can someone explain scientific notation please it’s so confusing.
Let's say we had the massive number
6,230,000,000
which we can shorten it to saying "6.23 billion" and that allows us to drop all the extra zeros at the end.
When writing it in scientific notation, we would say [tex]6.23 \times 10^9[/tex] and the [tex]\times 10^9[/tex] portion indicates "times ten to the ninth power". This is the place holder for "billion". It means we'll move the decimal point 9 spots to the right to go from 6.23 back to the original massive number shown above.
In short, scientific notation allows us to represent really large numbers in a compact way. It's useful to be able to communicate to a friend about whatever number you're referring to. One application is trying to find vast distances in outer space which tend to be very larger numbers. There are many other applications for scientific notation.
Does anyone know how to do this problem?

What is the velocity of a car that traveled a total of 75 km north in 1.5 hours
Answer:
13.89 m/s
Step-by-step explanation:
Velocity = displacement = time
75 km = 75000 m
1.5 hours = 5400 sec
applying the formula
velocity = 75000 m= 5400 s = 13.89 m/s
Answer:
Velocity= Displacement / Time
= 75/1.5
=50km/hr

Two large numbers of the Fibonacci sequence are F51 = 20,365,011,074 and F52 = 32,951,280,099.What is the approximate value of the quotient
Answer:
[tex]\frac{1+\sqrt{5} }{2}[/tex] or 1.62
Step-by-step explanation:
A cool thing about the fibonacci sequence is that if you divide two consecutive numbers, the larger they are, they approach the golden ratio. This means the approximate value would be the golden ratio which is [tex]\frac{1+\sqrt{5} }{2}[/tex].
Graph a line with a slope of 1/3 and a y-intercept of 1
Answer:
is there a image?
Step-by-step explanation:
The equation y = 0.29x + 58 models the cost y of renting a car if the car is driven x
miles.
According to the model, what is the best estimate of the cost for renting a car if you
plan to drive 619 miles? Please round your answer to the nearest dollar.
Include answer and units
Answer:
y = $238
Step-by-step explanation:
Given the equation, y = 0.29x + 58
Where:
y = total cost of renting a car
x = number of miles driven
58 = initial cost or amount.
To find the estimated cost for renting a car if you plan on driving for 619 miles, substitute 619 as the value of x into the equation:
y = 0.29(619) + 58
y = 179.51 + 58
y = 237.51 or 238
Therefore, the estimated total cost for driving 619 miles is $238.

Let f(t) represent the temperature of a turkey baking in an oven as a function of time [] in the oven (in minutes). This means time is the independent variable and temperature of the turkey t) is the dependent variable. The turkey was in the oven for 360 minutes and then removed. Note that when something is baked in an over, the temperature of the oven stays constant
1. Describe the rate of change pattern over each interval of the graph listed below.
a) 0
b) 345
c) t > 360
2. Explain what is happening in each interval of your graph in terms of the turkey and its temperature, using complete sentences
3. Let's say that the turkey sat on the counter for an additional hour (beyond the 390 minutes) and its temperature cooled to 80 degrees. Write that value in function notation
Answer:
Since x (independent) is time and y (dependent) is temperature;
F(0) =50 means; at the beginning which is 0 minutes, the temperature is 50F
f(120)>f(60) means the temperature after 120 min is bigger than the temperate after 60 min.
f(360) = f(345) means the temperature after 360 min and 345 min are the same
f(390) < f(360) means the temperate after 390 min is less than the temperature after 360 min
Step-by-step explanation:
Answer:
Since x (independent) is time and y (dependent) is temperature;
F(0) =50 means; at the beginning which is 0 minutes, the temperature is 50F
f(120)>f(60) means the temperature after 120 min is bigger than the temperate after 60 min.
f(360) = f(345) means the temperature after 360 min and 345 min are the same
f(390) < f(360) means the temperate after 390 min is less than the temperature after 360 min

Find the midpoint M of the line segment joining the points S = (7, -2) and T = (-3, -8).
Answer:
(2, -5)
Step-by-step explanation:
Using the midpoint formula - M= [tex](\frac{x_{1} +x_{2} }{2}, \frac{y_{1}+y_{2} }{2} )[/tex], we get that the x value of the point is 2 and the y-value of the midpoint is -5, so the midpoint of segment ST is (2, -5)

Given s = 2.4 b = -7.2 t = 4.8 n = -9.6, evaluate this mathematical expression (s - b)(n + t).
These are the answer options:
23.04
-23.04
46.08
-46.08
Answer: Fourth Choice. -46.08
Concept:
Here, we need to understand the idea of evaluation.
When encountering questions that gave you an expression with variables, then stated: "If x = a, y = b, z = c" (a, b, c are all constants), this means you should substitute the value given for each variable back to the expression.
Solve:
Given information
s = 2.4
b=-7.2
t=4.8
n=-9.6
Given expression
(s - b) (n + t)
Substitute values into the expression
= (2.4 - (-7.2)) (-9.6 + 4.8)
Simplify values in the parentheses
= (2.4 + 7.2) (-4.8)
=(9.6) (-4.8)
Simplify by multiplication
= [tex]\boxed{-46.08}[/tex]
Hope this helps!! :)
Please let me know if you have any questions
Answer:
- 46.08Step-by-step explanation:
Given Values :-
s = 2.4
b = - 7.2
t = 4.8
n = - 9.6
Substituting the given values in the equation :-
= > ( s - b ) ( n + t )
= > ( 2.4 - ( - 7.2 ) ) ( - 9.6 + 4.8 )
= > ( 2.4 + 7.2 ) ( -4.8 )
= > ( 9.6 ) ( - 4.8 )
= > - 46.8

What’s mean number basic statistics btw
Answer:
To find the mean, add up the values in the data set and then divide by the number of values that you added. To find the median, list the values of the data set in numerical order and identify which value appears in the middle of the list. To find the mode, identify which value in the data set occurs most often.

Step-by-step explanation:
31) Multiply the entire equation by the LCM of 5 & 4 which is 20
[tex]20*\dfrac{2x^{2}}{5}+20*\dfrac{5x}{4}=10*20\\\\4*2x^{2}+5*5x = 200\\\\8x^{2}+25x - 200 = 0[/tex]
B
32) D
By trial & error method 17 * 15 = 255
33) x = 2
y = 4x² + 1
= 4*2² + 1 = 4*4 + 1
= 16 + 1
y = 17
B
34) D) all real numbers
35) Domain = all real numbers,
x = -2 ; y = -(-2+2)² - 7 = 0 - 7 = - 7
x = 0 ; y = -(0+2)² - 7 = -4 - 7 = -11
x = 4; y = -(4+2)² - 7 = - 6² -7 = -16 - 7 = - 23
C) y ≤ -7
36) t = 1 second
y = 160t - 40t² = 160*1 - 40*1² = 160 - 40
y = 120 m
C
37) Let the number be 'x'
x² + x = 165
x² + 4x - 165 = 0
Sum = 4
Product = -165
Factors = 15 , -11 {15*(-11) = -165 & 15+ (-11) = 4}
x² + 15x - 11x - 165 = 0
x(x + 15) - 11(x + 15)=0
(x + 15)(x - 11) = 0
x + 15 = 0 ; x - 11 = 0
x = -15 ; x = 11
C
38) y = 3(x + 1)² - 2
Plugin x = -1 ; y = 3(-1 +1)² - 2 = 0 - 2
y = -2
(-1 , -2)
D
39) y = 3(x - 9)² + 3
Plugin x = 9 ; y = 3(9-9) + 3 = 0 + 3 = 3
