A rock is dropped from a sea cliff, and the sound of it striking the ocean is heard 3.4 s later. if the speed of sound is 340m/s how high is the cliff?

Answers

Answer 1
The total time of 3.4 seconds includes the time the rock falls and the time it takes for the sound wave to return to the top of the cliff.

Where d is the height of the cliff in meters, the falling time is

=29.8‾‾‾√
t
f
=
2
d
9.8

... and the sound wave return time is

=340
t
s
=
d
340

We need to set the sum of those two components to 3.4 sec and solve.

3.4=+
3.4
=
t
f
+
t
s

3.4=29.8‾‾‾√+340
3.4
=

d

+
d
340

Not a pretty formula. I found d =51.69+
51.69
+
meters using goal seek. At that height, the rock would fall for 3.25 seconds, and the sound would return in 0.15 seconds, for a total time of 3.40 seconds.

Which equation is y = 6x2 + 12x – 10 rewritten in vertex form? y = 6(x + 1)2 – 11 y = 6(x + 1)2 – 10 y = 6(x + 1)2 – 4 y = 6(x + 1)2 – 16

Explanation:bc irdk

y = 6(x + 1)2 – 11 y = 6(x + 1)2 – 10 y = 6(x + 1)2 – 4 y = 6(x + 1)2 – 16.

What is Vertex form?

There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions.

For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, which are separated by the 'equal' sign. Mathematical algebraic equations typically have one or more variables.

Equations are frequently utilized in daily life, but they are most frequently used in science and numerous math applications. For instance, a grocery store can apply an algorithm to determine the price of an item that is 50% discounted.

Therefore, y = 6(x + 1)2 – 11 y = 6(x + 1)2 – 10 y = 6(x + 1)2 – 4 y = 6(x + 1)2 – 16.

There are 12 of the zodiac. how many people are needed to guarantee that at least six of these people have the same sign? your answer must be one integer.

Answers

Answer:es, the answer is 61. This is related to a mathematical principle called the Pigeonhole Principle, which states that if you are trying to sort  n+1  objects into k sets (where nk=r;n,k,r∈Z+), at least one set must contain at least r+1 objects. (This can be proven by proof by contradiction, but is pretty standard and so generally can just be used as justification of an answer by itself.)

For your problem, you have 12 signs of the zodiac - these are your 12 sets (so k=12). You are looking to find how many it takes before a set contains 6 objects (so r+1=6 and thus r=5). Therefore, n+1=r×k+1=12×5+1=61.

What is the equation of the line that passes through the point (-1,9) and is parallel to the line y=-5x+7?

Answers

Answer:

Y=5x+14

Explanation:

here, x=-1 y= 9

the equation of the line in slope intercept form is

y=mx+b

the slope(m)= 5

y intercept (b)= 7

note that slope of parallel lines are the same

then the equation

y= mx+b

substituting

9= 5(-1)+b

9 = -5+b

9+5 =b

14 = b

b= 14

therefore, y intercept of the parallel line will be 14.

finally, the equation of the parallel line will be

Y= 5x+14

What is the ph of a solution made by mixing 30.00 ml of 0.10 m acetic acid with 50.00 ml of 0.100 m koh? assume that the volumes of the solutions are additive. k a = 1.8 × 10-5 for ch3co2h.

Answers

Given 30.00 ml of 0.10 m acetic acid and 50.00 ml of 0.100 m koh, the pH of the solution is 12.40

What is the pH of a substance?

This is the measure of the acidity or the basicity of an aqueous or liquidsolution.

The details that are contained in this question are:

Mole of CH3COOH = 0.1 M

Volume of CH3COOH  = 30 mL

Mole of KOH = 0.1 M

Volume of KOH = 50 mL

mol of (CH3COOH) = 0.1 Mole * 30 mL = 3 mol

mol of (KOH) = 0.1 Mole * 50 mL = 5 mol

From the solution above,

mol of CH3COOH = 3 mol

mol of KOH = 5 mol

3 mol of both substances is going to react

excess KOH remaining = 5 - 3 =  2 mmol

Volume of both Solutions

= 30 + 50 = 80 mL

OH⁻ = 2/80

= 0.025 M

use:

pOH = -log [OH-]

= -log (0.025)

pOH = 1.602

PH = 14 - pOH

= 14 - 1.60

= 12.40

The calculated pH is therefore 12.40
