Answer:
Any of ...
- rotation 180° about the center of symmetry
- reflection across the horizontal and vertical lines through the center of symmetry, in either order
- reflection across any horizontal line, translation to the left, and translation up or down to final position (depending on where the horizontal line is)
Step-by-step explanation:
The question is asking you what combinations of rotation, reflection, translation, and dilation will make the W have the position, orientation, and size of the M.
The image (M) is the same size as the preimage (W), so no dilation is involved.
The up-down orientation of the image is opposite that of the preimage, so reflection across a horizontal line, or rotation 180° will be involved. Depending on the line of reflection or the center of rotation, translation to the final image position may be required.
The preimage is symmetrical about a vertical centerline, so translation left or right can also be accomplished by reflection about a suitable vertical line.
_____
If you have trouble visualizing this, it can help to cut the letter from a piece of paper and manipulate it to model rotation, reflection, or translation.
Option 4 - 707
Step-by-step explanation:
Step 1:
Given that the spray from a sprinkler creates a circle with a radius of 15 feet.
We need to determine how many square feet of grass the sprinkler covers. To find this we need to find the circle's area that the sprinkler covers.
Hence we need to determine the circle's area having radius 15 feet
Step 2 :
We have the area of circle having radius r as pi * r ^2
So when r = 15, the area is
(22/7) * 15* 15 (where pi = 22/7)
= 707.14
Hence the area which is covered with the spray from the sprinkler is approximately 707 feet.
Option 4 is the answer
Answer:
6 the piju dunno fine I've into
Answer:
Step-by-step explanation:
We can use the quadratic formula or factor, This looks hard to factor so we should use the quadratic formula.
ax^2 + bx + c
so
a=4
b=-9
c=2
you can try it by hand or use this:
https://www.calculatorsoup.com/calculators/algebra/quadratic-formula-calculator.php
you get x=2 and x=0.25 these are the x intercepts (where Y is zero and where the graph crosses the x axis)
so mark x=2 and x=0.25 with a dot on a number line and you can draw a straight line between them since that is the part of the graph that is below the x axis (because the equation has <0) it is a positive parabola because the "a" value is positive and the presence of a "b" value means part of the graph will be below the x axis
