What is 4/16 in simplest form

Answer: A

Step-by-step explanation:

The percentage of students with more than 1 brother or sister is 41%.

To find the percentage, first complete the table:

118 - 62 = 56 female students with 1 brother and sister.
8 + 14 = 22 7th years with 3 brothers and sisters.
118 + x + 22 + 6 = 200, x = 200 - 146, x = 54 7th years with 2 brothers and sisters.
54 - 24 = 30 male students with 2 brothers and sisters.
62 + 30 + 8 + y = 104, y = 104 - 100, y = 4 male students with 4 brothers and sisters.
6 - 4 = 2 female students with 4 brothers and sisters.
56 + 24 + 14 + 2 = 96 total female students of 7th year.

The percentage of students with more than i brother and sister is:

54 + 22 + 6 = 82 students or 200 - 118 = 82 students.

% = 82 / 200 x 100 = 41%.

Answer: the third option

Step-by-step explanation:

Option B. 2 K is the correct graph (check the attached image) of parent function after transformation.

In mathematics, a transformation is a function that, typically with some geometrical foundation, maps a set X to itself, i. e. f: X → X. Vector space linear transformations are one example.

A point, line, or geometric figure can be changed in four different ways that are all collectively referred to as transformations. Pre-Image refers to the object's initial shape, and Image, after transformation, refers to the object's final shape and location.

A graph can be altered in three basic ways: by shifting, or compressing, and by flipping. According to the definition of transformation, we can rotate around any point, reflect our image over any line, and translate any vector. These are rigid transformations in which the image is consistent with its pre-image.

The value of V = 2π/3. To find the volume of the solid, we need to use the method of cylindrical shells.

First, we need to solve for the x and y intercepts of the curve. Setting x = 0 gives y = 0, and setting y = 0 gives x = ±1. So the curve intersects the x-axis at (-1, 0) and (1, 0).

Next, we need to find the height of each cylindrical shell. The height is given by the difference between the y-values of the curve and the line x = 1. Solving for y in 2xy = 1 + x^2, we get y = (1 + x^2)/(2x). So the height of the cylindrical shell at x is given by (1 + x^2)/(2x).

Finally, we need to find the radius of each cylindrical shell. The radius is simply x.

So the volume of the solid is given by the integral from x = 0 to x = 1 of 2πx(1 + x^2)/(2x) dx. Simplifying and integrating, we get V = 2π/3.

Answer: a) The set W contains the zero vector, since (0,0,0) = (3s,-2s,s) for s = 0.

The set W is closed under addition and scalar multiplication:

If (3s1, -2s1, s1) and (3s2, -2s2, s2) are in W, then their sum, (3(s1 + s2), -2(s1 + s2), (s1 + s2)), is also in W.

If (3s, -2s, s) is in W and c is any scalar, then (3cs, -2cs, cs) is also in W.

The set W has a basis of {(3, -2, 1)}. To see this, we can write any vector in W as a scalar multiple of (3, -2, 1). For example, (3s, -2s, s) = s(3, -2, 1). The dimension of the set W is 1.

b) The set W contains the zero vector, since (t-2,0,6-3t) = (t-2,0,6-3t) for t = 2.

The set W is closed under addition and scalar multiplication:

If (t1 - 2, 0, 6 - 3t1) and (t2 - 2, 0, 6 - 3t2) are in W, then their sum, ((t1 + t2) - 2, 0, 6 - 3(t1 + t2)), is also in W.

If (t - 2, 0, 6 - 3t) is in W and c is any scalar, then (ct - 2c, 0, 6c - 3ct) is also in W.

The set W has a basis of {(1, 0, -3)}. To see this, we can write any vector in W as a scalar multiple of (1, 0, -3). For example, (t - 2, 0, 6 - 3t) = t(1, 0, -3) - 2(1, 0, -3). The dimension of the set W is 1.

c) The set H contains the zero vector, since (2b, a, 3b) = (0,0,0) for b = 0 and a = 0.

The set H is closed under addition and scalar multiplication:

If (2b1, a1, 3b1) and (2b2, a2, 3b2) are in H, then their sum, (2(b1 + b2), a1 + a2, 3(b1 + b2)), is also in H.

If (2b, a, 3b) is in H and c is any scalar, then (2cb, ca, 3cb) is also in H.

