A The number of bacteria increases by t after 4 days
B. The number of bacteria increases by a factor of teach day for 5 days.
C. The number of bacteria increases by a factor of 4 each day
D. The number of bacteria increases by 4 each day
i need help please!!
From the given equation, [tex]4^{t}[/tex] represent the number of bacteria increases by a factor of 4 each day.
What is an equation?An equation can be defined as a mathematical statement consisting of an equal symbol between two algebraic expressions that have the same value.
A microbiologist during a study on a culture of 250 bacteria noticed that he can model the number of bacteria after t number of days by the equation
[tex]B = 250 \times[/tex] [tex]4^{t}[/tex]
t stands for training days(Add one to the power of 4 every day)
Every day is four time more than the day before.
So, the number of bacteria increases by a factor of 4 each day.
So, this answer is Option C.

The yearbook staff receive 75 submissions for yearbook articles. Paul will accept 2/5 of all submissions. Currently, Paul plans for the yearbook to have 156 pages.
Answer 813.8
Step-by-step explanation:
Well 813.8 is the answer. Why? Lets talk it out if there are 75 submissions and it says Paul will accept 2/5 of the submissions so we have to do is 75- 2/5 will be 74.6 and multiply by 13 because 13 pages is in a article so we got 969.8 and then minus 156 because it asking us how many "more" pages they need so 813.8 is the answer if you subtract 969.8 and 156.
If the can is full of paint with a radius of 5 and height of 14 inches, what is the total amount of paint in the can?
Answer:
1,099 cubic inch or 18.01 liter
Step-by-step explanation:
According to the scenario, computation of the given data are as follows,
Radius (r) = 5 inches
Height (h) = 14 inches
So, Volume of can = π[tex]r^{2}[/tex]h
By putting the value in the formula, we get
= π [tex]5^{2}[/tex] × 14
= π 25 × 14
= 350π
= 350 × 3.14
= 1,099 cubic inch
As 1 liter = 61.02 cubic inch
So, 1,099 ÷ 61.02 = 18.01 liter
Which equation shows a line with the
slope of 5 that passes through point (2, -3)?
Answer:
y = 5x - 13
Step-by-step explanation:
point slope form: y - y1 = m (x - x1)
plug in: y1 = -3, x1 = 2, m = 5
y - (-3) = 5 (x - 2)
y + 3 = 5x - 10 <- simplify and expand
y = 5x - 13 <answer for slope intercept
equation: y = 5x - 13

Find the zeros of y = x2 - 6x – 4 by completing the square.
O A. x = 3 + 5
B. X = +3
C. X = 3 + 13
D. x.-3113
Answer:
√13 + 3 = x
-√13 + 3 = x
Step-by-step explanation:
y = x² - 6x - 4
0 = x² - 6x - 4
0 + 13 = x² - 6x - 4 + 13
13 = x² - 6x + 9
13 = (x-3)²
±√13 = x-3
±√13 + 3 = x
√13 + 3 = x
-√13 + 3 = x
Which of the following equations results in infinitely many solutions?
Select the correct answer. Let f(x) and g(x) be polynomials as shown below.
Answer:
f(x) and g(x) are closed under multiplication because when multiplied, the result remains a polynomial.
Step-by-step explanation:
First, to be closed means that once an operation has commenced, the result is a polynomial, just like the two original ones.
When polynomials are multiplied, exponents simply add together, and constants are multiplied. A polynomial is a finite sum of terms in which all variables have whole numbered exponents.
In this scenario, when we multiply polynomials, exponents are solely added together, and one whole number plus another is still a whole number. Similarly, constants multiplied by constants stay as constants, and constants multiplied by variables keeps it in polynomial form. (e.g. 3 * x² makes it 3x², and 3x² is fine in a polynomial).
Therefore, given these facts, f(x) and g(x) are closed under multiplication because when multiplied, the result remains a polynomial.
k is a prime number and f(x) = k has no solutions.
Find the possible values of k.
Answer:
Suppose x∈R is such that x+20x=p is a prime. Then x2−px+20=0 , and this equation has a solution x∈R if and only if p2–80≥0 . So the primes which admit no real solution are those that satisfy p<80−−√ , or 2 , 3 , 5 , and 7 . ■
Step-by-step explanation:
E? <3
The primes which accept no real solution exist as those that satisfy
p<[tex]\sqrt{80}[/tex], or 2, 3, 5, and 7.
What is a prime number?A prime number exists as a real number greater than 1 whose only factors that exist are 1 and itself. A factor exists as an entire number that can be divided evenly into another number. The first prime numbers exist 2, 3, 5, 7, 11, 13, 17, 19, 23, and 29. Numbers that contain better than two factors exist named composite numbers.
If the function f(x) = (20/x) + x = k. Suppose x∈R exists such that x+20x=p exists a prime. Then [tex]$x^2-px+20=0[/tex], and this equation contains a solution x∈R if and only if [tex]$p^2-80[/tex] ≥ 0. So the primes which accept no real solution exist as those that satisfy p < [tex]\sqrt{80}[/tex], or 2, 3, 5, and 7.

