A grocery store in town marks up the price of fresh strawberries in the winter by 15%. A drought causes an additional increase of $2.50 for each carton of strawberries. Let s represent the cost of one carton of strawberries. Write a function M(s) to represent the price of strawberries after the 15% markup.

Hence, the required value of the line integral is\($\boxed{-84550}$\).

The given line integral is \($\int_{C}xyz ds$\), where the given curve C is \($x=8\sin t$, $y=t$, $z=-8\cos t$, $0\leq t\leq \pi$\).

Formula to evaluate line integral:\($$\int_{C}f(x,y,z)ds = \int_{a}^{b}f(x(t),y(t),z(t))\sqrt{\left(\frac{dx}{dt}\right)^2+\left(\frac{dy}{dt}\right)^2+\left(\frac{dz}{dt}\right)^2} dt$$Here, $f(x,y,z) = xyz$, $x(t)=8\sin t$, $y(t)=t$, $z(t)=-8\cos t$, $a=0$, $b=\pi$.\)

Hence, we have\($$\begin{aligned}\int_{C}xyz ds &= \int_{0}^{\pi} (8\sin t)(t)(-8\cos t)\sqrt{\left(\frac{dx}{dt}\right)^2+\left(\frac{dy}{dt}\right)^2+\left(\frac{dz}{dt}\right)^2} dt \\ &= \int_{0}^{\pi} (-64\sin t\cos t)(t)\sqrt{(8\cos t)^2+1^2+(-8\sin t)^2} dt \\ &= -64\int_{0}^{\pi} t\sin t\cos t\sqrt{64\cos^2t+64\sin^2t+1} dt\end{aligned}$$Let $u=64\cos^2t+64\sin^2t+1=65$, $du = 0$. When $t=0$, $u=65$, and when $t=\pi$, $u=65$\)

Hence, we have\($$\begin{aligned}& \int_{C}xyz ds = -64\int_{0}^{65} \left(\frac{t}{2}\right)\sqrt{u}\left(\frac{du}{32}\right) \\ &= -2\int_{0}^{65} t\sqrt{u}\ du \\ &= -2\left[\frac{2}{5}u^{\frac{5}{2}}\right]_{0}^{65} \\ &= -\frac{2}{5}(65)^{\frac{5}{2}} \\ &= -\frac{2}{5}(65)(65)^2 \\ &= \boxed{-84550}\end{aligned}$$\)

The volume of a rectangular prism with a base length of 4 cm, a base width of 2 cm, and a height of 6 cm is 48 cubic cm. If we triple the size of the prism, then the new base length would be 12 cm, the new base width would be 6 cm, and the new height would be 18 cm. Therefore, the volume of the new prism would be:

Volume = (12 cm) x (6 cm) x (18 cm) = 1296 cubic cm

So the volume of the prism would be increased to 1296 cubic cm by tripling the size of the original prism.

To find the volume of a rectangular prism, we simply need to multiply the length, width, and height of the prism together. In this case, we were given the dimensions of the original rectangular prism and asked to find the volume of the new prism if we tripled its size. To do this, we simply multiplied each dimension by 3 to get the new dimensions and then calculated the new volume by multiplying those dimensions together.

The accumulated value of $8600 at 6.45% after 8 months (simple interest) is $8971.90.

To compute the accumulated value of $8600at 6.45% after 8 months (simple interest), we need to use the formula for simple interest, which is given by:

I = P × r × t

Where, I is the interest earned, P is the principal amount, r is the interest rate, and t is the time in years.

Here, we have t in months, so we need to convert it into years by dividing by 12.

So, t = 8/12 = 2/3 years.

Now, substituting the given values, we get:

I = 8600 × 6.45/100 × 2/3 = $371.90

Therefore, the accumulated value of $8600 at 6.45% after 8 months (simple interest) is $8600 + $371.90 = $8971.90.

Answer:

x=2

Step-by-step explanation:

We must equate f(x)=g(x) ;

x+3=2x^2-3

2x^2-x-6=0, when we solve for x in this equation we get 2 solutions:

x=2, x=-1.5

Since -1.5 is not seen in the table, we consider the value 2.

At x=2 in the table both f(x) and g(x) have the same value 5 and proves f(x)=g(x) has a solution at x=2.

