37th term; a1 = 2.3; d = -2.3

Sindrei [870]

Answer:

37th term of given arithmetic sequence $a_1$ = 2.3; d = -2.3 is -80.5.

Solution:

Given that

Need to determine 37th term, when $a_1$ = 2.3, d = -2.3

Means first term of arithmetic sequence = $a_1$ = 2.3 and common difference d = -2.3

Formula for nth term of arithmetic sequence is

$\mathrm{a}_{\mathrm{n}}=\mathrm{a}_{1}+(\mathrm{n}-1) \mathrm{d}$ --- equation 1

$\text { In our case } a_{1}=2.3, d=-2.3$

We need to determine 37th term so n = 37.

On substituting given values in equation (1) we get

$\mathrm{a}_{37}=\mathrm{a}_{1}+(37-1) \mathrm{d}$

$\begin{array}{l}{\Rightarrow a_{37}=2.3+(37-1)(-2.3)} \\\\ {\Rightarrow a_{37}=2.3(1-36)=2.3 \times 35=-80.5}\end{array}$

Hence 37th term of given arithmetic sequence is -80.5

A home-based sign company uses this function to model its monthly profit, where x is the price of each sign it sells.

kifflom [539]

Answer:

$p(20) = 4460$

Step-by-step explanation:

Given

$p(x) = -10x^2 + 498x - 1500$

Required

Evaluate p(x) when x = 20

To do this, we simply substitute 20 for x

$p(x) = -10x^2 + 498x - 1500$

$p(20) = -10 * 20^2 + 498 * 20 - 1500$

$p(20) = -10 * 400 + 9960 - 1500$

$p(20) = -4000 + 9960 - 1500$

$p(20) = 4460$

Determine which of the following are equivalence relations and/or partial ordering relations for the given sets: A = { lines in

VLD [36.1K]

Answer:

Check the explanation

Step-by-step explanation:

a) A is an Equivalence Relation

Reflexive : x is parallel to itself => x R x

Symmetric : x is parallel to y => y is parallel to x.

Therefore x R y => y R x

Transitive : x is parallel to y and y is parallel to z then x, y, z are parallel to each other.

=> x R y and y R z => x R z

Therefore A is equivalent.

1. b)

x r y if and only if |x-y| less than or equal to 7

Reflexive : |x-x| = 0 <= 7 => x R x Satisfied.

Symmetric : let x R y => |x-y| <= 7

Consider |y-x| = |(-1)*(x-y)| = |x-y| <= 7

=> y R x => Satisfied

Transitive : let x R y and y R x

=> |x-y| <= 7 and |y-z| <= 7

but this doesn't imply x R z

Counter-Example : x = 1, y = 7, z = 10

Therefore this relation is neither Equivalent nor Partial Order Relation.

What is the approximate measure of I

mrs_skeptik [129]

Let θ = m∡I

tan θ = 20/21
tan⁻¹ (20/21) = θ

θ ≈ 43.60° or if you need to round to another decimal point, plug the equation I put in bold into a calculator.
