Answer:

one point five hundred sixteen thousandths

Step-by-step explanation:

Answer:

D: 5(9a-2b)

Step-by-step explanation:

Each expression in the choices is factored, so we need to see how to factor the given expression.

To factor the given expression, you need to factor out the greatest common factor of both terms.

The terms are 45a and -10b.

The GCF of 45 and -10 is 5.

The GCF of a and b is 1. There is no common factor other than 1.

The GCF of the 2 terms is 5, so we factor out a 5.

45a - 10b = 5(9a - 2b)

Answer: D: 5(9a-2b)

Answer:

C.

Step-by-step explanation:

So we have the equation:

\(y=\sqrt{x-3}\)

This is a square root equation.

For square root equations, the radicand(s) must be positive.

Therefore, to find the domain, set the radicand to be greater than or equal to 0:

\(x-3\geq 0\)

Solve for x. Add 3 to both sides:

\(x\geq 3\)

Therefore, our domain must be greater than or equal to 3.

In set notation, this is:

\(\{x:x\geq 3\}\)

Therefore, our answer is C.

All we need to do is solve for the 0 of the function.

Solution:

0 = √x-3

0^2 = x - 3

0 = x - 3

3 = x

The domain is greater than or equal to 3 and this can be written as x ≥ 3 or in other words, Option 3.

Best of Luck!

Answer:

Answer:

x=-16

y=40

Step-by-step explanation:

y=-4x-24

y+2x=8

its the same y. Use substitution

(-4x-24)+2x=8

-2x-24=8

-2x=32

x=-16

We found x!

substitute x in either equation

y+2x=8

y+2(-16)=8

y-32=8

y=40

Answer: (-16, 40)

Step-by-step explanation: Using substitution, you can but the first y=-4x-24 into the second equation y+2x=8. So, you take what y is (which is -4x-24) and substitute it for the second y in the equation y+2x=8.

Your equation should now look like this (-4x-24) + 2x = 8.

You can then solve -4x -24 +2x =8. Combine like-terms (-4x+2x) to get -2x-24=8. Then use inverse operations and add 24 from both sides (so from the -2x-24 side and 8 side). This will then give you -2x=32. divide both sides from -2x to get:

x = -16

Then, plug in x= -16 into the first equation (y= -4 (-16) - 24). Then use PEMDAS and multiply -4 and -16 to get +64. Subtract 24 to get:

y = 40

Using probability the correct option is B)The probability that p is in the interval is equal to the level of confidence for the interval.

What is probability?

Probability is a way to gauge how likely something is to happen. Many things are difficult to forecast with absolute confidence. Using it, we can only make predictions about the likelihood of an event happening, or how likely it is. Probability can range from 0 to 1, with 0 denoting an impossibility and 1 denoting a certainty. For pupils in Class 10, probability is a crucial subject because it teaches all the fundamental ideas of the subject. One is the probability of every event in a sample space.

The probability that p is in the interval is equal to the level of confidence for the interval.

Reason -

There is a 95% probability that the interval between X [lower bound] and Y [upper bound] contains the true value of the population parameter. The statement above is the most common misconception about confidence interval. After the statistical interval is calculated, the interval can only either contain the population parameter or not.

Hence the correct option is B) The probability that p is in the interval is equal to the level of confidence for the interval.

If circle with center N with m∠MNP=124 ∘ and MN=13,  the area of sector MNP is approximately equal to 194.86 square units.

To find the area of a sector of a circle, we need to use the formula:

Area of sector = (central angle/360°) x πr²

Where r is the radius of the circle.

In this problem, we know that the central angle m∠MNP is 124° and MN, which is also the radius of the circle, is 13. So we can substitute these values into the formula:

Area of sector = (124/360) x π(13)²

Area of sector ≈ 194.86

Therefore, the area of sector MNP is approximately equal to 194.86 square units.

Choice D is correct

Every point on circle is equidistant from the point at its centre and that fixed distance = radius of that circle.

The y-coordinate of center of mass is 1.2819 kg.

The center of mass, also known as the center of gravity, is a point in a system of objects where the total mass of the objects is concentrated. It represents the balance point of the system and is the point at which the system would balance if it were suspended from that point. The position of the center of mass is dependent on the distribution of mass in the objects making up the system.

The centre of mass of region R is given by

\($\mathrm{\bar{y}=\frac{\int_{R}\rho y_{e}dA}{Mass_{regionR}} \ \ where \ y_{e} \ center \ of \ mass \ of \ element}\)

For the vertical element,

\(\mathrm{y_{e}=\dfrac{y}{2}}\)

Find the numerator of the y coordinate of Center of Mass

\($\mathrm{\frac{1}{2}\int_{R}\rho yydx=\frac{\rho}{2} \int_{\frac{-\pi}{3}}^{\frac{\pi}{3}} (3cosx)^2dx=\frac{9\rho}{2} \int_{\frac{-\pi}{3}}^{\frac{\pi}{3}} cos^2xdx=\frac{9\rho}{2} \int_{\frac{-\pi}{3}}^{\frac{\pi}{3}} (\frac{1+cos(2x)}{2})dx}\)

\($\mathrn{\frac{9\rho}{4} \int_{\frac{-\pi}{3}}^{\frac{\pi}{3}} (1+cos(2x))dx=\frac{9\rho}{4} [x+\frac{sin(2x)}{2}]_{\frac{-\pi}{3}}^{\frac{\pi}{3}}}\)

