Vertical means in the y-direction
Stretch by factor of 8 means everything is multiplied by 8
so g(x) = 8 * f(x)
= 8 * (3/4 x^2 -1)
= 8*3/4 x^2 - 8*1
= 6x^2 - 8
Answer:
x= -13
Step-by-step explanation:
Step-1 : Multiply the coefficient of the first term by the constant 1 • 13 = 13
Step-2 : Find two factors of 13 whose sum equals the coefficient of the middle term, which is 14 .
-13 + -1 = -14
-1 + -13 = -14
1 + 13 = 14 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, 1 and 13
x2 + 1x + 13x + 13
Step-4 : Add up the first 2 terms, pulling out like factors :
x • (x+1)
Add up the last 2 terms, pulling out common factors :
13 • (x+1)
Step-5 : Add up the four terms of step 4 :
(x+13) • (x+1)
Which is the desired factorization
Answer:
(a) 0.8655
(b)0.8655
Step-by-step explanation:
X is the number of respodents who agree
P(x ≥4), n=12, p=0.45
P(x ≥4)=1-P(x<4)
P(x<4)=P(0 ≤x<4)= P(0 ≤x≤3)=P(x=0,1,2,3)=P(x=0)+P(x=1)+P(x=2)+P(x=3)
P(x ≥4)=1-P(x<4)=1-0.134468=0.8655319
(b)
Y represent those who agree
P(Y≤8), n=12, p=0.45
P(Y≤8)=1-P(Y>8)
P(Y>8)=P(8<Y≤12)=P(9≤Y≤12)=P(Y=9,10,11,12)
Total =0.134468
P=1-0.134468=0.8655319
Answer:
Hi there!
The correct answers are: A, B, D, E
Step-by-step explanation:
First of all, perpendicular means when two lines intersect to form a 90° angle.
Second ⊥ means perpendicular.
When something is a bisector it means it evenly slices a line in half.
