It's a quadratic equation. Solve it through factorisation.
5s^2 - 14s - 3 = 0
(5s + 1)(s - 3) = 0
5s + 1 = 0
or
s - 3 = 0
Therefore
s = -1/5
or
s = 3
Answer:
3200
Step-by-step explanation:
growth = current population + rate * time
= 2000 * .04 * 15
= 1200
original population + growth = total
2000 + 1200 = 3200

- <em><u>A. Draw a diameter of the circle. </u></em>
Explanation:
To<em> draw a square</em> you can <em>draw a circle</em> with a <em>compass</em> and then construct the inscribed square.
You can construct an inscribed square with a compass and a straightedge.
The <u>first step</u> is to draw the circle.
The <u>next</u> step is to <em>draw a diameter</em> (any line that passes through the center of the circle, which you marked when drew the circle). Hence, this is the correct answer to the queston, and it is described by the choice A.
After that, you will be able to draw the perpendicular bisector of the diameter. The two diameters drawn will mark four equidistant points on the circle which will be the four vertices of your square.
Finally, you just must join the adjacent vertices with the straightedge.
Step-by-step explanation:
|4x + 8| > 2
Therefore 4x + 8 > 2 or 4x + 8 < -2.
When 4x + 8 > 2, 4x > -6, x > -1.5.
When 4x + 8 < -2, 4x < -10, x < -2.5.
Hence, x < -2.5 or x > -1.5.
Answer:
20mph
Step-by-step explanation:
because when you divide the 280 it goes by 20 mph to get to 280 miles by quarters but in 20s
