I am pretty sure it’s c because you go up 4 and over 3 to the right so that would be plus 3

Primitive function for: 1. f(x)=4e2x+e−x, sådan att F(0)=2

Free_Kalibri [48]

The primitive function for $f(x) = 4e^{2x} + e^{-x}$ is given by it's indefinite integral.

To calculate it, recall:

$\frac{d}{dx}e^{ax}=ae^{ax}$

$\int c f(x)dx = c\int f(x)dx$

Let's begin

$\int 4e^{2x}+e^{-x}dx \\4\int e^{2x}dx+ \int e^{-x}dx\\4\frac{e^{2x}}{2}+\frac{e^{-x}}{-1} + c\\$

$F(x) = 2e^{2x}-e^{-x} +c$

To find the costant, we just need to use the fact that $F(0)=2$

$F(0) = 2 \\4e^{0}+e^{0} + c =2\\5+c =2\\c=-3$

Therefore,

$\boxed{F(x) = 2e^{2x} - e^{-x} -3 }$

Answer asap! will give brainliest! question is in pic

lana [24]

Answer:

UW=14

Step-by-step explanation:

First we know that UV+VW=UW, so:

4+x+10=2x+14

Solve for x first:

x+10=2x+10

10=x+10

x=0

Then, substitute the X

2(0+14)=14=UW

To check your answer, substitute and add UV and VW

4+(0)+10

Hope this helped! Have a good day!

A jar containing only nickels and dimes contains a total of 60 coins. The value of all the coins in the jar is $4.45. Solve by e

borishaifa [10]

Answer: 31 nickels and 29 dimes

Step-by-step explanation:

Nickels (.05): x

Dimes (.10): y

Value: .05x + .10y = 4.45 → -20(.05x + .10y = 4.45) → -x - 2y = -89

Quantity: x + y = 60 → 1(x + y = 60) → x + y = 60

-y = -29

y = 29

Next, substitute "29" for "y" into either equation and solve for "x":

x + y = 60

x + 29 = 60

x = 31
