If you take the square root of 9, it's 3
if you take the square root if 16, it's 4
I would guess it to be about 3.2
Answer:
Step-by-step explanation:
Lily , we know that [tex]3^{2}[/tex] =9 and [tex]4^{2}[/tex] = 16 so we know that [tex]x^{2}[/tex] = 10 , where 10 is an answer to x squared, then X lies between 3 and 4 , see?
Select all correct ways of factoring –3x – 9.
Answer:
Some possible expressions, since there's no answer choices provided:
-3(x + 3)
3(-x - 3)
Step-by-step explanation:
Expression 1:
This uses a GCF of -3, since -3x and -9 are divisible by this. Let's divide -3x and -9 by this first:
-3x / -3 = x
-9 / -3 = 3
So now, we can add these terms and multiply them by -3 to get our answer:
-3(x + 3)
And just to check, we can expand it:
-3x + -3(3) = -3x - 9
Expression 2:
This uses a GCF of 3, like the last one but it's negative. -3x and -9 are also divisible by this. Let's divide both terms by this GCF first:
-3x / 3 = -x
-9 / 3 = -3
Now, we can add these terms and multiply them by -3 to get our final answer:
3(-x - 3)
To check, once again:
-3x + 3(-3) = -3x - 9

A girl throws a paper airplane from her treehouse. The height of the plane is a function of time and can be modeled by the equation ℎ()=25+2.5−122. Height is measured in feet and time is measured in seconds.
h(0) show the initial height of the plane, that is 25 feet.
The given equation is h(t)=25+2.5t-1/2 t².
Here, h(0)=25+2.5(0)-1/2 (0)²
h(0)=25
This shows the initial height is 25 feet.
Therefore, h(0) show the initial height of the plane, that is 25 feet.

The measure of the angle of the triangle is calculated by the law of sines and m∠S = 59.7°
What is the law of sines?The relationship between a triangle's sides and angles is provided by the Law of Sines. Trigonometry's law of sines can be expressed as a/sinA = b/sinB = c/sinC, where a, b, and c are the lengths of the triangle's sides, and A, B, and C are the triangle's respective opposite angles.
Law of Sines :
a / sin A = b / sin B = c / sin C
Given data ,
Let the triangle be represented as ΔRST
Now , the measure of s = 620 cm
The measure of side r = 210 cm
And , the measure of angle m∠R = 17°
From the law of sines , we get
a / sin A = b / sin B
On simplifying , we get
sin ( 17 )° / 210 = sin ( S ) / 620
Multiply by 620 on both sides , we get
sin ( S ) = ( 620 / 210 ) x 0.2923717
On further simplification , we get
sin S = 0.86319265203
Taking inverse on both sides , we get
S = sin⁻¹ ( 0.86319265203 )
S = 59.68°
S = 59.7°
Therefore , the value of S is 59.7°
Hence , the measure of angle m∠S = 59.7°

What is the height of a cone that has a volume of 90m³ and has a radius of 3.5 m?
The answer is 7.02.
This is because pi×r^2×h/3
h=3 90/3.14×3.5^2=7.01581m
Answer:
h = 7.02 m
Step-by-step explanation:
Volume of a cone = ⅓ × πr²h
h = 3 × V/πr²
= 3 × 90/3.14×(3.5)²
≈ 7.015.. m
≈ 7.02 m

The volume of a cylinder is 720π cm3. The height of the cylinder is 20 cm. What is the radius of the cylinder?
Answer:
Radius = 3.38 cm
Step-by-step explanation:
Here's your solution
=> The volume of cylinder = 720π cm^3
=> The height of cylinder = 20 cm
=> Radius = ?
=> Formula of volume of cylinder = πr^2h
=> 22/7 * r^2 * 20 = 720π cm^3
=> r^2 = (720*7)/20*22
=> r^2 = 11.45
=> r = √11.45
=> r = 3.38 cm
