Step-by-step explanation:
Answer:
2^5 and 3^4
Step-by-step explanation:
you can see there are 5 2's and 4 3's. so it would be 2^5 and 3^4
Answer:
13.6%
Step-by-step explanation:
Step 1
Find the actual volume of the box
Volume = Length × Width × Height
You measure the box and find that it has a length of 10 inches, a width of 9 inches, and a helght of 4.5 inches.
Volume = 10 inches × 9 inches × 4.5 inches
Volume of the box = 405 cubic inches
Step 2
Calculate the percent error
|Estimated value - Actual value|/Actual value ×100
Estimated value= 350 cubic inches
Actual value = 405 cubic inches
= |350 - 405|/405 × 100
= |-55|/405 × 100
= 55/405 × 100
= 13.580246914%
Approximately = 13.6%
The Percent error is 13.6%
Answer:
The set of transformations has been performed on triangle ABC is dilation by a scale factor of 2 followed by reflection about the x-axis
Step-by-step explanation:
Let us write the vertices of Δ ABC
∵ Vertex A = (-2, -1)
∵ Vertex B = (0, 0)
∵ Vertex C = (1, -3)
Let us Write the vertices of Δ A'B'C'
∵ Vertex A' = (-4, 2)
∵ Vertex B' = (0, 0)
∵ Vertex C' = (2, 6)
Let us find the scale factor k between the x-coordinates of the points and their images.
∵ -4 = k (-2) ⇒ Divide both side by -2
∵ =
∴ 2 = k
∴ The scale factor of a dilation is 2
∵ The signs of the y-coordinates of the images are the opposite of
the signs of the y-coordinates of the points
∴ The triangle is reflected about the x-axis
∴ The set of transformations has been performed on triangle ABC
is dilation by a scale factor of 2 followed by reflection about the x-axis
