Answer:
56.54in^2
Step-by-step explanation:
Answer:
18π in^2 (roughly 56.5 in^2)
Step-by-step explanation:
The area of a semicircle is half the area of a circle. So the area would be 1/2πr² instead of πr².
Since the diameter is 12 inches, the radius would be half of that, making the radius r=12/2=6 inches.
Plugging in r=6 into our formula, we see that the area of the semicircle is 1/2π(6)²=1/2π(36)=18π inches^2
So your final area is 18π in^2 (roughly 56.5 in^2)

The solution of the expression 49x¹⁸ will be 7x⁹.
What is a radical expression?Expression in maths is defined as the relation of numbers variables and functions by using mathematical signs like addition, subtraction, multiplication, and division.
The radical sign, which may be read as either the nth root of x or x radical n, expresses the root of a number. The vinculum, or horizontal line that encircles the number, and the radicand, or number beneath it, are both technical terms.
The given expression is 49x¹⁸. The value of the expression will be solved as:-
E = √( 49x¹⁸)
E = √ (7² x x¹⁸ )
E = 7x⁹
Therefore, the square root will be equal to 7x⁹.

Two observers are standing on shore ½ mile apart at points A and B and measure the angle to a sailboat at a point C at the same time. Angle A is 63° and angle B is 56°. Find the distance from each observer to the sailboat. Round to the nearest hundredth of a mile.
Answer:
Step-by-step explanation:
The length 0.51 miles and 0.47 miles are the distances from each observer to the sailboat.
What is the Sine Rule?The Law of Sines (also called the Sine Rule) is defined as it relates all three sides of a triangle with an angle of a triangle.
Triangle is a basic polygonal shape of a triangle that has three sides and three interior angles. It is one of the fundamental shapes in geometry.
As per the given question, the given data as:
A = 63
B = 56
C = 61 (because these angles should add up to 180)
c = 1/2
We know that the Sine Rule,
sin 63 / a = sin 61 / .5
a = 0.51 miles
sin 56 / b = sin 61 / .5
b = 0.47 miles
Therefore, the length 0.51 miles and 0.47 miles are the distances from each observer to the sailboat.

In the interval 0° < x < 360°, find the values of x for which sin x = 0.6691 Give your answer tot he nearest degree
Answer:
x are 42 and 138degees
Step-by-step explanation:
Given the expression sin x = 0.6691
sin x = 0.6691
Take the sin inverse of both sides
sin⁻¹(sin x) = sin⁻¹(0.6691 )
x = sin⁻¹(0.6691 )
x = 41.99
x = 42 degrees (to the nearest degree)
Since sin theta is positive in the second quadrant;
x = 180 -theta
x = 180 - 42
x = 138degrees
Hence the value of x are 42 and 138degees
One number is 60 more than another. If the larger number is divided by the smaller number, the quotient is 4.
What are the numbers?
Answer:
80 and 20
Step-by-step explanation:
Let the 1st no. be 'x'.
2nd no. should be 'x + 60'.
If the larger no.(x + 60) is divided by the smaller number(x), the quotient is 4.
=> (x + 60)/x = 4
=> x + 60 = 4x
=> 60=4x-x
=> 60=3x
=> 60/3 = x
=> 20 = x
No. are x = 20 and x+60 = 20+60= 80

[tex] = - \sqrt[3]{ \frac{2 \times 2 \times 2}{3 \times 3 \times 3} } [/tex]
[tex] = - \frac{2}{3} (ans)[/tex]
[tex]3. \: a. \: 10 - 2 \sqrt{9} [/tex]
