Answer:

D is the answer.

16x {}^{2}  - 81 = 0 \\ (4x - 9) \times (4x + 9) = 0 \\

4x - 9 = 0  \\ 4x = 9 \\ x =  \frac{9}{4}  \\ or \\ 4x + 9 = 0 \\ 4x =  - 9 \\ x =  -  \frac{9}{4}

98 POINTS!!!<br><br>Write a polynomial function in standard form given the zeros<br><br><br>±√5 , 7
Neporo4naja [7]

Answer:

Step-by-step explanation:

Knowing the three zeros of the equation, we can set it up as follows:

(x - \sqrt{5})(x + \sqrt{5})(x - 7)

Multipying the first two expressions together gives us the following:

(x^{2} - 5)(x - 7)

Multiplying the two expressions together gives us the following:

x^{3} - 7x^{2} - 5x + 35

A bouncing ball reaches a height of 54 inches at its first peak, 36 inches at its second peak, and 24 inches at its third peak.
steposvetlana [31]
54, 36, 24 are the 1st 3 element of a geometric progression with 2/3 as a common ratio: PROOF:
the 1st term is 54, (a₁= 54) the 2nd term a₂ = 24, then
(a₂ = a₁.r) or 36 = 54.r → r= 36/54 = 2/3. Same logique for the 3rd term. 
So 2/3 is common ratio. We know that :U(n) = a.(r)ⁿ⁻¹. Then if a =54 and r = x (given by the problem), then f(x) = 54.xⁿ⁻¹
n, being the rank of any element of this geometric progression

Can somone explain pythagorous
AleksAgata [21]

Answer:

x=6

Step-by-step explanation:

Pythagorean Theorem: AC^2+BC^2=AB^2

BC= x

AB= 10 cm

AC= 8 cm

~

Now, Substitute

8^2+x^2=10^2

64+x^2=100

100-64=x

\sqrt{36}=x^2

Square root x^2= x, √(36)=6

x=6

Therefore, the length of x = 6

~
