How do you simplify 5 to the 3 power times 25
Answers
Answer:
5^5
Step-by-step explanation:
5^3 * 25
Note that 25 = 5^2 (which is 5 * 5)
so we can rewrite the first expression as
5^3 * 5^2
We can add the exponents because we are multiplying and there is the same base (5):
5^(3+2) = 5^5

To graph an exponential,

What is mean by graph?The set of ordered pairings (x, y) where f(x) = y makes up the graph of a function.
These pairs are Cartesian coordinates of points in two-dimensional space and so constitute a subset of this plane in the general case when f(x) are real values.
Now,
We know an exponential function is a function in which the independent variable is the exponent.
One such function is y = eˣ
Now, To graph an exponential function you come up with values to use in the graph should be a T-chart using random values for x and y.
As it would result in graphing the complete nature of the function.

Answers
Part A
Answer: x = 20--------------------------------
Explanation:
AP = arithmetic progression, which is another way of saying arithmetic sequence.
Let d = common difference
first term = 10second term = first+d = 10+d = xthird term = second+d = x+d = 30Apply substitution like so
x+d = 30
10+d+d = 30 ... replaced x with 10+d
10+2d = 30
2d = 30-10
2d = 20
d = 20/2
d = 10 is the common difference
Therefore,
x = 10+d = 10+10 = 20
The AP {10,x,30} updates to {10,20,30}. We see the gap between terms is 10 units. All AP's have the same gap width between adjacent terms.
=============================================================
Part B
Answers: x = 10 and y = 14--------------------------------
Explanation:
We use the same ideas mentioned back in part A.
d = common difference = unknown for now
first term = 6second term = first+d = 6+d = xthird term = second+d = x+d = (6+d)+d = 6+2d = yfourth term = third+d = y+d = (6+2d)+d = 6+3d = 18Hopefully you can see how each term builds up to form the next one. We'll solve that last equation like so
6+3d = 18
3d = 18-6
3d = 12
d = 12/3
d = 4
So we then can say:
x = 6+d = 6+4 = 10y = 6+2d = 6+2(4) = 6+8 = 14The arithmetic sequence {6,x,y,18} updates to {6,10,14,18}. There's a gap of 4 between each adjacent term.

If you deposit $5000 into an account paying a rate 15% simple interest annually, how much interest will you make in 24 months
Answers
Answer:
1500
Step-by-step explanation:
24 month means 2 years ( N )
rate 15 pcpa ( R )
amount is 5000 ( P )
so by formula
interest = P×N×R/100
so ( I ) = 5000×2×15/100
so( I ) = 50×2×15 ....... ( here 100 ( 2 zero ) and 5000.( 2 zero ) got canceled
so ( I ) = 50×2×15
so ( I ) = 100×15
so ( I ) = 1500

B. 1; –64; –16,384
C. –8; –64; –1,024
D. –2; –16; –256
Answers
Answer:
D
Step-by-step explanation:
given that
A(n)=-2•2^(n-1)
n->represent the terms
A(1)=-2•2^(1-1)=>-2•2^0
A(1)=-2•1=-2
For the fourth term
A(4)=-2•2^(4-1)
A(4)=-2•2^(3)
A(4)=-16
for the 8th term
A(8)=-2•2^(8-1)
A(8)=-2•2^(7)
A(8)=-256
Therefore first, fourth and eight => -2;-16;-256

10x^3, 40x^8, 160x^13,…
Answers
Answer:
[tex]a_7=40960x^{33}[/tex]
Step-by-step explanation:
Geometric sequence has explicit form:
[tex]a_n=a \cdot r^{n-1}[/tex] where [tex]a[/tex] is first term and [tex]r[/tex] is the common ratio.
First term here is [tex]a=10x^3[/tex] and [tex]r[/tex] could be found by doing second term divided by first term, [tex]\frac{40x^8}{10x^3}=4x^5[/tex].
Therefore the [tex]n[/tex]th term is given by
[tex]a_n=10x^3 \cdot (4x^5)^{n-1}[/tex].
So the [tex]7[/tex]th term is given by
[tex]a_7=10x^3 \cdot (4x^5)^{7-1}[/tex].
Let's simplify:
[tex]a_7=10x^3 \cdot (4x^5)^{7-1}[/tex]
[tex]a_7=10x^3 \cdot (4x^5)^{6}[/tex]
[tex]a_7=10x^3 \cdot (4^6(x^5)^6)[/tex]
[tex]a_7=10x^3 \cdot (4096x^30)[/tex]
[tex]a_7=40960x^{33}[/tex]

Answers
Answer: London and Moscow.
Step-by-step explanation: This problem is simple. First, we use process-of-elimination. None of the positive values have a difference of 25 degrees, so one of the two values must be -12 degrees aka Moscow. From there, we add 25 to -12 to get 13. This means that the other city is London since it is 13 degrees.

Two mechanics worked on a car. The first mechanic worked for 10 hours, the second mechanic worked for 5. Together they charged a total of 950$ What was the rate charged per hour by each mechanic if the sum of the two rates was 125$ per hour?
Answers
Answer:
Step-by-step explanation:
Let x = the hourly rate of the first mechanic and
y = the hourly rate of the second mechanic.
As far as the equation goes for the total amount charged:
10x + 5y = 950
As far as the equation goes for the sum of the 2 mechanics' rates:
x + y = 125
Solve the first equation for either x or y. I solved for y:
y = 125 - x
Now plug that into the first equation for y to get:
10x + 5(125 - x) = 950 and
10x + 625 - 5x = 950 and
5x = 325 so
x = 65
The first mechanic charges $65 per hour and the second mechanic charges
y = 125 - 65 so
the second mechanic charges $60 per hour.

What load can be lifted by an effort of 800N if the effort arm is 80cm and the load arm is 20cm?
Answers
Step-by-step explanation:
Solution,
Effort=800N
Effort arm=80 cm
Load arm=20 cm
Load=?
Now,
by the principle of lever, we have
Load×Load arm=Effot×Effort armLoad×20=800×80Load=800×80/20Load=3200 NSo, the load of 3200N can be lifted .
Answer:
load (l) =?
LOAD ARM = 20 CM
EFFORT ( E)= 800N
EFFORT ARM = 80cm
load *load arm = effort *effort arm
l*20 cm = 800 *80
L = 64000/20
answer = 3200
