Step-by-step explanation:

8.7 R is an improper  FRACTION of the 2 pi R of the entire circle ....set up a ratio:

8.7 / (2 pi)  =  3.9 / x       where x is the entire circumference measurement

x = 3.9 / (8.7 / (2 pi) )   = 2.82 units

Step-by-step explanation:

Since, the school club wants to collect at least 500 canned goods, then we know that they don't want to collect any less: they must collet 500 or more canned goods.

They already collected 30 canned goods, therefore we can subtract this quantity from out goal.

500 - 30 = 470

Since there are 10 club members, the number of members multiplied by "n" the minimum amount of canned goods that they can collect, will equal the total amount of canned goods that they need.

Answer:

LAST TABLLEE

Step-by-step explanation:

We are given a equation m²-10m+16

We have to find which diagram represents the factor of m²-10m+16 we will use splitting the middle term method:  

m²-10m+16 can also be written as

m²-8m-2m+16

= m(m-8)-2(m-8)

=(m-2)(m-8)

so, Last Table represents the factors of m²-10m+16

Option (B) Since y₁ = (__)y₂ on (0,1), the functions are linearly dependent on (0,1). (Simplify your answer.) is the correct answer

We have two functions which are y₁ = sin(t)cos(t)y₂ = 6sin(2t)

We need to determine whether the given functions are linearly dependent or linearly independent on the interval (0, 1).

To check whether y₁ and y₂ are linearly dependent or not, we must check if one of them can be represented as a linear combination of the other:

That is, we need to check whether there exist constants a and b, not both zero, such that: a y₁ + b y₂ = 0

On substituting the given values, we get: asin(t)cos(t) + b6sin(2t) = 0

We need to show that there exists non-zero values for 'a' and 'b' such that the above equation holds true. So we need to manipulate the above equation and try to solve for a variable.

6sin(2t) = -asin(t)cos(t)/b ⇒ 6sin(2t)/sin(t)cos(t) = -a/b

We can use the identity sin(2θ) = 2 sin(θ)cos(θ) to rewrite the left-hand side of the equation above:6sin(2t)/sin(t)cos(t) = 6(2sin(t)cos(t))/(sin(t)cos(t)) = 12

So, we have:12 = -a/b

Therefore, we can say that there exist non-zero values of 'a' and 'b' such that the linear combination a y₁ + b y₂ = 0. Thus, the given functions are linearly dependent on the interval (0, 1).Option (B) Since y₁ = (__)y₂ on (0,1), the functions are linearly dependent on (0,1). (Simplify your answer.) is the correct answer.

The value of the line integral is 2sqrt(14) - 5.

To evaluate the line integral, we need a vector function r(t) that traces out the curve C as t goes from a to b.

We can find a vector function r(t) for the line segment from (3, 3, 2) to (1, 2, 5) as follows:

r(t) = <3, 3, 2> + t<-2, -1, 3> for 0 ≤ t ≤ 1

We can then compute the differential ds as:

ds = |r'(t)| dt = sqrt(14) dt

Substituting y = 3-t, z = 2+3t, and ds = sqrt(14) dt in the given line integral:

∫C (-y)dx + xdy + zds

= ∫[0,1] [(3-t)(-2dt) + (3+3t)(-dt) + (2+3t)(sqrt(14) dt)]

= ∫[0,1] [-2t - 3 + 3t - sqrt(14)t + 2sqrt(14) + 3sqrt(14)t] dt

= ∫[0,1] [(6sqrt(14) - 2 - sqrt(14))t - 3] dt

= [(6sqrt(14) - 2 - sqrt(14))(1/2) - 3(1-0)]

= 2sqrt(14) - 5

Therefore, the value of the line integral is 2sqrt(14) - 5.

The abscissa on the curve x^2 = 2y which is nearest to the point (4,1) is x = √(3/8).

Given the equation x^2 = 2y.

The coordinates of the point are (4,1).We have to find the abscissa on the curve that is nearest to this point.So, let's solve this question:

To find the abscissa on the curve x2 = 2y which is nearest to the point (4,1), we need to apply the distance formula.In terms of x, the formula for the distance between a point on the curve and (4,1) can be written as:√[(x - 4)^2 + (y - 1)^2]But since x^2 = 2y, we can substitute 2x^2 for y:√[(x - 4)^2 + (2x^2 - 1)^2].

