Given:
The function is:
[tex]y=5500\ln (9t+4)[/tex]
Where y is the sales of lawn mowers t years after a particular model is introduced.
To find:
How many mowers will be sold 3 years after a model is introduced?
Solution:
We have,
[tex]y=5500\ln (9t+4)[/tex]
Substituting [tex]t=3[/tex], we get
[tex]y=5500\ln (9(3)+4)[/tex]
[tex]y=5500\ln (27+4)[/tex]
[tex]y=5500\ln (31)[/tex]
On substituting the approximate value of ln(31), we get
[tex]y=5500\times 3.433987[/tex]
[tex]y=18886.9285[/tex]
[tex]y\approx 18887[/tex]
Therefore, the 18887 mowers will be sold 3 years after a model is introduced.

A=ah+bh+ch+1
2﹣a4+2(ab)2+2(ac)2﹣b4+2(bc)2﹣c4=3·8+4·8+5·8+1
2·﹣34+2·(3·4)2+2·(3·5)2﹣44+2·(4·5)2﹣54
= 108
10.
A=ah+bh+ch+1
2﹣a4+2(ab)2+2(ac)2﹣b4+2(bc)2﹣c4=15·24+8·24+17·24+1

Without looking, Tammy takes a marble out of a bag that contains 10 red marbles, 15 green marbles, and 25 blue marbles. She records its color and returns the marble to the bag. If Tammy repeats this process 90 times, how many times can she expect to pull out a red marble?
Answer:
18 is the answer
Step-by-step explanation:
added all the marbles she took out to see the total she took out which was 50
if she did it 90 times I need to see how much time 50 she did it more and that was so 90 divided by 50 is 1.8 and that times 10
(times because we want to see how many times the red marble would come out) and that’s 18
hope this helps u

solve the equation for x
2/3x-1/9x+5=20
Answer:
x=27
Step-by-step explanation:
You want to isolate the variables so you subtract 5 from both sides. Therefore the equation will be 2/3x-1/9x=15. You want to take away the fraction because no one likes fractions. You have to multiply everything by 9. Therefore, the equation will be 6x-x=135. 5x=135. You want to isolate x so you have to divide each side by 5. x=135/5. Simplify to get x=27.

Given circle Q a measure of SR = 120 degree and a radius of 9 feet, as shown below determine the arc length of SR use mathematics to explain how you determined your answer. 
Volume and circles
Help please ❤️
Answer:
Arc length SR = 18.85 ft
Step-by-step explanation:
To get the arc length, we use the formula below
theta/360 * 2 * pi * r
theta is the central angle subtended by the arc which is 120 degrees
r is the radius of the circle which is 9 ft
Substituting these values, we have
120/360 * 2 * 3.142 * 9
= 18.85 ft

Juan rides the bus to school each day. He always arrives at his bus stop on time, but his bus is late 80% of the time. Juan runs a simulation to model this using a random number generator. He assigns these digits to the possible outcomes for each day of the week:
• Let 0 and 1 = bus is on time
• Let 2, 3, 4, 5, 6, 7, 8, and 9 = bus is late
The table shows the results of the simulation.

Find the standard form of the equation of the parabola with the given characteristics. Vertex: (-6, 1); focus: (-6, 0)
Answer: [tex](x+6)^2=-4(y-1)[/tex]
Step-by-step explanation:
Given
Vertex of the parabola [tex](-6,1)[/tex]
Focus of the parabola [tex](-6,0)[/tex]
As the x coordinate of vertex and focus is same and focus lie below the vertex, therefore the parabola is the type of
[tex](x+6)^2=-4a(y-1)[/tex]
distance between Vertex and focus is 1 unit
[tex]\therefore a=1[/tex]
Parabola becomes
[tex]\Rightarrow (x+6)^2=-4(y-1)[/tex]
