Answer: it will take them 2.22 hours working together.

Step-by-step explanation:

It takes Destiny y 4 hours to file all the daily paperwork. This means that unit rate of Destiny would be

1/4 per hour.

It takes Susan 5 hours to file the same paperwork. This means that unit rate of Susan would be

1/5 per hour.

If they work together, they would work at their own individual rates. This means that their individual rates are additive.

Let t represent the time it will take them if they worked together. Since their combined rate is additive Therefore,

1/4 + 1/5 = 1/t

9/20 = 1/t

t = 20/9 = 2.22 hours

Taylor graphs the system below on her graphing calculator and decides that f(x)=g(x) at x=0, x=1, and x=3. Provide Taylor some f
goblinko [34]

Answer:

f(x)=g(x) at x= 0 and x= 1 and not at x= 3.

Step-by-step explanation:

We have the functions, f(x)=2x+1 and g(x)=2x^2+1.

It is given that,

At x=0, x=1, and x=3, f(x)=g(x)

i.e. 2x+1=2x^2+1

i.e. 2x^2-2x=0

i.e. 2x(x-1)=0

i.e. x= 0 and (x-1)= 0

i.e. x= 0 and x= 1.

Also, after plotting the graphs of both the functions, we see their intersection point are (0,1) and (1,3).

Thus, we get that f(x)=g(x) at x= 0 and x= 1 and not at x= 3.

Sin97°cos43°+cos97°sin43°
kirza4 [7]
I added a screenshot with the head of the question

Answer:
sin (140°)

Explanation:
Angle addition formulas are used to express the trigonometric function in terms of the sum/difference between two angles α and β
These rules are shown in the attached image.

Now, the given expression is::
sin97°cos43°+cos97°sin43°We have:
α = 97°
β = 43°

Comparing the given formula with the general formulas in the image, we would find that the given formula represents the sum of the sin of two angles.

Therefore:
sin97°cos43°+cos97°sin43° 
= sin (97°+43°)
= sin (140°)

Hope this helps :)
