Answer:
well, we do not have the options here, but we can find the equation of the graph, so the equations that are different from that are the answer to this question:
in the graph, we can see that it goes through the points:
(0,1) and (2,0)
Remember that the slope of a line that goes through the points (x1, y1) and (x2, y2) is:
s = (y2 - y1)/(x2- x1)
then the slope for our line is:
s = (0 - 1)/(2 -0) = -1/2
Then our line is:
y = -(1/2)*x + b.
b is the y-intercept, and we know that when x = 0 y = 1, then:
1 = -(1/2)*0 + b
1 = b
then the equation is:
y = -(1/2)*x + 1
Answer:
2
Step-by-step explanation:
(1-5)/(-3+1) = -4/-2 = 2
Answer:
15/2 in³
Step-by-step explanation:
The formula for the vol. of a pyramid
is
V = (1/3)(area of base)(height of pyramid)
Here, the volume is:
V = (1/3)( [1/2][5 in][9 in] )·(10 in)
= (9/3)(5/2)(10) in³
= 450/6 in³ = 150/2 in³ = 75 in³ Volume of the pyramid
Answer:
√23/√45 or √23/3√5
Step-by-step explanation:
Cosine is adjacent over hypotenuse. Angle W has an adjacent side of WU(√23) and WV .You know the adjacent but not the hypotenuse, so you will use the formula a^2+b^2=c^2 to find the hypotenuse. Plug in the sides for A and B -> (√23)^2+(√22)^2=c^2. Simplify it --> 23+22=c^2 --> 45=c^2. Solve for C alone (not c^2). √45=c. Then use the cosine formula (adjacent/hypotenuse) to plug in the numbers.
