Answer:
- b = 15
- c = 51
- c = 100
- b = 25.75
Step-by-step explanation:
Using the Pythagoras theorem equation:

Where 'c' is the hypotenuse and 'b' and 'a' the sides of the right triangle.
1) Here c = 17, a = 8 and b = ?
Then, using the above equation we can find the side b.


2) Here a = 24, b = 45 and c = ?

3) Here a = 28, b = 96 and c = ?
4) Here a = 17, b = ? and c = 28

Just in the 4 case x is an altitude.

Answer:
16
Step-by-step explanation:
The perpendicular diameter to the chord divides it into two congruent parts.
Since
we have that XT=TS.
Hence,
3b-1=b+5,
3b-b=5+1,
2b=6,
b=3.
So,
XT=3·3-1=9-1=8
TS=3+5=8
and
XS=XT+TS=8+8=16.
The length of the parametric curve (call it <em>C </em>) is given by

We have


Now,

so that the arc length integral reduces to

which has an approximate value of 53.4596.
Answer:
Axioms or postulates are universal truths. They cannot be proved. Theorem are statements which can be proved.
Simple interest doesn't compound, so we just find the interest she needs by dividing 4,000 by 8, and then divide that number by her principal to find the rate of interest.
4,000 ÷ 8 = 500
She needs 500 dollars per year in interest.
800 ÷ 14,100 = .0355 = 3.55%
Answer is B
