Element X is a radioactive isotope such that every 5 years, its mass decreases by half.
Given that the initial mass of a sample of Element X is 590 grams, how much of the
element would remain after 23 years, to the nearest whole number?
Answer: 24 grams of element would remain.
Step-by-step explanation:
Exponential function for decay:
[tex]f(x)=Ab^{\frac{x}{n}}[/tex] ....(i) , where A = initial value , b = decay factor, x = time , n= time per period
As per given,
A = 569 grams , [tex]b=\dfrac12[/tex]
n= 5 years, t = 23 years
Put all values in (i) , we get
[tex]f(23)=590(\dfrac12)^{\frac{23}{5}}\\\\\\=590\times 0.0412346222117\\\\=24.3284271049\approx 24[/tex]
Hence, after 23 years , 24 grams of element would remain.

an object dropped from a height of 210ft will fall according to the equation h(t) =210-16t^2. how long will it take the object to reach the ground
Answer:
[tex]\sqrt{210/16}[/tex]
Step-by-step explanation:
By saying reach the ground, it means the altitude w[tex]\sqrt{}[/tex]ill be zero, so the equation will be: 210 - 16t^2 = 0
210 = 16t^2, t = [tex]\sqrt{210/16}[/tex]

If the scale factor of a figure is 6, what is the new length of the enlarged figure matched to the length of the
orginal?
Answer:
1=6
7=42
2.5=15
5=30
Step-by-step explanation:
Multiply each original value by the scale factor
1×6=6
7×6=42
2.5×6=15 (2×6 + 6×0.5)
5×6=30
Answer:
Original: 5 cm = Enlarged: 30 cm
Original: 7 cm = Enlarged: 42 cm
Original: 2.5 cm = Enlarged: 15 cm
Original: 1 cm = Enlarged: 6 cm

A senior employee who works 16 hours earns $39.50 more than a junior employee who works 18 hours. The senior employee earns $14 per hour. What is the hourly pay for the junior employee in dollars and cents?
(IN A TEST)
Answer:hourly pay for the junior employee in dollars and cents=$10.25
Step-by-step explanation:
Step 1
Total amount senior employee is being paid = amount per hour x hours worked
= $14 × 16 = $224.00
Total amount of junior employee since he/ she collects $39.50 less than senior employee= $224.00 - $39.50
= $184.50
Step 2
hourly pay of junior colleague= Total pay of junior colleague/ Hours worked
=$184.50 / 18 hours
= $10.25 per hour
A standard deck of 52 cards contains 4 suits: hearts, clubs, diamonds, and spades. Each suit contains cards numbered 2 through 10, a jack, a queen, a king, and an ace. Jacob Bearint decides to pick one card at random from a standard deck of 52 cards. What is the probability that the card Jacob chooses is either a four or a six? P ( 4 ∪ 6 ) =
Answer:
2 / 13
Step-by-step explanation:
Number of cards in a standard deck = 52
Number of 4's = 4 ( 1 for each suit)
Number of 6's = 4 (1 for each suit)
Probability, P = required outcome / Total possible outcomes
P(a 4) = 4 / 52 = 1/ 13
P(a 6) = 4 /52 = 1/13
Probability of either a 4 or a 6
P(a 4) + P(a 6)
1/13 + 1/13
= 2 / 13
Solve the compound inequality. 3x+2>2x−4>x−12

Step-by-step explanation:
Marlena has a bag of coins the bag contains 8 quarters 10 times 4 nickels + 2 pennies she would randomly select a coin from the bag what is the probability that Marlena will select and nickel
A) 1/12
B) 1/3
C) 1/6
D) 1/5
Plz help!!
Answer:
C) 1/6
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
In this question:
We have 8 + 10 + 4 + 2 = 24 coins
Of those, 4 are nickels. So
[tex]p = \frac{4}{24} = \frac{1}{6}[/tex]
The correct option is given by option C.
simplify 6e - 9 +10e
Answer:
16e-9
Step-by-step explanation:
===============================================================
In order to simplify this expression, we need to combine like terms:-
[tex]\longrightarrow\sf{6e+10e-9}[/tex]
Add the e's:-
[tex]\longrightarrow\sf{16e-9}[/tex]
Are there any more like terms? No, because 16e and -9 aren't like terms.

Based on the model, approximately how many customers will be on the restaurant when there are 10 cars parked in the restaurant’s parking lot?
A - 7
B - 23
C - 12
D - 28
Answer:
23
Step-by-step explanation:
From the graph, derive the best fit equation :
Using the points ;
(0,2.5) (100 ,35)
x1 = 0 ; y1 = 2.5 ; x2 = 100 ; y2 = 35
Slope formula, m = (y2-y1)/(x2-x1)
m = (35-2.5)/(100-0)
m= (32.5)/100
m = 0.325
The y intercept, value on the graph where best fit line crosses the y axis = 2.5
The equation :
y = mx + c
c = intercept ; m = slope
y = 0.325x + 2.5
y = Number of cars
x = number of customers
The number of customers if there are 10 cars parked :
10 = 0.325x + 2.5
10 - 2.5 = 0.325x
7.5 = 0.325x
x = 7.5 / 0.325
x = 23.076
x = 23
Given that log 2 = 0.3010 and log 3 = 0.4771, evaluate log√120 and leave your answer correct to four significant figure
Answer:
1.040
Step-by-step explanation:
log √(120)
= (1/2) log 120
120 = 2³ • 3 • 5
= 0.5(3 log 2 + log 3 + log 5)
Express log 5 in terms of log 2.
log 5 = log (10/2) = log 10 - log 2 = 1 - log 2
= 0.5(3 log 2 + log 3 + 1 - log 2)
= 0.5(2 log 2 + log 3 + 1)
= 0.5(2*0.3010 + 0.4771 + 1)
= 1.03955 or 1.040

Algebraically, find all remaining zeros of f(x) = 8x^3 - 6x^2-36x +27 in simplest form.
SHOW STEPS PLS
Answer:
[tex]x=-\frac{3\sqrt{2}}{2},\frac{3}{4},\frac{3\sqrt{2} }{2}[/tex]
Step-by-step explanation:
Given expression is,
f(x) = 8x³ - 6x² - 36x + 27
For zeros of the function,
f(x) = 0
8x³ - 6x² - 36x + 27 = 0
2x²(4x - 3) - 9(4x - 3) = 0
(2x² - 9)(4x - 3) = 0
(2x² - 9) = 0
x² = [tex]\frac{9}{2}[/tex]
x = [tex]\pm\frac{3}{\sqrt{2}}[/tex]
x = [tex]\pm \frac{3\sqrt{2}}{2}[/tex]
Or (4x - 3) = 0
x = [tex]\frac{3}{4}[/tex]
Therefore, all zeros of the given functions are [tex]x=-\frac{3\sqrt{2}}{2},\frac{3}{4},\frac{3\sqrt{2} }{2}[/tex].
Points A and B have the same x-coordinates but opposite y-coordinates. How many units away are each of the points from the y-axis?
3
4
6
7
Answer:
Each point is 4 units away from the y-axis.
Step-by-step explanation:
Coordinates of point (x, y) defines the distance of the point from y-axis and x-axis.
x-coordinate → distance from the y-axis
y-coordinate → distance from x-axis
Coordinates of A → (-4, 3)
Coordinates of B → (-4, -3)
So both the points have same x-coordinates but opposite y-coordinates.
Therefore, each point is 4 units away from the y-axis.
