Answer:

77

Step-by-step explanation:

Plug in:

F(4) = (4)3 + 2(4)2 + 1

F(4) = 12 + (8)^2 + 1

F(4) = 12 + 64 + 1

F(4) = 77

(assuming 2x2 = 2x squared)

Answer:

\sf x=\boxed{18.21}

Step-by-step explanation:

Assuming this is a right triangle.

<u>Trigonometric ratios</u>

\sf \sin(\theta)=\dfrac{O}{H}\quad\cos(\theta)=\dfrac{A}{H}\quad\tan(\theta)=\dfrac{O}{A}

where:

  • \theta is the angle
  • O is the side opposite the angle
  • A is the side adjacent the angle
  • H is the hypotenuse

Given:

  • \theta = 35°
  • O = x
  • A = 26

\implies \sf \tan(35^{\circ})=\dfrac{x}{26}

\implies \sf x=26\tan(35^{\circ})

\implies \sf x=18.20539599...

Therefore, x = 18.21 (nearest hundredth)

Find the diameter of a circle whose equation is
Olin [163]

Answer:

D) 20

Step-by-step explanation:

x^2 + (y - 2)^2=100

This can be rewritten as

(x-0)^2 + (y - 2)^2=10^2

This is in the form

(x-h)^2 + (y - k)^2=r^2

The radius is 10

The diameter is 2 times the radius

d = 2*r = 2*10 = 20
