Answer:A number is divisible by 2 if it ends in 2, 4, 6, 8 or 0. A number is divisible by 5 if it ends in 5 or 0. A number is divisible by 10 if it ends in a 0.Apr 8, 2018

The function is constant in the interval (-6 to 0).

The correct option is (C).

In mathematics, a function is represented as a rule that produces a distinct result for each input x. In mathematics, a function is indicated by a mapping or transformation. The collection of all the values that the function may input while it is defined is known as the domain. The entire set of values that the function's output can produce is referred to as the range. The set of values that could be a function's outputs is known as the co-domain.

If the value of one of the variables does not alter the value of the other, the function is said to be constant.

As we can see, the function is constant in the range from x=-6 to 0, because the value of y in the function does not change as the value of x changes (-6 to 0).

In the ΔWXY, with the incenter of the triangle being Z.

1. The measure of m∠WYZ = 43°.

2. The measure of m∠WXY = 66°.

3. The measure of m∠YWX = 28°.

4. The measure of m∠ZWX = 14°.

What is an incenter?

The intersection of the triangle's three interior angle bisectors forms the triangle's incenter. Due to the junction point of the central axis being the centre of the triangle's inscribed circle, this point is equally spaced from the sides of a triangle.

In ΔWXY, the incenter of the triangle is Z.

This means that ∠W, ∠Y and ∠X are equally bisected angles.

It is given that the measurement of ∠WYX = 86° and ∠WXZ = 33°

1. The measure of angle ∠WYZ.

The angle ∠WYX is bisected by the line segment YZ.

It forms two angles ∠WYZ and ∠XYZ.

So, the measurement of ∠WYZ = ∠WYX/2

∠WYZ = 86°/2

∠WYZ = 43°

Therefore, the measurement of ∠WYZ = 43°.

2. The measure of angle ∠WXY.

The angle ∠WXY is bisected by the line segment XZ.

It forms two angles ∠WXZ and ∠ZXY.

The measurement of angle ∠WXZ = 33°.

So,  the measurement of ∠WXY = ∠WXZ × 2

∠WXY = 33° × 2

∠WXY = 66°

Therefore, the measurement of ∠WXY = 66°.

3. The measure of angle ∠YWX.

According to the properties of the triangle, the sum of three angles of triangle is 180°.

So, the equation will be -

∠YWX + ∠WXY + ∠XYW = 180°

∠YWX + 66° + 86° = 180°

∠YWX + 152° = 180°

∠YWX = 180° - 152°

∠YWX = 28°

Therefore, the measurement of ∠YWX = 28°.

4. The measure of angle ∠ZWX.

The angle ∠YWX is bisected by the line segment WZ.

It forms two angles ∠YWZ and ∠ZWX.

So, the measurement of ∠ZWX = ∠YWX/2

∠ZWX = 28°/2

∠ZWX = 14°

Therefore, the measurement of ∠ZWX = 14°.

Answer:

x = bottles

y = pail

So, originally the pail had 3.68L from the finished bottle

x+3.68L=y

Then the second equation is after Bill spills 1.2L from the pail, the contents are 3 times that of the bottle

y-1.2L=3x

then played first

so

x-y = -3.68

-3x+y= 1,2

__________+

-2x= -2.48

x=1.24L

So the volume of the bottle is 1.24 L

Pail volume: 1.24+3.68= 4.92L

The radius of the cylinder with a combined volume of 1000 cubic inches is 2.4 inch

An equation consists of numbers and variables linked together by mathematical operations to form an expression.

Let r represent the radius of the cylinder/cone.

