Jason has exactly four wooden toy blocks with digits on them. Two of the blocks have the digit 0, one of the blocks has the digit 1, and one of the blocks has the digit 2. How many distinct positive integers can he form using one or more of the blocks, without using each block more than once?
The number of positive integers is 24
How to determine the number of positive integers?The digits of the wooden toys are:
0, 0, 1, 2
Since each block cannot be used more than once, and there are four blocks in total;
The number of positive integers is;
Integers = 4!
Expand
Integers = 4 * 3 * 2 * 1
Evaluate
Integers = 24
Hence, the number of positive integers is 24

neither.
x y

The function relationship is a quadratic function
How to determine the function type?The function is given as:
x y
-5 17
-4 7
-3 1
-2 -1
-1 1
Remove the x values:
y: 17 7 1 -1 1
Calculate the difference between the consecutive y values
Difference: 10 6 2 -2
Because the first difference are not equal, it means that the function is not a linear function.
Calculate the difference between the above differences
Difference: 4 4 4
Because the second differences are equal, it means that the function is a quadratic function.
Hence, the function relationship is a quadratic function

25. A wheelchair access ramp has an angle of elevation of 16°. If the ramp
reaches to the top of a 22 inch high porch, how long is the ramp?
79.82 in.
76.81 in.
73.82 in.
81.5 in.
Answer:
C. 76.81
Step-by-step explanation:
We must use one of the trigonometric ratios to find the length, L, of the ramp. If we use 16 as the reference angle, the 22 in would be our opposite side and the ramp length is the adjacent.
Therefore, we must use tan, which is [tex]\frac{opposite}{adjacent}[/tex]:
[tex]tan (16)=\frac{22}{L} \\\\L*(tan(16)=22)\\\\L*tan(16)=22\\[/tex]
[tex]\frac{L*tan(16)}{tan(16)}=\frac{22}{tan(16} \\\\L=79.815=79.82 in.[/tex]
Ethan ran 3/4 miles. Megan ran 7/8 miles. How much further did Megan run? Answer in simplest form.
Answer:
2/16 or 0.625
Step-by-step explanation:
Find a common denominator for the two fractions. It will be 16. 3/4=12/16
7/8=14/16 or you can do it in decimal form. 3/4=.25 and 7/8= .875
.875-.25=.0.625
[tex]\large\boxed{\frac{1}{8}\ \text{miles}}[/tex]
We need to subtract Ethan's distance from Megan's. First, we need to have a common denominator in the fractions.
Multiply both the numerator and the denominator in [tex]\frac{3}{4}[/tex] by [tex]2[/tex] to get [tex]\frac{6}{8}[/tex], which is equivalent. Now, both numbers have a denominator of [tex]8[/tex] and can be subtracted.
Now, simply subtract the numerators, leaving the denominator alone.
[tex]\frac{7}{8}-\frac{6}{8}=\frac{7-6}{8}=\boxed{\frac{1}{8}}[/tex]

Which description best compares the graphs given by the equations:
x - 5y = -5 and -5x - 25y = 25
a. parallel
b. perpendicular
c. intersecting but not perpendicular
d. None of the above.
x - 5y = -5, -5x - 25y = 25
First, you'll need to get the x variable by itself.
x - 5y = -5
+5 +5
x = 0
So x is plotted on the 0.
For the second part of the first equation, you'll be looking for what the y variable represents.
x - 5y = -5
-x -x
-5y = -5
5 5
y = 1
So y is plotted on the 1 on the vertical line above the 0.
For the first part of the second equation, you'll do the same thing as in the first equation.
-5x - 25y = 25
+25 +25
-5x = 50
5 5
x = 10
So the x for this equation is plotted on 10 on the horizontal line.
For the second part of the second equation, you will do the same thing as in the first equation.
-5x - 25y = 25
+5 +5
-25y = 30
25 25
y = 1.2
So the y for the second half of the second question is plotted on 1.2 on the vertical line.
Perpendicular means the lines may or may not be of equal length and they will not be perfectly in line with each other.
Parallel means the lines may or may not be of equal length but will be perfectly in line with each other.
Intersecting means the lines may or may not be of equal length but will touch each other.

Let the equation of the function f will be
f(x) = ln x
If the function is multiplied with negative sign, then the function gets flipped about the x-axis.
And if we add 2 in the variable of the function, then the function gets shifted towards left.
Then the equation of the function g(x) will be
g(x) = - ln (x + 2)

Faruq has a identical markers, b identical pencils, and no other writing utensils in his locker. How many different collections of writing utensils could Faruq bring to class if he doesn't want to show up empty-handed?
Your answer should be an expression, which might involve the variables a and/or b.
The number of different collections of writing utensils could Faruq bring to class if he doesn't want to show up empty-handed is ab + a + b
How to calculate the different collection of writing utensils?Since Faruq has a identical markers, b identical pencils, and no other writing utensils in his locker and we require the number of collections or ways he could bring them to school without coming to school empty-handed, we use combination mathematics since order does not matter.
Now, Faruq can either come to school with one marker and one pencil or one pencil or one marker.
So, the combination for one marker and one pencil is n = a × b = ab
The combination for one marker is n' = a
The combination for one pencil is n" = b
So, the total combination is N = n + n' + n"
= ab + a + b
So, the number of different collections of writing utensils could Faruq bring to class if he doesn't want to show up empty-handed is ab + a + b
