The answer is the letter B
Answer:
<u><em>The value of x is 2.6</em></u>
Step-by-step explanation:
<em>Use pythagorean theorem</em>
a^2+b^2=c^2
<em>Then substitute</em>
1^2+2.4^2=c^2
<em>Then evaluate</em>
1+5.76=c^2
<em>Add</em>
c^2=6.76
<em>Isolate c by finding the sqrt of 6.76</em>
c=2.6
Answer: -50
Step-by-step explanation: (5-10) then multiply the answer by 10
Given:
The given function is:

To find:
The value of x that is in the domain.
Solution:
Domain is the set of input values.
We have,

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



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,
is in the domain of the given function.
Therefore, the correct option is A.
600km. Because 100 kilometers an hour times 6 equals a distance of 600km.
