-4= Contraction
2.5=Expansion
2/3= Contraction
-3/4= Contraction
Best way to solve this, if the scale factor is less than one, is a contraction. If it is greater than one, than it is an expansion.
V=2πrh
28.27=(2)(3.14)(1.5)h
h=28.27/(2)(3.14)(1.5)
h≈3
answer c. 3.0
Answer:
1 and 2 are not congruent; 1 and 3 are congruent; 1 and 4 are congruent; 2 and 3 are not congruent; 2 and 4 are not congruent; 3 and 4 are congruent.
Step-by-step explanation:
From the diagram, we can see that the angle measures and side measures of figures 1, 3 and 4 are the same. This means that these three figures are congruent. Figure 2, however, is not congruent to any of the other 3.
Answer:
P=23.4
Step-by-step explanation:
so using the pytogoren theroum
c2-b2= a2
so a= 6.9
so P= 6.9+6.8+9.7=23.4

Answer:
F(x) = -3^(27)
According to the way the question was arranged, the answer above is the answer.
But the options given none of them matches my answer.
Step-by-step explanation:
A function is defined as (f of x)
= -3^4√x-9.
F(x)= -3^(4√x-9) at x= 81
√x= √81
√x= 9
F(x)= -3^(4(9)-9)
F(x) = -3^(36-9)
F(x) = -3^(27)
