Answer:

Received a compliment: wore a tie =25

Received a compliment: did not wear a tie = 5

Did not receive a compliment: did not wear a tie =16

Did not receive a compliment: wore a tie = 9

Step-by-step explanation:

There were 11 days where she neither wore a tie nor received a compliment. This puts 11 in the bottom right box.

There were 30 days in total where she received a compliment. This means the first row (received a compliment ) adds to 30.

There were 16 days in total where she did not wear a tie. This means the second column adds to 16.

Now since there is 11 in the bottom-right box, and the right column adds to 16, this puts 16-11 = 5 into the upper-right box.

And since the upper column (received a compliment) adds to 30, the upper right column is 5, this puts 30-5 =25 into the upper left box.

What we have now is 25 in the upper-left box, 5 in upper-right box, 11 in bottom-right box.; we are missing the bottom-left box.

Since the total number of days is 50, what goes in the bottom left box is 50 - (25+5+11) = 9.

Thus we have

Received a compliment: wore a tie =25

Received a compliment: did not wear a tie = 5

Did not receive a compliment: did not wear a tie =16

Did not receive a compliment: wore a tie = 9

I need to rewrite d and h without the use of fractional or negative exponents by using radicals, how I do that???

jolli1 [7]

Answer:

The pencil marks on your page show you exactly how to do that.

Step-by-step explanation:

Take advantage of two rules of exponents:

$\sqrt[n]{x}=x^{\frac{1}{n}}\\\\x^{-n}=\dfrac{1}{x^{n}}$

$(d)\quad x^{\frac{-1}{5}}=\dfrac{1}{x^{\frac{1}{5}}}=\dfrac{1}{\sqrt[5]{x}}\\\\(h)\quad x^{\frac{-2}{11}}=\dfrac{1}{x^{\frac{2}{11}}}=\dfrac{1}{\sqrt[11]{x^{2}}}$

Find the vertex of the parabola. y= -4x^2+24x-35<br><br> Answer ASAP

exis [7]

Answer:

(3,1)

Step-by-step explanation:

y=-4x^2+24x-35

x-intercept of the vertex formula:

v=-b/2a

a=-4

b=24,

c=-35

v = - 24/2(-4)

v = -24/-8

v = 3

substitute x as v

y= -4(3)^2 + 24(3) - 35

y= -4(9) + 72 - 35

y = -36 +72 - 35

y = 36 - 35

y = 1

therefore the vertex is

(3,1)

What binomial do you have to add to the polynomial 2x^2+3y^2-5xy+1 to get the following. A polynomial that does not contain x

kiruha [24]

The Binomial $-2x^{2} + 5xy$ have to be add to the polynomial $2x^{2} +3y^{2} -5xy+1$ to get polynomial that does not contain x.

<h3>What is binomial?</h3>

A mathematical expression consisting of two terms connected by a plus sign or minus sign.

Example: x + 2 is a binomial, where x and 2 are two separate terms.

<h3>What is polynomial?</h3>

A polynomial is an expression consisting of indeterminates and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer

According to question

polynomial $2x^{2} +3y^{2} -5xy+1$

When added to binomial $-2x^{2} + 5xy$

= $3y^{2} +1$ (as $2x^{2} -5xy$ got cancelled )

and this polynomial does not contain x

Hence, Binomial $-2x^{2} + 5xy$ have to be add to polynomial $2x^{2} +3y^{2} -5xy+1$ to get polynomial that does not contain x.
