The simplification of the expression −10x - 7x⁴ in the reduced factor form is equal to -1x ( 10 + 7x³ ).

The expression is equal to,

−10x - 7x⁴

From both the terms of the given expression '-1' is the common factor we get,

−10x - 7x⁴

= ( -1 ) ( 10x + 7x⁴ )

Now take variable 'x' common from both the terms of the expressions we get,

A function is a mathematical concept that describes a relationship between two sets of values, called the domain and the range. It is a rule or a set of rules that assigns a unique output value for every input value in the domain. In other words, it is a process that takes one or more inputs and produces a corresponding output. Functions are commonly represented using equations, graphs, or tables. They are used in various branches of mathematics, science, engineering, and technology to model real-world phenomena, make predictions, and solve problems.

Here,

To find the time at which the population is at a maximum, we need to find the time when the rate of change of population, or the derivative of p(t), is zero.

p(t) = -1715t² + 85,000t + 10,000

p'(t) = -3430t + 85,000

Setting p'(t) = 0, we get:

-3430t + 85,000 = 0

Solving for t, we get:

Rigid transformation refers to a type of geometric transformation that preserves the shape and size of an object. In other words, the transformed object is congruent to the original object.

Rigid transformations can be of two types -

Translation refers to moving an object in a straight line, while rotation refers to turning an object around a fixed point.

Rotation, in particular, has the effect of changing the orientation of the object. However, the length of each side and the angles between them will remain the same.

In a rigid transformation, the position of every point in the object is changed, but the distances between points remain unchanged, as well as the angles between lines and the area of the object.

If a triangle has a right angle (90 degrees), it is called a right triangle. The side opposite the right angle is called the hypotenuse, and it is the longest side of the triangle. The other two sides are called the legs.

To find the length of the third side of a right triangle, we can use the Pythagorean theorem, which states that in a right triangle, the sum of the squares of the two legs is equal to the square of the hypotenuse.

The Pythagorean theorem can be written as:

a^2 + b^2 = c^2

where a and b are the lengths of the two legs, and c is the length of the hypotenuse.

But you already know c, and with that c^2, you want to find a through a^2(you can also look for b, it would be the same)

If you rearrange the equasion you get a^2=c^2-b^

Once we have these lengths

c=15,so c^2 is 15^2=15*15=225

b=10,so b^2 is 10^2=10*10=100

we can plug them into the Pythagorean theorem and solve for the unknown side.

a^2=c^2-b^2

a^2=225-100=1125

The solution of the triangle is shown below;

Angle A - 26.98°

Angle C - 118.6°

Side c -  47.98

If you know the length of one side and the measure of the opposite angle, or the length of two sides and the measure of the angle between them, you can use the Law of Sines to find the other parts of the triangle.

Using the sine rule;

a/Sin A = b/Sin B

aSin B = bsinA

Sin A = bSinB/a

A = Sin-1( bSinB/a)

A = Sin-1(30.9 * Sin 34.42/38.5)

A = 26.98°

Then;

C = (180 - 26.98 + 34.42)

C = 118.6°

Using the sine rule again;

b/sinB = c/Sin C

c = bSin C/Sin B

c = 30.9 * Sin 118.6/Sin 34.42

c = 27.12/0.565

Find the complete question below.

The volume of a sphere whose diameter is 18 centimeters is 972π cubic centimeters. If its diameter were reduced by half, its volume would be 1/8 of its original volume. So, correct options are D for both blanks.

The diameter of a sphere is 18 cm, so its radius is half of the diameter, which is 9 cm. The formula for the volume of a sphere is (4/3)πr³, where r is the radius of the sphere.

Using this formula, we can calculate the volume of the sphere as follows:

V = (4/3)π(9³)

V = (4/3)π(729)

V = 972π cubic cm

Therefore, the volume of the sphere is 972π cubic cm.

Now, if the diameter of the sphere is reduced by half, the new diameter would be 9 cm, which means the new radius would be half of 9 cm, which is 4.5 cm. Using the same formula for the volume of a sphere, we can calculate the new volume of the sphere as follows:

V' = (4/3)π(4.5³)

V' = (4/3)π(91.125)

V' = 121.5π cubic cm

To find the ratio of the new volume to the original volume, we can divide the new volume by the original volume:

V'/V = (121.5π) / (972π) = 1/8

Therefore, the answer to the first part of the question is option (d) 972π cubic cm, and the answer to the second part of the question is option (d) 1/8.

For the original question, we know that each roll of ribbon is 9 feet long. To convert to inches, multiply 9 by 12.

9*12 = 108

Now, to find how many 18-inch pieces of ribbon there are in 108 inches,  divide 108 by 18.

Answer:

The glass cannot fit through the door.

Step-by-step explanation:

We can use the Pythagorean theorem to solve this problem. Let the height of the door be h.

We know that the diagonal of the glass must be able to fit through the door, so we can set up the following equation:

sqrt(8^2 + h^2) <= 3

Squaring both sides of the inequality, we get:

64 + h^2 <= 9

Subtracting 64 from both sides, we get:

h^2 <= -55

Since a square of a real number cannot be negative, there is no solution to this inequality.

Therefore, the glass cannot fit through the door, regardless of the height of the door.

The door must be at least √55 feet tall, which is approximately 7.42 feet, for the 8-foot wide glass to pass through the 3-foot wide door.

To determine how tall the door must be for the glass to pass through, we first need to calculate the height of the glass. Unfortunately, the height of the glass is not provided in the question. Assuming that the height of the glass is less than or equal to the height of the door, we can proceed as follows:

Let's say the height of the glass is h feet. Then, we know that the glass is a rectangular shape with dimensions of 8 feet by h feet. To pass through the door, the glass needs to be able to fit horizontally and vertically through the opening.

Since the door is 3 feet wide, the glass needs to be able to fit through the opening when turned on its side. Therefore, the height of the glass cannot exceed 3 feet.

So, the door must be at least 3 feet tall for the glass to pass through. However, this assumes that the height of the glass is less than or equal to 3 feet. If the height of the glass is greater than 3 feet, then the door would need to be taller to accommodate the glass.

To determine the minimum height the door must be for the 8-foot wide glass to pass through the 3-foot wide door, you can use the Pythagorean theorem. The glass will need to be tilted diagonally as it passes through the door. Let's label the door's height as 'h' and use the formula:

3² + h² = 8²

9 + h² = 64

h² = 64 - 9
h² = 55
h = √55

The door must be at least √55 feet tall, which is approximately 7.42 feet, for the 8-foot wide glass to pass through the 3-foot wide door.
