Answer:

\sum_{n=1}^{14}(3n-28)

Step-by-step explanation:

The given series is

-25-22-19+...

The the first term of the sequence is;

a_1=-25

The constant difference is;

d=-22--25

d=3

The nth term of the series is

a_n=a_1+d(n-1)

a_n=-25+3(n-1)

a_n=-25+3n-3

a_n=3n-28

Using the summation notation, we can write the series as;

\sum_{n=1}^{14}(3n-28)

Answer:

  (2, 14), (3, 7)

Step-by-step explanation:

The way these angles are numbered, corresponding angle numbers differ by 4, 8, or 12.

Corresponding angles are ...

  Angle 2 and Angle 14 . . . . . . numbers differ by 12

  Angle 3 and Angle 7 . . . . . . . numbers differ by 4

_____

If a given angle is Northwest of the intersection, any corresponding angle will also be Northwest of its intersection. Corresponding angles are ...

  northwest: {1, 5, 9, 13}

  northeast: {2, 6, 10, 14}

  southeast: {3, 7, 11, 15}

  southwest: {4, 8, 12, 16}

Any pair of numbers from the same set will be corresponding angles.

What is the value of x in the equation log5 x = 4 jmap?
steposvetlana [31]
To solve for x we proceed as follows:
from the laws of logarithm, given that:
log_a b=c
then
a^c=b
applying the rationale to our question we shall have:
log_5 x=4
hence
5^4=x
x=625
Answer: x=625

spayn [35]

Answer:

360 in.

Step-by-step explanation:

In order to get this answer, you have to multiply 5 and 8 by 3 because the drawing is 1/3 of the actual flag.

5 x 3 = 15

8 x 3 = 24

So, 24 x 15 = 360 in.

Hope this helps! :)

You start at (5, 3). You move down 3 units and left 6 units. Where do you end?
raketka [301]

Answer:

(-1, 0)

Step-by-step explanation:

5 is the x value which is left and right, so you said u move left 6 units. Since the 5 is positive and left is negative; 5-6= -1. 3 is the y value which is up and down (vertical), so you said u move down 3 units, since the 3 is positive, when you move down that is negative; so 3-3=0.

Find the angle of least nonnegative​ measure, θC​, that is coterminal with θ=<br> 9π/4.
Lostsunrise [7]

9514 1404 393

Answer:

  θC = π/4

Step-by-step explanation:

To find the desired angle, subtract multiplies of 2π until the angle is in the desired range.

  9π/4 -2π = (9-8)π/4 = π/4

The angle θC = π/4 is coterminal with θ = 9π/4.
