help a sista out lol.... but plz help!!

A local pizza place has a special deal on Thursday: Buy a large one topping pizza for $12 and each order of cheesy bread is $2.50. This creates a linear equation that represents the cost of the purchase of multiple orders of cheesy bread. What would be the rate of change in this word problem?

A. 2.5
B. 1/ 2.5
C. 4.8
D. 1/4.8

Answer:

y=-5/2x-8

Step-by-step explanation:

Please mark as brainliest if correct

Answer:

Step-by-step explanation:

Let x = base side length

y = side height

volume V = x²y

y = V/x²

surface area

A = x² + 4xy

A = x² + 4x(V/x²)

A = x² + 4V/x

Solving for volume

V = (A - x²)(x/4)

V = ¼(Ax - x³)

a maximum will occur when the derivative equals zero

V' = ¼(A - 3x²)

0 = ¼(A - 3x²)

0 = A - 3x²

3x² = A

3x² = 1100

x² = (1100 / 3)

x = √(1100/3)

V = (A - x²)(x/4)

V = (1100 - √(1100/3))²(√(1100/3)/4)

V = 3,510.56606...

V = 3510.6 cm³

The box height will be half of the base side length.

y = ½√(1100/3)

Step-by-step explanation:

13 is less than 15

Substitute sin(x) = tan(t) and cos(x) dx = sec²(t) dt. We want this change of variable to be reversible, so let's assume bot x and t are bounded between 0 and π/2.

Then we have

[tex]\displaystyle \int \frac{\cos(x)}{\sqrt{1 + \sin^2(x)}} \, dx = \int \frac{\sec^2(t)}{\sqrt{1 + \tan^2(t)}} \, dt[/tex]

Recall the Pythagorean identity,

1 + tan²(t) = sec²(t)

Then

√(1 + tan²(t)) = √(sec²(t)) = sec(t)

and the integral reduces to

[tex]\displaystyle \int \frac{\sec^2(t)}{\sqrt{1 + \tan^2(t)}} \, dt = \int \frac{\sec^2(t)}{\sec(t)} \, dt = \int \sec(t) \, dt = \ln|\sec(t)+\tan(t)| + C[/tex]

Change the variable back to x, so the antiderivative is

[tex]\displaystyle \int \frac{\cos(x)}{\sqrt{1 + \sin^2(x)}} \, dx = \ln \left|\sec\left(\tan^{-1}(\sin(x))\right) + \tan\left(\tan^{-1}(\sin(x))\right) \right| + C [/tex]

[tex]\displaystyle \int \frac{\cos(x)}{\sqrt{1 + \sin^2(x)}} \, dx = \boxed{\ln \left|\sqrt{1+\sin^2(x)} + \sin(x) \right| + C} [/tex]

Answer:

4.5

Step-by-step explanation:

∛100 = ?

100 = 2 x 2 x 5 x 5

∛100

= ∛ ( 2 x 2 x 5 x 5 )

= 4.642

4.642 ~ 4.5

The approximation 4.642 can also be written as 4.5

Therefore,

∛100 = 4.5

Hi how u doin ?

[tex] \frac{16}{x + 4} = \frac{1}{2} \\ [/tex]

inverse both sides

[tex] \frac{x + 4}{16} = \frac{2}{1} \\ [/tex]

Multiply both sides by 16

[tex]16 \times \frac{x + 4}{16} = 16 \times 2 \\ [/tex]

[tex]x + 4 = 32[/tex]

Subtract both sides 4

[tex]x + 4 - 4 = 32 - 4[/tex]

[tex]x = 28[/tex]

There u go..... Have a great day ❤

keeping in mind that the midsegment of a triangle is half the length of the parallel base/side, Check the picture below.

Answer:

  336 cm³

Step-by-step explanation:

As long as the height is measured perpendicular to the base, the volume formula applies.

  V = LWH

  V = (8 cm)(6 cm)(7 cm) = 336 cm³ . . . . volume of the prism

[tex]\large{\rm{\underline{\underline{Answer:}}}}[/tex]

In Direct formula method:

If the rate of appreciation r, the initial value I, the final value V, and the period of appreciation n, the formula for appreciation is given by:

V = I(1 + r)ⁿ

In our case, we need to work out the value of n which is number of years in between 2010 and 2012.

So, n = 2012 - 2010 = 2 years

Put the values we have:

⇛180000 = I(1.20)² [ Increases 20% every year ]

⇛180000 = 1.44I

⇛I = 180000/1.44

⇛I = 125000

So, in 2010, the value of the vase was $125000

Answer: 0.31

Step-by-step explanation: I did some math (5.19 / 16.8 = 3.089 rounded up is 0.31

Step-by-step explanation:

Here Given,

x = White rectangular box

-x = Black rectangular box

1 = White square

-1 = Black square

Condition,

No. of White rectangular boxes = 5

No. of Black rectangular boxes = 8

No. of White square boxes = 9

No. of Black square boxes = 4

Therefore Simplification,

5x + (-8x) + 9 + (-4)

= - 3x + 5 (Ans) (option D)

Here Given,

x = White rectangular box

-x = Black rectangular box

1 = White square

-1 = Black square

Condition,

Left side,

No. of White rectangular boxes = 7

No. of Black rectangular boxes = 3

No. of White square boxes = 1

No. of Black square boxes = 2

Right side,

No. of White rectangular boxes = 1

No. of Black rectangular boxes = 3

No. of White square boxes = 8

No. of Black square boxes = 3

Therefore Equation,

7x - 3x + 1 - 2 = x - 3x + 8 - 3

=> 6x = 6

=> x = 1 (Ans) (option B)

Given values,

a = 13, b = 3, c = 6

Solution,

[tex](26 - a) + \frac{ - 2bc}{2} + \sqrt{289} [/tex]

(On putting values of a, b and c)

[tex] = (26 - 13) + \frac{ - 2 \times 3 \times 6}{2} + \sqrt{289} [/tex]

= 13 + (-18) + 17

= 12 (Ans) (option A)

Given values,

x = 14, y = 5, z = 6

Solution,

[tex] (25 - x) + \frac{4yz}{2} [/tex]

(On putting values of x, y and z)

[tex] = (25 - 14) + \frac{4 \times 5 \times 6}{2} [/tex]

= 11 + 60

= 71 (Ans)

Answer:

  y +17 = -5/3(x -19)

Step-by-step explanation:

The point-slope form of the equation for a line is ...

  y -k = m(x -h) . . . . . . . line with slope m through point (h, k)

You want a line with slope -5/3 through point (19, -17). Its equation is ...

  y -(-17) = -5/3(x -19) . . . . . substitute the given values

  y +17 = -5/3(x -19) . . . . . simplify

Answer:

Part A: 1 solution

Part B:

3(2x-7)=3

6x-21=3

 +21  +21

6x=24

/6    /6

x=4

Step-by-step explanation:

First you distribute 3(2x-7)=3 to 6x-21=3. Next you do inverse operations by adding 21 to both sides of the equation to get 6x=24. Finally you divide both sides by 6 to get x=4

Answer:

185.64 [tex]cm^{2}[/tex]

Step-by-step explanation:

Width =7.5+3.9*2 = 15.3 cm

Length = 8.5+3.9*2=16.3 cm

Big Area = 15.3*16.3 = 249.39 [tex]cm^{2}[/tex]

Small Area = 7.5*8.5 = 63.75 1 [tex]cm^{2}[/tex]

area bounded by the path of the bug = 249.39-63.75 = 185.64 [tex]cm^{2}[/tex]
