If z^2 is directly proportional to W and Z=4 when W=8

Mathematics

Answer:

z² = 2W

Step-by-step explanation:

Assuming you require the equation of proportionality

Given z² is directly proportional to W then the equation relating them is

z² = kW ← k is the constant of proportion

To find k use the condition z = 4 when W = 8

4² = 8k

16 = 8k ( divide both sides by 8 )

2 = k

z² = 2W ← equation of proportionality

Answer:

The constant of proportionality is 2.

Step-by-step explanation:

z^2 = kW   where k is a constant.

When z = 4 , W = 8 so

4^2 = 8k

k = 4^2/8

= 16/8

= 2.

Answer:

circle question: 69.66

the other question: 66.8

Step-by-step explanation:

For the circle question:

the circle is inscribed in the square, so the diameter of the circle = side of the square

so we need to find the area of square and circle

then do this

square area - circle area

square area(side×side) = 324

circle area(pi×r^2)≈254.469

so shaded region = 69.66

__________

the other question:

we need to find the area of triangle and the area of the rectangle and add them together

A of Triangle (1/2×base×hight) = 34.32

A of rectangle (width × length) = 31.92

add them, so the answer will be = 66.8

Can someone please help? i don’t know how to solve this.
Charra [1.4K]

Answer:

Hey there!

We have the absolute value of x is greater than two.

Thus, to solve absolute value inequalities, we want to break the inequality down.

We break this down to

x>2

x<-2

Thus, we don't need to simplify this any further, and have our answer.

Hope this helps :)
