The perimeter of an isosceles triangle is 15.6 m. Find the lengths of its sides, if: Chapter Reference a The base is 3 m smaller
SSSSS [86.1K]

We know that an isosceles triangle has 2 equal sides.

We can represent the equal sides with x, and the base with y:

2x + y = 15.6

Given states that y = x - 3, so:

2x + x - 3 = 15.6

3x = 18.6

x  = 6.2

y = 3.2

The sides are 6.2 m, and the base is 3.2 m.

Find <img src="https://tex.z-dn.net/?f=a_%7B1%7D" id="TexFormula1" title="a_{1}" alt="a_{1}" align="absmiddle" class="latex-form

Answer:

\displaystyle  a_{1}    = 108

Step-by-step explanation:

we are given

the sum,common difference and nth term of a geometric sequence

we want to figure out the first term

recall geometric sequence

\displaystyle S_{ \text{n}} =  \frac{ a_{1}(1 -  {r}^{n} )}{1 - r}

we are given that

  • S_n=189
  • r=\dfrac{1}{2}
  • n=3

thus substitute:

\displaystyle 189=  \frac{ a_{1}(1 -  {( \frac{1}{2} )}^{3} )}{1 -  \frac{1}{2} }

to figure out a_1 we need to figure out the equation

simplify denominator:

\displaystyle  \frac{ a_{1}(1 -  {( \frac{1}{2} )}^{3} )}{ \dfrac{1}{2}  }  = 189

simplify square:

\displaystyle  \frac{ a_{1}(1 -  {( \frac{1}{8} )}^{} )}{ \dfrac{1}{2}  }  = 189

simplify substraction:

\displaystyle  \frac{ a_{1} (\frac{7}{8} )}{ \frac{1}{2}  }  = 189

simplify complex fraction:

\displaystyle   a_{1} (\frac{7}{8} ) \div { \frac{1}{2}  }  = 189

calculate reciprocal:

\displaystyle   a_{1} \frac{7}{8}   \times 2  = 189

reduce fraction:

\displaystyle   a_{1} \frac{7}{4}   \  = 189

multiply both sides by 4/7:

\displaystyle   a_{1} \frac{7}{4}  \times  \frac{4}{7}   \  = 189 \times  \frac{4}{7}

reduce fraction:

\displaystyle   a_{1}     = 27\times  4

simplify multiplication:

\displaystyle  a_{1}    = 108

hence,

\displaystyle  a_{1}    = 108

250tThe population of Sasquatch in Salt Lake County was modeled by the function P(t)wheret + 25t = 0 represents the year 1803. W
jeyben [28]

Solution

Given the population function to be;

P(t)=\frac{250t}{t+25}

When P(t) = 150

\begin{gathered} \Rightarrow\frac{250t}{t+25}=150 \\  \\ \Rightarrow250t=150(t+25) \\  \\ \Rightarrow250t=150t+3750 \\  \\ \Rightarrow250t-150t=3750 \\  \\ \Rightarrow100t=3750 \\  \\ \Rightarrow t=37.5\approx38 \end{gathered}

1803 + 38 = 1841.
