Given:

In triangle XYZ, P is the centroid of triangle XYZ, YP = 8, QP = 5, YZ = 10.

To find:

The measure of median YS.

Solution:

We know that a centroid divides a median in 2:1.

P is the centroid and YS is the median. So,

\(YP:PS=2:1\)

Let the measure of YP and PS are 2x and x.

It is given that the measure of YP is 8.

\(2x=8\)

\(x=\dfrac{8}{2}\)

\(x=4\)

\(PS=4\)

Now, the measure of YS is:

\(YS=YP+PS\)

\(YS=8+4\)

\(YS=12\)

The measure of median YS is 12 units. Therefore, the correct option is (a).

Answer:

I hope this is right - y= 17x/7

Step-by-step explanation:

The smallest possible value of nullity(A) is 0, and the largest possible value of nullity(A) is 8.

The nullity of a matrix is the dimension of its null space, which represents the set of vectors that satisfy the equation A * x = 0, where A is the matrix and x is a vector.

The nullity of a matrix can range from 0 to the number of columns in the matrix. In this case, since A is a 3 x 8 matrix, the minimum possible value of nullity(A) is 0, indicating that the null space is trivial and contains only the zero vector. This occurs when the matrix is full rank, meaning that its columns are linearly independent.

On the other hand, the maximum possible value of nullity(A) is 8, which would occur if the matrix has rank 0. In this case, all the columns of the matrix are linearly dependent, and the null space spans the entire vector space of size 8.

Therefore, the smallest possible value of nullity(A) is 0, and the largest possible value of nullity(A) is 8.

Sherry needs to invest $2000 in a mutual fund that earns 1% interest a year and $13200 in a mutual fund that earns 4% interest a year.

According to the question,

We have the following information:

Amount to be invested = $15200

Interest earned 1% a year and 4% a year

Total amount interest to be earned at the end of first year = $548

Now, let's take the amount to be invested in 1% interest a year's mutual fund to be $x.

Then, we have the amount to be invested in mutual fund that earns 4% a year:

$(15200-x)

So, we have the following expression by removing percentage sign:

x/100 + (15200-x)4/100 = 548

Taking 100 as the least common factor and using the cross multiplication method:

x+60800-4x = 548*100

-3x = 54800-60800

-3x = -6000

x = 6000/3

x = $2000

Now, the amount invested in second mutual fund:

15200-2000

$13200

Hence, Sherry needs to invest $2000 in a mutual fund that earns 1% interest a year and $13200 in a mutual fund that earns 4% interest a year.

The shortest length of fence that the rancher can use is 6000 ft.

What is meant by length?

The measuring of one thing from finish to finish or on its longest aspect, or a measuring of a selected a part of one thing is known as length.

Main Body:

x = width of rectangle

y = length of rectangle

A = area of rectangle = xy = 1500000 ft^2

L = length of fencing needed = 2(x + y) + x = 3x + 2y

L = 3x + 2(1500000/x) = 3x + 3(10^6)x^(-1)

As x –> 0+, L –> +inf.

As x –> +inf, L –> (3x)+.

Sketch and see that there will be a minimum in Quadrant I.

dL/dx = 3 - 3(10^6)x^(-2)

Extrema occur when dL/dx = 0:

3 - 3(10^6)x^(-2) = 0

(10^6)x^(-2) = 1

x^2 = 10^6

x > 0, so x = 1000 feet for shortest length.

Hence,Shortest L = 3000 + 3(10^6)(10^3)^(-1) = 6000 feet.

a) The small tire would  make 38  rotations

   The large tire would make 127  rotations

b) A bicycle with two large wheels would allow traveling faster with each rotation of the pedal .

The problem we are dealing with relates to rotations and circumference where rotation refers to the distance from the center to any point on the shape that remains the same and whereas the circumference is the perimeter of a circle. In one revolution a wheel covers a distance which is rise to its perimeter.Since we are provided that the diameter of the large wheel is 60 inches, so the radius will be 30 inches ( radius = diameter/2) and the radius of the small wheel is 9 inches.

