Answer:

78. t=8.66yrs

79. r=23.10%

80. r=11.0975%

Step-by-step explanation:

78. Given the initial deposit is $1,000 and the 8% compounded continuously. The doubling time can be calculated using the formula;

$A=Pe^{it}$

Given that A=2P, we substitute in the equation to solve for t:

$A=Pe^{rt}\\\\2P=Pe^{rt}\\\\2=e^{0.08t}\\\\0.08t=\ In 2\\\\t=8.66\ years$

Hence, it takes 8.66 years for $1,000 to double in value.

79.

Given the initial deposit is $1,000 and the r% compounded continuously.

-The doubling rate can be calculated using the formula;

$A=Pe^{rt}$

#We substitute our values in the equation to solve for r:

$A=Pe^{rt}\\\\A=2P, t=3\\\\\therefore\\\\2P=Pe^{3r}\\\\2=e^{3r}\\\\r=\frac{In \ 2}{3}\\\\=0.23105\approx 23.10\%$

Hence, the deposit will double in 3 years at a rate of 23.10%

80.

Given the initial deposit is $30,000 and the future value is $2,540,689.

-Also, given t=40yrs, the rate of growth for continuous compounding is calculated as:

$A=Pe^{rt}, \ \ \ r=r, t=40yrs\\\\2540689=30000e^{40r}\\\\\frac{2540689}{30000}=e^{40r}\\\\r=\frac{In \ (2540689/30000)}{40}\\\\\\=0.110975=11.0975\%$

Hence, the deposit will grow at a rate of approximately 11.0975%

What is the slope of the following equation?

bulgar [2K]

Answer:

the slope is 4/1 which is 4

Step-by-step explanation:

The slope is value of y when x equals to 0, so when you plug in 0 to x it equals to:

y=13(0)+4

y=0+4

y=4

So the slope is 4

A rectangular painting is made up of two congruent squares with sides that are 2 feet long. What is the area of the entire paint

solniwko [45]

Answer:

8 feet²

Step-by-step explanation:

The sides of each square are equal, so the area of one square is 4 feet². If you add the area of that square to the other (which has the same area) you get 8 feet².

Another way to solve it:

Visualize in your head or draw a picture of one of the squares right on top of the other. Combined, the length and width of the rectangle are 2 feet and 4 feet. Since the formula for area is <em>lw=a </em>(<em>l</em>=length, <em>w</em>=width, and <em>a</em>=area)<em>, </em>you multiply 2 by 4 and get 8. Therefore, the area of the painting is 8 feet². Hope this helps.
