Since you don't need to submit a scatter plot, you can just look at the table and see if you want to use an exponential graph or logarithmic graph. First, you need to know the properties of the two graphs. An exponential graph has pretty slow growth at the beginning, and then rapid and extremely fast growth toward ∞. On the other hand, ㏒(x) function starts out very fast but slows down as it gets closer to its asymptote and then it's the slowest thing ever.

This data starts out on a relatively big jump in 6 years, then it grows just a little (because the log(x) function is like that remember) and then it slows down a whole lot. In fact, from a rate 19.67 from the first two years to a rate of 6 in the last two years. So, it would be ideal if you use the logarithmic function - it is the best choice for graphing this data. This is how I would work through it :)

Help please and that you 13-16

Answer:

See explanation.

Step-by-step explanation:

13. (4*5)/2 = 10

14. 5*7=35 7-3=4 8-5=3 (4*3)/2 = 6 35+6 = 41

15. 3*4 = 12

16. (4*4)/2 = 8 8*4=32 4*2=8 16*8=128 128-32 = 96

Let me know if you want me to better explain how I solved any of these.

Drag the tiles to the table. The tiles can be used more than once, but not all tiles will be used.

Sav [38]

Answer:

Emma can complete the calls alone in 6 days, which means she can complete $\frac{1}{6}$ of the calls in one day. So, Emma’s rate per day is $\frac{1}{6}$ . Jackson can complete the calls alone in $4$ days, which means he can complete $\frac{1}{4}$ of the calls in one day. So, Jackson’s rate per day is $\frac{1}{4}$ . Because they’re working together, the time, $x$ , is the same for both.

Multiply across the table to find the part of the task each has completed. Use the equation work completed = (rate)(time) to fill in the last column cells.

What is an appropriate scale for $35

Soloha48 [4]

A bar graph. This would be what you would use. I don't know if I misinterpreted your question, but let me know if you still need help. I hoped I helped!

The points (–1,–1) and (a,–5) fall on a line with a slope of 4. What is the value of a?<br> a=

Andreas93 [3]

Answer:

The value of a is -2

Step-by-step explanation:

We are asked to give the value of a

We are provided with some information

We are given slope to be 4

And two points ( -1 ,-1) and

( a, -5)

Given the formula for slope

m = y_2 - y_1 / x_2 - x_1

Points ( -1 , -1)

(a, -5)

x_1 = -1

y_1 = -1

x_2 = a

y_2 = -5

Inserting the values given into

m = y_2 - y_1 / x_2 - x_1

= -5 - (-1) / a - (-1)

= -5 + 1 / a + 1

= -4 / a + 1

We are given the slope to be 4

i. e. m = 4

4 = -4 / a + 1

Cross multiply

4( a + 1) = -4

Open the bracket with 4

4a + 4 = -4

Collect like terms

4a = -4 - 4

4a = - 8

Divide both sides by 4 to get the value of a

4a / 4 = -8/4

a = -2

Therefore, x_2 = -2

the value of a = -2

One container holds 1 7/8 quarts of water and A second container holds 5 3/4 quarts of water how many more quarts of water does

BartSMP [9]

$5 \frac{3}{4} -1 \frac{7}{8} = \frac{23}{4} - \frac{15}{8} = \frac{46}{8} - \frac{15}{8} = \frac{46-15}{8} = \frac{31}{8} = \boxed {3 \frac{7}{8} }$
