−3(2.5−k)+0.5(7+8k).
Answer:
7k-4
Step-by-step explanation:
(-3)(2.5)+(-3)(-k)+(0.5)(7)+(0.5)(8k)
-7.5+3k+3.5+4k
Then you combine like terms
-7.5k+3k+3.5+4k
(3k+4k)+(-7.5+3.5)
7k+-4

A bacteria culture grows with constant relative growth rate. The bacteria count was 1296 after 2 hours and 531441 after 6 hours. Answer the following questions. 1. What is the relative growth rate
Answer:
1)k=1.50408
2)=64
3)P(t)=64e^(1.50408t)
4)=118098
5)t=6.42 hrs
Step-by-step explanation:
CHECK THE COMPLETE QUESTION BELOW
A bacteria culture grows with constant relative growth rate. The bacteria count was 1296 after 2 hours and 531441 after 6 hours. Answer the following questions.
1. What is the relative growth rate?
2. What was the initial size of the culture?
3. Find an expression for the number of bacteria after t hours.
4. Find the number of cells after 5 hours.
5. When will the population reach 1000000?
To find relative growth rate, expression below can be used
P(t)= Po*e^(kt)
Where k= growth rate
Po= initial amount
t= time in hours
We were given The bacteria count as 1296 after 2 hours and 531441 after 6 hours. This can be expressed below as
P(2)= P(o)e^(2k)= 1296.........eqn(1)
P(6)= P(o)e^(6k)= 531441........eqn(2)
If we find the ratio of the two eqn we have
531441/1296 =[P(o)e^(6k)]/[P(o)e^(2k)]
410.0625= e^(4k)
If we take Ln of both side
ln 410.0625=ln(e^4k)
k=1.50408
1)= k=1.50408
2)
From P(2)= Po*e^(2k)= 1296
1296=Po × e^(2×1.50408)
1296= Po × e^(3.00816)
Po=1296/e^(3.00816)
=64
3) the expression is P(t)=64e^(1.50408t)
4). P(5)=64e^(1.50408×5)
=118098
5) P(t)= 1,000,000
1000000=64e^(1.50408t)
1000000/64 = 64e^(1.50408t)
Ln(15625)=ln[e^(1.50408t)]
9.657=e^(1.50408t)
t=6.42 hrs

f f(x) is a linear function, which statement must be true? f(x) has no constant term. f(x) has no x2-term. f(x) has no terms with a coefficient other than 1. f(x) has no x-term. Mark this and return
Answer:
f(x) has not x^2 term.
Step-by-step explanation:
Linear function is in the form of y=mx+b
In the linear function y=mx+b there is a constant term b
There is also an x term.
m is the slope of f(x). The value of 'm' can be any number.
If we have x^2 term in f(x) then it is quadratic function.
Linear function must always have x with exponent 1
True option is f(x) has not x^2 term.
Cindy runs a company that designs and prints gift cards for a department store. Quality controls is very important,
and Cindy must determine that the cards are being printed properly. For every 6,000 batches of 100 cards that are
printed, she examines every 100th batch to make sure the logo is aligned and the magnetic strip works. Identify the
population and the sample.
population: 6,000 batches of 1000 cards c. population: 6,000 batches of 1000 cards
sample: every 10,000 cards
sample: every 100th batch
b. population: 6,000 batches of 100 cards d. population: 6,000 batches of 100 cards
sample: every 10,000 cards.
sample: every 100th look
The answer is C which is population 6,000 batches of 1,000 sample: every 100th batch

Answer:
(f + g)(3) = 9
Step-by-step explanation:
f(x) = x² + 1
g(x) = x - 4
Thus:
(f + g)(x) = (x² + 1) + (x - 4)
(f + g)(x) = x² + 1 + x - 4
(f + g)(x) = x² + x - 3
Therefore, to find (f + g)(3), plug in the value of 3 into the equation:
(f + g)(3) = (3)² + 3 - 3
(f + g)(3) = 9 + 3 - 3
(f + g)(3) = 9

A coin is tossed and a six-sided die numbered 1 through 6 is rolled. Find the probability of tossing a head and then rolling a number greater than 1.
Answer:
[tex]Probability = 0.4167[/tex]
Step-by-step explanation:
Given
A toss of coin and a roll of 6-sides die
Required
P(Head and Number greater than 1)
First, we list the sample space of the coin:
[tex]Sample\ Space = \{Head, Tail\}[/tex]
From the sample space above:
[tex]P(Head) = \frac{1}{2}[/tex]
Next, we list the sample space of the die:
[tex]Sample\ Space = \{1,2,3,4,5,6\}[/tex]
There are 5 outcomes greater than 1; i.e. 2,3,4,5 and 6.
So:
[tex]P(Outcome> 1) = \frac{5}{6}[/tex]
Lastly, the required probability is calculated as:
[tex]Probability = P(Head) \ and \ P(Outcome>1)[/tex]
Change and to *
[tex]Probability = P(Head) \ * \ P(Outcome>1)[/tex]
Substitute values for P(Head) and P(Outcome > 1)
[tex]Probability = \frac{1}{2} * \frac{5}{6}[/tex]
[tex]Probability = \frac{5}{12}[/tex]
[tex]Probability = 0.4167[/tex]

Carlos wants to rent a car. For the particular car he wants, Gentle Rental charges $185 per week plus 25 cents per mile driven. Rental Giant charges a flat fee of $275 per week. What is the number of miles driven so that renting from Gentle Rental cost Carlos less than renting from Rental Giant?
A. Less than or equal to 360 miles
B. Less than 360 miles
C. Less than or equal to 115 miles
D. Less than 1,840
Answer:
B. Less than 360 miles
Step-by-step explanation:
Let the number of miles driven be [tex]x[/tex]
The cost of renting from Gentle Rental per week is
[tex]185+0.25x[/tex]
The cost of renting from Rental Giant per week is [tex]275[/tex].
Now we have to find after how many miles the cost of renting from Gentle Rental cost Carlos less than renting from Rental Giant
[tex]185+0.25x<275\\\Rightarrow 0.25x<275-180\\\Rightarrow x<\dfrac{90}{0.25}\\\Rightarrow x<360[/tex]
So, the answer is less than 360 miles.
The sum of the measures of two acute angles is always greater than 90 degrees
Answer:
One acute angle will always measure between 0° and 90° . Two acute angles can sum to be either greater than, less than, or equal to a right angle. Two acute angles can be complementary angles (adding to 90° ). Two acute angles alone cannot sum to make a straight angle (180° )

Suppose you flip a fair coin
1000 times. What do you think
is the probability of getting
exactly 500 heads?
Answer:
50
Step-by-step explanation:
first estimate probably 50% depends also in luck
Answer:
about 0.02
Step-by-step explanation:
If you toss a coin 1,000 times the average (mean) number of heads equals 500, yet the probability that you will get exactly 500 heads in 1,000 tosses is about 0.02.
