Question 4 How many integer numbers between 0 and 9999 are there that have exactly one digit 1 and exactly one digit 3
Answer:
768 numbers
Step-by-step explanation:
Given
[tex]Digits = \{0,1,2,3,4,5,6,7,8,9\}[/tex]
Required
Number of digits between 0 ad 9999 that have one 1 and one 3
There are a total of 4 digits that make up any of the numbers in 0 to 9999 with the given condition
This can be represented as WXYZ
Digit 1 can occupy any of the 4 positionsDigit 3 can occupy any of the 4 - 1 positionsThe remaining 8 digits will occupy the last 2 positions in the following ways:
The first of the 8 digits can be selected from any of [tex]\{0,2,4,5,6,7,8,9\}[/tex] i.e. 8 waysThe second can be selected from any of [tex]\{0,2,4,5,6,7,8,9\}[/tex] i.e. 8 waysSo, the total number of selection is:
[tex]Total = 4 * (4 - 1) * 8 * 8[/tex]
[tex]Total = 4 * 3 * 8 * 8[/tex]
[tex]Total = 768[/tex]
evaluate 13 - 0.75y + 8x when w =12 and x=1/2
Note: I am assuming you meant to write the value of y = 12 instead of w = 12.
So, I am assuming y = 12
Answer:
The value of 13 - 0.75y + 8x when we substitute y = 12 and x = 1/2 will be: 8
Step-by-step explanation:
Given the expression
[tex]13\:-\:0.75y\:+\:8x[/tex]
Given
y = 12x = 1/2substituting y = 12 and x = 1/2 in the expresion
[tex]13\:-\:0.75y\:+\:8x=13\:-\:0.75\left(12\right)\:+\:8\left(\frac{1}{2}\right)[/tex]
[tex]=13-0.75\cdot \:12+8\cdot \frac{1}{2}[/tex]
[tex]=13-9+4[/tex]
[tex]=8[/tex]
Therefore, the value of 13 - 0.75y + 8x when we substitute y = 12 and x = 1/2 will be: 8
Perform the indicated operation. 13 – (-4) 1 -1 17 -17
Answer:
sorry about being late! 17, C
Step-by-step explanation:
It's 13+4 since there are two negatives.
Two negatives cancel out to a postive in math, so it becomes 13 + 4.
13+ 4
= 17

What is Coordinates?A pair of numbers which describe the exact position of a point on a cartesian plane by using the horizontal and vertical lines is called the coordinates.
We have to given that;
The inequality is,
⇒ y ≤ 2x - 4
Now, From the options;
Option 3;
Point = (3, 2)
Put x = 3, y = 2;
⇒ y ≤ 2x - 4
⇒ 2 ≤ 2 × 3 - 4
⇒ 2 ≤ 6 - 4
⇒ 2 ≤ 2
Thus, The point which is the solution of the inequality y ≤ 2x - 4 is,
⇒ (3, 2)

Which statement is true of the function f(x) = -3^sqrt x ? Select three options.
The function is always increasing.
The function has a domain of all real numbers.
The function has a range of {y|–infinity < y < infinity }.
The function is a reflection of y = .3^sqrt x
The function passes through the point (3, –27).
Do you mean [tex]f(x)=-3^{\sqrt x}[/tex], as in the negative of 3 to the power of √x ? Or [tex]f(x)=-\sqrt[3]{x}[/tex], as in the negative cube root of x ?
If you mean [tex]f(x)=-3^{\sqrt x}[/tex], then, going through each option:
• no: the square root component is defined only for x ≥ 0, for which we have √x ≥ 0 and hence f(x) < 0 for all x in the domain. √x is an increasing function, so the powers of 3 get successively larger, so f(x) would be always decreasing;
• no: as mentioned above, the domain would be all non-negative numbers;
• no: at minimum, x = 0 which gives f (0) = -3⁰ = -1, and because f(x) is decreasing over its entire domain, the range would be {y | y ≤ -1};
• no: again, a bit of ambiguity, but assuming you mean to say here [tex]y=3^{\sqrt x}[/tex], yes, f(x) would be a reflection of y across the x-axis;
• and finally, no: [tex]f(3)=-3^{\sqrt3}\approx-6.705[/tex]
so that only the fourth option would be true.
On the other hand, if you mean [tex]f(x)=-\sqrt[3]{x}[/tex], then:
• no: the function is always decreasing;
• yes: the domain is all real numbers;
• yes: the range is {y | -∞ < y < ∞};
• yes: f(x) is a reflection of y=∛x, also about the x-axis; and
• no: f (3) = -∛3 ≈ -1.442
I suspect you mean the second case, since it's a bit simpler to approach.

Hank has $8 in dimes and nickels. He has a total of 105 coins. How many nickels does he have?
Answer:
50 nickelsStep-by-step explanation:
Let the number of nickels be n and dimes be d.
Consider:
n = 5¢, d = 10¢, $8 = 800¢We have equations below:
d + n = 10510d + 5n = 800Multiply the first equation by 10 and subtract the second equation to eliminate d and solve for n:
10d + 10n - 10d - 5n = 1050 - 8005n = 250n = 50He has 50 nickels

Catron evaluates the expression (-9)(2 2/5 using the steps below
Answer:
The answer is "-21.6".
Step-by-step explanation:
In the given question, there is a mistype in the equation so, its correct equation can be defined as follows:
Given:
[tex]\to (-9) (2 \ and \ 2/5) = (-9)(2+ \frac{2}{5})[/tex]
[tex]= (-9 \times 2 )+ (-9\times \frac{2}{5})\\\\= (-18 )+ ( -\frac{18}{5})\\\\= -18 -\frac{18}{5}\\\\= \frac{-90-18}{5}\\\\= - \frac{108}{5}\\\\=- 21.6[/tex]
OR
[tex]\to (-9)(2+ \frac{2}{5})= (-9) (\frac{10+2}{5})[/tex]
[tex]= (-9) (\frac{12}{5})\\\\= (-9) (2.4)\\\\=-21.6[/tex]
