Good luck on your assignment...

Answer:

Step-by-step explanation:

You didn't list any choices here, but it doesn't matter. There's only one way to get to the answer so we'll work it through and you can match it up to your choices. The only thing I don't know is how pens is identified if pencils is "p". So I'm going to use the words "pens" and "pencils" and you can take it from there at the end.

If a pen's cost IS twice as much as a pencil...

the word "is" indicates an equals sign, the words "twice as much" indicates 2 multiplied by something. To put that above sentence into an algebraic expression:

pen = 2 pencils

Now for the money part of this.

The total cost of 11 pens and 11 pencils IS (there's that word again!) 2.10

Therefore,

11 pens + 11 pencils = 2.10

But we know from the first expression that pen = 2 pencils so we make the substitution:

11(2 pencils) + 11 pencils = 2.10

I'm not sure how far you are to go with this. That's the main equation you need to solve this. If you were to go further with it you would distribute the 11 into the set of parenthesis to get:

22 pencils + 11 pencils = 2.10 and combine like terms:

33 pencils = 2.10 so

1 pencil is approximately $.06

Answer:

16x + 8y -3/2

Step-by-step explanation:

The expression can be represented mathematically as follows.

-2(-8x - 4y + 3/4) = - 10x - 8y - 1 1/4

-2(-8x - 4y + 3/4) = - 10x - 8y - 5/4

The first way to solve this expression is by opening the bracket by multiplying the outside values by the inner values.

-2(-8x - 4y + 3/4)

Multiply -2 by all the values in the brackets

-2 × - 8x = 16x not - 10x

-2 × - 4y = 8y not -8y

-2 × 3/4 = -6/4 = - 3/2  not -5/4

Bringing the value together the expected answer will be 16x + 8y -3/2 and not  - 10x - 8y - 5/4.

Answer:

a) 0.68

b) 0.08

c) 0.74

Step-by-step explanation:

Given that:

Probability of hitting bulls eye, P(B) = 0.26

Probability of an inner, P(I) = 0.42

Probability of an outer, P(O) = 0.24

a) Probability of hitting an inner or better (inner or bulls eye):

P(I or B) = P(I [tex]\cup[/tex] B)

Formula for P(P [tex]\cup[/tex] Q)  where P(P) and P(Q) are the probabilities of two mutually exclusive events i.e. having nothing in common:

P(P [tex]\cup[/tex] Q)  = P(P) + P(Q)

P(I [tex]\cup[/tex] B)  = P(I) + P(B) = 0.26 + 0.42 = 0.68

b) Probability of failing to hit the target:

P(F) = 1 - (P(B)+P(I)+P(O))

P(F) = 1 - (0.26 + 0.42 + 0.24)) = 1 - 0.92 = 0.08

c) Probability of failing to score a bulls eye:

P(B)' = 1 - P(B) = 1 - 0.26  = 0.74

So, the answers are:

a) 0.68

b) 0.08

c) 0.74

Answer:

The resultant velocity is 12.21 m/s.

Step-by-step explanation:

We are given that the water from a fire hose follows a path described by y equals 2.0 plus 0.9 x minus 0.10 x squared ​(units are in​ meters).

Also, v Subscript x is constant at 10.0 ​m/s.

The water from a fire hose follows a path described by the following equation below;

[tex]y=2.0 + 0.9x-0.10x^{2}[/tex]

The velocity of the [tex]x[/tex] component is constant at =  [tex]v_x=10.0 \text{ m/s}[/tex]

and the point at which resultant velocity has to be calculated is (9.0,2.0).

Let the velocity of x and y component be represented as;

[tex]v_x=\frac{dx}{dt} \text{ and } v_y=\frac{dy}{dt}[/tex]

Now, differentiating the above equation with respect to t, we get;

[tex]y=2.0 + 0.9x-0.10x^{2}[/tex]

[tex]\frac{dy}{dt} =0 + 0.9\frac{dx}{dt} -(0.10\times 2)\frac{dx}{dt}[/tex]

[tex]\frac{dy}{dt} = 0.9\frac{dx}{dt} -0.2\frac{dx}{dt}[/tex]

[tex]v_y = 0.9v_x -0.2v_x[/tex]

[tex]v_y = 0.7v_x[/tex]

Now, putting [tex]v_x=10.0 \text{ m/s}[/tex] in the above equation;

[tex]v_y = 0.7 \times 10.0[/tex] = 7 m/s

Now, the resultant velocity is given by = [tex]v=\sqrt{v_x^{2}+v_y^{2} }[/tex]

                            [tex]v=\sqrt{10^{2}+7^{2} }[/tex]

                               = [tex]\sqrt{149}[/tex] = 12.21 m/s

See attached graph: v is on the y-axis and t is on the x-axis

Sum = 20.8333

Step-by-step explanation:

A geometric series has a general formula of:

[tex]\sum ar^n[/tex]

Where 'a' is the initial term, 'n' is the number of terms, and 'r' is the constant ratio. If |r| < 1 than the series converges.

