a bowling ball is dropped from a height of 24 feet. write a function that gives the height h (in feet) of the bowling ball after t seconds

Answers

Answer 1
gravity pulls at 32 feet per second so it would take .75sec to hit the ground now make an equation that can make this applicable so after .75 second T it would be at 0 feet H
Answer 2

Answer:

[tex]h=16t^2[/tex]

Step-by-step explanation:

t = Time taken

u = Initial velocity

v = Final velocity

s = Displacement

a = Acceleration due to gravity = 32 ft/s²

[tex]s=ut+\frac{1}{2}at^2\\\Rightarrow h=ut+\frac{1}{2}32\times t^2\\\Rightarrow h=ut+16t^2[/tex]

Here, u = 0 so,

[tex]h=0t+16t^2\\\Rightarrow h=16t^2[/tex]

The equation is [tex]h=16t^2[/tex]

[tex]24=16t^2\\\Rightarrow t=\sqrt{\frac{24}{16}}\\\Rightarrow t=1.22\ s[/tex]

Time taken by the ball to hit the ground is 1.22 seconds

What is the Pythagorean theorem?

Pythagorean theorem states that in the right angle triangle, the hypotenuse square is equal to the square of the sum of the other two sides. According to this statement, the areas of the squares on the other two sides add up to the size of the square whose side is the hypotenuse.

Use the Pythagorean theorem to calculate the length of AB as below,

OB² = AB² + OA²

(BC + OC)² = AB² + OA²

(27 + 24)² =  AB² + 24²

AB² = 51² - 24²

AB = 45 units

Therefore, the correct option is A. The value of length AB is 45.

Deshaun went for a drive in his new car. He drove at a speed of 62 miles per hour for 99.2 miles. For how many hours did he drive?

Answers

62/1  99.2/x 
99.2/62 = x
The answer is 1.6 hours.

Deshaun drove at a speed of 62 miles per hour for 99.2 miles. To calculate the time spent driving, use the formula Time = Distance / Speed. The time taken for his drive is approximately 1.6 hours.

The question pertains to calculating the driving time given the speed and distance traveled by Deshaun in his new car. He drove at a speed of 62 miles per hour for 99.2 miles. To find out how many hours he drove, we use the formula for time which is:

Time (t) = Distance (d) / Speed (v)

Here, the distance d is 99.2 miles and the speed v is 62 miles per hour.

So we calculate the time t as follows:

t = 99.2 miles / 62 miles per hour

The time taken by Deshaun for his drive is approximately 1.6 hours.

A boat, whose speed in still water is 1.96 m/s, must cross a W = 217 m wide river and arrive at a point D = 111 m upstream from where it starts, as shown in figure below.

Answers

if u resolve the inital velocity then u will get the vertical component to be 1.96*cos 42.9 = 0.732 * 1.96=1.434 m / s time taken to cross = 217 / 1.434=151.32seconds distance travelled in x direction = 111m initial velocity in x direction = - 1.96 * sin 42.9 = = -0.680 *1.96= - 1.33 disance = speed * time d = (v of current + velocity of man) * time 111= (v - 1.33)* 151.32 v - 1.33 = 0.733 v= 1.33 + 0.73 = 2.063

eremy is working at 2 jobs to save money for his college education. He makes $8 per hours working for his uncle at Pizza Pie busing tables and $10 per hour tutoring peers after school in math. His goal is to make $160 per week. Part c- After researching the costs of colleges, Jeremy decides he needs to make more than $160 each week. Write an inequality in two variables to represent the amount of money Jeremy needs to make. Then graph.

Answers

If "p" is the number of hours Jeremy works at Pizza Pie, then 8p is the number of dollars he makes from Pizza Pie. In the same way, if "m" is the number of hours he spends tutoring math, then 10m is the amount of money he makes from tutoring math. Together, he makes 8p + 10m dollars each week. But Jeremy needs that amount of money to be MORE than $160. So that becomes the inequality... 8p + 10m > 160 You can graph it by using "m" as one axis and "p" as the other.

