Answer:
See below.
Step-by-step explanation:
The domain is the set of numbers that can be substituted into the x-variable.
In a polynomial function of any degree, the domain is the set of real numbers.
If a function has x in the denominator or x in a square root, you must see which values of x make the function undefined, and exclude those values from the domain.
Solve for x in the following:
8x^2 + 6x = -5
Answer:
No solution or
(-3±[tex]2i\sqrt{31}[/tex])/8
Step-by-step explanation:
To get the solution, move everything to the left side of the equation:
8x²+6x+5 = 0
If you try to factor the equation or graph it, you will see that it will never equal 0.
If you need an imaginary solution you can plug it into the quadratic equation:
-6±[tex]\sqrt{36-160}[/tex] over 16
Simplify and you get
-6±[tex]i\sqrt{124}[/tex] over 16
-6±[tex]4i\sqrt{31}[/tex] over 16
Simplify the fraction and you can get
(-3±[tex]2i\sqrt{31}[/tex])/8

what is the answer to -4/3p -2/5
Answer:
Step-by-step explanation:
This expression consists of two fractions that have no common denominator but do have -2 as a common factor in the numerators.
Factoring out the -2, we get:
-2(2p/3 + 1/5)
If you want to go further, we can determine the LCD (which is 15) and then combine the fractions within parentheses:
-2(10p/15 + 3/15)
We could now factor out the 1/15 in each fraction:
-2

Step-by-step explanation:
To calculate the markup amount, use the formula: markup = gross profit/wholesale cost. If you know the wholesale cost and the markup percentage, then calculating the gross profit just involves multiplying those two numbers. To get to the final retail sticker price, add the gross profit to the original, wholesale cost.Feb 21, 2017
The image shows parallel lines cut by a transversal. The expressions represent unknown angle measurements. What is the value of x?
The value of x is 48°. Therefore, the answer is (A) 48.
We can solve for the value of x using the properties of parallel lines and transversals.
**Given:**
* Two parallel lines cut by a transversal.
* Two alternate exterior angles formed by the transversal on the parallel lines:
* **2x + 2°**
* **x + 50°**
**Solving for x:**
1. **Alternate Interior Angles:** We know that alternate interior angles formed by a transversal cutting parallel lines are congruent. Therefore:
- 2x + 2° = x + 50°
2. **Solve for x:**
- Combine like terms: x + 2° = 50°
- Subtract 2° from both sides: x = 48°
Therefore, the value of x is **48°.**
Therefore, the answer is (A) 48.
The probable question may be:
The image shows parallel lines cut by a transversal. The expressions represent unknown angle measurements. What is the value of x
A)48
B)51
C)54

Which is f(5) for the function -2x
Given:
Function:
[tex]f(x)=-2 x^{2}+2 x-3[/tex]
To find:
f(5)
Solution:
[tex]f(x)=-2 x^{2}+2 x-3[/tex]
Substitute x = 5 in the above function.
[tex]f(5)=-2 (5)^{2}+2 (5)-3[/tex]
[tex]=-2 (25)+10-3[/tex]
[tex]=-50+10-3[/tex]
[tex]=-40-3[/tex]
[tex]=-43[/tex]
Therefore, f(5) = -43.
Write 4.135 as a fraction
The fraction is 4135/1000.
To write the decimal number 4.135 as a fraction, we first observe that the digits 135 are in the thousandths place. Therefore, we can express the decimal as the fraction 4135/1000. This is because the decimal has three decimal places, and each place value to the right of the decimal point represents a power of ten.
When there's an interest in scientific notation, converting fractions into scientific notation may also be required. As an example, a tiny fraction like 0.0000045 would be written in scientific notation as 4.5 * 10^{-6}.
However, the question asks for a simple fraction, not scientific notation. Therefore, 4.135 as a fraction is simply 4135/1000.
The number 4.135 can be written as a fraction in the form of [tex]\frac{4135}{1000}[/tex]. In scientific notation, it can be expressed as 4.135 x [tex]10^{-3}[/tex], as moving the decimal point 0 places leaves the number unchanged.
To write the number 4.135 as a fraction, you first need to recognize that it is the same as 4135 divided by 1000 since there are three digits after the decimal point. Therefore, the fraction form of 4.135 is [tex]\frac{4135}{1000}[/tex]. This fraction can be simplified if desired by dividing both the numerator and the denominator by the greatest common divisor.
In scientific notation, the number 4.135 can be expressed as 4.135 x [tex]10^{-3}[/tex], because the power of 10 that keeps the number in its original form here is 0. Remember that scientific notation is written as a product of a number between 1 and 10 and a power of 10, where the power indicates how many places the decimal point is moved to the right (for positive powers) or to the left (for negative powers). Because the number is more than 1 but less than 10, we can keep it as is with a power of 10 that is 0.

