F (x)=-x^2-2x+1 Zero (s):_______

1 answer:

3 0

F(x) = -x² - 2x + 1
   0 = -x² - 2x + 1
   x = -(-2) ± √((-2)² - 4(-1)(1))
   2(-1)
   x = 2 ± √(4 + 4)
      -2
   x = 2 ± √(8)
      -2
   x = 2 ± 2√(2)
   -2
   x = -1 ± -√(2)
   x = -1 + (-√(2)) U x = -1 - (-√(2))
   x = -1 - √(2)    U    x = -1 + √(2)

AleksandrR [38]

Answer:

40 patients

Step-by-step explanation:

Divide 25 by 5 to get 5 patients per hour (the rate).

Since there are 8 hours, multiply 8 by 5 to get 40 patients in 8 hours.

a tree increases in diameter each year by .51 cm. If the tree currently has a diameter of 4 inches, how old is the tree

yan [13]

This one is a little tricky because of the conversion but .51 cm converts to roughly .2 inches (actually its .200787 but we will round to .2 for ease of math). 4 in/.2in = 20

Therefore the tree is 20 years old.

Footnote 1cm is equal to .3937 inches so it would be .51cm * .3937in = .200787in

I need help with this tri trig I think it’s 55 but I don’t see the answer choice

Answer:

m ∠ W is 58.2°

Step-by-step explanation:

Given:

XY = 15

WZ = 22

∠ XZY =25°

To Find:

m ∠ W = ?

Solution:

In right angle triangle Δ XZY, by Sine identity we have

$\sin Z= \frac{\textrm{side opposite to angle Z}}{Hypotenuse} \\\sin 25= \frac{XY}{XZ}\\0.4226=\frac{15}{XZ}\\\therefore XZ=\frac{15}{0.4226} \\XZ=35.49$

∴ XZ = 35.49

Now in right angle triangle Δ WZX, by tangent identity we have

$\tan W = \frac{\textrm{side opposite to angle Z}}{\textrm{side adjacent to angle Z}}\\\tan W = \frac{XZ}{WZ}\\\tan W = \frac{35.49}{22}\\\tan W = 1.6131\\\therefore W =\tan^{-1}(1.6131) \\W= 58.2\°$

∴m ∠W =58.2°
