Which of the following statements is NOT true regarding simplifying
rational expressions?
When dividing one rational expression by another rational expression, you
can rewrite your expression as a multiplication problem.
When multiplying two rational expressions together, you must first have a
common denominator.
When adding two rational expressions together, you must first have a
common denominator,
When multifying two rational expressions together, the numerators get
multiplied together while the denominators get multiplied together.
Answer:
The only untrue statement is
- When multiplying two rational expressions together, you must first have a
common denominator.
Step-by-step explanation:
A rational expression has a rational numerator and a rational denominator.
To investigate each of these statement, we take two arbitrary rational expressions
Rational expression 1 = (a/b)
Rational expression 2 = (c/d)
Taking the statements one at a time
- When dividing one rational expression by another rational expression, you
can rewrite your expression as a multiplication problem.
(a/b) ÷ (c/d) = (a/b) × (d/c)
This statement is obviously true.
- When multiplying two rational expressions together, you must first have a
common denominator.
(a/b) × (c/d) = (ac/bd)
We do not need b = d to do this multiplication, hence, this statement is false.
- When adding two rational expressions together, you must first have a
common denominator,
(a/b) + (c/d)
We first take an LCM, so that we then have
(ad/bd) + (bc/bd)
= (ad + bc)/bd
This statement is true also.
- When multiplying two rational expressions together, the numerators get
multiplied together while the denominators get multiplied together.
(a/b) × (c/d) = (ac/bd)
This statement is true.
So, only the second statement is not true.

Write the product using exponents.
(-1\2). (1/2).(1/2).
The product (-1/2) \\cdot (1/2) \\cdot (1/2) simplifies to -1 \\cdot (1/2)^2, which equals -1/4 when written using exponents.
The product of these fractions, (-1/2) \\cdot (1/2) \\cdot (1/2), can be written using exponents. Since we are multiplying the same base, (1/2), we simply add the exponents. The fraction -1/2 can be thought of as (-1) \\cdot (1/2), so it won't affect the exponent but will contribute a negative sign to the product.
To use exponents, we count how many times the base (1/2) is used as a factor: twice. We can express this as (1/2)^2. Combining this with the negative sign from (-1/2), the final expression is -1 \\cdot (1/2)^2, which simplifies to -1/4 because (1/2)^2 = 1/4.

Which of the following measurements is shorter than 1 meter select all that apply
Measurements shorter than 1 meter are usually in centimeters and millimeters; for example, the length of a hand or the size of a small worm. Longer measurements such as the length of a street or the distance between towns are in meters or kilometers.
Explanation:In the metric system, the length measurements shorter than 1 meter include centimeters (cm) and millimeters (mm). To identify which measurements are shorter than 1 meter, we can consider the size or distance involved. Some options include:
The size of a small worm is definitely shorter than 1 meter and would be measured in centimeters or even millimeters.The height of a light switch is also less than 1 meter and can be measured in centimeters.The length of a hand is smaller than 1 meter and would be measured in centimeters.On the other hand, measurements that are likely to be equal to or longer than 1 meter might include:
The length of a street, which would be measured in meters or kilometers.The distance from one town to the next, which would be measured in kilometers.The depth of a pool, which could be measured in meters depending on the pool's depth.Understanding that 1 meter is roughly the distance from fingertip to fingertip when arms are stretched out to the sides can help visualize the scale when deciding on the appropriate unit for measuring length.

How many times bigger is the 45,776 than 45.776
Answer:
54
Step-by-step explanation:
45,776 is exactly 1,000 times bigger than 45.776, as you can move the decimal point in 45.776 three places to the right to match the value of 45,776.
To determine how many times bigger 45,776 is than 45.776, we simply divide the larger number by the smaller number:
First, write down the two numbers: 45,776 and 45.776.Convert 45.776 to the same form as 45,776 by multiplying by 1000 (to move the decimal point three places to the right).The calculation will look like this: 45,776 / (45.776 x 1000) = 45,776 / 45,776 = 1,000.45,776 is 1,000 times bigger than 45.776.

