Answer:
A triangle with two congruent sides and two congruent angles ( base Angles) is called isosceles triangle.
His error is in step 3. The variable x is being multiplied by -7 and therefore he should have divided both sides by -7, not 7 as he did.
Answer:
1. V(12) = $ 1200
2. V(20) = $ 4800
Step-by-step explanation:
The following data were obtained from the question:
V(t) = 150 × 2ᵗ/⁴
V(12) =?
V(20) =?
1. Determination of V(12)
Time (t) = 12 years
V(12) =?
V(t) = 150 × 2ᵗ/⁴
V(12) = 150 × 2¹²/⁴
V(12) = 150 × 2³
V(12) = 150 × 8
V(12) = $ 1200
2. Determination of V(20)
Time (t) = 20 years
V(20) =?
V(t) = 150 × 2ᵗ/⁴
V(20) = 150 × 2²⁰/⁴
V(20) = 150 × 2⁵
V(20) = 150 × 32
V(20) = $ 4800
Answer:
The Statement D⊆B is False.
Step-by-step explanation:
Given:
A = {1, 3, 5, 7 }
B = {5, 6, 7, 8}
C = {5, 8}
D = {2, 5, 8}
U = {1, 2, 3, 4, 5, 6, 7, 8}
To Check:
D⊆B = True or False
Solution:
The sign '⊆' symbolize SUBSET
So D⊆B means D is the Sub Set of B
That means All the element of Set D must be there in the SET of B Then it comes True.
Or else it is False
D = {2, 5, 8}
B = {5, 6, 7, 8}
Therefore D⊆B is a FALSE statement
For it to be TRUE we must have set B as
D = {2, 5, 8}
B = {2,5, 6, 7, 8}
Now D⊆B is a TRUE statement
