The length of t to the nearest centimeter is 1083 cm.

Angles are the figure formed by the intersection of two lines or rays by sharing a common point. This point is called the vertex of the angle.

Given that,

u = 750 cm

m ∠U = 42°

m ∠T = 105°

We have the sine rule to find missing length as,

[tex]\frac{u}{sin U}[/tex] = [tex]\frac{t}{sin T}[/tex]

Substituting the measures given,

[750 / sin (42°)] = [t / sin (105°)]

Cross multiplying,

t = [ 750 × sin (105°)] / sin (42°)

t = 1082.59 ≈ 1083 cm

Hence the length of the missing side is 1083 cm.

(a) The exponential growth model is P = 5655 e^(0.014t)

(b) Population of the town in 2022 is 6689.5065.

Population growth is defined as the number of people increasing over years in a specific region calculated using annual growth rate.

(a) The formula to calculate population growth is,

P = P₀ e^(r t)

Given,

Initial population in 2010, P₀ = 5655

Annual growth rate, r = 1.4% = 0.014

Substituting,

P = 5655 e^(0.014t)

(b) To estimate the population of town in 2022,

t = 2022 - 2010 = 12 years

Substituting value of t in the formula in (a),

P = 5655 e^(0.014 × 12)

  = 5655 e^(0.168)

  = 5655 × 1.1829

If the bases of two exponential expressions are different, they cannot be directly compared or combined.

You can convert one of the bases to match the other by using logarithm properties. For example, if you want to compare or combine 2³ and 3², you can convert the base of one of them to match the other by using the logarithm property log3(3²) = 2, so 3² can be rewritten as 2^(log3(3²)) = 2².

If you want to add or subtract exponential expressions with different bases, you can convert one of the bases to match the other by using logarithm properties, then combine the exponents. For example, if you want to add 2³ and 3², you can convert the base of one of them to match the other by using the logarithm property log2(3) = 1.58496, so 3² can be rewritten as 2^(log2(3)*2) = 2^3.18992.

The least whole number possibility for the third side is 8 cm. The greatest whole number possibility for the third side is 22 cm.

A triangle is a three-sided polygon. It is a geometric shape that has three edges and three vertices. Triangles can be classified based on their side lengths (such as equilateral, isosceles, or scalene) or based on the angles between their sides (such as acute, right, or obtuse). Triangles are a fundamental shape in geometry and are used in many branches of mathematics and physics. To form a triangle, the sum of the lengths of any two sides must be greater than the length of the third side.

Using this rule, we can find the possible range of values for the third side of the triangle.

The least possible length of the third side would be:

To write 3 exponents, you can use the following format: base^exponent.

An exponent is a small number that is written slightly above and to the right of a base number. The base is the number being multiplied, and the exponent tells you how many times the base is being multiplied by itself.

For example, to write 3 raised to the power of 2, you would write it as 3^2, which means 3 multiplied by itself 2 times, which is equal to 9.

It's important to note that the exponent is also known as the power, so 3^2, 3^3 and 3^4 are also read as 3 to the power of 2, 3 to the power of 3, 3 to the power of 4.

In summary, to write 3 exponents, you can use the format: base^exponent, where the base is the number being multiplied and the exponent tells you how many times the base is being multiplied by itself. In this case, 3^2, 3^3, and 3^4 represent 3 multiplied by itself 2, 3, and 4 times respectively.

The illustration shows that (A) spring x has a higher elastic potential energy.

The energy that is stored when a force is used to deform an elastic object is known as elastic potential energy.

Until the force is released and the object springs back to its original shape, doing labor in the process, the energy is retained.

Kinetic energy is the power that an object has while in motion.

For instance, a stretched rubber band contains elastic potential energy because, when released, it will spring back to its resting position, converting the potential energy to kinetic energy.
