Given that F( x ) = x 2 + 2, evaluate F(1) + F(5).
stealth61 [152]

Hi there! :)

Answer:

\huge\boxed{f(1) + f(5) = 30}

Given:

f(x) = x^{2} + 2

Evaluate f(1) + f(5)

Solve for each:

f(1) = (1)^{2} +  2 = 3

f(5) = (5)^{2} + 2 = 27

27 + 3 = 30

PLEASE HELP URGENT<br><br> Given \tan \theta =0.6, find the value of b.
xxTIMURxx [149]

Answer:

b=8.5cm

Step-by-step explanation:

tanx (this represents tan theta, it's just easier to type) is equal to 0.6 and since the tanx ratio is opp/adj, we know that opp/adj = 0.6

To find what b is (adjacent as it is adjacent to the angle being used and it is not the hypotenuse), we just have to rearrange.

0.6=5.1/adj

to solve for adj, we can switch 0.6 and adj. (This works because to get adj by itself on one side you would multiply it to the other side and then divide 0.6 from both sides --> simple algebra)

so then you have

adj=5.1/0.6

adj=8.5cm

(if you want to check your solution you can use pythagoeran theorem, a^2+b^2=c^2) and sub everything in and make sure all the numbers equal the right thing!

The slope of a line is negative for use the cordons of the labeled point to find a point-slope equation of the line.
Alexeev081 [22]
For slope m and point (x₁, y₁), the point-slope equation of the line can be written as
  y -y₁ = m(x -x₁)

You have m = -4 and (x₁, y₁) = (4, -9), so the equation of your line is
  D. y+9 = -4(x-4)
