Find the sum of 1st 18 terms of an AP whose nth term is 3-2n.

cricket20 [7]

Answer:

-288

Step-by-step explanation:

<h3>Given AP</h3>

t(n) = 3 - 2n

The sum of first 18 terms

<h3>Solution</h3>

Sn = 1/2n(t(1) + t(n))

<u>The first and 18th terms as per the formula</u>

t(1) = 3 - 2 = 1
t(18) = 3 - 18*2 = 3 - 36 = -33
S18 = 1/2*18(1 - 33) = 9*(-32) = -288

<u>Answer is</u> -288

Find the missing length for a right triangle with hypotenuse of 18 and a leg length of 6. Round to the nearest whole number if n

DiKsa [7]

$a^2 + b^2 = c^2$

$a^2 + 6^2 = 18^2$

$a^2 + 36 = 324$

$a^2 = 288$

$a = \sqrt{288}$

$a = \sqrt{144 \times 2}$

$a = 12\sqrt{2}$

$a \approx 17$

Given a regular square pyramid with RS = 6 and PX = 4, find the following measure.<br><br> PY =

Dennis_Churaev [7]

Answer:

$PY=5\ units$

Step-by-step explanation:

we know that

Applying the Pythagoras Theorem

$PY^{2}=PX^{2}+XY^{2}$

In this problem we have that

$XY=RS/2=6/2=3\ units$

$PX=4\ units$

substitute

$PY^{2}=4^{2}+3^{2}$

$PY^{2}=25$

$PY=\sqrt{25}\ units$

$PY=5\ units$
