Answer:

Step-by-step explanation:

They look about the same so it could be 54 but at the same time the angles on EDF seem bigger so it could be 63. To be one the safe side though I would choose 54.

What is overlapping set

Westkost [7]

Answer:

two sets are said to be overlapping if they contain at least one element in common A=(1,2,3,4)and B =(4,7,1,9)are said to be overlapping sets.

Step-by-step explanation:

please answer my question I answer your question

(xii) NH₂ + Cl₂ →→→→NH₂CI+ N₂

(xiv) NaOH + Cl₂ →→ NaCl + NaCIO + H₂O

" (vi) CH, + 0,— CO, + H,0

xviii) C₂H₂ + O₂2 CO₂ + H₂O

(xx) Na + H₂O → NaOH + H₂

A (xxii) PbO₂ PbO + 0₂

xxiv) NH3 + CuO →→→ → N₂ + H₂O + Cu

xxvi) H₂S + Cl₂ →→→ HCI + S

xviii) H₂S + H₂SO4 → H₂O + SO₂ + S

(xxx) C + HNO3 → CO₂ + NO₂ + H₂O

A mother invests $7000 in a bank account at the time of her daughter's birth. The interest is 18) compounded quarterly at a rate

Alex

well, from birth to your twentieth birthday that'll just be 20 years, so

$~~~~~~ \textit{Compound Interest Earned Amount} \\\\ A=P\left(1+\frac{r}{n}\right)^{nt} \quad \begin{cases} A=\textit{accumulated amount}\\ P=\textit{original amount deposited}\dotfill &\$7000\\ r=rate\to 8\%\to \frac{8}{100}\dotfill &0.08\\ n= \begin{array}{llll} \textit{times it compounds per year}\\ \textit{quarterly, thus four} \end{array}\dotfill &4\\ t=years\dotfill &20 \end{cases} \\\\\\ A=7000\left(1+\frac{0.08}{4}\right)^{4\cdot 20}\implies A=7000(1.02)^{80}\implies A\approx 34128.07$

Learning Task 4. Solve the problem by applying the sum and product of roots

Delvig [45]

Answer:

Thus, the dimensions of the metal plate are 10 dm and 8 dm.

Step-by-step explanation:

For a quadratic equation:

$x^2+bx+c=0$

The sum of the roots is -b and the product is c. Note the leading coefficient is 1.

We know the perimeter of the rectangular metal plate is 36 dm and its area is 80 dm^2. Being L and W its dimensions, then:

P=2(L+W)=36

A=L.W=80

Note both formulas are closely related to the roots of the quadratic equation, we only need to adjust the data for the perimeter to be exactly the sum of L+W and not double of it.

Thus we use the semi perimeter instead as P/2=L+W=18

The quadratic equation is, then:

$x^2-18x+80=0$
