For the function F defined by F(x) = x2 – 2x + 4, find F(b+3).
Ivanshal [37]

Answer:

\displaystyle F(b + 3) = b^2 + 4b + 7

Step-by-step explanation:

We are given the function:

\displaystlye F(x) = x^2 - 2x + 4

And we want to find F(<em>b</em> + 3).

We can substitute:

\displaystyle F(b + 3) = (b + 3)^2 - 2(b+3) + 4

Expand:

\displaystyle = (b^2 + 6b + 9) + (-2b -6) + 4

Rearrange:

\displaystyle = (b^2) + (6b-2b) + (9 - 6 + 4)

Combine like terms. Hence:

\displaystyle = b^2 +4b + 7

In conclusion:

\displaystyle F(b + 3) = b^2 + 4b + 7

Gabriel is designing a rectangular planter box for their garden. It needs to cover an area of 15 1/2 m. Gabriel wants it to be 7
galina1969 [7]

Answer:

2m wide

Step-by-step explanation:

a=lw

15\frac{1}{2} =7\frac{3}{4} w

\frac{31}{2} =\frac{31}{4} w

w=\frac{\frac{31}{2} }{\frac{31}{4} } =\frac{(31)(4)}{(31)(2)} =2

wide = 2m

Hope this helps

How far can a plane fly if it flies at a rate of 170 miles per hour for 4 hours?
Colt1911 [192]
The relationship between space, time and velocity for a uniform motion is given by:
S=vt
where
S is the distance covered
t is the time
v is the velocity

The plane in our problem has a velocity of
v=170 m/h
and so during a total time of t=4 h, the distance it covers is
S=vt=(170 m/h)(4 h)=680 mi
therefore, 680 miles.

So that's the percent that's <u>not</u> there.

Then after that just do the percentage leftover
