Which set of parametric equations represents the following function y=square root of x+3
Irina18 [472]
The given equation is:

y= \sqrt{x+3}

We have to find, which of the given set of parametric equations given in the options, result in the above equation:

The correct answer would be option A.

The equations in option A are:

x(t) = 5t \\ 
y(t)= \sqrt{5t+3}

From first equation we can see that 5t is equal to x. Using the value of 5th in second equation, we get the equation as:

y= \sqrt{x+3}

Therefore, the correct answer is option A

What is the sum of the geometric sequence 3,15,75... if there are 7 terms ?
FinnZ [79.3K]

Answer:

58593

Step-by-step explanation:

The sum to n terms of a geometric sequence is

S_{n} = \frac{a(r^n-1)}{r-1}

where a is the first term and r the common ratio

r = 15 ÷ 3 = 75 ÷ 15 = 5 and a = 3, hence

S_{7} = \frac{3(5^7-1)}{5-1}

= \frac{3(78125-1)}{4} = \frac{3(78124)}{4} = 58593
