Hi!

<h3>To find the slope, use this formula</h3>

\frac{y2-y1}{x2-x1}

<h3>Put in the values</h3>

\frac{4-(-3)}{5-(-2)}=\frac{7}{7}simplify=1

<h2>The slope is 1 </h2>

Hope this helps! :)

c) If an initial investment of $ 35,000 grows to $257,000 in 15 years, what annual interest rate, continuously compounded, was e
castortr0y [4]

Answer: 13.29%

Step-by-step explanation:

The formula to calculate the compound amount (compounded continuously) is given by :-

A=Pe^{rt}, where P is the principal amount , r is the rate of interest ( in decimal) and t is the time period.

Given : P= $ 35,000 , A=  $257,000 and t=15 years

To find : r , we substitute all the values in the above formula , we get

257000=(35000)e^{15r}\\\\\Rightarrow\ e^{15r}=\dfrac{257000}{35000}\\\\\Rightarrow\ e^{15r}=7.3428

Taking natural log on both the sides , we get

15r=\ln(7.3428)\\\\\Rightarrow\ 15r=1.9937\\\\\Rightarrow\ r=\dfrac{1.9937}{15}0.132913333333\approx0.1329=13.29\%

Hence, the annual interest rate = 13.29%

A={1, 2, 3, 4, 5} e B = {2, 3, 7}, determine o conjunto A - B, ou seja, os elementos que pertencem somente a A e não a B .
Lostsunrise [7]

Responder:

A - B = {1, 4, 5}

Explicação passo a passo:

Conjunto A - Conjunto B; Isso significa que queremos um conjunto que contém apenas elementos que estão no conjunto A, portanto, os elementos do conjunto A que também estão presentes no conjunto B estão isentos.

A = {1, 2, 3, 4, 5}

B = {2, 3, 7}

A - B = {1, 4, 5}

Portanto, apenas] 1, 4, 5} são elementos do conjunto A e não do conjunto B

HELP!!!!!!!!!! PLEASE!!!!!!!WILL MARK AS BRAINLIEST
Goshia [24]

<t =33 since triangle  RUT is isosceles  (RU = TU)

<r + <u + <t = 180  triangle = 180

33 + <u + 33 = 180

66 + <u = 180

< u =114

<rus = < sut  from the diagram

<rus + <sut = <u

x + x = 114

2x = 114

divide by 2

x = 57
