
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Given the graph, the following values can be recorded:
[tex](x_1,y_1)=(-1,-5)\\(x_2,y_2)=(1,-4)[/tex]
So,
[tex]m=\frac{(-4)-(-5)}{(1)-(-1)}\\m=\frac{-4+5}{1+1}\\m=\frac{1}{2}[/tex]
This answer makes sense in both sign and scale with the given image.
how do you solve this ?
Step-by-step explanation:
first of all, remember for life :
the sum of all angles in a triangle is always 180°.
so, in this right-angled triangle we have therefore
180 = b + 90 + 71
b = 180 - 90 - 71 = 19°
and then regarding a and b :
the sum of all angles around a single point on one side of a line is also always 180°.
why ? because the line can be seen as the extended diameter of a circle, with that point being the center of the circle. and one side of the line is representing half of that circle. and a half-circle is 180°.
so,
a + b = 180
a + 19 = 180
a = 180 - 19 = 161°
FYI, the reason for the first principle (all angles in a triangle are together 180°) is also based on a half-circle concept : any right-angled triangle can be seen as inscribed into a half-circle, with the Hypotenuse (the baseline opposite of the 90° angle) being the diameter of the circle, and the center of the circle being the midpoint of the Hypotenuse.

Judy and Cassie each opened a savings account on the same day. Judy started by putting $300 in her account, and she will deposit an additional $12 each week. Cassie made an initial deposit of $100, and she will add $20 more each week. Eventually, Judy and Cassie will each have the same amount saved. How many weeks will that take?
Write a system of equations, graph them, and type the solution.
Answer: 25 weeks
Step-by-step explanation:
Let W represent the number of weeks
Judy equation is
12W + 300
Cassie equation is
20W + 100
Now let's solve it! Our system of equation is
12W + 300 = 20W + 100
Subtract 300 from both sides
12W = 20W -200
Subtract 20W from both sides
-8W = -200
W = 25 weeks
So, it takes 25 weeks for Judy and Cassie to have the same amount saved.
Answer:
let judy = 300 + 12W
cassie = 100 + 20W
300 + 12W = 100 + 20W
300 - 100 = 20W - 12W
200 = 8W
W = 25
CHECKING:
300 + 12(25) = 100 + 20(25)
300 + 300 = 100 + 500
600 = 600
Therefore, it will take 25 days for Judy and Cassie so that they have the same amount saved.

Answer:
(x=2, y=3) and (x=12, y=1/2)
Step-by-step explanation:
14 - 4[tex]\sqrt{6}[/tex] = ([tex]\sqrt{x}[/tex] - 2[tex]\sqrt{y}[/tex])^2
14 - 4[tex]\sqrt{6}[/tex] = ([tex]\sqrt{x}[/tex] - 2[tex]\sqrt{y}[/tex])([tex]\sqrt{x}[/tex] - 2[tex]\sqrt{y}[/tex])
14 - 4[tex]\sqrt{6}[/tex] = [tex]\sqrt{x}[/tex]([tex]\sqrt{x}[/tex] - 2[tex]\sqrt{y}[/tex]) - 2[tex]\sqrt{y}[/tex]([tex]\sqrt{x}[/tex] - 2[tex]\sqrt{y}[/tex]) ==> distribute ([tex]\sqrt{x}[/tex] - 2[tex]\sqrt{y}[/tex]) to [tex]\sqrt{x}[/tex] and
2[tex]\sqrt{y}[/tex]
14 - 4[tex]\sqrt{6}[/tex] = ([tex]\sqrt{x}[/tex] * [tex]\sqrt{x}[/tex]) - ([tex]\sqrt{x}[/tex] * 2[tex]\sqrt{y}[/tex]) - (2[tex]\sqrt{y}[/tex] * [tex]\sqrt{x}[/tex]) - (2[tex]\sqrt{y}[/tex] * (-2[tex]\sqrt{y}[/tex])) ==> use
distribution property
14 - 4[tex]\sqrt{6}[/tex] = (x) - (2[tex]\sqrt{xy}[/tex]) - (2[tex]\sqrt{xy}[/tex]) - (-4[tex]\sqrt{y}[/tex] *[tex]\sqrt{y}[/tex]) ==> simplify
14 - 4[tex]\sqrt{6}[/tex] = (x) - (4[tex]\sqrt{xy}[/tex]) - (-4y)
14 - 4[tex]\sqrt{6}[/tex] = (x) - (4[tex]\sqrt{xy}[/tex]) + 4y ==> subtracting by a negative number is
equivalent to adding by a positive number
14 - 4[tex]\sqrt{6}[/tex] = x + 4y - 4[tex]\sqrt{xy}[/tex] ==> notice any similarities?
x + 4y = 14
[tex]\sqrt{xy}[/tex] = [tex]\sqrt{6}[/tex]
xy=6 ==> solve for x
x = 6/y ==> isolate x by dividing by y on both sides
6/y + 4y = 14 ==> plugin 6/y for x in x + 4y = 14
(6/y + 4y = 14) * y ==> multiply the equation by y to remove fractions
6 + 4y^2 = 14y
4y^2 - 14y + 6 = 14y-14y
4y^2 - 14y + 6 = 0
2y^2 - 7y + 3 = 0 ==> divide both sides by 2 to simplify the equation
2y^2 - 1y - 6y + 3 = 0 ==> -1y - 6y = -7y
y(2y - 1) - 3(2y - 1) = 0 ==> factor the equation
(y - 3)(2y - 1) = 0
y - 3 = 0 ==> y=3
2y - 1 = 0 ==> 2y = 1 ==> y = 1/2
y=3: 3x = 6 ==> plugin 3 for y in xy = 6
x = 2 ==> divide both sides by 3
y=1/2: x/2 = 6 ==> plugin 1/2 for y in xy = 6
x = 12 ==> multiply both sides by 2
When y=3, x=2. When y=1/2, x=12
Hence, the answers are (2, 3) and (12, 1/2).
The expression will be simplified as x + 4y + 4√x√y -14 + 4√6 = 0.

