The variable d models drone's distance from the safe zone (in meters) t seconds after the drone started flying. D=-5t+4. What is the speed of the drone?
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.
Fatima has a total of $8 to spend to make fruit smoothies. She plans on spending all of the money and will use two types of fruit. Mango cost $0.50 per cup and strawberries cost $1.00 per cup. Write an equation for this situation.
Answer:
0.5x+y= 8---------------1
Step-by-step explanation:
Given data
let the mango be x
and strawberries be y
So the equation for the cost is

Answer:
B = 41.81
Step-by-step explanation:
sin B = opposite/ hyp
sin B = 2/3
Take the inverse sin of each side
sin ^-1 sin (B) =sin ^-1 (2/3)
B =41.8103149
To the nearest hundredth
B = 41.81

A car is traveling with a velocity of 65.0 km/h. In the next 15 minutes the car gradually slows down at the end of the 15 minutes the car is traveling at 45.0 km/h what is the average acceleration of the car during the time it slows down?
Answer:
- 0.006173 m/s²
Step-by-step explanation:
Given :
Initial Velocity, u = 65km/hr = (65*1000) / 3600 = 18.056 m/s
Final velocity, v = 45 km/ hr = (45*1000) / 3600 = 12.5 m/s
Time at which change in velocity occurred = 15 minutes = 15 * 60 = 900 s
Acceleration = Change in velocity with time
Acceleration = (v - u) / t
Acceleration = (12.5 - 18.056) / 900
Acceleration (deceleration) = - 5.556 / 900
Deceleration = - 0.006173 m/s²

Write the word sentence as an inequality. Then solve the inequality. Six times a number x is at least −24. An inequality is________ . The solution of this inequality is _________.
Answer:
6x ≥ -24
An inequality is "a statement of an order relationship—greater than, greater than or equal to, less than, or less than or equal to—between two numbers or algebraic expressions."
The solution to this inequality is:
x ≥ -4
Step-by-step explanation:
There's no explanation needed.
I just converted the words into an equation, then solved it by dividing both sides by 6. I looked up the definition of an inequality and pasted it here.

the table shows for a quadratic function.
what is the average rate of change for this function for the interval from from x=3 to x=5
Answer:
the average rate of change is 12
Step-by-step explanation:
The computation of the average rate of change is shown below:
As from the attached table
f(b) = f(5) = 32
f(a) = f(3) = 8
Now the average rate of change is
= (32 - 8) ÷ ( 5 - 3)
= (24 ÷ 2)
= 12
Therefore the average rate of change is 12
So the same is relevant and considered too

x = −3.5
If you solve the equationx - 3 = 7, what information will you have?
Answer:
x=4
Step-by-step explanation:
both sides, add 7
Hey there!
“x – 3 = 7”
• FIRST: ADD by 3 on BOTH sides
• x – 3 + 3 = 7 + 3
• CANCEL out: –3 + 3 because that gives you 0
• KEEP: 7 + 3 because that helps us solve for your x-value
• NEW EQUATION: x = 7 + 3
• FLIP THE EQUATION: 7 + 3 = x
“Solve above and you have your answer!”
• ANSWER: x = 10 ☑️
Good luck on your assignment and enjoy your day!

Step-by-step explanation:
given logx 2=p and logx 7=q , express log7 4x³ in terms of p and q.
Answer: (2*p + 3)/q
Step-by-step explanation:
First, let's remember the relationships:
Logₙ(a) = Ln(a)/Ln(n)
Ln(A*B) = Ln(A) + Ln(B)
Ln(a^n) = n*Ln(a)
Now, we know that:
Logₓ(2) = p
Logₓ(7) = q
We want to express:
Log₇(4*x^3) in terms of p and q.
First, we can rewrite the first two relations as:
Ln(2)/Ln(x) = p
Ln(7)/ln(x) = q
then we have:
Ln(2) = p*Ln(x)
Ln(7) = q*Ln(x)
Ok:
Now let's play with our equation:
Log₇(4*x^3)
First, this is equal to:
Ln(4*x^3)/Ln(7)
We now can rewrite this as:
(Ln(4) + Ln(x^3))/Ln(7)
= (Ln(2^2) + Ln(x^3))/Ln(7)
= (2*Ln(2) + 3*Ln(x))/Ln(7)
Now we can replace Ln(2) by p*Ln(x) and Ln(7) by q*Ln(x)
(2*p*Ln(x) + 3*Ln(x))/(q*Ln(x)) = (2*p + 3)/q
This is the expression we wanted.

Here are two similar rectangles.
1 cm
2 cm
4 cm
Work out the area of the larger rectangle.
Answer:
8cm^2
Step-by-step explanation:
4*2=8
The area of the larger rectangle will be 8 cm.
What is the area of the rectangle?The space occupied by any two-dimensional figure in a plane is called the area. The space occupied by the rectangle in a two-dimensional plane is called the area of the rectangle.
Given that the sides of the small rectangle are 1cm and 2cm. One side of the larger rectangle is 4cm so the other side will be 2cm.
The area of the rectangle is calculated by using the formula below:-
Area = 4 x 2
Area = 8 cm
Therefore, the area of the larger rectangle will be 8 cm.
