<span>(3k^2+2)(k+5^2)
so first simplify the 5^2 = 25

so </span><span>(3k^2+2)(k+25)
now open the brackets :
3k^3 + 75k^2 + 2k + 50

are you sure that the question has been copied exactly? as none of the options are correct in this case </span>

Answer:

Step-by-step explanation:

$Use\\\\a^n\cdot a^m=a^{n+m}\\\\\dfrac{a^n}{b^n}=\left(\dfrac{a}{b}\right)^n\\=================\\A.\ 3^{x+1}=3^x\cdot 3\neq3^x\\\\B.\ 3\cdot3^{x-1}=3\cdot3^x\cdot3^{-1}=(3^1\cdot3^{-1})\cdot3^x=3^{1+(-1)}\cdot3^x=3^0\cdot3^x=1\cdot3^x=3^x\\\\C.\ \dfrac{18^x}{3}\neq3^x\\\\D.\ \left(\dfrac{18}{6}\right)^x=(3)^x=3^x\\\\E.\ x^3\neq3^x\\\\F.\ \dfrac{18^x}{6^x}=\left(\dfrac{18}{6}\right)^x=(3)^x=3^x$

An integer is chosen random between 1 to 100. find the probability that it is divisible by 8

arlik [135]

Answer: 0.12

x is the number which is chosen

The number of ways to choose x from 1 to 100 is 100 (ways)

because x is divisible by 8 => x ∈ {8; 16;...; 96}

=> the number of terms divisible by 8 from 1 to 100 is (96 - 8)/8 + 1 = 12

the number of ways to choose x which is divisible by 8 is 12 (ways)

=> the probability that x is divisible by 8 is 12/100 = 0.12

Verizon [17]

Answer:

c. Weight is input, height is output

Step-by-step explanation:

It is given here that "Height is a function of Weight".

which means

$Height = f(Weight)$

Thus, value of Height is depend on the value of Weight.

Thus, Weight is input variable and Height is output variable.

Hence option (c) is correct.

Further,

The variable that we can change is called the Input variable.

The Output variable depends upon the input variable, as we change the value of the input variable the value of the output variable is also get changed.
