How many times larger is 2 x 10^12 than 5 × 10^6
Answer:
[tex]4*10^5[/tex]
Step-by-step explanation:
So whenever sometimes says "how many is x larger than y", it just means what is x divided by y. For example 4 is 2 times as much as 2 because 4/2 = 2
With this being said we can simply divide two numbers
[tex]\frac{2*10^{12}}{5*10^6}[/tex]
Whenever you divide scientific notation you simply divide the two coefficients and subtract the exponents from the base 10
So: [tex]\frac{2*10^{12}}{5*10^6} =\frac{2}{5} * 10^{12-6}[/tex]
This gives you a result of: [tex]0.4 * 10^6[/tex]
Since we want the coefficient to be: [tex]1\le c < 10[/tex] we can take one of the 10s from the base, since 10^6 is just 6 tens being multiplied by each other and we can "borrow" one of them to get: [tex]0.4*10^6=0.4*10*10^5[/tex] which simplifies to: [tex]4*10^5[/tex]

EXPLANATION
irst, we have to solve the formula for cC. Subtract 32 from both sides,
[tex]\begin{gathered} F-32=\frac{9}{5}C+32-32 \\ \\ F-32=\frac{9}{5}C \end{gathered}[/tex]Then, multiply both sides by 5,
[tex]\begin{gathered} 5(F-32)=5\cdot\frac{9}{5}C \\ \\ 5(F-32)=9C \end{gathered}[/tex]And divide both sides by 9,
[tex]\begin{gathered} \frac{5}{9}(F-32)=\frac{9C}{9} \\ \\ \frac{5}{9}(F-32)=C \end{gathered}[/tex]Hence, the formula to convert from degrees Fahrenheit to degrees Celsius is C = 5/9(F - 32).
So, 59°F is equal to,
[tex]C=\frac{5}{9}(59-32)=\frac{5}{9}\cdot27=15[/tex]Hence, 59°F is equivalent to 15°C.
City workers are using a snowplow to clear a street. A tire on the snowplow is 3.2 ft in diameter and has to turn 47 times in traveling the length of the street. How long is the street?
Use the value 3.14 for π. Round your answer to the nearest tenth. Do not round any intermediate steps.
If a tire on the snowplow with a diameter of 3.2 ft turns 47 times then, the length of the street is 472.3 feet.
To clear a street the city workers use a snowplow. The diameter of the tire of the snowplow is 3.2 ft.
The tire has to turn 47 times to cover the total length of the street.
Now, we know that the circumference of a circle is given as:
C = 2πr where r is the radius of the circle. And the radius of a circle is half of its diameter.
Therefore, the circumference of the circle can be written as:
C = πD where D is the diameter of the circle.
Now, to calculate the total length of the street we will find the product of the circumference and the number of times the tire has to turn to cover the street.
Therefore,
Length of the street, L = nC
L = nπD
L = 47 × 3.14 × 3.2 ft
L = 472.256 ft
L = 472.3 ft
Hence, the length of the street is 472.3 feet.

Find the equation (in terms of x ) of the line through the points (-2,-2) and (3,-1)
Answer:
Equation of line is given as y = mx + c, where m is the gradient and c is the y-intercept.
First find the gradient.
Formula of gradient is given as (y2-y1)÷(x2-x1) or (y1-y2)÷(x1-x2)
Gradient = (-1-(-2))÷(3-(-2))
= (-1+2)÷(3+2)
= 1/5
Equation is y = 1/5 + c
Substitute either one of the points into the equation to find c.
-2 = 1/5(-2) + c
c = -8/5
Hence equation of the line is y = 1/5x - 8/5

