Answer:

The second table

Step-by-step explanation:

The second table you described represents an exponential function. It has a common ratio of 4, meaning that each y-value is multiplied by 4 to get to the next value. (every time the Xs increase by 1, the Ys increase by a multiple of 4)

I hope this helps :))

WINSTONCH [101]

Answer:

$\sqrt{13} = D$

Step-by-step explanation:

Method #1

We can draw a right triangle on the graph upon where the points are located and use the Pythagorean Theorem:

${a}^{2} + {b}^{2} = {c}^{2}$

${3}^{2} + {2}^{2} = {c}^{2}$

$9 + 4 = {c}^{2}$

$13 = {c}^{2}$

$\sqrt{13} = c$

* Whenever we talk about distance, we ONLY want the NON-NEGATIVE root.

_______________________________________________

Method #2

We can use the Distance Formula:

$\sqrt{[-x_1 + x_2]^{2} + [-y_1 + y_2]^{2}} = D$

N[−3, 2] M[−6, 0]

$\sqrt{[3 - 6]^{2} + [0 + 2]^{2}} = D$

$\sqrt{[-3]^{2} + 2^{2}} = D$

$\sqrt{9 + 4} = D$

$\sqrt{13} = D$

* Whenever we talk about distance, we ONLY want the NON-NEGATIVE root.

** You see? It does not matter which method you choose, as long as you are doing the work correctly.

I am delighted to assist you anytime.

Answer:

$618.95 rounded up. 0.004c

£388.09 on rent and $230.84 food

We can round up and state $619 to nearest tenth.

Or leave as non rounded Total $618.93

Step-by-step explanation:

27% of 1,437.40=388.09

1,437.40 - 388.09 = 1049.31

22% of 1049.31 = 230.8482

$230,84 Shown here, as not round up or down as 230.84 as £388.09 was not rounded up from 388.098.

= $618.95 rounded up. 0.004c

Solve: |2x+3|-6=11 A) 7 or -10 B) -7 or -10 C) -7 or 10 D) 7 or 10

Inessa [10]

|2x+3| - 6 =11

|2x+3| = 11+6 = 17

2x+3 = 17 or 2x+3 = -17
2x = 17-3, or 2x = -17-3

2x = 14 or 2x = -20
x = 7 or x = -10

7 or -10

Machine A makes 12.75 ounces of popcorn in 3 minutes. Machine B makes 18 ounces of popcorn in 4 minutes.

NARA [144]

Answer:

Machine A makes popcorn at a rate of 4.25 ozs per minute (12.75oz/3min).

Machine B makes popcorn at a rate of 4.5 ozs per minute (18oz/4min).

Machine A will make 4.25oz/min * 10minutes = 42.5oz of popcorn after 10 minutes

Machine B will make 4.5oz/min * 10 minutes = 45oz of popcorn after 10 minutes

After 10 minutes there will be a total of 42.5oz (Machine A) +45oz (Machine B) = 87.5oz.

So the answer is: Yes there will be (more than) enough popcorn if both machines make popcorn for 10 minutes.

If the question is wondering how many 9oz bags they can fill: 87.5oz/9oz per bag = 9.7222 bags. The machines can fill 9, 9oz, bags with some popcorn leftover.

Step-by-step explanation:

Machine A makes popcorn at a rate of 4.25 ozs per minute (12.75oz/3min).

Machine B makes popcorn at a rate of 4.5 ozs per minute (18oz/4min).

Machine A will make 4.25oz/min * 10minutes = 42.5oz of popcorn after 10 minutes

Machine B will make 4.5oz/min * 10 minutes = 45oz of popcorn after 10 minutes

After 10 minutes there will be a total of 42.5oz (Machine A) +45oz (Machine B) = 87.5oz.

So the answer is: Yes there will be (more than) enough popcorn if both machines make popcorn for 10 minutes.

The adjacent sides of a right angle triangle are 5cm and 12cm respectively . calculate the smallest angle of the triangle. How t

lys-0071 [83]

Answer:

22.6 degrees

Step:

The hypotenuse is 13cm using pythagoras theorem.

Now, finding the smallest angle is by using;

SOH

sin = opposite over hypotenuse

Thus, cos^-1 (12/13)

=22.61

and equals to 22.6 (1d.p）
