The given curve is → x²=y, which is a parabola opening upwards and vertex at (0,0).
When it is reflected in x axis ,the curve becomes→ x²=-y
The graph of two curves are shown.
Now the curve ,x²= -y is scaled vertically by a factor of 1/8.
So, the equation of curve becomes ,→ x²= -y × 1/8
→ x² = -y/8
Plotting the graph of →x² = -y/8
The curve will shrink, as scaling is less than 1.

Answer:
65°
Step-by-step explanation:
Short arc AC is the difference between 360° and long arc ABC:
arc AC = 360° -230° = 130°
The inscribed angle ABC that intercepts this short arc will have half the measure of the arc:
∠ABC = 130°/2 = 65°
Answer:
Total number of orange trees = 77 trees
Step-by-step explanation:
Given:
Total number of rows = 15
Total number of cherry rows = 4
Number of trees in each rows = 7
Find:
Total number of orange trees
Computation:
Total number of orange trees = [Total number of rows - Total number of cherry rows][Number of trees in each rows]
Total number of orange trees = [15 - 4]7
Total number of orange trees = [11]7
Total number of orange trees = 77 trees
