Answer:

it would be 2d - 60

Step-by-step explanation:

Because if you susbtract d from 3d it would be 2d cause d is like a number in this unit

The sum of two consecutive even integers is 186. What are the two numbers?

ozzi

Answer: 92 and 94

Step-by-step explanation:

x = first number

x + 2 = second number

x + x + 2 = 186

simplify

2x + 2 = 186

subtract 2 from both sides

2x = 184

divide both sides by 2

x = 92

92 + 2 = 94

The numbers are 92 and 94.

Average number of jumps on lowest bar = 3/2 = 1.5

Average number of jumps on middle bar = 6/4 = 1.5

Average number of jumps on highest bar = 4/1 = 4

Overall average number of jumps = 3/2 + 6/4 + 4/1 = 7

Overall average number of jumps =

+ 1/probability of complete the lowest bar

+1/probability of complete the middle bar

+ 1/probability of complete the highest bar

Equations of Shane’s overall average number of jumps completed = x * (7/13), where x is the total number of overall jumps.

Determine the function which corresponds to the given graph. (3 points) a natural logarithmic function crossing the x axis at ne

quester [9]

Answer:

$y =log_e(x+3)$

Step-by-step explanation:

It is given that the graph corresponds to a natural logarithmic function.

That means, the function $y$ has a natural log (Log with base $e$ ) of some terms of x.

It is given that asymptote of given curve is at $x= -3$ . i.e. when we put value

$x= -3$ , the function will have a value $y \rightarrow \infty$ .

We know that natural log of 0 is not defined.

So, we can say the following:

$log_e(x+a)$ is not defined at $x= -3$

$\Rightarrow x+a =0\\\Rightarrow x = -a$

i.e. $x =-a$ is the point where $y \rightarrow \infty$

a = 3

Hence, the function becomes:

$y =log_e(x+3)$

Also, given that the graph crosses x axis at x = -2

When we put x = -2 in the function:

$y =log_e(-2+3) = log_e(1) = 0$

And y axis at 1.

Put x = 0, we should get y = 1

$y =log_e(0+3) = log_e(3) \approx 1$

So, the function is: $y =log_e(x+3)$

A boat traveled 37 miles in 2 hours. At this rate, how many miles will the boat travel in

Inessa [10]

Answer:

i. The boat will travel 18.5 miles in one hour

ii. The boat will travel 9.25 miles in half an hour

iii. The boat will travel 27.75 miles in one and a half hours

Explanation:

We are given that the boat travel 37 miles in 2 hours

To get the miles traveled, we can simply use cross multiplication

i. Miles traveled by the boat in one hour:

37 miles .....................> 2 hours

x miles ........................> 1 hour

$x = \frac{37*1}{2}=18.5$ miles

ii. Miles traveled in half an hour:

37 miles .....................> 2 hours

x miles ........................> 0.5 hour

$x = \frac{37*0.5}{2}=9.25$ miles

iii. Miles traveled in an hour and a half:

37 miles .....................> 2 hours

x miles ........................> 1.5 hour

$x = \frac{37*1.5}{2}=27.75$ miles

Hope this helps :)
