Solve (x-4)² = 5.<br> A. x=9 and x = -1<br> B. x=-4± √√5<br> OC. x=4+√5<br> D. x-5± √√4
dem82 [27]

Answer:

see explanation

Step-by-step explanation:

(x - 4)² = 5 ( take square root of both sides )

x - 4 = ± \sqrt{5} ( add 4 to both sides )

x = 4 ± \sqrt{5}

that is

x = 4 - \sqrt{5} , x = 4 + \sqrt{5}

A rectangular fish aquarium measures 14 in x 24 in x 12 in. If the tank is half full how much more water (in cubic inches) needs
Travka [436]

Answer:

2016in^3 more water is needed.

Step-by-step explanation:

Take the three sides and multiply them together

14in*24in*12in=4032in^3

Since only have the tank is full divide your answer by 2

Write the equation for the perpendicular bisector of the given line segment.
spayn [35]

Answer:

C

Step-by-step explanation:

find the equation of the segment  two point (-5,5) and (-2,-4)

m=y2-y1/x2-x1 =5-(-4)/-5-(-2) =9/-3 = -3

find b : y= -3x+b

            5 =-3(-5) +b

            b=-10

the equation is : y=-3x-10

the perpendicular line is y=1/3 x -2/3

Find all x-intercepts and y-intercepts of the graph of the function.<br> F(x)=x³-4x² - 4x + 16
Lady bird [3.3K]

Answer: (0;16)  (4;0)  (2;0)  (-2;0).

Step-by-step explanation:

Y-intercepts of the graph of the function F(x)=x³-4x² - 4x + 16:

x=0\\F(x)=0^3-4*0^2-4*0+16\\F(x)=16.\\Hence,\  (0;16).

X-intercepts of the graph of the function F(x)=x³-4x² - 4x + 16:

F(x)=0\\0=x^3-4x^2-4x+16\\0=(x^3-4x^2)-(4x+16)\\0=x^2*(x-4)-4*(x-4)\\0=(x-4)*(x^2-4)\\0=(x-4)*(x^2-2^2)\\0=(x-4)*(x-2)*(x+2)\\x-4=0\\x_1=4.\\Hence,\ (4;0)\\x-2=0\\x_2=2.\\Hence,\ (2;0)\\x+2=0\\x_3=-2.\\Hence,\ (-2;0).
