Answer:

0.0025

Step-by-step explanation:

Given that the value of s = \frac {0.1}{4}

TO calculate the value of the expression - 4\times s^2

Since, s = \frac {0.1}{4}

On calculation, s = 0.025

Putting the value in the equation as shown below as:

= 4\times {(0.025)}^2

= 0.0025

<u>Hence, the answer from the given value of s = \frac {0.1}{4} is - 0.0025</u>

Find the gradient of the line segment between the points (-4,-5) and (2,-4).
Anna11 [10]

Answer:

   1/6

Step-by-step explanation:

The gradient of the line segment is the same as slope

m = (y2-y1)/(x2-x1)

   = ( -4 - -5)/( 2 - -4)

   = (-4+5)/( 2 +4)

   1/6

One-third of a number t is less than or equal to 5
Kryger [21]

Answer:

t ≤ 15

Step-by-step explanation:

One third of 15 is equal to five (1/3 × 15 = 5)

One third of t is lesser than or equal to five (1/3 × 5 ≤ 5)

<em>So, t cannot be more than 15.</em><em> </em><em>It</em><em> </em><em>can</em><em> </em><em>be</em><em> </em><em>equal</em><em> </em><em>to</em><em> </em><em>1</em><em>5</em><em>,</em><em> </em><em>though</em><em>.</em>

∴t ≤ 15

Evaluate the expression (25^-3/2)^1/3
Brilliant_brown [7]

Answer:

1/5

Step-by-step explanation:

To avoid ambiguity, your negative exponent -3/2 should be enclosed in brackets or parentheses, as should your exponent 1/3:

( 25^[-3/2] )^ (1/3)

This is equivalent to:

(√25)^(-3)· (1/3), or

5^(-1), or 1/5.

You are watching a game of poker on ESPN with your friends. You are trying to figure out the value of each colored chip that is
klasskru [66]

9514 1404 393

Answer:

  N = 5; only one rate is possible

Step-by-step explanation:

The values of the sets of chips are ...

  12 +9N +8N^2 +4N^3

and

  2 +N +N^3 +N^4

We want to find N such that the difference in value is zero:

  N^4 -3N^3 -8N^2 -8N -10 = 0

A graphing calculator can show us the roots. There is only one positive real root to this equation: N = 5.

The exchange rate N is 5. Only one rate is possible.

K^2+8k-9=0 can you help me solve with showing work
givi [52]
Using the PSN method:

P = -9
S = 8
So N = 9,-1

Using 9 and -1 in the original equation gives:

k^2+9k-k-9=0&#10;\\k(k+9)-1(k+9)=0&#10;\\(k-1)(k+9)&#10;&#10;\\\\k=1,-9
