The exponential function that goes through the points (0, 14) and (3, 896) is y = 14·3ˣ. This function has a base of 3 and a coefficient of 14.
An exponential function in the form y =abˣ is a function
where y is equal to a multiplied by b raised to the power of x.
To find the function that goes through the points (0, 14) and (3, 896),
We can write the following equation to find the base of the exponential function that goes through the points (0, 14) and (3, 896):
b³ = 896/14
We can then solve for b by taking the cube root of both sides of the equation to get:
b = 3
Now that we know the base of the function, we can use the point (0, 14) to find the value of the coefficient a.
Since the x-value of this point is 0, we can plug 0 in for x in the exponential function y=abˣ to get:
y = ab⁰ = a
Since the y-value of the point (0, 14) is 14, we can set this equal to a to solve for the value of a:
a = 14

What is the inverse of 7 mod 11?
The inverse of 7 modulo 11 is 4, which means that 4 multiplied by 7 gives a number congruent to 1 (mod 11). This means that 4 is the number that when multiplied by 7 gives a remainder of 1 when divided by 11.
In modular arithmetic, the inverse of a number is the number that when multiplied by the original number gives a result that is congruent to 1 (modulus). For example, if we take the modulus of 11 as an example, then the inverse of 7 modulo 11 is 4, since 7*4 = 28 ≡ 1 (mod 11). This means that 4 is the number that when multiplied by 7 gives a remainder of 1 when divided by 11. The inverse of a number modulo a given modulus can be calculated using the Extended Euclidean algorithm. This algorithm allows us to find the inverse of a number modulo a given modulus by solving a series of equations and using the result to calculate the inverse. For example, in the case of 7 mod 11, the Extended Euclidean algorithm gives us the result 4, which is the inverse of 7 mod 11.
11 = 7*1 + 4
7 = 4*1 + 3
4 = 3*1 + 1
3 = 1*3 + 0
By reading the equations from right to left, we can see that the inverse of 7 mod 11 is 4, since 4*7 = 28 ≡ 1 (mod 11).

What is the value of continuous function?
The value of a continuous function is that it produces a single output for any given input, no matter how small the change in the input. This makes it reliable and predictable, allowing for precise calculations and predictions.
Continuous functions are a type of mathematical function that produces a single output value for any given input. This means that no matter how small the change in the input is, the output value remains the same. This makes continuous functions reliable and predictable, allowing for precise calculations and predictions. As an example, a continuous function can be used to calculate how far an object will travel over a certain amount of time if provided with the initial velocity and acceleration. This is because the function will not change its output value when the input is altered, no matter how small the change is. Continuous functions are therefore an essential tool for many applications in mathematics and science.

The FLHS gil's basketball team won x games so far this season. The FLHS boy's basketball team won one more than twice as many games. Altotoguether, they won 226 games. How many games did each team win ?
The girl's basketball team won 75 games and the boy's basketball team won 151 games.
Let's assume the number of games the girl's basketball team won "g," and the number of games the boy's basketball team won "b."
We know that the total number of games won by both teams is 226, so we can set up our first equation as follows:
g + b = 226
We also know that the boy's basketball team won one more than twice as many games as the girl's basketball team. We can represent this as follows:
b = 2g + 1
Now we have two equations and two unknown values, so we can solve for g and b using algebra. Let's substitute the second equation into the first equation to eliminate one of the unknowns:
g + (2g + 1) = 226
This simplifies to:
3g + 1 = 226
Subtracting 1 from both sides gives us:
3g = 225
Dividing both sides by 3 gives us:
g = 75
Now that we know the value of g, we can substitute it back into the second equation to solve for b:
b = 2 x 75 + 1 = 151
Therefore, the girl's basketball team won 75 games and the boy's basketball team won 151 games.

find the equation of the line, help please
Answer:
y = 1x+-5
Step-by-step explanation:
The slope is going up hill so there for the slope is positive. The y-intercept is -5 bc the line crosses at -5 on the y-axis.
The graph of a sinusoidal function has a minimum point at (0,-10) and then has a maximum point at (2,-4)
Write the formula of the function, where x is entered in radians.
Answer:
f(x) = 6 * sin(2x) - 10
Step-by-step explanation:
We can use the given information to write the general formula of a sinusoidal function as follows:
f(x) = A * sin(B(x - C)) + D
The amplitude of the function, A, is equal to the difference between the maximum and minimum values of the function, which in this case is -10 - (-4) = 6.
The period of the function, B, is equal to the distance between consecutive maximum or minimum points, which in this case is 2 - 0 = 2.
The phase shift of the function, C, is equal to the horizontal shift of the entire function, which in this case is 0 since the minimum point is at x = 0.
The vertical shift of the function, D, is equal to the y-coordinate of the minimum point, which in this case is -10.
Therefore, the formula of the given function is:
f(x) = 6 * sin(2(x - 0)) - 10
We can simplify this formula by removing the unnecessary parentheses and constants:
f(x) = 6 * sin(2x) - 10
This is the final formula for the given sinusoidal function, where x is entered in radians.

times in the last 24 hours. What hour did it just finish striking?
Answer:
6 1/2 hours 12-hour clock
18 1/2 hours 24- hour clock
Step-by-step explanation:
I attached a picture of how I solved it!
The clock just crossed the 9th hour.
What is a mathematical function, equation and expression? function : In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.expression : A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.equation : A mathematical equation is used to equate two expressions.Given is that a clock that strikes only the hours has just finished striking a total of 9 times in the last 24 hours.
Since, the clock strikes only on hours, the clock just crossed the 9th hour.
Therefore, the clock just crossed the 9th hour.
