Enter your answers In the boxes as whole numbers
You can add __ zeros to the end of the number 40 to get the product of __.
Answer:
You can add 6 zeros to the end of the number 40 to get the product of 40 x 10^5.
Step-by-step explanation:
You can add 6 zeros to the end of the number 40 to get the product of 40×10⁵.
What are Arithmetic operations?Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operation is called the arithmetic operator.
Operators which let do a basic mathematical calculation
+ Addition operation: Adds values on either side of the operator.
For example 12 + 2 = 14
- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.
for example 12 -2 = 10
* Multiplication operation: Multiplies values on either side of the operator
For example 12*2 = 24
We have powers of ten that are used to determine the product of 40×10⁵.
So, the product 40×10⁵ can be obtained by appending 6 zeros to the end of the integer 40.
Hence, You can add 6 zeros to the end of the number 40 to get the product of 40×10⁵.

Answer:
(d) ∛27 and 3³
Step-by-step explanation:
If f(x) and g(x) are inverse functions, then f(g(x)) = g(f(x)) = x. Here, it looks like we're to assume that the functions are of the form f(x) = root(x) or f(x) = x^power.
a) these expressions evaluate to 25 and -25, so are additive inverses. We don't believe that is the intention of the question.
b) f(x) = √x; g(x) = x². f(g(121)) = √(121²) ≠ √121
c) f(x) = -∛(x); g(x) = (-x)³. f(g(64)) = -∛((-64)³) ≠ -∛64
d) f(x) = ∛x; g(x) = x³. f(g(3)) = ∛(3³) = ∛27 . . . . . . these are inverse operations

A pendulum 50 cm long vibrates 2° 30' each side of its standard position. Find the length of the are through which it swings .
Step-by-step explanation:
The pendulum swings over an angle of 2×(2°30') or 5° so we need to convert this to radian measure first:
[tex]5° × \left(\dfrac{\pi}{180°}\right) = 0.0873\:\text{rad}[/tex]
so the arc length is given by
[tex]s = r\theta = (50\:\text{cm})(0.0873\:\text{rad}) = 4.36\:\text{cm}[/tex]

the distance between bill's house and his aunt's house is 485 miles about how many miles would bill drive if he made 4 round trips from his aunt's house
Answer: 3880 miles
Step-by-step explanation:
Distance between Bill's house and his Aunt house = 485 miles
Distance traveled in one round trip = two times the distance between the Bill's house and his Aunt house
Distance traveled in one round trip = 2 x 485 = 970 miles
So, the distance traveled in 4 round trip = 4 x 970 = 3880 miles.
Thus, the distance traveled by the bill in 4 round trips is 3880 miles.

Answer:
Here both line are perpendicular because as product of slope of both lines is -1
Answer:
lines are perpendicular
Step-by-step explanation:
If 2 lines are perpendicular then the product of their slopes = - 1
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
(1)
y = [tex]\frac{3}{4}[/tex] x - 1 ← is in slope- intercept form
with slope m = [tex]\frac{3}{4}[/tex]
(2)
3y = - 4x + 6 ( divide each term by 3 )
y = - [tex]\frac{4}{3}[/tex] x + 2 ← in slope- intercept form
with slope m = - [tex]\frac{4}{3}[/tex]
Then
[tex]\frac{3}{4}[/tex] × - [tex]\frac{4}{3}[/tex] = - 1
Thus the 2 lines are perpendicular to each other

Answer:
a. correct
b. 3 for $315; 5 for $485
Step-by-step explanation:
You have correctly solved for x, the number of ski trips. As a practical matter, the formula is easier to use if you don't have to deal with mixed numbers or the odd fraction:
[tex]x=\dfrac{C-60}{85}[/tex]
Use that formula to find the number of ski trips for each of the given amounts.
x = (315 -60)/85 = 255/85 = 3 trips
x = (485 -60)/85 = 425/85 = 5 trips
