A. The answer is 494.6 rounded.
b. She most likely did not add 417.62 to 76.9
Answer:
f(x) = 16x2 + 32x - 9
To find the "zeros", set f(x) = 0:
0 = 16x2 + 32x - 9
The equation is solvable by factoring or by using the quadratic formula. The factors (use the "ac" method) are:
0 = (4x-1)(4x+9)
x = 1/4 = 0.25 and x = -9/4 = -2.25
Step-by-step explanation:
<span><span><span><span>3/4</span>x</span>+11 </span>< <span><span>0.3x</span>+<span>3/4
</span></span></span>First turn 3/4 from both sides to decimals to get..
.75x+11 < 0.3x+.75
And then subtract 0.3x from both sides to get
.45x+11 < .75
And then subtract 11 from both sides to get
.45x < -10.25
And then divide both sides by .45x to get
x < -22.77777778
Answer: 7.29π mm²
Step-by-step explanation:
First, I am assuming XY is the diameter of the circle :)
The formula for the area of a circle is πr² (r = radius)
So that means we need to divide the diameter by 2 to find the radius
5.4 / 2 = 2.7
Now we simply plug in our numbers!
3.14 · 2.7²
3.14 · 7.29
And that's it!
Hope this helped you :)
