Find g'​(t) for the function ​g(t) = 7/t^4
Alex17521 [72]

The differentiation of the function g(t) = 7/t⁴ will be equal to g¹(t)=-28/t⁵

<h3>What is differentiation?</h3>

The method of determining the derivative, or rate of change, of a function in mathematics.is termed as the differentiation.

Given that:-

g(t)= \dfrac{7}{t^4}

The derivative will be calculated as:-

g'(t)=7   \dfrac{d}{dt}(t^{-4})\\\\\\g'(t)=7\times (-4t^{-5})\\\\\\g'(t)=\dfrac{-28}{t^5}

Therefore the differentiation of the function g(t) = 7/t⁴ will be equal to g¹(t)=-28/t⁵

Each of 16 store cashiers worked an average of 21 hours per week and are paid $8.25 per hour. After the store manager hires 2 ad
Pachacha [2.7K]

Answer:

<u>$211.50</u>

Step-by-step explanation:

Initially:

21 hours per week at 8.25 per hours means:

21 * 8.25 = 173.25 dollars per person

16 person = 16 * 173.25 = $2772 (total)

2nd phase:

2 more cashier = 16 + 2 = 18 cashiers

Per hour 0.25 more, so 8.25 + 0.25 = $8.50 per hour

1.5 hrs less than 21, so 21 - 1.5 = 19.5 hours

Hence,

18 * 19.5 * 8.50 = $2983.50 (new total)

Change in money paid = 2983.50 - 2772 = $211.50

What is the slope of a line parallel to the line whose equation is 5x+y=-9
Rzqust [24]

Answer:

slope = - 5

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c (m is the slope and c the y- intercept )

Given

5x + y = - 9 ( subtract 5x from both sides )

y = - 5x - 9 ← in slope- intercept form

with slope m = - 5

Parallel lines have equal slopes, thus

The slope of a parallel line to the given equation is m = - 5