The drama club is selling tickets to their play to raise money for the show's expenses. Each student ticket sells for $4, and each adult ticket sells for $8. There was a total of $640 in revenue from the sale of 100 total tickets. Graphically solve a system of equations in order to determine the number of student tickets sold, x, and the number of adult tickets sold, y.
The number of student tickets sold is 40 and the number of adult tickets sold is 60.
Define System of equations
A set of simultaneous equations, also known as a system of equations or an equation system, is a finite set of equations for which common solutions are sought.
Given,
Each student ticket sells for = $4
Each adult ticket sells for = $8
Total tickets sale = 100
Revenue from the sale of 100 tickets = $640
Let, x = number of student tickets sold
and, y = number of adult tickets sold
so, let's form a equation
x + y = 100 ------(i)
4x + 8y = 640 -------(ii)
Rewrite eq(i),
x = 100 - y
Now, substitute x value in eq(ii)
4(100- y) + 8y = 640
400 - 4y + 8y = 640
4y = 640 - 400
y = 240 / 4
y = 60
Now, put y value in eq(i)
x + 60 = 100
x = 40
Hence, the number of student tickets sold is 40 and the number of adult tickets sold is 60.
Now, to solve graphically
Let's rewrite the eq(i) and eq(ii)
y = 100 - x
y = 80 - (1/2) x

What is the slope intercept form of the inequality 2x 3y 12?
The level of a line's slope indicates its steepness, y = (2/3)x - 4 is the slope intercept form of the inequality 2x - 3y = 12.
How do one find the slope of a graph?The slope is computed mathematically as "rise over run" (change in y divided by change in x).
In accordance with the slope equation, the slope of such a line may be determined by dividing the rise of the line between two positions by the run of the same line between the same two sites.
The above equation is a standard straight-line equation, and we are asked to change it to slope-intercept form, which is given as y = mx + c. "m" denotes the slope of the line and "c" denotes its intercept.
Now, it is given that,
2x - 3y = 12
or, - 3y = 12 - 2x
or, 3y = 2x - 12
or y = (2/3)x - 4

What is the slope intercept form of the inequality 2x - 3y = 12.
18 The three solids A, B and C are similar such that
and
the surface area of A: the surface area of B=4:9
the volume of B: the volume of C = 125:343
Work out the ratio
the height of A: the height of C
Give your ratio in its simplest form.
Answer:
1:1
Step-by-step explanation:
Since the surface area of A is 4 times the surface area of B, and the volume of B is 125 times the volume of C, we can write the following proportion:
(surface area of A) / (surface area of B) = (volume of B) / (volume of C)
(height of A)^2 / (height of B)^2 = (height of B)^3 / (height of C)^3
We can then cross-multiply and simplify to find the ratio of the heights:
(height of A)^2 / (height of C)^2 = (height of B)^3 / (height of B)^3
(height of A)^2 = (height of C)^2
Therefore, the ratio of the height of A to the height of C is 1:1, or simply 1.
Solve and graph by using systems of inequalities.
A 24 hour radio station plays only classical music, jazz music, talk programs, and news. It plays at most 12 hours of music per day, of which at least 4 hours is classical. Jazz music gets 25% as much time as classical. Write and graph a system of inequalities.
PLEASE HELP!!!
The inequality that represents the most no. of music played is,
C ≤ 4, J ≤ 1 and 4C + 0.25C ≤ 12
What is inequality?When two expressions are connected by a sign like "not equal to," "greater than," or "less than," it is said to be inequitable. The inequality shows the greater than and less than relation between variables and the numbers.
Inequality is a relation that compares two numbers or other mathematical expressions in an unequal way.
The symbol a < b indicates that a is smaller than b.
When a > b is used, it indicates that a is bigger than b.
a is less than or equal to b when a notation like a ≤ b.
a is bigger or equal value of an is indicated by the notation a ≥ b.
Given, the radio station plays at most 12 hours of music per day. Let C denotes classical music, J denotes jazz music, and 25% of 4 hours be 1 hour.
The inequality representing this situation is
C ≤ 4 and J ≤ 1.
4C + 0.25C ≤ 12. (less than or equal to is at most)
4.25C ≤ 12.

What are the roots of the quadratic equation x² 5x 6 0?
The two solutions to the equation x² + 5x + 6 = 0 are x = -2 and x = 3. This means that when we substitute either of these values into the equation, the left-hand side of the equation will be equal to 0.
To find the roots of a quadratic equation, we need to set the equation equal to 0 and then solve for x. In this case, we have the equation x² + 5x + 6 = 0. we can use the quadratic formula. The quadratic formula states that the two solutions for x are given by x = (-b ± √(b² - 4ac))/2a. For our equation, this gives us x = (-5 ± √(5² - 4(1)(6)))/2(1). Once we simplify this, we get x = (-5 ± √(-19))/2. Since the square root of a negative number is not real, we can discard this solution. This leaves us with x = -2 and x = 3. This means that when we substitute either of these values into the equation, the left-hand side of the equation will be equal to 0.
x = (-5 ± √(5² - 4(1)(6)))/2(1)
= (-5 ± √(-19))/2
= (-5 ± i√19)/2
