What number exceeds 23 by 4 more than twice the amount by which 15 by -3

hodyreva [135]

Answer:

The required number is 63

Step-by-step explanation :

Let the number be x

Now As per question , the equation is written as

x - 23 = 2 × [ 15 - ( - 3) ] + 4

Or, x - 23 = 2 × ( 18) + 4

Or , x - 23 = 36 +4

Or, x - 23 = 40

So, x = 40 + 23

∴ x = 63

Hence the required number is 63 Answer

E = MV^2 ÷ 2 + mgh, Make V Subject of the formula

Stels [109]

Answer:

$\red{ \bold{ V = \sqrt{\frac{2(E - mgh)}{M}}}}$

Step-by-step explanation:

$E = MV^2 ÷ 2 + mgh \\ \\ E - mgh = MV^2 ÷ 2 \\ \\ 2(E - mgh)= MV^2 \\ \\ \frac{2(E - mgh)}{M}=V^2 \\ \\ \sqrt{\frac{2(E - mgh)}{M}} = V \\ \\ \red{ \bold{ V = \sqrt{\frac{2(E - mgh)}{M}}}}$

According to the Rational Root Theorem, the following are potential roots of f(x) = 2x2 + 2x – 24.

Andrei [34K]

Answer:

The answer is 3 and (-4).

Step-by-step explanation:

We are given an equation 2x² + 2x – 24.

Let us assume that the equation is equal to zero.

2x² + 2x – 24 = 0

Now, divide whole equation by 2 we get,

x² + x – 12 = 0

x² + 4x – 3x – 12 = 0

x(x + 4) – 3(x + 4) = 0

(x – 3) (x + 4) = 0

x = 3, -4

Thus, The actual roots of f(x) are 3 and (-4).
