Answer:
C
Step-by-step explanation:
5x 2nd power -(-4x 2nd power) makes it a positive which is 9x 2nd power then 9x 2nd power +(-3x 2nd power) which + and - make it 9x 2nd power-3x 2nd power which equals 6x 2nd power. The only answer choice with 6x 2nd power is C.
A = l²
A = 7.2²
A = 51.84
51.84 inches
Answer:
3 cubic inches
Step-by-step explanation:
Using the formula, the volume of a cone
Subst. the known value of into the equation.
Thus, the volume of cone= 1(3)= 3 cubic inches.
Because bases are different.
a^n · a^m = a^(n+m)
Given statement 'a local variable is a variable defined inside a function that can only be used inside its function' is False
A local variable is a type of variable that we declare inside a block or a function, unlike the global variable. They can be used only by the statements that are inside the function or the block of the code. Local variables are not known to functions outside their own.
The variable declared is local within that function that is the declared variable is accessible inside that block itself, it cannot be accessible outside the given function.
Consider the following multiplication function:
ex - void multi()
{
int a = 10, b = 2, c ;
c = a * b ;
cout << c ;
}
int main()
{
cout << "value for c is :"<< c ;
return 0;
}
Here inside the multi function variable a, b, c are declared and initialized inside the function.
Thus, a local variable is defined inside the body of the function and is not accessible outside of the function.
Therefore, given statement 'a local variable is a variable defined inside a function that can only be used inside its function' is False
