The equation of a line perpendicular to y=4/24x that pass through the point (-8, -4) is -6x-4y=16 where x-intercept is -6 and y-intercept is -4.

A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included. The variables in the preceding equation are y and x, and it is occasionally referred to as a "linear equation of two variables.

The formula for a straight line is y=mx+c where c is the height at which the line intersects the y-axis, often known as the y-intercept, and m is the gradient.

Given line ;

y=1x/6

now comparing it with y=mx+c to find the value of m and we found;

m1=1/6

now if two lines are perpendicular then,

m1.m2=-1

m2=-6

now finding the equation of line passing through the point (-8, -4)

x1=-8

y1=-4

(y−y1)=m(x−x1)

Y+4=(-6)(x+4)

Y+4=(-6x/4)

Y=(-6x/4)-4

Y=(-6x-16)/4

4y=-6x-16

rearrange;

-6x-4y=16

this is our required value.

Answer:

15

Step-by-step explanation:

To find the total number of combinations you can make with these four coins, we have to do 2 to the power of the total amount of coins. This because each coin has two choices: to be included in the combination or not. There are 4 total coins, and 2^4 is 16. There are 16 total combinations. But since one of those possibilities are that none of the coins are included, we subtract 1 from the total, and get 15. There are 15 combinations with 1 or more coins, which each give us different amounts.

By factor theorem (v+5) is not a factor of the given polynomial f(v).

What does factor theorem mean?

When thoroughly factoring the polynomials, mathematicians apply the factor theorem. The polynomial's zeros and factors are connected by this theorem.

                   The factor theorem states that if a is any real number and f(x) is a polynomial of degree n 1 then (x-a) is a factor of f(x) if f(a)=0.

The factor theorem states that

f(x) has a factor (x-k) if and only if f(k) = 0

We are given the following information.

F(v) = v 4 + 16v 3 + 8v 2 - 725

        We have to check whether (v+5) is a factor of given polynomial.

( v + 5 ) = ( v - ( - 5 )

 f( -5 ) = [tex]( -5 )^{4} + 16( -5)^{3} + 8( -5)^{2} - 725[/tex]

The measure of the angle ∠SRW will be 95°.

The inclination is the separation seen between planes or vectors that meet. Degrees are another way to indicate the slope. For a full rotation, the angle is 360 °.

Vertically opposite angle - When two lines intersect, then their opposite angles are equal.

2 converging lines are shown. A line with focuses TRW converges a line with focuses SRV at point R. The angle ∠TRV is 95 degrees.

The angle ∠TRV and the angle ∠SRW are opposite angles. Then we have

∠TRV = ∠SRW

∠SRW = 95°

The number of chickens that can be fed with 140 kg of corn is 2800.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x = 8 is an equation.

We have,

250 kg corn  = 5000 chicken

Multiply 140/250 on both sides.

140 kg of corn = 140/250 x 5000 chicken

140 kg of corn = 2800 chicken

Thus,

2800 chickens can be fed with 140 kg of corn.

Step-by-step explanation:

Using mathematical operations, we know that 27/4 pounds of Ham are still left with M.D.

An operation is a function in mathematics that transforms zero or more input values into a clearly defined output value.

The operation's arity is determined by the number of operands.

Most people believe that addition, subtraction, multiplication, and division are the four basic operations in mathematics.

So, we know that:
M.D. bought 8½ pounds of Ham.

He gave 1¾ pounds to Mr. Chavir.

Remaining Ham with M.D.:

8½ - 1¾

16+1/2 - 4+3/4

17/2 - 7/4

34 - 7/4

27/4

Therefore, using mathematical operations, we know that 27/4 pounds of Ham are still left with M.D.

The solution of the trigonometric equation is x = 26.57° or 153.43°

A trigonometric equation is an equation that contains the trigonometric ratios.

Given the trigonometric equation 2cos x - sin x = 3/(2cos x + sin x)

We solve for x in the equation. We proceed as follows.

Since 2cos x - sin x = 3/(2cos x + sin x)

Multiplying both sides by (2cos x + sin x), we have that

(2cos x - sin x)(2cos x + sin x) = 3

Now, we know that (a² - b² = (a + b)(a - b)

Applying this where a = 2cosx and b = sinx, we have that

(2cos x - sin x)(2cos x + sin x) = 3

(2cos x)² - (sin x)² = 3

4cos² x - sin² x = 3

Since sin²x = 1 - cos²x, substituting this into the equation, we have that

4cos² x - sin² x = 3

4cos² x - (1 - cos²x) = 3

4cos² x - 1 + cos²x = 3

4cos² x + cos²x  = 3 + 1

5cos²x  = 4

cos²x  = 4/5

Taking square root of both sides, we have that

cosx  = ±√(4/5)

cosx  = ±2/√5)

cosx  = ±2/√5 × √5/√5

cosx  = ±2√5/5

Taking inverse cosine of both sides, we have

x = cos⁻¹(±2√5/5)

x = cos⁻¹(±0.8944)

x = cos⁻¹(0.8944) or x = cos⁻¹(-0.8944)

x = 26.57° or (180 - 26.57)°

x = 26.57° or 153.43°

So, the solution is x = 26.57° or 153.43°

We infer that x and y's relationship is a non-linear function as a result. The relationship between x and y is a non-linear function.

A relation between a collection of inputs and outputs is known as a function. A function is, to put it simply, a relationship between inputs in which each input is connected to precisely one output. Four main categories can be used to classify different sorts of functions. One to one function, many to one function, onto function, one to one and into function—all based on the element.

Here,

Edge Length, x            Surface Area, y

1                                             6

2                                            24

3                                            54

4                                             96

Because each input value has one and only one output value, the data in the table unmistakably indicate a function. In other words, the x values are not repeated.

Additionally, it is evident from the table numbers and the graph that the function is not linear because the graph is not a straight line. Additionally, the largest power over the x variable(s) in a cubic function is 3. It is not a linear function, therefore.

As a result, we draw the conclusion that x and y's relationship is a non-linear function.

In essence, percentages are fractions with a 100 as the denominator. We place the percent symbol (%) next to the number to indicate that the number is a percentage. For instance, you would have received a 75% grade if you answered 75 out of 100 questions correctly on a test (75/100). Rather than being expressed as a fraction, a percentage is a piece of a whole expressed as a number between 0 and 100. Nothing is zero percent; everything is 100 percent; half of something is 50 percent; and nothing is zero percent.
