Answer:
Y = [-6 6 6 -6]
Step-by-step explanation:
From the given matrices
If X - 2Y = Z
b - 2c = a ... 1
a -2d = c ...2
4+2a = 16.... 3
a + 2b = b .... 4
From3 ;
2a = 16-4
2a = 12
a = 6
From 4;
a + 2b - b = 0
a+b = 0
a = -b
6 = -b
b = -6
From1;
b - 2c = a
-6 - 2c = 6
-2c = 12
c = -6
also
a - 2d = c
6-2d = -6
-2d = -6-6
-2d = -12
d = 6
Hence the matrices Y = [-6 6 6 -6]

2. A spy uses a telescope to track a rocket launched vertically from a launch pad 6 km away. The rocket travels upwards at a velocity of 21.6 km per minute. Find the rate of change of the distance between the spy and the rocket when the rocket is 8 km in the air. Answer: 17.28 km/mim
NEED HELP ASAP
Answers
Answer:
The rate of change in distance between the spy and the rocket is 10.8 km/min,
or about 180 m/sec.
Step-by-step explanation:
At "Time=0" the rocket is 6km from the spy.
The rocket travels vertically 8km in about 0.37 minutes, calculated by 8km÷21.6km/min.
At that point, the rocket is 10 km from the spy., calculated by 6²+8²=10²
The difference is 4 kiilometers over 0.37minutes, about 22.2 seconds
Divide Distance by Time to get Rate:
4km/0.37min = 10.8 km/min
That is about 180 meters per second.

If a Customer places an order for $47.36 and it’s late, then how much would the customer be refunded if the refund is 20% on the total
Answers
I just multiplied the total by the refund percentage to get that number. It’s just like finding a tip.
The amount of the money refunded to the customer will be $9.472.
What is the percentage?
The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.
Given that a Customer places an order for $47.36 and it’s late. The refund is 20% of the amount.
The refunded amount will be calculated by multiplying the total amount by the percentage of the refund,
Refund = $47.36 x 0.2
Refund = ( $9.472 )
Therefore, the refunded amount will be $9.472.

Answer:
10 cm
Step-by-step explanation:
The diameter of the cylinder is 6 cm, so the length designated 'c' is the hypotenuse of a right triangle with legs 6 cm and 8 cm.
The Pythagorean theorem tells you the hypotenuse is ...
c^2 = (6 cm)^2 + (8 cm)^2 = 100 cm^2
c = √(100 cm^2) = 10 cm
The value of c is 10 cm.

-3(x-14) + 9x = 6x + 42
Answers
Answer:
All real numbers are solutions.
Step-by-step explanation:
Let's solve your equation step-by-step.
−3(x−14)+9x=6x+42
Step 1: Simplify both sides of the equation.
−3(x−14)+9x=6x+42
(−3)(x)+(−3)(−14)+9x=6x+42(Distribute)
−3x+42+9x=6x+42
(−3x+9x)+(42)=6x+42(Combine Like Terms)
6x+42=6x+42
6x+42=6x+42
Step 2: Subtract 6x from both sides.
6x+42−6x=6x+42−6x
42=42
Step 3: Subtract 42 from both sides.
42−42=42−42
0=0
Answer:
all real numbers
Step-by-step explanation:
-3 (x - 14) + 9x = 6x + 42
-3 (x - 14) + 9x - 6x = 6x - 6x + 42
-3 (x - 14) + 3x = 42
-3 (x) - 3 (-14) + 3x = 42
-3x + 42 + 3x = 42
3x - 3x + 42 = 42
42 = 42
