Answer:
f(n) = 0.2n + 4.8
4.8
Step-by-step explanation:
Given the explicit formula :
an = 5 +0.2(n - 1)
Expressing an in function form f(n):
f(n) = 5 + 0.2(n - 1)
f(n) = 5 + 0.2n - 0.2
f(n) = 5 - 0.2 + 0.2n
f(n) = 0.2n + 4.8
The y - intercept :
Set n = 0
f(n) = 0.2n + 4.8
f(0) = 0.2(0) + 4.8
= 0 + 4.8
= 4.8
y intercept = 4.8
Suppose that a bike rents for 50php plus 8php per hour. Write an equation in slope-intercept form that models this situation.
Answer: C(x) = (8 php)*x + 50 php.
Step-by-step explanation:
In a linear equation:
y = a*x + b
a is the slope.
x is the variable
b is the y-intercept.
In this case, we have
The rent is 50 php fixed, plus 8 php per hour.
Then we will pay the 50php only one time, and it does not depend on the number of hours that we rent, then this is the y-intercept.
then if we rent the bike for x hours, we will pay a plus of x*8 php.
Then the total cost for x hours, C(x), will be
C(x) = (8 php)*x + 50 php.
Then the slope is 8 php, and the y-intercept is 50 php.

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.
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 the slope of a line that has a y-intercept but no x intercept
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.

This is a part of both female/ male. The male has sperm when released, and the female produces a egg which lead to reproduction.
Answer:
true
Step-by-step explanation:
The reason is that when the male and female have sex the male releases sperm into the female the sperm goes to the female egg then she gets pregnet a couple of days later. Therefore that equals reproduction.

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.

Which graph represents the function?
f(x)=2x√+1
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).

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
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.
