The area of a parallelogram is 375 centimeters the base is 25 centimeters find the height

Answers

The formula for finding the area of a parallelogram is the base*height.
By plugging in the information that you have already, we know that: 25*height=375
In other words:
25x=375
x=15

The height is 15cm.

To find the answer to the problem "The area of a parallelogram is 375 centimeters the base is 25 centimeters find the height." you must divide the area by the base.
375 divided by 25 equals 15

a volleyball reaches its maximum height of 13 feet, 3 seconds after its served. Which of the following quadratics could model the height of the vollyball over time after it is served. Select all that apply.

A: f(x)=2x^2+12x+5

B: f(x)=-2x^2+12x-5

C: f(x)=-2x^2-12x+5

D: f(x)=-2(x-3)^2+13

E: f(x)=-2(x+3)^2+13

Answers

Only selections B and D give a maximum height of 13 at t=3. However, both of those functions have the height be -5 at t=0, meaning the ball was served from 5 ft below ground. This does not seem like an appropriate model.

We suspect ...
• the "correct" answers are probably B and D
• whoever wrote the problem wasn't paying attention.

Answer:

Step-by-step explanation:

Intuitively it's a volleyball game reaching its maximum height, then we must discard the 1st option because of its parameter a >0, and whenever a>0 the parabola makes a curve, rather different than in a volleyball game.

Also, considering Vertex of this parabola by (-b/2a, -Δ/4a) given the fact that the question says the maximum height.

Taking

y= height in feet

x= time in second

Function Vertex (-b/2a, -Δ/4a)=(-3, -13)

A: f(x)=2x²+12x+5 False

B: f(x)=-2x²+12x-5 Function Vertex (-b/2a, -Δ/4a) = (3,23) False

C: f(x)=-2x²-12x+5 Function Vertex (-b/2a, -Δ/4a) = (-3,23) False

D: f(x)=-2(x-3)²+13 Function Vertex (-b/2a, -Δ/4a) = (3,13) True

E: f(x)=-2(x+3)²+13 Function Vertex (-b/2a, -Δ/4a) =(-3,13) False

Peter is 2 years older than Winnie. Peter's age is 16 years less than seven times Winnie's age. The equations below model the relationship between Peter's Age (p) and Winnie's age (w):

p=w+2
p=7w-16

Which is a possible correct method to find Peter's and Winnie's ages?

A. Solve w+2 = 7w-16 to find the value of w
B. Solve p+2 =7p-16 to find the value of p
C. Write the points where the graphs of the equations intersect the x axis
D. Write the points where the graphs of the equations intersect the y axis

Answers

Given equations:
P=w+2
p=7w-16
Compare both equations
7w-16=w+2
Add 16 to both sides.
7w=w+18
Subtract w from both sides.
6w=18
Divide both sides by 6.
w=3, which is the age of Winnie.
Now Peter's age=3+2=5 years

Option A is the correct method to find the age of Peter and Winnie.

Answer:

A. Solve w+2 = 7w-16 to find the value of w.

Step-by-step explanation:

Here p represents the age of Peter and w represents the age of Winnie,

Given,

Peter is 2 years older than Winnie.

⇒ p = w + 2 -----(1)

Also, Peter's age is 16 years less than seven times Winnie's age.

⇒ p = 7w - 16 -----(2),

By equating right sides of equation (1) and (2),

We get,

w + 2 = 7w - 16,

Since, this equation is only in the variable w,

Thus, we can find the value of w with help of the above equation,

After putting this value in either of equation (1) or (2),

We can find the value of p.

Hence, option A is correct.

Note : From equation (1) and (2),

w = p - 2 and [tex]w=\frac{p+16}{7}[/tex]

[tex]\implies p-2=\frac{p+16}{7}[/tex]

⇒ Option B is incorrect.

Now, let x represents w and y represents p in the graph,

Then, the solution will be the intersection point of lines y=x+2 and y=7x-16,

Which is shown below,

⇒ Options C and D are incorrect.

Answers

Answer:

1 The pressure approaches infinity.

2 The function is undefined for V = 0.

3 There is an asymptote at V = 0.

The pressure tends to infinity.

Given information,

The equation [tex]p=\frac{8.31}{v}[/tex]

Where p= pressure,

v= volume

If the volume approaches [tex]0[/tex] then the pressure [tex]p=\frac{8.31}{v}[/tex] will reach to infinity.

Therefore, the pressure tends to infinity.

If 3n+m=14 and n+m=1, find the value of n-m.

Answers

Hey there! :D

We can subtract the two equations.

3n+m=14
n+m=1

3n-n=2n

m-m=0

14-1= 13

We are left with:

2n=13

Divide both sides by 2.

n=6.5

Plug that in to find m.

n+m=1

6.5+m=1

Subtract both sides by 6.5.

m=-5.5

Now, put the values for m and n into the last equation for the value.

n-m

6.5-(-5.5)

Two negatives make a positive.

6.5+5.5= 12

The value is 12.

Suppose the probability that a randomly selected man, aged 55-59, will die of cancer during the course of the year is StartFraction 300 Over 100 comma 000 EndFraction . How would you find the probability that at least 1 man out of 1,000 of this age will die of cancer during the course of the year?

Answers

1000 randomly selected

The question is an example of binomial distribution.

P(x=r) = nCr* p^r* q^(n-r) ( nCr = n! / ( (n-r)!*r! )

p = probability of die = 300/100000 = .003

P ( at least one man would die) = 1-P(at most one man would die)

= 1 - [ P(X =0) + P(X= 1)

Yes, It would be reasonable since thats about the weight of a skateboard.
However, the average skateboard is closer to 6 pounds. So, the skateboard in the question is very possible- but it would be really low quality.

Which BEST describes the speed and velocity of the graph?

A)
Both speed and velocity are changing.

B)
The speed and velocity remain constant.

C)
The speed is constant and velocity is changing.

D)
The velocity cannot be determined from the graph.

Answers

Answer:

A - Both speed and velocity are changing.

Step-by-step explanation:

Though the answer is option A but option D can also be true. The velocity cannot be completely determined from the graph. This is because, velocity is based on the direction and motion and the graph is not completely justifying this.

Though velocity cannot be determined, but it is clear from the graph that velocity is changing, because the speed is changing.

Therefore, option A is completely true.

According to the graph, speed is increasing. Velocity is speed plus direction, so velocity is also changing. And this is an acceleration graph, so you know since acceleration is a change in velocity, both speed and velocity are changing.

Answers

C: 700 units squared

Answer:

C) 700 unit².

Step-by-step explanation:

Given : A rectangular prism .

To find : What is the surface area of the rectangular prism below.

Solution : We have given that a rectangular prism with

Length = 14 units,

Width = 12 units

Height = 7 units.

Surface area of rectangular prism = [tex]2(length* width\ +\ height*width\ +\ height*length})[/tex].

Plugging the values

Surface area of rectangular prism = 2 ( 14* 12 + 7 *12 + 7 *14)

Surface area of rectangular prism = 2 ( 168 + 84 + 98)

Surface area of rectangular prism = 2 ( 350).

Surface area of rectangular prism = 700 unit².

Therefore, C) 700 unit².

1. A
Two triangles are said to be in perspective (or as some would call it, homologous) from a point if their corresponding vertices form three lines that intersect in that single point (called a colinear point). Desargues' theorem asserts that if two triangles are in perspective from a point, then they are also perspective from a line (called the perspectrix); for this reason perspective triangles are also calles coplanar triangles.
