Answer:
y=2500(0.85)^d
Step-by-step explanation:
Seeing as there are no option choices, I shall digress.
Because of a decrease of 15% each day, it means exponential decay. Using the formula y=a(1-r)^x, we have y=2500(1-0.15)^d -> y=2500(0.85)^d
Your function would thus be y=2500(0.85)^d
Answer:
The function that can be used is x = (2500 × 0.15)(number of days, or d)
Step-by-step explanation:
First we can create an equation to find this easier. We can say that x, or the number of infected students, is equal to (2500 × 0.15), since percentages are easily changed into decimals, and multiply that by the number of days or d.

in your answer
Enter the answer.
9514 1404 393
Answer:
f(x)=0
Step-by-step explanation:
For the function to be both even and odd, you must have ...
f(-x) = f(x) = -f(-x)
Adding f(-x) we have ...
2f(-x) = 0
Then dividing by 2 and recognizing f(-x) = f(x), we have ...
f(-x) = f(x) = 0

Use the multiplier method to increase £258 by 43%
You must show your working out.
Answer:
£368.94
Step-by-step explanation:
The multiplier for 43% is 0.43
0.43 x 258 = 110.94 which is 43%
But if you are increasing 258 by 43% you must add on 258 as well
Or instead you can just do 258 x 1.43= 368.94

Select the correct answer. Victor and Dennis are weeding a garden. If Victor worked alone, it would take him 30 minutes. Working together, they would finish in 12 minutes. When x represents the number of minutes it would take Dennis working alone, this situation is represented by this equation: Working alone, how long would it take Dennis to weed the garden? A. 15 minutes B. 18 minutes C. 20 minutes D. The rational equation has no valid solutions.
Answer:
C. 20 minutes
Step-by-step explanation:
If Victor (V) worked alone, it would take him 30 minutes.
30 * V = 1
V = 1 / 30
When x represents the number of minutes it would take Dennis (D) working alone,
x * D = 1
D = 1 / x
Working together, they would finish in 12 minutes
12 (V + D) = 1
12( 1/30 + 1/x) =1
1/30 + 1/x = 1/12
Multiply all through by x
x/30 + 1 = x/12
x/30 - x/12 = - 1
( 2x - 5x ) / 60 = - 1
- 3x / 60 = - 1
- 3x = -60
x = -60 / -3 = 20 minutes
- El valor de las acciones de una empresa en bolsa disminuye $35 cada día. Si hoy
valen $23570 ¿cuánto costarán dentro de 3 días?. ¿Cuánto valían 12 días atrás?
Answer:
1. 23,465 2. 23,150
Step-by-step explanation:
1. 35 por 3 es 105 entonces en el tercer día sería 23570 - 105 = 23,465
2. Hacemos lo mismo 35 por 12 es 420 ahora hacemos 23570 - 420 = 23,150

- Mia and Lily are trying to find the nearest whole number to the square root of 120
Mia: It is 10
Lily: It is 11
Who is correct?
Give a reason for your answer.
For determining the nearest whole number for the square root of 120, the Lily is correct i.e. it is a square of 11.
Given that,
Mia has 10 number.And, Lily is 11 number.Now if we square both the numbers so it comes:
10^2 = 10011^2 = 121So, 121 is nearest to 120.
Therefore we can conclude that for determining the nearest whole number for the square root of 120, the Lily is correct i.e. it is a square of 11.

Find the midpoint of the line segment with end coordinates of:(−1,−6) and (4,5)
Give coordinates as decimals where appropriate.
The midpoint of the line segment with endpoints (-1, -6) and (4, 5) is (3/2, -1/2).
Finding the midpoint of the line segmentThe midpoint of a line segment with endpoints (x1, y1) and (x2, y2) is given by the coordinates:
((x1 + x2)/2, (y1 + y2)/2)
In this case, the endpoints are (-1, -6) and (4, 5), so we can plug in the values:
((x1 + x2)/2, (y1 + y2)/2) = ((-1 + 4)/2, (-6 + 5)/2)
Simplifying this expression, we get:
((x1 + x2)/2, (y1 + y2)/2) = (3/2, -1/2)
Therefore, the midpoint of the line segment with endpoints (-1, -6) and (4, 5) is (3/2, -1/2).
