in the following expression, the variable truckweight has the value 70000 and the variable weightlimit has the value 80000.truck weight < weight limit what value does the expression evaluate to?

The distance travelled from Buffalo to Cleveland if the total cost of the move is $724.85 is  479.97

The base cost of the rental is said to be 49.95 dollars + 1.19 per mile

The cost of the gas is $3.89. The mileage of the truck is 18 miles

There would be an extra cost of

$3.89/18 per mile.

= 0.216111

In x miles we would have the equation that is written as:

C(x) = 49.95 + (1.19 + 0.21611)x

C(X) = $724.85 this is the total cost. Hence we would have

$724.85 =  49.95 + 1.19x + 0.21611x

$724.85 -   49.95 = 1.40611x

674.9 = 1.40611x

divide through by 1.40611

674.9 / 1.40611 = x

x = 479.97

The distance traveled is  479.97

The predicted strength of a weld with diameter of 51 is -503.16.

Given that diameter of weld is 51.

And we have to find predicted strength of a weld.

We know that the equation of predicted strength is,

strength = -941.6 + (8.598 × D)

where D id diameter = 51

⇒ strength = - 941.6 + (8.598 × 51)

   strength = -941.6 + 438.4

   strength = -503.2

Therefore predicted strength of a weld is -503.2 i.e option (b) -503.16.

A prediction equation predicts a value of the response variable for given values of the factors. The Delphi Survey technique is a popular method used in prediction. There are two types of prediction methods: qualitative and quantitative.

What is function ?

An expression, rule, or law in mathematics that specifies the relationship between an independent variable and a dependent variable (the dependent variable).

An example of a rule is a function, which produces one output for a single input. Alex Federspiel is the picture's author. Y=X2 is an illustration of this. You only get one output for y if you enter anything for x. The fact that x is the input value leads us to say that y is a function of x.

The base of the triangle is decreasing at the rate of 1.6 cm/min.

Given

dh/dt = 1 cm/min

dA/dt = 2 cm2/min

When A = 100 cm2, h = 10 cm

We know that

A = 1/2 × b × h

b = 20 cm

Let us differentiate both sides

dA/dt = 1/2 [b dh/dt + h db/dt]

Substituting the values

2 = 1/2 [20 × 1 + 10 × db/dt]

By further simplification

4 = 20 + 10 db/dt

db/dt = -1.6 cm/min

Therefore, the base of the triangle is decreasing at the rate of 1.6 cm/min.

(-9, 9) domain of the vector function. A vector valued function's domain is a subset of all real numbers at which the function is well-defined.

Consider the function y = f(x) to have an independent variable x and a dependent variable y. If a function f provides a way to successfully produce a single value y using a value for x, that chosen x-value is said to belong to f's domain.

A vector-valued function is a rule that gives each member of a subset of R1 a vector. A function's domain is the set of all possible inputs to the function. The domain of f(x)=x2 is all real numbers, for example, and the domain of g(x)=1/x is all real numbers except x=0.

Using the standard deviation value of these interarrival times, the coefficient of variation is 0.012.

The standard deviation is a statistic that expresses how much variance or dispersion there is in a group of numbers. While a high standard deviation suggests that the values are dispersed throughout a wider range, a low standard deviation suggests that the values tend to be close to the established mean.

The standard deviation to mean ratio, or coefficient of variation (CV), illustrates the degree of variability in proportion to the population mean. The dispersion increases with increasing CV.

The given equation 11= - 4x^2-x^3 is not quadratic. It is a cubic.

The definition of a quadratic as a second-degree polynomial equation demands that at least one squared term must be included. It also goes by the name quadratic equations. The quadratic equation has the general form ax^2 + bx + c = 0. where a, b, and c are numerical coefficients and x is an unknown variable.

Quadratic expressions are those involving powers of x up to the second power, not the fourth power, hence the prefix quad signifies "four" rather than "two."

As highest power with the variable is 3 so it is a cubic expression not a quadratic.

dimensions of the poster with margin are L  =  12 in and h  = 24 in

The shape/polygon of a rectangle is two dimensional, having four sides, four vertices, and four right angles. The rectangle's two opposing sides are equal and parallel to one another. The space a rectangle occupies is known as its area. The area of a rectangle can also be defined as the region inside its border.

We utilise the unit squares to calculate a rectangle's area. Rectangle ABCD should be divided into unit squares. The total number of unit squares that make up a rectangle ABCD is its area.

Rectangle area equals length times width.

Let call length of printed area of the poster be " x "  and  height of printed area of the poster be " y ".

Area of the poster = length and height

200 = x*y  

y = 200/x

We also know that dimensions of the poster with margin is:

L  =  x + 2   in  and     H  =  y + 4 in

Therefore area of the poster is:

A(p)  = ( x + 2 ) * ( y + 4 )

And area as function of x is:

A(x)  =   ( x + 2 ) * ( 200/x + 4 )

A(x)  =  200 + 4*x + 400 /x  + 8

Taking derivatives on both sides of the equation we have:

A´(x)  =  4 - 400/x²

By taking A´(x)  = 0

4 - 400/x² = 0 ⇒ 4*x² - 400 = 0

x² = 400 / 4

x² = 100

x = 10 in

and y = 200/x ⇒ y = 20

The second derivative A´´(x) = 400/x4 which is > 0

there is a minimum for the function at the point x = 10

As x and y are dimensions of the printing area of the poster, dimensions of the poster with margin are

L  = x  +  2   =   10  + 2  =  12 in   and

h = y  +  4   =   20  + 4  =  24  in

Let's compile what we know (what we are given).

An investment of $500 means that our principle amount P equals 500.

2.8% nominal yearly interest means that our rate r equals 0.028.

Compounded quarterly means that our compounded rate n equals 4.

So, we have:

[tex]\displaystyle\begin{aligned}P & = 500 \\r & = 0.028 \\n & = 4 \\\end{aligned}[/tex]

In order to find an equation that models the final amount A in terms of t years, we can simply substitute in our known variables:

The equation for a line that passes through points (2,1) and (0,7) is y-7 = -3x or y= -3x+7

To find the equation of a line passing through two points you must first find the slope of the line.

The slope can be found by using the formula: [tex]m=\frac{y2-y1}{x2-x1}[/tex]

Where m is the slope and (x1,y1) and (x2,y2) are the two points. Substituting the two points given in the problem allows us to calculate the slope as:

[tex]m=\frac{7-1}{0-2} \\m= \frac{6}{-2} \\m= -3[/tex]

Next, we have to use the point-slope formula to find the equation for the line passing through these two points.

The point-slope formula states: (y-y1)=m(x-x1)

Where m is the slope and x1, and y1 are points from which the line passes.

Substituting the value of m and x1 and y1 in the given equation,

y-7=-3(x-0)

y-7= -3x-3*0

y-7+-3x

Solving for the slope-intercept form gives:

y-7+7= -3x+7
