1 3/4 because you need to turn 1 1/2 to 1 2/4 then you add 1 2/4 + 1 3/4 which equals 2 5/4=3 1/4. Then you subtract 5- 3 1/4 = 1 3/4

The table shows the value of an account x years after the account was opened. Based on the exponential regression model, which i

julsineya [31]

Answer:

Correct choice is B

Step-by-step explanation:

The equation of the exponential regression model is $y=a\cdot b^x.$

1. When x=0, $y=a\cdot b^0=a=5,000;$

2. When x=2, then

$y=5,000\cdot b^2=5,510\Rightarrow b^2=\dfrac{5,510}{5,000}=\dfrac{551}{500}=1.102,\ b=\sqrt{1.102}\approx 1.05.$

3. The equation of the function is $y=5,000\cdot (1.05)^x.$ Note that

$y(5)=5,000\cdot (1.05)^5\approx 6,381\approx 6,390;$
$y(8)=5,000\cdot (1.05)^8\approx 7,387\approx 7,390;$
$y(10)=5,000\cdot (1.05)^{10}\approx 8,144\approx 8,150.$

Therefore,

$y(12)=5,000\cdot (1.05)^{12}\approx 8,979\approx 8,980.$

The sum of two numbers, one is as large as the other is 24. Find two numbers

lakkis [162]

Answer:

4 and 20

Step-by-step explanation:

The sum of two numbers is 24.

One of the numbers is 5 times larger than the other.

Let x be the first number.

Let y be the second number.

x + y = 24

x = 5y

Put x as 5y in the first equation.

5y + y = 24

6y = 24

y = 4

Put y as 4 in the second equation.

x = 5(4)

x = 20
