Answer:

y > 3\cdot x + 5

Step-by-step explanation:

Let A(x,y) = (-2,4) and y = 3\cdot x + 5. Now we evaluate the given function at x = -2:

y = 3\cdot x + 5 (1)

y = 3\cdot (-2)+5

y = -6 +5

y = -1

Which means that y is less than the y-component of A. Therefore, the right answer is y > 3\cdot x + 5.

The first term in a geometric series is 64 and the common ratio is 0.75. Find the sum of the first 4 terms in the series.
maks197457 [2]

Answer:

195.25

Step-by-step explanation:

Consider geometric series  S(n) where initial term is a

So S(n)=a+ar^1+...ar^n

Factor out a

S(n)=a(1+r+r^2...+r^n)

Multiply by r

S(n)r=a(r+r^2+r^3...+r^n+r^n+1)

Subtract S(n) from S(n)r

Note that only 1 and rn^1 remain.

S(n)r-S(n)=a(r^n+1  -1)

Factor out S(n)

S(n)(r-1)=a(r^n+1  -1)

The formula now shows S(n)=a(r^n+1  -1)/(r-1)

Now use the formula for the problem

I got a tricky one
Yuliya22 [10]

Answer:

D. f(-3) = 11

Step-by-step explanation:

When f(x) is divided by x+3, you get a quotient g(x) and a remainder of 11:

f(x) / (x + 3) = g(x) + 11 / (x + 3)

Multiply both sides by x+3:

f(x) = g(x) (x + 3) + 11

Substitute -3 for x:

f(-3) = g(-3) (-3 + 3) + 11

f(-3) = g(-3) (0) + 11

f(-3) = 11
