The table below shows the temperature, in Fahrenheit, that was recorded
every hour from 9:00 P.M. to 8:00 A.M. at Dulles International Airport.
Assuming a quadratic relationship, if time = 0 represents 9:00 P.M., which
would the model predict the temperature to be at 11:00 A.M., to the nearest

What is a quadratic equation?

A quadratic equation is a second-order polynomial equation in a single variable, x.

To write a quadratic relationship, consider the first three points: let it be A (0,70), B (1,69.7), and C (2,69.1).

To find the constant value, we substitute the first point in the quadratic function.

i.e   [tex]y=ax^{2} +bx+c[/tex]

At point A,  the equation becomes

y=0+0+c=70

i.e c=70

At point B, the equation becomes

a+b=69.7

At point C, the equation becomes

4a+2b=69.1

By solving the two equations above, we get the values of a and b.

a=-35.15 and b=104.85

Then the quadratic relationship becomes

[tex]y=-35.15x^{2} +104.85x+70[/tex]

At 11:00 A.M, the temperature becomes

y(10°) =-35.15(14*14) + 104.85(14)+70

y(10°)=-5351.5

The predicted temperature at 11.00 A.M is given by,  y(10°)=-5351.5

Use the Distributive Property to write 2(−5 + 3) as an equivalent expression. What is the value of the expression? MARKING BRAINLIST

Answers

Answer:

-10+6=-4

Step-by-step explanation:

Here's why we use distributive property, so a(b+c) = ab+ac, therefore 2(-5+3) is -10+6, which is equal to -4.

Answer:

I don't know what you mean, but I will try to answer.

2(-5+3)= -10+6

Value: -4

Step-by-step explanation:

2(-5+3)=

First, "distribute" the two by multiplying it to each of the two numbers in the parenthesis.

2(-5)= -10

2(3)= 6

After you finished multiplying, you will have this:

-10 + 6= (I am pretty sure this is equivalent to what you started with)

Now, you get the answer for the equation.  You would add -10 and 6 to get -4.

the total bill was $58 so we have to subtract the $40 monthly bill part to find how much extra money she paid because her call was over 200 minutes

58-40=18

Then divide the $18 by $0.15 since the $18 is the total amount of each time she was charged $0.15 for going 1 minute over 200 minutes

18÷0.15 = 120

120 is te Amount Of minutes she went over her 200 minute limit

The cost of 11.5 sheets of stickers costs is $40.25.

What is the unitary method?

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Given that, four sheets of stickers cost $14.

Now, the cost of 1 sheet of stickers is 14/4

= $3.5

The cost of [tex]11\frac{1}{2}[/tex] =11.5 sheet of stickers is

11.5×3.5

= $40.25

Therefore, the cost of 11.5 sheets of stickers costs is $40.25.

Multiplication Property of Equality Division Property of Equality Addition Property of Equality Subtract Property of Equality

Step-by-step explanation:

Step 1: Define

20(x + 9) = 140

Step 2: Solve for x

Divide 20 on both sides:                    x + 9 = 7Subtract 9 on both sides:                   x = -2

Step 3: Check

Plug in x into the original equation to verify it's a solution.

Substitute in x:                    20(-2 + 9) = 140(Parenthesis) Add:              20(7) = 140Multiply:                               140 = 140

Here we see that 140 does indeed equal 140.

∴ x = -2 is the solution to the equation.

Answers

Using translation concepts, it is found that the equation is given by:

[tex]y = -3\sqrt[3]{x} - 8[/tex]

What is a translation?

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.

The parent cube root function is given by:

[tex]y = \sqrt[3]{x}[/tex]

It was reflected across the x-axis, that is, multiplied by -1, hence:

[tex]y = -\sqrt[3]{x}[/tex]

It was vertically stretched by a factor of 3, hence:

[tex]y = -3\sqrt[3]{x}[/tex]

Then, it was translated 8 units down, hence:

Kathy needs money for a trip to Europe if she has US$300 in the bank but wants to withdraw half of it In British pounds and half of it into euros how many more euros and times with Havasu 1 pound equals 1.6 for US deep and one euro equals 1.3 to USD and round to the nearest whole

Answers

Answer: She has 21.63 more euros than pounds and has 1.23 times more euros than pounds.

Step-by-step explanation:

She has US$300, and she will withdraw half of it on pounds, and half of it in euros.

(half of US$300 is US$150)

We know that:

1 pound = US$1.6

(1 pound/US$1.6) = 1

Then US$150 = US$150*(1 pound/US$1.6) = (150/1.6) pounds = 93.75 pounds.

And we also know that:

1 euro = US$ 1.3

then:

(1 euro/US$ 1.3) = 1

This means that:

US$150 = US$150*(1 euro/US$ 1.3) = (150/1.3) euros = 115.38 euros.

This means that:

115.38 - 93.75 = 21.63

This means that she has 21.63 more euros than pounds.

and:

115.38/93.75 = 1.23

She has 1.23 times more euros than pounds.

which statement and reason best complete the proof

Answers

Answer:

Segment EG ≅ segment EG by the reflexive property.

Step-by-step explanation:

In the diagram given, already, two angles (<H and <HEG) of ∆HEG has been stated to be equal to two corresponding angles (<F and <FGE) of ∆FGE.

To prove that ∆HEG is congruent to ∆HEG by the Angle-Angle-Side Congruence Theorem, we need to state that they also have one corresponding side that is congruent.

Therefore, the statement and reason that will complete the proof would be:

Segment EG is congruent to segment EG by the reflexive property.

Both triangles share the same segment, EG. This completes the proof.

Remark

A_n = 3*2^(n - 1) I will assume that's what you mean. I'll give the answer for A_n = 3*2^n - 1 as well.

Solution

n = 8

A_n = 3 *2^(8 - 1)

A_8 = 3*2^7

A_8 = 3* 128

A_8 = 384

If you mean A_n = 3*2^n - 1

Then you would get

A_n =3 * 2^8 - 1

A_8 = 3 * 256 - 1

A_8 = 768 - 1

A_8 = 767

h = 24 cm

and the circumference of the cylinder, C = 33 cm

[tex]2\pi r=33\\\\r=\dfrac{33}{2\pi}\\\\r=5.25\ cm[/tex]

We need to find the volume of the cylinder so formed. The formula for the cylinder is given by :
