Use the function f (x) = 2x^2 – 5.
(Look at picture)
Answer:
C
Step-by-step explanation:
By the definition of an inverse function, if:
\(f(a)=b\text{ then } f^{-1}(b)=a\)
Therefore, the domain of the original function will be the range of the inverse function.
And the range of the original function will be the domain of the inverse function.
We have the original function:
\(f(x)=2x^2-5\)
With the domain:
\(-\infty<x<\infty\)
Since the domain of the original function is such, then the range of the inverse function is also the same as above.
So, the range of the inverse function is also:
\(-\infty< f^{-1}(x)< \infty\)
So, our answer is
C.
Notes:
A, B, and E would automatically be incorrect since we never use ”or equal to” when using the infinity symbol. This is because we can never “equal” infinity.

How many and what type of solutions does 5x2−2x+6 have?
1 rational solution
2 rational solutions
2 irrational solutions
2 nonreal solutions
Answer:
2 nonreal solutions
Step-by-step explanation:
given a quadratic equation in standard form
ax² + bx + c = 0 (a ≠ 0 )
then the nature of the roots are determined by the discriminant
b² - 4ac
• if b² - 4ac > 0 then 2 real and irrational solutions
• if b² - 4ac > 0 and a perfect square then 2 real and rational solutions
• if b² - 4ac = 0 then 2 real and equal solutions
• if b² - 4ac < 0 then no real solutions
5x² - 2x + 6 = 0 ← in standard form
with a = 5 , b = - 2 , c = 6
b² - 4ac
= (- 2)² - (4 × 5 × 6)
= 4 - 120
= - 116
since b² - 4ac < 0
then there are 2 nonreal solutions to the equation

Find the area of the shaded segment of the circle.
Answer:
The shaded segment = The arc area - The triangle
The arc area = pi x radius^2 x angle/360
= pi x 9^2 x (360-270)/360 = 63.61 (m2)
The triangle area = 9 x 9/2 = 41.5 (m2)
(because this is right triangle)
=> The shaded segment = 63.61 - 41.5 = 22.11 (m2)
Let f(x)=-5x-4 and g(x)=6x-7. Find f(x) + g(x)
Answer:
x - 11
Step-by-step explanation:
f(x) = -5x - 4
g(x) = 6x - 7
Find f(x) + g(x).
To find the sum of f(x) and g(x), we must substitute f(x) and g(x) with the given equations:
(-5x - 4) + (6x - 7)
To solve, we combine like terms.
-5x + 6x = x
-4 + (-7) = -11
Therefore, we end up with x - 11.

A bond yleided a real rate... A bond yieded a real rite of return of 3.87 percent for o time period when the infition rate was 2.75 percent. What was the actuai nominal rate of return?
8.28%
87.58%
7.77%
36%
6.77%
The actual nominal rate of return is approximately 6.68%. None of the provided answer options exactly match this value, but the closest option is 6.77%.
To calculate the actual nominal rate of return, we use the Fisher equation:
Nominal Rate = (1 + Real Rate) * (1 + Inflation Rate) - 1
Given:
Real Rate = 3.87% (0.0387 as a decimal)
Inflation Rate = 2.75% (0.0275 as a decimal)
Now, let's plug in the values:
Nominal Rate = (1 + 0.0387) * (1 + 0.0275) - 1
Nominal Rate = 1.0387 * 1.0275 - 1
Nominal Rate = 1.0668 - 1
Nominal Rate = 0.0668 or 6.68% (rounded to two decimal places)
So, the actual nominal rate of return is approximately 6.68%. None of the provided answer options exactly match this value, but the closest option is 6.77%.

