A golf ball is hit so that it travels a horizontal distance of 440 feet and reaches a maximum height of 190 feet. Determine a quadratic equation that models the path of the golf ball, assuming it starts at the origin. (4 points) Round the coefficient of x2 to the nearest ten-thousandths place, and round the coefficient of x to the nearest thousandths place. Using your understanding of parametric equations for projectile motion, what is the angle the ball takes off? Show your steps.
(1) A quadratic equation that models the path of the golf ball, is 16.0850t² - 110.560t - 190 = 0.
(2) The angle the ball takes off is 64.4⁰.
Equation of motion of the golf ballThe equation that models the motion of the gofl ball is calculated as follows;
Vertical motionVf² = V₀² - 2gh
at maximum height, Vf = 0
V₀² = 2gh
V₀ = √2gh
V₀ = √(2 x 32.17 x 190)
V₀ = 110.56 ft/s
Equation of motionh = V₀t - ¹/₂gt²
-190 = 110.56t - ¹/₂(32.17)t²
-190 = 110.56t - 16.0850t²
16.0850t² - 110.560t - 190 = 0
Horizontal motion440 = Vxt
Vx = 440/t
The time of motion, t is determined as follows;
16.0850t² - 110.560t + 190 = 0
a = 16.0850, b = -110.560, c = 190, solve using formula method
t = 8.3 s
Vx = 440 /8.3
Vx = 53.01 ft/s
Angle of projectiontan θ = (Vy) / (Vx)
tan θ = (110.56)/(53.01)
tan θ = 2.086
θ = tan⁻¹(2.086)
θ = 64.4⁰

Hello there.
Question:What type of triangle is defined by the following set of side lengths
10, 9, 5
Answer:
Acute
Step-by-step explanation:
The triangle perimeter is the sum of the lengths of its three sides.
[tex]p=a+b+c=10+9+5=24[/tex]
The semiperimeter of the triangle is half its perimeter. The semiperimeter appears in formulas for triangles to be given a separate name. the triangle inequality, the longest side length of a triangle is less than the semi perimeter.
[tex]s=\frac{p}{2} =\frac{24}{2} =12[/tex]
using Heron's formula
Heron's formula gives the area of a triangle when the length of all three sides is known.
[tex]T=\sqrt{s(s-a)(s-b)(s-c)}[/tex]
[tex]T=\sqrt{12(12-10)(12-9)(12-5)}[/tex]

Answer:
O C. x = 3, y = -6
Step-by-step explanation:
x - 2y = 152x + 4y = -18Take Equation 1 and equate to x.
x - 2y = 15x = 2y + 15Now, substitute in Equation 2.
2x + 4y = -182(2y + 15) + 4y = -184y + 30 + 4y = -188y = -48y = -6x = 15 + 2(-6)x = 3Option CAnswer:
C) x = 3, y = -6
Step-by-step explanation:
[tex]\textsf{Equation 1}:x-2y=15[/tex]
[tex]\textsf{Equation 2}:2x+4y=-18[/tex]
Rewrite Equation 1 to make x the subject:
[tex]\implies x=15+2y[/tex]
Substitute into Equation 2 and solve for y:
[tex]\implies 2(15+2y)+4y=-18[/tex]
[tex]\implies 30+4y+4y=-18[/tex]
[tex]\implies 8y=-48[/tex]
[tex]\implies y=-6[/tex]
Substitute found value of y into Equation 1 and solve for x:
[tex]\implies x-2(-6)=15[/tex]
[tex]\implies x+12=15[/tex]

Therefore, the solution to the system of equations is:

solve for w and y
Please help!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Answer:
w = 10√2
y = 20
Step-by-step explanation:
Sum of interior angles of a triangle = 180°
Therefore, the triangle on the left (with side length 10) is a right triangle,
since 180° - 45°- 45° = 90°
As this triangle is also an isosceles triangle (since it has 2 equal angles), then it will have 2 sides of the same length.
So the legs of the right triangle are both 10 units.
Using Pythagoras' Theorem to calculate the hypotenuse of this triangle:
⇒ 10² + 10² = c²
⇒ 200 = c²
⇒ c = √200
⇒ c = 10√2
The triangle with side w and base y is also isosceles triangle with base angles of 45°.
Therefore, the sides are equal in length.
So w = hypotenuse of the left triangle = 10√2
We know that the horizontal distance between the left base vertex and the top vertex of this triangle is 10, therefore y = 10 + 10 = 20

Answer:
Graph the parabola y=x2−7x+2 .
Compare the equation with y=ax2+bx+c to find the values of a , b , and c .
Here, a=1,b=−7 and c=2 .
Use the values of the coefficients to write the equation of axis of symmetry .
The graph of a quadratic equation in the form y=ax2+bx+c has as its axis of symmetry the line x=−b2a . So, the equation of the axis of symmetry of the given parabola is x=−(−7)2(1) or x=72 .
Substitute x=72 in the equation to find the y -coordinate of the vertex.
y=(72)2−7(72)+2 =494−492+2 =49 − 98 + 84 =−414
Therefore, the coordinates of the vertex are (72,−414) .

The graph of the parent function f(x) = |x| is dashed and the graph of the transformed function g(x) = |x| + k is solid. Use the slider to change the value of k. How does changing the value of k affect the graph? Positive values of k shift the graph . Negative values of k shift the graph
Answer:
Use the slider to change the value of k.
Positive values of k shift the graph ✔ up.
Negative values of k shift the graph ✔ down
Step-by-step explanation:
Transformation involves changing the position of a function.
The true statements are:
Positive values of k shift the graph up
Negative values of k shift the graph down
The functions are given as:
The equation of g(x) implies that, f(x) is translated or shifted vertically.
The possible values of k are:
k is greater than 0 i.e. positive
k is less than 0 i.e. negative
When k is positive, then the graph of the function shifts up
If otherwise (i.e. k is negative), then the graph of function shifts down
Changing the value of k in the function g(x) = |x| + k affects the graph by shifting it vertically.
What is the function?A relationship between a group of inputs and one output is referred to as a function. In plain English, a function is an association between inputs in which each input is connected to precisely one output. A domain, codomain, or range exists for every function. Typically, f(x), where x is the input, is used to represent a function.
Horizontal translation: g(x)=f(x+c).
The graph is translated as c units to the left if c>0 and c units to the right if c<0.
Vertical translation: g(x)=f(x)+k.
The graph is translated as k units upward if k>0 and k units downward if k<0.
When k is positive, the graph of g(x) is shifted upward by k units compared to the graph of f(x). This is because, for any value of x, g(x) will be greater than f(x) by k units, due to the addition of k to the absolute value of x.
Conversely, when k is negative, the graph of g(x) is shifted downward by k units compared to the graph of f(x). This is because, for any value of x, g(x) will be less than f(x) by k units, due to the subtraction of k from the absolute value of x.
Therefore, changing the value of k in g(x) = |x| + k shifts the graph vertically, either upward or downward, depending on the sign of k.
