Find the area of a parallelogram if a base and corresponding altitude have the indicated lengths. Write your answer as a mixed n

seraphim [82]

There are several information's already given in the question. Based on the given information's the answer can be easily deduced.

Base of the parallelogram = 3 1/2 feet
= 7/2 feet

Altitude of the parallelogram = 3/4 feet

Area of the parallelogram = base * Altitude
= (7/2) * (3/4)
= 21/8
= 2 5/8 square feet

Graph the image of the given triangle under a dilation with a scale factor of −2 and center of dilation (0, 0) .

Ronch [10]

To dilate an object means to enlarge or reduce the size of the object. The scale factor will determine how much larger or smaller the object will become. If this factor is greater than 1, the object will increase in size. Otherwise, if the factor is less than 1, the object will decrease in size. So, the dilated object will be similar to its original. On the other hand, when corresponding points of the original and dilated figures are connected by straight lines, the center of dilation is the point where all the lines meet. In this problem, the center is (0, 0). When the center is the origin we need to multiply all the original coordinates of the object by the scale factor given. So:

$A(-4, 1) \rightarrow A'=-2(-4,1) \rightarrow A'(8,-2) \\ \\ B(-3, -4) \rightarrow B'=-2(-3,-4) \rightarrow B'(6,8) \\ \\ C(-2, -2) \rightarrow C'=-2(-2,-2) \rightarrow C'(4,4)$

So, the graph of the dilated triangle is shown in the Figure below

9514 1404 393

Answer:

y = x^2 +10x -9

Step-by-step explanation:

Quadratic regression generally requires the use of "technology" to aid in finding the equation of the curve of best fit. Use the technology you've been introduced to.

When only a few data points are provided, I prefer to use the Desmos graphing calculator. It shows the equation to be ...
