Answer:
Options (C) and (E).
Step-by-step explanation:
Rotation is a rigid transformation in which size and shape of the figure and image remains the same.
That means angles and sides of the triangles given in the figure will remain same after the transformations given.
Since, the given triangle has been rotated about a point Z, each rotation will share the vertex Z.
And every figure is the transformed form of the given triangle, all four triangles will be congruent.
Options (C) and (E) are the correct options.
Answer:
14981yd^2
Step by step:
1) surface area formula: SA=2bs+b^2
s=height
b=square of base
so
SA=2*71*70+71^2
SA=2*71*70+5041
SA=9940+5041
SA=14981
Answer: 405
Step-by-step explanation:
ratio r for the geometric sequence: 5, 15, 45, 135
r is a radios of a circle,
d is the Diameter
r1=5. r2=15, r3=45, r4=135, r5=?
2*r=d
so:
d1=10, d2=30, d3=90, d4= 270
now following the sequence:
r1+d1=r2 5+10=15
r2+d2=r3 15+30=45
r3+d3=r4 45+90=135
r4+d4=r5 therefore 135 + (135*2) = 135+270=405
Answer:
The constant of porportionality is k = 12.5; the equation that describes the relationship is y = 12.5x.
Step-by-step explanation:
When you divide the miles by the hours, it's always 12.5, meaning that k must be 12.5.
If x is the hours and k is 12.5, the equation that describes the relationship is y = 12.5x.
