Answer:

a. 5, 8, 11

b. 32

Step-by-step explanation:

Part A

This is an arithmetic sequence also known as a linear relationship. The rule is 3n+2 for any n terms. So the first term will be n= 1. Substitute and simplify.

3(1) + 2 = 3+2 = 5

Repeat for n= 2.

3(2) + 2 =6+2 = 8

Repeat for n= 3

3(3)+2 = 9+2 = 11

So the first terms in the sequence are 5, 8, and 11.

Part B

The tenth term is when n=10. Substitute and simplify.

3(10)+2 = 30+2 = 32

. Two bicyclists, Sarah and Emily, depart from the same location. Sarah heads N55°E at an average speed of 6 km/hr. Emily heads

Liula [17]

Answer:

The distance between them after 30 minutes is 6.5 km.

Step-by-step explanation:

Speed = $\frac{distance}{time}$

Sarah's speed = 6 km/hr = 1.6667 m/s

Emily's speed = 10 km/hr = 2.7778 m/s

The measure of angle between their bearings = $105^{o}$

After 30 minutes (1800 seconds);

distance = speed x time

Sarah would have covered a distance = 1.6667 x 1800

= 3000 m

= 3 km

Emily would have covered a distance = 2.7778 x 1800

= 5000 m

= 5 km

The distance between them, a, can be determined by applying the cosine rule;

$a^{2}$ = $b^{2}$ + $c^{2}$ - 2bcCos A

= $5000^{2}$ + $3000^{2}$ -2(5000 x 3000) Cos 105

= $5000^{2}$ + $3000^{2}$ -2(5000 x 3000) x (-0.2588)

= 2.5 x $10^{7}$ + 9 x $10^{6}$ + 7764000

= 41764000

a = $\sqrt{41764000}$

= 6462.5073

a = 6462.5 m

The distance between them after 30 minutes is 6.5 km.

5 less than a number is equivalent to 1 more than three times the number<br><br> The number is ??

givi [52]

Answer:

-3

Step-by-step explanation:

Let x equal the mystery number

Our equation will be:

x - 5 = 1 + 3x

Subtract x from both sides

-5 = 1 + 2x

Subtract 1 from both sides

-6 = 2x

Divide both sides by 2

-3 = x
