The graph of [tex]f(x) = 2(3)^x[/tex] has an initial value of 2, and a rate is 3
The equation of the graph is given as:
[tex]f(x) = 2(3)^x[/tex]
The above equation is an exponential function.
An exponential function is represented as:
[tex]f(x) =ab^x[/tex]
Where:
a represents the initial valueb represents the ratex and f(x) are the variablesSo, the initial value of [tex]f(x) = 2(3)^x[/tex] is 2, and the rate is 3

janet earns $16 per week for doing chores around the house. write and solve an equation that determines how many weeks she needs to do chores to earn $12
Answer:
16x = 12 where x is the number of weeks she works, x = 3/4 of a week
Step-by-step explanation:
If Janet gets 16 dollars a week, then 16 times the number of weeks she works is the amount she makes. If x is the number of weeks she works, this would be 16x. Since she is trying to get $12 your equation would be 16x = 12.
Solving,
16x = 12
divide both sides of the equation by 16
x = 12/16 = 3/4

the track team is trying to reduce their time for a relay race. first they reduce by 2.1 minutes. then they are able to reduce the time by 1/10. if their final time is 3.96 minutes, what is their beginning time? show or explain your answer
Answer:
6.27 minutes
Step-by-step explanation:
x = beginning time
x - 2.1 - 0.21 = 3.96 *(1/10 of 2.1 is 0.21)
x - 2.31 = 3.96
x = 6.27
The figure shows two wires diverging from an intersection point at an angle of 20°. A vertical rod is located a distance x from the intersection point and is moving to the right at speed s. What is the rate of change of the area, dA/dt, formed by the two wires and the rod?
A. dA/dt = (1/2(s)tan20)x
B. dA/dt = (1/2tan20)x
C. dA/dt = ((s)tan20)x
D. dA/dt = (tan20)x
E. dA/dt = (2(s)tan20)x
Answer:
dA/dt = ( (S)tan20°)x
Option C) dA/dt = ((s)tan20)x is the correct Answer
Step-by-step explanation:
Given the data in the question and given figure in the image;
The second image mages a triangle ΔAOB
using SOH CAH TOA
such that;
tan = 0pp/adj
tan20° = AB / AO
tan20° = AB /x
AB = xtan20°
given; dx/dt = S
now, know that the area of a triangle is 1/2base×height
so Area of ΔAOB will be;
A = 1/2 × AO × AB
we substitute in AB = xtan20° and AO = x
A = 1/2 × x × xtan20°
A = 1/2 × x²tan20°
dA/dx = ( 1/2×2xtan20°)
dA/dx = ( xtan20°)
now
dA/dt = dA/dx × dx/dt
we substitute
dA/dt = ( xtan20°) × S
dA/dt = ( (S)tan20°)x
Therefore; Option C) dA/dt = ((s)tan20)x is the correct Answer

Step-by-step explanation:
Which graph represents (x,y)-pairs that make the equation y=0.5+5 true?
Choice B: (1,0), (3,4), (6,10)
Choice C: (2,6), (4,7), (6,8)
Answer:
Choice C
Step-by-step explanation:
Notice that the equation y = 0.5 x + 5
is a linear equation so the points that are solutions of it must reside on a line. Option A does not show aligned points, so it cannot be a possible answer.
Option B: we look into the given points and notice that just the first one (1, 0) is NOT a solution to the equation because:
y = 0.5 (1) + 5 = 5.5 and not "0"
Option C: This is the correct answer, since all those points satisfy the equation
Point (2, 6) --> y = 0.5 (2) + 5 = 1 + 5 = 6
Point (4, 7) --> y = 0.5 (4) + 5 = 2 + 5 = 7
Point (6, 8) --> y = 0.5 (6) + 5 = 3 + 5 = 8

Biologists studying horseshoe crabs want to estimate the percent of crabs in a certain area that are longer than 35 centimeters. The biologists will select a random sample of crabs to measure.
Which of the following is the most appropriate method to use for such an estimate?
A. A one-sample z-interval for a population proportion
B. A one-sample z-interval for a sample proportion
C. A two-sample z-interval for a population proportion
D. A two-sample z-interval for a difference between population proportions
E. A two-sample z-interval for a difference between sample proportions
Answer:
B. A one-sample z-interval for a sample proportion
Step-by-step explanation:
In this experiment we are only given the sample. Neither the population nor the two samples nor difference between two samples is given .
So we are left only with the option B which satisfies the required conditions.
We will estimate the sample proportion and then perform, the test.
The test are performed on the basis of the statistics given.
We have the sample and the proportion that it is not longer than 35 centimeters.
Therefore option B is the correct choice.
B. A one-sample z-interval for a sample proportion

A bakery ordered 90.4 pounds of flour. The next week, the bakery used 5.31 pounds of the flour baking cakes. How much flour does the bakery have left? sorry if it's hard
Answer:
The relationship shown for the flour and the cost is that of a direct variation because the graph is a straight line, noting that the increase of one variable causes also the increase to the value of the other. The point (1, 0.75) means that every pound of flour costs 0.75 dollar. From the graph given, the bakery will have to pay approximately $30 for 40 pounds of flour.

Answer:
i don not know this. but I think
Step-by-step explanation:
A police department commissioned a door-to-door survey of citizens on whether they commit minor law infractions, such as speeding or illegal parking. The interviewers told the interviewees that they would not be investigated or ticketed for any minor infractions they may have committed. An analysis suggested that there was bias in their responses.This would likely be an example of a (an):_________
a) Placebo effect
b) Interviewer-induced bias
c) Under-coverage bias
d) Voluntary response bias
e) Double-blind effect
Answer: Interviewer-induced bias
Step-by-step explanation:
The example given in the question illustrates the Interviewer-induced bias. This occurs when the situation created by the interviewer is such that the respondent will have to give the kind f answer that the interviewer wants to hear.
For example, in the question, we can deduce that the interviewers told the interviewees that they won't be investigated and the gave bias replies based on that.

What is area ?Area is the measure of a region's size on a surface. The area of a plane region or plane area refers to the area of a shape or planar lamina, while surface area refers to the area of an open surface or the boundary of a three-dimensional object.
here, we have,
we know that,
The area of a circle is given by
A = pi r^2
so, we get,
64 pi = pi r^2
Divide each side by pi
64 pi /pi= pi/pi r^2
64 = r^2
Take the square root of each side
sqrt(64) = sqrt(r^2)
8 = r
Hence, The solution is, The radius is 8 ft.
