The function h(t) = −16t2 + 24t models the height, in feet, of a kangaroo t seconds after it jumps. What is the maximum height o

ch4aika [34]

Step-by-step explanation:

The height of kangaroo after it jumps is represented by the function $h(t)=24t-16t^{2}$ , where $t$ is in seconds, height is in feet.

To find the maximum height that the kangaroo jumps, we need to maximise $h(t)$ .

The minimum/maximum value of a quadratic expression $ax^{2}+bx+c$ is given by $\dfrac{4ac-b^{2}}{4a}$ .

As the coeffecient of quadratic term is negative, the function has a maxima.

Maximum value = $\dfrac{4(-16)(0)-(24)^{2}}{4(-16)}=\dfrac{-576}{-64}=9$ .

∴ Maximum height = 9 ft

F(x)=x2 what is g(x)?

Oksi-84 [34.3K]

g(x) = (1/4)x^2 . correct option C) .

<u>Step-by-step explanation:</u>

Here we have , $f(x)=x^2$ and we need to find g(x) from the graph . Let's find out:

We have , $f(x)=x^2$ . From the graph we can see that g(x) is passing through point (2,1 ) . Let's substitute this point in all of the four options !

A . g(x) = (1/4x)^2

Putting (2,1) in equation g(x) = (x/4)^2 , we get :

⇒ $g(2)= (\frac{2}{4} )^2$

⇒ $1\neq \frac{1}{4}$

Hence , wrong equation !

B . g(x) = 4x^2

Putting (2,1) in equation g(x) = 4x^2 , we get :

⇒ $g(2)=4(2)^2$

⇒ $1\neq 64$

Hence , wrong equation !

C . g(x) = (1/4)x^2

Putting (2,1) in equation g(x) = (1/4)x^2 , we get :

⇒ $g(2)= (\frac{1}{4} )2^2$

⇒ $1= 1$

Hence , right equation !

D . g(x) = (1/2)x^2

Putting (2,1) in equation g(x) = (1/2)x^2 , we get :

⇒ $g(2)= (\frac{1}{2} )2^2$

⇒ $1\neq 2$

Hence , wrong equation !

Therefore , g(x) = (1/4)x^2 . correct option C) .

One linear equation is defined by points (1, 6) and (3, 7), while the other is defined by points (3, 6) and (5, 8). Which point

zysi [14]

So we need to find the two lines...y=mx+b where m is the slope and b is the y-intercept.

m=(dy/dx)=(7-6)/(3-1)=1/2 so

y=x/2+b, now I'll use (1,6) to solve for b

6=1/2+b, b=5 1/2=11/2 so

y1=(x+11)/2

now the other line...

m=(8-6)/(5-3)=2/2=1

y2=x+b, using point (3,6) we solve for b

6=3+b, b=3 so

y2=x+3

Since this is just two lines they will only intersect at a single point and when they do, y=y so we can say:

x+3=(x+11)/2

2x+6=x+11

x+6=11

x=5, now use either line to solve for the corresponding y value...

y2=x+3 becomes y=5+3=8 so the solution to this system is the point:

(5,8)

P105a06.sas are the same statistics in the report and data? what do the first 5 rows in the data represent?

ehidna [41]

Since P105a06.sas are the same statistics in the given report and data for this lab, we can infer and logically deduce that the first 5 rows in the data means the statistics are different.

SAS is an abbreviation for Statistical Analysis System and it can be defined as a statistical software suite which was developed at North Carolina State University by SAS Institute for the following field of study:

Business intelligence

Criminal investigation

Data management

Multivariate analysis

Advanced analytics

Predictive analytics

Since it has been stated that P105a06.sas are the same statistics in the given report and data for this lab, we can infer and logically deduce that the first 5 rows in the data means the statistics are different.
