What is the value of 2cos2(105⁰) − 1?
Answers
Step-by-step explanation:
-1 - root3
The value of the given expression 2cos2(105⁰) − 1 is,
⇒ - 1 - √3
What is trigonometric functions?A right-angled triangle's angle can be related to side length ratios using trigonometric functions, which are real functions in mathematics. They are extensively used in all geosciences, including navigation, solid mechanics, celestial mechanics, geodesy, and many others.
We have to find the value of;
⇒ 2cos2(105⁰) − 1
Now, We can Plug 105° = θ
So, the expression becomes,
⇒ 2cos2θ - 1
Using the formula;
cos2θ = 1 - 2sin^2θ
We get;
⇒ 2cos2θ - 1 = 2(1-2sin^2θ) - 1
= 2 - 4sin^2θ - 1
⇒ 2cos2θ - 1 = 1 - 4sin^2θ
Now, Again plug θ = 105°
⇒ 2cos2(105°) - 1 = 1 - 4sin¹⁰⁵
⇒ 2cos2(105°) - 1 = -1 - √3
Hence, The value of the given expression is,
⇒ (-1 - √3)

Answer:
m∠ABC = 81°
m∠FEC = 90°
Step-by-step explanation:
The median BE of isosceles triangle ABC is also an altitude and the angle bisector of ∠ABC. This means ...
m∠ABC = 2×m∠ABE = 2(40°30')
m∠ABC = 81°
It also means that all of the angles at the intersection of BF and AC are right angles, so ...
m∠FEC = 90°

Answers
Answer:
t ≤ 4.5
Step-by-step explanation:
We are told that the goal is to walk at least 18 miles
She walks at a rate of 4 miles per hour, speed is 4mph
Required
the inequality for the time taken to walk the distance and the said speed
Step two:
we know that
speed= distance/time
time=distance/speed
substitute
time= 18/4
time= 4.5 hours
Time≤ 4.5 hours

Step-by-step explanation:
1) Look at the equation as a multiplication of 3 parts:
16 * ( p -2) * (7p + 4)
2) Multiply 16 with (p-2) = 16p - 32
3) Multiply 16p - 32 with (7p + 4) = 112p^2 + 64p - 224p - 128
4) Simplify: 112p^2 - 160p -128

The cost of mailing a first-class letter is $0.46 for the first ounce and $0.20 for each additional ounce or portion of an ounce. Y is the total cost for mailing a letter that weighs x ounces. What is the cost of mailing a first class letter weighing 2.5 ounces based on the guidelines given in the previous problem?
Answers
Answer:linear function
Step-by-step explanation:
The cost of mailing a first class letter weighing 2.5 ounces is $0.96,
What are linear equation?A linear equation only has one or two variables. No variables in a linear equation is raised to power greater than 1 or used as denominator of a fraction.
Now given that,
cost of mailing a first-class letter for the first ounce = $0.46
cost of additional ounce or portion of an ounce = $0.20
Since,the weight of letter is x ounces
cost of mailing a first-class letter = $0.2x
Now,Y is the total cost for mailing a letter
Y = 0.46 + 0.2x
Therefore, the cost of mailing a first class letter weighing 2.5 ounces
Y = 0.46 + 0.2*2.5
⇒ Y = 0.46 + 0.5
Y = $0.96
Thus,The cost of mailing a first class letter weighing 2.5 ounces is $0.96

The triangle with vertices at L (-2,5), E ( 1,4), and D(2,-2) is 4 units left, 3 units up, and then reflected over the line y=4 to form the image L'E'D. Which vertex of the image is the greatest distance from the origin?
Answers
Answer:
L'(6,8)
Step-by-step explanation:
If i had to take a guess what i would is subtract 4 from each x number and add 3 to each y number and then reflect over the line y=4 so then that would give me each distance. And by the looks it seems L'(6,8) is the farthest from he origin (0,0)
A rectangular building with a square base is being designed to minimize heat loss. The building designers state that the volume of the building must be exactly 4000 m^3. Write an equation for y, the height of the building, in terms of x, the length and width of the base.
Answers
Answer:
y = 4000/x²
Step-by-step explanation:
The volume of the building is expressed as;
V = x²y where;
x is the length and width of the base.
y is the height of the building
Given
Volume V = 4000m³
Substitute the given volume into the equation as shown;
4000 = x²y
Make y the subject of the formula by dividing both sides by x²
4000/x² = x²y/x²
4000/x² = y
Rearrange
y = 4000/x²
Hence equation for y, the height of the building, in terms of x, the length and width of the base is expressed as y = 4000/x²

What’s quadratic equation
Answers
Answer:
In algebra, a quadratic equation (from the Latin quadratus for "square") is any equation that can be rearranged in standard form as ax^2+bx+c-0 where x represents an unknown, and a, b, and c represent known numbers, where a ≠ 0. If a .0, then the equation is linear, not quadratic, as there is no ax^2 term. The numbers a, b, and c are the coefficients of the equation and may be distinguished by calling them, respectively, the quadratic coefficient, the linear coefficient and the constant or free term.
Step-by-step explanation:
