Which equation represents y = -x2 - 2x + 3 in vertex form?

Georgia [21]

Answer:

y = -(x + 1)² + 4

Step-by-step explanation:

y = -x² − 2x + 3

First, factor the leading coefficient from the first two terms.

y = -(x² + 2x) + 3

Complete the square.

y = -(x² + 2x + 1 − 1) + 3

Simplify and factor.

y = -(x² + 2x + 1) + 1 + 3

y = -(x + 1)² + 4

Find the number of sides for a regular polygon whose interior angles each measure 10 times each exterior angle

gavmur [86]

Answer:

22 sides

Step-by-step explanation:

The expression to find an interior angle of a polygon is:

$\frac{(n-2)*180}{n}$

The expression to find an exterior angle of a polygon is:

$\frac{360}{n}$

Please note that "n" represents the number of sides the polygon has.

We can use these two expressions to set up an equation.

$\frac{(n-2)*180}{n}=10(\frac{360}{n})$

Multiply both sides by "n":

$(n-2)*180=10n(\frac{360}{n})$

Now, distribute:

$180(n)-180(2)=\frac{3600n}{n}\\180n-360=3600$

Divide both sides by 10:

$\frac{180n}{10}-\frac{360}{10}=\frac{3600}{10}\\$

$18n-36=360$

Add 36 to both sides:

$18n=360+36\\18n=396$

Divide both sides by 18:

$n=22$

The polygon has 22 sides

Square P and Sqare Q are similar squares. The ratio of the side length of square P to the side length of square Q is 2:7. If the

Sergeu [11.5K]

Answer:

Perimeter of square Q is 49 inches.

Step-by-step explanation:

Let x be the length of side of square P and y be that of square Q.

It is given in the question that :

$\frac{x}{y}=\frac{2}{7}$

Also it is given that x=3.5 inches.Hence

$\frac{3.5}{y}=\frac{2}{7}$

∴ y=12.25 inches.

Perimeter of square Q is 4y = $4\times12.25=49$ inches.

Guys!!! I need help ASAP!!!!

<h2><u>Solution 1</u> :</h2>

Cost of $1\frac{1}{3}$ pounds of gummy bears = $4.40

Cost of 1 pound of gummy bears :

$= 4.40 \div 1 \frac{1}{3}$

$= \frac{440}{100} \div \frac{4}{3}$

$= \frac{440}{100} \times \frac{3}{4}$

$= \frac{1320}{400}$

$= \frac{1320 \div 20}{400 \div 20}$

$= \frac{66}{20}$

$= \frac{66 \div 2}{20 \div 2}$

$= \frac{33}{ 10 }$

$= 3 \frac{3}{10}$

$= \color{plum}\bold{\$3.3}$

Therefore, 1 pound of gummy bears = <u>$3.3</u>

<h2><u>Solution 2</u> : </h2>

Cost of 1 pound of gummy bears = $3.3

Money Daniel has = $1.00

Quantity of gummy bears he can afford :

$= 1 \div 3.3$

$= 1 \div 3 \frac{3}{10}$

$= 1 \div \frac{33}{10}$

$= 1 \times \frac{10}{33}$

$= \frac{10}{33}$

$= 0.30$

Therefore, Daniel will be able to buy <u>0.30 pounds</u> of gummy bears from Jio.
