If no withdrawals were made from the accounts. The total interest earned at the end of 1 year is $230 and the percent interest for the total deposited is 5.75%.
How to find the total interest earned?a. Total interest earned :
Total interest earned = (0.02)($1000)+(0.07)($3000)
Total interest earned =$20+$210
Total interest earned =$230
b. Percent interest amount deposited
Percent interest amount deposited = Total interest earned / Total amount deposited
Percent interest amount deposited = $230 /( $1,000 + $3,000)
Percent interest amount deposited = $230 / $4000
Percent interest amount deposited = 0.0575 × 100
Percent interest amount deposited =5.75%
Therefore $230 is the interest earned and 5.75 is the percent interest.

What is Geometric Series?
The total of a geometric sequence's finite or infinite terms is known as a geometric series. The analogous geometric series is a + ar + ar2 +..., arn-1 + for the geometric sequence a, ar, ar2,..., arn-1,... The word "series" is known to mean "sum." The geometric series specifically refers to the total of phrases with a common ratio between every pair of neighboring terms. Geometric series can be of two different types: finite and infinite.
In the given question, we have:
The series: 3 + 12 + 48 +
So, here the first term (a) = 3;
The second term = +12;
and, we know that the common ratio in the geometric series is the ratio of the second term and the first term.
So,
Common ratio, r = [tex]\frac{12}{3}[/tex]
r = 4;
so, The common ratio will be the same everywhere. So, It will be 4 in all the cases.
And, The first term, a is 3;

The consider the angle a
The equation will be
∠a + 312 = 360 degrees
∠a = 360 - 312
∠a = 48 degree
The angle a is less than 90 degrees then it is an acute angles
Consider the angle b
∠b + 220 = 360
∠b = 360 -220
∠b = 140 degrees
Angle b is greater than 90 degrees and less than 180 degrees then it is an obtuse angle
Consider the angle c
∠c + 36 = 360

Suppose you know that f(x) is an odd function on the domain of all real numbers and that the function is concave up on the intervals 0 < x < 3 and 5 < x and concave down on the interval 3 < x < 5.
List ALL intervals on which the function f(x) is concave up and ALL intervals on which the function f(x) is concave down; explain how you know these to be correct
The intervals for the concavity of the odd function are given as follows:
Concave down: x < -5, -3 < x < 0, 3 < x < 5.Concave up: -5 < x < -3, 0 < x < 3, x > 5.What are even and odd functions?The definition of even and odd functions depends on the relation between f(x) and f(-x), as explained as follows:
In even functions, we have that the statement f(x) = f(-x) is true for all values of x.In odd functions, we have that the statement f(-x) = -f(x) is true for all values of x.If none of the above statements are true for all values of x, the function is neither even nor odd.In this problem, we have that the function is odd, hence the following statement is true:
f(-x) = -f(x) for all values of x.
This means that the concavity intervals are exchanged, hence:
f(x) is concave down on -3 < x < 0, as it is concave up of 0 < x < 3.f(x) is concave down on x < -5, as it concave up on x > 5. f(x) is concave up on -5 < x < -3, as it is concave down of 3 < x < 5.More can be learned about even and odd functions at https://brainly.com/question/13048723

Triangle EFG is similar to triangle HIJ. Find JH. Round your answer to

The length of the side JH in the triangle ΔHIJ is 97.9.
We are given two triangles. The vertices of the first triangle are E, F, and G. The vertices of the second triangle are H, I, and J. The triangles ΔEFG and ΔHIJ are similar to each other. The lengths of the sides FG, GE, and IJ are 12, 25, and 47, respectively. We need to find the length of the side, JH. The figure of the triangles is attached below.
Let the length of the side JH in the triangle ΔHIJ be represented by the variable "x". The side IJ is proportional to the side FG. Let the constant of proportionality be "k".
IJ ∝ FG
IJ = k*FG
k = IJ/FG
k = 47/12
The side JH is proportional to the side GE.
JH = k*GE
x = (47/12)*25
x = 97.9
Hence, the length of the side JH is 97.9 units.

José is climbing a mountain. Using a rope, José climbs down from the top of a steep cliff for 4 minutes at a rate of 12.2 feet per minute. He then climbs back up for 10 minutes at a rate of 3.6 feet per minute. How far from the top of the cliff is he after 14 minutes?
Enter the correct answer in the box.
Please help this is due tomorrow
The distance from the top of the cliff that Jose is after 14 minutes is 12.8 feet downward.
What is an elevation?An elevation simply means the height above sea level.
In this case, José climbs down from the top of a steep cliff for 4 minutes at a rate of 12.2 feet per minute. The total feet will be:
= 12.2 × 4
= 48.8 feet
He then climbs back up for 10 minutes at a rate of 3.6 feet per minute. This will be:
= 3.6 × 10
= 36 feet.
Therefore, the change in elevation will be:
= Elevation up - Elevation down
= 36 - 48.8
= 12.8 feet.

Therefore, the angle relationship can be used to find the value of x and y in the diagram.
In the diagram, l and m are parallel lines and are cut by a transversal line.
Therefore,

By using the graphing method, an ordered pair which represent a solution to the given system of equations is (-6, -6).
What is a graph?A graph simply refers to a type of chart that is typically used for the graphical representation of data points or ordered pairs on both the horizontal and vertical lines of a cartesian coordinate, which are the x-axis and y-axis respectively.
In order to plot the system of equations on a graph, we would simplify the second equation as follows:
4u = 2v - 12
Dividing both sides of the equation by 4, we have the following:
4u/4 = 2v/4 - 12/4
u = v/2 - 3
Note: The values of v would be plotted on the y-axis of a graph while the values of u would be plotted on the y-axis of a graph.

The measurement of angles ∠1 is 126° and ∠2 is 154°.
According to the question,
We have the following information:
We have a figure of two triangles and some of the measurements of the angles are given.
We know that the sum of three angles of a triangle is 180°.
So, for the larger triangle, we have the following expression:
96+30+third angle = 180
Third angle = 180-126
Third angle = 54°
We know that sum of angles on a straight line is 180°.
So, we have:
∠1+54 = 180
∠1 = 180-54
∠1 = 126°
Now, finding the sum of angles in smaller triangle:
126+28+third angle = 180
Third angle = 180-154
Third angle = 26°
Now, angle 2 and this angle will make a straight line.
∠2+26 = 180
∠2 = 180-26
∠2 = 154°
Hence, the measurement of angles ∠1 is 126° and ∠2 is 154°.
