How do I solve this?

Mathematics

Solution

for this case with the first table we can find the equation of the line using the following formula for the slope:

m_1=\frac{y_2-y_1}{x_2-x_1}=\frac{0-2}{-1-0}=2

And the y intercept would be b=2

Then the equation for the first equation is:

y= 2x +2

the second equation is given by:

y= -2x-2

then the best solution would be:

Function 1 has a positive slope and a positive y-intercept. Function2 has a negative slope and a negative y-intercept

Drag each tile to the correct box
ValentinkaMS [17]

Answer:

Arranging the solutions from the least to the highest;

1.         1.743 x 10⁻²

2.        3.626 x 10⁻²

3.        4.64 x 10⁻²

4.        3.162 x 10²

5.        4.214 x 10³

Step-by-step explanation:

The solutions of the mathematical expression are calculated as follows;

1. \ \ (4.3\times 10^6)(9.8\times 10^{-4}) = (4.3\times 9.8\times 10^{6-4}) = (42.14\times 10^2)= 4.214 \times 10^3

2. \ \ (2.9\times 10^7)(1.6\times 10^{-9}) = (2.9\times 1.6\times 10^{7-9}) = 4.64\times 10^{-2}

3. \ \ \frac{(4.7 \times 10^3)(8.6\times 10^{-7})}{(3.8\times 10^{-4})(6.1 \times 10^2)} = \frac{(4.7\times 8.6\times 10^{3-7})}{(3.8\times 6.1\times 10^{-4+2})} = \frac{4.042 \times 10^{-3}}{2.318\times 10^{-1}} = 1.743\times 10^{-2}

4. \ \ (4.9\times 10^3)(7.4\times 10^{-6}) = (4.9\times 7.4\times 10^{3-6}) = 3.626\times 10^{-2}

5. \ \ \frac{(3.9 \times 10^5)(8.7\times 10^{-3})}{(3.7\times 10^{-5})(2.9 \times 10^8)} = \frac{(3.9\times 8.7\times 10^{5-3})}{(3.7\times 2.9\times 10^{-4 +8 })} = \frac{3.393 \times 10^{-1}}{1.073\times 10^{-3}} = 3.162\times 10^{2}

Arranging the solutions from the least to the highest;

1.         1.743 x 10⁻²

2.        3.626 x 10⁻²

3.        4.64 x 10⁻²

4.        3.162 x 10²

5.        4.214 x 10³

A carpenter needs to cut four sections, each 3–feet 8–inches long, from a piece of molding. If the board is only sold by the foo
KIM [24]

Alright, lets get started.

The length of each section what carpenter needs to cut is 3 feet and 8 inches.

Converting 3 feet and 8 inches into feet only, we know, 12 inches = 1 feet

So, 3 feet 8 inches = 3 +\frac{8}{12} =3 +\frac{2}{3} =\frac{11}{3} feet

It means length of each section = \frac{11}{3} feet

Carpenter needs to cut 4 sections, so length of 4 sections will be = 4*\frac{11}{3}=\frac{44}{3}=14\frac{2}{3} feet

2/3 feet means 8 inches so she needs board 14 feet 8 inches

Board is only sold by the feet only so, she has to puchase 15 feet board.   :   Answer

Hope it will help :)

A player kicks a soccer ball off of the ground. The height of the ball is modeled by the equation h(t)=-\frac34\left(t-4\right)^
Aneli [31]

Answer:

Step-by-step explanation:

We can solve this in either of two approaches:  Mathematically or Graphically.

<u>Mathematically</u>

y=-(3/4)(x-4)^2+12  where y is the height of the ball, and x is the time, in seconds.

We want to know how many seconds for the height to be 0, so y=0.

0 = -(3/4)(x-4)^2+12

-12 = -(3/4)(x-4)^2

12*(4/3) = (x-4)^2

16 = (x-4)^2

x = 8 and 0 (the initial point).]

It will reach the ground in 8 seconds

<u>Graphically</u>

Plot the function and find the time, x, when the graph passes through the x axis (after t = 0).  Attached.
