9 (x− 3 =) 45 pleas answer fast
GalinKa [24]

Answer: x = 8

Step-by-step explanation:

9 ( x - 3 ) = 45

distribute 9

9x - 27 = 45

combine constants

9x = 45 + 27

compute 45 + 27

9x = 72

divide both by 9

9x/9 = 72/9

final answer

x = 8

Approximate cos (12π/ 13) by using a linear approximation with f (x) = cos x.
Katarina [22]
First pick a value of x close to \dfrac{12\pi}{13}. You should be fine with x=\pi.

The linear approximation of f(x) at x=c is given by

f(c)\approx f(a)+f'(a)(c-a)

where x=a is some fixed value close to x=c. You have

f(x)=\cos x\implies f'(x)=-\sin x

so

f\left(\dfrac{12\pi}{13}\right)\approx f(\pi)+f'(\pi)\left(\dfrac{12\pi}{13}-\pi\right)
\cos\dfrac{12\pi}{13}\approx\cos\pi-\sin(\pi)\left(-\dfrac\pi{13}\right)
\cos\dfrac{12\pi}{13}\approx-1

The actual value is closer to -0.9709, so the approximation is decent.

Use the function below to find F(2)<br><br> F(x)=1/3•4^x
AnnZ [28]

Answer

The answer is 16/3

Step-by-step-explain

F(x) = ⅓ • 4ˣ, F(2)

F(2) = ⅓ • 4²

F(2) = ⅓ • 16

F(2) = 16/3

Thus, The answer is 16/3

2 1/4 cups of cream for 5 people. How much cream will you use for 8 people?
dybincka [34]
2 1/4 = 2.25 to find the value of one person u do the equation 2.25 divided by 5 which is 0.45 to find your answer you multiply the amount of cream for one person 0.45 by 8 which is 3.6 and 3.6 as a fraction is 3 3/5 so your answer I believe is 3 3/5
