Answer:

0

Explanation:

Given the value of a variable x, the additive inversee will be its negative value.

Hence the additive inverse of x is -x

For a value of 4, then its additive inverse is -4

Taking the sum of 4 and its additive inverse, we will have;

= 4 + (-4)

= 4 - 4

= 0

Hence the sum of 4 and its additive inverse is 0

How do the lengths of the corresponding sides compare? How do you know?

ra1l [238]

Step-by-step explanation:

if two have the same shape, they are called "similar". When two figures are similar, the ratio of the lengths of their corresponding sides are equal. To determine if the triangles show are similar, compare their corresponding sides. Triangles ABC is similar to triangle DEF.

Answer:

a) Josef jogging from A to B;

i. speed = 2 m/s

ii. velocity = 2m/s

a) a) Josef jogging from A to C;

speed = 1.9 m/s

ii. velocity = 2.2 m/s

Step-by-step explanation:

One major difference between speed and velocity is that speed is a scalar quantity, while velocity is a vector quantity.

a) Josef jogging from A to B;

distance = 300 m

time = 2.5 seconds = 150 seconds

i. his average speed = $\frac{distance}{time}$

= $\frac{300}{150}$

= 2 m/s

ii. his average velocity = $\frac{displacement}{time}$

= $\frac{300}{150}$

= 2 m/s

b) Josef jogging from A to C,

distance = 300 + 100 = 400 m

time = 2.5 + 1 = 3.5 minutes

= 210 seconds

i. his average speed = $\frac{distance}{time}$

= $\frac{400}{210}$

= 1.9 m/s

ii. his average velocity = $\frac{\sqrt{V_{1} ^{2} + V_{2} ^{2} } }{2}$

$V_{1} ^{2}$ = 4 m/s

$V_{2} ^{2}$ = 1.9 m/s

his average velocity = $\frac{\sqrt{4^{2} + 1.9^{2} } }{2}$

= 2.2 m/s

A child throws a ball with a speed of 5 feet per second at an angle of 73 degrees with the horizontal. Express the vector descri

maxonik [38]

Answer:

v = 5cos(73°)i +5sin(73°)j

Step-by-step explanation:

The components of the velocity vector are ...

horizontal (i direction): 5·cos(73°)

vertical (j direction): 5·sin(73°)

Then the velocity vector is the sum of these component vectors:

v = 5cos(73°)i +5sin(73°)j

The given series has six terms. what is the sum of the terms of the series? 17 + 25 + 33 + . . . + 57

nikdorinn [45]

Sum of the terms of the series is

Sn = n/2 ( a1+an )

we have n= 6 , a1= 17, an = 57
so Sn = 6/2 ( 17+57) = 3(74) = 222
