The coordinates of the point
of the way from A to B are____
The coordinates of the point that is 3 / 10 of the way from point A to point B is C(x, y) = (0.9, - 3).
How to find the coordinates of a point within a line segment
In this problem we find a line segment whose endpoints are known: A(x, y) = (- 3, - 6), B(x, y) = (10, 4), and of which we need to find a point C such that it is 3 / 10 of the way from point A to point B, whose exact location can be found by means of the line segment formula:
C(x, y) = A(x, y) + (3 / 10) · [B(x, y) - A(x, y)]
C(x, y) = (- 3, - 6) + (3 / 10) · [(10, 4) - (- 3, - 6)]
C(x, y) = (- 3, - 6) + (3 / 10) · (13, 10)
C(x, y) = (- 3, - 6) + (3.9, 3)
C(x, y) = (0.9, - 3)
The coordinates of the point that is 3 / 10 of the way from point A to point B is C(x, y) = (0.9, - 3).

A private jet flies the same distance in 7 hours that a commercial jet flies in 5 hours. If the speed of the commercial jet was 99 mph less than 2 times the speed of the
private jet, find the speed of each jet.
Answer
Answer:
Private jet - 165 mphCommercial jet - 231 mphStep-by-step explanation:
Let the speed of the private jet is p and commercial jet is c.
Set equations7p = 5cc = 2p - 99Solve by substitution7p = 5(2p - 99)7p = 10p - 49510p - 7p = 4953p = 495p = 495/3p = 165Find c:

Expressed as a product of its prime factors in index form, a number n is n = 3 times 5 squared times x cubed. express 5n squared as a product of prime factors in index form. give your answer in terms of x.
5n² can be expressed as, 5n² = 3² x 5⁵ x x⁶
Given that n can be written as the product of the primes as
n = 3 x 5² x x³
This expression for n is called the prime factorization of n.
We need to express 5n² as such a product of primes.
For that taking square of n, add the power 2 with the existing powers of 3,5 and x,
So, n² = ( 3 x 5² x x³)² = 3² x 5⁴ x x⁶
So 5n² = 5(3² x 5⁴ x x⁶)
Multiplying 5 with the existing power of 5, 5⁴,
⇒ 5n² = 3² x 5⁵ x x⁶

Consider a cube with an inscribed sphere. The function can be used to find the radius, r, of a sphere given the volume, v. The function can be used to find the side length of the cube, s, depending on the radius of the sphere. The function can be used to find the surface area, a, of the cube. Which is the composed function for the surface area of the cube for any given volume of an inscribed sphere?
The composed function for the surface area of the cube for any given volume of an inscribed sphere, A(V) = 24( [tex]\sqrt[3]{\frac{3V}{4\pi} }[/tex])²
The function used to find the radius r of a sphere given volume V,
r(V) = [tex]\sqrt[3]{\frac{3V}{4\pi} }[/tex]
The function used to find the length of the side s of the cube depending on the radius r of the sphere, s(r) = 2r
The function used to find the surface area A of the cube depending on the side of the cube s, A(s) = 6s²
We need to find the composed function for the surface area A of the cube for any given volume V of an inscribed sphere. i.e., A(V)
We have, A(s) = 6s²
Substituting function for s to A(s)
⇒ A(s(r)) = 6(2r)² = 24r²
Substituting function for r into A(s(r)),
⇒ A(s(r(V))) = 24( [tex]\sqrt[3]{\frac{3V}{4\pi} }[/tex])²

The parking garage charges $3 per hour to park for two hours or less.
The garage charges $3 for each additional hour of parking, up to and
including 5 hours. If a car uses the parking garage for more than 5
hours, there is a flat fee of $20.
Fill in the missing domain values for the following situation.
3x

f(x) = 6 4(x - 2) (Value 2) < r ≤ 5
20
x> (Value 3)
Value 1 =
Value 2 =
Value 3
The function will become:
f ( x ) = 3 x ; 0 ≤ x ≤ 2
f ( x ) = 6 + 4 ( x - 2) for 2 < x ≤ 5
f ( x ) = 20 for x > 5
We are given that:
The parking garage charges $ 3 per hour if the car is parked there for less than 2 hours.
So, we get that:
Parking fees = 3 x for 0 ≤ x ≤ 2
Now, we get that, if the car is parked for more than 2 hours and less than 5 hours, then the parking fee is
6 + 4 ( x - 2) for 2 < x ≤ 5
Now, we are given that it charges a fixed fee of $ 20 if car is parked for more than 5 hours. So, the parking fee will be
20 for x > 5
So, the function becomes:
f ( x ) = 3 x ; 0 ≤ x ≤ 2
f ( x ) = 6 + 4 ( x - 2) for 2 < x ≤ 5
f ( x ) = 20 for x > 5
Therefore, we get that, the function will become:
f ( x ) = 3 x ; 0 ≤ x ≤ 2
f ( x ) = 6 + 4 ( x - 2) for 2 < x ≤ 5
f ( x ) = 20 for x > 5

find the angle between a diagonal of a cube and an adjacent edge. (enter your answer in degrees. round your answer to two decimal places.)
The angle between a diagonal of a cube and an adjacent edge is 54.75°;
Assuming the length of a side of the cube as 1 unit, the three sides are given by the vectors;
a = (1, 0, 0)
b = (0, 1, 0)
c = (0, 0, 1)
The diagonal is given by the vector, v = (1, 1, 1)
The angle between the diagonal and one edge of the cube is given by
cos θ = v. a / |v|.|a|
v. a = (1, 1, 1).(1, 0, 0)
= 1(1) + 1(0) + 1(0
= 1 + 0 + 0
v. a = 1
Magnitude of vector V = √[(1)² + (1)² + (1)²]
|v| = √3
Similarly, |a| = √1;
So, |v|.|a| = √3.√1 = √3
Now, cos θ = 1/√3
So, θ = cos¹(1/√3)
θ = 54.75°
Therefore, the required angle is 54.75°.

The position of the bicyclist at t=8 minutes is 3.2 km
Speed is the rate of change of position of an object in any direction.
position the way in which something or someone is placed or arranged.
when time t = 6 position d = 5
when time t = 5 position d = 2
when time t = 8 position d = x
therefore we can say
