9. 1 is the y-in and 5 is the slope.
10. I couldn’t see the side of this one but I hope 9 helped :)
Answer:
Step-by-step explanation:
Use <u>tigonometry</u> to find the value of d
- sine = opposite side / hypotenuse
- 306/d = sin 38°
- d =306/sin 38°
- d = 497 m (rounded)
Answer:
this is a confusing one
Step-by-step explanation:
Slope of a line = (y2-y1)/(x2-x1)
In this problem:
y2= 1
y1= 0
x2=4
x1= 3
m = (y2-y1)/(x2-x1)
m = (1-0)/(4-3)= 1/1= 1
y= mx+b (line equation)
y-intercept occurs when x=0. So, plug in a point to find b.
I used (4,1)
y=mx+b
y= (1)x+b
1=(1)(4)+b
1=4+b
b= -3
Y-intercepts of the x-axis at (0,-3). Y-intercept= -3
Any further questions?
Answer:
Step-by-step explanation:
The rate of change of the radius dr/dt = . 75 in/min because the radius is increasing with respect to time. hence, the volume is increasing at a rate of 75π cu in/min when the radius has a length of 5 inches.
