Answer:
it has to be a or d
Step-by-step explanation:
they have 4000 in 1996 but we want 1991.so we get 15 percent of least time but i belive its d
Answer:
A rectangular equation, or an equation in rectangular form is an equation composed of variables like x and y which can be graphed on a regular Cartesian plane.
Parametric equations are a set of equations that express a set of quantities as explicit functions of a number of independent variables, known as "parameters." For example, while the equation of a circle in Cartesian coordinates can be given by r^2=x^2+y^2, one set of parametric equations for the circle are given by
x=r cost
y=r sin
Note that parametric representations are generally nonunique, so the same quantities may be expressed by a number of different parameterizations. A single parameter is usually represented with the parameter t, while the symbols u and v are commonly used for parametric equations in two parameters.Parametric equations provide a convenient way to represent curves and surfaces, as implemented, for example, in the Wolfram Language commands ParametricPlot[{x, y}, {t, t1, t2}] and ParametricPlot3D[{x, y, z}, {u, u1, u2}, {v, v1, v2}]. Unsurprisingly, curves and surfaces obtained by way of parametric equation representations are known as parametric curves and parametric surfaces, respectively.
Also if you dont know how to graph them you can Use DESMOS graphing calculator
Answer:
So, Time taken to make 120 tarts is 2.5 hour
Step-by-step explanation:
We are given
Rovan can make 48 tarts per hour
rate of making tarts = 48 tarts / hour
we have to find time
total number of tarts =120
Total time = ( Total number of tarts)/( rate of making tarts)
now, we can plug value
and we get
So, Time taken to make 120 tarts is 2.5 hour
Given:
A credit card advertises an annual interest rate of 23%.
To find:
The equivalent monthly interest rate.
Solution:
We know that,
1 year = 12 months
It is given that, the credit card advertises an annual interest rate of 23%. So, the equivalent monthly interest rate is:
Therefore, the equivalent monthly interest rate is 
and the approximate equivalent monthly interest rate is 1.9167%.
