Create three fractions whose product is -5/24. You may only use fractions between -8/9 to 8/9 and you can only use a fraction on
damaskus [11]

Answer:

We find 3/4-5/24 = 0.54166666666 and try 2/7 x 6/8 = 0.21428571428

this is 0.069 too much we look at this as a fraction = 0.07 which is 1/10 approx of the 6/8. we then reapply 7/9 x 2/7 x 3/3 = 0.2

So we went up by 1 and can show another

2/7 x 7/10 = 2.0

So to 1dp there is lots of fractions including 2/7 x 7/9 = 2.0

But for three fractions that multiply together we can chose 5/7 x 2/6 x 6/6 = 2.0  As 5 x 2 x 6 = 60 and 60/360-102 = 60/258 = 0.20 and divided 198 =numbers 8 and 1/3 work with = 1.98/8.3 = 2.38554

We try again 1.68/8.3 = -0.2024 = 2/8 x 8/10 = 0.2

The balance is 1.3/2 x 0.8/2 = 0.65 x 0.333 = 13/20 x 1/3

3/5 x 1/3 = 0.2

Answer:10%= 310

5%= 155

15%=465

Step-by-step explanation: Solution for what is 15% of 3100

3100/x=100/15

(3100/x)*x=(100/15)*x       - we multiply both sides of the equation by x

3100=6.66666666667*x       - we divide both sides of the equation by (6.66666666667) to get x

3100/6.66666666667=x

465=x

x=465

Let f(x) = xe^-x+ ce^-x, where c is a positive constant. For what positive value of c does f have an absolute
Illusion [34]

Answer:

c=6

Step-by-step explanation:

The absolute maximum of a continuous function f(x) is where f'(x)=0. Therefore, we must differentiate the function and then set x=-5 and f'(x)=0 to determine the value of c:

f(x)=xe^{-x}+ce^{-x}

f'(x)=-xe^{-x}+e^{-x}-ce^{-x}

0=-(-5)e^{-(-5)}+e^{-(-5)}-ce^{-(-5)}

0=5e^{5}+e^{5}-ce^{5}

0=e^5(5+1-c)

0=6-c

c=6

Therefore, when c=6, the absolute maximum of the function is x=-5.

I've attached a graph to help you visually see this.

PilotLPTM [1.2K]
A] From the graph, there is strong correlation between the satisfaction score and salary, this is implied by the closeness of the points on the graph.
b] Given that Hilda use the function y=0.0005x +60 to model the relationship, the score for $65000 will be given as follows;
y=0.0005(65000)+60
y=92.5
The number 0.0005 shows the rate of change of job satisfaction with salary
