Answer:

50 degrees

Step-by-step explanation:

You know it's a right angle, so that means it is 90 degrees, just subtract 40 degrees from 90 since you know a = 40 and a+b=90

Answer:

90 (degrees) - a = b

90 (degrees) - (40) = 50 (degrees)

Step-by-step explanation:

The little box in the corner indicates that it is a right angle, all right angles are equal to 90 degrees.

They gave you the value of (a) and we know that (b) must be equal to 90 degrees when added to (a).

Subtract 90 from 40 and that gives you fifty degrees.

Is x-3 a factor of the polynomial p(x)=2x4-9x3+15x2-22x+12 and for waht reason
andre [41]
Yes, (x - 3) is a factor of the given polynomial.

If (x - 3) was a factor of the polynomial, then 3 would be one of the zeros of the function. That means if you input 3 into the function, you will get an output of zero.

In this case, inputting 3 does produce 0. Therefore, it is a factor.

Eva has borrowed 200 songs from her friend. She plans to download an equal number of songs on her music player each week for 5 w
Alenkasestr [34]

PART A)

The rate of change is -40 songs each week, because the amount of songs left to be downloaded decrease by 40 every week.

<span>the initial value is 200 at 0 weeks, which means that there are 200 songs to be downloaded at the beginning</span>

PART B)

<span><span><span> <span><span>calculate the slope:
</span><span> m = (y2- y1)/(x2 - x1) = (160 - 200)/(1 - 0)
m = -40
now use the line equation in form of point-slope
y - y1 = m(x - x1)
y - 200 = -40(x - 0)
y = -40x + 200</span></span> </span></span></span>

What is the simplified form of the following expression? 5sqrt 8-sqrt18-2sqrt2
spayn [35]

Answer:

5 sqrt2.

Step-by-step explanation:

sqrt8 = sqrt4 * sqrt2 = 2 sqrt2

sqrt18 = sqrt9 * sqrt2 = 3 sqrt2

So simplifying:

5sqrt 8 - sqrt18 - 2 sqrt2

= 5*2sqrt2 - 3 sqrt 2 - 2 sqrt2

= 10 sqrt2 - 5 sqrt2

= 5 sqrt2 (answer).
