Answer:
A =12.56 m^2
Step-by-step explanation:
Find the area of a circle with radius 4
A = pi r^2
A = 3.14 * 4^2
A =50.24
Since this is 1/4 of the circle, multiply by 1/4
A = 1/4 * 50.24
A =12.56 m^2
Answer:
m = undef
General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
<u>Algebra I</u>
- Slope Formula:

Step-by-step explanation:
<u>Step 1: Define</u>
Point (3, -2)
Point (3, 6)
<u>Step 2: Find slope </u><em><u>m</u></em>
- Substitute:

- Add/Subtract:

- Divide: m = undef
When we divide anything by zero, we will get undefined. Therefore, this would be a vertical line.
The correct equation that represents the expression "The number 24 is what percent of the number 40?" is as shown below;
The the unknown number in percent be 'x'
x percent of number 40 is expressed as;
x% of 40
x/100 of 40
If 24 is equal to the expression above, then the final equation will be expressed as;
24 = x/100 of 40
24 = 40x/100
24 = 0.4x
Rearrange
0.4x = 24
Hence the correct equation used to solve the problem is 0.4x = 24
Hello : let h =f(t)
<span>the ball hit the ground if : f(t) =0
solve : </span><span> -16t² + 20t + 6=0
</span><span>Δ = b²-4ac ... a = -16 b= 20 c =6
</span>Δ =(20)²-4(-16)(6) = 784 = 28²
t1 = (-20-28)/-32 = 48/32 =3/2
t2 =(-20+28) /-32 <span>< 0 refused
conclusion : t=3/2</span>
