Answer:
z = [tex]\sqrt{10}[/tex]
Step-by-step explanation:
Small triangle:
short leg = 2
long leg = z
Large triangle
short leg = z
long leg = 5
-------------------------
The triangles are similar therefor
Sshort / Lshort = Slong / Llong
2/z = z/5
multiply both sides by z
2 = [tex]z^{2}[/tex]/5
multiply both sides by 5
10 = [tex]z^{2}[/tex]
Take the square root of both sides
z = [tex]\sqrt{10}[/tex]

find x
Answers
Answer:
[tex]x=\sqrt{\dfrac{a(b-y^2)}{b}}[/tex]
Step-by-step explanation:
The given equation is :
[tex]x^2\div a+y^2\div b=1[/tex]
We need to find the value of x.
It can also written as :
[tex]\dfrac{x^2}{a}+\dfrac{y^2}{b}=1[/tex]
Subtract [tex]\dfrac{y^2}{b}[/tex] from both sides,
[tex]\dfrac{x^2}{a}+\dfrac{y^2}{b}-\dfrac{y^2}{b}=1-\dfrac{y^2}{b}\\\\\dfrac{x^2}{a}=\dfrac{b-y^2}{b}\\\\\text{Cross multiplying both sides}\\\\x^2=\dfrac{a(b-y^2)}{b}\\\\x=\sqrt{\dfrac{a(b-y^2)}{b}}[/tex]
Hence, the value of x is equal to [tex]\sqrt{\dfrac{a(b-y^2)}{b}}[/tex].

The highest speed ever recorded for a bicycle was 166.944 miles per hour. What is this speed rounded to the NEAREST tenth?
Answers
Answer:
166.9 miles per hour
Step-by-step explanation:
To round a number to the nearest tenth, look at the next place value to the right (the hundredths). If it's 4 or less, just remove all the digits to the right. If it's 5 or greater, add 1 to the digit in the tenths place, and then remove all the digits to the right. Then, the answer is 166.9.

A flowerpot has a circular base with a diameter of 27 centimeters. Find the circumference of the base of the flowerpot. Round to the nearest tenth.
How would you go about solving this?
Answers
The circumference of the base of the flowerpot is 84.8cm
What is circumference of a circle?Circumference of a circle can be described as the length or distance of a circle.
The formular that can be used to calculate the circumference of a circle is
= 2πr
Radius= diameter/2
= 27/2
= 13.5
The circumference can be calculated as follows
= 2πr
= 2 × 3.142 × 13.5
= 84.83
≅ 84.8 (to the nearest tenth)
Hence the circumference of the base of the flower pot is 84.8 cm

Answers
Answer:
X is a discrete Random variable where X is the number of races Jockey can win.
Step-by-step explanation:
To find - A jockey will ride horses in 10 different races at a race track today.
The number of races that the jockey will win is what type of random variable ?
Proof -
Given that,
A jockey will ride horses in 10 different races at a race track today.
Let us assume that,
X is the number of races Jockey can win
So,
X can take value 0, 1, 2, 3, ......10
As,
It can take countable finite values
So,
X is a discrete Random variable
∴ we get
X is a discrete Random variable where X is the number of races Jockey can win.
