2. During typhoon Ambo, PAGASA tracks the amount of accumulating rainfall. For the first three hours of typhoon, the rain fell at a constant rate of 25mm per hour The typhoon slows down for an hour and started again at a constant rate of 20 mm per hour for the next two hours. Write a piecewise function that models the amount of rainfall as function of time.
Answers
Answer:
Kindly check explanation
Step-by-step explanation:
Given the following information:
First three hours of typhoon: rate of Rainfall. = 25mm per hour
Typhoon slows down for an hour : then Rainfall began again at a constant rate of 20 mm per hour for the next 2 hours
Piecewise function which models Rainfall ad a function of time
Amount of Rainfall as a function of time = f(t)
f(t) = 25t ; if t≤ 3
When typhoon slowed down for an hour :
f(t) = 0;
f(t) = 25*3 ; for t ∈ (3, 4)
Then Rainfall at a constant rate of 20mm for another 2 hours
f(t) = (25 *3) + 20(t - 4) ; for t ∈ (5, 6)

Determine the area under the standard normal curve that lies to the right of the z-score of 1.44. (Use a four-digit decimal. No rounding necessary.)
Answers
Answer:
The area is 0.0749
Step-by-step explanation:
The area under the standard normal curve represents probability and has a total value of 1
Now, to the right of the z-score 1.44, the area we are considering is the probability below;
P( z > 1.44)
To get this value, we need to use the standard normal distribution table
Checking this, the probability is
P( z > 1.44) = ) = 0.074934 which is 0.0749 for a four decimal digit

Answers
Answer:
$13.42
Step-by-step explanation:
Two potatoes cost $2.50
$3.75 ÷ 3 = $1.25 $1.25 x 2 = $2.50
1 lb of asparagus is $2.48
$4.95 ÷ 2 = $2.48
2 lbs of fish cost $8.44
$12.65 ÷ 3 = $4.22 $4.22 x 2 = $8.44
$2.5 + $2.48 + $8.44 = $13.42

Brice has $30 to take his brother and his friends to the movies. If each ticket costs $4.00, and he must buy tickets for himself and his brother, what is the
greatest number of friends he can invite?
Answers
Answer:
5 friends
Step-by-step explanation:
beacuse it costs $8.00 for himself and his brother, and he can only invite 5 friends because $30 - $8 is $22
so $22 divided by 4 is 5
Answer:
5
Step-by-step explanation:
You start with $30, and each ticket cost $4.
You have to buy AT LEAST 2 tickets for Brice (yourself in the story) and Brice's brother. That 30-8=22.
22/4=5 (without going over 22)
Chase drew a scale drawing of a community college. A building at the college, which is 260 meters long in real life, is 286 millimeters long in the drawing. what scale did chase use?
Answers
Given parameters:
Actual length = 260m
Drawing length = 286mm
Unknown:
Scale used = ?
Solution:
A scale compares drawing length to ground distance;
To find the scale,
Express the two quantities in the same unit;
actual length = 260 x 10⁻³m = 0.26mm
Now;
drawing length : actual length
286mm : 260 x 10⁻³mm
divide by 286;
1mm on drawing : 9 x 10⁻⁴mm on map
or;
1mm on drawing is 0.9m on ground

This graph represents −x−2y=−4 .
Which ordered pair is in the solution set of −x−2y≤−4 ?
A. (−4, 1)
B. (−1, 4)
C. (−4, −1)
D. (4, −1)
Answers
Answer:
B
Step-by-step explanation:
We have the equation [tex]-x-2y=-4[/tex] and we want to find which ordered pair is in the solution [tex]-x-2y\leq -4[/tex]
First, let's convert the inequality to slope-intercept form. So, we have:
[tex]-x-2y\leq-4[/tex]
Add x to both sides:
[tex]-2y\leq x-4[/tex]
Divide both sides by -2. Since we're dividing by a negative, we will flip the sign:
[tex]y\geq- \frac{1}{2}x+2[/tex]
Therefore, our original inequality will be the same as above.
Notice that our y is greater than our equation.
Therefore, the shaded area will lie above our line.
So, any point that falls within the region above our line (in the graph) and on the line is a solution to our inequality.
(-4, 1) is below our line, so it's not a solution.
(-1, 4) is above our line. So, (-1, 4) is our answer.
(-4, -1) is again below our line. So, it's not a solution.
Finally, (4, -1) is also below our line, so it's not a solution.
Therefore, our final solution is B: (-1, 4).
Let's check this. Substitute -1 for x and 4 for y. This yields:
[tex]-(-1)-2(4)\stackrel{?}{\leq}4[/tex]
Multiply:
[tex]1-8\stackrel{?}{\leq}{4}[/tex]
Subtract:
[tex]-7\stackrel{\checkmark}{\leq}4[/tex]
So, (-1, 4) is indeed our solution.
And we're done!

How do i do it?
(5x - 1) (5x - 1)
Ans: 25x^2 - 10x + 1
Answers
Now we have 25x^2 + -5x + 25x^2 -5x. Add like terms to get 50x^2 - 10x.
And the second method is using Pascals triangle but I’m not going to get much in detail as this is just a double extension bracket and all it will do is confuse you.
Answer:
Step-by-step explanation:
(5x - 1) (5x - 1)
= [tex](5x - 1)^{2}[/tex]
Using laws of exponents,
[tex](a - b)^{2} = a^{2} - 2ab + b^{2}[/tex]
here, a = 5x, b = 1
so it becomes,
[tex]5x^{2}[/tex] - 2 × 5x × 1 + [tex]1^{2}[/tex]
[tex]25x^{2}[/tex] - 10x + 1
