If someone who is 5 feet tall uses a potato gun to shoot a potato in the air at 100 feet per second, we can use the function f(x)=-16x^2+100x+5 to calculate how far the potato will be from the ground at any given second (x). Use this information to determine how long it will take the potato to hit the ground.
Answers
Answer:
Step-by-step explanation:
Given the function f(x)=-16x^2+100x+5 to calculate how far the potato will be from the ground at any given second (x), the potato hits the ground when g(x) = 0
The function becomes'
0 =-16x^2+100x+5
-16x^2+100x+5 = 0
multiply through by minus
16x^2-100x-5 = 0
x = 100 ±√100²-4(16(-5))/2(16)
x = 100±√10000+320/32
x = 100±101.59/32
x = 100+101.59/32
x = 202.59/32
x = 6.299 secs
Hence the potato will hit the ground after 6.299secs
The time taken by potato to hit the ground is [tex]6.299[/tex] seconds.
The potato will be from the ground at any given second (x) is given by below function.
[tex]f(x)=-16x^2+100x+5[/tex]
To find the time taken by potato to hit the ground is , equate given function to zero.
[tex]f(x)=-16x^2+100x+5=0\\\\-16x^2+100x+5=0\\\\x=\frac{-100\pm\sqrt{(100)^{2}+4*16*5 } }{-16*2} \\\\x=\frac{-100\pm101.587 } {-32} \\\\x=6.299,x=-0.049[/tex]
Since, time can not be negative.
So that we will consider , [tex]x=6.299 s[/tex]
Hence, the time taken by potato to hit the ground is [tex]6.299[/tex] seconds.

What is mathematical function?A function in mathematics from such a set X to either a set Y allocates exactly 1 element of Y to every element of X. The sets X and Y are collectively referred to as the function's domain and codomain, respectively. Initially, functions represented the idealized relationship between two changing quantities.
A planet's position, for instance, depends on time. In the past, the idea was developed with both the infinitesimal calculus toward the conclusion of the seventeenth century, and the functions that were taken into consideration were differentiable until the 19th century. Graphs E, B, as well as D all represent functions and relations, respectively.
Therefore, graphs E, B, as well as D all represent functions and relations, respectively.

what is the slope of a line that has a y-intercept but no x intercept
Answers
Answer:
The slope of a line that has a y-intercept but no x-intercept will be zero.
Step-by-step explanation:
If the line has no x-intercept, then it never intersects the x-axis, so it must be parallel to the x-axis.
If a line does not have an x-intercept, it means it would never intersect the x-axis.
Thus, it must be parallel to the x-axis, meaning its slope will be zero. It would be just a horizontal line.
For example, y=9 is the line equation that does not have an x-intercept and its slope is zero.
Therefore, the slope of a line that has a y-intercept but no x-intercept will be zero.
Which graph represents the function?
f(x)=2x√+1
Answers
Using translation concepts, it is found that the fourth graph(right graph of the bottom row) represents the function f(x).
What is a translation?A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.
The parent function is [tex]f(x) = \sqrt{x}[/tex], which has vertex at the origin.
The translated function in this problem is [tex]f(x) = 2\sqrt{x + 1}[/tex], which was vertically strecthed by a factor of 2 units(which does not change the vertex), and shifted left 1 unit, which means that the vertex is now at (0,-1).
Hence, the fourth graph(right graph of the bottom row) represents the function f(x).

Step-by-step explanation:
(-4, -1): If you see the x-axis and trace -4 and -1 from the y-axis, they both lead to a point that is on the graph.
(-2, 1): The graph, at -2 on the x-axis, lies at height 0.5, so 1 is wrong.
(0, 2): At 0, the graph lies on 2.
(4, 5): At 4 on the x-axis, the graph lies at height 5.
(2, 0): The graph is already at height 3.5 when at length 2.
If 76g of sodium reacts with chlorine to produce 214g of sodium chloride, how many grams of chlorine reacted?
need help
Answers
Answer:
138 g of chlorine is required to produce 214 g of sodium chloride if we have 76 g of sodium.
Step-by-step explanation:
We are given:
Grams of Sodium = 76 g
Grams of Sodium Chloride = 214 g
We need to find how many grams of chlorine required to produce 214 g of sodium chloride
The equation will be:
[tex]Na \ + \ Cl \ -> NaCl\\76\ g \ \ \ x \ g \ \ \ \ \ \ \ \ 214 g[/tex]
We can write: 76 (g) + x (g)=214 (g)
Solving and finding value of x
x =214-76
x=138 g
So, 138 g of chlorine is required to produce 214 g of sodium chloride if we have 76 g of sodium.
A bus driver drives 6 miles a day how many miles does the bus driver drive in 5 days?
Answers
Answer:
The bus driver drives 30 miles in 5 days.
Step-by-step explanation:
Hi,
You can use the rule of three to solve this problem.
For the first step, we need to analyze the information given:
[tex]6 (miles) = 1 (day)[/tex]
and we want to know how much miles the bus driver drives in 5 days:
[tex]x (miles) = 5 (day)[/tex]
Thus,
[tex]6 (miles) = 1 (day)[/tex] ... (1)
[tex]x (miles) = 5 (day)[/tex] ... (2)
Now, multiplying in a cross and we have:
[tex]x *1 = 5*6 \\ x = 30[/tex]
Lastly, replacing the value of x in (2):
[tex]30 (miles) = 5 (day)[/tex]
and this is the answer

The engines of a plane are pushing it due west at a rate of 250 mph and the wind is blowing from the southwest at a rate of 25 mph. find the direction of the plane
Answers
Answer:
84.26° in the south west direction.
Step-by-step explanation:
I've attached an image showing the triangle formed by the motion of the plane and the wind.
I've depicted the plane being pushed west and the wind moving south west.
Thus, the direction of motion of the plane will be angle θ.
Using trigonometric ratios;
25/250 = cos θ
cos θ = 0.1
θ = cos^(-1) 0.1
θ = 84.26°
Thus will be in the south west direction.
