Answer:

$\large \boxed{\sf \bf \ \ x^2-6x+45 \ \ }$

Step-by-step explanation:

Hello, please consider the following.

You need to develop the expression.

$y=(x-3)^2+36\\\\=x^2-2 * 3 * x +3^2+36\\\\=x^2-6x+9+36\\\\=x^2-6x+45$

Thank you.

What is this mixed numbers fraction 413

levacccp [35]

If it is 41/3, then the answer would be 13 and 2/3. If it is 4/13, then there would be no mixed number. Sorry. It is hard to tell because there is no slash to represent where the numerator and the denominator is.

18) Value of b is : $b\geq 8$

Option A is correct.

19) Option C is correct.

Step-by-step explanation:

18) We need to find the value of b.

The given equation is:

$12b-46\geq 50$

Solving to find the value of b:

$12b-46\geq 50\\12b\geq 50+46\\12b\geq 96\\b\geq \frac{96}{12}\\b\geq 8$

So value of b is : $b\geq 8$

Option A is correct.

19) We need to find the correct graph of the equation:

$4y-2$

Solving:

$4y-2$

The values of y will be less than three. As y < 3 so, the circle on y is not filled.

So. Option C is correct.

a businesswoman sells a bag for $52.32, thereby making a profit of 9% on the cost of her. calculate the selling price the busine

Veronika [31]

Answer: $57.6

Step-by-step explanation:

Given : A businesswoman sells a bag for $52.32.

Let cuurent selling price : SP = $52.32

As they are making 9% profit now.

That means SP= Cp +0.09 CP , where Cp is the cost price of bag.

i..e $52.32=Cp(1+0.09) \ \text{[Substituted value of SP in LHS and taking Cp common outside in RHS]}$

$\Rightarrow\ 52.32=Cp(1.09)\Rightarrow\ CP=\dfrac{52.32}{1.09}=48$

i..e Cost price of bag = 48

Selling price to gain 20% profit = Cp+0.20CP

= CP(1+0.20)

=48 (1.20)

= 57.6

Hence, the selling price the businesswoman should ask in order to make 20% profit = $57.6

Answer:

$\frac{5}{6}$

Step-by-step explanation:

The total number of squares is 36, and only 6 of them are shaded therefore, the remaining 30 are not shaded. The probability that a randomly selected square is not shaded would therefore be:

$\frac{30}{36} = \frac{10}{12} \\ = \frac{5}{6}$
