What is the value of (-14^0)^-2?

posledela

Answer:

The value of given expression is 1.

Step-by-step explanation:

The given expression is

$(-14^0)^{-2}$

If a is a real number, then $a^0=1$ .

$(-1)^{-2}$ $[\because a^0=1]$

Using exponent property we get,

$(-1)^{-2}=\frac{1}{(-1)^2}$ $[\because a^{-n}=\frac{1}{a^n}]$

$(-1)^{-2}=\frac{1}{1}$

$(-1)^{-2}=1$

Therefore the value of given expression is 1.

Which expression is equivalent to 4x2 - 4x – 3 in factored form?

erastovalidia [21]

Answer:

(2x-3)(2x+1)

Step-by-step explanation:

4x^2 - 4x - 3

we need two numbers that give 12 when multiplied and 4 when subtracted

the numbers are 6 and 2 because 6*2=12 and 6-4=4.

4x^2 - (6-2)x -3

4x^2 -6x +2x -3

take common

2x(2x -3)+1(2x-3)

take (2x-3) as common

(2x-3)(2x*1 + 1*1)

(2x-3)(2x+1)

If an object is shot with an initial velocity of 160 ft/sec, what is the smallest initial angle will you need to obtain a horizo

MrRissso [65]

To solve the question we shall use the formula for the range given by:
Horizontal range, R=[v²sin 2θ]/g
plugging in our values we get:
500=[160²×sin 2θ]/10
5000=160²×sin 2θ
0.1953=sin 2θ
thus:
arcsin 0.1953=2θ
11.263=2θ
hence:
θ=5.6315°~5.63
