Hi there
All you have to do is replace a by 2 and b by 7 and solve it.
4(2)^4 - 2(7^2) + 40
4(16)-2(49)+40
64 - 98 + 40
-34 + 40
= 6
Answer : A
Good luck!
Answer:
The area of circle is 706.95 cm²
Step-by-step explanation:
For a given Circle,
Diameter (d) = 30 cm
Radius (r) = ³⁰/₂ = 15 cm
π = 3.142
Now,
Area of Circle
<h3>
<u>Formula</u><u>:</u></h3>
<u>A</u><u> </u><u>=</u><u> </u><u>πr</u><u>²</u>
A = 3.142 × (15)²
A = 3.142 × 15 × 15
A = 706.95 cm²
Thus, The area of circle is 706.95 cm²

Answer:
x = 2
Step-by-step explanation:
<span>F = 755N, and h = 10.0 m and a = 9.8 m/s^2 and m =? and v = ?To find the mass use F = ma 755 = (m)(9.8) and m = .77 kg then use the formula KE + PE = PE2 + KE2 which is 1/2mv2 + mgh = mgh(2) + 1/2mv2 (2) to solve for the velocity. v1 = 0 and h1 = 10 and v2 = ? and h2 = 0 (1/2)(.77)(0^2) + (.77)(9.8.)(10) = (1/2)(.77)(V2^2) + (.77)(9.8)(0)<span>v=14 m/s</span></span>
