Find the equation of a line passing through the point (1, 1) and having a slope of 3.

maks197457 [2]

<u>Given</u>:

The equation of the line passes through the point (1,1) and having a slope of 3.

We need to determine the equation of the line.

<u>Equation of the line:</u>

The equation of the line can be determined using the formula,

$y-y_1=m(x-x_1)$

Substituting the point (1,1) and the slope m = 3 in the above formula, we get;

$y-1=3(x-1)$

Simplifying the terms, we get;

$y-1=3x-3$

Adding both sides of the equation by 1, we get;

$y=3x-2$

Thus, the equation of the line is $y=3x-2$

Hence, Option C is the correct answer.

given that a1=5 and a2=15 are the first two terms of a geometric sequence, determine the values of a3 and a10. Show the calculat

Alekssandra [29.7K]

a_3 is 45 and a_10 is 98415

Step-by-step explanation:

Given

a_1 = 5

a_2 = 15

First of all we have to calculate the common ratio of the sequence. The common ratio is the ratio between two consecutive terms of a geometric sequence.

So,

$r=\frac{a_2}{a_1} = \frac{15}{5} = 3$

The explicit formula for geometric sequence is:

$a_n = a_1.r^{n-1}$

Putting the value of r and a_1

$a_n = 5.(3)^{n-1}$

Putting n=3 in the explicit formula

$a_3 =5.3^{3-1}\\= 5 * 3^2\\=5 * 9\\= 45$

Putting n=10 for tenth term

$a_{10} =5.3^{10-1}\\=5*3^9\\=5 * 19683\\=98415$

Hence,

a_3 is 45 and a_10 is 98415
