Answer:

Blank 1: 2

Blank 2: 3

Blank 3: square'

Blank 4: seven cubed

Step-by-step explanation:

For something to be considered a radical expression, it should be written as follows:

\sqrt[m]{x^{n} }

<em>Where:</em>

<em>m=Index of the radical,</em>

<em>n=exponent of the radical</em>

In this case:

7^{\frac{3}{2} } =\sqrt[2]{7^{3} }

Thus;

The index is 2, the exponent is 3, and the expression can be read as the square root of seven cubed.

Answer:

Step-by-step explanation:

That'd be the second root of 7^3, where 3 is the exponent of the radical.

Solve, using linear combination.
Bingel [31]

Multiply the first equation by -1 to get  -4x - y = --5

Then add the second equation               3x + y = 3    

                                                           + ____________  

                                                                  -x = -2  or x = 2


then plug in 2 for x in one of the equations and solve for y      4(2) + y = 5  

                                                                                                          8 + y = 5

                           Subtract 8 from both sides                                        y = -3


                             So x = 2, y = -3     or (2,-3)

10a. The y-intercept of the estimated line of best fit is at (0,b). Enter the approximate value of b. Round your estimate to the
vredina [299]

Answer:

The answer is below

Step-by-step explanation:

The equation of a straight line is given as:

y = mx + b; where m is the slope of the line and b is the y intercept (that is value of y at x = 0).

a) From the graph, we can see that the straight line touches the y axis at $100 in which the temperature is 0 degrees. Therefore the y intercept is:

(0, 100)

b) The slope of the line can be gotten by taking two points that the line passes through. Using the points (0, 100) and (12, 500):

slope(m)=\frac{y_2-y_1}{x_2-x_1} =\frac{500-100}{12-0} =33.3

Find the area of the figure.
seraphim [82]

\huge \bf༆ Answer ༄

At first Divide the figure into two rectangles, I and Il

Area of figure l is ~

  • \sf24 \times (40 - 30)

  • \sf24 \times 10

  • \sf240 \:  \: ft {}^{2}

Area of figure ll is ~

  • \sf 18 \times 30

  • \sf540 \: ft{}^{2}

Area of whole figure = Area ( l + ll )

that is equal to ~

  • \sf240 + 540

  • \sf780 \:  \: ft{}^{2}
