Answer:

Part 1) Triangle GHI, JKL

Part 2) (40*15)and(8*3), (18*6)and(4.5*1.5)

Step-by-step explanation:

we know that

If two figures are similar

then

the ratio of their corresponding sides are equal and is called the scale factor

Part 1)

<u>case a)</u> triangle GHI

If ABC and GHI are similar

then

\frac{4}{24}=\frac{3}{7}=\frac{5}{25}

but

0.17 \neq 0.43 \neq \ 0.20

therefore

Triangle GHI is not similar to triangle ABC

<u>case b)</u> triangle DEF

If ABC and DEF are similar

then

\frac{4}{44}=\frac{3}{33}=\frac{5}{55}

0.09=0.09=0.09

therefore

Triangle DEF is similar to triangle ABC

<u>case c)</u> triangle MNO

If ABC and MNO are similar

then

\frac{4}{10}=\frac{3}{7.5}=\frac{5}{12.5}

0.4=0.4=0.4

therefore

Triangle MNO is similar to triangle ABC

<u>case d)</u> triangle JKL

If ABC and JKL are similar

then

\frac{4}{21}=\frac{3}{20}=\frac{5}{29}

0.19 \neq 0.15 \neq 0.17

therefore

Triangle JKL is not similar to triangle ABC

Part 2)

case a) If the rectangles are similar, then

\frac{40}{8}=\frac{15}{3}

5=5

therefore

the rectangles are similar

case b) If the rectangles are similar, then

\frac{18}{4.5}=\frac{6}{1.5}

4=4

therefore

the rectangles are similar

case c) If the rectangles are similar, then

\frac{1,225}{3.5}=\frac{144}{1.2}

350\neq120

therefore

the rectangles are not similar

case d) If the rectangles are similar, then

\frac{13}{5.2}=\frac{5}{2.5}

2.5\neq 2

therefore

the rectangles are not similar

Of the 84 parents who attended a meeting at a school, 35 volunteered to supervise children during the school picnic and 11 volun
Tatiana [17]

Answer:

The number of parents who volunteered to bring refreshments is 16.

Step-by-step explanation:

The information provided is:

N = 84

n (S) = 35

n (S ∩ R) = 11

n (R) = 1.5 × n (S' ∪ R')

Compute the value of n (S ∪ R) as follows:

n(S\cup R)=n(S)+n(R)-n (S\cap R)\\\\n(S\cup R)=n(S)+[1.5(N-n(S\cup R)]-n (S\cap R)\\\\n(S\cup R)=n(S)+1.5N-1.5n(S\cup R)-n (S\cap R)\\\\2.5n(S\cup R)=n(S)+1.5N-n (S\cap R)\\\\2.5n(S\cup R)=35+(1.5\times84)-11\\\\2.5n(S\cup R)=150\\\\n(S\cup R)=\frac{150}{2.5}\\\\n(S\cup R)=60

Now compute the value of n (R) as follows:

n (R) = 1.5 \times  n (S' \cup R') \\\\n (R) = 1.5 \times  [N-n (S \cup R)]\\\\n (R) = 1.5 \times  [84-60]\\\\n(R)=16

Thus, the number of parents who volunteered to bring refreshments is 16.

In Exercise, find the derivative of the function.<br> y = 3ex - xex
nevsk [136]

Answer:

the question is incomplete, the complete question is "find the derivative of the function y=3e^{x}-xe^{x}"

answer: \frac{dy}{dx}=(2-x)e^{x}.

Step-by-step explanation:

From the equation,  y=3e^{x}-xe^{x}, we approach the question using the differentiation of a product and differentiation of a sum simultaneously,

the differentiation of a sum is express as

f(x)=u(x)+v(x)+.....w(x) then

\frac{df(x)}{dx}=\frac{du(x)}{dx}+\frac{dv(x)}{dx}+...\frac{dw(x)}{dx}.\\

For the differentiation of a product we have

 f(x)=u(x)v(x), then

\frac{df(x)}{dx}=\frac{dv(x)}{dx}u(x)+\frac{du(x)}{dx}v(x)

hence if we go by the formula we arrive at

for   y=3e^{x}

let u(x)=3 hence du/dx=0 and

v(x)=e^{x} and \frac{dv(x)}{dx}=e^{x}

hence \frac{dy}{dx}=3e^{x}+0e^{x}\\\frac{dy}{dx}=3e^{x}---equation 1\\

Also for y=-xe^{x}\\\frac{dy}{dx}=-e^{x}-xe^{x}---equation 2.

if we add equation 1 and equation 2 we arrive at

\frac{dy}{dx}=3e^{x}-e^{x}-xe^{x}\\\frac{dy}{dx}=(3-1-x)e^{x}\\\frac{dy}{dx}=(2-x)e^{x}.
