Which statement correctly applies mathematical reasoning to find the possible values for x in the equation x − 1.2 = 1.6 and you get this

 For recording the angular velocity we will use

     angular velocity, ω = dθ /dt

Angular velocity:

Angular velocity is a vector quantity, expressed as the angular velocity or rotational speed of an object and the rate of change of angular displacement that specifies the axis about which the object rotates. The amount of change in a particle's angular displacement over time is called its angular velocity. The trajectory of the angular velocity vector is usually perpendicular to the plane of rotation in the direction given by the right-hand rule.

Total Moment of Inertia:

The total moment of inertia is the sum of the moments of inertia of the mass elements in the body.

Unlike mass, which is a constant for a given body, the moment of inertia depends on the location of the center of rotation. In general, the moment of inertia is calculated by using integral calculus.

Thin cylindrical shell open at both ends, radius r, mass m.

This formula assumes that the thickness of the shell is negligible. This is a special case of a thick-walled cylindrical tube with r1=r2. A point mass m at the end of a rod of length r has the same moment of inertia and the value r is called the radius of gyration.

Correlation is a statistical measure that expresses the extent to which two variables are linearly related (meaning they change together at a constant rate). It's a common tool for describing simple relationships without making a statement about cause and effect.

Calculation for the correlation of the returns,

Using this formula,

Covariance of the returns = Correlation coefficient between the returns*Stock returns standard deviation*Mod T Stock returns standard deviation

The sample standard deviations of the rates of return for stock x and stock y were 0.20 and 0.12

The sample covariance between the returns of x and y is 0.0096.

Let plug in the formula

Covariance of the returns = Correlation * (0.20) * (0.12)

0.0096 = Correlation * (0.20) * (0.12)

0.0096 = Correlation * 0.024

0.0096 / 0.024 = Correlation

The expression that could be used to determine the length of segment AB in the triangles given is: A. AB = AX * AC/AY.

When two triangles are stated to be similar to one another, it means both triangles have equal corresponding angles, but their corresponding sides have proportional lengths or have ratios that are equal.

This means similar triangles have the same shape but different sizes, since their corresponding side lengths have proportional length.

Given that triangle AXY is similar to triangle ABC, it means that:

m<A = m<A

m<X = m<B

m<Y = m<C

AX/AB = AY/AC = XY/BC

To find the length of AB, we could use the following expression derived from the ratios stated above:

AX/AB = AY/AC

Cross multiply:

(AB) * (AY) = (AX) * (AC)

Divide both sides by AY

(AB) * (AY) / AY = (AX) * (AC) / AY

AB = AX * AC/AY

The expression to use is: A. AB = AX * AC/AY

The minimum lateral surface area of the prism is approximately 1.194 square units.

The given base and height of the prism is y and x respectively.

Hence volume of the prism

V = 1/3 x²y

again 1/3 x²y  = 1/6

or, y = 1/2x²

The lateral surface area of the prism is given by :

F = √(4y²+x²)

By the equation 1 we get :

F = x √ (1/x⁴ + x²)

Now we will use differentiation:

[tex]\frac{df}{dx} = \frac{2x^6-1}{x^4(x^2+\frac{1}{x^2} )}[/tex]

Now for the critical points we have to take df/dx = 0

In order to find the value of f(-1), you can start by finding the value of f(1) and then proceed for the next step.

As you have already noted, writing z13+z14 as e13(ln|z|+iθ(z)+i2nπ)+e14(ln|z|+iθ(z)+i2mπ) will not give you a specific branch. Instead, you can write z13+z14 as follows:

(z-1)(z12+z11+z10+...+1)

Then, you can use the fact that f(1)=0 to solve for the value of z12+z11+z10+...+1. This will give you a specific value for f(1).

To find the value of f(-1), you can use the following relationship:

f(-1) = f(1) * (-1)13 * (-1)14

Substituting the value you found for f(1) and evaluating the expression will give you the value of f(-1).

As for the condition "not defined on the negative imaginary axis", this means that the branch of f(z) is not defined for any complex number with a negative imaginary part.

What is an isosceles triangle?

In an isosceles triangle, the two base angles are congruent, or equal in measure.

In addition, the sum of the measures of the angles in any triangle is always 180 degrees. Therefore, we can set up an equation to find the measure of each angle in the triangle:

m∠D + m∠F + m∠E = 180 degrees

Substituting the given values for the measures of angles D and F, we get:

(5x+26) + (3x+63) + m∠E = 180

Combining like terms and solving for m∠E, we find that:

m∠E = 180 - (5x+26) - (3x+63)

= 180 - 8x - 89

= 91 - 8x

Therefore, the measure of angle E is 91 - 8x degrees.

To find the measure of angles D and F, we can substitute this value back into the equation:

m∠D + m∠F + m∠E = 180

(5x+26) + (3x+63) + (91-8x) = 180

Solving for x, we find that x = 6.

m∠D =5(6) + 26 = 30 + 25 = 56°

m∠F = 3(6) + 63 = 18 + 63 = 81°

Answer:

The number of degrees Celsius goes down 6 every week. (-6)

Step-by-step explanation:

If the city's temperature changed the same every week, and over the period of 2 weeks it changed -12 degrees Celsius, we need to figure out how much it changed every week (c). We can do this by dividing the number of weeks (w), by the total number of Celsius it changed (t).

The equation will look something like this:

w ÷ t = c

Fitting the numbers into this equation will look something like this:

2 ÷ -12 = -6

Every week, it changed -6 degrees Celsius.

Simplifying the expression, every week it changed -6 degrees Celsius. We know this because the temperature changes the same amount every week. So if the total amount is -12, we have to divide that by 2 to get -6.

a) The rate in feet per second is 148.5 feet per second

b) The distance covered after 2 feet is 360.4 feet

We know that the rate has to do with how much the quantity is changing per unit time. In this case, we are looking at the rate of change of the Parachute's distance per second. It is important for us to say that this rate of change of the distance can also be shown to be the speed of the object.

We would now convert the rate to feet per second and we have;

1 meter per second = 3.3 feet per second

45 meters per second = 45 * 3.3/1

= 148.5 feet per second

Then we have;

s = ut + 1/2gt^2

s =distance

u = initial velocity

g = acceleration due to gravity

t = time taken

After 2 seconds;

Step-by-step explanation:

If p and q are parallel, then the two angles in question should be equal to one another.

So,

(3x+15)°=(8x-10)°

(3x+15)°+10°=(8x-10)°+10°

(3x+25)°=(8x)°

(3x+25)°-(3x)°=(8x)°-(3x)°

25°=5x°
