It is required to find the scientific notation.
What is Scientific notation?Scientific notation is a way of writing very large or very small numbers. A number is written in scientific notation when a number between 1 and 10 is multiplied by a power of 10. Scientific Notation is the expression of a number n in the form a∗10b. where a is an integer such that 1≤|a|<10. and b is an integer too.

The height, h, in feet of a kicked soccer ball can be modeled by the function h(t) = -16t2 + 24t + 1, where t is in seconds. On its way down, the ball bounces off the crossbar of the goal, which is 8 feet above the ground. To the nearest tenth, when did the ball hit the cross bar?
Answer:
Step-by-step explanation:
let the height of a kicked soccer ball be expressed by the function:
h(t) = -16t^2 + 24t + 1 where t is in seconds
The ball hit the cross bar when the height is zero
The equation becomes
0 = -16t^2 + 24t + 1
16t^2 - 24t - 1= 0
t = 24±√24²-4(16)(-1)/2(16)
t = 24±√576+64/32
t = 24±√640/32
t = 24+25.298/32
t = 49.298/32
t = 1.54 secs
Hence the ball hit the cross bar at t = 1.6secs (to the nearest tenth)

You run 2 1/2 miles as a part of an exercise routine. You run 1/3 of that distance on a hill. You run down a slope for the last 1/2 of the hill. On how many miles of your run do you run down the slope? Write your answer as a fraction or mixed number in simplest form.
Given:
Total distance for daily exercise is [tex]2\dfrac{1}{2}\text{ miles}[/tex].
You run 1/3 of that distance on a hill.
You run down a slope for the last 1/2 of the hill.
To find:
The distance you run down the slope.
Solution:
We have,
Total distance [tex]=2\dfrac{1}{2}\text{ miles}[/tex]
You run 1/3 of that distance on a hill.
Distance on a hill [tex]=\dfrac{1}{3}\times 2\dfrac{1}{2}\text{ miles}[/tex]
You run down a slope for the last 1/2 of the hill.
Distance you run down the slope [tex]=\dfrac{1}{2}\times \dfrac{1}{3}\times 2\dfrac{1}{2}\text{ miles}[/tex]
[tex]=\dfrac{1}{6}\times \dfrac{2\times 2+1}{2}\text{ miles}[/tex]
[tex]=\dfrac{1}{6}\times \dfrac{5}{2}\text{ miles}[/tex]
[tex]=\dfrac{5}{12}\text{ miles}[/tex]
In cannot be expressed as mixed fraction because 5<12.
Therefore, the distance you run down the slope is [tex]\dfrac{5}{12}\text{ miles}[/tex].
Alejandro said that the slope of the line in the Example is because for points
2
(2, 140) and (0,0), the rise is 140 and the run is 2. Is Alejandro correct? Explain.
Answer:
Step-by-step explanation:
slope = M = rise/ run
P1=(2,140)
P2=(0,0)
M= (Y2-Y1) / ( X2-X1)
M = 0-140 /0-2
M = -140 / -2
M = 140 / 2
Yes, Alejandro is right
The slope of the line is the ratio of rise to the run. Therefore the line with points (2,140) and (0,0) has rice 140 and run 2. Hence the statement given by the Alejandro is correct.
Given information-Points of the line are (2,140) and (0,0).
The rise of the line is 140.
The run of the line is 2.
Slope of the line-
Slope of a line describes the steepness and the direction of the line. The slope of of line passing through the point [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] can be given as,
[tex]m=\dfrac{(y_2-y_1)}{(x_2-x_1)} [/tex]
Thus the slope of the line with points (2,140) and (0,0) is,
[tex]m=\dfrac{(0-140)}{(0-2)} \\ m=\dfrac{140}{2} \\ [/tex]
As the slope of the line is the ratio of rise to the run. Therefore the line with points (2,140) and (0,0) has rice 140 and run 2. Hence the statement given by the Alejandro is correct.

Questions:
1.Which expression is a factor of n^2+3n-54?
2. The trinomial x^2-14x+49 can be expressed as?
1. (n+9) • (n-6) is the answer
The required, 1. factor of the expression n²+ 3n - 54 = (n + 6)(n - 9), 2. x² - 14x + 49 can be expressed as (x - 7)².
What are the factors?A number or algebraic expression that evenly divides another number or expression—i.e., leaves no remainder—is referred to as a factor.
3.
To factor the quadratic expression n² + 3n - 54, we need to find two numbers whose product is -54 and whose sum is 3. These numbers are 6 and -9.
Therefore, we can write:
n²+ 3n - 54 = (n + 6)(n - 9)
So the expression (n + 6)(n - 9) is a factor of n² + 3n - 54.
2.
The trinomial x² - 14x + 49 can be expressed as the square of a binomial. Specifically, it is the square of (x - 7):
(x - 7)² = (x - 7)(x - 7) = x² - 14x + 49
Therefore, x² - 14x + 49 can be expressed as (x - 7)².
