A negative number is not a real number which, squared, is negative. Hence square root of -4 undefined
What is the square root?
The square root of a number is the factor that we can multiply by itself to get that number. The symbol for square root is √ .Finding the square root of a number is the opposite of squaring a number.
According to the given question:
A negative number is not a real number which, squared, is negative.
You can't get square a number and get a negative. If you square a negative number, it'll become positive, therefore you can't square root a negative number because it doesn't exist. Hence square root of -4 is undefined.

The solution is, Length of the shadow = 11.4 m.
What are trigonometric relations?Trigonometry can be stated as the study of the relationships between the angles and the lengths of the sides of triangles.
here, we have,
The six trigonometric functions are sin , cos , tan , cosec , sec and cot
Let the angle be θ , such that
sin θ = opposite / hypotenuse
cos θ = adjacent / hypotenuse
tan θ = opposite / adjacent
here, we have,
Given the graph:
The length of the shadow = y - x.
• To find x:
tan 21 = x/25
so, we get,
x = 25 * tan 21
=9.6m
• To find y:
tan 40 = y/25
so, we get,
y = 25* tan40
= 21m
Length of the shadow:
length = 21 - 9.6 m
= 11.4m
so, we get,
Length of the shadow = 11.4 m

someone please help with this math question! ill give brainly if its correct
Answer:
x = 50, y = 61
Step-by-step explanation:
y + 8 + 2x + 11 = 180°
y + 2x = 161°
the total of the interior angles of the 5 sided polygon is:
(180 x 5) - 360 = 540°
540 = 98 + 98 + 125 + 108 + 2x + 11
2x = 100
x = 50°
y + 2(50) = 161
y = 61°
The drama department was considering two options for the winter production. They used the following equations to represent the profit, y, they
would make from the sale of tickets, x, minus the costs.
Option A: y= 5x - 1500
Option B: y = 3x - 500
Which graph correctly shows the point after which Option A becomes more profitable than Option B?
Answer:
Graph D is correct
Step-by-step explanation:
This is complicated because the scales on the x-axis and y-axis are not the same. Graph D has the correct y-intercepts and the correct slopes. The solution is x = 500, where the two lines intersect.

Maria and Juan are married, filing jointly. Their taxable income is $154,849. Use the table below to write an equation to determine their tax. Then calculate their tax.
Answer:
The right answer is "$31,399.75".
Step-by-step explanation:
The given value is:
Taxable income,
= $154,849
According to the question,
The tax amount will be:
= [tex]8,962.50 + (154,849 - 65,100)\times 25 \ percent[/tex]
= [tex]8,962.50+(89,749)\times 25 \ percent[/tex]
= [tex]8,962.50+22,437.25[/tex]
= [tex]31,399.75[/tex] ($)
