c. Acidity/Alkalinity

d. Compound Interest

e. Amortization Schedule

Answer:

The correct two options are;

b. Richter Scale

c. Acidity/Alkalinity

Step-by-step explanation:

Here we have

b. The Richter Scale, given by the following relation;

[tex]M = log(\frac{I}{I_0} )[/tex]

M = Earth quake magnitude

I = Earthquake intensity

I₀ = Earthquake intensity of magnitude 0

Comparing two Earthquakes, A and B, we have

[tex]M_A - M_B = log(\frac{I_A}{I_B} )[/tex]

c. Acidity/Alkalinity are determined by the pH of the solution, which is the negative logarithm of the hydrogen ion concentration

pH = -log₁₀ [H⁺].

The magnitude of the first duckling's displacement is 13 units, and for the second duckling it is approximately 15.3 units. The second duckling wandered 2.3 units farther than the first.

The student is asking about the displacements of two ducklings from their nest and how much farther one wandered than the other. To compare the displacements of the two ducklings, we calculate the magnitudes of their displacements using the Pythagorean theorem.

For the first duckling's displacement, with coordinates (12,5), the magnitude is
sqrt(122 + 52) = sqrt(144 + 25) = sqrt(169) = 13 units.

For the second duckling's displacement, with coordinates (13,-8), the magnitude is
sqrt(132 + (-8)2) = sqrt(169 + 64) = sqrt(233) = approximately 15.3 units.

The second duckling wandered farther by the difference in magnitudes, which is 15.3 units - 13 units = 2.3 units. Therefore, the second duckling wandered 2.3 units farther than the first duckling.

Answer:

Mark types the fastest rate of words per minute at 75 words per minute

Step-by-step explanation:

In this question, we want to know which of the three typists has the fastest typing rate.

To calculate this, what we need to do is to divide the total number of words they can type by the number of minutes taken to type those words.

For Natasha, we have; 2600 words / 40 minutes = 65 words per minute

For Henry, we have 4900 words/70 minutes = 70 words per minute

For Mark, we have 3750 words/50 minutes = 75 words per minute

We can see that Mark with 75 words per minute has the fastest typing rate

Answer:

[tex]28.8\%[/tex].

Step-by-step explanation:

We have been given that prices  increase  at  a  monthly  rate  of  2.4%. We are asked to find the percentage at which prices will increase in a year.

We know that 1 year equals 12 months.

To find the increase in one year, we will multiply monthly increase rate by 12 as:

[tex]\text{Yearly increase rate}=12\times 2.4\%[/tex]

[tex]\text{Yearly increase rate}=28.8\%[/tex]

Therefore, the prices will increase at a rate of [tex]28.8\%[/tex] in a year.

Answer: 9.16 feet

Step-by-step explanation:

Hi, to answer this question, since we have formed a right triangle (see attachment) we have to apply the Pythagorean theorem:

a2 +b2 = c2

Where c is the hypotenuse of a right rectangle (the longest side) and a and b are the lengths of the other 2 sides.

In this case the hypotenuse us the ladder.

So, replacing with the values:

4^2 + b ^2 = 10^2

16 + b^2 = 100

b^2 = 100-16

b^2 = 84

b = √84

b= 9.16 feet

Step-by-step explanation:

Please kindly check the attached file for explanation

Answer: The probability of picking a green block or red block is 0.64 (or 64%)

Step-by-step explanation: The total number of blocks can be derived as;

31 (R) + 49(G) + 24(Y) + 21(P) = 125

With 125 blocks in total, there are 125 possibilities and the possibility of picking any of the four colors shall be be determined as a fraction of the entire possible outcomes.

The probability of picking a green ball when picked at random is given as;

P(Green) = Number of required outcomes ÷ Number of all possible outcomes

P(Green) = 49/125

(Note that there are 49 green blocks and a total of 125 blocks of all four colors)

Also the probability of picking a red ball when picked at random is given as;

P(Red) = Number of required outcomes ÷ Number of all possible outcomes

P(Red) = 31/125

The probability of picking a green block or a red block is given as P(green or red)

P(Green or Red) = 49/125 + 31/125

P(Green or Red) = 80/125

P(Green or Red) = 16/25

P(Green or Red) = 0.64

Therefore the probability of picking a green or red block at random is 0.64 or 64%

If you plug it all in you will get x=2 x=-3

Step-by-step explanation:

The quadratic formula is

-b+/-[tex]\sqrt[/tex]-b^2-4ac all over 2(a)

your equation 2x^2+2x-12

you can label it

a=1      b=2               c=-12

If you plug it all in and solve you will get x=2 x=-3

The values of x would be 2 and 3 which are determined by using the quadratic formula to solve the given quadratic function.

