A triangle is said to be right angle if one of the angles is 90 degrees, the value of the side x for the given right angle triangle is 50.51.

A triangle is a 3-sided shape that is occasionally referred to as a triangle. There are three sides and three angles in every triangle, some of which may be the same.

The sum of all three angles inside a triangle will be 180° .

The given right-angle triangle has the following sides,

AC = Base

BC = Perpendicular

AB = Hyp.

By tan function,

Since,tanθ = Perp/Base

tan29° = 28/x

x = 50.51

Hence, "A triangle is said to be right angle if one of the angles is 90 degrees, the value of the side x for the given right angle triangle is 50.51".

What is an exponent?

Exponent is the process of expressing large numbers in terms of powers. In other words, the exponent describes how many times a number has been multiplied by itself.

According to the zero exponent rule, any base with a zero exponent is equal to one. For instance, [tex]x^{0} = 1[/tex].

We have,

[tex]= \frac{1.25\\ * \\ 10^{-3}}{1.25 \\ * \\ 10^{-3}}[/tex]

[tex]= \frac{1.25\\ * \\ 10^{-3}}{1.25 \\} * 10^{3}[/tex]

Using the multiplication rule of fraction [tex]a\cdot \frac{b}{c}=\frac{a\:\cdot \:b}{c}[/tex]

[tex]= \frac{1.25 \ * \ 10^{-3} \ * \ 10^{3}}{1.25 \\}[/tex]

= [tex]= 10^{-3} * 10^{3}[/tex]

By applying the exponent rule [tex]\:a^b\cdot \:a^c=a^{b+c}[/tex] we get,

Add or subtract the numbers = 3 + 3 = 0

[tex]= 10^{0}[/tex]

By applying the rule [tex]a^{0} = 1[/tex], [tex]a \neq e^{0}[/tex]

= 1

Hence, by solving the above fraction equation we get the answer is 1.

The surface area of the largest sphere that could fit into the rectangular box of dimensions 12 in x 14 in x 18 in is 324π inches²

The surface area of sphere = 324π inches²

What is a Sphere?

A sphere is symmetrical, round in shape. It is a three dimensional solid, that has all its surface points at equal distances from the center. It has surface area and volume based on its radius. It does not have any faces, corners or edges.

The Surface Area of a Sphere = 4πr²

The Volume of a Sphere = ( 4/3 ) πr³

where r is the radius of the sphere

Given data ,

Let the surface area of the Sphere be = S

Let the dimensions of the rectangular box be L x W x H

12 inches x 14 inches x 18 inches

Now , for the surface area of the sphere to have the largest surface area , the radius should be maximum

From the rectangular box , we can see that the height of the rectangle is best suited as the diameter of the sphere

So , Height of the Box = Diameter of the Sphere

And , Radius of the sphere = Height of the Box / 2

                                             = 18 / 2

Radius of the sphere = 9 inches

Now ,

Surface Area of a Sphere = 4πr²

r = 9 inches

Substituting the values in the equation , we get

Surface Area of a Sphere S = 4 x π x ( 9 )²

                                              = 4 x π x 81

                                              = 324π inches²

Therefore , the value of S is 324π inches²

Hence , The surface area of sphere = 324π inches²

The number of miles (m) between the two cities as represented in the equation given 2[(4m * 3.5) / 400] = 171.5 is 2450 miles

The definition of an equation is a mathematical statement that shows that two mathematical expressions are equal. For instance, 3x + 5 = 14 is an equation, in which 3x + 5 and 14 are two expressions separated by an ‘equal’ sign. The most basic and simple algebraic equations consist of one or more variables in math.

In the equation given;

2[(4m * 3.5) / 400] = 171.5

Using changing the subject of formula to find the miles travelled;

2[(4m * 3.5) / 400] = 171.5

28m / 400 = 171.5

28m = 400 * 171.5

Definitions

Note:  Assume that each square on the given graphs is 1 unit.

As there are arrows at both endpoints of the curve, the domain of the function is unrestricted.

The curve has a maximum point at (2, 4) and continues indefinitely towards negative infinity at both endpoints.

Therefore, the range of the function is restricted.

As there are arrows at both endpoints of the function, the domain is unrestricted.

The function has a minimum point at y = 3.

When x > -2, the line continues indefinitely at y = 3.

When x < -2, the line continues indefinitely towards infinity.

Therefore, the range of the function is restricted.

The domain of the function is restricted since there is a closed circle at one endpoint: (-2, -3).  When x > -2, the line continues indefinitely towards infinity.

The function has a minimum point at (-2, -3). As x continues towards infinity, so does y.

Therefore, the range of the function is restricted.

The additional weeks, w, will it take for their total distance run to be equal is 7 weeks.

From the information, Laura has already

run 36 miles and begins running 21 miles per week. This will be 36 + 21w.

Kirk has run 64 miles and runs 17 miles per week. This will be 64 + 17w

where w = number of weeks

This will be equated as:

36 + 21w = 64 + 17w

Collect like terms

21w - 17w = 64 - 36

4w = 28

Divide

w = 28/4

Answer: y=5 is the asymptote answer

Step-by-step explanation:

9.65+0.4=10.05

16.058-1.2=14.858

Answer:

y=-2x-2

Step-by-step explanation:

If the endpoints of the line segment are (7,4) and (-9,-4), that means that the slope will be:

[tex]\frac{-4-4}{-9-7}[/tex] = [tex]\frac{-8}{-16}[/tex]=[tex]\frac{1}{2}[/tex]. For the perpendicular bisector to be perpendicular to the line, it must have a perpendicular slope, which will be the negative reciprocal of [tex]\frac{1}{2}[/tex], which is -[tex]2[/tex]. The perpendicular bisector must also go through the midpoint of the segment, which is (-1, 0) because -1 is the average of 7 and -9 and 0 is the average of 4 and -4.

Now we find the equation!

y=mx+b. Plug in -[tex]2[/tex]     as the "m", or slope:

y=-[tex]2[/tex]x+b

Now, plug in the point (-1, 0):

0=-[tex]2[/tex]*-1+b

0=[tex]2[/tex]+b

b=-[tex]2[/tex]

So, we have m=-[tex]2[/tex] and b=-[tex]2[/tex] and we can form our equation!

y=-[tex]2[/tex]x-[tex]2[/tex]

The mathematical expression f(x)=exp or e^x denotes the exponential function. The word, unless specifically stated differently, normally refers to the positive-valued function of a real variable, though it can be extended to complex numbers or adapted to other mathematical objects.

Given that f(x) is an exponential function where f(-3) = 11 and ƒ(4) = 55. The value of the exponential function will be calculated as,

[tex]y=ax^b[/tex]

[tex]11=a(-3)^b\\55=a(4)^b[/tex]
