<em>Hi there!</em>

<em>~</em>

\sqrt{42}<em> ≈ </em>6.4807406984087...

<em>So </em>\sqrt{42}<em> is irrational (since the decimal portion doesn't terminate or repeat) </em>

<em>❀Hope this helped you!❀</em>

I need help with this question asap!
Tpy6a [65]

Answer:

x=15

Step-by-step explanation:

This is an equilateral triangle.  That means all sides are equal and all angles are equal

An equilateral triangle has angle measurements of 60 degrees

60 =4x

Divide each side by 4

60/4 = 4x/4

15 =x

having trouble with this problem, pls help :/ I know the answer, just not how to get there. (ap calc ab, integrals)
pochemuha

Answer: D) 101

Step-by-step explanation:

By linearity, we can break it up into 2 integrals. The integral and derivative of f easily cancel out

\int\limits^{10}_{-1} {(2x+0.5f'(x))} \, dx =\int\limits^{10}_{-1} {2x} \, dx +0.5\int\limits^{10}_{-1} {f'(x)} \, dx =x^2|^{^{10}}_{_{-1}}+0.5f(x)|^{^{10}}_{_{-1}}\\=(100-1)+0.5(f(10)-f(-1))=99+0.5(8-4))=101

I used the table for values of f(x) at 10 and -1. Wouldn't be surprised if this was part of a series of questions about f because I really can't see how you could use the hypothesis that f is twice differentiable on R. Same for the other table values. I'm curious about how you found the answer. Was it a different way?

Light travels 1.08 x 10 9 kilometers in one hour. How far does it travel in 2 hours?
ozzi

The distance traveled by the light in 2 hours is 2.16×10⁹ km.

<h3 /><h3>Distance:</h3>

This is the total length of space between two points covered by an object. Distance has no regard for direction as it is termed a scalar quantity. The S.I unit of distance is meter(m).

To calculate the distance traveled by the light in 2 hours, first, we need to calculate the speed of the light.

Formula:

  • S = d/t................. equation 1

Where:

  • S = speed
  • d = distance travelled
  • t = time

From the question,

Given:

  • d = 1.08×10⁹ km
  • t = 1 hour

Therefore,

  • s = 1.08×10⁹/1
  • s = 1.08×10⁹ km/h

The distance traveled in 2 hours is

  • d = 2×1.08×10⁹
  • d = 2.16×10⁹ km

Hence, the distance traveled by the light in 2 hours is 2.16×10⁹ km

Line A has an equation of y=-2/5x + 3. What is the slope of a line perpendicular
Nat2105 [25]

Answer:

\frac{5}{2}

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - \frac{2}{5} x + 3 ← is in slope- intercept form

with slope m = - \frac{2}{5}

Given a line with slope m then the slope of a line perpendicular to it is

m_{perpendicular} = - \frac{1}{m} = - \frac{1}{-\frac{2}{5} } = \frac{5}{2}
