G(x)=4x-7
Find g(-9)
G(x)=x^2-4x+11
Find g(-7)
Answer:
1) -43 2)-10
Step-by-step explanation:
so for the first one you would enter -9 into all of the x's
g(x)=4x-7
g(-9)=4(-9)-7 ( you would get -36, then you would minus y. so the answer is -43!)
g(-9)=-43
second one would be the same thing
g(x)=x^2-4x+11
g(-4)=-7^2-4(-7)+11
g(-4)=-10

In ΔGHI, h = 13 inches, i = 77 inches and ∠G=170°. Find the length of g, to the nearest inch.
Show your work plz and thank you :)
Ans
Step-by-step explanation:
254.16inches
Step-by-step explanation:
Using sine rule
g/sin25=510/sin122
Sin25=0.4226
Sin122=0.8480
g/0.4226=510/0.8480
Cross multiply
0.8480g=0.4226 x 510
0.8480g=215.526
Divide both sides by 0.8480
g=215.526/0.8480
g=254.16
The length of g is 70 inches.
What is Trigonometry?Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.
Given,
ΔGHI, h = 13 inches, i = 77 inches and ∠G=170°.
We need to find the length of G
Cosine rule: (for all triangles)
c²=a²+b²-2abcos(C)
=13²+77²-2.13.77.cos(175)
=169+5929-2002cos(175)
=6098-2002(0.598)
=6098-1197.2
c²=4901
Take square root on both sides
c=70.01
G=70.01
Hence, the length of g is 70 inches.

Angle DFG and Angle JKL are complementary angles. mAngle DFG= x+8.0 and mAngle JKL= x- 5.8 Find mAngle JKL
Answer:
m<JKL = 38.1
Step-by-step explanation:
We are given 2 angles, <DFG and <JKL, which are complementary angles, also that m<DFG = x+8.0 and m<JKL = x-5.8
Complementary angles are angles that add up to 90.
This means that m<DFG plus m<JKL is equal to 90.
As an equation, that would be:
m<DFG + m<JKL = 90
We can substitute m<DFG and m<JKL with their measures.
x + 8.0 + x - 5.8 = 90
Combine the x's.
2x + 8.0 - 5.8 = 90
Subtract 5.8 from 8.0.
2x + 2.2 = 90
Subtract 2.2 from both sides
2x = 87.8
Divide both sides by 2.
x = 43.9
We found the value of x, but we aren't done yet. The question wants us to find the measure of <JKL.
Remember that m<JKL=x-5.8
So, replace 43.9 as x and subtract 5.8 from it.
m<JKL = x-5.8 = 43.9 - 5.8 = 38.1
li y, ansari a (2014) a bayesian semiparametric approach for endogeneity and heterogeneity in choice models
Marketing variables that are included in consumer discrete choice models are often endogenous. Extant treatments using likelihood-based estimators impose parametric distributional assumptions, such as normality, on the source of endogeneity. These assumptions are restrictive because mis specified distributions have an impact on parameter estimates and associated elasticities. The normality assumption for endogeneity can be inconsistent with some marginal cost specifications given a price-setting process, although they are consistent with other specifications. In this paper, we propose a heterogeneous Bayesian semiparametric approach for modeling choice endogeneity that offers a flexible and robust alternative to parametric methods. Specifically, we construct centered Dirichlet process mixtures (CDPM) to allow uncertainty over the distribution of endogeneity errors. In a similar vein, we also model consumer preference heterogeneity nonparametrically via a CDPM. Results on simulated data show that incorrect distributional assumptions can lead to poor recovery of model parameters and price elasticities, whereas the proposed semiparametric model is able to robustly recover the true parameters in an efficient fashion. In addition, the CDPM offers the benefits of automatically inferring the number of mixture components that are appropriate for a given data set and is able to reconstruct the shape of the underlying distributions for endogeneity and heterogeneity errors. We apply our approach to two scanner panel data sets. Model comparison statistics indicate the superiority of the semiparametric specification and the results show that parameter and elasticity estimates are sensitive to the choice of distributional forms. The CDPM specification yields evidence of multimodality, skewness, and outlying observations in these real data sets.

