Answer:
29, 61
Step-by-step explanation:
x = smaller
y = larger
y = 3x - 26
x + y = 90
x + 3x - 26 = 90
4x - 26 = 90
4x = 116
x = 29
x + y = 90
29 + y = 90
y = 90 - 29
y = 61
Answer:
smaller angle = 29°
larger angle = 61°
Step-by-step explanation:
Let x be the larger angle and y be the smaller angle
Larger angle is 26° less than 3 times the smaller angle
i. e x = 3y-26°
Since x and y are complementary angles, we can write,
x + y = 90°
or, (3y - 26°) + y = 90°
or, 4y = 90° + 26°
or, y = 116°/4
or, y = 29°
So,
x = 3 * 29° - 26° = 61°

Answer:
1. 4
2. rise = 2; run = 1; slope = 2
3. y = 2x + 4
Step-by-step explanation:
1. Look at the graph. On the y-axis, the line passes through 4. The line crosses the y-axis at 4, so 4 is the y-intercept, and b = 4 in the equation y = mx + b.
2. Choose any two points on the line. I choose the y-intercept, (0, 4) and point (-1, 2).
slope = rise/run
We need to go from point (-1, 2) to point (0, 4) by only moving vertically and horizontally. Start at (-1, 2). Go up 2 units. That is a ris of 2. Now go right 1 unit to arrive at point (0, 4). that is a run of 1.
slope = rise/run = 2
3. We have b = 4, and m = 2.
y = mx + b
y = 2x + 4
Insert terms to make a identity replace *
(*-0.2n)^2=*-1.2mn+0.04n^2
The unidentified term is 3m.
What is equation?An equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Given that, an equation (x-0.2n)² = x-1.2mn+0.04n²
We know that, (a-b)² = a²-2ab+b²
Comparing the given equation with the above identity, we get,
a = x, b = 0.2n and 2ab = 1.2mn
Therefore, 2x×0.2n = 1.2mn
x = 3m
Hence, the unidentified term is 3m

if w denotes weight, n denotes number of items, m denotes maximum capacity constraint, and x =0 or 1, what would be the valid bounding condition/conditions for the sum of the subset problem?
So the valid bounding conditions for the sum of the subset problem are:
0 <= x[i] <= 1 (for all i such that 1 <= i <= n)
∑(w[i] * x[i]) <= m (for all i such that 1 <= i <= n)
The valid bounding condition for the sum of the subset problem is:
0 <= x[i] <= 1 (for all i such that 1 <= i <= n)
This means that each item can either be included in the subset (x[i] = 1) or not included in the subset (x[i] = 0).
The sum of the weights of the items in the subset should not exceed the maximum capacity constraint, m. So the bounding condition for the weight of the subset is:
∑(w[i] * x[i]) <= m (for all i such that 1 <= i <= n)
This means that the sum of the weights of the items in the subset should be less than or equal to the maximum capacity constraint.
So the valid bounding conditions for the sum of the subset problem are:
0 <= x[i] <= 1 (for all i such that 1 <= i <= n)
∑(w[i] * x[i]) <= m (for all i such that 1 <= i <= n)

Simplify the expression 10^log5
Answer:
5
Step-by-step explanation:
The logarithm function, denoted as "log," is the inverse of the exponentiation function. This means that if we have the expression "log(x) = y," then "x" is the base "b" raised to the power "y." In other words, "x" is equal to "b^y."
Using this definition, we can simplify the expression "10^log5" as follows:
10^log5 = 10^y
Where "y" is the exponent to which the base "10" must be raised to produce the result "5."
To find the value of "y," we can use the property of logarithms that states "log(b^y) = y." Applying this property to our expression, we have:
log(10^y) = y
Since "10^y" is equal to "5," we can substitute "5" for "10^y" in the above equation:
log(5) = y
Solving for "y," we find that "y = log(5)."
Therefore, the expression "10^log5" can be simplified to:
10^log(5) = 10^(log(5)) = 5
So the simplified result is 5.
What is the true solution to 2 ln e superscript ln 5 x baseline = 2 ln 15?
x = 3 is the true solution to 2 ln e superscript ln 5 x baseline = 2 ln 15, using the concept of simplification.
What is simplification?Make something simpler by simplifying it. In mathematics, reducing an expression, fraction, or issue to a simpler form is referred to as simplification. With calculations and solutions, the problem is made simple.
In order to achieve consistency in efforts, costs, and time, procedures must be simplified. It gets rid of variation and variety that is superfluous, harmful, and unproductive. It is termed simplification to use and interpret the function in order to make it simpler or easier to grasp.
The equation can be simplified by using the fact,
ln(eˣ) = x
This gives,
2 ln(5x) = 2·ln(15)
Comparing arguments, we see that,
5x = 15
x = 3
Check if it is true or not:
2 ln(e^(ln(5·3))) = 2·ln(15)
2 ln(e^2.70805) = 2·2.70805
2 ln(15) = 5.41610
and,
2·2.70805 = 5.41610

What is inequality?An inequality is a mathematical statement that shows the relative size of two values.
What is linear inequality?A linear inequality is an inequality that involves a linear expression, which is an expression that involves variables and constants, but no exponents or other mathematical operations. Linear inequalities are used to represent relationships between variables that are linear in nature.
This inequality can be rewritten as follows:

tenth of a minute, how long will it be until there are 20 grams of the element remaining?
It will be 13min until there are 20 grams of the element remaining.
What is exponential decay?
The term "exponential decay" in mathematics refers to the process of a constant percentage rate reduction in an amount over time. It can be written as y=a(1-b)x, where x is the amount of time that has passed, and is the initial amount, b is the decay factor, and y is the final amount.
Here, we have
This is a compound decay problem, which goes by the formula:
F = P(1-r)ˣ
Where
F is the future amount (we want it to be 20)
P is the present amount (240 now)
r is the rate of decay per minute (17.4% = 17.4/100 = 0.174)
x is the time it takes (what we want to find)
Substitute all values in the formula and we get
20 = 240(1-0.174)ˣ
20 = 240(0.826)ˣ
0.0833 = 0.826ˣ
㏑0.0833 = ㏑0.826ˣ
㏑0.0833 = x ㏑0.826
x = ㏑0.0833/㏑0.826
x = 13
Hence, it will be 13min until there are 20 grams of the element remaining.
