Each equation must be increasing or decreasing by a constant amount in order for it to be linear. Graphing these equations, you can see that the linear equations will be a straight line.
Answer:
65449.8 cm3
Step-by-step explanation:
We start with the volume formula for a sphere: 4/3 πr3
We start with subbing in 25 to r, then we cube 25, which is equal to 15625.
We multiply 4/3 and pi. And lastly we multiply what we got by 15625 and either round the answer or fphaving fixed your calculator.

Step-by-step explanation:
Equation of a circle:
The equation of a circle with center 
and radius r is given by:
Center: (−2, −5); radius= 1
This means that 
. So
This is the equation of the circle.
Answer:
<h2>m∠LMN = 26°</h2>
Step-by-step explanation:
Since ∠LMN and ∠PQR are complementary it means that the sum of their angles is 90°
To find m∠LMN , add both m∠LMN and m∠PQR and equate it to 90 to find x then substitute the value of x into the expression for m∠LMN
That's
m∠LMN + m∠PQR = 90
4x - 2 + 9x + 1 = 90
13x - 1 = 90
13x = 90 + 1
13x = 91
Divide both sides by 13
x = 7
From the question
m∠LMN = (4x-2)
m∠LMN = 4(7) - 2 = 28 - 2
We have the final answer as
<h3>m∠LMN = 26°</h3>
Hope this helps you
Answer:
B / 452.4 cubic inches
Step-by-step explanation:
The equation to find the volume of a cylinder is<em> V = πr²h, </em>where r is the radius and h is the height. The height of the cylinder in this image is 16 inches and the radius of the cylinder is 3 so if you plug those numbers into the equation, it would look like V = π3²16 and if you simplify it, it turns into V = 452.38, which when round to the nearest tenth, is 452.4 cubic inches.
