Answer:
The velocity after time t=7s. is 32 feet/s
Step-by-step explanation:
Given equation is v=(-32)t+256.
Where, v is velocity in feet/sec and t is time in seconds.
The figure show that graph of equation.
To find velocity after time t=7s.
Step 1 : Draw a graph of equation with time on x-axis and velocity of y-axis.
Step 2: Draw a line t=7and extent until it intersects with the equation of line.
Step 3: From point of intersection, draw a line parallel to x-axis and let it intersect the y-axis.
Wherever the line intersect with y-axis is answer for velocity after time t=7s.
From the figure,
The velocity after time t=7s. is 32 feet/s
<em>Verification,</em>
v=(-32)t+256.
When t=7s
v=(-32)(7)+256.
v=32feet/s
Answer: true
Step-by-step explanation:
since the triangles are similar the sides are proportional
Answer:
v — Prove that (ax + b)/(cx + d) is irrational if and only if ad = bc. ... If b = 0, we have (ax + b)/(cx + d) = 0 is rational; if c = 0, since ... nonzero integers m, n ∈ Z. Then we have ... Proof. We prove by induction. When n = 1, both sides are 1/2 hence the ... So there are less than (k + 1)(2k + 1)k+1 (actually muc

Answer:
30% probability a randomly selected household has no Internet access given the household owns corporate stock
Step-by-step explanation:
I am going to say that we have two events.
Event A: Owning corporate stock. So P(A) = 0.54.
Event B: Having no internet access. So P(B) = 0.3.
Since they are independent events, we can apply the conditional probability formula, which is:
In which
P(B|A) is the probabilitty of event B happening given that A happened. We want to find this.
is the probability of both events happening.
Since they are independent
So
30% probability a randomly selected household has no Internet access given the household owns corporate stock
