Answer:
24cm
Step-by-step explanation:
A^2 + B^2 = C^2 soo 10^ + B^ = 26^2 so 100 + B^2 = 676 subtract 100 from 676. Then take the square root of 576 and you’ll get 24. So B = 24cm
Answer: $7.50 + .99 8.50
Step-by-step explanation: 8.50 x 4 = 34 and it is close to 35.
Answer:
Step-by-step explanation:
We are given the equation of the curve:
(1)
And the equation of the line that is normal (perpendicular to that curve) in the point :
(2)
Note this equation has the form , where is the slope of the line that es normal to the curve and the intersection of that line with the y-axis.
Well, let’s begin by finding the slope of the line that is tangent to the curve by differentiating the equation (1):
(3)
Then, we have to evaluate that when (remember we are given the point ):
(4) This is the slope of the line that is tangent to the curve
And the slope of the line that is perpendicular to that tangent line is its negative reciprocal. Hence:
(5) This is the slope of the line normal to the curve
Then:
(6)
Rewritting (2):
(7)
Evaluating in the point :
(8)
Finding :
(9) This is the value of
Substituting (9) in (6):
(10)
(11) This is the value of
Real numbers are numbers that you can see on the number line. SO, it includes all the rational and irrational numbers. Irrational numbers are those that don't have an exact value. They are characterized by an infinite length of decimal places. Rational numbers can be classified as integers or fractions.
The line on top of a number stands for recurring. Recurring means that it goes on forever. They're usually on the decimal number, like 1/3 is equal to 3.33333 recurring, but you'd put a line on top of one or two threes.
