What is the range of h
Answers
Answer:
The range of the function is the set of all possible outputs, that is, the set of all values obtained by applying the function to elements of the domain. So the set of all values which can be obtained by applying h(x) to an element of its domain is {−4,0,5,60} , and thus that is the range of h(x)

3. Tarzan went to the plant nursery and bought a tree that was initially 90 feet tall for his monkey friends to climb on.
After planting the tree, Tarzan made a table to record the height, h, of the tree, t years after it was planted. “Zero” is the time when he planted the tree.
t 0 1 2 3 4
h 90 105 120 135 150

(b) Find the remainder when f (x)=3x^3 −11x−48 is divided by x−1 .
(c) Let f (x)= x3 , g(x)= x+5. Find (f •g)(x)
(d) Find the derivative of y = 3+ x^2+ x^3y^3.
Answers
Answer:
a) A-B = { 1 , 3, 5 }
b) The remainder is 50
c) f + g)(x) = x⁴+ 5x³
d) [tex]\frac{dy}{dx} = \frac{2x- y^3(3x^2)) }{ 1- x^3 3y^2}[/tex]
Step-by-step explanation:
Step(I):-
1) a)
Let A = { 1, 3, 5, 7 } and B = { 7 , 14 , 21 }
A - B = {1,3,5,7} - { 7,14,21}
A - B = { 1 , 3, 5}
b)
Given f (x)=3x³−11x−48
x-1 ) 3 x³ - 11x -48 (- 3x²-3x -2

50
The remainder is 50
c) Given f(x) = x³ and g(x) = x + 5

Equation: y = -1/3x + 5
The slope intercep equation of the following points (0,5) (3,4) will be y = (-1/3)x + 5.
What is the slope-intercept equation?
A slope-intercept equation is the equation of the two variables x and y in which the form of the equation should be in such a way that it should contain the slope of the given equation.
For example, in the equation, y = mx + c here m will be the slope of the equation and this is the slope-intercept equation.
Another example is y = 3x + 7 here 3 will be the slope of that equation.
Slope m = difference in y coordinate/ difference in x coordinate.
Let's suppose our equation is y =mx + c
now m = (4 - 5)/(3 - 0)
m = -1/3 now for c put both point in the equation we get as 5.
So y = (-1/3)x + 5 will be correct slope intercept form.

Answers
Answer:
mean is 82, Median is 84, mode is 81
Step-by-step explanation:
The mean of the given data set is 82, median is 84 and mode is 81.
The given data set is 81, 87 93, 89, 61, 81.
What is the median?The median is the value that's exactly in the middle of a dataset when it is ordered.
Now, the ordered pair is 61, 81, 81, 87, 89, 93.
Median = (81+87)/2
=168/2
=84
Mean = Sum of all the observations/Number of observations
= (61 + 81 + 81 + 87 + 89 + 93)/6
= 492/6
= 82
Mode = The mode is the value that appears most frequently in a data set.
Here, 81 is the most frequently in the given data set.
Therefore, the mean of the given data set is 82, median is 84 and mode is 81.

720
Answers
======================================================
Work Shown:
f(x) = 3^x
a = 2 = lower value of the interval
b = 6 = upper value of the interval
c = average rate of change of f(x) from a to b
c = ( f(b) - f(a) )/(b - a) ..... note how this mimics the slope formula
c = ( f(6) - f(2) )/(6 - 2)
c = ( 3^6 - 3^2 )/4
c = ( 729 - 9 )/4
c = 720/4
c = 180
The average rate of change from x = 2 to x = 6 for f(x) = 3^x is 180

A U.S. government survey in 2007 said that the proportion of young Americans that earn a high school diploma is 0.87. a)Suppose you took a simple random sample of 100 young Americans. We know because of sampling variability that the sample proportion of those who earned a high school diploma would vary each time you took a sample. Assuming the value above can be taken as the population proportion (i.e. as a parameter), what model can be used to describe how these sample proportions would vary
Answers
Answer:
normal distribution can be used to model the sample proportions
Step-by-step explanation:
N ( sample size ) = 100
probability of earning high school diploma (p) = 0.87
probability of not earning high school diploma ( q ) = 0.13
hence ;
∈( P ) = p = 0.87
Var ( p ) = [tex]\frac{pq}{n}[/tex] = [tex]\frac{0.86 * 0.13 }{100}[/tex] = 0.001131
therefore ; p ~ N = ( 0.87 , 0.001131 )

I think x = 1 and y = 1/2. For the second: x = -1 4/13 or -1.307692, y = 4 1/4 or 4.25
Step-by-step explanation:
[1] 5x + 10y = 5
[2] -13x + 4y=17
Solve by Substitution :
// Solve equation [2] for the variable y
[2] 4y = 13x + 17
[2] y = 13x/4 + 17/4
// Plug this in for variable y in equation [1]
[1] 5x + 10•(13x/4+17/4) = 5
[1] 75x/2 = -75/2
[1] 75x = -75
// Solve equation [1] for the variable x
[1] 75x = - 75
[1] x = - 1
// By now we know this much :
x = -1
y = 13x/4+17/4
// Use the x value to solve for y
y = (13/4)(-1)+17/4 = 1
Solution :
