Answer:

D) 4.7

Step-by-step explanation:

this perpendicular connection with the circle center cuts this intersecting line in half, which is therefore on both sides of x 6.5 long.

I assume 16 is the diameter, so the radius is 8.

therefore, x is one side of the right-angled triangle of

radius

half of the intersecting line

Pythagoras

8² = x² + (6.5)²

64 = x² + 42.25

21.75 = x²

x = 4.7

9. 1/3(x+6) =8

babunello [35]

9. ¹/₃(x + 6) = 8
 ¹/₃(x) + ¹/₃(6) = 8
 ¹/₃x + 2 = 8
 - 2 - 2
 3 · ¹/₃x = 6 · 3
 x = 18

15. ¹/₅(x + 10) = 6
 ¹/₅(x) + ¹/₅(10) = 6
 ¹/₅x + 2 = 6
 - 2 - 2
 5 · ¹/₅x = 4 · 5
 x = 20

20. ¹/₈(24x + 32) = 10
 ¹/₈(24x) + ¹/₈(32) = 10
 3x + 4 = 10
 - 4 - 4
 3x = 6
 3 3
 x = 2

32. 5 - ¹/₂(x - 6) = 4
 5 - ¹/₂(x) - ¹/₂(-6) = 4
 5 - ¹/₂x + 3 = 4
 5 + 3 - ¹/₂x = 4
 8 - ¹/₂x = 4
 - 8 - 8
 -2 · (-¹/₂x) = -4 · (-2)
 x = 8

33. ²/₃(3x - 6) = 3
 ²/₃(3x) - ²/₃(6) = 3
 2x - 4 = 3
 + 4 + 4
 2x = 7

 x = 3¹/₂

Create a report about saving money to assist with the cost of the first year of college

andrew-mc [135]

we should save money to help others in need. i believe this because there are smart homeless kids out there who want and need an education. honestly do you want to be the person who gets a homeless person hooked on drugs because they don't have an education. and there are people with houses but they don't have the kind of money for college and if they do not get that scholarship. their life can take a turn for the worst. as for research 82% of people get hooked up on drugs because they lose their education an can not get a job. this can also lead to depression. that is one of strongest inside damage. it is worse than anxiety thats pretty bad. And it is also how people end up on the streets. And also giving money means study supplies and if thy study their education will most likely get better!!

Area help hellllppppp

slega [8]

Answer:

Area = 14¹/16 yd² or 14.0625 yd²

Step-by-step explanation:

2. The figure given is a square having equal sides of 3¾ yd each.

Formula for area of the square = a²

Where,

a = 3¾ yd

Plug in the value into the equation:

Area = (3¾)²

Change to improper fraction

Area = (15/4)²

Area = 225/16

Area = 14¹/16 yd² or 14.0625 yd²

Use inductive reasoning to find the next term in this sequence 2,3,5,9,17. Then explain the rule for the pattern.

NISA [10]

We have been given the sequence 2,3,5,9,17.

We can write the terms of this sequence as

$2=2^0+1\\
3=2^1+1\\
5=2^2+1\\
9=2^3+1\\
17=2^4+1\\$

From the above term we can see that for the first term we take exponent 0 on 2 and then add 1 .

For second term we take exponent 1 on 2 and then add 1 .

For third term we take exponent 2 on 2 and then add 1 .

Using this fact for the next term of the sequence i.e. 6th term, we can take exponent 5 on 2 and then add 1 .

Therefore, next term of the sequence is given by

$2^5+1\\
=32+1\\
=33$

Therefore, the next term is 33.

Using the above facts, the pattern is given by

$a_n=2^{n-1}+1$
