X=( -b+/- √(b²-4ac))/(2a)
x=(-3+/- √(3²-4*2*(-2))/(2*2)= (-3+/-  √(9+16))/4
x(1)=(-3+5)/4=2/4=1/2
x(2)=(-3-5)/4=-2

-4r-8(r-6)=7(5r-1)+8
KATRIN_1 [288]

Answer:

r = 1

Step-by-step explanation:

In this question, we have to solve for the vallue of "r". We will use the distributive property shown below to ease our process.

Distributive Property:

a(b+c) = ab + ac

Now, lets solve this:

-4r-8(r-6)=7(5r-1)+8\\-4r-8r+48=35r-7+8\\-12r+48=35r+1\\48-1=35r+12r\\47=47r\\r=\frac{47}{47}\\r=1

As we have seen the value of r is "1"

One of the children bought their teacher a mathematical plant for the classroom windowsill. At the end of the first day it had i
Vlad [161]

Answer:

  18 days

Step-by-step explanation:

Here's a short table of heights:

  day 0: height = 1

  day 1: height = 1 + (1/2)(1) = 3/2

  day 2: height = (3/2) + (1/3)(3/2) = 3/2 + 1/2 = 2

The pattern of heights is ...

  (day, height) = (0, 1), (1, 1.5), (2, 2)

The plant is growing 1/2 its original height each day, so we can write the equation ...

  h = 1 + d/2

We want to find the number of days (d) that result in a height of 10 (ten times the original height).

  10 = 1 + d/2

  9 = d/2 . . . . subtract 1

  18 = d . . . . . multiply by 2

It took 18 days for the plant to grow to 10 times its original height.

What is the arc measure of AEB in degrees
jasenka [17]

Answer:

305 degree

Step-by-step explanation:

As AD and CE are the diameters of circle P, so that they intersect each other at point P.

=> So that ∡CPA and ∡DPE are two vertical angles.

=> ∡CPA = ∡DPE = 93 degree

As we can see, ∡CPA = ∡CPB + ∡BPA =38 + ∡BPA

=> ∡BPA = ∡CPA - 38 = 93 - 38 = 55 degree

As P is the centre of the circle, so that ∡BPA is equal to the measure of the arc AB, equal to 55 degree.

In the circle P, the total measure of arc AEB and arc AB are 360 degree

=> arc AEB + arc AB = 360

=> arc AEB = 360 - arc AB = 360 - 55 = 305

So that the measure of arc AEB is 305 degree
