A book with 53 pages numbered 1 to 53 has its pages renumbered in reverse, from 53 to 1. For how many pages do the new page number and old page number share the same units digit?
Answer:
Page number 27 is the one whose order has not changed
Step-by-step explanation:
Answer:
11
Step-by-step explanation:
Each page is assigned two numbers. We can generalize the numbers assigned to page x to be the pair x and 54-x for 1 ≤ x ≤ 53. That is, if x = 1, then we can see that page number one is assigned the numbers 1 and 54-1 = 53. It is fairly easy to see that the unit digits of x and 54-x will only be the same if x has a unit digit of 2 or a unit digit of 7. Thus, we simply must count how many such x there are between 1 and 54. Possibilities for x are 2, 7, 12, 17, 22, 27, 32, 37, 42, 47, and 52. Therefore, there are 11 such pages.

Answer:
A. Nonlinear function
Step-by-step explanation:
No vertical line intersects the graph in more than one place, so it is a function (not a "relation").
The graph is not a straight line, so is not a linear function. It is a nonlinear function.
Answer:
nonlinear function
Step-by-step explanation:
A linear function is a straight line, a nonlinear function is a curved line, and a relation is a relationship between two points on a graph, such as an equation.

Find the perimeter of this figure to
the nearest hundredth. Use 3.14 to
approximate a.
P = [?] ft
Answer:
P = 40.56 ft
Step-by-step explanation:
The figure is composed of a rectangle and half circle
The perimeter of the figure = the length of the borders round the figure
= W + 2L + ½(perimeter of full circle)
W = 8 ft
L = 10 ft
½(perimeter of circle) = ½(πd) = ½(3.14*8)
= 12.56 ft
Plug in the values
Perimeter of the figure = 8 + 2(10) + 12.56
= 8 + 20 + 12.56
= 40.56 ft

It is believed that students who begin studying for final exams a week before the test score differently than students who wait until the night before. Suppose you want to test specifically that students who study earlier have an average score that is less than the average score for students who wait to study. What are the hypotheses for this test if early studiers are group 1 and procrastinators are group 2
Answer:
H0 : μ1 = μ2
H0 : μ1 < μ2
Step-by-step explanation:
Given :
Early studiers, group 1, mean μ1
Late studiers, group 2 ; mean, μ2
To test the claim that students who study earlier have an average score that is less than the average score for students
The null hypothesis ; there is no difference in average score
H0 : μ1 = μ2
Alternative hypothesis is early studiers means is less than average score of late studiers
H0 : μ1 < μ2

Subtract 32 from the product of 48 and 15.
A. 32 – (48 × 15)
B. (48 – 15) × 32
C. (48 × 15) – 32
D. 32 × (48 – 15)
Please quick
Answer:C
Step-by-step explanation: you have to multiply first than subtract because it says subtract 32 FROM the product meaning multiplying comes first than subtract
What is the slope of the line with points (-3, 2) and (-3, -2)?
Answer:
-4
Step-by-step explanation:
(-3 , 2) = (x1 , y1)
(-3 , -2) = (x2 , y2)
slope (m) = y2 - y1/x2 - x1
=-2-2/-3-(-3)
=-4/-3+3
=-4/0
=-4
Answer:
No slope.
Step-by-step explanation:
We want to find the slope of the line with the points (-3, 2) and (-3, -2).
To find the slope of any line, we can use the slope formula:
[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]
We can let (-3, 2) be (x₁, y₁) and (-3, -2) be (x₂, y₂). Substitute:
[tex]\displaystyle m=\frac{(-2)-(2)}{(-3)-(-3)}[/tex]
Evaluate:
[tex]\displaystyle m=\frac{-2-2}{-3+3}=\frac{-4}{0}[/tex]
Anything divided by zero is undefined.
Therefore, the slope does not exist. The line has no slope.
If you plot the two points and graph the line, you can see that it is a vertical line. If you recall, vertical lines have no slopes.

3s(4+6)^2 is an example of
A. an algebraic equation
B. a numerical expression
c. a numerical equation
D. an algebraic expression
Answer:
the answer for this is D.
Step-by-step explanation:
it is a combination of letters operations and variables.But it is not equated (=) to something that is why it is not an algebraic equation.It is also not a numerical equation or numerical expression because it does not consist of only numbers.
3s(4+6)² is an example of an algebraic expression.
What is an algebraic expression?"An algebraic expression is an expression built up from integer constants, variables, and the algebraic operations."
The given expression is:
3s(4+6)²
The given expression is not an equation as it does not contain an equal sign. It is an expression.
Therefore, it is neither algebraic nor numerical equation.
Now, it contains a variable 's'.
Therefore, it is not a numerical expression.
Hence, the given expression is an algebraic expression.

Differentiate 4^xlnx
If you mean
[tex]\dfrac{\mathrm d}{\mathrm dx}\left[4^x\ln(x)\right][/tex]
then first write [tex]4^x=e^{\ln(4^x)}=e^{\ln(4)x}[/tex]. Then by the product rule,
[tex]\dfrac{\mathrm d}{\mathrm dx}\left[4^x\ln(x)\right] = \ln(4)e^{\ln(4)x}\ln(x) + \dfrac{e^{\ln(4)x}}x = \ln(4)4^x\ln(x)+\dfrac{4^x}x=\dfrac{4^x}x\left(\ln(4)x\ln(x)+1\right)[/tex]
If you instead mean
[tex]\dfrac{\mathrm d}{\mathrm dx}\left[4^{x\ln(x)}\right][/tex]
you can again rewrite [tex]4^{x\ln(x)} = e^{\ln\left(4^{x\ln(x)}\right)}=e^{x\ln(x)\ln(4)}[/tex]. Then by the chain and product rules,
[tex]\dfrac{\mathrm d}{\mathrm dx}\left[4^{x\ln(x)}\right] = e^{x\ln(x)\ln(4)}\ln(4)\left(\ln(x)+1\right) = 4^{x\ln(x)}\ln(4)(\ln(x)+1)[/tex]

Substitute for f(x) and g(x) and simplify.
(f -g)(x) = f(x) -g(x)
(f -g)(x) = (2x^2 +2) -(x^2 -1) = 2x^2 +2 -x^2 +1
(f -g)(x) = x^2 +3
