Answer:
9674.28 miles
Step-by-step explanation:
From the above question, we are given:
Central angle = 140°
Radius = 3960 miles
We are to solve for the distance = Arc length
The formula for Arc length when your central angle is in radians
r × θ
θ = 140°
Converting 140° to radians
140° × π/180 = 2.443rad
Hence,
3960 × 2.443 rad
= 9674.28 miles
The ship would travel 9674.28 miles.

1. A construction worker was preparing wood for a project.
He had 1/4 of a meter of wood that he needed to cut
into equal size pieces. If he cut the wood into 6 pieces,
how long will each piece be?
Answer:
4.17 cm
Step-by-step explanation:
I took 1m=100cm
Then divided the cm by 4 to get the 1/4 of a meter which is 25
25/6 is 4.16repeating so I rounded it up to 4.17.
If your teacher wants it in a fraction I would state it as 25/6 cm

Answer:
240 cm^3
Step-by-step explanation:
The solid is composed by two rectangular parallelepipeds. To find the total volume we have to find the volume of the two solids and added up.
To find the volume of a parallelepiped we have to use this formula:
V = base surface x height
The area of rectangle is : base x width
So:
Area first rectangle: 4 x 6 = 24 cm^2
V = 24 x 7 = 168 cm^3
Area second rectangle: 4 x 2 = 8 cm^2
V = 8 x 9 = 72 cm^3
total volume = 168 + 72 = 240 cm^3
9. The height of a ball thrown into the air is a quadratic function
of time. The ball is thrown from a height of 6 ft above the
ground. After 1 second, the ball reaches its maximum height of
22 ft above the ground. Write the equation of the function in
vertex form.
Answer:f(x)=-16(x-1)^2+22
Step-by-step explanation:
The equation for the trajectory of ball in the air is h(t) = -16t² + 32t + 6.
What is differentiation?The differentiation of a function is defined as rate of change of its value at a point. It can be written as f'(x) = lim h --> 0 (f(x + h) - f(x)) /(x + h - x).
It can also be said as the slope of the tangent for the function at a given point.
Given that,
The maximum height reached by the ball after 1 sec is 22 ft above ground.
And, the height at which it is thrown is 6 ft above the ground.
Which implies at 0 sec the height is 6 ft.
The quadratic function for the height can be written as,
h(t) = at² + bt + c
Substitute t = 0 to gat,
f(0) = a × 0² + b × 0 + c
=> c = 6
Now, for maximum height,
h'(t) = 0
=> 2at + b = 0
At maximum height t = 1
Then, the above expression becomes,
2a × 1 + b = 0
=> a = -b/2
Substitute t = 1 in h(t) = at² + bt + c to get,
22 = a + b + c
=> 22 = -b/2 + b + 6
=> b/2 = 16
=> b = 32
Then, a = -b/2
= -32/2
=-16
Thus substituting the corresponding values the equation can be written as h(t) = -16t² + 32t + 6.
Hence, the required equation for the path of the ball in the air is h(t) = -16t² + 32t + 6.

Which of the following pairs of functions are inverses of each other?
Answer:
THE ANSWER IS B
Step-by-step explanation:
IT JUST MAKES SENSE TO CHOOSE B
The option D pairs of functions are inverses of each other.
What is the function?A relationship between a group of inputs and one output is referred to as a function. In plain English, a function is an association between inputs in which each input is connected to precisely one output. A domain, codomain, or range exists for every function. Typically, f(x), where x is the input, is used to represent a function.
To find the inverse of a function, write the function f(x) as a function of x and then solve for x as a function of f(x).
For option A,
f(x) = 2 + ∛x
To solve for x,
∛x = f(x) - 2
x = (f(x) - 2)³
That is also the inverse So,
g(x) = (x -2)³ "Not correct"
For Option B,
f(x) = x/6 + 8
To solve for x,
x/6 = f(x) -8
x = 6f(x) - 6 *8
That is also the inverse So,
g(x) = 6x - 6 *8 "Not correct"
For Option C,
f(x) = 7/x - 9
To solve for x,
7/x = f(x) +9
x = [tex]\frac{7}{f(x) +9}[/tex]
That is also the inverse So,
g(x) = [tex]\frac{7}{x +9}[/tex] "Not correct"
For Option D,
f(x) = 5x - 11
To solve for x,
5x= f(x) + 11
x = (f(x) + 11)/5
That is also the inverse So,
g(x) =(x + 11)/5 "correct"
Thus, the option D pairs of functions are inverses of each other.

The sum to infinity of a geometric series is 4 and the second term is 1. Find the first,third and fourth terms.
Answer:
2, 0.5 and 0.25.
Step-by-step explanation:
The nth term an = a1r^(n-1) where a1 = first term and r = the common ratio.
The sum to infinity = a1/(1-r) for -1 < r < 1.
So we have:
Second term a2 = 1 = a1(r)(2-1) = a1r and
4 = a1/(1 - r)
From the first equation:
a1 =1/r
So substituting in the second equation:
4 = 1/ r / (1 - r)
4 = 1 / r - r^2
4r - 4r^2 = 1
4r^2 - 4r + 1 = 0
(2r - 1)(2r - 1) = 0
r = 0.5
So the first term a1 = 1/ r =1/0.5 = 2.
The third = 1*0.5 = 0.5
and the 4th = 0.5*0.5 = 0.25.

how do you solve 2x+4y=7 and -2x +3y=14
Answer:
y=3 x= -5/2
Step-by-step explanation:
simultaneous equations
2x + 4y = 7 ------ eq 1
-2x + 3y = 14 --------eq2
(different signs add)
(eq 2 + eq 1)
-2x +(-2x) = 0
4y+3y = 7y
7+14 = 21
7y= 21
(divide both sides by 7)
y= 21/7= 3
2x + 4(3) = 7
2x+ 12=7
2x = 7-12
2x = -5
x= -5/2
