f(x)=x^4+ax^2+b\\f'(x)=4x^3+2ax\\f''(x)=12x^2+2a\\f''(1)=12(1)^2+2a\\12(1)=-2a\\a=-6\\\\f(x)=x^4-6x^2+b\\(1)=(0)^4-6(0)^2+b\\b=1

a=-6
b=1

Solve the formula, d=r*t for t
larisa [96]

Hello there!

d=rt

Explanation:

↓↓↓↓↓↓↓↓↓

First you had to do is switch sides of the equation.

rt=d

Then you divide by t from both sides of the equation.

\frac{rt}{t}=\frac{d}{t} ; t\neq 0

Simplify it should be the correct answer.

r=\frac{d}{t} ; t\neq 0

Answer⇒⇒⇒⇒⇒ r=d/t or t≠0

Hope this helps!

Can anyone help? thanks in advance!

Answer:

B(2,4)

Step-by-step explanation:

A(-1,-9)

M(0.5,-2.5)

with M we can find x₂ and y₂

x = 0.5

x = x₁+x₂/2

0.5 = (-1 + x₂)/2

(x₂ -1)/2 = 0.5

x₂-1=0.5×2

x₂-1=1

x₂=2

for y₂

y= -2.5

y=(y₁+y₂)/2

y=(-9+y₂)/2

-2.5=(-9+y₂)/2

-9+y₂=-2.5×2

-9+y₂=-5

y₂=-5+9

y₂=4

.: coordinates are B(2,4).
