If Triangle BAD is similar to Triangle DOG what do you know about the sides? Be specific.

Id say that the sides would also be similar due to SSS Theorem (Side-Side-Side) because if both triangles are similar then the sides should also be congruent

The ratio of the number of dogs the number of cats is 4:5. There are 270 animals on the rescue Farm. The number of dogs is 4/5.

mafiozo [28]

Answer:

Here is the complete question:

The ratio of the number of dogs to the number of cats is 4:5. There are 270 animals on the rescue farm. for each of the following statements, explain whether statements is true or false and why:

a. The number of dogs is 4/5 the number of cats.

b. 4/5 of the pets at the farm are dogs.

c. There are exactly 30 more cats than dogs.

d. There are exactly 30 dogs at the farm.

e. 5/9 of the pets at the farm are cats.

a,c and e are true statements.

Step-by-step explanation:

Let the number of dogs be "d' and number of cats be "c".

According to the question:

⇒ $c+d=270$ ...equation (i)

Arranging the ratio:

⇒ $\frac{4}{5} = \frac{d}{c}$

⇒ $4c=5d$

⇒ $c=(\frac{5}{4})d$ ...equation (ii)

Plugging (ii) in equation (i).

⇒ $c+d=270$

⇒ $\frac{5}{4} d+d=270$

⇒ $\frac{5d+4d}{4} =270$

⇒ $9d=270\times 4$

⇒ $d=\frac{270\times 4}{9}$

⇒ $d=120$

Number of dogs "d" = 120

Number of cats "c" = (270-120) = 150

Lets check each statement:

The number of dogs is 4/5 the number of cats.

⇒ $\frac{4}{5} \times 150$

⇒ $\frac{4\times 150}{5}$

⇒ $120$

Statement is true.

4/5 of the pets at the farm are dogs.

⇒ $\frac{4}{5} \times 270$

⇒ $216$

Number of dogs = 120

So the above statement is false.

There are exactly 30 more cats than dogs.

⇒ $c-d =30$

⇒ $150-120=30$

Statement is true.

There are exactly 30 dogs at the farm.

False, as there are 120 dogs

5/9 of the pets at the farm are cats.

⇒ $\frac{5}{9} \times 270$

⇒ $150$

Statement is true.

So,

Statement a,c and e are true as we could observe in the explanation.

Find dy/dx of y = <img src="https://tex.z-dn.net/?f=log_%7B2%7D" id="TexFormula1" title="log_{2}" alt="log_{2}" align="absmiddle

NikAS [45]

Step-by-step explanation:

$y = log_2 x^2 \\ \therefore y = \frac{log x^2}{log2}\\ (By\:change\:of\:base\:law) \\ \\ \therefore y = \frac{2log x}{log2}\\\\ differentiating \: both \: side \: w \: r \: t \: x. \\ \\ \frac{dy}{dx} = \frac{2}{log2} \bigg(\frac{d}{dx} log x \bigg) \\ \\ \therefore \frac{dy}{dx} = \frac{2}{log2} \bigg( \frac{1} {x} \times \frac{d}{dx} x \bigg) \\ \\ \therefore \frac{dy}{dx} = \frac{2}{log2} \bigg(\frac{1}{x} \times 1\bigg) \\ \\ \huge \red{ \boxed{\therefore \frac{dy}{dx} = \frac{2}{xlog2}}}$

What is the y and x? write an equation.

solong [7]

$\bf \begin{array}{ccccccccc}
&&x_1&&y_1&&x_2&&y_2\\
% (a,b)
&&(~{{ 1993}} &,&{{ 14220}}~) 
% (c,d)
&&(~{{ 1997}} &,&{{ 9780}}~)
\end{array}
\\\\\\
% slope = m
slope \implies 
\cfrac{\stackrel{rise}{{{ y_2}}-{{ y_1}}}}{\stackrel{run}{{{ x_2}}-{{ x_1}}}}\implies \cfrac{9780-14220}{1997-1993}\implies \cfrac{-4440}{4}\implies -1110$

$\bf \stackrel{\textit{point-slope form}}{y-{{ y_1}}={{ m}}(x-{{ x_1}})}\implies y-14220=-1110(x-1993)
\\\\\\
y-14220=-1110x+2212230\implies y=-1110x+2226450$
