Help plz it’s algebra 2 vertex forms of quadratic function

Answer:

Yes because the y value is 0 thus the ordered pair is located on the x - axis

Step-by-step explanation:

Answer:

1) A = 80

2) A = 30

Step-by-step explanation:

1) x+50 + 80 + x + 70 = 180

2x+120 = 180

2x = 60

x=30

A = (30) + 50

A = 80

2) x+40 + x+90 + (180-110) = 180

x+40 + x+90 + 70 = 180

2x + 200 = 180

2x = -20

x = -10

A = (-10) + 40

A = 30

Answer: B = [tex]\frac{-c}{a}[/tex] + [tex]\frac{d}{a}[/tex]

Step-by-step explanation:

you need to get B alone so that would be subtracting everything around it

ab = -c + d

then you need to get that a away from it by dividing both sides by A

B = [tex]\frac{-c}{a}[/tex] + [tex]\frac{d}{a}[/tex]

Answer:

175.79* .0825 = 14.50 + 175.79 =  190.29 $190.25

Step-by-step explanation:

The amount of sales tax Samuel will pay is $14.50

Given the following information

Get the amount of sales tax:

Amount of sales tax = 8.25% of $175.79

Amount of sales tax = 0.0825 * 175.79

Amount of sales tax = $14.50

Hence the amount of sales tax Samuel will pay is $14.50

The sequence for the derivation of tangent sum identity is option I --> IV --> II --> III.

The trigonometric identities is the relationship between the different trigonometric ratios. These trigonometric identities are the basic formulae that are true for all the values of the reference angle.

For the given situation,

The derivation for the tangent sum identity is given in the table below.

The derivation follows the steps,

[tex]\frac{sin(x+y)}{cos(x+y)}[/tex]

we know that, [tex]sin(x+y) = sinx cosy + cosx siny[/tex] ,

[tex]cos(x+y)=cosxcoxy - sinxsiny[/tex] and

[tex]\frac{sinx}{cosx}=tanx[/tex]

⇒ [tex]\frac{sinxcosy + cosxsiny}{cosxcosy-sinxsiny}[/tex]

Divide each term by [tex]cosxcosy[/tex]

⇒ [tex]\frac{\frac{sinxcosy}{cosxcosy} +\frac{cosxsiny }{cosxcosy} }{\frac{cosxcosy}{cosxcosy} -\frac{sinxsiny}{cosxcosy} }[/tex]

⇒ [tex]\frac{tanx+tany}{1-tanxtany}[/tex]

Hence we can conclude that the derivation of tangent sum identity is option I --> IV --> II --> III.

Answer:

3/2 cups of flour

1/4 cups of butter

Step-by-step explanation:

Cups of flour = 6

Cups of sugar = 2

Cup of butter = 1

Marcos only has ½ cup of sugar, so he's going to make a smaller cake.

Cups of sugar for big cake = 2

Cups of sugar for small cake = 1/2

Ratio of cups of sugar for big cake to small cake is

= 2 : 1/2

= 2 ÷ 1/2

= 2 × 2/1

= 4

This means to make smaller cake, all recipes should be divided by 4

Flour for small cake = flour for big cake / 4

= 6 / 4

= 3/2 cups of flour

= 1.33

Butter for small cake = Butter for big cake / 4

= 1 / 4 cups of butter

= 0.25

Answer:

The constant of variation is k=5

Step-by-step explanation:

Proportions

A direct proportion is a relation between variables where their ratio is a constant value. This means that if y and x are proportional, then:

[tex]y=k\cdot x[/tex]

Where k is the constant of proportionality.

We know R varies directly with S. Their relationship is:

[tex]R=k\cdot S[/tex]

We also have when S=16, R=80. Thus:

[tex]80=k\cdot 16[/tex]

Solving for k:

[tex]k=80/16=5[/tex]

The constant of variation is k=5

Its Not The Answer But Its Your Question Simplified

Answer:

I don't know if this is correct but it probably is but I got x=5

Step-by-step explanation:

you write the equation and put the line through the sign, and cross out the 3. Then you are going to add 3 to the seven which will then equal 2x > 10. Then you cross out the 2 and divide both side with the 2. and 10 divided by 2 is 5 so therefore x equals 5.

Answer:

the first choice, the second choice, and the last choice

Step-by-step explanation:

5 and 6 because they are alternate angles
