How do i find the slope

Mathematics
1 answer:
rusak2 [61]2 years ago
6 0
Use the slope formula: y2-y1 over x2-x1 with two coordinate pairs that are shown on the graph.
(12,40)
(8,80)
If you substitute the coordinates in the formula; x1= 12, y1- 40, 8 = x2, 80 = y2
The slope will be -10.
I think. Hope that helped.

4. Divide z(5z2 - 80) by 5z (z+4)​
insens350 [35]

Answer:

z-4

Step-by-step explanation:

z(5z²-80) ÷ 5z(z+4) = z-4

Step-by-step explanation:

Given: z(5z²-80) ÷ 5z(z+4)

Calculation:

First we factor numerator z(5z²-80)

Take out 5 from 5z²-80 and we get 5z(z²-16)

Now we factor 16 = 4²

5z(z²-4²)

Using formula, (a²- b²)=(a+b)(a-b)

5z(z²- 4²)⇒5z(z+4)(z-4)

Simplified fraction

5z(z+4)(z-4) ÷ 5z(z+4)

Cancel like factor from numerator and denominator

⇒ z-4

Thus, z(5z²-80) ÷ 5z(z+4) = z-4

Find the surface area of the figure. Round the the nearest hundredth.
Georgia [21]

Answer:

Step-by-step explanation:

surface area of cylinder=2πrh

SA=1/2×2×π×3×25+2 ×(1/2×π×3²)=75π+9π=84π≈84×3.14≈263.76 cm²

if lowerside is also counted  then area of lower side=25×6=150

total surface area=263.76+150=413.76 cm²

if we take π=22/7

84 π=84×22/7=12×22=264 cm²

if base is also counted then area=264+150=414 cm²