Final answer:

Jeremy needs to create an inequality to represent his new earning goal higher than $160 a week, leading to the inequality 8x + 10y > 160. This can be graphed by first converting to intercept form, plotting the intercept and slope, drawing a dashed boundary line, and shading the region above this line.

Explanation:

Jeremy is working two jobs to save for his college education and needs to create an inequality to represent the amount he needs to make each week, now more than $160. Let's denote the number of hours Jeremy works busing tables as x and the number of hours he spends tutoring as y. He makes $8 per hour busing tables and $10 per hour tutoring.

To express Jeremy's goal of making more than $160 a week, we can write the following inequality:

8x + 10y > 160

To graph this inequality:

First, rewrite the inequality as y > (-4/5)x + 16 to get the intercept form.

Plot the y-intercept at (0, 16) on the graph.

Use the slope of -4/5 to determine another point. From (0, 16), move 5 units to the right (positive x-direction) and 4 units down (negative y-direction), then plot this second point.

Draw a dashed line through the two points to represent the boundary of the inequality (dashed because the inequality is strict and does not include the line itself).

Shade above the line to indicate that all solutions to the inequality lie in this area, where Jeremy would be earning more than $160.

D. The graph of ƒ(x)=-1/2√x will look like the graph of ƒ(x)=√x but will shrink it vertically by a factor of 1/2.
...?

Answers

Answer:

A

C

Step-by-step explanation:

Here we must compare a function and its transformation, we will see that the correct options are A and C.

First, we must define the transformations that we will be using here.

Reflection about the x-axis:

For a function f(x) a reflection about the x-axis is written as:

g(x) = -f(x)

Vertical contraction.

For a function f(x) a vertical contraction of scale factor k is written as:

g(x) = k*f(x)

So here we start with:

ƒ(x)=√x

Then we reflect it about the x-axis to get:

ƒ(x)=-√x

Then we shrink it by a scale factor k = 1/2

ƒ(x) = (-1/2)*√x

From this, we can see that the correct options are:

A. The graph of ƒ(x)=-1/2√x will look like the graph of ƒ(x)=√x but will reflect it about the x-axis and shrink it vertically by a factor of 1/2.

And C is also true, because we have a reflection about the x-axis, the range changed from positive values to negative values, so:

C. ƒ(x)=-1/2√x has the same domain but a different range as ƒ(x)=√x.

Is also a correct option.

Well to demonstrate the answer, let's look at a basic example:

Sq root of 2^2 = ?
Well 2 ^2 = 2•2 = 4 and the square root of 4 is 2. So whenever you think of what the opposite of squaring or raising something to the value of 2, the reverse would be taking the square root of the number or expression.

So sq root of 14x • sq. root of 14x = (sq. root of 14x) ^2 which is simply 14x.

The solution is 14x.

I'm assuming you don't know the definition of similarity, which is fine, but I want to clarify just in case you don't: Similarity is when two figures are the same in angles ONLY, and their sizes are proportional. Given this, PQR has a side 20" and TUV's respective side is 6". Now, there's a ratio: 20:6 Now, would you agree that it would then be logical that the perimeter would follow the same ratio?

If we set the vertex at (0,0) then the curve goes through (30,30) 

y = 1/30 x^2

The length of a rectangle is 12 inches more than its width. What is the width of the rectangle if the perimeter is 42 inches?

Answers

I hope this helps you
The question is what both experssions best represent in the context of the problem.

The expresssion x best represents the width of the rectangle.

The expression x + 12 best reprents the lenght of the rectangle.

This is because if you call x the width, then the length is 12 more than that, i.e. 12 + x.

If you wanted to solve the problem now you could write

2*(width + length) = perimeter

2(x + 12 + x) = 24 and solve for x.

But the answer to the question is:

x best represents the width of the rectangle.

x + 12 best reprents the lenght of the rectangle.
