The monomial -0.01a^4*(-10a^5)^3 as a single expression is 10a^19
How to rewrite the expression?The expression is given as
-0.01a^4*(-10a^5)^3
Evaluate the expression in the bracket
So, we have the following equation
-0.01a^4*(-10a^5)^3 = -0.01a^4 * (-1000a^15)
Next, we remove the bracket
So, we have the following equation
-0.01a^4*(-10a^5)^3 = 0.01a^4 * 1000a^15
Evaluate the products in the above equation
So, we have
-0.01a^4*(-10a^5)^3 = 10a^19
Hence, the equivalent expression is 10a^19

a company has its employees choose a password which consists of 9 characters: 3 letters, followed by 2 symbols, followed by 4 digits. there are a total of 11 symbols that the employees can choose from. letters, symbols and digits can be repeated. how many possible passwords are there?
The total possible choices of password that are available is 21,266,960,000.
The length of the password has to be of 9 characters.
Three of them should be letters, 2 should be symbols from the 11 choices of the symbols and 4 have to be digits.
Any of the following can be repeated in the password,
So, making the combination of 9 characters.
As we know, letters are 26, so, there are 26 choices each for three places.
Also, if 11 symbols are available, then there are 11 choices each are available for the two places and the total number of 10 which are 0 to 9, so, there are 9 choices each for the last four places,
Hence the final combination would be,
= 26 x 26 x 26 x 11 x 11 x 10 x 10 x 10
= 21,266,960,000
Hence the total password available are 21,266,960,000.

A plumber charges $25 for a service call plus $50 per hour of service. Write an equation in slope-intercept form for the cost, C, after h hours of service. What will be the total cost for 8 hours of work? 10 hours of work? On a graph
The equation in slope intercept form is C(h) = 50h+25 ,the total cost for 8 hours of work is $425 , and for 10 hours of work is $525.
In the question;
it is given that
the fixed charge of plumber = $25
charge for per hour of service = $50
the hours of service be "h"
and the total cost be "C"
according to the question
C(h) = 50h+25
the equation in the slope intercept form is C(h) = 50h+25
to find the total cost for 8 hours of work , put h=8
C(8) = 50(8) + 25
= 400+25
= 425
to find the total cost for 10 hours of work , put h=10
C(10) = 50(10) + 25
= 500+25
= 525
Therefore , total cost for 8 hours of work is $425 , and for 10 hours of work is $525 .
The given question is incomplete , the complete question is

The right angle, or 90°, is always one angle. The hypotenuse is the side with the 90° angle opposite.
If the side of DF = 7.7 cm then DE = 3.7 cm.
What is meant by right angle triangle?The right angle, or 90°, is always one angle. The hypotenuse is the side with the 90° angle opposite. The longest side is always the hypotenuse. The other two inner angles add up to 90 degrees.
A right triangle is a triangle in which one of the angles is at a right angle or two of the sides are perpendicular, or more formally, an orthogonal triangle, formerly known as a rectangled triangle. The foundation of trigonometry is the relationship between the sides and various angles of the right triangle.
Given: DF = 7.7 cm and ∠ E = 29°
Let the equation be
sin θ = P/h = DF / DE
substitute the values in the above equation, we get
⇒ sin 29° = 7.7 / DE
⇒ DE = 7.7 / 0.48 = 3.696 = 3.7 cm

Answer:

Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = 8, - 4) and (x₂, y₂ ) = (- 1, 5) ← 2 ordered pairs from the table
m = [tex]\frac{5-(-4)}{-1-8}[/tex] = [tex]\frac{5+4}{-9}[/tex] = [tex]\frac{9}{-9}[/tex] = - 1 , then
y = - x + c
to find c use any ordered pair from the table
using (2, 2 ) , then
2 = - 2 + c ⇒ c = 2 + 2 = 4
y = - x + 4 ← in slope- intercept form
with y- intercept c = 4

Write the equation of a line in slope intercept form that passes through (-15, 20) and is parallel to x - 5y = 5
First step is to write the equation in slope-intercept form
[tex]x - 5y = 5\\-5y = -x+5[/tex] To make simplification easier, multiply negative to both sides
[tex]5y = x-5\\[/tex] Now, you must divide 5 to both sides to isolate the variable
[tex]y = \frac{x}{5} - 1[/tex] To tell the slope more easily, turn [tex]\frac{x}{5}[/tex] into [tex]\frac{1}{5} x[/tex]
To rewrite the equation: [tex]y = \frac{1}{5} x - 1[/tex]
Now, you are able to see the slope(m) being [tex]\frac{1}{5}[/tex]
Next, you use the formula y=mx+b to solve for b (replace your newly found slope and points "x" and "y"

Checks: 32.96,121.03 and 24.70;cash:22 one dollar bills, 5 ten dollar bills, and 15.21 in coins; less $20 cash recieved
The balance of the checks and cash (receipts and payments) is -$245.90.
How is the balance determined?The balance is the difference between receipts of cash and payments of checks and cash.
Using addition and subtraction operations, the balance is determined as follows:
Check Payments:32.96
121.03
24.70
Total checks = $178.69
Cash Payments:22 one dollar bills = $22.00 (22 x $1)
5 ten dollar bills $50.00 (5 x $10)
15.21 in coins $15.21
Total cash payments = $87.21
Cash Receipts:$20 cash received
Total cash = $67.21
Balance = -$245.90 [$20 - ($87.21 + $178.69)]
Thus, the balance of the checks and cash totals -$245.90, showing that payments outstripped receipts.
