ALGEBRA 1 QUESTION
Ingrid hit a golf ball. The height of the ball (in meters above the ground) t seconds after being hit is modeled by
h(t)=-5t^2+30t
1) Rewrite the function in a different form (factored or vertex) where the answer appears as a number in the equation.
2) How many seconds after being hit does the ball reach its highest point?
__________seconds
Answer:
[tex]\huge\boxed{\text{1. } h(t) = -5(t-3)^2 + 45}[/tex]
[tex]\huge\boxed{\text{2. 3 seconds}}[/tex]
Step-by-step explanation:
If we're looking for the point at with the ball reaches its highest point, we want to find the graph's vertex. In order to get the equation into a form with the vertex in it, we need to convert the equation into vertex form. This is an equation in the form [tex]y=a(x-h)^2 + k[/tex], h being the x value of the vertex, and k being the y value of the vertex.
In order to convert our equation, [tex]-5t^2+30t[/tex] into vertex form, we can algebraically manipulate it to get it into the form we want.
[tex]-5t^2 +30t[/tex] [tex]-5 \cdot t^2 + 30t[/tex] (Separate the -5 from the t^2)[tex]-5(t^2-6t+0)[/tex] (Factor out a -5)[tex]-5(t^2 -6t + (-3)^2 - (-3)^2 + 0)[/tex] (Completing the Square)[tex]-5((t-3)^2 - (-3)^2 + 0)[/tex] (Binomial Formula)[tex]-5((t-3)^2 - 9)[/tex] (Simplify)[tex]-5(t-3)^2 + 45[/tex] (Factor the -5 back in)Therefore, our equation with the vertex in it is [tex]-5(t-3)^2 + 45[/tex]. To find the vertex, we can examine the equation to find the values of h and k in the formula [tex]y=a(x-h)^2 + k[/tex] (where the vertex coordinates are (h, k)).
It seems that h is 3 and k is 45. Therefore, the coordinate of the vertex is (3, 45). Since it asks for how many seconds after being hit does the ball reach its highest point, we would take the x value since x represents seconds. This is 3. Therefore, the ball reaches its highest point after 3 seconds.
Hope this helped!
What is the area trapezoid ABCD A(-1,5) B(3,2) C(0,-2) D(-13,-11)
Answer:
62.5
Step-by-step explanation:
slope of AB = (5-2)/(-1 - 3) = -3/4
slope of BC = (2 - -2)/(3-0) = 4/3
AB ⊥ BC (slope -3/4 vs 4/3)
seg AB = √(-1 - 3)² + (5 - 2)² = √25 = 5
seg BC = √(3 - 0)² + (2 - -2)² = √25 = 5
seg AD = √(-1 - -13)² + (5 - -11)² = √400 = 20
Area (BC + AD) * AB / 2 = (5 + 20) * 5 / 2 = 62.5

What are the x-intercepts of f(x) = x(x + 1)(x - 4)(x+8)??
Answer:
f(x)= 3x^2+5x
Step-by-step explanation:
f(x)= x(x+1)(x-4)(x+8)
f(x) = x^2 + x + x^2 - 4x + x^2 + 8x
f(x) 3x^2 + 5x

What is the solution to the equation below? Round your answer to two
decimal places.
5* = 55
O A. x = 2.40
B. X= 2.49
C. x = 1.04
D. x= 0.40
Given:
The equation is
[tex]5^x=55[/tex]
To find:
The value of x.
Solution:
We have,
[tex]5^x=55[/tex]
Taking log both sides, we get
[tex]\log (5^x)=\log (55)[/tex]
[tex]x\log (5)=\log (55)[/tex] [tex][\because \log x^n=n\log x][/tex]
[tex]x=\dfrac{\log (55)}{\log (5)}[/tex]
Using the log values, we get
[tex]x=\dfrac{1.740}{0.699}[/tex]
[tex]x=2.48927[/tex]
[tex]x\approx 2.49[/tex]
Therefore, the correct option is B.

In a basketball game Jamarcus made 15 out of 25 shots and tyrell made 32 out of 50 shots who’s the better shooter
Answer:
Jamarcus is the better shooter
Step-by-step explanation:
Jamarcus is better because he needs 10 more shots to reach 25 while tyrell needs 18 More shots to make 50
Answer:
Tyrell
Step-by-step explanation
Well this is simple you take Jamarcus shots made and divide it into the total shots which is 15/25=0.6 or 60%. So Jamarcus made 60% of the shots attempted. Tyrell made 32 out of 50 shots so that will be 32/50=0.64 or 64%. Since 64%>60% Tyrell is the better shooter

Three randomly chosen California students were asked how many times they drove to Mexico last year. Their replies were 4, 5, 6. The geometric mean is:
Answer:
4.93
Step-by-step explanation:
Given 3 numbers a, b and c, the formula for calculating their geometric mean is expressed as:
GM = ∛a*b*c
Given the numbers 4, 5 and 6
geometric mean = ∛4 * 5 * 6
geometric mean = ∛20*6
geometric mean = ∛120
geometric mean = 4.93
Hence the geometric mean is 4.93