Now we need to find the value of x that will minimize this expression.

We can do this by finding the critical point of the function: f(x) = √[(x - 4)^2 + (2x^2 - 1)^2]To do this, we take the derivative of f(x) and set it equal to zero: f '(x) = (x - 4) / √[(x - 4)^2 + (2x^2 - 1)^2] + 4x(2x^2 - 1) / √[(x - 4)^2 + (2x^2 - 1)^2] = 0.

Now we can solve for x by simplifying this equation: (x - 4) + 4x(2x^2 - 1) = 0x - 4 + 8x^3 - 4x = 0x (8x^2 - 3) = 4x = √(3/8)The abscissa on the curve x^2 = 2y that is nearest to the point (4,1) is x = √(3/8).T

he main answer is that the abscissa on the curve x^2 = 2y which is nearest to the point (4,1) is x = √(3/8).

The abscissa on the curve x^2 = 2y which is nearest to the point (4,1) is x = √(3/8).

Explanation:

We can use subtraction and addition of integers to get the value of the given expression. We can write the given expression as;

-3 - 7 = -10 (-3 - 7)

The addition of two negative integers will always give a negative integer. When we subtract a larger negative integer from a smaller negative integer, we will get a negative integer.

If we add -3 and -7 we will get -10. This makes the option b the correct answer.

Part A:
To find f(3,1), we simply substitute x = 3 and y = 1 into the function f(x,y) = 5x^3y^3 + 9x.

f(3,1) = 5(3)^3(1)^3 + 9(3) = 135 + 27 = 162.

Therefore, f(3,1) = 162.

Part B:
To find the percent change in the function f(x,y) = 1.3^(x/y) from (5,1) to (8,4), we need to use the formula for percent change:

Percent Change = (New Value - Old Value)/Old Value x 100%

Let's first find the value of f(5,1) and f(8,4) using the given function:

f(5,1) = 1.3^(5/1) = 7.211
f(8,4) = 1.3^(8/4) = 4.746

Now we can substitute these values into the formula for percent change:

Percent Change = (4.746 - 7.211)/7.211 x 100%
Percent Change = -34.21%

Therefore, the percent change in the function f(x,y) = 1.3^(x/y) from (5,1) to (8,4) is -34.21%.

The correlation coefficient between the x and y scores is -2.167.

I will use the provided scores to answer questions 2a and 2b.

2a) Calculate the mean of the x scores.

To calculate the mean of the x scores, we add up all the x scores and divide by the total number of scores:

mean = (1 + 4 + 1 + 1 + 3)/5 = 2

Therefore, the mean of the x scores is 2.

2b) Calculate the correlation coefficient between the x and y scores.

To calculate the correlation coefficient between the x and y scores, we first need to calculate the covariance between the x and y scores:

cov(x,y) = (1-2)(6-2) + (4-2)(1-2) + (1-2)(4-2) + (1-2)(3-2) + (3-2)*(1-2) = -10

Next, we need to calculate the standard deviations of the x and y scores:

s_x = sqrt([(1-2)^2 + (4-2)^2 + (1-2)^2 + (1-2)^2 + (3-2)^2]/4) = 1.247

s_y = sqrt([(6-2)^2 + (1-2)^2 + (4-2)^2 + (3-2)^2]/4) = 2.309

Finally, we can calculate the correlation coefficient:

r = cov(x,y)/(s_x * s_y) = -10/(1.247 * 2.309) = -2.167 (rounded to three decimal places)

Therefore, the correlation coefficient between the x and y scores is -2.167.

To calculate the present value of Ahmed's payments, we need to discount each annual payment back to the present using the appropriate discount rate. In this case, the discount rate is the interest rate of 8%. The formula to calculate the present value of an annuity is:

PV = Payment × [(1 - \((1 + r)^{(-n)\)) / r],

where PV is the present value, Payment is the annual payment, r is the interest rate, and n is the number of periods.

Plugging in the values from the given information:

Payment = BD 5700

Interest rate (r) = 8% or 0.08

Number of periods (n) = 12

Using the formula, we can calculate the present value:

PV = BD 5700 × [(1 - \((1 + 0.08)^{(-12)\)) / 0.08]
