Look at the geometry question and solve for X.
zubka84 [21]

Answer:

The value of x = 24.4 units.

Step-by-step explanation:

Given

  • a = 14
  • b = 20
  • c = x

For a right-angled triangle with sides a and b, the hypotenuse  c is defined as

c=\sqrt{a^2+b^2}

substituting c = x, a = 14 and b = 20

c=\sqrt{14^2+20^2}

c=2\sqrt{149}

c = 24.4 units

Therefore, the value of x = 24.4 units.

What is the axis of symmetry of the quadratic function y=2(x+3)^2+5
Pavel [41]

Answer:

x=-3

Step-by-step explanation:

The quadratic function y=2(x+3)^2+5 determines the parabola which has the vertex at point (-3,5). The axis of symmetry passes through the vertex and is parallel to the y-axis. Hence, its equation is x=-3 (see attached diagram).

A line passes through the point (0,2) and has a slope of -1/4. What is the equation of the line
Dennis_Churaev [7]

Answer:

Step-by-step explanation:

use point-slope formula [y-y1 = m(x-x1) ] with the given info

P=(x1,y1) = (0,2)  and slope m = -1/4

y-2=-1/4(x-0)

y-2= -1/4x

now try to move things till you get the slope-intercept form [y=mx+b]

y= -1/4x+2

good all done :)
