First blank options:
1. Interpolation
2. Extrapolation

Second blank options:
1. 71
2. 69
3. 68
4. 59

Answers

Answer:

First blank:  2. Extrapolation

Second blank: 2. 69

Step-by-step explanation:

Extrapolation should be used because the point (x, y) is further than the points included in the table, that is, the x-coordinate will be greater than 12 when y = $0

Replacing y = 0 into the equation, we get:

0 = -115.9x + 8,007.30

115.9x = 8,007.30

x = 8,007.30/115.9

x = 69

Do 0.3 and 3.0 have the same value ? explain

Answers

No, silly.
3.0 is ten times the size of 0.3 .

Take your calculator, and divide one of them by the other one.
If they have the same value, then the answer will be ' 1 '.

Take your calculator and subtract one from the other.
If they have the same value, then the answer will be zero.
No because .3 is 30 cent and 3.0 is 3 dollars.

Hey there, 2(5j+1+6j)=(2)(5j+1+6j)=(2)(5j)+(2)(1)+(2)(6j)=10j+2+12j=22j+12. Therefore, the two expressions are 10j+2+12j and 22j+2.

Solve by using the quadratic formula.
3psquared+7p+2=0

Answers

Answer:

-1/3,-2

Step-by-step explanation:

The quadratic formula is [-b±√(b^2-4ac)]/2a.  In this equations 3p^2 is a, 7p is b, and 2 is c.

Then just plug in the numbers.

[-7±√((-7^2)-4(3)(2)]/2(3)

[-7±√(25)]/6

(-7+5)/6  and  (-7-5)/6

-1/3 and -2 are the answers, if you plug these numbers into the original equation, you find that they equal 0 which means that they work.

Answer:

\large\boxed{x=-2\ or\ x=-(1)/(3)}

Step-by-step explanation:

The quadratic formula of a quadratic equation

ax^2+bx+c=0\n\nx=(-b\pm√(b^2-4ac))/(2a)

We have the equation:

3p^2+7p+2=0\to a=3,\ b=7,\ c=2

Substitute:

b^2-4ac=7^2-4(3)(2)=49-24=25\n\n√(b^2-4ac)=√(25)=5\n\nx_1=(-7-5)/(2(3))=(-12)/(6)=-2\n\nx_2=(-7+5)/(2(3))=(-2)/(6)=-(1)/(3)
