What is a linear equation in math?
A linear equation only has one or two variables. No variable in a linear equation is raised to a power greater than 1 or used as the denominator of a fraction. When you find pairs of values that make a linear equation true and plot those pairs on a coordinate grid, all of the points lie on the same line.Given,
men = 1265
women = 1150
Total women and men -
men + women = 2415
= 5450-2415 ⇒ 3435
Therefore, 3435 were children visited the India gate.

9. Find the values of x and y.
Write answers in simplest radical form.
x=______ y=_____
Answer:
x = 3√3
y = 6
Step-by-step explanation:
The geometric mean relations between segments intersecting the long hypotenuse and its parts can be used to find the values of interest.
Altitudex = √(9·3) = 3√3
Short sidey = √((9+3)·3) = 6
__
Additional comment
These right triangles are all similar, so corresponding sides are proportional. When the proportions are solved for a missing side, a geometric mean relation results. (The geometric mean of 'a' and 'b' is √(ab).)
Identify the segments above the horizontal line as w, x, y. (x and y are already identified in this figure.)
The ratio of short side to long side is ...
x/9 = 3/x ⇒ x² = 9·3 ⇒ x = √(9·3)
The ratio of short side to hypotenuse is ...
y/(9+3) = 3/y ⇒ y² = (9+3)·3 ⇒ y = √((9+3)·3)
Likewise, the ratio of long side to hypotenuse is ...
w/(9+3) = 9/w ⇒ w² = (9+3)·9 w = √((9+3)·9) = 6√3

Find the value of z.
Applying the angle of intersecting chords theorem, the value of z is: D. 100.
What is the Angle of Intersecting Chords Theorem?According to the angle of intersecting chords theorem, in a circle like the one shown in the image above, where two chords intersect to form vertical angles, the theorem states that the angle formed equals half of the sum of the measures of the arcs intercepted by the angles.
Applying the angle of intersecting chords theorem, let's find x first:
73 = 1/2(96 + x)
Multiply both sides by 2
2 × (73) = 1/2(96 + x) × 2
146 = 96 + x
Subtract both sides by 96
146 - 96 = 96 + x - 96
50 = x
x = 50°
Therefore:
x + z + 96 + 114 = 360° [full circle measure]
Plug in the value of x
50 + z + 96 + 114 = 360
z + 260 = 360
Subtract both sides by 260
z + 260 - 260 = 360 - 260
z = 100°
The answer is: D. 100°.

Trigonometrical ratiosFrom the question, we are to determine which of the given trigonometrical ratios for the given triangle are correct
The given triangle is a right angle triangle
Using SOH CAH TOA
sin C = 9/15
∴ The option sin C = 9/15 is correct
Also,
Using SOH CAH CAH

Dario is the kicker for his high school football team. The path of the football when kicked can be
represented by the quadratic function y = -16x²
-16x2 +85x, where x is the horizontal distance (in
feet) and y is the height (in feet). How far does Dario kick the football? Express your answer as a
decimal rounded to the nearest hundredth.
Answer:
Assunming that the equation is y = -16x² +85x, I suggest Dario find a new profession. He kicks the ball 133 feet high, but it only travels 2.7 feet downfield at that point. It will have travelled 2*2.7 feet or 5.4 feet horizontal when it returns to ground.
Step-by-step explanation:
We can answer the question of how hiogh and far the ball travels (in feet) by either of two methods. The first is to differentiate the equation and set it equal to 0, and the second is the graph it and look for the vertex and x intercept.
Differentiate
y = -16x² +85x
The first derivative produces an equation that gives us the slope of the line at any point x. At the ball's top height, it stops and reverses direction, a point at which the slope is zero.
y = -16x² +85x
d(y)/d(x) = -32x + 85
0 = -32x + 85
32x = 85
x = 2.66 feet horizontal distance when the ball reaches its peak.
At x = 2.66, y is 112.9 feet high
When the ball returns, it adds amnother 2.66 feet to the horizontal distance, for a total of 5.4 feet.
Graph:
See attached plot of the function.
Horizontal distance is 2.66 feet and height is 133 feet. The x-intercept is at 5.4 feet.
After all that, the ball only travelled downfield (we hope downfield) a total of 5.4 feet.

How tall is the flagpole?See attachment for the diagram, when redrawn
Start by calculating the length AB using the following tangent function
tan(22) = BC/AB
This gives
tan(22) = 9/AB
Make AB the subject
AB = 9/tan(22)
Evaluate the quotient
AB = 22.3
The length DB is then calculated using:
tan(9) = DB/AB
This gives
tan(9) = DB/22.3
Make DB the subject
DB = 22.3 * tan(9)
Evaluate
DB = 3.35
The height of the flagpole is then calculated as:
Height = DB + BC
This gives
Height = 3.35 + 9
Evaluate
Height = 12.35
Approximate
Height = 12.4
Hence, the height of the flagpole is 12.4 meters
How to determine the altitude of the balloon?The diagram that illustrates the scenario is added as an attachment

tan(57) = x/y and tan(72) = (15 + x)/y
Make y the subject in tan(57) = x/y and tan(72) = (15 + x)/y
y = x/tan(57) and y = (15 + x)/tan(72)
Substitute y = x/tan(57) in y = (15 + x)/tan(72)
x/tan(57) = (15 + x)/tan(72)
Evaluate the tangent ratios
x/1.5 = (15 + x)/3.1
Cross multiply
3.1x = 22.5 + 1.5x
Evaluate the like terms
1.6x = 22.5
Divide by 1.6
x = 14.1