The first statement is true, as the Tolivers are not eligible for a child credit regardless of the number of their children. However, the second statement is false, as the earned income credit is available to low-income taxpayers with dependent children.
The earned income credit helps to offset the burden of the federal payroll tax on low-income families and encourages individuals to seek employment rather than depend on welfare. Finally, the information about Mrs. Starling's employment does not provide enough information to determine any tax-related implications.
The statement regarding Mr. and Mrs. Toliver not being eligible for a child credit is true. Their Adjusted Gross Income (AGI) is $339,000, which is above the income threshold for eligibility for the child tax credit. The credit phases out for joint filers with AGI over $400,000, and they are not eligible due to their high income.
Regarding the Caseys, the earned income credit (EIC) is only available to low-income taxpayers with dependent children. The EIC helps offset the burden of federal payroll taxes on low-income families and encourages individuals to seek employment instead of relying on welfare. In the case of the Caseys, since Mrs. Casey is employed full-time as an attorney and Mr. Casey is an unpublished novelist with no income, they might not qualify for the EIC as they might not be considered low-income, depending on Mrs. Casey's salary.
Mrs. Starling worked for Abbot Inc. and earned $122,000 during her time there.

Gerard finds that 75 percent of the participants have dropped out of the study. What kind of problem has Gerard encountered in his study
Gerard has encountered a problem with attrition in his study. Attrition refers to the loss of participants or subjects who leave a study before it is completed. It can occur for various reasons, such as illness, death, disinterest, loss of contact with the participants, or other factors.
In Gerard's study, 75 percent of the participants have dropped out. This level of attrition is particularly high and could cause problems with the validity and reliability of the study's findings. When a significant number of participants drop out of a study, it can create biases in the data that remain, which could make it challenging to generalize the findings to the larger population or come to valid conclusions.
Therefore, Gerard must address this issue and determine why such a high percentage of participants have dropped out. To ensure the accuracy of the findings, he may need to replace the missing participants or consider the potential reasons for their departure when analyzing the data.

Define a relation R on Z as xRy if and only if x^2+y^2 is even. Prove R is an equivalence relation. Describe its equivalence classes.
A relation R on Z is an equivalence relation if and only if it is reflexive, symmetric, and transitive. Specifically, in this case, xRy if and only if x^2+y^2 is even.
Reflexive: for any x in Z, x^2+x^2 is even, thus xRx. So, R is reflexive.
Symmetric: for any x,y in Z, if xRy, then x^2+y^2 is even, which implies y^2+x^2 is even, thus yRx. So, R is symmetric.
Transitive: for any x,y,z in Z, if xRy and yRz, then x^2+y^2 and y^2+z^2 are both even, thus x^2+z^2 is even, thus xRz. So, R is transitive.
Therefore, R is an equivalence relation.
To describe the equivalence classes, we need to find all the integers that are related to a given integer x under the relation R.
Let [x] denote the equivalence class of x.
For any integer x, we can observe that xR0 if and only if x^2 is even, which occurs when x is even.
Therefore, every even integer is related to 0 under R, and we have:[x] = {y in Z: xRy} = {x + 2k: k in Z}, for any even integer x.
Similarly, for any odd integer x, we can observe that xR1 if and only if x^2 is odd, which occurs when x is odd. Therefore, every odd integer is related to 1 under R, and we have:[x] = {y in Z: xRy} = {x + 2k: k in Z}, for any odd integer x.
In summary, the equivalence classes of R are of the form {x + 2k: k in Z}, where x is an integer and the parity of x determines whether the class contains all even or odd integers.

In a bag there are 5 yellow marbles, 7 green marbles, 2 white marbles, and 6 blue marbles. IfT take 3 marbles without replacing them what is the probability of getting 2 white and a blue marble?
Answer:
1/190
Step-by-step explanation:
To calculate the probability of drawing 2 white marbles and 1 blue marble without replacement, we need to consider the total number of ways to choose 3 marbles out of the total number of marbles in the bag.
The total number of marbles in the bag is 5 + 7 + 2 + 6 = 20.
First, let's calculate the number of ways to choose 2 white marbles out of the 2 available:
Number of ways to choose 2 white marbles = (2 choose 2) = 1
Next, we need to calculate the number of ways to choose 1 blue marble out of the 6 available:
Number of ways to choose 1 blue marble = (6 choose 1) = 6
Now, we can calculate the total number of ways to choose 3 marbles out of the 20 marbles in the bag:
Total number of ways to choose 3 marbles = (20 choose 3) = 1140
Finally, we can calculate the probability by dividing the number of favorable outcomes (2 white marbles and 1 blue marble) by the total number of possible outcomes:
Probability = (Number of favorable outcomes) / (Total number of possible outcomes)
= (1 * 6) / 1140
= 6 / 1140
= 1 / 190
