The size of a cell is typically found by capturing an image under a microscope then using software to measure its diameter. Two cells are measured using this method: Cell E: 8.39 x 10-² centimeters Cell F: 6.01 x 10-3 centimeters What's the difference between the diameters of the two cells? Express your answer using either standard notation or scientific notation.
Answer:
7.789×10^-2 = 0.07789 cm
Step-by-step explanation:
Your calculator can find the difference of the two given diameters and express it in any format you like.
The attached image of a calculator display shows the difference of the cell diameters is 0.07789 = 7.789×10^-2 cm.
__
The difference of two numbers with different exponents is found by first adjusting the exponents so they are the same. Here, we choose to adjust both numbers so they have the highest exponent value.
8.83×10^-2 - 6.01×10^-3
= 8.39×10^-2 - 0.601×10^-2 = (8.39 -0.601)×10^-2 = 7.789×10^-2
Alternatively, you can convert both numbers to standard form and do the subtraction that way.
8.83×10^-2 - 6.01×10^-3
= 0.0883 -0.00601 = 0.07789

Additional comment
The second attachment shows the relationship between place values and their multiplier in scientific notation.
__
The choice of exponent when computing the sum or difference of numbers in scientific notation is usefully informed by an estimate of the value of the sum or difference. A proper choice can avoid the need to adjust the exponent of the result of the operation. Here, we see the subtraction will change the larger value by less than 10%, so the exponent of the result in scientific notation will be that of the larger value (-2).

help? I can’t figure out this problem
Answer:
B
Step-by-step explanation:
Euler's formula tells you that ...
cos(θ) +sin(θ)·i ≡ e^(i·θ)
__
So, for θ = 90° (= π/2 radians), this is ...
cos(π/2) +sin(π/2)·i = 0 +i = i = e^(i·π/2) . . . . . matches choice B

Based on the family the graph below belongs to, which equation could represent the graph ?
Firstly this looks like translated log function graph
y=logxlog1=0
As per graph the graph is pulled some inwards y axis but little bit
y=log2xUsually log x leaves y axis at -1 but here it leaves at +2
So
y axis is moved upwards (+3)

A rectangle has dimensions 2x – 12 by 3x + 9 and area 60 cm². What are the actual
dimensions of the rectangle?
Answer:
2 x 30 cm
Step-by-step explanation:
L x W = 60
(2x-12)(3x+9) = 60
6x^2 -18x-168=0
use quadratic fromula to find x = 7 or -4 (throw out)
the sides then become ( using 7)

7. The graph shows the height, h, in feet, of water
sprayed from a fountain as a function of the
horizontal distance, d, in feet, the water has
traveled.
Water Fountain
h

69 12 15
Horizontal Distance (ft)
What is the domain of the function described in the
graph?
OA. All whole numbers less than or equal to 16
OB. All non-negative real numbers less than or
equal to 18
OC. All non-negative real numbers less than or
equal to 16
OD. All whole numbers less than or equal to 18
Height (ft)
20
16
12
18
The domain is talking about the "range" of the horizontal axis therefore you will be focusing on the x-intercepts.
The answer will be All non-negative real numbers less than or equal to 18
because the x-intercepts lies at 0 and 18. The answer makes sense because the furthest you can go is 18 ft and the closest you could go is 0 ft. The "all non-negative real numbers" puts a restriction on the least distance it could travel so that means that it stops at 0 ft because if you go any further, you will end up in the negatives and it clearly states "non-negative".
find three consecutive positive integers such that the product of the first and the third integer os 29 more than the second
Answer:
5, 6, 7
Step-by-step explanation:
let the 3 consecutive integers be n , n + 1 , n + 2 , then
n(n + 2) = n+ 1 + 29
n² + 2n = n + 30 ( subtract n + 30 from both sides )
n² + n - 30 = 0 ← in standard form
(n + 6)(n - 5) = 0 ← in factored form
equate each factor to zero and solve for n
n + 6 = 0 ⇒ n = - 6
n - 5 = 0 ⇒ n = 5
n > 0 , then n = 5
the 3 integers are 5, 5 + 1, 5 + 2 , that is
5, 6, 7

Hey there!
To answer this question you have to plug in your values and do PEMDAS.
PEMDAS simply means
• Parentheses
• Exponents
• Multiplication
• Division
• Addition
• Subtraction
WE CAN ANSWER THE EQUATION
1/4(c^3 + d^2)
= 1/4(-4^3 + 10^2)
= 1/4(-64 + 100)
= 1/4(-64) + 1/4(100)
= -16 + 25
= 9
OR
1/4(c^3 + d^2)
= 1/4(-4^3 + 10^2)
= 1/4(36)
= 9
Therefore, your answer is: 9
Good luck on your assignment & enjoy your day!

Serena took two numbers which may or may not be integers, rounded
each of them up to the nearest integer, multiplied the results, and
got 100. When she took the original numbers, rounded each of them
down to the nearest integer and multiplied the results, she got X.
Find the largest possible value of X.
( The Answer is 202, please give a step by step solution)
Thank You
Recall (or "define", if you're not familiar) the so-called ceiling and floor functions, or least/greatest integer functions, respectively; for any integer n,
• ceiling function:
[tex]\lceil x \rceil = n \text{ if } n-1 < x \le n[/tex]
• floor function:
[tex]\lfloor x \rfloor = n \text{ if } n \le x < n+1[/tex]
Let x and y be the two numbers Serena picks. She finds that
[tex]\lceil x \rceil \lceil y \rceil = 100[/tex]
[tex]\lfloor x \rfloor \lfloor y \rfloor = X[/tex]
Assume x and y are not integers. Let m and n be two integers such that m - 1 < x < m and n - 1 < y < n. Then
[tex]\lceil x \rceil \lceil y \rceil = mn = 100[/tex]
so m and n are divisors of 100. There's a finite number of distinct divisor pairs (m, n) to consider,
(± 1, ± 100), (± 2, ± 50), (± 4, ± 25), (± 5, ± 5)
whose sums can be one of
± 101, ± 99, ± 52, ± 48, ± 29, ± 21, ± 10, 0
Similarly,
[tex]\lfloor x \rfloor \lfloor y \rfloor = (m-1)(n-1) = 101 - (m + n) = X[/tex]
which is maximized if the sum m + n is negative; the largest of these is m + n = -101, so the maximum value of X is 101 + 101 = 202.
The reasoning for the case of either x or y, or both, being integers is nearly identical.
Julia's car used 1/100 of a gallon to travel 0.25 miles. How many miles can the car go on one gallon of gas? On the double number line below, fill in the given values, then use multiplication to find the missing value. Enter your answers as fractions, whole numbers, or decimals. miles 0 gallons Enter your final answer as a whole number or decimal.
Answer:
25 miles
Step-by-step explanation:
well
1/100 = 0.25
10/100 = 2.5 (Because 0.25 x 10)
100/100 = 25 (Because 0.25x100)
if m<1=2x+2 and m<2=9x, find m<1
Answer:
18/7
Step-by-step explanation:
Since m<2 includes 1, m<2 = m<1
9x = 2x + 2 ⇒ 7x = 2 ⇒ x = 2/7
m<1 = 2(2/7) + 2 = 4/7 + 14/7 = 18/7
