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(b + 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:

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

How much force was applied to a 5 kg object if it accelerated by 15 m/s/s

REY [17]

Answer:

We use Newton's second law of motion, which states that,

where:

is the net force applied in newtons

is the mass of the object in kilograms

is the acceleration of the object in meters per second squared

So, we get:

⋅

m/s

(

∵

≡

kg m/s

*PLEASE HELP ME ANSWER THIS, ILL GIVE BRAINLIEST!!!* [ ATTACHMENTS ARE BELOW ]

klasskru [66]

Answer:

Step-by-step explanation:

4) y + 3 / 5 + 3 = x + 2 / 2 + 2

=> y + 3 / 8 = x + 2 / 4

=> y + 3 = 2(x + 2)

5) y - 2 / -1 - 2 = x + 4 / 4 + 4

=> y - 2 / -3 = x + 4 / 8

=> y - 2 = -3/8(x + 4)
