Answer:
(d) scale factor 1/2; center: the origin
Step-by-step explanation:
Consider point B(2, 6). That gets dilated to make point D(1, 3). These coordinates are different, so the center of dilation is not point B. The ratios of the coordinates of D to B are 1/2 and 3/6 = 1/2. This is the scale factor k. (The coordinates of other corresponding points also have the same ratio.)
k = 1/2; dilation center: the origin

Answer:
X1=0+40/8=5(A)
X2=0-40/8=-5(B)
RTA= 5 and -5 are the roots of the equation
Step-by-step explanation:
F(x)=4X^2-100=0
You do BHASKARA in order to get the roots(or zeros)
0(√0-4·4·-100)/2·4=
X1=0+40/8=5(A)
X2=0-40/8=-5(B)
RTA= 5 and -5 are the roots of the equation
Answer:
a₆ ≈ 25.284
Step-by-step explanation:
There is a common ratio between consecutive terms , that is
8 ÷ 6 =
÷ 8 = ![\frac{4}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B3%7D)
This indicates the sequence is geometric with nth term
= a₁ ![r^{n-1}](https://tex.z-dn.net/?f=r%5E%7Bn-1%7D)
where a₁ is the first term and r the common ratio
Here a₁ = 6 and r =
, then
a₆ = 6 ×
= 6 ×
=
≈ 25.284 ( to the nearest thousandth )
