You multiply 2/5 by 11 which equals 22/5 hours or 4 2/5 hours

The answer is 4 2/5 hours(4hours 24minutes)

He reads 1/11 book in 2/5 hour.

A whole book is 11/11 of a book.

Multiply by 11.

He reads 11/11 book in 11 * 2/5 hour.

He reads 1 book in 22/5 hour.

22/5 hour = 4.4 hour = 4 hours and 24 minutes

The formula f(x + 1) = Two-thirds(f(x)) defines a geometric sequence where f(1) = 18. Which explicit formula can be used to mode
astraxan [27]

Answer:

The explicit formula is Tn = 18[(2/3)^(n-1)]

Where n is the term we are looking for

Step-by-step explanation:

Here, we want to get an explicit formula to model the equation

Now, F(2) = 2/3 * f1 = 2/3 * 18 = 12

F(3) = 2/3 * f(2) = 2/3 * 12 = 8

F(4) = 2/3 * F(3) = 2/3 * 8 = 16/3

F(5) = 2/3 * 16/3 = 32/9

Thus, seeing how the equations are progressing, we can definitely see a pattern.

That is Tn = (2/3)^(n-1)(18)

What is the slope-intercept form equation of the line that passes through (1, 3) and (3, 7)? (1 point) y = −2x + 1 y = −2x − 1 y
Stolb23 [73]

Answer: y=2x+1

Step-by-step explanation:

The slope of the line is \frac{7-3}{3-1}=\frac{4}{2}=2

Using the point (1,3) to substitute into point-slope form,

y-3=2(x-1)\\\\y-3=2x-2\\\\\boxed{y-2x+1}

Write an expression for the calculation the difference of the products of 5 and 2 and 5 and 1
oee [108]
Let's review the terminology.  A product is what you get when you multiply two numbers.  So, the product of 5 and 2 is basically "5*2," and the product of 5 and 1 is "5*1."

The difference means when you subtract one from the other.  So, the difference of 5*2 and 5*1 means "(5*2)-(5*1)".  (Note: I put in parentheses to make sure the reader understands that 5*2 is separate from 5*1.  5*2-5*1 is confusing: you might not know what to do first!)

So, "(5*2)-(5*1)" can be your answer, OR you can simplify it further by actually doing the multiplication: "10-5".  If you want the answer, just subtract--the expression is equal to 5.

Answer: "<span>(5*2)-(5*1)" OR "10-5" OR "5"</span>
