If the terminal side of angle A passes through (-5,2) find the value of sec A
Answer:
The value of sec A = - √29/5
Step-by-step explanation:
As the terminal side of angle 'A' passes through (-5,2).
so the angle is in the 2nd quadrant.
We can find the length of the hypotenuse using the Pythagorean Theorem
[tex]c^2\:\:=\:\left(-5\right)^2\:+\:2^2[/tex]
[tex]c^2=5^2+2^2[/tex]
[tex]c^2=25+4[/tex]
[tex]c^2=29[/tex]
[tex]c=\sqrt{29}[/tex]
As we know that
cos A = adjacent/hypotenuse
sec A = 1/cosA
= hypotenuse/adjacent
= √29/-5
= - √29/5
Therefore, the value of sec A = - √29/5
A motorcycle make 100 revelation in moving a distance of 220m find the diameter of the wheel
Answer:
Step-by-step explanation:
If it goes 220 meters and has made 100 revolutions that means that each revolution is 220 meters / 100 = 2.2 meters.
That's the same thing as saying that the wheel has a circumference of 2.2 meters.
Circumference = 2*pi * r = pi * d
2 = pi * d
2 = 3.14 * d
2/3.14 = d
d = 0.6369 meters

Answer:
(224)10 = (E0)16
I dont know why it wouldnt be right this is the answer...Im acually confused now
Step-by-step explanation:
(224)10 = (E0)16
Step by step solution
Step 1: Divide (224)10 successively by 16 until the quotient is 0:
224/16 = 14, remainder is 0
14/16 = 0, remainder is 14
Step 2: Read from the bottom (MSB) to top (LSB) as E0. This is the hexadecimal equivalent of decimal number 224
Time traveler can take 5 books with him and he has 79 books to choose from how many different ways can the books be selected
We are given:
The time-traveller has 79 books, but he can only take 5 books
since we need to find the number of ways he can choose 5 books, we know that the order in which he takes the books does NOT matter
Hence, we will use combination
Finding the number of ways:
Since we will use combination, ₇₉C₅
We know that the formula for combination is (n!) / (r!(n-r)!)
₇₉C₅ = 79! / 5!(74!)
₇₉C₅ = 22,537,515
Therefore, the time traveller can choose 5 books in 22,537,515 different ways

If carpet is 1.49 per square foot, how much will it cost for them to get new carpet for the master bedroom.
Answer:
The new carpet for the master room will cost $379.30
Step-by-step explanation:
The bedroom is a rectangle of dimensions:
[tex]4\sqrt {3}+6\sqrt {3}=10\sqrt {3}~ft[/tex]
[tex]6\sqrt {6}~ft[/tex]
Thus, the area of the master bedroom is:
[tex]A=10\sqrt {3}~ft*6\sqrt {6}~ft[/tex]
Multiply the coefficients and the arguments:
[tex]A=60\sqrt {18}~ft^2[/tex]
Calculating:
[tex]A=254.56~ft^2[/tex]
The carpet unit cost is $1.49 per square foot, thus the total cost of the new carpet is:
$1.49*254.56=$379.30
The new carpet for the master room will cost $379.30
What is the value of g?
-5+7g=3g+ 9
Answer:
g = 7/2
Step-by-step explanation:
-5 + 7g = 3g + 9
~Add 5 to both sides
7g = 3g + 14
~Subtract 3 to both sides
4g = 14
~Divide 4 to both sides
g = 14/4 or g = 7/2

Graph the following equation: y=2x+1
Answer:
There you go
Step-by-step explanation:
The graph of y=2x+1 is given in the attachment and the graph has a slope of 2.
What is Graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
The given equation is y=2x+1
y equal to two times of x plus one.
The given equation in the form of slope intercept form y=mx+b in which the value of m or slope is 2.
Now we have to find some values of x and y to plot the graph
When x=0
the value of y is 2(0)+1=1
When x=1
y=2(1)+1
y=3
When x=2
y=2(2)+1
y=5
When x=3
y=2(3)+1
y=7
After plotting all these points we draw the graph which is given in the attachement.
Hence, the graph of y=2x+1 is given in the attachment and the graph has a slope of 2.

