Answer:

y = -0.07x2 + 3.07x

Step-by-step explanation:

For each plant we add, there is a decrease of 70 grams for all plants from the inicial value of 3 kg of beans.

So, for 2 plants, we have (3 - 0.07) * 2

For 3 plants, we have (3 - 2*0.07) * 3

For x plants, we have (3 - (x-1)*0.07) * x

So we can model the final result of the amount of beans 'y' with the equation:

y = (3 - (x-1)*0.07) * x

y = (3 - 0.07x + 0.07) * x

y = (3.07 - 0.07x) * x

y = -0.07x2 + 3.07x

(In this equation we have a = -0.07, b = 3.07 and c = 0)

Show that point (pi/3,1/2) is on the curve of y=cosx
jarptica [38.1K]
Here y=1/2 x=pi/3=60°

y=cosx
1/2=cos60° and cos60°=1/2
so LHS=RHS

so that point is on curve y=cosx

3 2. Write the equation of a line that includes the point (-4, 0) and has a slope of 5 in slope-intercept form- 12 3 y=-=X-2 5 5
Arturiano [62]

Answer:

y= 5x+20

Step-by-step explanation:

Slope intercept form is

y = mx+b where m is the slope and b is the y intercept

The slope is 5 and a point on the line is (-4,0)

Substituting this information into the equation, we can solve for b

0 = 5(-4) +b

0 = -20+b

Add 20 to each side

0+20 = -20+20+b

20 = b

y = 5x+20

A fair spinner has 9 equal sections: 2 red, 3 blue and 4 green.
Alex17521 [72]

Answer:

The Probability of not getting two consecutive reds is 0.9506

Step-by-step explanation:

Number of sections = 9

Number of red sections = 2

Number of blue sections = 3

Number of green sections = 4

Probability of getting two consecutive reds = \frac{2}{9} \times \frac{2}{9}=\frac{4}{81}

So,The Probability of not getting two consecutive reds =1- \frac{4}{81}=\frac{77}{81}=0.9506

Hence The Probability of not getting two consecutive reds is 0.9506
