The average temperature of the top 5 meters in April is 22,500 cubic meters. 2. Typical seawater has a salinity of 35 psu (practical salinity units). In which month is the difference in salinity of surface and bottom waters the greatest
The months where the difference in salinity of surface and bottom waters was the greatest was in April and September.
What is salinity?It should be noted that salinity simply means the accumulation of salt in land as well as water.
In this case, the months where the difference in salinity of surface and bottom waters was the greatest was in April and September.
This is because many events take place such as continuous flowing or river water into the sea, evaporation, and melting of ice.

Step-by-step explanation:
Hey there!
To put the numbers in least to greatest form, you need to put the biggest numbers with a - sign in front of it
This means negative
Negative means below zero
Then after putting the big negative numbers, you put positive numbers going from smallest to largest
So the numbers in least to greatest is -24, -21, -19, -19, -19, -14, -13, -12, -7, -3, 2, 5, 6, 11, 11, 15

A. x = }
B. x= -1
0 C. x= -3
D. x= 2
E. x = 3
Answer:
E. x = 3
Step-by-step explanation:
The equation can be factored by considering the factors of the product of the first and last coefficients. Those factors must have a sum equal to the middle coefficient.
(2)(-3) = -6 = (-6)(1) = (-3)(2) = ... other factors with positive sums
The sums of the factor pairs shown are -5 and -1. We're interested in the factor pair {-6, 1}. Replacing the middle term coefficient with the sum of these, we can write the equation in a way that lets us factor pairs of terms.
2x² -6x +x -3 = 0 . . . . . . . . replace -5x with -6x+1x
2x(x -3) +1(x -3) = 0 . . . . . . factor pairs of terms
(2x +1)(x -3) = 0 . . . . . . . . . complete the factoring
Solutions are the values of x that make these factors zero:
2x +1 = 0 ⇒ x = -1/2
x -3 = 0 ⇒ x = 3

Additional comment
A number of methods are used to find the factors of a quadratic with a leading coefficient other than 1. When the coefficients are small integers, this is one of the more straightforward methods: actually listing and examining the pairs of factors of "ac." If "ac" has a large number of divisors, other methods may be more practical.

Value (in billions) 2017 2018
Total assets $16. 20 $16. 80
Total liabilities $14. 60 $14. 80
Deposits $11. 90 $12. 20
From 2017 to 2018, borrowings by commercial banks changed by $ _ billion (round your answer to two decimal places).
From 2017 to 2018, owner’s equity for commercial banks changed by $_ billion (round your answer to two decimal places)
Answer:
Borrowings = $0.10 Billion
Owner's Equity = $0.40 Billion
Step-by-step explanation:
Total liabilities = deposits + borrowings
Borrowings = total liabilities - deposits
Borrowings in 2017 = $14.60 - 11.90 = $2.70 billion
Borrowings in 2018 = $14.80 - $12.20 = $2.60 billion
Borrowings from 2017-2018= 2.60 - 2.70 = $0.10 billion
Owner's Equity= total assets - total liabilities
Owner’s equity in 2017 = $16.2 - $14.6 = $1.6 billion
Owner’s equity in 2018 = $16.8 - $14.8 = $2 billion
Owner's Equity from 2017-2018= 2 - 1.6 = $0.4 billion
Hope this helps!
The Owner's Equity for commercial banks in 2017-2018 is $0.4 billion.
The given is,
Borrowings = $0.10 Billion
Owner's Equity = $0.40 Billion
What is the formula for the total liabilities?Total liabilities = deposits + borrowings
So we have Borrowings = total liabilities - deposits
Borrowings in 2017
= $14.60 - 11.90
= $2.70 billion
Borrowings in 2018
= $14.80 - $12.20
= $2.60 billion
Borrowings from 2017-2018
= 2.60 - 2.70
= $0.10 billion
Owner's Equity= total assets - total liabilities
Owner’s equity in 2017
= $16.2 - $14.6
= $1.6 billion
Owner’s equity in 2018
= $16.8 - $14.8
= $2 billion
Owner's Equity from 2017-2018
= 2 - 1.6
= $0.4 billion