The quadratic function is defined as a function containing the highest power of a variable is two.

We have been given that quadratic function as

2x² + 2x - 12

Compare the given function to the standard quadratic function f(x) = ax² + b x + c.

We get a = 2, b = 2 and c = -12

Using the quadratic formula to solve the above quadratic function

[tex]x = \dfrac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]

Substitute the values of  a = 2, b = 2 and c = -12 in the quadratic formula,

[tex]x = \dfrac{-2\pm\sqrt{2^2-4\times2\times-12}}{2\times2}[/tex]

[tex]x = \dfrac{-2\pm\sqrt{4+96}}{4}[/tex]

[tex]x = \dfrac{-2\pm\sqrt{100}}{4}[/tex]

[tex]x = \dfrac{-2\pm10}{4}[/tex]

x = (-2+10)/4 and x = (-2-10)/4

x = (8)/4 and x = (12)/4

x = 2 and x = 3

Therefore, the values of x would be 2 and 3 which are determined by using the quadratic formula to solve the given quadratic function.

Answer:

Step-by-step explanation:

We would section the bread into a cuboid at the bottom and a semi cylinder at the top.

Considering the bottom, the formula for determining the volume of a cuboid is expressed as

Volume = length × width × height

Therefore,

Volume = 20 × 11 × 6 = 1320 cm³

Considering the semi cylinder,

The formula for determining the volume of a cylinder is expressed as

Volume = πr²h

Where

r represents the radius of the cylinder

h represents the height of the cylinder.

π = 3.14

Looking at the diagram,

Height = 20 cm

Diameter = 11 cm

Radius = diameter/2 = 11/2 = 5.5 cm

Since it is a semi cylinder, then

Volume = 1/2 × 3.14 × 5.5² × 20 = 949.85 cm³

Therefore, volume of this loaf of bread is

1320 + 949.85 = 2269.85 cm³

Answer:It would be A. $19x + $160 < $635

Step-by-step explanation:

A tangent line intersecting with a radius always creates a  right angle.

A tangent line intersects with a circle at only one point.

This point is referred to as the point of tangency.

When a radius is drawn to intersect with the tangent line at the point of tangency, then the angle at that point of intersection is a right angle i.e. the measure of the angle is 90 degrees.

This is so because both lines (i.e. the radius and the tangent line) are perpendicular lines.

Hence, the text that completes the statement is right angle.

Answer:

66 in total. 44 boys and 22 girls

Step-by-step explanation:

you have to multiply 22 by 2 because there is twice as many (half of two is one) boys than there is girls.

Answer:

66

Step-by-step explanation:

There is a 2:1 ratio of boys to girls, and there are 22 more boys than girls. We can assume that 2/3 of the class are boys while 1/3 of the class is girls.

The difference between the two is 1/3. This can be found by taking away the smaller of the two from the larger, in this case it's 2/3 - 1/3. Removing the third, it's 2-1 which can be done by multiplying the two fractions by three. If we add the third back by dividing by three, we get 1/3.

This means that 22 people must be equivalent to 1/3 the total class' population. If x/3 = 22, then 22 * 3 must be x.

22 * 3 = 66, so there must be 66 students in the class.

exponent to log: [tex]a^b[/tex] = c ---> logₐc = b

ie. question 6

log ₁₀(3x+1) = 2 -----> [tex]10^{2} = 3x+1[/tex]

that will get you through questions 1 to 3, 5 to 6, and 8

in question 4, all you have to do is know that 2^2 = 4 and 2^3 = 8, by setting the bases equal, you can manipulate the exponents to get 2x+8 = 3x-3

for questions 7 and 9,

remember that:

Answer:

The answer is C(n,r) = n!/[(n-r)!r!]

The formula for the following conditions is  [tex]C(n,r) = \dfrac{n!}{[(n-r)!r!]}[/tex]

We can use combinations for this case,

A total number of distinguishable things is m.

Out of those m things, k things are to be chosen such that their order doesn't matter.

This can be done in a total of

[tex]^mC_k = \dfrac{m!}{k! \times (m-k)!} ways.[/tex]

If the order matters, then each of those choice of k distinct items would be permuted k! times.

So, a total number of choices, in that case, would be:

[tex]^mP_k = k! \times ^mC_k = k! \times \dfrac{m!}{k! \times (m-k)!} = \dfrac{m!}{ (m-k)!}\\\\^mP_k = \dfrac{m!}{ (m-k)!}[/tex]

This is called the permutation of k items chosen out of m items (all distinct).
