Answer:

C. {x|x is an odd natural number between 1 and 67}

Step-by-step explanation:

B and C is also correct if the natural number is defined to be started with 1: positive integer,

but if it's defined to be non-negative real number then only C

A student would like to find the height of a statue. The length of the statue's right arm is 33 feet. The student's right arm

Xelga [282]

Answer:

The approximate height of the statue is 87.945 feet.

The approximate height of the statue is less than the actual height i.e. 88 feet 2 inches or 88.167 feet by (88.167 - 87.945) = 0.222 feet

Step-by-step explanation:

A student would like to find the height of a statue. The length of the statue's right arm is 33 feet.

The student's right arm is 2 feet long and her height is $5\frac{1}{3} = 5.33$ feet.

Now, the length of the right arm and the height must be proportional for the statue and the student.

So, $\frac{\textrm {Height of the statue}}{\textrm {Height of the student}} = \frac{\textrm {Length of right arm of the statue}}{\textrm {Length of right arm of the student}}$

⇒ $\frac{H}{h} = \frac{L}{l}$

⇒ $H = \frac{L \times h}{l} = \frac{33 \times 5.33}{2} = 87.945$ feet.

So, this approximate height of the statue is less than the actual height i.e. 88 feet 2 inches or 88.167 feet by (88.167 - 87.945) = 0.222 feet (Answer)

Find the missing endpoint if S is the midpoint RT

Stolb23 [73]

Answer:

10. T(-20, 9)

11. R(-1, -9)

12. D(-6, 5)

Step-by-step explanation:

The relationship between end points and the midpoint can be solved generically for one of the end points. That relation can be used for the different points in these problems.

<h3>generic solution</h3>

The coordinates of midpoint M is related to the coordinates of end points A and B by ...

M = (A +B)/2

This can be solved for end point B, given end point A and midpoint M:

2M = A +B

2M -A = B

Then the generic equation for end point B given end point A and midpoint M is ...

B = 2M -A

In each of the numbered problems, the midpoint and one end point are given. These can be matched with the variables in the above formula, so the solution is simply a matter of arithmetic. Beware all the minus signs.

T = 2R -S

T = 2(-9, 4) -(2, -1) = (2(-9) -2, 2(4) +1)

T = (-20, 9)

R = 2S -T

R = 2(-4, -6) -(-7, -3) = (2(-4) +7, 2(-6) +3)

R = (-1, -9)

B = (A +C)/2 = ((-9, -4) +(-1, 6))/2 = (-9 -1, -4 +6)/2 = (-10, 2)/2

B = (-5, 1) . . . . the missing midpoint of AC

D = 2B -E . . . . the missing end point of BD

D = 2(-5, 1) -(-4, -3) = (2(-5) +4, 2(1) +3)) = (-10 +4, 2 +3)

D = (-6, 5)
