Answer:
6.64 seconds
Step-by-step explanation:
Given that:
Distance between roof of the terminal and ground = 709 feet
A bucket was dropped from the roof.
To find:
The time taken by the bucket to hit the ground?
Solution:
Distance traveled, [tex]s[/tex] = 709 feet
Initial velocity of the bucket, [tex]u[/tex] = 0 feet/sec (because initially it was at rest)
Acceleration of the bucket will be equal to acceleration due to gravity i.e.
[tex]g[/tex] or 32.1741 [tex]ft/sec^{2}[/tex]
Let the time taken is [tex]t[/tex] seconds.
Formula for distance is given as:
[tex]s = ut+\dfrac{1}{2}at^2[/tex]
Putting all the values:
[tex]709 = 0 (t) + \dfrac{1}{2}(32.1741) t^2\\\Rightarrow 1418 = 32.1741 t^2\\\Rightarrow t^2 = 44.07\\\Rightarrow t \approx \bold{6.64\ sec}[/tex]

How to do this I’m struggling very badly
17x - y < 13
I’m slope-intercept form
Answer:
y > 17x - 13
Step-by-step explanation:
We want to write the inequality in slope-intercept form
The general slope intercept form is;
y = mx + b
where m is the slope and b is the y-intercept
So what we have to do to the inequality is to make y the subject
Thus, we have that;
17x -13 < y
Flipping this, we have
y > 17x-13
Write the rule for the linear function. Remember a function rule is written using f(f)
Answer:
y= -1/2x +0 because it's going down by 1/2 if you do rise over run, and the y intercept is 0
5(2x - 4) = 4x – 2
How would I solve this?
x=3

Aimee and Ben are purchasing a condominium and are financing $160,000. The mortgage is a 20 year 3/1 ARM with a cap structure of 1.5/10. What will their payments be for the first 3 years?
Answer:
$1169.45
Step-by-step explanation:
Using the formula:
[tex]P = L \Big( \dfrac{c(1+c)^n}{(1+c^n) -1} \Big)[/tex]
where;
Loan amount L = 160000
number of months (n) = 20 × 12 = 240
Lets assume that the interest rate per month c = 6.25% since it is not given.
i.e. (6.25/( 100*12) ) = 5.208 × 10⁻³
∴
[tex]P = 160000 * \dfrac{5.208 *10^{-3} (1+5.208 *10^{-3})^{240}}{(1+5.208 *10^{-3})^{240}-1}[/tex]
P = $1169.45
Please Help Me!!!!!!
Answer:
its C
Step-by-step explanation:
if y is 20 then you have to use the opposite of multiplication for 2/5 which would be division so 20 divided by 2/5 = 50
check answer by multiplying 2/5 and 50 to get 20

7th grade math help me please :))
Answer:
a) 23x
b) 8n
c) -6y
d) -17w
Explanation:
When combining like terms, if there is an addition operator, add both coefficients and carry the variable over. If there is a subtraction operator, subtract both coefficients and carry the variable over. Remember, you can only combine like terms if the variable, and exponent are the same. The addition and subtraction symbols are examples of an operator used in arithmetic. For example, 9x + 14x could be like adding 9 objects and 14 objects together, you have 23 objects total because 9 + 14 = 23. When you add negative numbers, it is like subtracting. When you subtract negative numbers, it is like adding. Negative just means opposite.
a) 9x + 14x = (9+14)x = (23)x = 23x
b) -2n - 10n = (-2+10)n = (8)n = 8n
c) 8y - 14y = (8-14)y = (-6)y = -6y
d) -6w - 11w = (-6-11)w = (-17)w = -17w
Answer:
a: 23x
b: 8n
c: -6y
d: -17w
Step-by-step explanation:
you just add/subtract the numbers then add the variable at the end

find the value of x.
Answer:
X= 20 degrees
Step-by-step explanation:
Because all the sides are the same length, we know this triangle is an equilateral triangle. In an equilateral triangle, all the angle measures are the same as well, and the sum of all the angles in a triangle is 180 degrees. So we have the equation:
(3x)3= 180
9x= 180
X =20
Solve the inequality. Graph the solution. 3(-b - 5) < -3
Answer:
The answer is (B)
Step-by-step explanation:
Hope it works
Cant figure it out pls help
5y = -3x + 7
y = -3/5x + 7/5
Parallel = same slope
y = -3/5x + b
3 = -3/5 + b, b = 18/5
Standard form: Ax + By = C
y = -3/5x + 18/5
-3/5x - y = -18/5
Multiply by -5
Solution: 3x + 5y = 18
Answer: Scale factor = 2
This is the same as writing [tex]\frac{2}{1}[/tex]
===============================================
Explanation:
Focus on the left sides of each triangle. They correspond to one another. Note how RS represents the first two letters of RST; while MN represents the first two letters of MNO. We can see the order matters.
To find the scale factor, we divide MN over RS to get
MN/RS = 6/3 = 2
Therefore, the sides of triangle MNO are 2 times longer compared to the sides of triangle RST.
------------------------
Extra info:
If you want to find x, then you would solve the following
MN/RS = ON/TS
6/3 = x/5.5
6*5.5 = 3x
33 = 3x
3x = 33
x = 33/3
x = 11
or we could simply multiply ST = 5.5 by the scale factor 2 getting 5.5*2 = 11, which is the length of segment ON.

Find the slope of the line that passes through (-7, 1.3) and (-7, 14.2)
Answer:
The slope of the line that passes through (-7, 1.3) and (-7, 14.2) is undefined.
Step-by-step explanation:
Given the points
(-7, 1.3)(-7, 14.2)Finding the slope between (-7, 1.3) and (-7, 14.2):
It is clear that the value of x-coordinate remains the same, no matter what is the value of y is.
In other words, the given line is vertical.
i.e. [x₂ - x₁] = -7 - (-7) = -7+7 = 0
We know that the slope of a vertical line is undefined.
i.e.
Using the slope formula
Slope = [14.2 - 1.3] / [0]
Hence, the slope of the line that passes through (-7, 1.3) and (-7, 14.2) is undefined.
