Anastaziya [24]4 years ago

6 0

Step-by-step explanation:

If two lines are mutually perpendicular and going across each other then they will form maximum FOUR 90° angles.

AB is perpendicular to CD. So, FOUR 90° angles will be formed by their intersection.

A team of storm enthusiasts collected data to show the relationship between the time between seeing lightning and then hearing t

never [62]

Answer:

Proportionality constant = $\frac{1}{5}$

Step-by-step explanation:

From the graph attached,

Data set representing the relation between seeing lightning and the hearing thunder is,

{(15, 3), (25, 5), (35, 7), (45, 9)}

Since, Distance from lightening (d) ∝ Time between lightening and thunder (t)

d = kt

Here k = proportionality constant

k = $\frac{d}{t}$

From the data set one point is (15, 3).

k = $\frac{3}{15}$

k = $\frac{1}{5}$ miles per second

Therefore, proportionality constant is $\frac{1}{5}$ miles per second.

ikadub [295]

Answer:

S=157

Step-by-step explanation:

an= a1+(n-1)d

a2=80+(2-1)(-3)

a2=80-3

a2=77

Sn=(a1+an)*n/2

S2=(80+a2)*2/2

S2=(80+77)*1

S2=157
