At the market, 7 apples cost $4.55. How much do 9 apples cost?

Dvinal [7]

7 apples = 4.55
To find the single cost of an apple, divide 4.55 by 7
4.55/7 = 0.65 per apple
Let's check to see if this is right.
0.65 x 7 = 4.55 = correct
0.65 x 9 = $5.85 for 9 apples

What is 28% of 14,350

xenn [34]

Percent means parts out of 100 so
28%=28/100 or 0.28
'of' can be translated as multiply
28/100 times 14,350=401800/100=4018 or
0.28 times 14,350=4018

) Using the chart, approximate the limit of the function f(x) = sin x/ x as x approaches zero. Note the numbers are in radians:

Rashid [163]

Answer:

1

Step-by-step explanation:

We are given that

$f(x)=\frac{sinx}{x}$

Numbers are in radians

Substitute x=-1

$f(-1)=\frac{sin(-1)}{-1}=0.84$

Substitute x=-0.25

$f(-0.25)=\frac{Sin(-0.25)}{-0.25}=0.989$

Substitute x=-0.01

$f(-0.01)=\frac{sin(-0.01)}{-0.01}=0.999$

Substitute x=-0.005

$f(-0.005)=\frac{sin(-0.005)}{-0.005}=0.999$

Substitute x=0.005

$f(0.005)=\frac{sin(0.005)}{0.005}=0.999$

Substitute x=0.01

$f(0.01)=\frac{sin(0.01)}{0.01}=0.999$

Substitute x=0.25

$f(0.25)=\frac{sin(0.25)}{0.25}=0.989$

Substitute x=1

$f(1)=\frac{sin(1)}{1}=0.84$

Therefore, $\lim_{x\rightarrow 0}\frac{sinx}{x}=1$
