Answer:
32 million
Step-by-step explanation:
Given that:
Time it takes population to double = 21 minutes
Number of bacteria at 10a.m = 8,014,000
Best estimate of bacteria at 10:42
Difference :
10:42 - 10:00 = 42 minutes
42/ 21 = 2 times
Hence it doubles 2 times within the time range :
At 10:21 minutes :
8,014,000 * 2 = 16,028,000
At 10:42 minutes :
16,028,000 * 2 = 32,056,000
Best estimate is 32 million

The answer is 3.
Step-by-step explanation:
4d + 5 - 9d + 2 = 13
Answer: d = -1.2
Step-by-step explanation: First you combine like terms. You add 5 +2 which gives you 7, and then you subtract 9 from 5 which gives you -5d. Then you subtract 7 from 13 which gives you 6. Divide both sides by -5 and you get -1.2. Always make sure to check your answer by plugging your answer into the place of the d variable
3x - 7y = 13; x = -3, 0, 3
Solve the equation for y.
and solve for x.
Answer:
when x = -3; y = -22/7
when x = 0; y = -13/7
when x = 3; y = -4/7
y = 3/7x - 13/7
x = 7/3y + 13/3
Step-by-step explanation:
x = -3; 3(-3) - 7y = 13; -9 - 7y = 13; -7y = 22; y = -22/7
x = 0; 3(0) -7y = 13; -7y = 13; y = -13/7
x = 3; 3(3) -7y = 13; 9 - 7y = 13; -7y = 4; y = -4/7
SOLVE FOR Y: 3x - 7y = 13; -7y = -3x + 13; y = 3/7x - 13/7
SOLVE FOR X: 3x - 7y = 13; 3x = 7y + 13; x = 7/3y + 13/3

I hope this helps. u said 45 minutes, so i tried to some up with an answer. best of luck on ur work
Step-by-step explanation:
car a is 57 km in an hour, as 57t is equal to d. This, when d is 57 km will be 1 hr. So we are assuming that "t" is 1. Then d is 57. NOw lets check out car b. 140/2 is for 2 hrs, 210/3 for 3 hrs, and 280/4 for 4 hrs. This gives rate of 70 km in 1 hr.

Yes, Converse of Alternate Interior Angles Postulate
Yes, Converse of Alternate Exterior Angles Postulate
Yes, Converse of Consecutive Interior Angles Postulate
Answer:
Option (1)
Step-by-step explanation:
From the picture attached,
Lines 'm' and 'n' are the parallel lines and 'r' is a transversal line intersecting these lines at two distinct points.
Therefore, both the angles will be congruent by the property of corresponding angles postulate.
By the converse of corresponding angles postulate,
If these angles are congruent then both the lines (m║n) will be parallel.
Option (1) will be the answer.

Which of these functions are linear ?
Answer:
E
Step-by-step explanation:
A function that is linear is a straight line. A linear function can be found using [ y = mx + b ]
F shows an example of a quadratic function. A quadratic function can be found using [ f(x) = ax² + bx + c ]
Best of Luck!
[tex] \LARGE{ \underline{ \blue{ \bf{Required \: answer:}}}}[/tex]
The answer is E because the graph of linear equation is a straight line whereas the graph of a quadratic equation is a parabola opening upwards or downwards depends upon the coefficient of a in standard form : ax² + bx + c.
Linear equation have atmost 1 zero. This we can determine through the graph.Quadratic equation have atmost 2 zeroes and the no. of times it intersect with x-axis determines the no. of zeroes of the quad. equation.#CarryOnLearning

Imaginary number test
i ⁴³⁵ = i ⁴³²⁺³ = i ⁴³² • i ³
i ⁴³⁵ = i ⁴³² • i ³
i ⁴³⁵ = (i ⁴)¹⁰⁸ • i ³
i ⁴³⁵ = 1¹⁰⁸ • (-i)
i ⁴³⁵ = -i
The value of the imaginary number i⁴³⁵ is : i ⁴³⁵ = -i.
Here, we have,
To evaluate the expression i⁴³⁵, we need to understand the properties of the imaginary unit, denoted by i.
The imaginary unit i is defined as the square root of -1, meaning i² = -1.
When raising i to an exponent, we can use the pattern of powers of i to simplify the expression.
The pattern of powers of i repeats every four exponents:
i¹ = i
i² = -1
i³ = -i
i⁴ = 1
Since i⁴ = 1, we can divide the exponent 435 by 4 to find the remainder:
435 divided by 4 gives a remainder of 3.
Therefore, i⁴³⁵ is equivalent to i³.
Using the pattern of powers of i, we know that i³= -i.
So, i⁴³⁵ = -i.
i.e. we get,
i ⁴³⁵ = i ⁴³²⁺³ = i ⁴³² • i ³
i ⁴³⁵ = i ⁴³² • i ³
i ⁴³⁵ = (i ⁴)¹⁰⁸ • i ³
i ⁴³⁵ = 1¹⁰⁸ • (-i)
i ⁴³⁵ = -i

An aircraft flies at an average speed of 500 miles per hour. The expression 500t gives the distance traveled by the aircraft in t hours. Find the distance traveled by the aircraft in 8 hours The distance traveled by the aircraft in 8 hours is
Distance = 500 t
This equation means if we multiple 500 by the given time, we can determine the distance traveled.
Given in the question.
t = 8 hours
So we can substitute 8 into the equation.
Distance = 500 x 8
Distance = 4000 miles
Therefore, it traveled 4000 miles in 8 hours.
An expression is defined as a set of numbers, variables, and mathematical operations. The distance traveled by aircraft in 8 hours is 4,000 miles.
What is an Expression?In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.
Given that the expression 500t gives the distance traveled by the aircraft in t hours. Therefore, the function can be written for distance as,
D(t) = 500t
where D is the distance in miles and t is the time in hours.
Now, To know the distance traveled by aircraft in 8 hours simply substitute the value of t as 8 in the given equation. Therefore, The distance traveled by the aircraft in 8 hours is,
D(t) = 500t
D(8) = 500(8)
= 4,000 miles
Hence, the distance traveled by aircraft in 8 hours is 4,000 miles.
