Mathematics
1 answer:
stich3 [128]3 years ago
8 0

Answer:

0 - 1 - 2 - 3 - 4 - 5

2 - 22.1 - 32.4 - 32.9 - 23.6 - 4.5

Step-by-step explanation:

<u>The function is:</u>

  • H(t) = -4.9t^2 +25t +2

<u>Calculating the value of H for each value of t from 0 to 5</u>

  • H(0) = 2
  • H(1) = -4.9*1^2 + 25*1 + 2 = 22.1
  • H(2) = - 4.9*2^2 + 25*2 + 2 = 32.4
  • H(3) = -4.9*3^2 + 25*3 + 2 = 32.9
  • h(4) = -4.9*4^2 + 25*4 + 2 = 23.6
  • H(5) = - 4.9*5^2 + 25*5 + 2 = 4.5

Correct answer choice is the 3rd one or C

Solve for the value of X.
Mkey [24]
The answer is 40°
i will tell you how,
Total angle sum of any triangle is 180°
∠A + ∠B  + ∠E = 180°
70° + 80° + ∠E = 180°
solve for ∠E
∠E = 30°
Now solve use ∠BDE,
∠B + ∠D + ∠E = 180°
20° + 90° + 30° + x = 180°           (in triangle DEB, ∠E = 30 + x ) (∠D is 90°)
solve for x
there fore, x = 40°

Over a certain region of space, the electric potential is V = 4x − 7x2y + 7yz2. Find the expressions for the x, y, z components
Tju [1.3M]

Answer:

Ex = - 4 + 14xy

Ey = 7x² - 7z²

Ez = -14yz

Step-by-step explanation:

The relationship between Electric field Er(x, y, z) and Electric potential, V, is a differential relationship:

Er(x, y, z) = -dV/dr(x, y, z)

Where r(x, y, z) = distance in x, y and z components.

The x component of the electric field is:

Ex = -dV/dx

Given that:

V = 4x - 7x²y + 7yz²

Ex = -dV/dx

Ex = -(4 - 14xy)

Ex = -4 + 14xy

The y component of the electric field is:

Ey = -dV/dy

Ey = -(-7x² + 7yz²)

Ey = 7x² - 7z²

The z component of the electric field is:

Ez = -dV/dz

Ez = -(14yz)

Ez = -14yz

Which expression is a factor of 9x^2-4x+1 ( ps ^2 is an exponent)
erastovalidia [21]

Answer:

The discriminant b2−4ac < 0, the equation has no real number solutions, it has complex solutions

Step-by-step explanation:

9x² - 4x + 1 = 0     ax² + bx + c = 0

The discriminant: b² - 4ac = (-4)² - 4*9*1 = 16 - 36 = -20

b2−4ac < 0, the equation has no real number solutions, it has complex solutions
