Can someone pls help, I know this is kind of a lot but I’ve been stuck on this for a while now.
The data in the table can be modeled by a quadratic function. Find the function that would fit the data.



The number of hours Temperature

after midnight

6 58

8 68

10 76

12 82

14 84

16 81

18 75









After completing the regression using this information the value of a is (__), the value of b is (__), and the value of c is (__). The equation for the situation is f(x)= (__). Use the equation to predict the temperature one hour after midnight.

Given:

Total paint used = 7.9 pints

Blue paint is [tex]\dfrac{2}{5}[/tex] of this amount.

The remaining paint is white.

To find:

The amount of white paint.

Solution:

Blue paint is [tex]\dfrac{2}{5}[/tex] of 7.9 pints.

[tex]\text{Blue paint}=7.9\times \dfrac{2}{5}[/tex]

[tex]\text{Blue paint}=3.16[/tex]

Now,

[tex]\text{White paint}=\text{Total paint}-\text{Blue paint}[/tex]

[tex]\text{White paint}=7.9-3.16[/tex]

[tex]\text{White paint}=4.74[/tex]

Therefore, the total white paint used in Celia's bedroom walls is 4.74 pints.

Answer:

In ΔHKJ and ΔHIJ

HK=IJ=√17

HI=KJ=√13

HJ=HJ [Common}

ΔHKJ ≅ ΔHIJ [SSS]

Now consider ΔHKI AND ΔKJI

HK=IJ=√17

HI=KJ=√13

KI=KI [Common]

ΔHKI ≅ ΔKJI [SSS]

Now the converse of Parallelogram diagonal theorem also states that if diagonals of a Quadrilateral divides it into two congruent triangles then it is a parallelogram.

Hence the given Quadrilateral is a Parallelogram.

Answer:

The expression consists of two terms, and each term contains two factors.

Step-by-step explanation:

Given - Complete the statement to describe the expression ab + cd

To find - The expression consists of ....... terms, and each term contains .......factors.

Proof -

The given expression has two terms

Term I - ab

Term II - cd

Now,

Each term contains two factors

In Term I - one factor is a and another factor is b

In Term II - one factor is c and another factor is d

Definition used -

It may be a single number (positive or negative), a single variable ( a letter ), several variables multiplied but never added or subtracted.

A factor can be a number, variable, term, or a longer expression.

Answer:

120

Step-by-step explanation:

TQR = 180 - (35+25) = 120

TQP= 180-120=60

TNP=TQP =60

MNT= 180-60=120

Answer:

Step-by-step explanation:

3(7t - 5) - 2t = 4

3*7t - 3*5 - 2t = 4

21t  - 15   - 2t = 4          {combine like terms}

21t - 2t - 15     = 4

         19t - 15 = 4          {Add  15 to both sides}

            19t    = 4 + 15

            19t     = 19    {Divide both sides by 19}

                   t = 19/19

t = 1

Answer:

  15, 27, 39

  a[n] = a[n-1] +12; a[1] = 15

Step-by-step explanation:

The terms of an arithmetic progression have a common difference.

There are numbers in the given list that have differences of 5, 7, 12. The numbers with differences of 5 have already been listed. Other possible sequences are ...

  13, 20, 27 . . . . common difference of 7

  15, 27, 39 . . . . common difference of 12

The rule for the latter sequence is "each term is 12 more than the last" and the first term is 15.

Answer:

y = 3x + 12

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 3 , then

y = 3x + c ← is the partial equation

To find c substitute (1, 15) into the partial equation

15 = 3 + c ⇒ c = 15 - 3 = 12

y = 3x + 12 ← equation of line AB

Answer: I was made for this question the answer is: w=8

Step-by-step explanation:

First you do: 150-30 since you want to cancel it out.

Then: 120/15=8

The answer:8

Answer:

50.39 degrees

Step-by-step explanation:

Model this situation with a right triangle.  The horizontal leg of this right triangle is 24 ft, whereas the height (top) of the house is 29 ft, which forms the vertical leg.  The ratio of these two measurements is 29/24, which is the tangent of the angle of elevation.  Using a calculator to find the new angle:

tan x = 29/24 = 0.88 radian, or 50.39 degrees  

Answer:

See Explanation

Step-by-step explanation:

Given

[tex]Price = 29.50 + 13.50(p - 2)[/tex]

The question has missing details. However, I will solve on a general term.

A possible question could be to find the cost of purchasing (say 10 bottles).

To do this, we simply substitute 10 for p.

So:

[tex]Price = 29.50 + 13.50(p - 2)[/tex]

[tex]Price = 29.50 + 13.50(10 - 2)[/tex]

[tex]Price = 29.50 + 13.50 * 8[/tex]

[tex]Price = 29.50 + 108[/tex]

[tex]Price = 137.50[/tex]

i.e. $137.50 for 10 pint bottles

Another possible question is to calculate the number of pint bottles that amount to (say $70).

To do this, we simply substitute 70 for Price.

So:

[tex]Price = 29.50 + 13.50(p - 2)[/tex]

[tex]70 = 29.50 + 13.50(p - 2)[/tex]

Collect like terms

[tex]70 - 29.50 = 13.50(p - 2)[/tex]

[tex]40.5= 13.50(p - 2)[/tex]

Divide both sides by 13.50

[tex]3= p - 2[/tex]

Add 2 to both sides

[tex]3 + 2 = p - 2 + 2[/tex]

[tex]5 = p[/tex]

[tex]p = 5[/tex]

i.e. $70 will buy 5 pint bottles

i dont know am sorry will you gogive me

Answer:

For the sugar beet part, there are 12 farms that grow sugar beet only and for the in between or the middle of the venn diagram 40 farms grow both sugar beet and potatoes, and for the one on the bottom left its 100 farms since its the total.

Step-by-step explanation:

1. Subtract 48 with 60 to get the rest of number of farms that grow sugar beet only which is 12.

2. Once we complete the 60 farms that grow only sugar beet or potatoes we add the rest which is 40 from the 100 farms to the middle which are the farms that grow both, potatoes and sugar beet.

3. Finally we add the entire total of all farms and write it down on the bottom left.

Hope this helps!

Answer:

E'(-2, -3), F'(-1, -5), G'(1, -5) and H'(2, -3).

Step-by-step explanation:

Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, translation and dilation.

If a point A(x, y) is translated a units right and b units down, the new location of the point is at A'(x + a, y - b)

The location of the vertices of quadrilateral EFGH is E(-5, -1), F(-4, -3), G(-2, -3) and H(-1, -1). If quadrilateral EFGH is translated 3 units right and 2 units down, the new location would be:

E'(-2, -3), F'(-1, -5), G'(1, -5) and H'(2, -3).