The system of linear equations and their solutions are:
1. (51, 26): x - y = 25; 2x + 3y = 180
2. (-17, -36): x - y = 19; -2x + y/6 = 28
3. (47, 33): 2x - 3y = -5; x + y/11 = 50
4. (-31, -56): 2x - y = -6; x - 305/3 = 2y.
How to Solve a System of Equations?We can solve a system using the substitution method by finding the value of one of the variables, followed by substitution.
1. x - y = 25 -- eqn. 1
2x + 3y = 180 -- eqn. 2
Rewrite eqn. 1:
x = 25 + y
Substitute x = 25 + y into eqn. 2:
2(25 + y) + 3y = 180
50 + 2y + 3y = 180
5y = 180 - 50
5y = 130
y = 26
Substitute y = 26 into eqn. 1:
x - 26 = 25
x = 25 + 26
x = 51
The solution is: (51, 26).
2. x - y = 19 -- eqn. 1
-2x + y/6 = 28 -- eqn. 2
Rewrite eqn. 1:
x - y = 19
x = 19 + y
Substitute x = 19 + y into eqn. 2:
-2(19 + y) + y/6 = 28
-38 - 2y + y/6 = 28
-11y/6 = 28 + 38
-11y/6 = 66
-11y/6 (-6/11)= 66(-6/11)
y = -36
Substitute y = 36 into eqn. 1:
x - y = 19
x - (-36) = 19
x + 36 = 19
x = 19 - 36
x = -17
The solution is: (-17, -36).
3. 2x - 3y = -5 -- eqn. 1
x + y/11 = 50 -- eqn. 2
x + y/11 = 50
x = 50 - y/11
Substitute x = 50 - y/11 into eqn. 1
2(50 - y/11) - 3y = -5
100 - 2y/11 - 3y = -5
-35y/11 = -5 - 100
-35y/11 = -105
-35y/11(-11/35) = -105(-11/35) (multiplication property)
y = 33
Substitute y = 33 into eqn. 2:
x + 33/11 = 50
x + 3 = 50
x + 3 - 3 = 50 - 3
x = 47
The solution is (47, 33).
4. Solving the last one, we will definitely have the solution, (-31, -56).

The ball's path is that of a parabola, and the ball reaches a maximum height of 3 meters,How far from where the ball was kicked will it have a height of 2 meters? (Round your answer tothe nearest tenth.)
Given:
The distance travelled by the ball is, d = 40 m.
The maximum height the ball reached is, h = 3 m.
The objective is to find the distance travelled by the ball at a height of h' = 2 m.
. (vertex)
n, the
The value of x can be calculated using the general form of the equation of parabola,
[tex]y=a(x-p)^2+q[/tex]Here, (p,q) stands for the vertex of the parabola (20,3).
To find the value of a, consider a coordinate (0,0) and substitute the obtained values in the general equation of parabola.
[tex]\begin{gathered} 0=a(0-20)^2+3 \\ 0=a(400)+3 \\ -400a=3 \\ a=-\frac{3}{400} \end{gathered}[/tex]Now, consider the coordinate of the required distance x of the ball, (x,2).
Substitute the above coordinate, the value of a and the vertex in the equation of parabola.
[tex]\begin{gathered} y=a(x-p)^2+q \\ 2=-\frac{3}{400}(x-20)^2+3^{} \\ 2=-\frac{3}{400}(x-20)^2+3 \\ 2-3=-\frac{3}{400}(x-20)^2 \\ -1=-\frac{3}{400}(x-20)^2 \\ (\frac{400}{3})=(x-20)^2 \end{gathered}[/tex]To solve the square on RHS, take square root on both sides of the equation.
[tex]\begin{gathered} \sqrt[]{\frac{400}{3}}=\sqrt[]{(x-20)^2} \\ 11.5=(x-20) \\ x=11.5+20 \\ x=31.5\text{ m} \end{gathered}[/tex]Since, the height of 2 m of ball can be obtained at either side of the vertex.
So the distance between the vertex and the required position is
[tex]\begin{gathered} c=31.5-20 \\ c=11.5 \end{gathered}[/tex]Then, the other possible position of the ball is,
[tex]\begin{gathered} x^{\prime}=20-c \\ x^{\prime}=20-11.5 \\ x^{\prime}=8.5 \end{gathered}[/tex]Hence, the height of the ball will be 2m, either at a distance of 8.5m from origin or 31.5m from the origin.
Christopher decides that another road to be named Saturn Avenue will go past the cleaners and be perpendicular to planet drive. Determine the equation of the line that represents Saturn Avenue.
The equation of the line that represents Saturn Avenue is; y = 4.
Determine the line's equation?The equation of a line can be ascertained using the formula,
y = mx + c
where m is the line's slope and c is just the y - intercept.
m = vertical change/ horizontal change
m = Δy/Δx
m = (y₂ - y₁)/(x₂ - x₁)
In this question, draw a line through the cleaners as well as perpendicular to Planet Drive.
The point at which x = 0 is known as (0, 4).This means that the y - intercept is four.We can discover the slope of the equation by contemplating two points just on line.
Consider the following points: (8, 4) and (16, 4).
Put the value sin slope.
m = (4 - 4)/(16 - 8)
m = 0/8
m = 0
So we got that,
y - intercept = 4
slope = 0
Put back the values in equation of line.
y = mx + c
y = (0)x + 4
y = 4
As a result, y = 4 is the equation of the line which represents Saturn Avenue, given that Christopher decides that another road named Saturn Avenue, which will run past this same cleaners and be perpendicular to Planet Drive, is required.