\($\mathrm{\frac{9\rho}{4} \left[\frac{\pi}{3}+\frac{sin(2(\frac{\pi}{3}))}{2}\right ]-\frac{9\rho}{4} \left[\frac{-\pi}{3}+\frac{sin(2(\frac{-\pi}{3}))}{2}\right ]}\)

\($\mathrn{\frac{9\rho}{4} \left[\frac{\pi}{3}+\frac{\sqrt{3}}{4}\right ]-\frac{9\rho}{4} \left[\frac{-\pi}{3}-\frac{\sqrt{3}}{4}\right ]=\frac{9\rho }{4} \left[\frac{2\pi}{3}+\frac{\sqrt{3}}{2}\right ]}\)

Therefore, the y-coordinate of center of mass is

\($\mathrm{\bar{y}=\frac{\dfrac{9\rho }{4}\left [\dfrac{2\pi}{3}+\dfrac{\sqrt{3}}{2}\right ]}{3\rho \sqrt{3}}=\frac{\sqrt{3}}{4}\left [\frac{2\pi}{3}+\frac{\sqrt{3}}{2}\right ]=\frac{3}{8}+\frac{\sqrt{3}\pi}{6}=1.2819}\)

Thus, The y-coordinate of center of mass is 1.2819 kg

The center of mass of a thin plate of constant density is determined by its area and the distribution of its mass.

To find the center of mass of this plate, we first need to calculate its area. We can do this by using the formula for the area of a region bounded by the x-axis and a curve y=f(x):

A = ∫\(a^{b}\) ydx = ∫-pi/3^pi/3 3cosx dx

A = 3∫-pi/3^pi/3cosx dx

A = 3(sin(pi/3) - sin(-pi/3))

A = 3(sin(pi/3) + sin(pi/3))

A = 6sin(pi/3)

A = 6*(1/2)

A = 3

Now that we know the area of the plate, we can calculate its center of mass. To do this, we need to use the formula for the center of mass of a region bounded by the x-axis and a curve y=f(x):

xcm = 1/A ∫\(a^{b}\) xydx

xcm = 1/3 ∫-pi/3^pi/3 x(3cosx) dx

xcm = 1/3 ∫-pi/3^pi/3 3xcosx dx

xcm = 1/3(3(sin(pi/3) - sin(-pi/3)) - 3xsin(pi/3) + 3xsin(-pi/3))

xcm = 1/3(6sin(pi/3) - 3pi/3sin(pi/3) + 3(-pi/3)sin(-pi/3))

xcm = 1/3(6sin(pi/3) - 3pi/3sin(pi/3) + 3pi/3sin(pi/3))

xcm = 0

Therefore, the center of mass of the plate is located at (0, 0).

Answer: (x,y) → (2x,2y) .

Step-by-step explanation:

If we transform point (x,y) by using dilation with scale factor k (assume center of dilation at (0,0) then the coordinate of the image will be (kx,ky).

So, the coordinate expression represents the coordinates of any point after dilation by a scale factor of 2:

(x,y) → (2x,2y) .

Answer:

When figure ABCD is dilated by a scale factor of 2, the coordinates of all the points in the dilated figure are multiplied by 2.

\(2\frac{2}{3} + 3\frac{1}{3} + 1\frac{2}{3} = 7\frac{2}{3} \)

let's convert each mixed fraction into improper fractions. Therefore,

Improper fractions are fractions that has the numerator bigger than the denominator.

\(2\frac{2}{3} = \frac{8}{3} \)

\(3\frac{1}{3} = \frac{10}{3} \)

\(1\frac{2}{3} = \frac{5}{3} \)

Therefore,

\(\frac{8}{3} + \frac{10}{3} + \frac{5}{3} \)

\( \frac{8}{3} + \frac{10}{3} + \frac{5}{3} = \frac{8 + 10 + 5}{3} = \frac{23}{3} \)

Step-by-step explanation:

:)

\(x=2y\) and \(x=y^3\) intersect when

\(2y=y^3\implies y^3-2y=y(y^2-2)=y(y-\sqrt2)(y+\sqrt2)=0\)

\(\implies y=0\text{ or }y=\sqrt2\text{ or }y=-\sqrt2\)

We omit the negative root, since we only care for \(y\ge0\).

In the interval (0, √2), we have \(y^3<2y\). Then the volume is given by the integral

\(\displaystyle\pi\int_0^{\sqrt2}(2y)^2-(y^3)^2\,\mathrm dy=\pi\int_0^{\sqrt2}4y^2-y^6\,\mathrm dy\)

and so the volume is (32√2)/21 π.

Answer:

B.     70.2 mm³

Step-by-step explanation:

The solid figure shown is a triangular prism of dimensions 3 x 9.7 x 7.2

The volume of a triangular prism as shown is half the volume of a rectangular prism of the same dimensions

Volume of a rectangular prism = h x l  x w

Volume of a triangular prism = h x l x w/2

where h = height of the prism
l, w are the dimensions of the base

we are given
l = 7.2 and w = 3 both in mm

We have to calculate the height
The diagonal of the prism (9.7 mm) and the length of the base(7.2 mm) form a right triangle with the height h as the other side of the triangle

We can use the Pythagorean theorem to compute h

9.7² = 7.2² + h²

h² = 9.7² - 7.2²
    =  42.25 mm²

h = √42.25 = 6.5 mm

So volume of the triangular prism
= (3 x 6.5 x 7.2 )/2

= 140.4/2

= 70.2 mm³
