Find the area of a regular hexagon with an apothem length of 12.1 and a side length of 14
Answer:
area = 520 units²
Step-by-step explanation:
divide the hexagon into 6 equal triangles.
each triangle has a base of 14 and a height of 12.1 so:
the area of one triangles = 1/2BH = 1/2(14)(12.1) = 86.8 units ²
86.8 x 6 triangles = 520.8 units²
what is the sum of -7/18 and - 3/6 A) 4/9 B)-8/9 C) 4/9 D) 8/9
Answer:
B) -8/9
Step-by-step explanation:
multiply - 3/6 by three to have the same denominator as -7/18 so that they can add up
=> -9/18 + (-7/18) = -16/18 = -8/9
Answer:
The volume of this rectangular prism is 225 sqaure centimeters.
Step-by-step explanation:
The formula for finding volume is V = length * width * height
Substitute values in the formula:
5 * 15 * 3 = V
5 * 15 * 3 = 225

A circle has a diameter of 18. The sector has a central angle of 30 degrees. What is the area of the sector?
Answer:
21.21
Step-by-step explanation:
Area of a circle is A = π r^2
Variables:
r = 18/2 = 9
θ = 30 deg
Find the area:
A = π r^2
A = π 9^2
A = 254.47
Find the area of the sector:
θ/360 * A
= 30/360 * 254.47
= 21.21

Although being a military defeat, the Tet Offensive was a stunning propaganda win for communists. In fact, it is frequently regarded for changing the tide of the war in their favour.
As Viet Cong rebels invaded rural areas previously held by the South Vietnamese government, the South Vietnamese began to lose authority.
Despite tremendous deaths, North Vietnam secured a strategic triumph with the Tet Offensive, which represented a watershed moment in the Vietnam War and the start of the protracted, agonising American withdrawal from the region.

Do
Wed Apr 21
Answer:
Options C and D are the correct options.
Step-by-step explanation:
Option A
cos(H) = 0.3846
By applying cosine rule in ΔFGH,
cos(H) = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]
= [tex]\frac{36}{39}[/tex]
= 0.9231
False
Option B
cos(G) = 0.9231
By applying cosine rule in ΔFGH,
cos(G) = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]
= [tex]\frac{15}{39}[/tex]
= 0.3846
False
Option C
sinG = 0.9231
By applying sine rule in ΔFGH,
sin(G) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]
= [tex]\frac{36}{39}[/tex]
= 0.9231
True
Option D
tanG = 2.4
By applying tangent rule in ΔFGH,
tanG = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]
= [tex]\frac{36}{15}[/tex]
= 2.4
True
Therefore, Options C and D are the correct options.
Ann purchased a prepaid phone card for $20. Long distance calls cost 14 cents a minute using this card. Ann used her card only once to make a long distance call.If the remaining credit on her card is 14.26,how many minutes did her call last?
Answer:
The correct answer is; Ann was on the call for 41 minutes.
Step-by-step explanation:
20-14.26 is equivalent to 5.74, in which you divide that by .14 (fourteen cents) and get 41.

integrate the following:
[tex] \displaystyle \int \frac{ \cos ^{2} (x) - \cos ^{2} ( \alpha ) }{ \cos( x) - \cos( \alpha ) } [/tex]
Answer:
[tex] \displaystyle \sin(x) + x\cos( \alpha ) + \rm C[/tex]
Step-by-step explanation:
we are given
[tex] \displaystyle \int \frac{ \cos ^{2} (x) - \cos ^{2} ( \alpha ) }{ \cos( x) - \cos( \alpha ) } dx[/tex]
we want to Integrate it
notice that, the denominator can be rewritten by using algebraic identity
remember that,
[tex] \displaystyle {a}^{2} - {b}^{2} = ( a + b)(a - b)[/tex]
therefore
rewrite the denominator by using the identity:
[tex] \displaystyle \int \frac{ ((\cos (x) + \cos ( \alpha) ) ( \cos(x) - \cos( \alpha ) ) }{ \cos( x) - \cos( \alpha ) }dx [/tex]
reduce fraction:
[tex] \displaystyle \int \frac{ ((\cos (x) + \cos ( \alpha) ) ( \cancel{ \cos(x) -\cos( \alpha ) ) }}{ \cancel{\cos( x) - \cos( \alpha ) } }dx[/tex]
[tex] \displaystyle \int \cos(x) + \cos( \alpha ) dx[/tex]
recall that,
[tex] \rm\displaystyle \int f(x) \pm g(x)dx =\int f(x) \pm \int g(x)dx[/tex]
by that
we get
[tex] \displaystyle \int \cos(x) dx + \int \cos( \alpha )dx [/tex]
we also know that,
[tex] \displaystyle \int \cos(x) = \sin(x)dx [/tex]
and also the Integration of a constant is always cx
so,
[tex] \displaystyle \sin(x) + x\cos( \alpha ) [/tex]
and of course we have to add constant
[tex] \displaystyle \sin(x) + x\cos( \alpha ) + \rm C[/tex]

expression is equivalent to Brit's expression. Justify your reasoning.
Answer: I believe it is
Step-by-step explanation: if you add 3x + 3x you get 6x. You would then add the like terms which are x + x ( x is equal to one) and that to 6x and you get 8x then add 2+2=4 and you get 8x + 4

What is the amount of income tax in dollars and cents if a plumber makes $51,482 and has to pay a 5.5% income tax rate? $2,821.51
Answer:
$2,821.51
Step-by-step explanation:
The amount made be plumber = $51,482
rate of income tax = 5.5%
Therefore, amount of income tax in dollars and cents that would be paid by the plumber would be 5.5% of his amount made
= 5.5% of 51482
= (5.5/100)×51,482
= $2,821.51

A tire on a vehicle has a diameter of 30in. As it moves down the
road it makes 50 full revolution. What is the approximate distance
it traveled?
Answer:
94.25 in
Step-by-step explanation:
In one revolution, the tire moves a distance equal to its circumference. If the diameter is 30 in, the radius is half of that, 15 in. Circumference is 2 pi times the radius:
[tex]C=2\pi r= 2\pi (15) = 30\pi \approx 94.25 \text{ in.}[/tex]