In this particular case, the initial term is a=25, and each term is being divided by -5, or multiplied by -0.2, so the general form would be:

[tex]\sum 25*(-0.2)^n[/tex]

Since 0.2 < 1.0, the series converges.

The sum of the series is given by:

[tex]S=\frac{a}{1-r}\\S=\frac{25}{1-(-0.2)}\\S=20.8333[/tex]

The sum is 20.8333.

The geometric series converges and the sum is equal to 20.83.

A geometric series is the sum of an infinite number of terms that have a constant ratio between successive terms .

A geometric series has a general formula of:

∑arⁿ

Where 'a' is the initial term, 'n' is the number of terms, and 'r' is the constant ratio. If |r| < 1 than the series converges.

In this particular case, the initial term is a=25 and each term is divided by -5 or multiplied by (-0.2)

Therefore r = -0.2 and as it is <1 therefore the series converges

The sum of a convergent series is

S = a/(1-r)

S = 25/(1-(-0.2))

S= 25/1.2

S = 20.83

Therefore the sum of the series is 20.83

An x value of 0 can only be plugged into the equation that has a domain that includes 0. The first function's domain is between -2 and -4, so 0 is not included in that domain. In the third function, the domain is between 1 and 3, so 0 is not included in that domain, either. The middle function's domain does include 0 (0 falls between -2 and 1) so we can only evaluate this function at an x value of 0.

-40*h+280

Step-by-step explanation:

Let s define the function f which represents Emily's distance from home

at h = 0 Emily is 280 miles away from home

so f(0)=280

as she is traveling back at a rate of 40 miles per hour

f(h)=-40*h+280

the graph is below

The required equation for the distance is y = 280 - 40h and graph is shown below.

In unit time, the distance covered by any object is called speed.

In mathematical term, Speed is express as S = D/T,

where S=speed, D=distance, T= time.

Given that,

Distance of Emily from her home = 280 miles,

The speed of Emily of coming back = 40 miles per hour.

In h hours, the distance covered by Emily = 40h

Let the remaining distance is y,

So the equation can be written as,

y=x+ 3

Step-by-step explanation:

The given equation is y = x, which is parallel to y = x + 3

Also, the equation I chose has an x-intercept of -3.

The equation of the line that is parallel to the given line and has an x - intercept of - 3 is,

⇒ y = 2/3x - 1

The equation of line in point-slope form passing through the points

(x₁ , y₁) and (x₂, y₂) with slope m is defined as;

⇒ y - y₁ = m (x - x₁)

Where, m = (y₂ - y₁) / (x₂ - x₁)

Given that;

Two points on the line are (3, 1) and (0, -1).

Now,

Since, The equation of line passes through the points (3, 1) and (0, -1).

So, We need to find the slope of the line.

Hence, Slope of the line is,

m = (y₂ - y₁) / (x₂ - x₁)

m = (- 1 - 1) / (0 - 3)

m = - 2 / - 3

m = 2/3

Thus, The equation of line with slope 2/3 is,

⇒ y - 1 = 2/3 (x - 3)

⇒ y - 1 = 2/3x - 2

⇒ y = 2/3x - 1

Therefore, The equation of the line that is parallel to the given line and has an x - intercept of - 3 is,

⇒ y = 2/3x - 1

The maximum height the projectile reaches is 100 feet

Step-by-step explanation:

Notice that the given equation representing the height of the projectile is a quadratic equation which negative leading coefficient (-16). Such type of equations would have a parabola that branches downwards as its graph.

therefore, what we need to find is the coordinates of the top vertex of that parabola. We can use for such the typical formula for the x-position of the vertex of a parabola with standard equation:

[tex]f(x)=ax^2+bx+c[/tex]

with x-position of the vertex given by:

[tex]x_v=\frac{-b}{2a}[/tex]

Then in our case  ([tex]H(t)=-16t^2+16t+96[/tex])  we have:

Horizontal position of the vertex given by:

[tex]t_{vertex}=\frac{-16}{2(-16)} =\frac{1}{2}[/tex]

and now we can find the maximum height plugging this value into the height expression:

[tex]H(t)=-16(\frac{1}{2}) ^2+16\,(\frac{1}{2})+96=-4+8+96=100\,\,ft[/tex]

A. 52% and B. 104/200

Step-by-step explanation:

To find the answer, we first have to find how many pet owners own cats. As percentages are x/100, when we have x/200 we divide the numerator and denominator by 2 to bring the fraction to 48/100. (96/200 divided by 2 equals 48/100). Now that we have the percentage of pet owners that own cats (48%), we need to find how many do not own cats. To do so, we just subtract 100-48 to get 52. Then, we do the same to the fraction of 96/200. (200-96 = 104). This brings our answers to A. 52% and B. 104/200

The percentage of owners that do not own cat is 52%

A percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate percent of a number, divide the number by the whole and multiply by 100. Hence, the percentage means, a part per hundred. The word per cent means per 100. It is represented by the symbol “%”.

Given here, 96 out of 200 pet owners own cats then the owners who do not own cat are 104

Therefore the number of non cat owners in percentage terms is

= (104/200) ×100

= 52.5%

Hence, the answer is 52.5%
