Find the value of x and y, given the following matrix equation: matrix x = y =
Answers
Based on the given matrix equation, the value of x and y are ±6 and 16 respectively.
How to determine the value of x and y.In order to solve for the value of x and y, we would create an equation from the upper and lower part of this matrix respectively.
x² - 4 = 32 ...........(upper part)
y + y - 4 = y + 6 ....(lower part)
Next, we would solve for x:
x² - 4 = 32
x² = 32 + 4
x² = 36
x = ±√36
x = ±6.
For the value of y, we have:
y + y - 4 = y + 6
2y - 4 = y + 6
2y - y = 6 + 10
y = 16.

A piece of copper (c = 0.385 joules over grams times degrees Celsius) undergoing a temperature change from 150°C to 225°C absorbs 3,500 joules of energy. What is the mass of the piece of copper? Express the answer to the nearest whole number. grams
Answers
The mass of the piece of copper, to the nearest whole number is 121 grams.
Given the following data:
Specific heat capacity of copper = 0.385 J/g°CInitial temperature = 150.0°CFinal temperature = 225.0°CQuantity of heat = 3,500 JoulesTo calculate the mass of the piece of copper, to the nearest whole number:
Mathematically, quantity of heat is given by the formula;
[tex]Q = mc\theta[/tex]
Where:
Q represents the quantity of heat.m represents the mass of an object.c represents the specific heat capacity.[tex]\theta[/tex] represents the change in temperature.Making "m" the subject of formula, we have:
[tex]m = \frac{Q}{c\theta}[/tex]
Substituting the given parameters into the formula, we have;
[tex]m = \frac{3500}{0.385(225-150)}\\\\m = \frac{3500}{0.385 \times 75} \\\\m = \frac{3500}{28.875}[/tex]
Mass, m = 121.21 ≈ 121 grams

By digging snow tunnels from their shelters to the tunnel.
What is tunnel?When you're gazing straight ahead, your peripheral vision, also known as side vision, is what you perceive on the edges of your visual field.
When this peripheral vision is compromised, tunnel vision results. If this occurs, you won't be able to see anything unless you are directly facing it.
Two different kinds of photoreceptors, or light-sensing cells, in the retina, called rods and cones, are the primary culprits in this kind of vision loss. By identifying light and communicating information to the brain, the retina aids with vision.
A brain injury may also result in tunnel vision. For instance, even if there is no injury to the eye itself, a stroke can harm the brain's visual system and result in tunnel vision.