Explain how you can find the area of a polygon
Step-by-step explanation:
To find the area of a regular polygon, all you have to do is follow this simple formula: area = 1/2 x perimeter x apothem. Here is what it means: Perimeter = the sum of the lengths of all the sides. Apothem = a segment that joins the polygon's center to the midpoint of any side that is perpendicular to that side.Final answer:
The area of a polygon can be estimated using a grid to count squares, with specific formulae used for regular shapes. Irregular shapes can be broken down into simpler shapes, and the areas summed up, or approximated as areas under a curve using rectangles.
Explanation:
To find the area of a polygon, one approach can be to approximate the area using graph paper. You would place the polygon over a grid and count the number of squares that are completely covered by the polygon. Partial squares would be estimated. For polygons with straight sides like triangles, rectangles, and other regular shapes, you can use specific formulae. For example, the area of a triangle is found using the formula A = wh/2, where 'w' is the base width and 'h' is the height.
To find the area of irregular shapes, the shape can be broken down into a combination of known shapes, then the area for each known shape is calculated and summed up. For instance, if you're finding the area within a curve represented by a graph, you can approximate the area under the curve by summing up the areas of rectangles (or triangles) that fit under the curve.
DEF is a right triangle.

The graph of an exponential model in the form y = a ⋅ bx passes through the points (2, 50) and (3, 250). Which point is also on the graph?
A. (0, 5) B. (1, 10) C. (4, 450) D. (5, 650)
The correct answer is B: (1, 10).
To determine which point is also on the graph of the exponential model [tex]\(y = a \cdot b^x\)[/tex], we can use the given points (2, 50) and (3, 250) to set up a system of equations.
For the point (2, 50):
[tex]\[50 = a \cdot b^2\][/tex]
For the point (3, 250):
[tex]\[250 = a \cdot b^3\][/tex]
Dividing the second equation by the first, we get:
[tex]\[\frac{250}{50} = \frac{a \cdot b^3}{a \cdot b^2}\][/tex]
Simplifying:
[tex]\[5 = b\][/tex]
Now that we know [tex]\(b = 5\)[/tex], we can substitute this back into either of the original equations to solve for [tex]\(a\)[/tex]. Using the first equation:
[tex]\[50 = a \cdot 5^2\][/tex]
Solving for \(a\):
[tex]\[a = 50/25 = 2\][/tex]
So, the exponential model is [tex]\(y = 2 \cdot 5^x\)[/tex].
Now we can check which of the given points is on the graph:
- For point (0, 5): [tex]\(y = 2 \cdot 5^0 = 2 \cdot 1 = 2\)[/tex]
- For point (1, 10): [tex]\(y = 2 \cdot 5^1 = 2 \cdot 5 = 10\)[/tex]
- For point (4, 450): [tex]\(y = 2 \cdot 5^4 = 2 \cdot 625 = 1250\)[/tex]
- For point (5, 650): [tex]\(y = 2 \cdot 5^5 = 2 \cdot 3125 = 6250\)[/tex]
The only point that satisfies the exponential model is (1, 10). Therefore, the correct answer is B. (1, 10).

Over which interval is the graph of f(x) = –x2 + 3x + 8 increasing? (–∞, 1.5) (–∞, 10.25) (1.5, ∞) (10.25, ∞)
Answer:
(–∞, 1.5) or A on edge
Step-by-step explanation:
took the test
Over (∞, 1.5), the graph of f(x) = -x² + 3x + 8 is increasing.
A relation f from a set A (the domain of the function) to another set B (the co-domain of the function) is called a function in math. f = {(a,b)| for all a ∈ A, b ∈ B}
It is given that function is
f(x) = -x² + 3x + 8
We know that graph of f(x) is increasing if f’(x) > 0
-2x + 3 > 0
-2x > -3
x < 3/2 or 1.5
Thus, the graph is increasing over (∞, 1.5).

solve the following system y=-2 -4x+8y=0
Answer:
x = -4
y = -2
Step-by-step explanation:
All you need to do is plug in the number given for y into the equation:
-4x + 8y = 0
-4x + 8(-2) = 0
-4x - 16 = 0
Add 16 to both sides:
-4x - 16 = 0
+ 16 + 16
____________
-4x = 16
Finally, divide both sides by -4:
-4x = 16
x = -4
So now you have, x = -4 and y = -2
