The answer is 4.5 for the side length of the pentagon and 7.5 is the side length for the triangle because 7.5*3(3 sides) = 22.5 and 4.5*5(5 sides)= 22.5. The perimeter is 22.5
Answer:
C. 256^4 or 256 to the 4th power
Step-by-step explanation:
1. F(-4)= 2(-4^3) + 2
F(-4)= 2(-64) +2
F(-4)= -128 +2
So F(-4)= -126 is your answer
2. G(-7)= 2(-7)-3
G(-7) = -14 -3
So G(-7)= -17
Hope this helps
Answer:
a) ∅ ∈ {∅} TRUE
b) ∅ ∈ {∅,{∅}} TRUE
c) {∅} ∈ {∅} FALSE
d) {∅} ∈ {{∅}} TRUE
e) {∅} ⊂ {∅,{∅}} TRUE
f ) {{∅}} ⊂ {∅,{∅}} TRUE
g) {{∅}} ⊂ {{∅},{∅}}FALSE
Step-by-step explanation:
To assess whether these statements are true or false, first observe the symbol:
"∈" means that element, as it is and as it is, belongs to the set. To belong to the set it must be within the symbols "{}"
On the other hand, the symbol "⊂" means "subset", that is, it is a subset that is included in the main set.
So:
c) is false because "{∅}" is not included in the set
g) is false because " {{∅}}" is not included in the set
Answer:
5 c = 45 , d = 97
Step-by-step explanation:
5) You know the entire triangle has a total of 180 degrees, you also know that angle c + 135 has to equal 180.
So for angle C, you will set up your formula c=180-135 = 45
Now you set up your formula for angle d.
180=angle c + angle d +38
180 = 45 + D + 38 -> D = 180-45-38 = 97
