Answer:
4. j(11) = 8
I think it is linear
5. g(-3) = 18
No, it's a parabola since x is to the second power
6. f(-7) = 5
No, I think it's an absolute value function
7. h(0) = 13
I think it is linear, just the slope is 0
Step-by-step explanation:
Answer:
Look below.
Step-by-step explanation:
4.)
j(11) = 19 - 11
j(11) = 8
The equation is linear.
5.)
g(-3) = 2(-3)²
g(-3) = 2(9)
g(-3) = 18
The equation is not linear. It is quadratic.
6.)
f(-7) = |-7 - 1| - 3
f(-7)= |-8| - 3
f(-7) = 8 -3
f(-7) = 5
The equation is not linear. It is an absolute value function.
7.)
h(0) = -13
The equation is linear.

Which of the following parent functions has a domain and range of all real
numbers?
A. Cubic
B. Reciprocal
C. Quadratic
D. Absolute value
Parent functions has a domain and range of all real numbers is a Cubic function
Given :
We need to find the parent function that has a domain and range of all real
numbers.
Domain is the set of all x values and range is the set of y values.
For any cubic function there is no restriction for x
For each value of x there is a y value
So, domain and range of cubic function is set of all real numbers
For reciprocal function , there will be x in the denominator . So there will be some restriction for x.
For any quadratic function , domain is set of all real numbers. For quadratic we get U shaped graph . It means there is some restriction for y.
So range cannot be real numbers
For absolute value function , we get V shaped graph . so there is some restriction for y. Range cannot be all real numbers.
parent functions has a domain and range of all real numbers is a Cubic function

What is the value of x
Answer:
21
Step-by-step explanation:
The length of the other leg (x) is 12 cm.
We have,
To find the length of the other leg, we can use the Pythagorean theorem.
Using this theorem, we can set up the following equation:
x² + 5² = 13²
Simplifying the equation:
x² + 25 = 169
Subtracting 25 from both sides:
x² = 144
Taking the square root of both sides:
x = ±12
Since length cannot be negative in this context, the length of the other leg (x) is 12 cm.
Thus,
The length of the other leg (x) is 12 cm.

A ball is thrown into the air with an initial velocity of 22 meters per second.
The quadratic function ℎ() = −4.9
2 + 22 + 5.5 represents the height of
the ball above the ground, in meters, with respect to time , in seconds.
Part A: Determine ℎ(3) and explain what it represents.
Answer:
27.4 metres
Step-by-step explanation:
Um, your question is missing the x's. I'm going to assume, -4.9x^2+22x+5.5
= -4.9(3)^2+22(3)+5.5
= 27.4
At 3 seconds the ball is 27.4 metres above the ground.

2. Write a quadratic equation with roots (-2,0) and (4,0) that has a minimum value
of -36
Answer:
f(x) = 4*(x+2)*(x-4) factorized formula
f(x) = 4x^2 - 8x - 32 polynomical formula
Step-by-step explanation:
Lets assume the factorized formula of a quadratic function:
f(x) = a*(x-x1)^2 * (x-x2)^2
where "a" is a coefficient and x1, x2 are the roots of the function. Then replacing the given roots:
f(x) = a*(x+2)*(x-4)
because its told us that -36 is the minimum value of the function we can say that its concave, then this value is actually the component in the Y axis of the vertex. To find the component in the X axis of the vertex we have to make the adding between the roots and divide this value by 2, this last is because a quadratic function is a symetrical function. Lets call the component at the X axis of the vertex as Xv, then:
Xv=(x1+x2)/2
Xv=(-2+4)/2
Xv=1
Therefore now we have a point of the function and its P=(1,-36) this point is the vertex of the function too.
Now the last thing to do is to find the value of the coefficient "a". We can find it by replacing the point of the vertex obtained before.
-36 = a*(1+2)*(1-4)
-36 = a*(3)*(-3)
-36 = a*(-9)
4 = a
Finally the equation is:
f(x) = 4*(x+2)*(x-4)
if we expand this function we find the polynomical form of this function
f(x) = 4x^2 - 8x - 32

Find the mean, u, for the binomial distribution which has the stated values of n and p. Round answer to the nearest tenth. n=676; p=0.7
Answer:
[tex]\mu=473.2[/tex]
Step-by-step explanation:
Binomial Distribution
The binomial distribution is commonly used to model the number of successes in a sample of size n drawn with replacement from a population of size N.
The mean value of a binomial distribution is given by:
[tex]\mu=np[/tex]
Where b is the number of trials and p is the success probability for each trial.
We need to find the mean value with parameters n=676 and p=0.7, thus:
[tex]\mu=676\cdot 0.7[/tex]
[tex]\boxed{\mu=473.2}[/tex]

A bank manager wants to know the mean amount of mortgage paid per month by homeowners in an area.

Find a confidence interval for the mean amount of mortgage paid per month by all homeowners in this area. Round your answers to two decimal places. 1538.51 to 1627.49 dollars b. Suppose the confidence interval obtained in part a is too wide. Select all of the ways the width of this interval can be reduced.
Complete Question
The complete question is shown on the first uploaded image
Answer:
a
The 97% confidence interval is [tex]1528 < \mu < 1612 [/tex]
b
Option A and Option D are correct
Step-by-step explanation:
From the question we are told that
The sample size is n = 119
The sample mean is [tex]\$ 1570[/tex]
The population standard deviation is [tex]\sigma = \$ 211[/tex]
Generally given that the confidence level is 97% then the level of significance is mathematically represented as
[tex]\alpha = (100 - 97 )\%[/tex]
=> [tex]\alpha = 0.03[/tex]
From the normal distribution table the critical value of [tex]\frac{\alpha }{2}[/tex] is
[tex]Z_{\frac{\alpha }{2} } = 2.17[/tex]
Generally the margin of error is mathematically represented as
[tex]E = Z_{\frac{\alpha }{2} } * \frac{\sigma}{\sqrt{n} }[/tex]
[tex]E = 2.17* \frac{211}{\sqrt{ 119 } }[/tex]
=> [tex]E = 41.98 [/tex]
Generally the 97% confidence interval is mathematically represented as
[tex]\= x - E < \mu < \= x + E[/tex]
=> [tex]1570 - 41.98 < \mu < 1570 + 41.98 [/tex]
=> [tex]1528 < \mu < 1612 [/tex]
Generally looking at confidence interval we see that the width is dependent on the size of the margin of error.
Generally the margin error is directly proportional to the critical value of [tex]\frac{\alpha }{2}[/tex] which increases when the confidence level increases and vise versa
Also the margin error is inversely proportional to the square root of sample size
Hence to reduce the width of the confidence interval we need to lower the confidence level and increase the sample size
