Answer:
Not a function, because there are more than one of the same x-intercept which makes a vertical line.

Answer:
The area of the shape after it has been enlarged by
scale factor 2 will be: 10 cm²
Step-by-step explanation:
The Area is basically a measure of how much space in square units there is inside an object.
As the shape is shown on the centimeter grid.
- The shape clearly occupies the space of 5-centimeter squares.
We also know that If the scale factor > 1, the image is enlarged.
As we know to determine the area of the shape after it has been enlarged by scale factor 2, all we need to do is to multiply the area of the original shape by 2.
The area of original shape = 5 cm²
The area of the shape after the dilation by a scale factor 2 = 5 × 2 = 10 cm²
Thus, the area of the shape after it has been enlarged by
scale factor 2 will be: 10 cm²
Answer:
base = 2 m; height = 6 m
Step-by-step explanation:
I think your question is missed of key information, allow me to add in and hope it will fit the original one.
Please have a look at the attached photo.
My answer:
Given the information:
- base of 8 meters
- height of 6 meters
- top side length of 4 meters.
=> the height of one of the triangles equal to the the height of the trapezoid = 6 meters
=> the base of the triangles:
= (the base of the trapezoid - the top side length) / 2
= (8-4)/2
= 2
So the base and height of one of the triangles : base = 2 m; height = 6 m
Hope it will find you well.
Answer:
25h-35=440
440+35=25h
475=25h
475÷25=h
h=19
