Answer:

Step-by-step explanation:

Since you didn’t specify the type of parabola, I’ll assume it is vertical.

The vertex-form equation of the parabola is

y = a(x-2)² - 9

(5,-18) is a point on the parabola.

-18 = a(5-2)² - 9

-18 = a⋅3² - 9

a = -1

Helen [10]

The value of "x" is 14400 dollars that will make their weekly pay the same

<em><u>Solution:</u></em>

Given that,

<em><u>Brandon is paid $235 per week plus 6% of his total sales in dollars, x, which can be represented by g (x) =235 + 0.06x</u></em>

g(x) = 235 + 0.06x ----- eqn 1

<em><u>Nolan is paid $667 per week plus 3% of his total sales in dollars, x, which can be represented by f(x ) = 667 + 0.03x</u></em>

f(x) = 667 + 0.03x ----------- eqn 2

<em><u>Determine the value of x, in dollars, that will make their weekly pay the same</u></em>

For their weekly pay to be same, g(x) = f(x)

235 + 0.06x = 667 + 0.03x

Move the variables to one side and constants to other side

0.06x - 0.03x = 667 - 235

0.03x = 432

x = 14400

Thus value of "x" is 14400 dollars that will make their weekly pay the same

What is the derivative of 4pi and why?
Diano4ka-milaya [45]
<span>Answer: The derivative of 4pi (4π) is simply zero. In Calculus, the process of differentiation is taking the limit of the given as the change with respect to a certain variable approaches zero. The derivative indicates the slope of a given function, the rate of change with respect to small increments to a reference axis or variable. As our given, 4π, is simply a constant, it does not change with respect to any infinitesimal increment to any variable; thus its derivative is zero.</span>

Determine the simple interest when:
ivann1987 [24]

Answer:

$75.65

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 4.25%/100 = 0.0425 per year,

then, solving our equation

I = 890 × 0.0425 × 2 = 75.65

I = $ 75.65

The simple interest accumulated

on a principal of $ 890.00

at a rate of 4.25% per year

for 2 years is $ 75.65.
