Answer:
C. 
Step-by-step explanation:
Let be the parametric equations 
and 
, we need to clear 
and eliminate it afterwards to obtain a function of the form 
:
(1)
(2)
By (1) and (2):
Hence, the correct answer is C.
The numerical value of 70,000 is in standard form.
Answer:
The fee increased 12.5%
Step-by-step explanation:
The new price is 9 and the old price is 8, so you can find the change by doing
9/8
which is 1.125
This means the new price is 12.5% higher than last year because you have to ignore the 1 in front and only look at the .125
Move the decimal place two to the right to get 12.5 and then add the % sign.
Solutions
To solve this problem we have to use the Pythagorean theorem. You can only use the Pythagorean theorem in Right Triangles. The longest side of the triangle is called the "hypotenuse". C² is the longest side so it is the hypotenuse . To calculate c² we have to do α² + β² = c².
Given
One leg of a right triangular piece of land has a length of 24 yards. They hypotenuse has a length of 74 yards. The other leg has a length of 10x yards.
First leg (24 yards) would be α
Second leg would be β
Hypotenuse (74 yards) would be c
Now we have points α β c.
a² (24) + β² ( x ) = c² (74)
Calculations
c² = α² + β²
74² = 24²+ β²
<span>5476 = 576 + </span>β²
5476 - 576 = β²
<span> </span>
<span>4900 = </span>β²
→√4900
<span> </span>
β<span> = 70 yards
</span>
<span>70 = 10x
</span>
<span>x = 70</span>÷<span>10 = 7 yards
</span>
The second leg = 7 yards
180/3=60
Now lets find out what x is the get 5x+10 to equal 60.
Just looking at it, its D.....x=10
5(10)+10
50+10=60
