For the first graph, part a). The limit of f(x) as x approaches 2 from the LEFT follows the line y = 4, which ends at the hollow point (2, 4). This means that the limit is 4.
First graph, part b), The limit as x approaches 2 from the RIGHT follows y = -1, with a hollow point at (2, -1). This means that the limit is -1.
Second graph: We approach x = 3 from the left, following the downward sloping line which ends at the hollow point (3, -1). This means that the limit is -1.
Third graph: We approach x = 3 from the right, following the horizontal line that ends at (3, 3). This means that the limit is 3.

Note that when talking about one-sided limits, we use the hollow point's y-value which the function approaches. However, when looking at the value of f(x), we would use the solid point.

How do you get 25 for the order of operations

PEMDAS Solve the parentheses first so 9+4=13. Then do the division so 6/6=1. Now the equation is 37- 13+ 1. Then work left to right. 37-13= 24 then 24+1=25.

Can someone help me 1 or 4

sleet_krkn [62]

Answer:

No. 1: y = 90 (vertically opposite angles)

Also, x = 9. To find x, we'll have:

$3x + 7 + 56 + 90 = 180 \\ (sum \: of \: angles \: on \: a \: straight \: line) \\ 3x + 153 = 180 \\ 3x = 180 - 153 \\ 3x = 27 \\ \frac{3x}{3} = \frac{27}{3} \\ x = 9.$

No. 4: y = 62 (vertically opposite angles)

Also, x = 12. To find x, we have:

$5x = 60 \\ \frac{5x}{5} = \frac{60}{5} \\ x = 12.$

A women made a deposit of $196.If her deposit considered of 60 bills, some of them one-dollar bills and the rest being five-doll

raketka [301]

Answer: 26 pieces of $1 bill and 34 pieces of $5 bill

Total Deposit = $196
Total Bills = 60 pieces
Value of $1 = $1
Value of $5 = $5

Lets assume all the 60 pieces were $1 bill.
The total deposit will be 60 x $1 = $60

But we know that the total deposit is $196. So the extra value must have come from the $5.

$196 - $60 = $136
There is still an outstanding amount of $136 not accounted for.

$5 - $1 = $4
The difference in the two bills is $4

Now we can find out the number of $5 bill by dividing the extra $136 by 4:
136 ÷ 4 = 34 pieces

There are 34 pieces of $5 bill.

Since there are 34 pieces of $5, the rest must be the $1 bill
60 - 34 = 26

There are 26 pieces of $1 bill.

There are two cube-shaped tanks. One of the tank has a 3 m side, while the other one has a side measuring half of the first one.

Alexeev081 [22]

Answer: The tank which has 3 m side.

Step-by-step explanation: A cube is a form that has equal sides. To calculate the volume of it, multiply all three sides:

V = length*width*height

Since they are all the same, volume will be:

V = s³

One tank has a 3 m side, so its volume is:

V = 3³

V = 27 m³

The other has half of the first one side, then s = $\frac{3}{2}$ and volume will be:

V = $(\frac{3}{2})^{3}$

V = $\frac{27}{8}$ m³

As you can see, the volume of the second tank is $\frac{1}{8}$ smaller than the first one. Therefore, the tank which has 3 m side can store more water than the tank with side measuring half of the first.
