Answer:
v = 5 m/s
Step-by-step explanation:
The variable d models drone's distance from the safe zone (in meters) t seconds after the drone started flying is :
d = -5t+4
We need to find the speed of the drone. Speed is the rate of change of position.
[tex]v=\dfrac{dd}{dt}\\\\=\dfrac{d}{dt}(-5t+4)\\\\v=-5\ m/s[/tex]
Hence, the speed of the drone is 5 m/s.

Use the Zero Product Property to find the x-intercepts for y=3x2−7x+4
Answer:
x = [tex]\frac{4}{3}[/tex], x = 1
Step-by-step explanation:
To find the x- intercepts, let y = 0 , that is
3x² - 7x + 4 = 0
Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.
product = 3 × 4 = 12 and sum = - 7
The factors are - 3 and - 4
Use these factors to split the x- term
3x² - 3x - 4x + 4 = 0 ( factor the first/second and third/fourth terms )
3x(x - 1) - 4(x - 1) = 0 ← factor out (x - 1) from each term
(x - 1)(3x - 4) = 0
Equate each factor to zero and solve for x
x - 1 = 0 ⇒ x = 1
3x - 4 = 0 ⇒ 3x = 4 ⇒ x = [tex]\frac{4}{3}[/tex]
x- intercepts are x = [tex]\frac{4}{3}[/tex] , x = 1
([tex]\frac{4}{3}[/tex], 0 ), (1, 0 ) ← in coordinate form
A system of equations has 1 solution. If 4x – y = 5 is one of the equations, which could be the other equation?

For fx), evaluate the following:
a. (0)
b. (6)
Answer:
a. f(0) = 4
b. f(6) = 8
Step-by-step explanation:
Let us solve the question
∵ f(x) = x + 4 if x < 5 ⇒ First part
→ That means if x less then 5 we will use this part of f(x)
∵ f(x) = 8 if 5 ≤ x < 7 ⇒ Second part
→ That means if x = 5 or greater than 5 and less than 7, we will use
this part of f(x)
∵ f(x) = 2x - 1 if 7 ≤ x ≤ 10 ⇒ Third part
→ That means if x equal 7 or greater than 7 and less than 10 or equal 10,
we will use this part of f(x)
a. The value of f(0)
∵ x = 0
∵ 0 < 5
→ That means we will use the first part of f(x)
∵ f(x) = x + 4
∴ f(0) = 0 + 4
∴ f(0) = 4
b. The value of f(6)
∵ x = 6
∵ 6 is between 5 and 7
→ That means we will use the second part of f(x)
∵ f(x) = 8
→ It means the value of f(x) is 8 for any values of x from 5 to less than 7
∴ f(6) = 8

A committee must be formed with 4 teachers and 5 students. If there are 7 teachers to choose from, and 15 students, how many different ways could the committee be made?
Answer:
Step-by-step explanation:
There are a total of 10 persons (6 teachers + 4 students) from which a committee of 5 is to be formed. This can be done in 10C5 ways.
The number of ways that a committee can be formed with no students in it is to select 5 teachers out of the pool of 6 teachers available. This can be done in 6C5 ways.
Therefore the total number of ways that the committee can be formed with at least one student in it is 10C5 - 6C5.
10C5 = 252
6C5 = 6
Therefore the required number of ways = 246
The time required for a trip of a certain distance in a car varies indirectly as the rate the car travels. A trip took 18 hours traveling at 50 miles per hour. How long would this trip take if the car was traveling at 75 miles per hour?
Answer:
The answer is 12.
Step-by-step explanation:
If you multiply 18 by 50, you would get how long the trip is, which is 900 miles. Then, divide 900 by 75, you would then get the answer of 12. The trip would take 12 hours at 75 mph.
A parking garage charges $5 for the first hour, $10 for up to 2 hours, and $12 for the entire day. Let G be the dollar cost of parking for t hours
Answer:
Cost is G for t hours =[tex]\left \{ {5t for{t=0 <t<2} \atop 12 for{t >2}} \right.[/tex]
Step-by-step explanation:
According to question parking garage takes
5$ for 0 to 1hr
10$ for 0 to 2hr and
12$ for 0 to 24hr
Let t be the time for which car is parked in garage and the total cost is G then
G =[tex]\left \{ {5t for{t=0 <t<2} \atop 12 for{t >2}} \right.[/tex]
therefore cost is G =[tex]\left \{ {5t for{t=0 <t<2} \atop 12 for{t >2}} \right.[/tex]
The cost of parking a car for 5 hours is required.
Cost of 5 hours will be $25.
The cost of parking for each hour = $5
The cost of parking for entire day = $120
Let [tex]t[/tex] be the number of hours
[tex]G[/tex] be the total cost.
The function will be
[tex]G(t)=5t[/tex]
The cost at 5 hours will be
[tex]G(5)=5\times 5=25[/tex]
So, cost of 5 hours will be $25.
