Answer:
c.
Step-by-step explanation:
Answer:
Slope: -10
Y-intercept: 50
X-intercept: 5
Step-by-step explanation:
y-mx+b
y=-10x+50
- m is slope so, slope is -10
- plug in 0 for x and solve to get y-intercept y=-10(0)+50 , y intercept is 50
- plug in 0 for y and solve to get x-intercept 0=-10x+50, x-intercept is 5
In general, to find the surface area of a prism (a shape with 2 bases) is
Area of Base*2 + Lateral Area (Lateral area = Perimeter of bases * height)
#9 Area of base= 2×1÷2=1 *2=2
Lateral area= 2+1+2.2=5.2 5.2*3=15.6
Answer=17.6
#10 Area of Base= 120*2=240
Lateral Area=500
Answer=740
#11
Area of base=8*2=16
Lateral Area= 41.4
Answer=57.4
