prove that [tex]2/\sqrt{3} cosx + sin x= sec(\pi /6-x)[/tex]
Answer:
sec(π/6 - x) = R.H.S = 2/(√3cosx + sinx) = L.H.S.
Step-by-step explanation:
sec(π/6 - x) = 1/cos(π/6 - x)
Using compound angle formula,
cos(A - B) = cosAcosB + sinAsinB where A = π/6 and B = x.
So, cos(π/6 - x) = cos(π/6)cosx + sin(π/6)sinx , cosπ/6 = √3/2 and sinπ/6 = 1/2
cos(π/6 - x) = cosπ/6cosx + sinπ/6sinx = (√3/2)cosx + (1/2)sinx
sec(π/6 - x) = 1/cos(π/6 - x)
= 1/(√3/2)cosx + (1/2)sinx = 2/(√3cosx + sinx)
= L.H.S
So, sec(π/6 - x) = R.H.S = 2/(√3cosx + sinx) = L.H.S
Dylan and 6 of his friends ate lunch together. The restaurant charges 18% for gratuity for groups of 6 or more people, and tax is 6%. Their total bill, without tax and gratuity was $98. Part 1 Which expression will find the additional charge, in dollars, Dylan and his friends will need to pay? A. 98 + (0.18 + 0.6) B. 98(0.6 + 0.18) C. 98(0.06 + 0.18) D. 98(0.18) + 0.06
Answer: C: $98*(0.06 + 0.18)
Step-by-step explanation:
Always when we have a percentage X% of charge of an amount of money, suppose $100.
The actual cost will be:
(x)*$100 = C.
Where x is the decimal representation of X%:
x = (X%/100%)
In this case, we have two additional charges:
One of 18% and another of 6%.
First we can write them in decimal form:
18%/100% = 0.18
6%/100% = 0.06.
If the price without tax is $98, then the price with the charges will be:
P = (0.18 + 0.06)*$98
The correct option is C.
Answer:
The answer is C hope this helps!

A triangular pyramid has a base shaped like an equilateral triangle. The legs of the equilateral triangle are all 4 centimeters long, and the height of the equilateral triangle is 3.5 centimeters. The pyramid's slant height is 8 centimeters. What is its surface area?
Answer:
The surface area is 55 cm².
Step-by-step explanation:
The formula to compute the surface area of the triangular pyramid is:
[tex]SA=(0.50\times \text{Base Perimeter}\times h)+\text{Base Area}[/tex]
Here h is the slant height.
Compute the Base perimeter as follows:
Perimeter of the equilateral triangle = 3 × side
= 3 × 4
= 12 cm
Compute the Base area as follows:
Area of the equilateral triangle = 0.50 × side × height
= 0.50 × 4 × 3.50
= 7 cm²
Compute the surface area as follows:
[tex]SA=(0.50\times \text{Base Perimeter}\times h)+\text{Base Area}[/tex]
[tex]=(0.50\times 12\times 8)+7\\=48+7\\=55\ \text{cm}^{2}[/tex]
Thus, the surface area is 55 cm².

If point C is between points A and B and AB = 41, AC = 5x, BC = 3x – 7,
what is the value of x?
I NEED HELP ASAP
Answer:
x=6
Step-by-step explanation:
We know that point C is in the middle of point A and point B.
That means that when these two equations are added they should be equal to the length of AB which is 41.
5x+3x-7=41
add 7 to both sides
8x=48
divide both sides by 8.

What number should be placed in the box to help complete the division calculation?
Numerical Answers Expected!
Answer:
The answer to your question is given below.
Step-by-step explanation:
To divide 2635 by 17 using long division method, we simply do the following:
2635 ÷ 17
17 can not go into 2. Therefore, we try 17 into 26, keeping 35 constant.
26 ÷ 17 = 1
Put the 1 on top.
Multiply 17 by 1
17 x 1 = 17
Subtract 17 from 26
26 – 17 = 9
Put the 9 in from of 35 to become 935
Next:
935 ÷ 17
17 can not go into 9. Therefore, we try 17 inot 93 keeping 5 constant.
93 ÷ 17 = 5
Put the 5 on top together with the 1 to become 15.
Multiply 17 by 5
17 x 5 = 85
Subtract 85 from 93
93 – 85 = 8
Put the 8 in front of 5 to become 85
Next:
85 ÷ 17
17 can not go into 8. Therefore, we try 85
85 ÷ 17 = 5
Put the 5 on top together with 15 to become 155
Multiply 17 by 5
17 x 5 = 85
Subtract 85 from 85
85 – 85 = 0
Since no number is remaining, we shall stop here.
Therefore,
2635 ÷ 17 = 155

Given TS¯¯¯¯¯¯¯ and TU¯¯¯¯¯¯¯ are midsegments, PR=18.2, TS=6.5. Find QU . A. 9.1 B. 3.25 C. 13 D. 6.5
Answer:
The correct option is;
D. 6,5
Step-by-step explanation:
TS and TU are midsegments
Segment PR = 18.2
Segment TS = 6.5
Given that TS is the midsegment of PR and PQ, therefore, TS = 1/2×QR
Which gives;
Segment QR = 2×TS = 2 × 6.5 = 13
Segment QR = 13
Given that TU is a midsegment to PQ and QR, we have that QU = UR
Segment QR = QU + UR (segment addition postulate)
Therefore, QR = QU + QU (substitute property of equality)
Which gives;
QR = 2×QU
13 = 2×QU
Segment QU = 13/2 = 6.5
The length of segment QU is 6.5.
What is the volume of a cylinder, in cubic centimeters, with a height of 8 centimeters
and a base diameter of 16 centimeters? Round to the nearest tenths place
Answer:
1608.5 cm³
Step-by-step explanation:
Use the cylinder volume formula, V = [tex]\pi[/tex]r²h
If the diameter is 16 cm, then the radius is 8 cm.
Plug in the radius and height into the formula, and solve:
V = [tex]\pi[/tex]r²h
V = [tex]\pi[/tex](8)²(8)
V = [tex]\pi[/tex](64)(8)
V = 1608.5
So, to the nearest tenth, the volume of the cylinder is 1608.5 cm³