cos4θ-cos2θ/sin4θ+sin2θ
Answers:
A. cotθtanθ
B. -cotθ
C. -tanθ
D. -1
Recall the double angle identities:
cos(2θ) = 1 - 2 sin²(θ)
sin(2θ) = 2 sin(θ) cos(θ)
With some rewriting, we can get
cos(4θ) - cos(2θ) = 2 cos²(2θ) - 1 - cos(2θ) = (2 cos(2θ) + 1) (cos(2θ) - 1)
and
sin(4θ) + sin(2θ) = 2 sin(2θ) cos(2θ) + sin(2θ) = sin(2θ) (2 cos(2θ) + 1)
The numerator and denominator both share a factor of 2 cos(2θ) + 1; canceling them leaves us with
(cos(2θ) - 1) / sin(2θ)
Replace cos(2θ) = 1 - 2 sin²(θ) and sin(2θ) = 2 sin(θ) cos(θ) :
((1 - 2 sin²(θ)) - 1) / (2 sin(θ) cos(θ))
-2 sin²(θ) / (2 sin(θ) cos(θ))
- sin(θ) / cos(θ)
- tan(θ)
so the answer is C.
Answer:
(cos4θ-cos2θ)/(sin4θ+sin2θ)
-[2sin((4θ+2θ)/2)sin(2θ-4θ)/2)]/[2sin((4θ+2θ)/2)cos (4θ-2θ)/2)]-sinθ/cosθ-tanθC. -tanθ is your answer.

A car tire has a radius of 10.4 inches. What distance will the tire travel after 20 rotations?
Answer:
Distance traveled after 20 rotations = 1306.24 inches
Step-by-step explanation:
r = 10.4 inches
Distance traveled in one rotation = Circumference of the car tire
Circumference of the car tire = 2πr
= 2 * 3.14 * 10.4
= 65.312 inches
Distance traveled after 20 rotations = 65.312 * 20
= 1306.24 inches
Captain Hook, Captain Sparrow and Long John Silver split a treasure in the ratio 2:5:7. Long John Silver received the greatest portion. Captain Hook received the smallest portion, which was 1000 pounds. How many pounds was the total weight of Long John Silver’s portion of the treasure?
Answer: 3500 pounds
Step-by-step explanation:
Captain Hook: the "2" in the ratio. He got 1000 pounds of treasure so we write a ratio:
2:1000 = 1:500
John Silver: the "7" in the ratio. The ratio then becomes:
1(7):500(7) = 7:3500. His treasure weighs 3500 pounds

The sequence is:
[tex]\:\left\{a_{1,\:}a_2,\:a_3,\:a_4\right\}\:=\:\left\{-10,\:-23,\:-62,\:-179\right\}[/tex]
Step-by-step explanation:
Given the recursive function
[tex]a_n=3a_{n-1}+7[/tex]
As the first term is -10.
i.e.
[tex]a_1=-10[/tex]
Putting n = 2 to determine the 2nd term
[tex]a_n=3a_{n-1}+7[/tex]
[tex]a_2=3a_{2-1}+7[/tex]
[tex]a_2=3a_1+7[/tex]
[tex]= 3(-10)+7[/tex] ∵ [tex]a_1=-10[/tex]
[tex]= -23[/tex]
Putting n = 3 to determine the 3rd term
[tex]a_n=3a_{n-1}+7[/tex]
[tex]a_3=3a_{3-1}+7\:\:[/tex]
[tex]a_3=3a_2+7\:\:\:\:\:[/tex]
[tex]= 3(-23)+7[/tex] ∵ [tex]a_2=-23[/tex]
[tex]= -62[/tex]
Putting n = 4 to determine the 4th term
[tex]a_n=3a_{n-1}+7[/tex]
[tex]a_4=3a_{4-1}+7[/tex]
[tex]a_4=3a_3+7\:\:\:\:\:[/tex]
[tex]= 3(-62)+7[/tex] ∵ [tex]a_3=-62[/tex]
