Which value of x is in the domain of f(t) = squared x - 7
zloy xaker [14]

Given:

The given function is:

f(x)=\sqrt{x-7}

To find:

The value of x that is in the domain.

Solution:

Domain is the set of input values.

We have,

f(x)=\sqrt{x-7}

We know that the square root is defined for non negative values. So,

x-7\geq 0

x\geq 0+7

x\geq 7

Thus, the domain of the given function is all real number that are greater than or equal to 7.

In the given options 0, -3, 6 are less than 7 but 8 in option A is the only value that is greater than 7. So, x=8 is in the domain of the given function.

Therefore, the correct option is A.

What is matrix X if 0.5X=A? Matrix A=[6 -12 4 6].
vladimir1956 [14]

Answer:

See attachment

Step-by-step explanation:

The given matrix equation is:

0.5X = A.

To find Matrix X, we need to multiply both sides of the equation by 2 to obtain:

2 \times 0.5X =2 \times  A

This simplifies to;

X = 2A

By scalar multiplication, we multiply each entry in the matrix A by to 2 to obtain matrix X.
