Answer:

$N=2Z-11$

$\begin{array}{cc}\text{Zac's score}&\text{Natan's score}\\ 6&1\\7&3\\8&5\\9&7\end{array}$

Step-by-step explanation:

Nathan's score is 11 less than 2 times Zac's score.

Let Z points be Zac's score and N points be Natan's score. then

2 times Zac's score = 2Z

11 less than 2 times Zac's score = 2Z -11

So, N = 2Z - 11

1. If Z=6, then $N=2\cdot 6-11=12-11=1$

2. If Z=7, then $N=2\cdot 7-11=14-11=3$

3. If Z=8, then $N=2\cdot 8-11=16-11=5$

4. If Z=9, then $N=2\cdot 9-11=18-11=7$

Thus, four other possibilities are

$\begin{array}{cc}\text{Zac's score}&\text{Natan's score}\\ 6&1\\7&3\\8&5\\9&7\end{array}$

For the following pair of functions, find (f+g)(x) and (f-g)(x).

ch4aika [34]

Given:

The functions are

$f(x)=4x^2+7x-5$

$g(x)=-9x^2+4x-13$

To find:

The functions $(f+g)(x)$ and $(f-g)(x)$ .

Solution:

We know that,

$(f+g)(x)=f(x)+g(x)$

$(f+g)(x)=4x^2+7x-5-9x^2+4x-13$

$(f+g)(x)=(4x^2-9x^2)+(7x+4x)+(-5-13)$

$(f+g)(x)=-5x^2+11x-18$

And,

$(f-g)(x)=f(x)-g(x)$

$(f-g)(x)=(4x^2+7x-5)-(-9x^2+4x-13)$

$(f+g)(x)=4x^2+7x-5+9x^2-4x+13$

$(f+g)(x)=(4x^2+9x^2)+(7x-4x)+(-5+13)$

$(f-g)(x)=13x^2+3x+8$

Therefore, the required functions are $(f+g)(x)=-5x^2+11x-18$

and $(f-g)(x)=13x^2+3x+8$ .

Let me know the answer plz

irinina [24]

Answer:

J

Step-by-step explanation:

Find the common ratio r of the geometric sequence then multiply a term by r to obtain the next term

r = $\frac{a_{2} }{a_{1} }$ = $\frac{6}{-36}$ = - $\frac{1}{6}$

The next 3 terms are

$\frac{1}{6}$ × - $\frac{1}{6}$ = - $\frac{1}{36}$

- $\frac{1}{36}$ × - $\frac{1}{6}$ = $\frac{1}{216}$

$\frac{1}{216}$ × - $\frac{1}{6}$ = - $\frac{1}{1296}$

Which equation represents this situation?

Brut [27]

Answer:

4th option: 38t = 532

Step-by-step explanation:

t = 38
?t = 532
14t =532
I don't really know how to explain this but basically, we know 1t is 38, so we know 38 x t will give use 532. This is why I chose the last equation of:
38t = 532
The answer would be 14 trips just for extra information.

If f(x)=e^2x(x^3+1) then f'(2)=

qaws [65]

Answer:

See below

Step-by-step explanation:

$f(x)=e^2x(x^3+1) = e^2x^4+x$

Considering

$f'(x)=\dfrac{d}{dx}f(x)=\dfrac{d}{dx}e^2x^4+\dfrac{d}{dx}x$

Once the derivative of a constant is 1 and $e^x = \dfrac{d}{dx} e^x$

Then,

$\dfrac{d}{dx}f(x)=\dfrac{d}{dx}e^2x^4+\dfrac{d}{dx}x =\boxed{ e^2 4x^3+1}$

Therefore,

$f'(2) = e^24\cdot 2^3 +1 = 32e^2+1$
