Answer:

○ \displaystyle x > -3 \\ 5y ≥ -4x - 10

Step-by-step explanation:

This system of inequalities has a shared portion at the origin, so we can easily jump to using the zero-interval test [test point (0, 0)] to verify the inequalities as false or true:

\displaystyle 5[0] ≥ -4[0] - 10 → 0 ≥ -10☑

\displaystyle 0 > -3☑

Plus, the top inequality has a <em>dashed </em><em>line</em><em> </em>["<" or ">"], and the bottom inequality has a solid line, so this must have an equivalence line underneath each inequality symbol ["≤" or "≥"].

** Hold on though! Although it looks obvious about what the second inequality is, we need to double-check and make sure anyway, just to be on the safe side ☺:

\displaystyle \frac{5y}{5} ≥ \frac{-4x - 10}{5} → y ≥ -\frac{4}{5}x - 2

From the y-intercept of \displaystyle [0, -2],we do \displaystyle \frac{rise}{run}by either moving four blocks <em>north</em><em> </em>over five blocks <em>west</em><em> </em>or four blocks <em>south</em><em> </em>over five blocks <em>east</em><em> </em>[<em>west</em> and <em>south</em> are negatives]. This IS what our solid graph looks like, so we are correct!

So, from all what was explained, you have your answer.

I am joyous to assist you anytime.

There are 20 members of a basketball team.
spin [16.1K]

Answer:

a)125970

b)95040

c)35640

Step-by-step explanation:

a) selecting 12 player from 20 players can be one in ^{20} C_{12}

 ^{20} C_{12} = \frac{20!}{12!X (20-12)!}

          =  \frac{20!}{12!X8!}

          = 125970

b) since each position has an identity permutations can be used so

   Number of ways = ^{12} P_{5}

                                = \frac{12!}{(12-5)!}

                                = \frac{12!}{7!}

                                = 95040

c) coach permutes 4 players for position other than centers in  ^{12}P_{4} ways and selects center in 3 ways

  so, number of ways = ^{12}P_{4}X3

                                     =\frac{12!}{8!}X3

                                     =35640

Let f(x)=x^2- 3. 1. Show that [0, 2] is a bracketing interval for f 2. Carry out 3 iterations of the bisection method applied to
Papessa [141]

Answer:

root estimate = 1.75

error bound = 0.25

Step-by-step explanation:

f is a polynomial, so it is continuous in R (real numbers). Then you can use Bolzano's theorem.

f(0) = -3.1 < 0

f(2) = 4 - 3.1 = 0.9 > 0

Then there exists c in [0, 2], for which f(c) = 0

In the bisection method you generate a sequence x_n of approximations of a root. If you have a bracketing interval [a, b], such that

f(a) and f(b) have opposite signs, then you use  approximate the root as x_n = \frac{a+b}{2}

In this case:

x_0 = 1

f(0)

Then:

x_1=1.5\\f(1.5)0\\

x_2= \frac{(1.5 + 2)}{2}= 1.75

The error bound is half the width of the interval [1.5, 2]

|error| < 0.25
