A function is defined by fx) = 5(2-x). What is f(-1)?
Answer:
f ( x ) = 15
Step-by-step explanation:
Step 1:
f ( x ) = 5 ( 2 - x ) Function
Step 2:
f ( - 1 ) Given
Step 3:
f ( x ) = 5 ( 2 - ( - 1 ) ) Input x
Step 4:
f ( x ) = 5 ( 3 ) Combine Like Terms
Answer:
f ( x ) = 15
Hope This Helps :)
Answer:
15
Step-by-step explanation:
Since there is a -1 in place of the x, that means for every x value, x = the number in place of the x, so in this case every x would equal -1.
f(x) = 5(2-x)
f(-1) = 5(2+1)
f(-1) = 5(3)
f(-1) = 15

When a hypothesis is supported by many different experiments what is it considered
Answer:
Theory
Step-by-step explanation:
theory-is a hypothesis that has been proven and supported by many lot of experiments.
Answer:
It is called a theory
Step-by-step explanation:
For example, if a scientist has a hypothesis and it is proven true, then other scientists will also test it to be proved a theory. After changing different variables (sometimes), and yet it is still proven true, then it becomes a theory.

(NEED DONE QUICK) Two angles are supplementary. One of the angles measures 4(2x+9) and the other angle measures 2(4x-8) what is the value of x?
Answer:
[tex]x=10[/tex]
Step-by-step explanation:
Supplementary angles are angles equal to 180°.
Therefore:
[tex]4(2x+9)+2(4x-8)=180[/tex]
Now that we have our equation, let's distribute the [tex]4[/tex] and the [tex]2[/tex] into the parentheses they are next to:
[tex]8x+36+8x-16=180[/tex]
Combine like terms:
[tex]16x+20=180[/tex]
Subtract [tex]20[/tex] from both sides of the equation:
[tex]16x=160[/tex]
Divide by the coefficient of [tex]x[/tex], which is [tex]16[/tex]:
[tex]x=10[/tex]
~
Check your work by substituting [tex]10[/tex] into one of the equations above:
[tex]8(10)+36+8(10)-16=180[/tex]
[tex]80+36+80-16=180[/tex]
[tex]180=180[/tex]
It's correct!
What are the minimum and maximum values of t for which ſt + 31 < 2?
Answer:
maximum : [tex] ϵ -29 [/tex] a number infinitesimally larger than -29, or -28 if you prefer integers
minimum : [tex] -\infin [/tex]
negative infinity
Explanation:
if t + 31 < 2
than t + 31 - 31 < 2 - 31
t < -29
[tex] -\infin < t \:< - 29[/tex]
any number less than -29
ϵ just means infinitesimal small quantity denoted as [tex] \pm \frac{1}{\infin} [/tex]

find a formula for the amount of kool-aid in lake beta t hours after the crash.
The formula for the amount of Kool-Aid in Lake Beta t hours after the crash can be determined using the equation below: k(t) = 120(1 - 0.1)^(t/4)
When a shipment of Kool-Aid crashes near Lake Beta, the Kool-Aid powder gets dumped into the lake. The initial amount of Kool-Aid in the lake is 120 kg. The rate of decay for the Kool-Aid is 10% every 4 hours. We can determine the formula for the amount of Kool-Aid in Lake Beta t hours after the crash.
The formula for the amount of Kool-Aid in Lake Beta t hours after the crash can be determined using the equation below:
k(t) = 120(1 - 0.1)^(t/4)
In this equation, the initial amount of Kool-Aid in the lake is 120 kg. The rate of decay is 10%, which means that 10% of the Kool-Aid disappears every 4 hours.
This rate of decay is represented by the factor (1 - 0.1)^(t/4).
To determine the amount of Kool-Aid in the lake after t hours, we simply substitute the value of t into the equation.
For example, if we want to know the amount of Kool-Aid in the lake after 8 hours, we would substitute t = 8 into the equation;
k(8) = 120(1 - 0.1)^(8/4) = 84 kg
Therefore, after 8 hours, there would be 84 kg of Kool-Aid in Lake Beta.

