C. He incorrectly divided 232 by 24
C He incorrectly subtracted 192 from 232

Answer: for plato users

A is the correct answer

Step-by-step explanation:

I just took the test had 100%

The correct option is A. [tex]x^{2} -x-10=0[/tex].

Given quadratic equation  [tex]\frac{2}{3x-6} -\frac{1}{3x+6} =\frac{1}{3}[/tex]

On solving,  [tex]\frac{2(3x+6)-1(3x-6)}{(3x-6)(3x+6)} =\frac{1}{3}[/tex]

Further, [tex]\frac{6x+12-3x+6}{9x^{2} -6^{2} } =\frac{1}{3}[/tex]

[tex]\frac{3x+18}{9x^{2} -36} =\frac{1}{3}[/tex]

Taking 3 common from numerator and 9 common from denominator, we have

[tex]\frac{3(x+6)}{9(x^{2} -4)} =\frac{1}{3}[/tex]

[tex]\frac{(x+6)}{3(x^{2} -4)} =\frac{1}{3}[/tex]

[tex]\frac{x+6}{x^{2} -4} =1[/tex]

[tex]x+6=x^{2} -4[/tex]

On rearranging in decreasing powers of x we get,[tex]x^{2} -x-10=0[/tex].

Hence on solving, We get [tex]x^{2} -x-10=0.[/tex]

5.5 cm

Step-by-step explanation:

Let x be the width of the rectangle.

Since the length is double the width, the length would be 2x.

x can be found by solving the perimeter equation. The perimeter of the rectangle can be found by the equation:

[tex]p = 2(l + w)[/tex]

[tex]33 = 2(2x + x)[/tex]

[tex]33 \div 2 = (2x + x)[/tex]

[tex]16.5 = 3x[/tex]

[tex]16.5 \div 3 = x[/tex]

[tex]5.5 = x[/tex]

Therefore, the width of the rectangle is 5.5 cm.

Answer:

  D)  2 complex zeros; rational zeros among ±{1, 5, 7, 35}

Step-by-step explanation:

The signs of the coefficients of the polynomial are (+ + + +). They are all the same; there are 0 sign changes. When odd-degree terms change sign, the signs are (- + - +). There are 3 changes: -→+, +→-, -→+.

Descarte's Rule of Signs tells you the lack of sign changes among the coefficients means there are 0 positive real roots. When the signs of odd-degree terms are changed, there are then 3 sign changes, indicating 1 or 3 negative real roots and 2 or 0 complex roots.

  There are possibly 2 complex roots.

__

The Rational Root Theorem tells you any possible rational roots will be divisors of the constant term, 35. Those divisors are ±1, ±5, ±7, ±35.

  Possible rational roots are ±1, ±5, ±7, ±35.

_____

Additional comments

A graphing calculator shows the one rational root to be x=-5. The other two real roots are irrational (-3±√2). All are negative, as predicted.

__

Complex roots always come in conjugate pairs, so there will always be an even number of complex roots. This means an odd-degree polynomial will always have at least one (1) real root.

We can shorten the list of possible rational roots by remembering that there are 0 positive real roots. Then possible rational roots are -1, -5, -7, -35. In this problem, you're merely supposed to apply the rule, and not refine the result.

Changing the signs of odd-degree terms is equivalent to reflecting the function over the y-axis. That suddenly makes negative real roots into positive real roots, so the sign change rule can be applied as for positive real roots.

Answer:

y=1/3x +16/3

Step-by-step explanation:

m=(y2-y1) / (x2-x1)

   =(6-5) (2- -1)

    =1/3

Substitute in m and either point into the point slope form

y=m(x-x1) + y

y=1/3(x- -1) +5

y=1/3(x+1) +5

Now lets distribute the 1/3 to and combine the constants to put the answer in standard form

y=1/3x + 1/3 + 5

y=1/3x +1/3 + 15/3

y=1/3x +16/3

Answer:

x = 0.21

Step-by-step explanation:

[tex]\frac{.15}{100} = \frac{x}{140}[/tex]

.15(140) = 100x

21 = 100x

x = 0.21

The number of milligrams of zinc provided by 140 grams of banana will be 0.21 milligrams. Then the correct option is B.

A ratio is a collection of ordered integers a and b represented as a/b, with b never equaling zero. A proportionate expression is one in which two items are equal.

According to the department of agriculture consuming 100 grams of banana provides 0.15 milligrams of zinc.

Then the number of milligrams of zinc provided by 140 grams of banana will be given by the ratio.

Let x be the amount of zinc. Then the equation is given as,

x / 140 = 0.15 / 100

x / 1.4 = 0.15

x = 0.21 milligrams

The number of milligrams of zinc provided by 140 grams of banana will be 0.21 milligrams. Then the correct option is B.

Answer:

AC = 16.5

AE = 9

Step-by-step explanation:

Connect AC and BE

Note m∠ACD = m∠ACB, (both face arc BD)

ΔACD ~ ΔABE

AD : AB = AC : AE

6 : 4 = AC : (6 + 5)

3 : 2 = AC : 11

2AC = 3*11 = 33

AC = 16.5
