A ball is dropped from a height of 64 feet. Its height, in feet, can be modeled by the function h(t) = -16t2 + 64, where t is the time in seconds since the ball was dropped. A. After how many seconds will the ball hit the ground? B. What is a reasonable domain and range for this function?
Answer:
See solution below
Step-by-step explanation:
The ball will hit the ground at whrn t = 0
Given the height of the ball modeled by the expression
h(t) = -16t^2 + 64
0 = -16t^2 + 64
16t^2 = 64
t^2 = 64/16
t^2 = 4
t = 2sec
The ball will hit the ground 2secs after
The domain are the values of the input values t and this values start from 2 and greater. Hence the domain of the function is {2, ∞}
when t = 2
h (2) = -16(2)^2 + 64
h(2) = -64+64
h(2) = 0
Hence the range are the output values i.e the height.
The range are within the range {0, ∞}
solve for c

The cost of 4 tacos is $6.00.
What would be the cost for 10 tacos?
I need help answering this.
Answer:
$15.00
Step-by-step explanation:
To first answer; this we would need to figure out the cost of one taco
Since there are already 4 we would need to divide the price by the amount so you would do
6.00/4=1.5
And now that we have the price of one we can multiply it by 10
1.5*10=15
Can I please have brainliest :)
Answer:
$15.00
Step-by-step explanation:
Each taco is 6/4 = 1.50 so 10 tacos are $15.00

Jodi's best score on a video game is 50 points. Mark's best score on the game is 1.5 times as much as Jodi's best score. How many points did Mark score on the video game? Mark's best score on the game is points. Virginia's best score is only 0.3 times Jodi's best score. How many points did Virginia score on the game? Virginia's best score is points.
Answer:
a) Mark's best score on the game is 75 points.
b) Virginia's best score is 15 points.
Step-by-step explanation:
Jodi's best score on a video game is 50 points.
a) Mark's best score on the game is 1.5 times as much as Jodi's best score. How many points did Mark score on the video game?
Mark's best score on the game is calculated as:
1.5 times as much as Jodi.
Jodi's best score = 50 points
= 1.5 × 50 points
= 75 points
b) Virginia's best score is only 0.3 times Jodi's best score. How many points did Virginia score on the game? Virginia's best score is points.
Virginia's best score on the game is calculated as:
0.3 times as much as Jodi.
Jodi's best score = 50 points
= 0.3 × 50 points
= 15 points
Virginia's best score is 15 points.

Step-by-step explanation:
Just input the first 4 values for x:
(0, y)
y = 4x
y = 4(0)
y = 0
(1, y)
y = 4x
y = 4(1)
y = 4
(2, y)
y = 4x
y = 4(2)
y = 8

Answer:
Step-by-step explanation:
Jarred drew the model below of his backyard. The perimeter of the backyard is 40 feet, and the backyard is 8 feet wide.
his backyard is in rectangle shape and breadth =8
perimeter = 40
but perimeter = 2(l+b)
so
2(l+8)=40
l+8=20
l=12 feet

measure of arc EBC =
9514 1404 393
Answer:
∠BCA = 30°∠FHC = 125°∠A = 45°∠GBC = 75°arc EBC = 260°Step-by-step explanation:
Angle BCA intercepts arc FB, so is half its measure: 60°/2 = 30°.
Angle FHC is half the sum of the angles intercepted by its chords: (60°+150°+40°)/2 = 125°.
Angle A is half the difference of the arcs it intersects: (150° -60°)/2 = 45°.
Angle GBC is half the measure of the arc it intercepts: 150°/2 = 75°.
arc EBC is the sum of arcs EF, FB, and BC: 50° +60° +150° = 260°.

When each operation described below is performed to both sides of an inequality, is the inequality sign preserved or reversed? Operations: preserved: or reversed: Add 3 Subtract -3 Multiply by 3 Divide by -3
Answer:
Add 3 -> Preserve
Subtract -3 -> Preserve
Multiply by 3 -> Preserve
Divide by -3 -> Reverse
Step-by-step explanation:
Required
When is an inequality reversed or preserved
There are only two operations that can reverse an inequality, and they are:
Multiplying the inequality by a negative numberDividing the inequality by a negative numberOther operations will preserve the inequality.
So, the solution is as follows:
Add 3 -> Preserve
Subtract -3 -> Preserve
Multiply by 3 -> Preserve
Divide by -3 -> Reverse
