2raised to power m-3 = 1
Answer:
m = 3
Step-by-step explanation:
Given:
[tex]2^{m-3}[/tex] = 1
Take the logarithm of both sides (logarithm of 1 is 0):
m - 3 = 0
Add 3 to both sides:
m - 3 + 3 = 0 + 3
m = 3
Hence, m = 3.
Logarithm is the power to which a number must be raised in order to get some other number. For example:
The base ten logarithm of 100 is 2, because ten raised to the power of two is 100: log 100 = 2. Meaning [tex]10^{2}[/tex] = 100.Match the line described on the left with the slope of the line on the right.
x=-3 , 6x-3y=18 , the line through (7,5) and (8,5) , the line through (4,-2) and (1,7)
Undefined -3 , 0 , 2
The Slope of x = -3 is undefined; 6x-3y=18 is 2; (4,-2) and (1,7) is -3; and (7,5) and (8,5) is 0.
What is the Slope of a Line?Slope of a line (m) = rise/run = change in y / change in x
Note that the slope of vertical lines are always undefined.
Therefore, we have the following:
x = -3 represents the equation of a vertical line, therefore, the slope is undefined.
6x - 3y = 18 is rewritten as y = 2x - 6 in slope-intercept form. The slope is 2.
For (4,-2) and (1,7):
Slope (m) = (7 -(-2))/(1 - 4) = 9/-3 = -3
For (7,5) and (8,5):
Slope (m) = 5 - 5/8 - 7 = 0/1 = 0

Trey's company makes solid balls out of scrap metal for various industrial uses. For one project, he must make aluminum balls that have a radius of 7.5 in. If
aluminum costs $0.12 per in, how much will the aluminum cost to make one ball?
Use 3.14 for x, and do not round your answer.
Thus, Cost of making 1 solid aluminium ball is found as $211.95.
Explain about the spherical shape:Something spherical is similar to a sphere in three dimensions in that it is round, or somewhat round. Even though they are never exactly round, oranges and apples are both spherical. Since an asteroid is frequently spheroidal—nearly round but lumpy—it has an approximately spherical form.
radius of solid aluminium balls r = 7.5 in.
Cost of of aluminium = $0.12 per cu. in.
Volume of sphere = 4/3 * π * r³
Volume of sphere = 4/3 * 3.14 * 7.5³
Volume of sphere = 1766.25 cu. in.
Cost of making 1 solid aluminium ball = 0.12 * 1766.25
Cost of making 1 solid aluminium ball = $211.95.
Thus, Cost of making 1 solid aluminium ball is found as $211.95.

After substituting the values as x=3 and y=7, the value of the expression "2x²-y¹+3x⁰" is 14.
In mathematics, an expression is a combination of numbers, variables, and mathematical operations (such as addition, subtraction, multiplication, and division) that can be simplified or evaluated to a numerical value.
To evaluate the expression 2x²-y¹+3x⁰ for x=3 and y=7, we substitute the given values, which are x=3 and y=7 into the expression and simplify:
On substituting the values,
We get,
= 2x² - y¹ + 3x⁰
= 2(3)² - 7¹ + 3(1)
= 2(9) - 7 + 3
= 18 - 7 + 3
= 14

The equation that models the amount of water in the tank after x minutes is:
y = -3x + 9
How many liters are there after x minutes?We know that the tank contains 9 liters of water, and it loses water at a constant rate of 3 liters per minute.
Then we can model the amount of water y in the tank after x minutes with a linear equation where the y-intercept is 9 and the rate of change is -3 (the amount it loses per unit of x)

What is Algebraic expression ?
An algebraic expression is a combination of variables, constants, and mathematical operations such as addition, subtraction, multiplication, and division. It may contain one or more terms, with each term separated by a plus or minus sign. Algebraic expressions are used in algebra to represent mathematical relationships and formulas.
The tax incidence (the division of the burden of a tax between buyers and sellers) does not depend on which side of the market the tax is levied on, but rather on the relative elasticities of supply and demand. In this case, we don't have information about the elasticities of supply and demand, so we cannot determine the tax incidence. However, we can infer that the tax on consumers did reduce the quantity sold (from 30 million liters to 25 million liters), so it's unlikely that a tax on producers would have had a larger effect.
Therefore, False. The effect of the tax on the quantity sold would not have been larger if the tax had been levied on producers.

