0 -17k2+10k4-14k-14
O 6k4-14k2 +7k-14
Answer:
-7k
Step-by-step explanation:
(−102+7k+6×4)+(−14−464−14k)
Multiply 6 and 4 to get 24.
−102+7k+24−14−464−14k
Add −102 and 24 to get −78.
−78+7k−14−464−14k
Subtract 14 from −78 to get −92.
−92+7k−464−14k
Subtract 464 from −92 to get −556.
−556+7k−14k
Combine 7k and −14k to get −7k.
−556−7k
Which of these represents the conjugate of the impedance of a circuit written as 7 – i ohms?
A
–7 – i ohms
B
–7 + i ohms
C
–7i ohms
D
7 + i ohms
For the expression 7 - i ohms, the conjugate will be 7 + i ohms (the sign was changed from negative to positive)
The impedance of the circuit is written in form of a complex number.
The standard representation of a complex number is expressed as a + ib where:
a is the real part
ib is the imaginary part
The conjugate of the complex number a + ib will be a - ib. Note that the signs of the expression were changed from addition to subtraction.
Similarly for the expression 7 - i ohms, the conjugate will be 7 + iohms (the sign was chaged from negative to positive)

Find the angle of C
Answer:

Step-by-step explanation:
Answer:
∠ C ≈ 22.6°
Step-by-step explanation:
Since Δ ABC is right at B
Using the sine ratio in the right triangle
sinC = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{AB}{AC}[/tex] = [tex]\frac{5}{13}[/tex] , then
∠ C = [tex]sin^{-1}[/tex] ( [tex]\frac{5}{13}[/tex] ) ≈ 22.6° ( to 1 dec. place )

Answer:
28°
Step-by-step explanation:
1. We can see that ∠GFH has two smaller angles within it: ∠1 and ∠2. Given that m∠GFH is 53° (the whole thing), and m∠2 is 25° (a part of it), we just have to subtract 25 from 53 to get the measure of ∠1.

Mateo jogs for 3 3/4 miles on Saturday and 4 2/5 miles on Sunday. What is the total distance, in miles, that Mateo jogged in the past 2 days?
Answer:
Mateo jogged 8 3/20 miles in the past 2 days.
Step-by-step explanation:
Given:-
Distance on Saturday = 3 3/4
Distance on Sunday = 4 2/5
Total distance = 3 3/4 + 4 2/5
= 15/4 + 22/5

Answer:8+ (3/20)
Step-by-step explanation: We will assume that "today" is a Monday.
3+(3/4) + 4+(2/5)
7 + (3/4) + (2/5)
7 + (3/4)*(5/5) + (2/5)*(4/4)

What is the iterative rule for the following sequence?
4, 4/5, 4/25, 4/125, ...
A.) an=4•(1/5)^n-1
B.) an=4•(1/5)^n
C.) an=1/5•4^n-1
D.) an=1/5•4^n
Answer:
A.) 4 * (1/5)^(n-1)
Step-by-step explanation:
a1 = 4 * (1/5)^(1-1) = 4* (1/5)^0 = 4*1 = 4
a2 = 4 * (1/5)^(2-1) = 4 * (1/5)^1 = 4 * 1/5 = 4/5
a3 = 4 * (1/5)^(3-1) = 4 * (1/5)^2 = 4 * 1/25 = 4/25
a4 = 4 * (1/5)^(4-1) = 4 * (1/5)^3 = 4 * 1/125 = 4/125
a5 = 4 * (1/5)^(5-1) = 4 * (1/5)^4 = 4 * 1/625 = 4/625
. . .
The required iterative rule for the following sequence is [tex]a_n=4*(1/5)^{n-1}[/tex]. Option A is correct.

Find the missing side of each triangle. Round your answers to the nearest tenth if necessary. (Please Show your work)
Answer:
x = + 14.88 km
Step-by-step explanation:
Let's solve for x using the Pythagorean Theorem.
The length of the hypotenuse is 15.8 km; that of the shorter leg is 5.3 km.
Since a² + b² = c², we get:
(5.3 km)² + x² = (15.8 km)²
Solving for x², we obtain (15.8 km)² - (5.3 km)² = 249.64 km² - 28.09 km²
The last expression returns the value 221.55 km² for x²
Taking the square root of both sides, we get x = + 14.88 km
