Answer:
rotation 90° CW about the origin we defined
Step-by-step explanation:
The image has the same orientation (clockwise order of vertices) as the pre-image, so an even number of reflections is involved. These cannot be reflections across the x- or y-axes. The longest edge has an east-west orientation in the pre-image and a south-north orientation in the image. Any reflections must have a net effect of a rotation 90° CW.
Equivalently, the image is rotated 90° clockwise from the pre-image.
With a suitable choice of center of rotation, the image can be obtained with a single 90° CW rotation transformation.
If we define the lower left corner of the pre-image as having coordinates (-1, 2), then a 90° CW rotation about (0, 0) will yield the image.
Answer:
184
Step-by-step explanation:
6m + 10p

Answer:
150 miles
Step-by-step explanation:
speed = 120 km per hour
1 mile = 1.6 km
speed = 120 km per hr
divide 120 with 1.6 to get in miles=120/1.6
= 75 miles per hour
speed = 75 miles per hour
So, in 1 hr, it can travel 75 miles
the distance traveled by car in 2 hours = 75 * 2 = 150
Result : Speed = 75 miles per hour , distance = 150 miles
Answer:
Max height: 64 feet, and the socond one was higher.
Step-by-step explanation:
The max height is the y value of the vertex, because that’s when the graph peaks.
we can already very clearly see the vertex on the graph, so we don’t need to calculate it.
the max height of the second golf ball is 64 feet.
Now let’s look at the max height on the first golf ball.
we get the equation
h=-16t squared + 48t
to find the vertex of this, we can use the formula -b/2a
-48/-32 = 1.5
1.5 is the t value of this vertex.
to find the h value, we plug it in.
h = -16 (1.5) squared + 48(1.5)
h =2.25 times -16 + 72
h = -36 +72
h = 36
the first one is 36 max height, and the second is 64. The second one is bigger.
