What is the formula for finding a1 in the geometric series sn=48455, r=3.2, n=3?

Answers

Answer 1

Answer: The formula for finding the sum in the geometric series: $S_(n)=a_(1) * ( r^(n) -1)/(r-1)$ For finding a1: $a_(1) = ( S_(3)*(3.2-1) )/( 3.2^(3)-1 ) = (48455*2.2)/(32.768-1)= (106601)/(31.768)=3355.6094$

using the autonomous equation 2 discuss how it is possible to obtain info about the llocation of points of inflection

Answers

Answer:

The autonomous equation refers to a differential equation where the independent variable is absent. In such equations, the information about the location of points of inflection can be obtained by analyzing the second derivative of the equation. Points of inflection occur where the second derivative changes sign. By finding the critical points of the second derivative and determining their nature (whether they are minima, maxima, or points of inflection), we can identify the location of points of inflection.

Triangle PQR has vertices P(0, 0), Q(3, 4), and R(3, 0). If triangle PQR is rotated 180° about the origin, what is the length of side P'Q'?

Answers

Answer:

The length of P'Q' is 4 units

The length of P'R' is 3 units

Step-by-step explanation:

If you rotate the figure 180° then the vertex would be R, and from P to Q is 3 units left and 4 units down

Final answer:

To find the length of side P'Q' after rotating triangle PQR 180° about the origin, we need to find the distance between the points P'(0,0) and Q'. When you rotate a point (x, y) 180° about the origin, the new coordinates are (-x, -y). Using the distance formula, we can find the length of side P'Q': d = sqrt((-3-0)^2 + (-4-0)^2) = sqrt(9 + 16) = sqrt(25) = 5. Therefore, the length of side P'Q' is 5 units.

Explanation:

To find the length of side P'Q' after rotating triangle PQR 180° about the origin, we need to find the distance between the points P'(0,0) and Q'.

When you rotate a point (x, y) 180° about the origin, the new coordinates are (-x, -y).

So, the coordinates of point Q' would be (3, 4) rotated 180°, which is (-3, -4).

Using the distance formula, we can find the length of side P'Q':

d = sqrt((-3-0)^2 + (-4-0)^2) = sqrt(9 + 16) = sqrt(25) = 5.

Therefore, the length of side P'Q' is 5 units.
