Answer:

50.40 cm2

Step-by-step explanation:

Area of the polygon AFGBH = Area of ∆ACF + Area of rectangle FCEG + Area of ∆GEB + Area of ∆ABH

= 3.6 cm2 + 4.32 cm2 + 21.6 cm2 + 6.48 cm2 + 14.4 cm2

= 50.40 cm2

Hence, the required area = 50.40 cm2.

When camera has an angle of depression of 50° to a point on the floor and the other camera has an angle of depression of 60° to the same point calculate the height of the gym, the height of gym is 7.05 m

When the observer is above the object they are looking at, an angle of depression is created. An angle below the horizontal line drawn with the level of the observer's eye and the line connecting the object with the observer's eye is created when an observer looks at an object that is placed at a distance lower than the observer.

Lets name the points on the triangles as A, B ,C

m∠ABC = 180° - 60° + 50°

             = 70°

Now, the sine theorem defines

[tex]\frac{AB}{sin50\textdegree}[/tex] = [tex]\frac{AC}{sin70\textdegree}[/tex] = [tex]\frac{10}{sin70\textdegree}[/tex]

AB = 8.15 meters

Now using the area of triangle formula

area∠ABC = 1/2 × AB × AC × sin∠BAC = 1/2 × h × AC

⇒ 1/2 × 8.15 × 10 × √3/2 = 1/2 × h × 10

⇒ 8.15 × √3/2 = h

⇒ h = 7.05

What is profit and loss?

If the selling price is more than the cost price, then the difference between the selling price and the cost price will give the profit.

If the selling price is less than the cost price, then the difference between the selling price and the cost price will give the loss.

The likelihood that someone has received a vaccination equals one minus the likelihood that no one has. The likelihood that a randomly chosen individual in a large population IS NOT immunized = 1 - 0.54 = 0.46.

The likelihood that the three randomly chosen individuals are not all immunized is 0.463, hence the likelihood that at least one of them has been immunized is 1 - 0.463.

The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.

The probability is computed by dividing the total number of possible outcomes by the number of possible ways the event could occur. Probability and odds are two distinct ideas. Odds are calculated by dividing the likelihood of an event by the likelihood that it won't.

Triangle      12          15          90             4              360

The surface area is 504 square inches

The square prism represents the given parameter

On the figure, we have the following highlights:

Shape: Square

Also, we have

Shape: Triangle

This means that

Area of 1 square = Base length * Height

Area of 1 square = 12 inches * 12 inches

Area of 1 square = 144 square inches

So, the area of all squares in the figure is

Area of all squares = 1 * 144 square inches

Area of all squares = 144 square inches

Also, we have

Area of 1 triangle = 0.5 * Base length * Height

Area of 1 triangle = 0.5 * 12 inches * 15 inches

Area of 1 triangle = 90 square inches

So, the area of all triangles in the figure is

Area of all triangles = 4 * 90 square inches

Area of all triangles = 360 square inches

The surface area of the figure is

Surface area = Area of all triangles + Area of all squares

This gives

Surface area = 360 square inches + 144 square inches

Evaluate

Surface area = 504 square inches

Hence, the surface area of the prism is  504 square inches

Step-by-step explanation:

Solution of the given function g(x) = "-x^2" "-7" when x=-3  = 2.

A mathematical phrase, rule, or law that establishes the link between an independent variable and a dependent variable (the dependent variable). In mathematics, functions exist everywhere, and they are crucial for constructing physical links in the sciences.

A function called g is defined by the notation y=g(x). This should be understood as "y is a function of x." The input value, or independent variable, is represented by the letter x. The output value, also known as the dependent variable, is denoted by the letter y, or g(x).

Given function

g(x) = -x² -7When x = -3

Whenever you're given a function, you simply plug in the x  value you're given and then calculate the result.

g(-3) =(-3²) - 7

g(-3) =(9) - 7

g(-3) =9 - 7

g(-3) =2

Hence, When x=-3 = 2, the given function g(x) has a solution of "-x2" "-7."

Answer:

$60.00

Step-by-step explanation:

15 is 25% of a number. 25 times 4 equals 100. so 15 times four is 60, making 60 the 100%

Work Shown:

x = original price

75% of x = 0.75x = amount saved

x - 0.75x = 0.25x = final price after discount = 15

0.25x = 15

x = 15/0.25

x = 60

The equation of the parallel line to y = 2x - 1, that passes through (-3, 1) is: y = 2x + 7.

Two lines that are parallel to each other would always have the same slope (m). In the slope-intercept form of the equation that represents a line, y = mx + b, the slope of the line is represented as "m", while the y-intercept is represented as b.

Given:

A point (-3, 1)

Equation, y = 2x - 1. The slope (m) = 2. Since parallel lines have the same slope (m), therefore, the line that passes through (-3, 1) also have a slope (m) = 2.

Substitute (x, y) = (-3, 1) and m = 2 into y = mx + b:

1 = 2(-3) + b

1 = -6 + b

1 + 6 = b

b = 7

To write the equation of the parallel line to y = 2x - 1, substitute m = 2 and b = 7 into y = mx + b:

The exact area of the shaded region is: (2 - √6)/8 cm².

The area of a triangle = 1/2(base)(height).

The area of the shaded region = area of triangle ABD - area of triangle ACD.

Area of triangle ABD:

Base of triangle ABD = AD = √2/2

Height of triangle ABD = BD = √2/2

Area of triangle ABD = 1/2(√2/2)(√2/2)

Area of triangle ABD = 2/8 = 1/4 cm²

Area of triangle ACD:

Base of triangle ACD = AD = √2/2

Height of triangle ACD = CD = √3/2

Area of triangle ACD = 1/2(√2/2)(√3/2)