Circle A has center of (2, 3) and a radius of 5, and circle B has a center of (1, 4) and a radius of 10. What steps will help show that circle A is similar to circle B?
Dilate circle A by a scale factor of 2.
Translate circle A using the rule (x + 1, y − 1).
Rotate circle A 180° about the center.
Reflect circle A over the y-axis.
Answer:
A
Step-by-step explanation:
To show that circle A is similar to circle B the step required is Dilate circle A by a scale factor of 2 option (A) is correct.
What is a circle?It is described as a set of points, where each point is at the same distance from a fixed point (called the center of a circle)
We have two circles:
Circle A has a center of (2, 3) and a radius of 5
Circle B has a center of (1, 4) and a radius of 10
The standard circle's equation can be written as:
(x - h)² + (y - k)² = r²
The equation for circle A:
(x - 2)² + (y - 3)² = 5²
The equation for circle B:
(x - 1)² + (y - 4)² = 10²
To show that circle A is similar to circle B:
It is required to perform the geometric transformation:
Dilate circle A by a scale factor of 2.
The radius of circle A is 5 units and after dilation by a scale factor of 2, the radius of the circle becomes 10 which is the radius of circle B.
Thus, to show that circle A is similar to circle B the step required is Dilate circle A by a scale factor of 2 option (A) is correct.

Step-by-step explanation:
First I will mark all the Information given to us:
Angle 1: 52 Degrees
Angle 2: 90 (Marked by the box) Degrees
Angle 3: 180-(90+52) Triangle Angle Sum Therom
Simplified Angle 3: 38 Degrees
Height: 10
Base: X
Hypo: ? (we will call this y)
In order to solve this problem we must use basic trig functions such as sin, cos and tan.
I will be applying sin for the degree measure of 52 as it is applicable there.
(Sin for refrence sin(angle measure)= side opposite to angle/hypo)
So this would be in our case:
Sin(52)=10/y
Simplify
y sin(52) = 10
y = 10/sin(52) (use a calculator make sure sin is in degrees not radians)
y=10/0.78801
y=12.69018 (We have our hypo value)
We can now apply a²+b²=c²
a²+10²=12.69018²
a²+100=161.040668432 (Calculator)
a²=61.040668432

The volume of a box is 124.4 in3. Find the volume of a larger, similarly shaped box that has a scale factor of 4. Round your answer to the nearest tenth.
Using the scale factor, the volume of the larger similar shaped box is 497.6in³.
What is a Scale Factor?A scale factor is simply the ratio of the corresponding sides of two similar objects. A scale factor of 4 simply means that the new shape is multiply four times the size of the original shape.
Given the data in the question;
Volume of original box V° = 124.4in³Scale factor SF = 4Volume of the larger box V = ?Since scale factor of 4 means that the new shape is multiply four times the size of the original shape.
Volume of the larger box V = V° × SF

What is the y-value of the vertex of the function f(x)=−(x+8)(x−14)?
Answer:
f(x) = -(x + 8)(x -14)
= -(x2 - 112 - 6x)
= -x2 + 6x + 112 --- (1)
We know the graph of an equation y = ax2 + bx + c where a ≠ 0 is a parabola. The parabola opens upwards if a > 0 and opens downwards if a < 0. The vertex of the parabola is the point where the axis and parabola intersect. Its x coordinate x = -b/2a and its y coordinate is found out by substituting x = -b/2a in the parabola equation.
The parabola given in the problem statement has a negative coefficient of x2 and hence it is a parabola which opens downwards. Also for the equation
a = -1, b = 6 and c = 112. Therefor the x-coordinate of the vertex is
x = -b/2a
= -(6)/[2(-1)]
= 3
Substituting the value of x = 3 in equation (1) we get,
Now y = -(3)2 + 6(3) + 112
= -9 + 18 + 112 = 121
So the vertex point coordinates are (3, 121) and the y value is 121.
