Which of these statements is true for f(x)=(1/10)^x
A. The domain of f(x) is x > 0.
B. The graph contains (1)
C. It is always increasing.
D. The range of f(x) is y
Answers
Answer:it’s B trust me
Step-by-step explanation:
Statemen B is true about the given function.
What is the function?A relationship between a group of inputs and one output is referred to as a function. In plain English, a function is an association between inputs in which each input is connected to precisely one output. A domain, codomain, or range exists for every function. Typically, f(x), where x is the input, is used to represent a function.
A. The domain of f(x) is x > 0 is true for the function [tex]f(x) = (1/10)^x[/tex] because any positive real number can be raised to any real power, so the domain of this function is all real numbers greater than zero.
B. The statement "The graph contains (1)" is not clear. If it means whether the point (1, f(1)) lies on the graph, then we can find that [tex]f(1) = (1/10)^1 = 1/10[/tex], so the point (1, 1/10) lies on the graph. Therefore, the statement is true.
C. The function [tex]f(x) = (1/10)^x[/tex] is always decreasing because as x increases, [tex]f(x) = (1/10)^x[/tex] becomes smaller and smaller, approaching zero as x approaches infinity.
D. The range of f(x) is y < 1 because as x increases, [tex](1/10)^x[/tex] becomes smaller and smaller, approaching zero but never equaling one. So, the range of the function is all real numbers less than one, but not including one itself.

Which of the following numbers are less than -0.625
A) -8/5
B) -5/8
C)-0.5
*Choose all that apply*
Answers
Answer:
A) -8/5
Step-by-step explanation:
First, convert -8/5 and -5/8 to decimals
-8/5 = -1.6
-5/8 = -0.625
-0.5 is greater than -0.625 because it is closer to 0.
So, the only number less than -0.625 is -8/5, which is equivalent to -1.6
So, the correct answer is A) -8/5

And if the appointment is x miles away from man's house the equation is
Answers
Answer:
40 miles
Step-by-step explanation:
Since we are dealing in mph, change the minutes to hr
15 min: 15/60 = .25 hrs
3 min: 3/60 = .05 hrs
:
Let t = his normal drive time to work in hrs
then
40t = the distance to work
Write a distance equation; dist = speed * time
50(t-.25 + .05) = 40t
50(t - .20) = 40t
50t - 10 = 40t
50t - 40t = 10
10t = 10
t = 1 hr normal time to work
therefore
40(1) = 40 mi to work
:
:
Confirm this by finding the dist when he went 50 mph for 48 min (.8hrs)
50(1-.25+.05) = 50(.8) = 40 mi also

Courtney has $4.85 in nickels, quarters, and dimes. She has12 quarters and 7 nickels. How many more dimes than nickels does she have?
A. 8
B. 12
C. 15
D. 30
Answers
12 quarters= 3.00
7 nickles= .35
4.85-3.35= 1.50
1.50= 15 dimes
15-7= 8 more dimes
Answer:
8 dimes
Step-by-step explanation:
A quarter is $0.25, so 0.25 should be multiplied by the number of quarters she has:
0.25 * 12 = 3.00
A nickel is $0.05, so 0.05 should be multiplied by the number of nickels she has:
0.05 * 7 = 0.35
If we add this together, we get 3.35, and the rest of the money Courtney has is in dimes. First, find the amount of money left:
4.85 - 3.35 = 1.50
A dime is $0.10, so divide the amount of money left by 0.10 to find the number of dimes Courtney has:
1.50 ÷ 0.10 = 15
Subtract 15 by the number of nickels Courtney has to find how many more dimes she has than nickels:
15 - 7 = 8 dimes

The complete square of the given equation is (x - 7)² = 100 and the solution to the equation is x = 17 and -3.
What is a polynomial function?A polynomial function is a function that applies only integer dominions or only positive integer powers of a value in an equation such as the quadratic equation, cubic equation, etc. ax+b is a polynomial.
Rearranging the equation x² - 51 = 14
x²- 14x -51 = 0
x² - 14x + 49 - 49 - 51 = 0
(x - 7)² = 100
x - 7 = √100
x - 7 = ± 10
Taking RHS positive,
x - 7 = 10
x = 17
Taking RHS negative
x - 7 = -10
x = 7 - 10
x = -3
Thus, the complete square of the given equation is (x - 7)² = 100 and the solution to the equation is x = 17 and -3.
