Answer:

Since there are 36 inches in 1 yard,313 by 36 .

So, 313 yards = 11,268 inches.

Step-by-step explanation:

There are 36 inches in one yard

To get your answer, you'll multiply 313 yards by 36 inches

=313×36

=11,268

So 313 yards=11,268 inches

Since there are 36 inches in 1 yard,313 by 36 .

So, 313 yards = 11,268 inches.

Since they are 36 inches in 1 yard,  multiply 313 by 36,  So 313 yards equal 120 inches.

Answer:

193.95 Canadian dollars

Step-by-step explanation:

Given: Each U.S. Dollar is worth 1.293 Canadian dollars and each Canadian dollar is worth 0.773 U.S. Dollar.

To find: Value of 150 U.S. dollars in terms of Canadian dollars

Value of 1 U.S. dollar = 1.293 Canadian dollars

To find 150 U.S. dollars in terms of Canadian dollars, multiply 150 by 1.293

Value of 150 U.S. dollars in terms of Canadian dollars = 150 × 1.293 = 193.95 Canadian dollars

By solving  the equation  x² + 5x - 14 = 0 get the value of x is 2 or -7.

Given,

In the question:

To solve the equation:

x² + 5x - 14 = 0

Now, According to the question:

x² + 5x - 14 = 0

Split the middle term into two terms :

x² - 2x + 7x  - 14 = 0

Factor the first two terms and the last two terms separately

x(x - 2) + 7 (x -2) = 0

Factor out

(x - 2) (x + 7) = 0

Apply Zero Product Property

x - 2 = 0 or x + 7 = 0

x = 2 or x = -7

Hence, By solving  the equation  x² + 5x - 14 = 0 get the value of x is 2 or -7.

Original width = 20

New width = 20 x 5 = 100

120 x 100 = 12000 ft^2

The value of P'(5) = 65 and  P'(6) = 65.

Mr. Wutz owns a hot dog business called 'Wutz upDogs.' The daily profit function is given by P(x) = 65x + 7, where x is the number of hot dogs sold.

To evaluate P'(6), the derivative of P(x) at x = 6, we need to use the power rule for derivatives. The power rule states that d/dx(xn) = nxn-1. Therefore, P'(6) = 65(6)1 = 65 dollars per hot dog.

To evaluate P'(5), the derivative of P(x) at x = 5, we use the same power rule. Therefore, P'(5) = 65(5)1 = 65 dollars per hot dog.

There are 33 different nonnegative integer solutions to the equation x₁ + x₂ + x₃ + x₄ + x₅ + x₆ = 30.

To find the number of different solutions, we can use a combinatorial approach. The equation x₁ + x₂ + x₃ + x₄ + x₅ + x₆ = 30 represents a partition of 30 into 6 nonnegative integers. We can visualize this as distributing 30 identical objects (representing the sum) into 6 distinct boxes (representing the variables), with the constraint that each box can have any nonnegative number of objects.

Using stars and bars method, we can solve this problem. Imagine representing the sum of 30 as a sequence of 30 stars (**************...). We can then place 5 bars to divide these stars into 6 groups, corresponding to the variables. The bars act as separators between the stars, determining the values of the variables. For example, if we have the sequence ***|***|*****|***|**|**, it means x₁ = 3, x₂ = 3, x₃ = 5, x₄ = 3, x₅ = 2, and x₆ = 2.

The number of different solutions is then equal to the number of ways to arrange the 30 stars and 5 bars. This can be calculated using the formula for combinations with repetition, which is (n + k - 1) choose (k - 1), where n is the number of stars and k is the number of bars. In this case, we have (30 + 5 - 1) choose (5 - 1), which simplifies to 34 choose 4. Evaluating this expression gives us the answer of 33 different solutions to the equation.

Step-by-step explanation:

We use the simple interest formula.

I = Prt

I = Interest

P = Principal (initial value)

r = Interest rate

t = Time (years)

P = $12,000

r = 6.5%  which we convert to a decimal by dividing by 100    6.5/100 = .065

t = 3 months    which we convert to years by dividing by 12    3/12 = 1/4 = .25

Plug in the values

I = 12000 * .065 * .25

I = $195 interest gained

Answer:

The slope of the line that divides the region bounded by the parabola \(y=5x-3x^2\)and the x-axis into two regions with equal area is 5.

