Which expression gives the distance between the points (2,3) and 4,-3)?
OleMash [197]

Answer:

C

Step-by-step explanation:

The formula for finding the distance between 2 points (x1, y1) and (x2, y2) is

d = √[(x2 - x1)² + (y2 - y1)²]

Here (x2, y2) = (2, 3)  and (x1, y1) = (4, -3)

Plugging them gives us

d = √[(2 - 4)² + (3 - (-3))²]

   d = √[(2 - 4)² + (3 + 3)²]

F(x)=3x 2+x<br><br><br> Find f(−5)
Zina [86]

\huge \boxed{\mathfrak{Question} \downarrow}

  • f (x) = 3x² + x
  • Find f (-5).

\large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}

Given,

  • f (x) = 3x² + x

Now, we have to find f (-5). To find this, we just need to substitute -5 in the place of x.

So,

\sf \: f(x) =  {3x}^{2}  + x \\  \\ \sf \: \: Substitute \: x \: as \:  - 5. \\  \\ \sf \:f( - 5) = 3( - 5) ^{2}  + ( - 5) \\ \\  \sf \:Calculate \:  -5 \:  to \:  the \:  power  \: of \:  2 \:  and \:  get \:  25. \\  \\\sf \: 3\times 25+5  \\  \\ \sf \:Multiply \:  3 \:  and \:  25 \:  to \:  get \:  75. \\ \\\sf \:  75+5  \\  \\\sf \:Add \:  75 \:  and \:  5  \: to  \: get  \: 80. \\   \\  =   \boxed{\boxed{ \bf \: 80}}

Seed are often treated with fungicides to protect them in poor draining, wet environments. A small-scale trial, involving five t
Natalija [7]

Answer:

2.38%

Step-by-step explanation:

Given that:

The population size involving numbers of treated and untreated seeds N  = 10

the number of seeds that are treated which are observed = 5

the number of seeds that sprouted 'n' = 4

Now, use the method of hypergeometric probability, we have the formula:

p(y) = \dfrac{(^r_y)(^{N-r}_{n-y})}{(^N_n)}

∴

p(4) = \dfrac{(^5_4)(^{5}_{0})}{(^{10}_4)}

p(4) = \dfrac{\dfrac{5!}{4!(5-4)!}* \dfrac{5!}{0!(5-0)!}  }{\dfrac{10!}{4!(10-4)!} }

p(4) = \dfrac{\dfrac{5!}{4!}* \dfrac{5!}{(5)!}  }{\dfrac{10!}{4!(6)!} }

p(4) = \dfrac{5*1  }{210}

p(4) = 0.0238

p(4) = 2.38%
