Answer:
4) x = 3/2 , x = -1/2
Steps:
(2x-1)² - 4 = 0
4x²-4x+1 - 4 = 0
4x²-4x-3 = 0
x = (4±√((-4)²-4×4×(-3))/2×4
x = (4±√(16+48)/8
x = (4±√(64)/8
x = (4±8)/8
x = 12/8 , x = -4/8
x = 3/2 , x = -1/2

What is the equation for g(x)=
Answers
Answer:
g(x) = -(x + 3)^2 - 1
Step-by-step explanation:
g(x) has a peak, and goes down on both sides, it needs a negative sign. From the vertex, when x increases by 1, y decreases by 1, and when x increases by another 1, y decreases by 3. a = -1. The function is 3 units to the left and 1 unit down. That will make h = -3 and k = -1 to the function g(x) = a(x - h)^2 + k.

Determine the odds of drawing two aces if two cards are removed from
regular deck.
Answers
Answer:
The chance of drawing one of the four aces from a standard deck of 52 cards is 4/52; but the chance of drawing a second ace is only 3/51, because after we drew the first ace, there were only three aces among the remaining 51 cards. Thus, the chance of drawing an ace on each of two draws is 4/52 × 3/51, or 1/221

Which relation is a function?
Answers
Answer:
A.
Why:
Use the vertical line test. Essentially, if there are any points with the same x-coordinates but with different x-coordinates, it's not a function. If that doesn't make sense, if there is a line or point directly above or below another line or point, it's not a function. For example, B. has two lines underneath each other, with the same x-coordinates but different y. That means it's not a function.

So, the first triangle has a side length of 6 and x, and the bigger triangle has a side length of 10 and 11.
We divide 10 by 6 to find the scale factor, then divide 11 by that number.
10 ÷ 6 = [tex]\frac{5}{3}[/tex]
[tex]\frac{11}{\frac{5}{3} } = x\\\\\\11 * \frac{3}{5} = x\\\\\\\frac{33}{5}[/tex]= x
So, the answer is B. 6.6 because 33 divided by 5 is 6.6 (the value of x).

Caterpillar nitrogen assimilation and body mass. we explored the relationship between nitrogen assimilation and body mass (both on log scales) for data on a sample of caterpillars in Caterpillars. The Instar variable in the data codes different stages (1 to 5) of caterpillar development.
a. Fit a model to predict log nitrogen assimilation (LogNassim) using log body mass (LogMass). Report the value of for this model.
b. Fit a model to predict LogNassim using appropriate indicators for the categories of Instar. Report the value of for this model and compare it to the model based on LogMass.
c. Give an interpretation (in context) for the first two coefficients of the fitted model in (b).
d. Fit a model to predict LogNassim using LogMass and appropriate indicators for Instar. Report the value of and compare it to the earlier models.
e. Is the LogMass variable really needed in the model of part (d). Does the linear trend appear to be better when the caterpillars are in a free growth period? (Again, we are not ready to fit more complicated models, but we are looking at the plot for linear trend in the two groups.)
Answers
b B.Produce a similar plot using the log (base 10) transformed variables, LogNassim versus Log Mass. Again, comment on any patterns.
C. Would you prefer the plot in part (a) or part (b) to predict the nitrogen assimilation of caterpillars with a linear model? Fit a linear regression model for the plot you chose and write down the prediction equation.

Find the smallest digit d so that 437,d03 is divisible by 9.
Answers
9514 1404 393
Answer:
d = 1
Step-by-step explanation:
For the number to be divisible by 9, the sum of digits must be a multiple of 9. The sum of digits is ...
4 + 3 + 7 + d + 0 + 3 = 17 +d
The nearest multiple of 9 is 18, so we have ...
17 +d = 18
d = 18 -17 = 1
The value of d is 1.

Carpet King is trying to increase sales, and it has instituted a new promotion. All purchases can be
paid on the installment plan with no interest, as long as the total is paid in full within six months.
There is a $20 minimum monthly payment required. If the Schuster family buys carpeting for $2,134
and makes only the minimum payment for five months, how much will they have to pay in the sixth
month?
Answers
Answer:
The Schusters will have to pay $2,034 in the sixth month.
Step-by-step explanation:
Since Carpet King is trying to increase sales, and it has instituted a new promotion by which all purchases can be paid on the installment plan with no interest, as long as the total is paid in full within six months, and there is a $20 minimum monthly payment required, if the Schuster family buys carpeting for $2,134 and makes only the minimum payment for five months, to determine how much will they have to pay in the sixth month, the following calculation must be performed:
2134 - (5 x 20) = X
2134 - 100 = X
2034 = X
Therefore, the Schusters will have to pay $ 2,034 in the sixth month.
