Answer:
50
Step-by-step explanation:
and 
can be expressed in complex form, with 
= i
= 
= 
× = 8i
= 
= 
× = 4i
the factors can then be expressed as
(6 + 8i)(3 - 4i) ← expand using FOIL
= 18 - 24i + 24i - 32i² [ i² = ( )² = - 1 ]
= 18 - 24i + 24i + 32 ← collect like terms
= 18 + 32 + 0
= 50
Answer:
1. 25
2. 10
3. 250
Step-by-step explanation:
Distance formula :√ (x2 - x1)² + (y2 - y1)² √ ()² + ()²
1. LENGTH OF AB :
A = 15,18
B = -5,3
√ (-5 - 15)² + (3 - 18)²
= √ 400 + 225
= 25
2. LENGTH OF AD :
A = 15,18
D = 21,10
√ (21 - 15)² + (10 - 18)²
= √36 + 64
= 10
AREA :
A=w x l
10 x25 = 250
Answer:
-3.1=x or x=-3.1
Step-by-step explanation:
Equation: 5.1=-3x-4.2
Adding 4.2 on both sides
5.1=-3x-4.2
+4.2 +4.2
Which equals:
9.3/-3=-3x/-3
Divide -3 on both sides:
-3.1=x or x=-3.1
Hope this helps!
Answer:
96
Step-by-step explanation:
To find this answer, I just did a bit of guess and check. I took 71+65+x (random numbers in the general area of those numbers). Then I divided that by 3 to find the average of the three numbers. So, (71+65+96)/3=77.(3). (95 is too small because its exactly 77 when the average is found.) Hope this helped!
Answer:
Option B
Step-by-step explanation:
log x=2
x = 10^2
Therefore, the exponential form is the one in option B
