What is the slope and y-intercept of this graph?​
pantera1 [17]

9514 1404 393

Answer:

  $0 -- y-intercept

  $10 per hour -- slope

Step-by-step explanation:

We would need to see grid lines on the graph, or the point in the upper right corner to be sure. It appears as though the slope is about $40 / 4 h, or $10 per hour.

The y-intercept is the point at lower left, (0, 0).

Select the correct answer from each drop-down menu.
marusya05 [52]

Answer:

(1) If the GCD of 5 and 12 is 1, then they are co-prime.

(2) The sum of 5 and 12 is 7 if and only if 5 is a negative integer.

Step-by-step explanation:

(1)

The GCD (greatest common divisor) of two or more numbers, which are not all equal to zero, is the largest positive integer number which divides each of the numbers.

If the GCD of two numbers is 1, then the two numbers are known as coprime or relatively prime or mutually prime.

(2)

The sum of 5 and 12 is 7 if and only if, the number 5 is a negative integer, i.e.

-5 + 12 = 7

36a^2+24b^2=12( +2b^2)
vlabodo [156]
The blank space is found by dividing 36a^2 by 12, which is equal to 3a^2
To get to this answer you need to
1. divide the both sides of the equation by 12.
2. subtract 2b^2 from both sides. 
You will see that the blank space equals 3a<span>^2 then</span>

What interest rate per annum is a fund paying its clients if the third to the last payment of a depositor became Php 1,040.40 fr
Ainat [17]

Answer: The rate of interest per annum is 1.3%.


Step-by-step explanation:

Given  Principal P= $1000

time period n=3

Amount A=$1040,40

To find rate of interest per annum r

We know that

A=P(1+\frac{r}{100} )^3\\\Rightarrow\ 1040=1000(1+\frac{r}{100})^3\\\Rightarrow\ 1.040=(1+\frac{r}{100})^3\\\text{taking log on both sides}\\log(1.040)=3log(1+\frac{r}{100})\\\Rightarrow0.039=3log(1+\frac{r}{100})\\\Rightarrow0.013=log(1+\frac{r}{100})\\\\\Rightarrow\ e^{0.013}=(1+\frac{r}{100})\\\Rightarrow\ 1.013=(1+\frac{r}{100})\\\Rightarrow\ \frac{r}{100}=1.013-1=0.013\\

⇒  r = 1.3%.
