Answer:

angle 2WZX = angle ZYX ( Since all angles and sides of a rhombus are equal)

ZYX = 2 x 29.5

4x - 10 =90 (since all angles of a rhombus intersect at 90°)

x=90+10/4

x=100/4

x=25

What is the slope of the line that passes through the points (-2, -5)(−2,−5) and (-3, -6) ?(−3,−6)? Write your answer in simples

pogonyaev

Answer:

0 & 0

Step-by-step explanation:

In order to find the answer to these two questions you need to use the slope formula, substitute, subtract, and simplify if needed.

$(-2,-5),(-2,-5) = (x^1,y^1),(x^2,y^2)$

Slope formula = $m=\frac{y^2-y^1}{x^2-x^1}$

Substitute: $\frac{-5--5}{-2--2} =$

$\frac{-5--5}{-2--2} =-5--5 = 0$

$-2--2 = -2+2=0$

$= 0$

$(-3,-6),(-3,-6)=(x^1,y^1),(x^2,y^2)$

$m=\frac{-6--6}{3--3}$

$-6+6=0$

$-3+3=0$

$=0$

Hope this helps.

A company wants to have $20,000 at the end of a ten-year period by investing a single sum now. How much needs to be invested in

Sergio039 [100]

Answer:

<h2>Principal is $6441.22 </h2>

Step-by-step explanation:

let us assume the investment is compounded over the given period

Given data

Final amount A= $20,000

Rate r= 12%= 0.12

Time t= 10 years

principal=?

The compound interest formula is

$A= P(1+r)^n^t$

Substituting our given data we have

$20000= P(1+0.12)^1^0\\20000= P(1.12)^1^0\\20000= P(3.105)\\$

Dividing both side by 3.105 to find P

$P=\frac{20000}{3.105} \\P= 6441.22$

Principal is $6441.22
