Answer:

(4 + y)(4 - y)

Step-by-step explanation:

[tex]16 - {y}^{2} \\ \\ = {4}^{2} - {y}^{2} \\ \\ = (4 + y)(4 - y)[/tex]

Answer:

[tex]f(x)=\frac{1}{100} (\frac{1}{2})^{x}[/tex]

Step-by-step explanation:

[tex]f(x)=ab^{x} \\\\f(0)=\frac{1}{100\\}[/tex]

⇒ [tex]a=\frac{1}{100} \\\\f(1)=\frac{1}{200}\\ \\a.b=\frac{1}{200} \\\\[/tex]

⇒[tex]\frac{1}{100} .b=\frac{1}{200}[/tex]

⇒b=[tex]\frac{1}{2}[/tex]

⇒[tex]f(x)=\frac{1}{100} (\frac{1}{2})^{x}[/tex]

hope it helps

Answer:

a) 1 atm

b) 2 atm

c) 3 atm

d) f(x) = (1/33)d + 1

Step-by-step explanation:

a) Surface of the water is the same as 0 depth, and the table shows that when there's 0 depth in feet, there is 1 atm of pressure.

b) Table shows when 33 feet deep, there is 2 atm of pressure.

c) Table shows when 6 feet deep, there is 3 atm of pressure.

d) To make a function equation, you need to find the slope and y-intercept.

The slope is (y2-y1)/(x2-x1), which would be (3-2)/(66-33). This would equal 1/33, which is our slope.

The y-intercept would be the y coordinate of where the x coordinate would equal 0, which would be 1 in this case.

Function equation is y = mx + b

m = slope

b = y-intercept

-> y = (1/33)x + 1

There are six sections in the spinner below. There are two vowel sections. Two sixths is the first representation.

1. Turn Two Sixths Into A Decimal.

Answer:

let the the first number X,

second number be 2×(8x) or. 16x

third number be 8x

equation 1 ,

X + 16x + 8x = 84

or. 25x = 84

or. x = 84 ÷ 25 = 3.36

Answer:

2.4 use a scientific calculator like desmos it will really help:)

Step-by-step explanation:

Answer: A

Explanation:

Because the center of circle A is (0,1) and circle B is one unit down, it would be x^2+y^2=1 because the center of circle B is (0,0). (The equation for a circle is (x-h)^2+(y-k)^2=r^2 with h and k as coordinates of the center of the circle and r as the radius.)

Step-by-step explanation:

this triangle is a Right angle triangle so we gonna use Pythagoras theorem to find the unknown side the equation for this Triangle

X^2 +Y^2=R^2

X stand for X values (adjacent) and Y(opposite) sthands for Y values why R stand for hypotenuse side

The circumference of the circle is 55.9 m

The radius is given as 8.9 m

The formula for calculating circumference of a circle is

= 2πr

= 2 × 3.142 × 8.9

= 55.9

Hence the circumference of the circle is 55.9m
