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.

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
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

What is the slope of the following line: 2y-4x=-16
Answer:
The slope is 2
Step-by-step explanation:
So convert the equation into point slope form
y=mx+b
Isolate the 2y by adding 4x to both sides using inverse operations
2y=-16+4x
now divide 2 on both sides to make y isolated
y=-8+2x
Now convert
y=2x-8
the slope is 2

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

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.
Tom simplified an expression in three steps, as shown: x to the power of negative 2 multiplied by y to the power of 4, over y multiplied by x to the power of 4 multiplied by x to the power of 4 multiplied by y to the power of negative 2, the whole to the power of 4 equal to x to the power of 2 multiplied by y to the power of 8, over y to the power of 4 multiplied by x to the power of 8 multiplied by x to the power of 8 multiplied by y to the power of 2 equal to x to the power of 2 multiplied by y to the power of 8, over y to the power of 6 multiplied by x to the power of 16. Which is the first incorrect step and why? (5 points) Step 1, all the exponents are increased by 4 Step 2, the exponents of the same base are added during multiplication Step 3, the exponents of the same base are subtracted during division Step 3, all the exponents are added during division
Answer:
Step 1, all the exponents are increased by 4Step-by-step explanation:
The three steps are
(x⁻² × y⁴ /y × x⁴ × x⁴ × y⁻²)⁴ = x²×y⁸/y⁴×x⁸×x⁸×y² =x²×y⁸/y⁶×x¹⁶Correct solution should be:
(x⁻² × y⁴ /y × x⁴ × x⁴ × y⁻²)⁴ = all powers inside the parenthesis should be multiplied by 4 as per power of the power (xᵃ)ᵇ = xᵃᵇThis would give next steps:
x⁻⁸×y¹⁶/y⁴×x⁸×x⁸×y⁻⁸ =x⁻⁸×y¹⁶/x¹⁶×y⁻⁴ =y²⁰/x²⁴Answer options:
Step 1, all the exponents are increased by 4
There should be multiplication of powers. (It is close option but is not fully correct as not all the exponents increased by 4, for example y became y⁴)Step 2, the exponents of the same base are added during multiplication
It was done correctlyStep 3 wasn't performed yet, there was step 1 and 2.
So answers about step 3 are irrelevantAnswer:
It would be number 3.

Instructions: Find the measurement of the diagonal indicated in the following parallelogram. Please help :)
Answer:
ZD = 10
Step-by-step explanation:
In a parallelogram
Every two opposite sides are parallelEvery two opposite sides are equalEvery two opposite angles are equalEvery two adjacent angles are supplementaryThe two diagonals bisect each other (meet each other at their midpoint)Let us solve the question
∵ ABCD is a parallelogram
∵ AC and DB are its diagonals
→ By using the 5th property above
∴ AC and BD bisect each other
∵ AC ∩ BD at point Z
→ That means Z is the midpoint of them
∴ Z is the midpoint of BD
→ That means Z divides BD into 2 equal parts BZ and ZD
∴ BZ = ZD
∵ BZ = 10
∴ ZD = 10

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.

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.

The perimeter of a rectangle is 24 inches. If the length of
the rectangle is less than the width of the
rectangle, which of the following best illustrates the
domain for the length of this rectangle?
Answer:
Option B
Step-by-step explanation:
Let the length of the rectangle = l inches
And width of the rectangle = w inches
Perimeter = 2(l + w) = 24 inches
(l + w) = 12
w = 12 - l --------(1)
Length of the rectangle is less than the width,
l < w
By substituting the value of w from equation (1),
l < 12 - l
2l < 12
l < 6
Since, length of the rectangle will be greater than zero,
l > 0
Inequality that best illustrate the domain of the length will be,
0 < l < 6
Option (B) will be the answer.

find the values of y for which the distance between the point p2,-3 and q 10, y is 10 units
Answer:
y = - 9, y = 3
Step-by-step explanation:
Calculate distance d using the distance formula
d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]
with (x₁, y₁ ) = (2, - 3) and (x₂, y₂ ) = (10, y)
d = [tex]\sqrt{(10-2)^2+(y+3)^2}[/tex]
= [tex]\sqrt{8^2+(y+3)^2}[/tex]
Given distance between points is 10, then
[tex]\sqrt{64 +(y+3)^2}[/tex] = 10 ( square both sides )
64 + (y + 3)² = 100 ( subtract 64 from both sides )
(y + 3)² = 36 ( take the square root of both sides )
y + 3 = ± [tex]\sqrt{36}[/tex] = ± 6 ( subtract 3 from both sides )
y = - 3 ± 6 , thus
y = - 3 - 6 = - 9
y = - 3 + 6 = 3
