y=2x−1. Explanation: the equation of a line in slope-intercept form is. ∙xy=mx+b. where m is the slope and b the y-intercept. here m=2. ⇒y=2x+b←is the partial equation. to find b ...
Answer:
Step-by-step explanation:
First find the surface area of the clyinder and find the area circles and subtract
Then find the surface area of a cone, remove the circle area and double it.
Clyinder surface area (without circle area) 2πrh+2πr2=2·π·4·6+2·π·42≈251.32741
251.32741 - 50.2 - 50.2
Cone area: A=πr(r+h2+r2)=π·4·(4+32+42)≈113.09734
113.09734 - 50.2 - 50.2
Total: 12.69734 + 150.92741 = 163.62475
P(x) = 25^2 -24x + 615
P(8) = 25(8 squared) -24(8) +615 = 2023
Answer:
-3 < x
Step-by-step explanation:
15 > -5x
Divide each side by -5, remembering to flip the inequality since we are dividing by a negative
15/-5 < -5x/-5
-3 < x
