Sara's mom takes the parkway to work. It takes her 30 minutes to travel from mile marker 88 where she enters to her exit at mile marker 121. What is her average speed
Sara's mom average speed is 66mph. The next step is to divide the distance by the time: 33/0.5 = 66 mph.
What is average speed ?You may estimate the average pace at which an object will go a distance by looking at its average speed. Average speed is calculated by dividing a quantity by the time required to obtain that quantity.
Finding the distance and the time is necessary to calculate speed.
In this situation, you must deduct mile marker 88 from 121 to determine the distance.
121 - 88 = 33mile
Even though the time is 30 minutes, you're probably interested in miles per hour. 30 minutes must be converted to 0.5 hours.
The next step is to divide the distance by the time: 33/0.5 = 66 mph.

f(x) = 3x³ - 17x² - kx + 18? Justify your answer.
Answer:
k = 9
Step-by-step explanation:
According to the Factor theorem, if (x - a) is a factor of f(x) then f(a) = 0
given (x - 6) is a factor of f(x) then f(6) = 0 , that is
3(6)³ - 17(6)² - 6k + 18 = 0
3(216) - 17(36) - 6k + 18 = 0
648 - 612 - 6k + 18 = 0
36 - 6k + 18 = 0
54 - 6k = 0 ( subtract 54 from both sides )
- 6k = - 54 ( divide both sides by - 6 )
k = 9

What is circumference?
The circumference of a circle or ellipse in geometry is its perimeter. That is, if the circle were opened up and straightened out to a line segment, the circumference would be the length of the arc. The curve length around any closed figure is more generally referred to as the perimeter.
Given:
Pia drew a circle with a circumference of C and a diameter of 14 in
We have to find the circumference of the circle.
Since,
Circumference = 2*π*r
Here
Diameter of circle = 14 in.
⇒ Radius of circle = 7 in.
⇒ Circumference = 2*π*7 = 43.98 in.
Hence, the circumference of the circle is 43.98 in.

In altitude BH and angle bisector AL intersect at point M. Given m∠HML = 100° and m∠MLC = 110°. Find angles of △ABC
The angles of triangle ABC are 60 degrees when altitude BH and bisector AL intersect at point M.
What is equilateral triangle?
An equilateral triangle in geometry is a triangle with equal-length sides on all three sides.
Given that:
[tex]\angle HML = 100 \\\\\angle MLC = 110[/tex]
Since, BH is the altitude [tex]\angle MHC= 90[/tex].
The total angle of a quadrilateral is 360, hence:

C = 60 degrees.
Now consider triangle BHC:
The sum of angle of a triangle is 180, hence:
90 + 60 + B = 180

Answer:
➜ ∠4 = ∠2

➜ ∠1 = ∠3
Step-by-step explanation:
We can use vertical angles to prove the first statement true, ∠4 = ∠2.
Next, ∠2 and ∠3 are supplementary angles, so if you add them together you will get 180 degrees. This statement is also true.
Then, ∠1 and ∠2 are not complimentary angles. This statement is false.
Lastly, we can use the same reasoning of the first one to prove this statement true as well. They are vertical angles, ∠1 = ∠3.

(b) 2. 5 hour
If a train travels 283. 8km in 4. 4 hours, the train travels 71km in 1 hour and the train travels 114.5km in 2.5 hours.
Based on the assumption that the train is traveling at a constant speed throughout its journey.
To find the speed the train travels , we divide the total distance by the total time:
speed = 283.8km/ 4.4 hours
speed = 64.5 km/h
To find the distance the train travels , we multiply the speed of the train by the total time:
Distance travelled in 1 hour = 64.5 km/ hour × 1 hour
Distance travelled in 1 hour = 64.5 km
Distance travelled in 2.5 hours = 64.5 km/hour x 2.5 hours

The value of the composite function [f(g(f(f(f(g(27))))))], when f(x) = log₃(x) and g(x) = 3ˣ is 1
How to evaluate the composite functionFrom the question, we have the following parameters that can be used in our computation:
Let f(x) = log base 3 of x and g(x) = 3^x.
Express the equations properly
So, we have the following representations
f(x) = log₃(x) and g(x) = 3ˣ
Calculating the composite function [f(g(f(f(f(g(27))))))], we have
[f(g(f(f(f(g(27))))))] = [f(g(f(f(f(3²⁷))))))]
Next, we have:
[f(g(f(f(f(g(27))))))] = [f(g(f(f(log₃(3²⁷))))))]
This gives
[f(g(f(f(f(g(27))))))] = [f(g(f(f(27))))))]
For f(27), we have
[f(g(f(f(f(g(27))))))] = [f(g(f(3)))))]
For f(3), we have
[f(g(f(f(f(g(27))))))] = [f(g(1))))]
Calculating g(1), we have
[f(g(f(f(f(g(27))))))] = f(3)
Lastly, we have
[f(g(f(f(f(g(27))))))] = log₃(3)

[f(g(f(f(f(g(27))))))] = 1
