Step-by-step explanation:

Answer:

-2

Step-by-step explanation:

The formula for finding the slope is y2-y1 divided by x2-x1. You can use any two points.

So,

220-240 divided by 10-0= -20/10= -2

Answer:

Only Ingrid's equation is correct

Answer:

Only Ingrid’s solution works

Answer:

this is a Sin(), Cos() and Tan()  function  problem.   use the Mnemonic  (new-monic)  SOH CAH TOA  (soo caw tow ah ) to remember which function  sin() cos()  or tan() to use.. :) these types of problems are pretty confusing, Use that Mnemonic to keep the functions in order

Step-by-step explanation:

since we know the distance to the tree.. and we know the angle and we have a formula  TOA to figure out the one pieces of info we don't know ...  use TOA  that tells us our formula..  TOA(Ф)=Opp /  Adj     where  Tan(Ф) is using Ф= to our angle of 32 degrees ( remember Ф can be in degrees or radians, its in degrees for this problem) Adj = the Adjacent side of the triangle from the known angle.. the 32 degree angle ,  Opp = the Opposite side of the triangle formed by the imaginary lines from Kari to the base of the tree and from Kari to the top of the tree..   and then the tree , from it's base to it's top... we know the angle and the Adj side of that triangle so we can figure out that last part of TOA  by saying  Tan(Ф)=Opp/ Adj .... or say  Tan(32)= Opp / Adj    ⇒ Tan(32)=Opp / 90 ⇒ Tan(32) *90 = Opp   this will be the height from the ground to the top of the tree..  but.. the tree is at an angle , keep in mind... sooo  Tan(32)*90=56.238 feet  now take the new triangle that we know one side to... from the ground to the height of the tree..  in a vertical line from the ground to a point at 56.238 feet .. that is the Adj side of this new triangle.. the tree is on the Hypotenuse of this new trialge,  which we want to find. we know the Adj side we know the angle to find the Hypotenuse use CAH , from our Mnemonic at the top,  the Mnemonic is really important b/c keeping track of which part goes where in the triangles is pretty confusing.  Cos(5)=Adj / Hyp  ⇒ Cos(5)=56.238 / Hyp ⇒56.238 / Cos(5)= Hyp   = 56.453 feet  :)  that's how tall that tree is , lets chop it down :P and blame it on George Washington  :P  The tree, to the nearest 10th of a foot, is 56.5 feet

Answer:

The solution is [tex]\displaystyle x=1\pm \sqrt{47}[/tex]. Fourth option

Explanation:

Solve for x:

[tex]2x^2+3x-7=x^2+5x+39[/tex]

Move all the terms from the right to the left side of the equation, a zero in the right side:

[tex]2x^2+3x-7-x^2-5x-39=0[/tex]

Join all like terms:

[tex]x^2-2x-46=0[/tex]

The general form of the quadratic equation is:

[tex]ax^2+bx+c=0[/tex]

Solve the quadratic equation by using the formula:

[tex]\displaystyle x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]

In our equation: a=1, b=-2, c=-46

Substituting into the formula:

[tex]\displaystyle x=\frac{-(-2)\pm \sqrt{(-2)^2-4(1)(-46)}}{2(1)}[/tex]

[tex]\displaystyle x=\frac{2\pm \sqrt{4+184}}{2}[/tex]

[tex]\displaystyle x=\frac{2\pm \sqrt{188}}{2}[/tex]

Since 188=4*47

[tex]\displaystyle x=\frac{2\pm \sqrt{4*47}}{2}[/tex]

Take the square root of 4:

[tex]\displaystyle x=\frac{2\pm 2\sqrt{47}}{2}[/tex]

Divide by 2:

[tex]\displaystyle x=1\pm \sqrt{47}[/tex]

First option: Incorrect. The answer does not match

Second option: Incorrect. The answer does not match

Third option: Incorrect. The answer does not match

Fourth option: Correct. The answer matches exactly this option

Answer:

y = x - 3

if you plug in the numbers from the table, it checks out.

y = x - 3

0 = 3 - 3

0 = 0

y = x - 3

1 = 4 - 3

1 = 1

y = x - 3

2 = 5 - 3

2 = 2

and so on

Answer:

163

Step-by-step explanation:

10(10)+9(7)=

100+63=163

Answer:

163

Step-by-step explanation:

If z=10 and w=7.

10z+9w [writing the equation again for reference purposes]

10(10) + 9(7) [we substitute each variable with its defined value]

100 + 9(7) [we multiply 10 and 10, aka 10 and z]

100 + 63 [we multiple 9 and 7, aka 9 and w]

163 [we add 100 and 63 to get our final answer]

Step-by-step explanation:

Answer:

(a) [tex]\hat y=69.04-0.083\cdot x[/tex]

(b) D. For every unit increase in commute​ time, the index score falls by 0.083​, on average.

Step-by-step explanation:

(a)

Form the least-squares regression line using Excel as follows:

Go to Data → Data Analysis → Regression

A dialog box will open.

Select the X and Y variable.

Press Ok.

The regression output is attached below.

The least-squares regression line is:

[tex]\hat y=69.04-0.083\cdot x[/tex]

(b)

The slope of a regression line is the average rate of change in the dependent variable (y) with 1 unit change in the independent variable (x).

Here the slope value is -0.083. This value implies that with 1 minute change in the commute times the Well-Being Index​ Score falls by 0.083 units.

The intercept of a regression line is the average value of the dependent variable (y) when the independent variable (x) value is 0.

Here, the intercept value is 69.04. This value implies that for a person with commute time 0, their Well-Being Index​ Score is 69.04.

The correct option is:

D. For every unit increase in commute​ time, the index score falls by 0.083​, on average.

Answer:

Number of seats in first row = 2

Number of seats in 2nd row = 4

Number of seats in 3rd row = 6

Step-by-step explanation:

Let's say number of seats in first row is x.

Now we are told that each row must have two more seats

than the one before it.

Thus, the remaining 2 rows have;

(x + 2) and (x + 4) seats respectively.

We are told that that the front row must have one quarter the total seats in the

back 2 rows combined.

Thus;

x = ¼((x + 2) + (x + 4))

Multiply both sides by 4 to give;

4x = x + 2 + x + 4

4x = 2x + 4

4x - 2x = 4

2x = 4

x = 4/2

x = 2

Thus;

Number of seats in first row = x = 2

Number of seats in 2nd row = (x + 2) = 2 + 2 = 4

Number of seats in 3rd row = (x + 4) = 2 + 4 = 6

Answer:

[tex]y = ab^{x} [/tex]

[tex]y = 3 \times {4}^{x} [/tex]

"a" is the initial amount (3), and "b" is the growth factor (4).

To find "b" plug in the knowns into the exponential function equation and solve.

[tex]y = ab^{x} [/tex]

[tex]48 = 3 \times {b}^{2} [/tex]

[tex]16 = {b}^{2} [/tex]

[tex] \sqrt{16} = b[/tex]

[tex]b = 4[/tex]

Answer:

D, R: {11, -4, -29}

Step-by-step explanation:

According to the given set of domains, the corresponding range is found by substituting the x values into the equation and solving for y.

i.e {-2} -> 5x + y = 1, -10 + y = 1, y = 11

{1} -> 5x + y = 1, 5 + y = 1, y = -4

{6} -> 5x + y = 1, 30 + y = 1, y = -29

Answer:

The short answer is D