find the ratio which are the points p(X,2) divides the line segment joining the point a(12,5) and b(4,-3) also find X plz give answer for this
Answer: ratio a:b = 3:5 p(X, 2) = p(9, 2)
Step-by-step explanation:
Plot points a = (12, 5) and b = (4, -3) and draw a line segment from a to b.
Notice that when y = 2, X = 9 so point p = (9, 2) see graph
The distance from a to p = 3√2
The distance from b to p = 5√2
So the ratio of a:b = 3√2:5√2 = 3:5 when simplified
To find the distance, use the distance formula OR pythagorean theorem.
Problem 1 Denote by 9 (t) is the position at time t of an object moving on a line. The function q need not be a position, q may be any differentiable function. The derivative, g, of a need not be a velocity, j is just the derivative of q. Assume that q is differentiable, so that its derivative, 9 = d', is the velocity, u: v (t) = (t) = ' (t) (1) Position and velocity are given, or measured, at three times, to, tı, and t2, with to 01 = v(tı) > 03 = v(t2) 20 (3) 059(to) = % <91 = q (ti) < 42 = 9 (t2) Assume also that the position increases as the velocity decreases on the interval of time [to, ta]. The problem is to establish a procedure to estimate a time t, between to and 1, when the position 4. = q (1.) is exactly halfway between qo and 4: 4. = 9(t.) = 40 +91 Assume that v is affine: for some constanta, v (t) = 10 + (t-to). (6) (1.1) Calculate a in terms of to, tı, to and v1. (5) (1.2) Find a formula for q (t) for every t in terms of t. to. 11, 90. 91.00, 01. (1.3) Then solve Equation (5) fort, in terms of to, +1.90:01. Vo, and 0. (1.4) Calculate the velocity when the position is halfway, v (t.)
1.1 ) velocity v1 is given as follows : 1/2 (4o + 42)
1.2) q(t) = qo + (t - to) (ti - to + 11 - 2to)/2 - (qo - q(to))
1.3) t = to + (1/2)(-49 - (ti - to)(ti - to + 11 - 2to) + 2(q(to) - qo))
1.4) v(t*) = t* - to + 7 - ti
(1.1)The constant a in terms of to, ti, to, and v1 is given as follows
.v(t) = 10 + (t - to)g(t)
= v(t) - v1g(t)
= 10 + (t - to) - v1
We know that
4. = 4(t.)
= 4o + 9 ıand 4. is exactly halfway between qo and
q4. 4. = q(t.)
= 4o + 1/2 (4 - 4o)
= 1/2 (4o + 42)
Therefore, we can equate these two expressions for
4.4o + 9ı
= 1/2 (4o + 42)8o - 4
= 9ı
Substituting v(t) = 10 + (t - to), we get
8o - 4 = v1 + (ti - to - 1)
v1 = 8o - 4 - (ti - to - 1)
Therefore, the value of the constant a in terms of to, ti, to, and v1 is given by
a = 8o - 4 - (ti - to - 1).
(1.2)We know that g(t) = v(t) - v1.
Since v(t) is given as v(t) = 10 + (t - to), we have
g(t) = v(t) - v1
= 10 + (t - to) - (8o - 4 - (ti - to - 1))
= t - ti + 11 - 2to
The position q(t) for every t is given by
q(t) = qo + ∫g(s) ds
where
qo = 4o + 91
= q(ti)
= q(to + ti - to)
= q(to) + ∫g(s) ds
From this equation, we get
∫g(s) ds = qo - q(to)
Therefore, q(t) = qo + (t - to) (ti - to + 11 - 2to)/2 - (qo - q(to))
(1.3)From the formula for q(t), we have
4o + 91 + (t - to) (ti - to + 11 - 2to)/2 - (qo - q(to))
= 1/2 (4o + 42)
Therefore, solving for t, we get
t = to + (1/2) ((4o + 42) - (4o + 91 + (ti - to)(ti - to + 11 - 2to)/2 + qo - q(to)))
= to + (1/2)(-49 - (ti - to)(ti - to + 11 - 2to) + 2(q(to) - qo))
(1.4)We have already found that
4. = 1/2 (4o + 42).
Substituting this in the formula for g(t) and evaluating at t = t*, we get
v(t*) = 10 + (t* - to) - v1
= 10 + (t* - to) - (8o - 4 - (ti - to - 1))
= t* - to + 7 - ti

The given information presents a network with a list of activities and their respective durations in weeks. The activities are interconnected, indicating their dependencies and the time required to complete each activity. The question asks for the earliest start time, earliest finish time, latest start time, and latest finish time for each activity in the network.
To determine the earliest start time, earliest finish time, latest start time, and latest finish time for each activity, we can utilize the concept of the Critical Path Method (CPM).
The CPM allows us to analyze the network and identify the critical path, which is the sequence of activities that determines the longest duration for completing the project.
To calculate the earliest start time (ES) and earliest finish time (EF) for each activity, we start by assigning ES = 0 for the first activity. Then, for each subsequent activity, ES is calculated as the maximum EF of its preceding activities. EF is then calculated by adding the activity duration to ES.
Next, we determine the latest finish time (LF) and latest start time (LS) for each activity. LF is initially set as the project duration, and LS is calculated by subtracting the activity duration from LF.
For each preceding activity, LF is determined as the minimum LS of its succeeding activities.
The critical path is identified by comparing the ES and LF values for each activity. Activities with ES equal to LS and EF equal to LF are part of the critical path.
The critical path represents the activities that, if delayed, would extend the project's overall duration.
By performing these calculations for the given network, we can determine the earliest start time, earliest finish time, latest start time, and latest finish time for each activity.
Additionally, the critical path can be identified based on the ES, EF, LS, and LF values.
