1 foot = 12 inches.
Divide total inches by 12 to convert to feet:
59 inches / 12 inches per foot = 4.91666 feet
Round to 4.92 feet.
Answer:
XOC = 60
Step-by-step explanation:
AOC = DOB because they are vertical angles
AOX+XOC = 25+45
10+XOC = 70
XOC = 70-10
XOC = 60
Answer:
y = 6x − 11
Step-by-step explanation:
x = t + (1/t), y = t² + (1/t²)
If we square x:
x² = t² + 2 + (1/t²)
x² = y + 2
When x = 3, y = 7.
Taking derivative with respect to time:
2x = dy/dx
dy/dx = 6
So the equation of the tangent line is:
y − 7 = 6 (x − 3)
y − 7 = 6x − 18
y = 6x − 11
Answer:
x = -1
Step-by-step explanation:
<em><u>Add like terms (3 and 7, 2x and -10x and -x)</u></em>
x + 3 + 7 = 2x - 10x - x
x + 10 = -9x
<em><u>Subtract x from both sides:</u></em>
10 = -10x
<em><u>Divide both sides by -10:</u></em>
-1 = x
