Step-by-step explanation:
Hope this helps give brainlest plz
The exponential function for the sequence in which the explicit formula for geometric sequence is f(n)=525(20)^n-1, is f(n)=(525/20)(20)ⁿ.
What is geometric sequence?Geometric sequence is the sequence in which the next term is obtained by multiplying the previous term with the same number for the whole series.
The explicit formula geometric sequence is given as,
[tex]f(n)=a(r)^{n-1}[/tex]
Here, a is the first term and r is the common ratio.
The explicit formula for a certain geometric sequence is,
[tex]f(n)=525(20)^n-1[/tex]
Compare it with above equation, we get,
[tex]a=525\\r=20[/tex]
The form of exponential function is,
[tex]f(n)=\dfrac{a}{r}(r)^n[/tex]
Put the values,
[tex]f(n)=\dfrac{525}{20}(20)^n[/tex]
Thus, the exponential function for the sequence in which the explicit formula for geometric sequence is f(n)=525(20)^n-1, is f(n)=(525/20)(20)ⁿ.

1) 2
2) 4
3) 1
Answer:
A = (1, 4)
Step-by-step explanation:
Given :
Square numbers include : 1², 2², 3², 4²,...
x|x square numbers less than 5
1² = 1
2² = 4
3² = 9 (not applicable)
Square numbers less than 5 are ; 1, 4
Hence,
Set A = (1, 4) where, x|x square numbers less than 5

Delilah deposits $8,255 in an account that pays 4.2% simple interest. How much money will be in her account after 8 years?
A.$2,773.69
B.$11,028,68
C.$12,254,66
D.$27,736,80
Answer:
$11,028.68
Step-by-step explanation:
As we all know, the simple interest formula is as follows:
[tex]P(1+rt)[/tex]
Wherein:
P = Principal amount
r = rate (in percentage so, rate/100)
t = time (in years)
Hence, when we substitute in these values,
[tex]8255(1+(4.2/100)*8)[/tex]
= $11,028,68
it will be 4.2/100 as it is percentage form.
Solve for x. Round to the nearest tenth, if necessary.

The answer is 8
Step-by-step explanation:
By using the theory of Euclid

Step-by-step explanation:
. CDEF is a trapezium
. ABCF is a rectangle
. BD = 9cm
. AB = 6cm
. EF = 3cm
. perimeter of ABCF = 20cm
9514 1404 393
Answer:
24 cm²
Step-by-step explanation:
To find the area of the trapezium, we must know the length CD. That means we must know the length BC. Fortunately, the perimeter of ABCF is given, so we have ...
P = 2(AB +BC)
BC = (P/2) -AB = (20 cm)/2 - 6 cm = 4 cm
Then CD is ...
CD = BD -BC = 9 cm -4 cm = 5 cm
The area of the trapezium is given by the formula ...
A = (1/2)(b1 +b2)h
A = (1/2)(5 cm + 3 cm)(6 cm) = 24 cm²
The area of trapezium CDEF is 24 cm².

A farmer harvested 1,760 pieces of fruit. 65% of them were not oranges. How many oranges did the farmer harvest?
Answer:
Number of oranges= 616
Step-by-step explanation:
Giving the following information:
A farmer harvested 1,760 pieces of fruit. 65% of them were not oranges.
To calculate the number of oranges, we need to use the following formula:
Number of oranges= total number of fruits*percentage of oranges
Number of oranges= 1,760 * (1 - 0.65)
Number of oranges= 616

Solve the equation 2 = -6 – 20x for x.
Answer:
x = - 2/5
Step-by-step explanation:
1.) add six on both sides, the six on the right will cancel out
2.) divide both sides by -20
3.) this will cancel the -20 on the right out which will give your answer for x on the left side
therefore, x should equal - 2 / 5 once simplified

30 points!!! The polygons in each pair are similar. Find the scale factor of the smal
figure to the larger figure. Write scale factor with a : (ex. 1:7) *
Answer:
5:6
Step-by-step explanation:
20:24 or 5:6
The scale factor of the small figure to the larger figure is in the ratio 6:5.
The scale factor can be calculated by dividing the smaller figure to the larger figure in each pair of polygons,
It can be obtained by dividing the corresponding side lengths of the smaller figure by the corresponding side lengths of the larger figure.
The scale factor for the side 42 and 24 will be :
Scale factor of the smaller figure to the larger figure = [tex]\dfrac{42}{35}[/tex]
In the lowest form, it becomes [tex]\dfrac{6}{5}[/tex]
So, the scale factor is 6:5.
The scale factor for the side 24 and 20 will be:
Scale factor of the smaller figure to the larger figure =[tex]\dfrac{24}{20}[/tex]
In the lowest form, it becomes [tex]\dfrac{6}{5}[/tex]
So, the scale factor is 6:5.
Therefore, the scale factors for each pair are 6:5.

slove: x = 3y - 7

show steps
Answer:
1.1 Solve x-3y+7 = 0
recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).
"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.
In this formula :
y tells us how far up the line goes
x tells us how far along
m is the Slope or Gradient i.e. how steep the line is
b is the Y-intercept i.e. where the line crosses the Y axis
The X and Y intercepts and the Slope are called the line properties. We shall now graph the line x-3y+7 = 0 and calculate its properties

Answer: Solution: (-4, 1)
Step-by-step explanation:
x = 3y - 7
4x + 5y = -11
Substitute x for 3y - 7
4x + 5y = -11
4 (3y - 7) + 5y = -11
12y - 28 + 5y = -11
17y - 28 = -11
Add 28 to both sides
17y = 17
y = 1
x = 3y - 7
x = 3(1) - 7
x = 3 - 7
x = -4
Solution: (-4, 1)

Answer:
Check pdf
Step-by-step explanation:
What is the equation of the line with a slope of 2 through (-4, 6) in point-slope form?
O y = 2x + 14
Oy-6 = 2 (x +4)
Oy= 2x – 14
Oy+6 = 2 (x – 4)
Answer:
y - 6 = 2(x + 4)
Step-by-step explanation:
Point slope form is y - [tex]y_{1}[/tex] = m (x - [tex]x_{1}[/tex]).
[tex]x_{1}[/tex] and [tex]y_{1}[/tex] are the points that they give you in the problem, which is (-4, 6), and m is the slope, which is 2.
When you plug everything in, you should get
y - 6 = 2(x + 4).
