Answer:
C) y = 2x + 3
Step-by-step explanation: You have to substitute 1 for x & 5 for y & 2 for m, but 1st do the point slope form ---> slope intercept form.
y -Y1 = m(x - X1)
y - 5 = 2(x - 1)
y - 5 = 2x - 2
+5 + 5
y = 2x + 3 --- IN SLOPE INTERCEPT FORM
Hope this helps you!!! :)
Answer:
Step-by-step explanation:
<h2>A rocket is launched from a tower. The height of the rocket, y in feet, is related to the time after launch, x in seconds, by the given equation. Using this equation, find the time that the rocket will hit the ground, to the nearest 100th of second.
</h2><h2>y=-16x^2+129x+119
</h2><h2>y=−16x </h2><h2>2
</h2>
+129x+119
Using the
solver function of the calculator, we can find the roots of the polynomial.
x1
= 9.72484
x2 = −5.36242+8.74882i
x3 = −5.36242−8.74882i

Since
dimension cannot be imaginary, therefore the height of the cylindrical hole is
9.72 mm.
Calculating
for radius r:
r
= 9.72 mm – 8 mm
r
= 1.72 mm
The
volume of cylinder is given as:
V
= π r^2 h
V
= π (1.72)^2 (9.72)
<span>V
= 90.34 mm^3</span></span>
