6 0

Answer:

27

Step-by-step explanation:

The rule will be

Ni=(i-1)*5+2

  • i=1 → N=(1–1)*5+2=0*5+2=0+2=2
  • i=2 → N=(2–1)*5+2=1*5+2=5+2=7
  • i=3 → N=(3–1)*5+2=2*5+2=10+2=12
  • i=4 → N=(4–1)*5+2=3*5+2=15+2=17
  • i=5 → N=(5–1)*5+2=4*5+2=20+2=22
  • i=6 → N=(6–1)*5+2=5*5+2=25+2=27

I’m not sure if I’m correct but <br> a. Find the slope of the line <br> b. state a point on the line
Agata [3.3K]

the equation of a line in point-slope form is

y - b = m(x - a)

where m is the slope and (a, b ) is a point on the line

y + 1 = \frac{3}{5}(x + 5) is in this form

(a) with slope = \frac{3}{5}

(b) point on the line = (- 5, - 1 ) = (a, b)

Find the probability of rolling a 5 or greater on the first die and a 2 or greater on the second die
bekas [8.4K]

Answer:

The probability is 1/9

Step-by-step explanation:

The probability of rolling a 5 the first time is 1/6

The probability of rolling a number greater than 2

Numbers greater than 2 are 3, 4, 5, 6

So the probability of rolling a number out of these four is 4/6

So the probability of rolling a five for the first time and the probability of rolling a number greater than 2 the second time will be

1/6 * 4/6 = 4/36 = 1/9

Kevin has already read 45 pages in his novel for English. He can read roughly 20 pages each hour. Shania has only read 5 pages s
jolli1 [7]

Answer:

Shania has read the most pages.

Step-by-step explanation:

Following the formula y = mx + b.

Kevin already read 45 pages.

y = mx + 45

He reads 20 pages per hour, since it has per hour, we put it has "m"

y = 20x + 45

Shania already read 5 pages

y = mx + 5

Shania reads 25 pages per hour

y = 25x + 5

We need to find out how many pages they read after 20 hours, plug 20 into x.

Kevin

20(20) + 45 =

400 + 45 =

445

Shania

25(20) + 5 =

500 + 5 =

505

Shania read 60 more pages than Kevin.

A similarity transformation maps `Delta`ABC to `Delta`JKL. The measure of `/_A` of preimage `Delta`ABC is 105°. The scale factor
RoseWind [281]

Please note that dilation does not affect angles. Thus, if an image is dilated the angle remains the same and does not change.

Therefore, even if \Delta ABC is dilated to \Delta JKL by a factor of 1.5 (or by any factor for that matter), the linear dimensions of the original triangle \Delta ABC will either get stretched or get shrunk by a factor of 1.5 but the angles of the original triangle will not be affected in any case.

Please note that this is true for all two dimensional geometric shapes.
