Alexis put $2000 in a savings account. After 4 years, she had $2543 in the
account. What rate of interest did she earn? Use the formula A = Pert, where A
[tex]~~~~~~ \textit{Continuously Compounding Interest Earned Amount} \\\\ A=Pe^{rt}\qquad \begin{cases} A=\textit{accumulated amount}\dotfill & \$2543\\ P=\textit{original amount deposited}\dotfill & \$2000\\ r=rate\to r\%\to \frac{r}{100}\\ t=years\dotfill &4 \end{cases}[/tex]
[tex]2543=2000e^{\frac{r}{100}\cdot 4}\implies \cfrac{2543}{2000}=e^{\frac{r}{25}}\implies \log_e\left( \cfrac{2543}{2000}\right)=\log_e\left( e^{\frac{r}{25}} \right) \\\\\\ \ln\left( \cfrac{2543}{2000}\right)=\cfrac{r}{25}\implies 25\ln\left( \cfrac{2543}{2000}\right)=r\implies 6\approx r[/tex]

For which interval is the average rate of change of f(x) negative?
The interval at which the average rate of change of f(x) is negative is from x = 0 to x = 2.5.
What is the average rate of change?The average rate of change is a type of function that describes the average rate at which a quanity decreases or increases with respect to another quanity.
Generally, for a function with a negative average rate of change, the graph must face down and have a negative slope.
Based on the graph shown in the image attached below, we can deduce that the interval for which the average rate of change of f(x) is negative is from x = 0 to x = 2.5.

Answer: 45.25
Step-by-step explanation: Add all the digits together and divide by 8
Mean is the average
Answer:
45.25
Step-by-step explanation:
The mean is the average. Add up all of the values (45+40+47+50+45+49+40+46). This is equal to 362. The amount of values in the set is 8. Divide 362 by 8 to get the mean of 45.25.

Mr Lok is putting a pool in his backyard. His backyard is 10 m long and 8 m wide, while the pool he wants has an area of 8m2. how much grass will be left in his backyard?
Answer:
hope this helps and make me brainliest
Step-by-step explanation:
. You have that:
- The homeowner want the length of the swimming pool to be 4 feet longer than its width.
- He wants to surround it with a concrete walkway 3 feet wide.
- He can only afford 300 square feet of concrete for the walkway.
2. Therefore, the tota area is:
At=L2xW2
L2 is the lenght of the walkway (L2=L1+3+3⇒L2=(W1+4+6)⇒L2=W1+10).
W2 is the width of the walkway (W1+3+3⇒W2=W1+6)
3. The area of the walkway is:
A2=At-A1
A2=300 ft²
4. Therefore, you have that the width of the swimming pool is:
A2=(W1+10)(W1+6)-(W1+4)(W1)
300=(W1²+6W1+10W1+60)-(W1²+4W1)
W1²+16W1+60-W1²-4W1-300=0
12W1-240=0
W1=240/12
W1=20 ft
5. And the length is:
L1=W1+4
L1=20+4
L1=24 ft

-(x-8)²+4
Answer:
-x² + 16x - 60
Step-by-step explanation:
Given expression:
-(x - 8)² + 4Step 1. Insert brackets to isolate the "-" from the (x - 8)².
⇒ -(x - 8)² + 4
⇒ -[(x - 8)²] + 4
Step 2. Use the formula (a - b)² = a² - 2ab + b²
⇒ -[(x - 8)²] + 4
⇒ -[x² - 2(x)(8) + 8²] + 4
Step 3. Open the parenthesis
⇒ -[x² - 2(x)(8) + 8²] + 4
⇒ -x² + 2(x)(8) - 8² + 4
Step 4. Simplify as needed
⇒ -x² + 16(x) - 64 + 4
⇒ -x² + 16x - 60

Answer:
14,200 pounds.
1. Convert the mixed fraction into improper fraction:
To convert a mixed fraction into an improper fraction, we must multiply the whole number with the denominator and add the numerator to the product. The denominator of the improper fraction will remain the same as the denominator in the mixed fraction.
[tex]\implies 7 \dfrac{1}{10} = \dfrac{(7 \times 10) + 1}{10} = \dfrac{71}{10}[/tex]
2. Determine the number of pounds in 71/10 tons
It should be noted that:
Conversion: 1 ton = 2000 poundsNow, let's use the unitary method to determine the amount of pounds in 71/10 tons. Multiply both sides by 71/10 to do so.
[tex]\implies \text{1 ton = 2000 pounds}[/tex]
[tex]\implies \text{1 ton} \times \dfrac{71}{10} = 2000 \times \dfrac{71}{10}[/tex]
[tex]\implies \dfrac{71}{10}\text{ ton} = 200 \times 71[/tex]
Simplify as needed:
[tex]\implies \dfrac{71}{10}\text{ ton} = 14,200 \ \text{pounds}[/tex]

Danny’s supermarket has 1 litter water bottles normally priced at $1.50 reduced 25%
Marta’s supermarket has bottles of water still priced at $1.50 but offer 25% bigger bottle.
Which supermarket has the best buy?
Answer: Danny's supermarket
Step-by-step explanation:
Danny's price- 0.75x1.5= $1.12 for 1 liter water bottle
Marta's price- $1.50 for 1.25 liter water bottle
1.12x1.25=1.40, if Danny was selling a 25% bigger bottle(making the bottle size equal to Marta's) it would cost $1.40, the lower price