The circumference of a circle  is 2πr

for a large wheel  the circumference is 2 x 3.14 X 30 = 188.4 inches

for a small  wheel, the circumference is  56.52

Since, we know 1 inch is equal to 0.0833333, as the traveling distance = 600 feet = 7200 inches.

Number of rotation = distance / circumference

For large wheel = 7200 /188.4 =38.21 = spprox 38

For small wheel = 7200/56.52 =127.38 = approx 127

Since we bicycle with bigger wheels is preferable as they can go faster than the ones with little wheels since their circumference is more as they cover more area in fewer rotations.

The value of x in the right triangle is  4√2 units.

Similar triangles are the triangles that have corresponding sides in ratio to each other and corresponding angles congruent to each other.

Therefore, the triangles are similar. Let's use this similarity to find the value of x in the triangles.

Hence, using proportion,

x / 8 = 4 / x

cross multiply

x² = 8 × 4

x² = 32

square root both sides of the equation

x = √32

x = √16 × 2

When creating a confidence interval for the mean in a (B) t-distribution, the number of standard deviations needed is determined using the following distribution.

Any member of the family of continuous probability distributions known as the Student's t-distribution (or simply the t-distribution) in probability and statistics is used to estimate the mean of a normally distributed population when the sample size is small and the population's standard deviation is unknown.

The following distribution is used to calculate the number of standard deviations required for our confidence interval when doing a confidence interval for the mean in a t-distribution.

The Student's t-test for determining the statistical significance of the difference between two sample means, the construction of confidence intervals for the difference between two population means, and linear regression analysis are just a few commonly used statistical analyses that make use of the t-distribution.

Therefore, when creating a confidence interval for the mean in a (B) t-distribution, the number of standard deviations needed is determined using the following distribution.

Utilizando el teorema de Pitágoras, podemos calcular la altura que alcanza la escalera sobre la pared.

La fórmula sería: altura^2 = hipotenusa^2 - base^2. En este caso, la hipotenusa es la longitud de la escalera, que es de 15 metros, y la base es la distancia desde el pie de la escalera hasta la pared, que es de 9 metros. Sustituyendo estos valores en la fórmula, tenemos: altura^2 = 15^2 - 9^2. Resolviendo la ecuación, se obtiene: altura^2 = 144. Tomando la raíz cuadrada de ambos lados, obtenemos: altura = √144 = 12 metros.

Por lo tanto, la altura que alcanza la escalera sobre la pared es de 12 metros.

The center of the curve is c. Hyperbola; center (-5, -2). The correct option is:c.

The given equation is 9y² - 4x² - 36y - 82 = 0.

To identify the curve and find the center, we need to check the signs of the coefficients of x² and y². Here, x² has a negative coefficient and y² has a positive coefficient, which suggests that the given equation represents a hyperbola.

To find the center of the hyperbola, we need to rewrite the equation in the standard form, which is of the form:

[(y - k)² / a²] - [(x - h)² / b²] = 1

where (h, k) is the center of the hyperbola, a is the distance from the center to the vertices, and b is the distance from the center to the foci.

Rewriting the given equation in the standard form, we get:

9(y² + 4y) - 4(x² + 20x) = 328

Dividing both sides by 36, we get:

[(y + 2)² / 4²] - [(x + 5)² / (3/2)²] = 1

Comparing this equation with the standard form, we get:

Center = (-5, -2)

Therefore, the correct option is:

c. Hyperbola; center (-5, -2)

Answer:

To start off, this fraction needs to be rationalized; you can't have a radical in the denominator. So, you multiply both the numerator & denominator by the same number (so as to not mess up the proportion of numerator:denominator; it's like multiplying by 1) & get the radical out of the denominator. What number would that be? sqrt5.

So we have (sqrt6/sqrt5)•(sqrt5/sqrt5).

To simplify that, we get (sqrt6•sqrt5)/(sqrt5•sqrt5).

This can be rewritten as:

sqrt(6•5)/sqrt(5•5)

= sqrt30/sqrt25

Now, sqrt25 = 5, so that problem is solved as such:

sqrt30/5

I'm thinking sqrt30 can't be simplified any further. If it can, do so.
