Answer:

The area between the two functions is approximately 1.333 units.

Step-by-step explanation:

If I understand your question correctly, you're looking for the area surrounded by the the line y = 2x and the parabola y = x², (as shown in the attached image).

To do this, we just need to take the integral of y = x², and subtract that from the area under y = 2x, within that range.

First we need to find where they intersect:

2x = x²

2 = x

So they intersect at (2, 4) and (0, 0)

Now we simply need to take the integrals of each, subtracting the parabola from the line (as the parabola will have lower values in that range):

[tex]a = \int\limits^2_0 {2x} \, dx - \int\limits^2_0 {x^2} \, dx\\\\a = x^2\left \{ {{x=2} \atop {x=0}} \right - \frac{x^3}{3}\left \{ {{x=2} \atop {x=0}} \right\\\\a = (2^2 - 0^2) - (\frac{2^3}{3} - \frac{0^3}{3})\\\\a = 2^2 - \frac{2^3}{3}\\a = 4 - 8/3\\a \approx 1.333[/tex]

So the correct answer is C, the area between the two functions is 4/3 units.

The area between the two functions is approximately 1.333 units.

Area is defined as the region bounded by the sides on a plane. The areas of different shapes can be calculated by different formulas.

[tex]a=\int\limits^2_0 {2x} \, dx -\int\limits^2_0 {x^2} \, dx[/tex]

[tex]a=(2^2-0^2)-(\dfrac{2^3}{3}-\dfrac{0^3}{3})[/tex]

[tex]a=4-\dfrac{8}{3}[/tex]

[tex]a=1.333[/tex]

Hence the area between the two functions is approximately 1.333 units.

Answer:

One serving of oatmeal provides 4.6% of the daily recommended allowance of fat.

Step-by-step explanation:

3/65 ≅ 0.046 = 4.6%

One serving of oatmeal provides 4.6% of the daily recommended allowance of fat.

The question is incomplete. Here is the complete question.

Part A

The value of a collectible toy is increasing exponentially. The two points on the graph show the toy's initial value and its value 3 weeks afterward.

Express the toy's value t, in dollars, as a function of time w in weeks after purchase.

Part B

Write an expression to represent the toy's value 10 days after purchase

Answer and Step-by-step explanation: An exponential function is of the form: [tex]y=ab^{x}[/tex]

Part A

Translating to the question, the toy's value as a function of time is

[tex]t=ab^{w}[/tex]

To determine constants a and b, we use points given by graph.

First, (0,5) to find a:

[tex]5=a.b^{0}[/tex]

a = 5

Now, (3,10) to determine b:

[tex]10=5b^{3}[/tex]

[tex]b=\sqrt[3]{2}[/tex]

b = 1.26

The toy's value as a function of time in weeks is [tex]t=5.(1.26)^{w}[/tex]

Part B

Since, the function is in weeks:

1 week = 7 days

w weeks = 10 days

[tex]w = \frac{10}{7}[/tex]

Replacing w:

[tex]t=5.(1.26)^{w}[/tex]

[tex]t=5.(1.26)^{10/7}[/tex]

Expression that represents toy's value after 10 days is [tex]t=5.(1.26)^{10/7}[/tex].

8 x ¾ is the same as adding ¾ + ¾ + ¾ + ¾ + ¾

because, when you are adding 3/4

8 times, you are 3/4 plus itself,

eight times,

so you are doing 3/4*8

So we have -5z-6. So the expression equivalent to 1/4(20z+24) is -5z-6.

Answer:

9(19)+13z=17

171+13z=17

13z=171-17

Z=154/13 is the answer

Step-by-step explanation:

Pls mark me in brain list

Answer:

z = -154/13

Step-by-step explanation:

1.) Add the numbers

9(2+17)+13=17

9(19) = 13z = 17

2.) Multiply the numbers

9 x 19 + 13z = 17

171 + 13z = 17

3.) Rearrange terms

171 + 13z = 17

13z + 171 = 17

4.) Subtract 171 from both sides of the equation

13z + 171 = 17

13z + 171 - 171 = 17 - 171

5.) Simplify

13z = -154

Solution

z = -154/13

Radius 4.5 feet what’s is the tabletop area

The area of the table top is 63.62 square feet.

'In geometry, the area can be defined as the space occupied by a flat shape or the surface of an object.'

According to the given problem,

Radius of the table = 4.5 feet

Since, the table is round,

Area of a circle = [tex]\pi r^{2}[/tex]

                         = π × 4.5 × 4.5

                         = 63.617

Hence, we can conclude, the area of the table-top is 63.62 square feet.

Answer:

540°

Step-by-step explanation:

Consider a regular pentagon. Divide it radially into five congruent, isosceles triangles. Each triangle has a vertex angle of 360°/5 = 72°, and base angles of (180°-72°)/2 = 54° each.

An interior angle of the pentagon is made up of two of those 54° angles, so interior angle = 108°.

Sum of interior angles = 5·108° = 540°
