Answer:
parallel to the y axis (vertical line)
Step-by-step explanation:
On the x axis, from 0 count 5 units to the left (-5) and from this point, draw a line parallel to the y axis (vertical line)

Answer:
8(y + 27) ≤ -15
Step-by-step explanation:
In the given inequality statement, "Eight times the sum of a number and 27 is <u>at most</u> "-15""
The first part, "Eight times the sum of a number and 27" means that 8 is multiplied to the sum of y and 27. While the phrase "at most" means "<u>less than or equal to</u> (≤)" The phrase also implies that the value of y can be -15, or any value less than -15.
Therefore, the correct algebraic expression is: 8(y + 27) ≤ -15
Answer:
V = π /2 volume units
Step-by-step explanation:
Volume of y = √x bounded by y = x and y = 1
y = √x
limits of integration ( see Annex )
By simple inspection limits of integration are x = 0 to x = 1
or y = √x and y = x
solving these two equations
x = 0 y = 0 x = 1 y = ± 1
V = ∫ π*f(x)²*dx
V = π * ∫₀¹ x*dx = π * x²/2 |₀¹
V = π * (1/2) - 0
V = π /2 volume units
Answer: 0.000021 in scientific notation is
2.1 × 10-5
Step-by-step explanation:
All numbers in scientific notation or standard form are written in the form
m × 10n, where m is a number between 1 and 10 ( 1 ≤ |m| < 10 ) and the exponent n is a positive or negative integer.
To convert 0.000021 into scientific notation, follow these steps:
Move the decimal 5 times to right in the number so that the resulting number, m = 2.1, is greater than or equal to 1 but less than 10
Since we moved the decimal to the right the exponent n is negative
n = -5
Write in the scientific notation form m × 10n
= 2.1 × 10-5
Therefore,
2.1 × 10-5 is the scientific notation form of 0.000021 number and 2.1e-5 is the scientific e-notation form for 0.000021
