Suppose that the height s of a ball (in feet) at time t (in seconds) is given by the formula s(t) = 64 - 16(t - 1)^2. This funct

ion is graphed below on the interval 0 ≤ t ≤ 3. Which labeled point (A-G) corresponds to the release of the ball? How high (in feet) was the ball when it was released? Which labeled point corresponds to the highest point of the ball? When (in seconds after being released) did the ball reach its highest point? Which labeled point corresponds to the ball hitting the ground? How long (in seconds) after being released did the ball hit the ground?

Answer:

Kindly check explanation

Step-by-step explanation:

Suppose that the height s of a ball (in feet) at time t (in seconds) is given by the formula

s(t) = 64 - 16(t - 1)^2

t interval = 0 ≤ t ≤ 3

1) point A (from the graph)

11) Height of ball when it was released

Ball was released at t = 0

s(0) = 64 - 16(0 - 1)^2

= 64 - 16(-1)^2

= 64 - 16(1)

= 64 - 16

= 48 feets

111) point C ( from the graph)

IV) highest point of the ball is 64

Hence,

s(t) = 64 - 16(t - 1)^2

64= 64 - 16(t - 1)^2

16(t - 1)^2 = 64 - 64

16(t - 1)^2 = 0

16t^2 - 32t + 16 = 0

t^2 - 2t + 1 = 0

(t-1) = 0 (t-1) = 0

t = 1

V) Point G (from graph)

V1)

height = 0

s(t) = 64 - 16(t - 1)^2

0 = 64 - 16(t - 1)^2

16(t - 1)^2 = 64

(t - 1)^2 = 64/16

(t - 1)^2 = 4

(t - 1)² = 2²

t - 1 = 2

t = 2 + 1

t = 3

Show your work for -4x+3(2x-5)=31
mina [271]

Step-by-step explanation:

- 4x + 3(2x - 5) = 31 \\  - 4x + 6x - 15 = 31 \\ 2x - 15 = 31 \\ 2x = 31 + 15 \\ 2x = 46 \\ x = 46 \div 2 \\ x = 23

Current research indicates that the distribution of the life expectancies of a certain protozoan is normal with a mean of 46 day
AysviL [449]

Answer: P(x ≥ 47) = 0.25

Step-by-step explanation:

Since the distribution of the life expectancies of a certain protozoan is normal, we would apply the formula for normal distribution which is expressed as

z = (x - µ)/σ

Where

x = life expectancies of the certain protozoan.

µ = mean

σ = standard deviation

n = number of samples

From the information given,

µ = 46 days

σ = 10.5 days

n = 49

The probability that a simple random sample of 49 protozoa will have a mean life expectancy of 47 or more days is expressed as

P(x ≥ 47) = 1 - P(x < 47)

For x = 47

z = (47 - 46)/(10.5/√49) = 0.67

Looking at the normal distribution table, the probability corresponding to the z score is 0.0.75

P(x ≥ 47) = 1 - 0.75 = 0.25

Graph the quadratic function by transforming the graph of f(x) = x^2. Give the minimum or maximum
viktelen [127]

Answer: the maximum is (-2,5 )and the equation for the axis of symmetry is  x = -2

Explanation if you want:

for the min and max:  when a quadratic has a maximum point, that is the largest point that it will ever be at.  When it has a minimum, that is the smallest.

  • the +5 tells us that we have an upward movement of 5. The +2 means we actually move to the point -2.  bc: (x+2)=0 = -2
  • so, from our initial function, those are the changes.

for the axis of symmetry: basically, this is the line that splits the graph into two equal parts.

  • it is the line that goes through the vertex (which we already know is (-2,5).

there u go
