I just learned about this!

How to get Number 1: This closed circle represents it is more than or equal to 4. so it should be x ≥ 4.

How to get number 2: This circle is open which means it is NOT equal to or close to the number so it should be x≠-4. Because you don't know how much x is and the lines and arrows represent it is not equal.

Number 3: The first option is the correct one as it says clearly x is less than -3 so it should be a open circle.

Number 4: The 2nd one is right because x is less than -1 or equal to -1.

A balloon is released from a height of 10 feet. The balloon climbs an additional 70% of its previous height as each minute passe
Ainat [17]
The initial height of the balloon is 10 feet which then increases by 70% to (10 ×1.7) = 17 feet, then to (17 × 1.7) =28.9 feet, and so fourth if the rate of increase is kept constant. Therefore, forming a geometric sequence such that to get any term in the sequence we use the formula ar∧(n-1), where a is the first term, r is the common ratio, and n is the term in the sequence. In this case a is 10 and r= 1.7 , to get the height in the fourth minute it means n =5 (for the first term there is 0 minutes, such that for 0 minutes n= 1)
Thus, 10 × 1.7 ∧ 4 = 83.521 feet.
Therefore, the answer is 83.521 feet

Answer:

20%

Step-by-step explanation:

Step 1: Subtract starting value minus the final value (decrease)

\$5.75 - \$4.60\\\\= 5.75 - 4.60 \\\\= 1.15

Step 2: Divide the decrease by the original number

1.15 \div 5.75\\\\= \frac{1.15}{5.75}\\\\= 0.2

Step 3: Multiply the result by 100 to get a percent decrease

0.2 \times 100\\\\= 20

Therefore, the percent decrease of the price of paper per package is 20%

<em>Note: If the percentage is negative, it means there was an increase and not a decrease.</em>

Helppppppppp pleaseeeeeee fasttttt

I think it’s 104,974
Because PEMDAS,
so first deal with exponents and 3 to the fourth power is 81. 6 to the fourth power is 1,296.
Next in PEMDAS is multiplication and division, so 1,296 times 81 is 104,976. Then 4 divided by 2 is 2.
Finally comes subtraction, 104,976 minus 2 = 104,974

Answer:

y = 1500(0.024)^t

Step-by-step explanation:

Given

a = 1500km -- initial area

b = 2.4\% -- rate

t = time --- (years)

Required

Represent as an exponential function

An exponential function has the form:

y = ab^t

Where

a = initial\ value

b = rate and b \ne 1

t= time

Substitute values for a and b, we have:

y = 1500 * (2.4\%)^t

Convert percentage to decimal

y = 1500 * (0.024)^t

y = 1500(0.024)^t

Hence, the exponential function that represents the scenario is: y = 1500(0.024)^t

The circumference of a
timama [110]

9514 1404 393

Answer:

  • 160,000 m²
  • 16 ha

Step-by-step explanation:

The side length of a square is 1/4 of the perimeter, so the side length of the square orchard is (1600 m)/4 = 400 m.

The area of a square is the square of the side length, so the area of the orchard is (400 m)² = 160,000 m².

A hectare is 10,000 m², so the area of the orchard in hectares is ...

  16·(10,000 m²) = 16 ha
