Step-by-step explanation:
Answer:
18. 2,047.5 yd³
19. 3204 in.²
Step-by-step explanation:
18. Volume of triangular prism = triangular base area × height of prism
Height of prism = 21 yd
Triangular base area = ½*b*h
b = 15 yd
h = √(15² - 7.5²) = √168.75 ≈ 13 yd
Triangular base area = ½*15*13 = 97.5 yd²
Plug in the values into the formula of the volume of prism
Volume of prism = 97.5 × 21
= 2,047.5 yd³
19. Surface area = 2πrh + 2πr²
Where,
r = 15 in.
h = 19 in.
Plug in the values
Surface area = 2*π*15*19 + 2*π*15²
Surface area = 3204.42 ≈ 3204 in.² (nearest whole number)
You are given
two points, (-1, 10) and (5, 8). You are required to find the equation in slope
intercept form given the points. The equation of a slope intercept form is y =
mx + b. Where m is the slope and b is the y-intercept. By definition, slope, m,
is the rise over run or the difference of y over the difference of x.
m =
y2-y1/x2-x1
Let us denote
y2=8, y1=10, x2=5 and x1=-1 and we get
m =
8-10/5-(-1)
<span><u>m = -1/3</u>,
a negative slope means it is rising to the left of the graph.</span>
Since the
slope passes the two points, it also passes the y-intercept. Choose one of the
points, (-1, 10) and substitute it to y = mx + b.
y = mx + b
10 =
(-1/3)(-1) + b
<u>b = 29/3</u>
<u>The
equation now is y = -1/3x + 29/3.</u>
