Step-by-step explanation: First You do 200x0.10 which equals 20. then you put the cost per day first so 24 per day + the cost of all miles which is 20 at most means she can also spend less then 380 so we use the greater than equal symbol.
given g(x)=-x^2+10x-3 find the following,
g(9)
g(-1)
Step-by-step explanation:
g(x) = - x² + 10x - 3
To get the g(9) substitute X in the equation for 9
g(9) = - 9² + 10(9) -3
g(9) = 81 + 90 - 3
g(9) = 171 - 3
g(9) = 168
Similarly to get g(-1)
g(-1) = - (-1)² + 10(-1) - 3
g(-1) = - 1 - 10 - 3
g(-1) = - 14

The distance that light travels in 12.3 nanoseconds is 37.9 meters.
What is speed?
Speed is the rate of change of an object's position relative to a given frame of reference. It is a scalar quantity, meaning it has both magnitude and direction. Speed is usually measured in meters per second (m/s) or kilometers per hour (km/h). Speed is an important factor in many activities, including travel, sports, and transportation.
This can be calculated by multiplying the speed of light (3.0 x 108 m/s) by the time (12.3 nanoseconds), which yields a result of 37.9 meters. This answer is rounded to the correct number of significant figures, which is two.

The power, P (watts), of a car engine is proportional to the square of its speed,
s (m/s).
When s= 25, P = 1400.
Work out the speed (to 1 DP) when the power is 1820 watts
m/s
Answer:
28.5 m/s
Step-by-step explanation:
Given that power is 1400 W when speed is 25 m/s, and power is proportional to the square of speed, you want the speed when the power is 1820 W.
ProportionSince power is proportional to the square of speed, the ratio of speed squared to power is a constant:
s²/P = 25²/1400 = x²/1820
where x is the unknown speed.
SolutionWe can find the value of x by multiplying by 1820 and taking the square root:
x² = 25²(1820/1400)
x = 25√(1820/1400) = 25√1.3 ≈ 28.5 . . . . m/s
The speed is 28.5 m/s when the power is 1820 watts.

maya reads 6 3/4 chapters in 1 7/8 hours
what is the unit rate in chapters per hour?
write your answer as a fraction or a mixed number in simplest form
Answer:To find the unit rate in chapters per hour, we need to divide the number of chapters read by the amount of time it took to read them.
6 3/4 chapters / 1 7/8 hours = (64+3)/(18+7) chapters/hours

What is the perfect square trinomial of 36?.
A perfect square trinomial is a polynomial of the form (x + b)^2 = x^2 + 2bx + b^2. It is called a "perfect square" because when it is multiplied out, the resulting polynomial is a square of a binomial.
To find the perfect square trinomial of 36, we need to find two numbers that when added, give us b and when multiplied give us b^2=36.
Those two numbers are 6 and -6, since 6*-6 = -36 = 36.
So, the perfect square trinomial of 36 is (x + 6)(x - 6) = x^2 - 36
Another way to find the perfect square trinomial is to take the square root of the constant term (36) and then add and subtract that value to the variable.
√36 = 6
then x^2 + 6x - 6x + 36 = x^2 - 36
So, the perfect square trinomial of 36 is x^2 - 36.
[tex]36[/tex] is the square of [tex]6[/tex]. The square of a binomial is called a perfect square trinomial. [tex]X^2+12x+36[/tex] is a perfect square trinomial.
What is the inverse equation of the function, y = 3x - 6? y -1 = y -1 = x + 6 x -1 = 3 y - 6 y -1 = 3 x + 6.
The best answer (and only correct answer) among the options given is: option [C]: y⁻¹ = (x+6) / 3 .
What is the inverse function?
The inverse function returns the original value for which a function gave the output. If you consider functions, f and g are inverse, f(g(x)) = g(f(x)) = x.
Given the original function: y = 3x - 6 ;
To find the "inverse equation" of said function; we change the "x" to a y"; and the "y" to an "x"; and rewrite:
x = 3y − 6 ;
Now, rewrite in "slope-intercept form" ; or y = mx + b ;
that is, with y as "single, isolated" variable on the left-hand side of the equation (with an "implied coefficient of positive one", only); then an "equal sign, then "mx + b" ; in which: "m" is the coefficient of the variable, "x"; and in which "m" refers to the "slope"; and "b" refers to the 'y-intercept".
So, we have the inverse function:
x = 3y − 6 ; we want to write in slope-intercept form;
Add "6" to each side of the equation:
x + 6 = 3y − 6 + 6 ;
x + 6 = 3y ;
Rewrite as: 3y = x + 6 ;
Divide EACH side of the equation by "3" ; to isolate "y" one side of the equation; specifically, the left-hand side of equation; and to write in "slope-intercept form:
3y / 3 = (x + 6) / 3 ;
to get:
y = (x + 6) / 3 ;
y = (x/3) + (6/3) ;
y = (x/3 ) + 2 ;
or; write as: y = (1/3)x + 2 ;
Now, let us examine the answer choices given:
Note that all the answer choices begin with "y-1" ;
(except "answer choice: [B]" , which begins with "x-1"). This seems confusing; however, in reality, this does not mean, "y minus 1"; or "x minus 1". Rather, it mean y⁻¹ or x⁻¹ as notation for the "inverse" (not to be confused with the exponent notation. The confusion stems from the fact that it can be difficult to make such notations on the "Brainly" system.
That being said, we can write the aforementioned "rewritten equations" (see above in THIS VERY ANSWER) as:
y⁻¹ = (x + 6) / 3 ;
y⁻¹ = (x/3) + (6/3) ;
y⁻¹ = (x/3 ) + 2 ;
or; write as: y⁻¹ = (1/3)x + 2
That being said:
Therefore, the best answer (and only correct answer) among the options given is: option [C]: y⁻¹ = (x+6) / 3 .

What is the first step for solving the system using substitution results in an equation?.
The first step for solving the system using substitution results in an equation is solve one equation for either x or y.
The substitution method is a quick and easy way to algebraically solve a set of linear equations and determine the variables' solutions. According to what the name implies, this method entails determining the value of the x-variable in terms of the y-variable from the first equation and then substituting or replacing the value of the x-variable in the second equation.
We can solve and determine the value of the y-variable in this method. Finally, we may use any of the above equations to obtain x by substituting the value of y. This procedure can also be switched around so that we first solve for x before solving for y.
If we take an example ,
Equation 1: 3x + 2y = 11
Equation 2: -x + y = 3
Substituting y = 3+x in equation 1 is the first step in the equation.

Where would the intensity of an earthquake be higher?.
The intensity of an earthquake generally higher near the epicenter.
Intensity is based on observed effects of ground motion on people, buildings and natural features. This varies from site to site within the fault region, depending on the observer's position relative to the earthquake epicenter. The seismic intensity of an earthquake decreases as the distance from the epicenter increases, and decreases as the distance from the epicenter increases. An epicenter is a point on the surface of the Earth directly above where an earthquake begins. Earthquakes with a moment magnitude of approximately 6.5 or less occur in a concentrated area directly below the epicenter. Therefore, apart from the effects of different rock types and different soil types, the greatest shaking occurs at the epicenter. Earthquakes with a moment magnitude greater than 6.5 cause faults at some distance from the epicenter. At these large sizes, it is common for fractures to reach the surface. In such cases, the maximum shaking may or may not occur at the epicenter..
