Answer:
Step-by-step explanation:
Using the equation of motion
S = ut+1/2gt²
S is the height of fall
g is the acceleration due to gravity = 9.81m/s²
u is the initial velocity = 0m/s
t is the time = 6s
Substitute in the formula;
S = 0+1/2(9.81)×6²
S = 4.905×36
S = 176.58m
The shaft is 176.58m deep
Given the expression for distance
S = 16t²
Velocity V = dS/dt
V = 32t
Given v = 1100
1100 = 32t
t = 1100/32
t = 34.375secs
Substitute t = 34.375 into S = 16t²
S = 16(34.375)²
S = 18,906.25ft
A line passes through the points (−8,−7) and (−4,−4). What is the equation of the line in Slope-Intercept Form? (A y=43x−1) (B y=34x−1) (C y=43x+1) (D y=34x+1)
Answer:
y=43x−1
Step-by-step explanation:
The equation of the line in Slope-Intercept Form is B: y = (3/4)x − 1.
What is the meaning of Slope-Intercept Form?The slope intercept form of such a straight line is among the most common ways to represent a line's equation. When given the slope of a straight line and the y-intercept, the slope intercept equation can be utilized to find the equation of a line.For the given question.
The line passes through the points-
(x1, y1) = (−8,−7)
(x2, y2) = (−4,−4).
Find the slope using formula;
slope = m = (y2 - y1)/(x2 - x1)
m = (-4 + 7)/(-4 + 8)
m = 3/4
The equation of the line in slope intercept form is found by;
y - y1 = m(x - x1)
y + 7 = (3/4)(x + 8)
y = (3/4)x - 1
Thus, the equation of the line in Slope-Intercept Form is B: y = (3/4)x − 1.

Answer:
C) 6^6
Step-by-step explanation:
When we divide same base numbers with different exponents, the answer will be the base raised to the power of the difference of those exponents:
The rule is: x^a/x^b=x^(a-b)
In this case: 6^9/6^3=6^(9-3)=6^6=46656
Therefore, C is the correct answer
x²=169 extracting square root
Answer:
x = ± 13
Step-by-step explanation:
Given
x² = 169 ( take the square root of both sides )
x = ± [tex]\sqrt{169}[/tex] = ± 13
Since 13 × 13 = 169 and - 13× - 13 = 169
select the correct answer. solve: -36 4/9-(-10 2/9)-(18 2/9

Joe lives in a city that is 15 feet below sea level. How could he
represent his elevation as an integer?
Answer:
He could say that he is -15 feet as seen from the sea level
The given statement can be represented in an integer as -15.
Given that, Joe lives in a city that is 15 feet below sea level.
We need to find how could he represent his elevation as an integer
How will you represent a sea level as an integer?Whole numbers less than zero are called negative integers (-). These numbers are to the left of zero on the number line. Zero is neutral. It is neither positive nor negative.
Now, 15 feet below sea level can be represented as -15.
Therefore, the given statement can be represented in an integer as -15.

Answer:
(x + y)² = 121
Step-by-step explanation:
Using the identity
(x + y)² - (x - y)² = 4xy , then
(x + y)² - 5² = 4(24) , that is
(x + y)² - 25 = 96 ( add 25 to both sides )
(x + y)² = 121
You need to write an essay that has at least 700 words. You have written 300 words so far. Write an inequality that represents the number of words w that you have left to write.
Answer:
300 + w ≤ 700
Step-by-step explanation:
It would not be 300 + w = 700 because you have to write at least 700 words, so 300 + w must be equal to or greater than 700, and the equal to or greater than sign is ≤
