Use the function below to find F(2)<br> F(x)=1/3•4^x<br> A.)2<br> B.)4<br> C.)8/3<br> D.)16/3
inna [77]

Answer:

D

Step-by-step explanation:

The function F(x) = \frac{1}{3}*4^x has value F(2) when x = 2 is substituted.

F(x) = \frac{1}{3}*4^x\\F(2) = \frac{1}{3}*4^2\\F(2) = \frac{1}{3}*16\\F(2) = \frac{16}{3}

What is the slope of the line joining (8,8) and (12, 6)?
Anna71 [15]

Answer:

\huge \boxed{ \boxed{ -  \frac{1}{2} }}

Step-by-step explanation:

The slope of a line given two points can be found by using the formula

m =  \frac{ y_2 - y _ 1}{x_ 2 - x_ 1} \\

From the question we have

m =  \frac{6 - 8}{12 - 8}  =  -  \frac{2}{4}  =  -  \frac{1}{2}  \\

We have the final answer as

-  \frac{1}{2}  \\

Hope this helps you

Se sabe q la suma de tres numeros es de 850. El primer es un tercio del segundo y el tercer número es el doble del segundo.¿Cual
murzikaleks [220]

Answer:

Primer número = x = 85

Segundo número = y = 255

Tercer número = z = 510

Step-by-step explanation:

Se sabe que la suma de tres números es 850. El primero es un tercio del segundo y el tercer número es el doble del segundo.

Representamos:

Primer número = x

Segundo número = y

Tercer número = z

Se sabe que la suma de tres números es 850.

x + y + z = 850 ...... Ecuación 1

El primero es un tercio del segundo

x = 1/3 años

El tercer número es el doble del segundo.

z = 2 años

Sustituimos 1 / 3y por x y 2y por z en la Ecuación 1

1 / 3y + y + 2y = 850

y / 3 + 3y = 850

Multiplica ambos lados por 3

y + 9y = 850 × 3

10 años = 2550

y = 2550/10

y = 255

Resolviendo para x

x = 1/3 años

x = 1/3 × 255

x = 85

z = 2 años

z = 2 × 255

z = 510

Por eso,

Primer número = x = 85

Segundo número = y = 255

Tercer número = z = 510