To find the slope of the line that divides the region into two equal areas, we need to determine the point of intersection between the parabola and the x-axis. Since the line passes through the origin, its equation will be y = mx, where m represents the slope.

Setting the equation of the parabola equal to zero, we find the x-values where the parabola intersects the x-axis. By solving the equation\(5x - 3x^2 = 0\), we get x = 0 and x = 5/3.

To divide the region into two equal areas, the line must pass through the midpoint between these x-values, which is x = 5/6. Plugging this value into the equation of the line, we have y = (5/6)m.

Since the areas on both sides of the line need to be equal, we can set up an equation using definite integrals. By integrating the equation of the parabola from 0 to 5/6 and setting it equal to the integral of the line from 0 to 5/6, we can solve for m. After performing the integration, we find that m = 5.

Therefore, the slope of the line that divides the region into two equal areas is 5.

The curve is y = In(sec(x)) and we have to find its length. We are given the range as 0 ≤ x ≤ π/4. So, the formula for the length of the curve is given as:

To solve for the length of the curve of y = In(sec(x)), we use the formula,

`L = ∫[a,b] √[1+(f′(x))^2] dx`.Where, `a = 0` and `b = π/4`. And `f′(x)` is the derivative of `In(sec(x))`.

We know that:`f′(x) = d/dx[In(sec(x))]`

Using the formula of logarithm differentiation, we can write the above equation as:

`f′(x) = d/dx[In(1/cos(x))]`

So,`f′(x) = -d/dx[In(cos(x))]`

Therefore,`f′(x) = -sin(x)/cos(x)`

Substituting the values, we get:

`L = ∫[a,b] √[1+(f′(x))^2] dx`

`L = ∫[0,π/4] √[1+(-sin(x)/cos(x))^2] dx`

`L = ∫[0,π/4] √[(cos^2(x)+sin^2(x))/(cos^2(x))] dx`

`L = ∫[0,π/4] sec(x) dx`

Now, `L = ln(sec(x) + tan(x)) + C` where `C` is a constant.

We calculate the constant by substituting the values of `a = 0` and `b = π/4`:

`L = ln(sec(π/4) + tan(π/4)) - ln(sec(0) + tan(0))`

`L = ln(√2 + 1) - ln(1 + 0)`

`L = ln(√2 + 1)`

Thus, the exact length of the curve is `ln(√2 + 1)` units.

Thus, the exact length of the curve of y = In(sec(x)), 0≤x≤π/4 is `ln(√2 + 1)` units.

Evaluate the function at critical points and endpoints. The highest value is the absolute maximum, and the lowest is the absolute minimum.

To find the absolute extrema of a function, we need to evaluate the function at critical points and endpoints of the given interval.

If no interval is specified, we consider the entire domain of the function, which is the set of real numbers (-∞, +∞).

The absolute extrema occur at the highest and lowest points on the graph.

To determine the extrema, follow these steps:

Find the critical points by taking the derivative of the function and setting it equal to zero.

Evaluate the function at the critical points and endpoints.

The highest value is the absolute maximum, and the lowest value is the absolute minimum.

Note the x-values at which these extrema occur.

By applying these steps, we can determine the absolute extrema of the function over the specified interval or the entire real number line.

It will take 120 minutes for smaller hose to fill the complete swimming pool on its own.

Let us represent the complete swimming pool as 1. Now, total time required to fill the swimming pool is 40 hours. So, amount of swimming pool filled in 1 minute = 1/40

Similarly, amount fo swimming pool filled by larger hose in 1 minute = 1/60

Now for the smaller hose, the amount of swimming pool filled in 1 minute = 1/40 - 1/60

The amount of swimming pool filled in 1 minute = (60 - 40)/2400

The amount of swimming pool filled in 1 minute = 20/2400

The amount of swimming pool filled in 1 minute = 1/120

Total time taken to fill swimming pool = 1 ÷ (1/120)

Total time taken to fill swimming pool = 120 minutes

An explanation for this is that if there are too many positive or negative response options, respondents may feel pressured to choose a certain option even if it doesn't accurately reflect their true opinion. This can result in inaccurate data and can skew the results of the survey or study.