The set H has a basis of {(2,1,3)}. To see this, we can write any vector in H as a scalar multiple of (2,1,3). For example, (2b, a, 3b) = b(2,1,3) + a(0,1,0). The dimension of the set H is 2.

d) The set H contains the zero vector, since (−b + 2c, b, 4c) = (0,0,0) for b = 2c.

The surface area Sam needs to paint on the cylinder is  πx² + 2πxy i.e. B.

What exactly is a cylinder?

In geometry, a cylinder is one of the fundamental 3d forms with two parallel circular bases at a distance. A curving surface connects the two circular bases at a predetermined distance from the centre. The axis of the cylinder is the line segment connecting the centres of two circular bases. The height of the cylinder is defined as the distance between the two circular bases. One real-world example of a cylinder is an LPG gas-cylinder.

Because the cylinder is a three-dimensional form, it has two primary properties: surface area and volume. The cylinder's total surface area (TSA) is equal to the sum of its curved surface area and the area of its two circular bases.

The volume of a three-dimensional cylinder is the space it occupies (V).

TSA=2πr²+2πrh, where r is the radius and h is the height.

Now,

Given that the radius of the roof is x feet and the silo is y feet high

Area of roof=πx² and

curved surface area=2πxy

then the surface area Sam needs to paint=πx²+2πxy

Hence,

        The surface area Sam needs to paint on the cylinder is

πx² + 2πxy.

Answer: 9.43398113206

Step-by-step explanation:

A^2 + B^2 = C^2

5^2 + 8^2 = √89

= 9.43398113206

(a) P = [tex](56035e^(0.3283t)) / (560 + 35(e^(0.3283t)-1))[/tex] (b) 345 panthers (c) 1.59 years (d) dP/dt = kP(1 - P/560), P(5) ≈ 373 panthers (e) 1.59 years.

(a) The logistic equation that models the population of panthers in the preserve is:

P = [tex](560P0e^{(kt)}) / (560 + P0(e^{(kt)-1}))[/tex]

where P0 is the initial population (35), k is the growth rate constant, and t is the time in years.

To solve for k, we can use the fact that after 2 years the population is 200:

200 =[tex](56035e^(2k)) / (560 + 35(e^{(2k)-1}))[/tex]

Solving for k, we get:

k = 0.3283 (rounded to 4 decimal places)

Therefore, the logistic equation is:

P = (56035e^(0.3283t)) / (560 + 35(e^(0.3283t)-1))

(b) To find the population after 5 years, we substitute t=5 into the logistic equation:

P = (56035e^(0.32835)) / (560 + 35(e^(0.32835)-1))

P ≈ 345 panthers (rounded to the nearest whole number)

(c) To find when the population reaches 280, we can solve the logistic equation for t when P=280:

280 = [tex](56035e^{(0.3283t)}) / (560 + 35(e^{(0.3283t)-1}))[/tex]

Solving for t, we get:

t ≈ 1.59 years (rounded to 2 decimal places)

(d) The logistic differential equation that models the growth rate of the panther population is:

dP/dt = kP(1 - P/560)

Using Euler's method with a step size of h=1, we get:

P(5) ≈ P(4) + hdP/dt(4)

P(4) = 345 (from part b)

dP/dt(4) = k345*(1 - 345/560) = 27.522

P(5) ≈ 345 + 27.522 = 373 panthers (rounded to the nearest whole number)

(e) The panther population is growing most rapidly when the growth rate is at its maximum, which occurs at half the carrying capacity (P=280). We can find the time by taking the derivative of the logistic equation and setting it equal to zero:

dP/dt = kP(1 - P/560)

0 = k280(1 - 280/560)

0.5 = 1 - 280/560

280 = 560/2

So, the panther population is growing most rapidly when P=280, which occurs at half the carrying capacity. Therefore, the time when the population is growing most rapidly is at t=1.59 years (from part c).

Answer:

y = -1/4x + 2

Step-by-step explanation:

First you have to pick 2 points on the line, then you find the slope of the line from those 2 points. The slope formula is m = (y2-y1) / (x2-x1), and filling the variables in with the points (0,2) and (4,1) gives you m = (1-2) / (4-0), which gives you m = -1/4.

Once you have found the slope, you look for the y-intercept which is the point where the x-value is 0, and that is 2 in this graph.

You can then put this information into slope-intercept form, y= mx + b. m represents the slope and b represents the y-intercept. The answer is y = -1/4x + 2
