Answer:

Step-by-step explanation:

The triangles are similar so the sides are proportional.

It is important to match the sides correctly.

Triangle PQR is similar to Triangle STU

So the sides PQ similar to ST

QR similar to TU

PR similar to SU.

We are given one side in the smaller triangle SU which is 6.

SU matches to PR - if you divide PR by SU - 21 ÷ 6 = 3.5

So the sides of the smaller triangle are 3.5 times smaller

PQ = 14 then divide by 3.5 to get ST = 4

QR = 28 then divide by 3.5 to get TU = 8

The angles are much easier.

Similar triangles have the same angle measurement.

Find the corresponding angles.

To find ∠Q - add angles P and R and subtract from 180°.

All triangles interior angles add to 180°.

180 - (70 + 46) = 180 - 116 = 64°

Match up the corresponding angles:

∠S = 70°, ∠T = 64°, ∠U = 46°

SU = 6   ST = 4  TU = 8

So the x-coordinates of the points where the proton crosses the x-axis are x = ±√(5).

In mathematics, a function is a relation between a set of inputs (the domain) and a set of possible outputs (the codomain or range) with the property that each input is related to exactly one output. In other words, a function is a rule or a mapping that assigns a unique output value to each input value. Functions can be represented in various ways, such as equations, tables, graphs, or diagrams. They are used to describe and model a wide range of phenomena in mathematics and other fields, such as physics, engineering, economics, and social sciences. Functions are often denoted by symbols such as "f(x)", "g(x)", or "h(t)" and can be composed or combined to form new functions. They can also be classified according to various properties, such as whether they are continuous, differentiable, invertible, or periodic. In summary, in mathematics, a function is a relation between a set of inputs and a set of possible outputs that assigns a unique output value to each input value.

Here,

To find the x-coordinates of the points where the proton crosses the x-axis, we need to find the roots of the function f(x) = x⁴ - 2x² - 15. These are the values of x that make the function equal to zero, which correspond to the points where the proton crosses the x-axis.

To find the roots, we can use the factoring method or the quadratic formula. In this case, we can factor the function as follows:

f(x) = x⁴ - 2x² - 15

= (x² - 5)(x² + 3)

Setting each factor equal to zero and solving for x, we get:

x² - 5 = 0 or x² + 3 = 0

Solving for x in each equation, we get:

x = ±√(5) or x = ±i*√(3)

1 cm is defined as 1/100 of a meter. One foot is defined as 1/3 of a yard or 12 inches in length. We know that, 1 inch = 2.54 cm and therefore, 23.5 centimeter = 9.252 inches

Centimeters :

The centimeter (cm) is the fractional part of the meter, the international standard unit of length, and equals approximately 39.37 inches. It is defined as 1/100 of a meter.

The centimeter is based on the SI unit of measurement and is equal to one hundredth of a meter as indicated by the prefix "centi". The metric prefix ranges from 10-18 to 1018 in decimal, and the base (metric in this case) has no prefix and a modulus of 1. Exploring the most commonly used metric prefixes such as kilogram, mega, giga, tera, centi, milli, micro, and nano can be useful for quickly navigating metric units.

Inch:

Inches is a unit of length or distance in several systems of measurement, including traditional American units and British Imperial units. An inch is defined as 1/12 of a foot, so 1/36 of a yard. By modern definition, 1 inch equals 25 exactly 4 mm.

The term "inch" comes from the Latin unit "uncial", equivalent to "1/12" in Roman terms. There were several standards for inches in the past and the current definition is based on international yards. One of the earliest definitions of an inch was based on a barley grain, where an inch equals the length of three dry round grains of barley laid end to end. Another version of the inch is believed to be derived from the width of a person's thumb, where length was obtained by averaging the widths of three thumbs (small, medium, and thumb).

By multiplying  the value in centimeters by the conversion factor 0.3937007874021.

So, 23.5 centimeters = 23.5 × 0.39370078740213

It is false that the probability of the union of two events can be more than the probability of the intersection of the two events occurring.

This is because when two events intersect, the intersection of the two events refers to the occurrence of both events at the same time, while the union of the two events refers to the occurrence of either event or both events at the same time. therefore, the union of two events can have a higher probability of occurring than the intersection of two events since the union includes the possibility of both events occurring, while the intersection does not.

For example, let us consider two events, A and B. Event A has a probability of 0.3, and event B has a probability of 0.4. The probability of the intersection of these two events is 0.12(0.3 X 0.4) while the probability of the union of these two events is 0.7(0.3+0.4-0.12). As seen in this example, the probability of the union of two events (0.7) is greater than the probability of the interaction of two events(0.12)
