7 0

Answer:

7n-4;696

Step-by-step explanation:

I look at it as having ordered pairs (1,3), (2,10), (3,17), etc

looks like the y's increase by 7 for every increase of 1 in the x's, so the slope = 7

thus y = 7x + b

plug in (1,3) ----> 3 = 7 + b or b = -4

y = 7x - 4

in sequence terms: termn = 7n - 4

term100 = 7(100)-4 = 696

find the standard form of the equation of an ellipse that has a major axis of length 6 and fox at (-2,0) and (2,0)

Ksivusya [100]

Let the equation be $\frac{x^2}{a^2}+\frac{y^2}{b^2}=1$
because the length of major axis is 6, 2a=6. then a=3, a²=9.
c=2, $a^2-b^2=c^2$ , so $b^2=5$
therefore, the equation is $\frac{x^2}9+\frac{y^2}5=1$

if right please mark me brainliest, thanks.

Answer:

S1) False. 2³ is 2 × 2 × 2 which is 8, not 6.

S2) False. ( 2x / 3y ^ (2) ) ^ (3) =

( (2x) ^ (3) / ( (3y) ^ (2) ) ^ (3) ) = (2)³ × (x)³ / (3)³ × (y²)³ = 8 × x³ / 27 × y⁶ = 8x³ / 27y⁶.

i.e (a^b)^c = a^(b × c).

S3) True.

S4) True.

S5) False. x^(-3) = 1 / x^(3) ≠ 1 / 3x
