Answer:

go up 5, and up 4 more and to the right one. so one p oint at 5 on the y axis and one point at 9,1 on the y axis.

Step-by-step explanation:

the slope should be positive as well.

Answer:

Read my step-by-step explanation

Step-by-step explanation:

So your y-intercept will be 5, so you plot your starting point at +5 on the y-axis. Then since you have a negative slope (-4x) So you would start at your plotted 5, and slope goes rise over run. So you would go 4 down to the right and down one, about 2 times and plot your point.

The limit of the function as x approaches -2 is 20.To find the limit of the function (if it exists), we can substitute the given value into the function and simplify. Given function: f(x) = 4x² + 5x - 6x + 2

To find the limit as x approaches -2, we substitute -2 into the function:

f(-2) = 4(-2)² + 5(-2) - 6(-2) + 2
      = 4(4) - 10 + 12 + 2
      = 16 - 10 + 12 + 2
      = 20

Therefore, the limit of the function as x approaches -2 is 20.

To write a simpler function that agrees with the given function at all but one point, we can use a graphing utility. By plotting the given function and observing its behavior, we can create a simpler function that matches the original function except at one point.

However, without further information about the specific behavior of the given function, it is not possible to provide a more detailed explanation or a graph of the simpler function.

The missing lengths of the triangle are solved

a) x = 3√5

b) y = ( 3√15 ) / 2

Given data ,

Let the triangle be represented as ΔABC

The measure of ∠ABC = 60°

Now , from the trigonometric relations , we get

cos θ = adjacent / hypotenuse

On simplifying , we get

cos 60° = [ ( 3√5 )/2 ] / x

( 1/2 ) =  [ ( 3√5 )/2 ] / x

Multiply by x on both sides , we get

x =  ( 3√5 )/2

Now , the value of y is calculated from the trigonometric relation ,

sin θ = opposite / hypotenuse

sin 60° = y / ( 3√5 )

Multiply by ( 3√5 )/2 on both sides , we get

y = ( √3/2 ) x ( 3√5 )

y = ( 3√15 ) / 2

hmm let's do that with synthetic division, Check the picture below.

11,250 feet² is the largest total area.

Describe Area?

The region enclosed by an object's shape is referred to as the area.

                      The area of the shape is the area that the figure or any other two-dimensional geometric shape occupies in a plane.

Let x, y are length and width of the total area .

Given that there is 600 feet of fence to enclose it.

    600 = x + x + y + y + y + y

      600 = 2x + 4 y

      600 = 2 ( x + 2y )

      300 = x + 2y

area of the field A = Length * width

                      A = xy

                 A = ( 300 - 2Y ) Y

             A = 300y - 2y²

               A' = d/dy (A)

                  = d/dy ( 300y - 2y² )

                   = 300 (1) - 2 (2y)

                    = 300 - 4y  ..................2

also A'' = d/dy(A') = d/dy ( 300 - 4y )  .............. from 2

                        =  0 - 4 (1)

                  A'' = 4        ....................3

 Take        A'  =  0

          300 - 4y = 0

       300 = 4y

             y = 75

also at    y = 75    ,  A'' = - 4

                                     < -4

at  y = 75, A' = 0 , A'' < 0

    By second derivative test A   hAS MAX VALUE

       When  y = 75

   also  x = 300 - 2y

            x = 300 - 2 * 75

            x = 300 - 150

            x = 150

largest area   =  A ∫x = 150  y = 75

Hope this helps

Answer:

The answer is A you guy's

Between the points (9, 5) and (5, 4), the supplied line must have a 1/4 slope.

A line's tangent angle to the horizontal creates the slope of the line. Specifically, m = tanx, with x in degrees.

The line that intersects (9, 5) and (5, 4).

Given as m = (y2 - y1) / (x2 - x1), the slope of the line.

If spring A has a spring constant which is 8 times spring B's spring constant then the ratio of their periods is = 9K and  \(\frac{9K}{8}\)

Spring stiffness is a characteristic that describes the relationship between load and deflection. If k is stiffness, P is load, and x is deflection, P = kx. The smaller the deflection at a constant load, the stiffer the spring, k.

Given that,

If spring A has a spring constant which is 8 times spring B's spring constant,

Let us assume,

A spring is cut into two parts of length La and Lb

Also given that La : Lb

La : Lb = 1 : 8

The total of spring constant is = 1 + 8 = 9

If the length of spring is L , then La

La = \(\frac{L}{9}\)

And length of B , Lb

Lb = \(\frac{8L}{9}\)

We know, for spring force , spring constant or stiffness of spring is inversely proportional to length of spring .