Answer:

x = 2

Given:

f(x) = |x| + 3

g(x) = 2x² - 3

From inspection of the table, the equation f(x) = g(x) has a solution when

x = 2 as this is the only value of x when the two functions have the same value of 5.

The coordinates of the point at 3/4 of the distance from A to B from A is (-3.5, 1.25)

The coordinates of point A = (-5, -4),

The coordinates of the point B = (-3, 3)

Let the point at the distance 3/4 from A to B = P

The coordinates of point 3/4 from A to B = P

At the x-coordinate, the distance from B to A is =  -3-(-5) = 2 units.

At the y-coordinate, the distance from B to A is = 3-(-4) = 7 units.

Hence, the coordinates of P = (-5 + (3/4×(x-coordinate), -4 + 3/4×(y-coordinate)

                                            P = (-5 + (3/4×(2), -4 + 3/4×(7))

\(Rate = 20\)

So, the total savings is:

\(m = 200 + 20j\)

Ryan

\(Initial\ Savings = 350\)

\(Rate = 15\)

So, the total savings is:

\(r = 350 + 15j\)

To get the number of jobs they save the same amount.

We have:

\(m = r\)

Substitute values for m and r

\(200+20j = 350+15j\)

The standard deviation for this sample data set is 1.93.

What is deviation ?

Deviation refers to the difference between an individual value or observation and the average or mean value of a set of data. It can also refer to the extent to which a variable or set of data deviates from a standard or expected value.

To calculate the standard deviation for a sample data set, we first need to find the mean (average) of the data. In this case, the mean of the data set {5, 7, 6, 9, 6, 4, 4, 6, 5, 2, 5} is 5.45.

Once we have the mean, we can calculate the variance by taking the average of the squared differences between each data point and the mean. The variance is given by:

(1/n) * Σ(x_i - mean)^2

where n is the number of data points and x_i is the i-th data point.

The variance for this data set is 3.70.

Finally, we take the square root of the variance to get the standard deviation.

So, the standard deviation for this sample data set is 1.93.

The two theoretical quantities of ANOVA (Analysis of Variance) are:
1. Between-group variance.

2. Within-group variance:

1. Between-group variance.

This is the variance that can be attributed to differences between the group means.

It is calculated by comparing the mean of each group to the overall mean of all the data points.

The larger the between-group variance, the more likely there are significant differences between the groups.
2. Within-group variance:

This is the variance that can be attributed to differences within each group, i.e., the individual differences among the data points in each group.

It is calculated by comparing the individual data points in each group to their respective group mean.

The smaller the within-group variance, the more likely the groups are homogeneous.
In ANOVA, these two quantities are compared using an F-ratio.

If the between-group variance is significantly larger than the within-group variance, it indicates that there are significant differences between the group means, and the null hypothesis can be rejected.

Step-by-step explanation:

Given that b= [Question 13, 1.5.1].

To find the parametric equation of the line through a parallel to b, using t as the parameter, we follow the below steps.

Step 1: Write the equation of a as, a = (x1, y1, z1)

Step 2: Since line a is parallel to b, the direction ratios of a and b are equal. Hence the equation of the line parallel to b and passing through a can be written as r = a + λb where λ is a parameter.

Step 3: Substituting the values of a and b in the above equation, we get r = (x1, y1, z1) + λ[Question 13, 1.5.1].

Therefore, the parametric equation of the line through a parallel to b, using t as the parameter is r = (x1 + 4t, y1 - 2t, z1 + 2t) where λ = t.

=======================================================

Explanation:

The angles SPT and TPU marked in red are congruent. They are congruent because of the similar arc markings.

Those angles add to the other angles to form a full 360 degree circle.

Let x be the measure of angle SPT and angle TPU.

86 + 154 + 60 + x + x = 360

300 + 2x = 360

2x = 360-300

2x = 60

x = 60/2

x = 30

Each red angle is 30 degrees.

Then,

angle SPQ = (angle SPT) + (angle TPU) + (angle UPQ)

angle SPQ = (30) + (30) + (86)

angle SPQ = 146 degrees

--------------

Another approach:

Notice that angles QPR and RPS add to 154+60 = 214 degrees, which is the piece just next to angle SPQ. Subtract from 360 to get:

360 - 214 = 146 degrees
