Determine which answers are solutions of the inequality 2x + 1 > 5
A : x = 7
B : x = - 3
C : x = 0
D : x = 2
E: x = 3
F : x = - 1
Answer:
A and E
Step-by-step explanation:
2x + 1 > 5
So, subtract the 1 from both sides,
2x > 4
x > 2
So anything greater than 2...
7 and 3 are greater than 2.
A and E.
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

Which gives the correct values for points A, B, C, and D?
Answer:
The correct answer is: A
Step-by-step explanation:
Points on a Numeric Line
The numeric line shown in the figure has four points A, B, C, and D. It's clear that each marked division of the line has a value of 1/4 units and all four points are below the reference zero, thus all are negative.
Point A is clearly on the -2 mark, thus
A=-2
Point B is one mark above A, thus it's located at:
[tex]B=-2+\frac{1}{4}=-\frac{7}{4}=-1\frac{3}{4}[/tex]
[tex]B=-1\frac{3}{4}[/tex]
Point C is one mark below -1, thus:
[tex]C=-1-\frac{1}{4}=-1\frac{1}{4}[/tex]
Finally, point D is one mark below 0:
[tex]D=-\frac{1}{4}[/tex]
The correct answer is: A

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

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
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.

PLEASE HELP ME THIS IS DUE IN 10 MINUTES PLEASE HELP ME!! THANK YOU!!
Answer:
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]
[tex]=-179[/tex]
Therefore, the sequence is:
[tex]\:\left\{a_{1,\:}a_2,\:a_3,\:a_4\right\}\:=\:\left\{-10,\:-23,\:-62,\:-179\right\}[/tex]
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 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

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

p. 10 of 19
Answer:
67.7
Step-by-step explanation:
Temperature at beginning of Father's Day = 65.8 degrees
Drop in temperature because of rain = 10.7 degrees
Rise in temperature after the rain the next day = 12.6 degrees
Therefore, temperature at the end of the day after the Father's Day
= Temperature at beginning of Father's Day minus Drop in temperature because of rain plus Rise in temperature after the rain the next day
= 65.8 - 10.7 + 12.6
= 67.7 degrees
NB: The answer was written as only 67.7 as requested by the questioner.

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.
