Answer:

h(2) = 5.2 + 1 = 10 + 1 = 11

Answer:

y = 1/2x - 6

Step-by-step explanation:

Here, we want to get the equation of the line that passes through the given points

Mathematically we can write the equation of a line as;

y = mx + b

where m is slope and b is the y-intercept

We start by getting the slope

m = (y2-y1)/(x2-x1)

m = (-1+5)/(10-2) = 4/8 = 1/2

So we have the equation partially as;

y = 1/2x + b

to get c, we use any of the two points and substitute the individual x and y values

-1 = 1/2(10) + b

-1 = 5 + b

b = -1-5 = -6

so the equation is;

y = 1/2x - 6

The correct question is

A watch loses 30 secs every hour .If the watch was set right on Sunday 11:30pm .What is time did it show after 10 hours?

(a) Monday 9:25am

(b) Monday 9:30 am

(c) Monday 9:35

(d) Monday 9:25pm

Answer:

(a) Monday 9:25am

The time shown by the watch in 10 hours from its starting at 11:30pm on Sunday will give 9:25am on Monday.

Step-by-step explanation:

We are given that a watch looses 30 seconds in one hour and the Watch was set on 11:30pm on Sunday.

we need to find the time this watch will show after 10 hours from starting at 11:30pm on Sunday.

In 1 hour = 30 seconds is lost

In 10 hours = 30*10 = 300seconds

Converting 300 seconds into minutes we get

 = 300/60 = 5 minutes

This means whatever the actual time will be this watch will shows 5 minutes less.

10 Hours from 11:30pm on Sunday will be

9:30am on Monday morning

but since the watch is slow by 30 seconds each hours which will make 5 minutes difference from the real time in 10 hours so the time shown by the watch will be

9:25am on Monday morning.

Therefore the time shown by the watch in 10 hours from its starting at 11:30pm on Sunday will give 9:25am on Monday.

THE ANSWER IS -6.246

Step-by-step explanation:

Answer:

Greater than 4.256

• Remove minus in the exponent and invert the base:

= (1/22)5

• Expand the multiplication:

= (1/22) * (1/22) * (1/22) * (1/22) * (1/22)

• Find your result:

= 1/5153632 ≈ 0.000000194038

Answer:

4.5%

Step-by-step explanation:

Equation that models this:

Plugging in t= 10 years, gives

1553 = 1000 (1+interest)^10

solving for interest gives: 0.045 which is 4.5%

Answer:

Step-by-step explanation:

The answer is false because 15 + 12 does not equal 220

15 + 12 = ?

It equals 27 if you got your calculations right.

You could also find out if the answer is right if you subtract 220 by one of the numbers ( 15 or 12 ) and if you get the number that you didn't subtract, then that is correct.

Here's an example.

220 - 15 = ?

220 - 15 = 205

205 does not equal 12, so it is wrong or F A L S E.

Answer:

A= 41°   a=9.84...  b=11.32...

Step-by-step explanation:

given B = 49° and C = 90°

and A + B + C = 180

so  49+90+A=180

A= 41°

we also know c (small)  is 15 units

and maybe you know this  SOH CAH TOA?   no, i'm not calling anyone names :P  this is just the mnemonic to memorize how sin , cos and tan fit sin(Ф)=Opp/Hyp   Cos(Ф)=Adj/Hyp  Tan(Ф)=Opp/Adj

Hyp is the hypontenuse of the triangle ( the long side). Opposite (Opp) means the side opposite from what ever angle you are starting at..adjacent (Adj) means what ever angle is next to where you are starting from.

use Cos(49) to find the side a

a is an adjacent side to the 49 angle.  We know the Cos and we know the Hyp .. so solve for adj...  

Cos(Ф)=Adj/ Hyp

Hyp*Cos(Ф)=Adj    

15*Cos(49)= Adj

9.84...=Adj=a

now lets' use sin for the opposite side or b

sin(Ф)=Opp/Hyp

Hyp*Sin(Ф) = Opp

15*sin(49)= Opp

11.32...= Opp =b
