Answer:

2240

Step-by-step explanation:

I think you find 3% of 2000 which is 60

Then you multiply that by 4 which is 240

Add it to the 2000

and get 2240

Answer:

$f(x)=5120(5)^{x}$

Step-by-step explanation:

From the image, f(x) and x are rlated by

$f(x)=a( {b})^{x}$

where b is the common ratio

We first find the value for b

$\frac{6400}{5120}= 5$

$\frac{8000}{6400}= 5$

$\frac{10000}{8000} = 5$

$\frac{12500}{10000} = 5$

$\frac{15625}{12500}=5$

so we can say the common ratio, b=5

we put in any value of f(x) and the corresponding value for x to find a value

Let put x=0 and f(x)=5120

This implies that

$5120 = a(5)^{0}$

but

$5^{0} = 1$

Hence a=5120

Thus the equation which model the relationship between the weeks and the viewers is

$f(x)=5120(5)^{x}$

Select the correct answer.<br> Which function has the same graph as x + y = 11?

Zinaida [17]

The function that has the same graph as x + y = 11 is f(x) = -x + 11

<h3>Graph of functions</h3>

From the question, we are to determine the function that has the same graph as the given equation

The given equation is

x + y = 11

In the above equation, y is the dependent variable.

and

Among the given equation, f(x) is the dependent variable

Thus, we can write that

x + f(x) = 11

Isolate f(x)

f(x) = -x + 11

Hence, the function that has the same graph as x + y = 11 is f(x) = -x + 11

blondinia [14]

Answer:

Step-by-step explanation:

(x,y)=(4,-1)

73x+5y=7

73*4+5*(-1)=287

$287\neq 7$

____________________________

175x−3y=17

175*4-3*(-1)=703

$17\neq 703$

The tangent line to y= f(x) at (4,-6) passes through the point (10,9) Compute the following, f(4) and f'(4)

Anni [7]

The solution to your problem is as follows:

The tangent line passes through (4,-6), so x = 4 when y = -6

=> f(4) = -6

The tangent line will have a constant gradient.

gradient is m = (-6 - 9)/(4 - 10) => 5/2

Equation is y - 9 = (5/2)(x - 10)

=> y - 9 = (5/2)(x-10)

<span>i.e. y = (5/2)(x-10) + 9
</span> y = (5/2)x - 25 + 9 = y = (5/2)x - 16

Now, f '(x) = dy/dx = 5/2

so, f '(4) = 5/2....i.e. gradient is 5/2 whatever the value of x.

I hope my answer has come to your help. Thank you for posting your question here in Brainly.
