.
Answer:
Answer is A
Step-by-step explanation:
Use the the pythagorean theorem
x=√12²+5²
x=13
Answer:

Step-by-step explanation:
The explicit form for an arithmetic sequence is:

where
is the first term and [ted]d[/tex] is the common difference.
The given sequence is arithmetic because term-previous term is the same per each pair of term and previous term.
That is the following holds:
-4-3=-11-(-4)=-18-(-11)
All of these differences are equal to -7, the common difference.
So let's fill in the explicit form:

The movement of the particle on the circle is its displacement.
The value of dy/dt at this time is -9/2.
<h3>What is the differentiation?</h3>
Differentiation is a process, in Maths, where we find the instantaneous rate of change in function based on one of its variables.
A particle moves on the circle x^2 + y^2=25 in the XY-plane for time t≥0. At the time when the particle is at the point (3,4), dxdt=6.
The equation of the circle is given as:

Differentiate with respect to time

Substitute all the values in the equation

Hence, the value of dy/dt at this time is -9/2.

The discount percent for the given transaction is calculated as; 6.11%
<h3>What is the percentage Discount?</h3>
We are given;
Mark Price; M.P = 4500
Now, formula for discount amount is;
Discount amount = %Discount * M.P
Discount amount = x% * 4500 = 45x
Also;
Selling price is;
S.P = M.P - Discount Amount
S.P = 4500 - 45x
VAT = Vat% * S.P
VAT = (10%*4500) - 45x
VAT = 450 - 45x
S.P with VAT = S.P + VAT Amount = 4500 - 45x + 450 - 45x = 4950 - 90x
Thus;
4950 - 90x = 4400
Solving for x gives;
x = 6.11%
