Answer:15
Step-by-step explanation:
Her mistake was forgetting that the slope is -1.02. She used (positive) 1.02 instead, leading to y = 1.02x + 7.09 = 1.02(0.5) + 7.09 = 0.51 + 7.09 = 7.6. The correct answer is C.
The line on the graph is drawn correctly, and the value of x is given as correct. If she had set y = 0.5 instead of x = 0.5, she would have come up with x = 6.46.
For the answer to the question above, I'll provide the solution to my answer below.
sin 60=h/x
<span>(3^1/2)/2=0,866 </span>
<span>5/0,866=x </span>
<span>so the answer to the problem is X=6
</span>I hope my answer helped you. Feel free to ask more questions. Have a nice day!