A tank of diesel fuel contains 210 gallons. Every week, 5 gallons is used. A tank of gasoline contains 430 gallons. Every week, 16 gallons is used. After how many weeks will they have the same amount of fuel? How much fuel will each tank hold on that day?
Answer:
After 20 weeks both tanks have the same amount of fuel.
Diesel tank= 110 gallons
Gasoline tank= 110 gallons
Step-by-step explanation:
Giving the following information:
Diesel tank:
Total capacity= 210 gallons
Unitary daily use= 5 gallons
Gasoline tank:
Total capacity= 430 gallons
Unitary daily use= 16 gallons
First, we structure the total fuel loss formula for each tank:
Diesel tank= 210 - 5*x
Gasoline tank= 430 - 16*x
x= number of weeks
Now, we equal both formulas and isolate x:
210 - 5x = 430 - 16x
11x = 220
x= 20
After 20 weeks both tanks have the same amount of fuel.
Prove:
Diesel tank= 210 - 5*20= 110 gallons
Gasoline tank= 430 - 16*20= 110 gallons

Write the equation of the line through (2,4) with a slope of 2/3 in Point Slope Form
Answer:
y - 4 = 2/3(x - 2)
Step-by-step explanation:
The format for point-slope form is: y - y₁ = m(x - x₁)
where m is the slope, x₁ is the x-coordinate and y₁ is the y-coordinate.
In (2,4), 2 is the x-coordinate and 4 is the y-coordinate.
The slope is 2/3.
When you plug in the values, you get:
y - 4 = 2/3(x - 2)

PLEASE HELP!! I don't understand rate of change so please include a bit of an explaination.
Use the table to find the rate of change
Answer:
the rate of change is 4.
Step-by-step explanation:
It is 4 because to find the rate of change you need to see how many pieces of corn (y) there are for every serving (x). If you see if you plug in the number three in between 2 and 4 for the servings and you follow the pattern of the table you will get 12. Then you subtract 8 from 12 and you get 4.
so basically the rate of change is the difference in corn for every serving.

When a patient with hypertension takes a particular type of blood pressure medication, the effects on the systolic pressure, S(t), can be measured by the following piecewise defined function: S of t is equal to the piecewise function of 145 minus 6 times t if 0 is less than or equal to t is less than or equal to 5 and 115 if 5 is less than t is less than 9 and 52 plus 7 times t if 9 is less than or equal to t is less than or equal to 12 where t is the time, in hours, since taking the medication. Based on the graph of the piecewise function, if the patient takes the blood pressure medication at 7 a.m., in which interval will their systolic pressure be lowest?
a. 1 p.m. to 3 p.m.
b. 4 p.m. to 6 p.m.
c. 7 a.m. to 9 a.m.
d. 10 a.m. to 12 p.m.
HELP!!! PLEASE!!! ASAP!!! PRE-CALCULUS!!!
Finding the numeric values of the piecewise function, the blood pressure will be lowest in the following time:
a. 1 p.m. to 3 p.m.
How to find the numeric value of a function or of an expression?To find the numeric value of a function, we replace each instance of the variable in the function by the desired value.
In this problem, we have a piecewise function, that is, a function with different definitions based on the input, in which:
The input t is the time in hours after 7 am.The output S(t) is the blood pressure in t hours after 7 am.The numeric values are calculated next, looking at the definition for each value of t.
S(0) = 145 - 6(0) = 145.S(1) = 145 - 6(1) = 139....S(5) = 145 - 6(5) = 115.S(6) = S(7) = S(8) = 115.S(9) = 52 + 7(9) = 115.S(10) = 52 + 7(10) = 122.S(11) = 52 + 7(11) = 129.S(12) = 52 + 7(12) = 136.The lowest values are for t between 6 and 8, that is, between:
7 a. m. + 6 hours = 1 p.m.7 a. m. + 8 hours = 3 p.m.Hence option a is correct.

Write an equation of the line that passes through (3, 7) and is parallel to the line shown. (1, 4) (- 2, - 2)
Answer:
y=2x+1.
Step-by-step explanation:
You first need to find the slope of the line already graphed. -2 to 1 would be three units to the right, and -2 to 4 would be six units up. You would use the equation (y2-y1)/(x2-x1), where x1 and y1 would be the x and y values of the first coordinate of the graphed line, and x2 and y2 would be the second coordinate. This would be 6/3, which can be simplified to 2/1, which can be simplified to 2, which would mean the slope of the given line would be 2, as well as the parallel line. Now, you could use a pretty complicated equation to find the y-intercept of the line you need to graph, but I would recommend using the slope to find it. Since the given point is (3, 7), you would need to go to the left, meaning you would reverse the slope until you reach the y-axis, so you would use -2 as the slope. 3*-2=-6, and 7-6=1, so the y-intercept would be 1. The answer would be y=2x+1. Hope this helps.