For the cylinder:

Volume = π * radius² * height

but height is twice the radius, height = 2r, hence:

Volume = π * r² * 2r = 2πr³

For the cube:

Volume = side³

but side is four times the radius, side = 4r, hence:

Volume = (4r)³ = 64r³

The combined volume of a cube and a cylinder is 1000 cubic inches, hence:

1000 = 2πr³ +  64r³

r³(2π + 64) = 1000

Answer: 49 Stamps

Step-by-step explanation:

If Lauren gave Kristen and Ethan 12 stamps and 15 stamps respectively, that means that she gave them a total of 27 stamps. This leaves her with 22 stamps left. In order to find the number of stamps she had at the start, add the stamps she gave away to the stamps she had left at the end. So,

15 stamps + 12 stamps + 22 stamps = 49 stamps total at the start

Lauren had 49 stamps in the beginning. Since she gives Kristen 12 stamps, and Ethan 15 stamps, we can add both amounts to assume the total number of stamps she gave away. 15+12=27, so she gave away 27 stamps.  Lauren was left with 22 stamps. We can add 22 to 27 to find out how many stamps she had in all. 27+22=49. Therefore, we can come to the conclusion that Lauren had 49 stamps at the start.

The amount of snow that falls from time t = 0 to time t = 5 hours is 20(1-e^(-0.5)) inches.

What is integration ?

Integration is the process of finding an antiderivative of a function. An antiderivative of a function is a function whose derivative is equal to the original function. In other words, integration is the reverse process of differentiation. The process of integration can be thought of as the summing of an infinite number of infinitesimal "slices" of the function being integrated, over a given interval. The symbol ∫ is used to denote integration.

The amount of snow that falls between time t = 0 and time t = 5 hours can be found by evaluating the definite integral of the rate of snowfall with respect to time over the interval [0, 5].

∫[0,5] 2e^(-0.1t) dt

The antiderivative of 2e^(-0.1t) with respect to t is -20e^(-0.1t)

Therefore, the definite integral is

-20e^(-0.15) - (-20e^(-0.10))

= -20e^(-0.5) + 20 = 20(1-e^(-0.5))

Therefore, the amount of snow that falls from time t = 0 to time t = 5 hours is 20(1-e^(-0.5)) inches.

What is the system of equations?

A set or group of equations that are solved collectively is referred to as a system of equations. Both algebraic and graphical solutions are possible for these equations. The point of intersection of two lines represents the system of equations' solution.

Line 1

Taking two points on this line (0,300) and (4,450)

Equation of line y = mx+c

m = [tex]\frac{450 - 300}{4 - 0}[/tex] = 37.5

y = 37.5x + c

Substituting (0,300) in the above equation

300 = 37.5 * 0 + c

c = 300

Line equation y = 37.5x + 300

Line 2

Taking two points on this line (0,400) and (5,500)

m = [tex]\frac{500 - 400}{5 - 0}[/tex] = 20

y = 20x + c

Substituting (0,400) in the above equation

400 = 250* 0 + c

c = 400

Line equation y = 20x + 400

The separation between endpoints A and B is the length of this line segment. An area or portion of a line with two endpoints is known as a line segment. A line segment has a set length as opposed to a line. Both metric measurements, such as millimeters and centimeters, as well as conventional units, such as feet or inches, can be used to measure the length of a line segment. The length of one line segment in comparison to the other when there are two can be determined just by glancing at them. The line segment CD is longer than AB, as can be seen.

Answer:

3.64 meters

Step-by-step explanation:

To find the height of the tree to the nearest hundredth of a meter, you can use the principle of similar triangles.

First, we can use the Pythagorean theorem to find the length of the hypotenuse of the right triangle formed by the height of the tree, the distance between the base of the tree and the point where the shadows meet, and the length of the shadow of the tree.

c = √(a² + b²)

c = √(h² + 26.2²)

Next, we can use the similar triangles to establish a ratio between the length of the shadow and the height of the tree and the length of the shadow and the distance from the tree.

shadow tree / height tree = shadow person / height person

31.55 / h = 31.55 / 26.2

Now, we can cross-multiply and divide to solve for h

h = 31.55 * 1.35 / 26.2

h = 3.64 meters

We can round it up to the nearest hundredth of a meter:

h = 3.64 meters

Therefore, the height of the tree is 3.64 meters to the nearest hundredth of a meter.