The table shows input and output values for a cubic function. What is an approximate zero of the function?
Use the drop-down menus to complete the statements. A zero can be found between input values of blank because blank. One zero of the function is approximately blank.
The first blank or tab is -2 and -1, -1 and 0, 0 and 1, or 1 and 2
The second blank or tab is "the input values contain zeros", "the difference of these values is closest to zero" or "zero falls between the values f(x) for these inputs"
The third blank or tab is -0.9, -0.25, 0.25, or 0.9
What answers are they?
Answer:
Answer: first one is -1 and 0
Second one is: zero falls between the values of f(x) for these inputs
Third one is: -0.9
Step-by-step explanation:
A zero can be found between the input values of -1 and 0 because zero falls between the values f(x) for these inputs.
What is Function?A function is a relation from a set A to a set B where the elements in set A only maps to one and only one image in set B. No elements in set A has more than one image in set B.
Cubic functions are functions of the form,
f(x) = ax³ + bx² + cx + d = 0
We have input values and output values for those input values for the cubic function.
A zero of the function is the value of the input when output value equals zero.
When x = -1, f(x) = -0.5
When x = 0, f(x) = 2.5
The value of f(x) = 0 between these input values.
One zero of the function is approximately -0.9, which is more approximate.
Hence the zero of the function lies between -1 and 0.

Prove that the angle pqr is a right angle
Pls show full working out ty
Answer:
A missing bit of information is that ABCD must be a rectangle.
First, let's gather some facts:
(1) Angles in a triangle add up to 180.
(2) RQC and PBQ are the same triangles since it is given that their sides are equal.
(3) Also ∠PBQ = ∠QCR are 90° since they are in fact the corners of the rectangle.
(4) ∠PQB, ∠PQR and∠RQC are on the same line, so their sum must be 180°
Putting it all together, we can say for both triangles using (1):
∠RQC + ∠QRC + ∠QCR = 180 and ∠QCR=90 => ∠RQC = 90-∠QRC
∠PBQ + ∠BQP + ∠PQB = 180
Furthermore, since both triangles are equal (2):
∠QRC = ∠PQB
So, ∠RQC = 90 - ∠PQB
Finally, using (4) we can say:
∠PQB + ∠PQR + 90 - ∠PQB = 180.
Simplify that and you get:
∠PQR + 90 = 180
∠PQR = 90

evaluate the limit, or state that the limit does not exist. 9n - 3n / 2n
a.9
b. 3
c. limit does not exist
d. 0
Answer:
3
Step-by-step explanation:
Evaluating the limit of the function 9n - 3n / 2n.
First we factor out n from the numerator of the function to have
F(n) = n(9-3)/2n
Cancelling the variable n at the numerator with the one at the denominator we have:
Iim f(n) = 9-3/2
Iim f(n) = 6/2
Lim f(n) = 3
This shows that the limit of the function given is 3 no matter what the variable x is tending to.
Answer: Option b) 3
Step-by-step explanation:
We want to take the limit of the equation: (9n - 3n)/2n
Let's do it:
[tex]\lim_{n \to \infty} \frac{9n - 3n}{2n} = \lim_{n \to \infty} \frac{n(9-3)}{2n} = \lim_{n \to \infty} \frac{6}{2} = 3[/tex]
Really does not matter where we are looking for the limit, because this is a constant equation, so we have that the correct option is b) 3

The sum of nine-tenths and g is two-thirds solve for g
Answer:
- 7/30
Step-by-step explanation:
9/10 + g = 2/3
So subtract 9/10 from both sides of the equation to get g = -7/30
Thank me later :D
To solve for g, the sum of nine-tenths and g is two-thirds. By multiplying every term by the least common denominator and simplifying, we find that g is equal to -7/30.
Explanation:To solve for g, we need to isolate g on one side of the equation. Given that the sum of nine-tenths and g is two-thirds, we can write it as an equation: 9/10 + g = 2/3. To eliminate the fraction, we can multiply every term by the least common denominator (LCD), which is 30. This gives us 27 + 30g = 20. Simplifying the equation gives us 30g = -7. Finally, we can solve for g by dividing both sides of the equation by 30, resulting in g = -7/30.
