Answer:

Potencia de una potencia

La potencia de una potencia de base a es igual a la potencia de base a elevada a la multiplicación de ambos exponentes -

Potencia de base 10

En las potencias con base 10, el resultado será la unidad seguida de tantos ceros como indica la cifra del exponente

radiacion

En matemáticas, la radicación es el proceso de hallar raíces de orden n de un número a.1.

De modo que se verifica que

x n = a {\displaystyle x^{n}=a}

, donde n es llamado índice u orden, a es llamado radicando, y x es una raíz enésima.23

La raíz de orden dos de

a {\displaystyle a}

, se llama raíz cuadrada de

a {\displaystyle a}

y se escribe como

a {\displaystyle {\sqrt {a}}}

o también

a 2 . {\displaystyle {\sqrt[{2}]{a}}.}

La raíz de orden tres de

a {\displaystyle a}

, se llama raíz cúbica de

a {\displaystyle a}

y se escribe como

a 3 . {\displaystyle {\sqrt[{3}]{a}}.}

Las raíces de órdenes superiores se nombran usando números ordinales, por ejemplo raíz cuarta o raíz séptima.

La radicación es la operación inversa a la potenciación. s:

The graph of the function showing the path of a soccer ball thrown by a goalie in a video game, f(x) = –0.05x2 + 2.5x + 5.2, is

Tju [1.3M]

Answer:

The correct option is 4.

Step-by-step explanation:

The given function is

$f(x)=-0.05x^2+2.5x+5.2$

Where f(x) is height of the ball and x is the distance.

It is a polynomial function with degree 2. All polynomial functions are defined for all real numbers, therefore the mathematical domain of the function is all real numbers.

$-\infty$

Factorize the given function.

$f(x)=-0.05(x^2-50x-104)$

$f(x)=-0.05(x^2-52x+2x-104)$

$f(x)=-0.05(x(x-52)+2(x-52))$

$f(x) = -0.05 (x - 52) (x + 2)$

Put f(x)=0 to find the x intercepts.

$0 = -0.05 (x - 52) (x + 2)$

Equate each factor equal to 0.

$x=52,-2$

Therefore at x=52 and -2, the graph of f(x) intersects x-axis. Before x=-2 and after x=52 the values of f(x) is negative. Height cannot be negative, therefore reasonable domain is lie between -2 to 52.

Distance cannot be negative, therefore the reasonable domain must be positive.

$0\leq x\leq 52$

Therefore the reasonable domain is $0\leq x\leq 52$ and option 4 is correct.

Please Help I will mark brainliest !!!

Answer:

Step-by-step explanation:

If the lines are perpendicular then they will be the negative reciprocals of each other.

Calculate the slope using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = P(- 8, - 10) and (x₂, y₂ ) = Q(- 5, - 12)

$m_{PQ}$ = $\frac{-12+10}{-5+8}$ = - $\frac{2}{3}$

Repeat the process with

(x₁, y₁ ) = R(9, - 6) and (x₂, y₂ ) = S(17, - 5)

$m_{RS}$ = $\frac{-5+6}{17-9}$ = $\frac{1}{8}$

The slopes are not the negative reciprocal of each other, thus they are not perpendicular.

If you help me i will love you

You must first normalize this in order to use a Z-score table. To convert what you have into a Z score you must use this formula: (x- mean) /standard deviation. In your case (334-310)/12=2. So now you want the probability that a score is greater than 334, which in turn means you want P(Z>2)=1-P(Z<2)=1-.9772=0.0228=2.28%.