K ∝ 1 / L

If initial spring constant is k then,

kL= KaLa = KbLb

Then,

Ka = \(\frac{K}{\frac{1}{9} }\)

Ka = 9K

And Kb = \(\frac{K}{\frac{8}{9} }\)

Kb = \(\frac{9K}{8}\)

Hence, stiffness of A is given by, 9K

Stiffness of B is given by  \(\frac{9K}{8}\)

Therefore,

If spring A has a spring constant which is 8 times spring B's spring constant then the ratio of their periods is = 9K and  \(\frac{9K}{8}\)

Answer:

factors are (x-1),(x+2),(x+4),(x+3)

Answer:

x = -7

x = 5

Step-by-step explanation:

The standard form of quadratic equations is

Ax^2 + Bx + C = 0

The factors need to multiply together to be C and add together to be B.

The two numbers that will multiply together to be -35 and add together to be 2 are -5 & 7.

The factor pairs are (x+7)(x-5). Zero product property means we set each of those factor pairs = 0 and solve.

x + 7 = 0

-7 -7 Subtract 7 from each side to solve

x = -7

x - 5 = 0

+5 +5 Add 5 to each side to solve

x = 5

To solve the equation, factor x²+2x−35 use the formula x² +(a + b) x + ab = (x + a)(x + b). To find a and b, set up a system to be solved.

a + b = 2

ab = −35

Since ab is negative, a and b have opposite signs. Since a+b is positive, the positive number has a greater absolute value than the negative. Show all pairs of integers whose product is −35.

Calculate the sum of each pair.

The solution is the pair that gives sum 2.

Rewrite the factored expression (x + a)(x + b) with the values obtained.

To find solutions to equations, solve x−5=0 and x+7=0.

Answer:

The probability is 0.5714

Step-by-step explanation:

This is a probability question. We are interested in calculating the probability that a random electrical engineering student is from section A.

Mathematically the probability will be;

Number of electrical engineering students in section A/ Total number of electrical engineering students in both sections

Total number of electrical engineering students = 128 - 60 -40 = 28

Now let’s calculate the number of electrical students from section A

Number of mechanical and electrical = 50-18 = 32

Now, there are a total of 60 mechanical engineers and 44 in B; So the number of mechanical engineers in A = 60-44 = 16

So the number of electrical engineers in A = 32-16 = 16

So the probability will be;

16/28 = 4/7 = 0.5714

An order-preserving function is one where x < y implies f(x) < f(y). An isomorphism is a one-to-one order-preserving function between two partially ordered sets, while an automorphism is an isomorphism of a set to itself.

In the given excerpt, it explains the concepts of order-preserving functions, isomorphisms, and automorphisms in the context of partially ordered sets.

Order-Preserving Function:

A function f: P -> Q, where P and Q are partially ordered sets, is said to be order-preserving if for any elements x and y in P, if x < y, then f(x) < f(y). In other words, the function preserves the order relation between elements in P when mapped to elements in Q.

Increasing Function:

If P and Q are linearly ordered sets, then an order-preserving function is also referred to as an increasing function. It means that for any elements x and y in P, if x < y, then f(x) < f(y).

Isomorphism:

A one-to-one function f: P -> Q is called an isomorphism of P and Q if it satisfies two conditions:

a. f is order-preserving: For any elements x and y in P, if x < y, then f(x) < f(y).

b. f is onto (surjective): Every element in Q has a pre-image in P.

When an isomorphism exists between (P, <) and (Q, <), it means that the two partially ordered sets have a structure that is preserved under the isomorphism. In other words, they have the same ordering relationships.

Automorphism:

An automorphism of a partially ordered set (P, <) is an isomorphism from P to itself. It means that the function f: P -> P is both order-preserving and bijective (one-to-one and onto). Essentially, an automorphism preserves the structure and order relationships within the same partially ordered set.

These concepts are fundamental in understanding the relationships and mappings between partially ordered sets, particularly in terms of preserving order, finding correspondences, and exploring the symmetry within a set.

Given:

Rate of sales tax = 7%

Marked price of an item = $19.94

To find:

The final cost of the item once tax is included.

Solution:

We have,

Rate of sales tax = 7%

Marked price of an item = $19.94

\(\text{Sales tax}=\dfrac{7}{100}\times 19.94\)

\(\text{Sales tax}=1.3958\)

Now, final cost of the item once tax is included is

\(\text{Final cost}=\text{Marked price}+\text{Sales tax}\)

\(\text{Final cost}=19.94+1.3958\)

\(\text{Final cost}=21.3358\)

Therefore, the final cost of the item once tax is included is $21.3358.