The point (3,b) lies on the circle with radius 8 and center (−2,−1). What are the possible values of b
The point (3,b) can lie on the circle with radius 8 and center (-2,-1) for values of b equal to -1 + √39 and -1 - √39.
We know that the circle with radius 8 and center (-2,-1) has the equation:
(x + 2)² + (y + 1)² = 8²
Substituting x = 3 and y = b, we get:
(3 + 2)² + (b + 1)² = 8²
Simplifying, we get:
25 + (b + 1)² = 64
(b + 1)² = 39
Taking the square root of both sides, we get:
b + 1 = ± √39
Therefore, the possible values of b are:

In the coordinate plane, the point X (-1, 0) is translated to the point X' (3, 1). Under the same translation, the points Y (2, 3) and Z (1, -2) are translated to Y' and Z', respectively. What are the coordinates of Y' and Z'?
The coordinates of Y' are (6, 4) and the coordinates of Z' are (5, -1).
To find the coordinates of Y' and Z', we need to apply the same translation that maps X to X'.
We know that the vector that connects X to X' is (3 - (-1), 1 - 0) = (4, 1).
So, to translate Y to Y', we add the vector (4, 1) to the coordinates of Y:
Y' = Y + (4, 1)
= (2, 3) + (4, 1)
= (6, 4)
Similarly, to translate Z to Z', we add the vector (4, 1) to the coordinates of Z:
Z' = Z + (4, 1)
= (1, -2) + (4, 1)
= (5, -1)
Therefore, the coordinates of Y' are (6, 4) and the coordinates of Z' are (5, -1).

You want the tangent and secant of the angle θ the line x-3y=0 makes with the negative x-axis.
Trig functionsThe relations between the angle and its trig functions are ...
Tan = Opposite/Adjacent
Sec = Hypotenuse/Adjacent
Unit circleWe have shown the angle of interest in a unit circle with the "adjacent" side equal to the radius of the circle (1). Then the values of interest are ...
tan(θ) = opposite side = 1/3 . . . . . . . equal to the slope of the line
sec(θ) = hypotenuse = √(1 +(1/3)²) = √(10/9) = (√10)/3
The tangent is 1/3; the secant is (√10)/3.

Additional comment
A third-quadrant angle measured from the +x axis has a negative secant. The tangent is positive there.
Since this angle is measured from the -x axis, it isn't clear whether it is supposed to be considered a 3rd-quadrant angle or not. For the given acute angle θ shown, the trig functions are both positive. YMMV

In a sample of 1000 adults, 150 said they are very confident in the nutritional information on restaurant menus. for us adults are selected at random without replacement.
Find the probability that none of the four adults are very confident in the nutritional information on the restaurant menus.
The probability that none of the four adults is very confident in the nutritional information on the restaurant menus is 0.208 or approximately 20.8%.
Ready to approach this issue by utilizing the hypergeometric conveyance, since we are examining without substitution from a limited populace of two sorts (those who are exceptionally sure and those who are not exceptionally sure).
Let X be the number of grown-ups in a sample of 4 who are not exceptionally sure about the wholesome data on eatery menus.
At that point, X takes after a hypergeometric dissemination with parameters N = 1000, n = 4, and K = 850 (since 850 grown-ups are not exceptionally certain).
The likelihood that none of the 4 grown-ups are exceptionally certain can be communicated as:
P(X = 4) = (K select 4) / (N select 4)
where (K select 4) speaks to the number of ways to select 4 grown-ups from the population of 850 who are not exceptionally sure,
and (N select 4) speaks to the entire number of ways to select 4 grown-ups from the populace of 1000.
Utilizing the equation for binomial coefficients, ready to disentangle this expression as:
P(X = 4) = [(850*849*848*847) / (4*3*2*1)] / [(1000*999*998*997) / (4*3*2*1)]

Solve for x, in terms of y: 23 x + 15 y = 2
MAKE BRAINLYST AND 100
To solve for x in terms of y in the equation 23x + 15y = 2, we can start by isolating the term with x on one side of the equation. We can do this by subtracting 15y from both sides of the equation to get 23x + 15y - 15y = 2 - 15y, which simplifies to 23x = 2 - 15y.
Next, we can solve for x by dividing both sides of the equation by 23 to get 23x/23 = (2 - 15y)/23, which simplifies to x = (2 - 15y)/23.
Therefore, the solution for x in terms of y is x = (2 - 15y)/23.