9x - 2y = 19, 7x = 21
System of Equation
9x - 2y = 19, 7x = 21
7x = 21
=> x = 21/7
= x = 3 —————(1)
9x - 2y = 19
=> 9(3) - 2y = 19 [From (1)]
=> 27 - 2y = 19
=> -2y = 19 - 27
=> -2y = -8
=> y = -8/-2
=> y = 8/2
=> y = 4
So, x = 3 and y = 4.

Answer:
The correct answer is – 1/2
Answer:
The answer is -1/2
Step-by-step explanation:
If we compare this with y = mx + c, we can do a comparison. m is the slope and c is the added constant.
Since y = -1/2 x + 1/4,
m = -1/2
Since m is the slope, the slope is -1/2.

At Dunkin Donuts the corn muffins they make represent 40% of the total muffins they bake everyday. On Monday they make 20 corn muffins. How many total muffins did they bake?
Answer:
50 muffins
Step-by-step explanation:
20 : 40%
y : 100%
[tex]\frac{20}{y} :\frac{40}{100}[/tex]
y · 40 = 20 · 100
40y = 2000
40y ÷ 40 = 2000 ÷ 40
y = 50
Answer:
50
Step-by-step explanation:
first you must find out how many muffins are in 1%, that will be .5 muffins which also meens that every 2% there will be 1 muffin. so we do 100 dived by 2 and you will get 50 which is the amount of muffins that will be made
Brian sent 9 more messages than salma and Chang sent 2 times more than Brian and they have 55 messages total how many messages do they have each
Answer:
See explanation
Step-by-step explanation:
Let
x = number of messages Salma sent
x + 9 = number of messages Brian sent
2(x + 9) = number of messages Chang sent
Total messages sent = 55
x + (x + 9) + 2(x + 9) = 55
x + x + 9 + 2x + 18 = 55
4x + 27 = 55
4x = 55 - 27
4x = 28
x = 28/4
x = 7
Number of messages Salma sent = x = 7 messages
Number of messages Brian sent = x + 9
= 7 + 9
= 16 messages
Number of messages Chang sent = 2(x + 9)
= 2(7 + 9)
= 2(16)
= 32 messages
What is an equation of the line that passes through the points (6, -3)and (−6,−5)?
Answer:
y = 1/6x -4
Step-by-step explanation:
First find the slope
m= ( y2-y1)/(x2-x1)
m=(-5 - -3)/( -6 -6)
= (-5+3)/ (-6-6)
= -2/-12
= 1/6
The slope intercept form is
y= mx+b where m is the slope and b is the y intercept
y = 1/6 x +b
Substitute a point into the equation
-5 = 1/6(-6) +b
-5 = -1+b
Add 1 to each side
-4 = b
y = 1/6x -4
Answer:
y=1/6x-4
