Therefore , the solution of the given problem of area comes out to be AB/DC =5 Imagine that your square is made out of more compact unit squares.
What is area?Area is the quantity that describes how much space .A surface or an object's shape occupy. Use a pencil to mark a square on the paper. Specifically, a 2-D figure. A shape's area on paper is referred to as its "Area" in this sentence. Imagine that your square is made out of more compact unit squares.
Since the heights of both trapezoids are equal, and the area of ABEF is twice the area of FECD, AB+ EF/2 = 2(DC+EF /2) AB + EF / 2= DC + EF,
AB + EF = 2DC + 2EF. EF is exactly halfway between AB and DC, so EF = AB + (AB+ DC)/2 = 2DC+ AB + DC, so 3/2 AB + 1/2DC = 3DC+AB, 1/2AB =5/2DC => AB/DC =5 Therefore , the solution of the given problem of area comes out to be AB/DC =5.

Answer:
☆ Emily has $16 more
Step-by-step explanation:
FOR JAXON:
You want to calculate the interest on $600 at 2.5% interest per year after 3 year(s).
The formula we'll use for this is the simple interest formula, or:
Where:
P is the principal amount, $600.00.
r is the interest rate, 2.5% per year, or in decimal form, 2.5/100=0.025.
t is the time involved, 3....year(s) time periods.
So, t is 3....year time periods.
To find the simple interest, we multiply 600 × 0.025 × 3 to get that:
The interest is: $45.00
Usually now, the interest is added onto the principal to figure some new amount after 3 year(s),
or 600.00 + 45.00 = 645.00.
Jaxon will have $645 after he closes his account.
FOR EMILY
You want to calculate the interest on $600 at 5.1% interest per year after 2 year(s).
The formula we'll use for this is the simple interest formula, or:
Where:
P is the principal amount, $600.00.
r is the interest rate, 5.1% per year, or in decimal form, 5.1/100=0.051.
t is the time involved, 2....year(s) time periods.
So, t is 2....year time periods.
To find the simple interest, we multiply 600 × 0.051 × 2 to get that:
The interest is: $61.20
Usually now, the interest is added onto the principal to figure some new amount after 2 year(s),
or 600.00 + 61.20 = 661.20.
Emily will have $661 when she closes her account.
☆ Therefore, Emily will have $16 more than Jaxon.

What is cell body?The soma, or cell body, is the spherical part of the neuron that houses the nucleus. The cell body is linked to the dendrites, which transport information to the neuron, and the axon, which sends information to other neurons.
When one neuron receives information from another, the dendrites send it to the cell body. Depending on the signal strength, the cell body may then send the information to the axon.
The cell body's role is to regulate all of the cell's functions. It has several important organelles that aid in this process. Organelles are tiny organelles found within cells that each perform a specific function. The nucleus is the most important organelle within the cell body.

For problems 1 - 6, determine whether the relationships represented are A. Exponential., B. Linear., or C. Neither.
Step-by-step explanation:
a linear function is following
y = ax + b
that means the ratio of the y and x differences between the data points is constant (a).
an exponential function is in the form y = a^x. or some constant variations of it.
the base is constant (a), and the exponent of the constant is the variable (x).
1.
clearly exponential.
this is the typical graph of an exponential function.
it looks like y = 2^x, as e.g. f(4) = 2⁴ = 16, and the graph seems to be at least very close to this.
2.
exponential.
y = 3^(x - 0.5)
3¹ = 3
3² = 9
3³ = 27
3⁵ = 243
this is just y = 3^x shifted to the right by 0.5 units.
3.
linear.
the difference ratio between the data points is constant :
x is the row number (1, 2, 3, 4, 5, ...).
y is the number of seats per row (14, 16, 18, 20, 22, ...).
so,
(16-14)/(2-1) = 2/1 = 2
(18-16)/(3-2) = 2/1 = 2
...
(22-14)/(5-1) = 8/4 = 2
always constant (2).
4.
neither.
it is y = x²
when you compare 4. and 1. you see the clear difference between the 2 graphs.
5.
exponential.
remember, y = a^x.
well, here, a = 1/2. but that is still constant and doesnot change the principle.
the factor 10 stretches the graph a bit up (in fact, this 10 is the starting number of an exponential growth). but the function in its core is still exponential.
6.
linear.
when written that way, it just means that x = n, and for every increase of n by 1, y (f(n)) increases by +4.
so, the difference ratio stays constant (4/1 = 4).
Rule 1: Multiply by 2, then add 1/3 starting from 1. Rule 2: Add 1/2, then multiply by 4 starting from 0. What is the fourth ordered pair using the two sequences
Answer:
(10 1/3, 42)
Step-by-step explanation:
a1 = 1
a2 = a1×2 + 1/3 = 2 1/3
a3 = a2×2 + 1/3 = (a1×2 + 1/3)×2 + 1/3 = a1×4 + 2/3 + 1/3 =
= 4 + 3/3 = 5
a4 = a3×2 + 1/3 = ... = 10 1/3
b1 = 0
b2 = (b1 + 1/2)×4 = (0 + 1/2)×4 = 1/2 × 4 = 2
b3 = (b2 + 1/2)×4 = ((b1 + 1/2)×4 +1/2)×4 = 16×b1 + 16/2 + 4/2=
= 16/2 + 4/2 = 8 + 2 = 10
or (to check we made no mistake)
= (2 + 1/2)×4 = 8 + 2 = 10. => all ok, no mistake
b4 = (b3 + 1/2)×4 = ... = (10 + 1/2)×4 = 40 + 2 = 42
so, the fourth ordered pair (= the fourth elements of each sequence) is therefore (10 1/3, 42)
