Mathematics
1 answer:
aleksandrvk [35]3 years ago
8 0

Answer:

p=-1

Step-by-step explanation:

3x^2+6x-6=0

Add 6 on both sides

3x^2+6x=6

Divide through by 3

x^2+2x=2

Complete the square on the right side

If a quadratic equation is given by

ax^2+bx+c=0

then c=b/2

x^2+2x=2

c=2/2=1

Adding 1 on both sides

x^2+2x+1=2+1

x^2+x+x+1=3

Combining

x(x+1)+1(x+1)=3

(x+1)(x+1)=3

(x+1)^2=3

p=-1

If the 1st and 10th terms of geometric sequence are 4 and 100, find the nth term of the sequence
Masja [62]

a = 4 first term, r = ?, T10 = 100.

Tn = ar^n - 1 formula for g.p

T10 = 4r^ 10 - 1

100 = 4r^9

Divide both side by 4

100/4 = 4/4r^9

25 = r^9 take the 9th root of both side

9√25 = 9√r^9

r = 9√25

To find the nth term

Since Tn = ar^n - 1

Janet is drawing the path formed by the parametric equations x=2+3 sin t and y=1-1/2cos t. Which curve did she draw??
irakobra [83]
Sin²t +cos²t =1

<span> x=2+3 sin t
sin t=(x-2)/3

</span><span>y=1-1/2cos t
y-1= - (cos t)/2 
cos t =-(y-1)/(1/2)

</span>(x-2)²/3² + (y-1)²/(1/2)² = 1
