W² - v + 1

(-2)² - (-8) + 1

4 + 8 + 1 = 13

B.13 is your answer

(two negatives = one positive)*
(plug in -2 for w, and -8 for v)
(is that w², or do you mean 2w?)

hope this helps

!!!PLEASE HELP ASAP!!! I WILL GIVE MORR POINTS IF NEEDED AND MARK BRAINLIEST

Firlakuza [10]

The first one shows 1 cm and 7 mm, we need to convert 7 mm to cm
1 cm + 7 mm
= 1 cm + $\frac{7}{10}$ cm
= 1 cm + 0.7 cm
= 1.7 cm
The first one is 1.7 cm

The second one shows 11 inches and 5/16 inches. Between number 11 and 12, there are 16 strips and the pointer lies on fifth strip, thus it show 5/16 inches. The second one is 11 $\frac{5}{16}$ inches.

The third one shows 13 cm and 8 mm. We need to convert mm into cm.
13 cm + 8 mm
= 13 cm + 0.8 cm
= 13.8 cm
The third one is 13.8 mm

What is the sum of the first thirteen terms in a geometric series with a r = 3 a1= -10

Ipatiy [6.2K]

To calculate the sum of the first thirteen terms of the geometric series, we use the formula below.

Formula:

S₁₃ = a(rⁿ-1)/(r-1).............. Equation 1

Where:

S₁₃ = Sum of the first thirteen terms of the geometric series.
a = First term of the series
r = Common ratio

Given:

a = -10
r = 3
n = 13

Substitute these values into equation 1

S₁₃ = -10(3¹³-1)/(3-1)
S₁₃ = -7971615
