Answer:

S2 + 355

Step-by-step explanation:

Given the expression to evaluate :

S2+54+18+46+237

Since the values are bound by the addition operator, we take the sum of the like terms ;

S2 + (54+18+46+237)

S2 + 355

Answer:

1) Using properties of the quadratic equation:

Here the height equation is:

h(t) = -16t^2 + 32t + 6

We can see that the leading coefficient is negative, this means that the arms of the graph will open downwards.

Then, the vertex of the quadratic equation will be the maximum.

Remember that for a general quadratic equation:

a*x^2 + b*x + c = y

the x-value of the vertex is:

x = -b/2a

Then in our case, the vertex is at:

t = -32/(2*-16) = 1

The maximum height will be the height equation evaluated in this time:

h(1) = -16*1^2 + 32*1 + 6 = 22

The maximum height is 22ft

2) Second method, using physics.

We know that an object reaches its maximum height when the velocity is equal to zero (the velocity equal to zero means that, at this point, the object stops going upwards).

If the height equation is:

h(t) = -16*t^2 + 32*t + 6

the velocity equation is the first derivation of h(t)

Remember that for a function f(x) = a*x^n

we have that:

df(x)/dx = n*a*x^(n-1)

Then:

v(t) = dh(t)/dt = 2*(-16)*t + 32 + 0

v(t) = -32*t + 32

Now we need to find the value of t such that the velocity is equal to zero:

v(t) = 0 = -32*t + 32

       32*t = 32

            t = 32/32 = 1

So the maximum height is at t = 1

(same as before)

Now we just need to evaluate the height equation in t = 1:

h(1) = -16*1^2 + 32*1 + 6 = 22

The maximum height is 22ft

Answer:

[tex]\dfrac{15}{2}[/tex]

Step-by-step explanation:

The average speed of the Erin is 120/16 mph

Here,

Numerator = 120

Denominator = 16

mph = miles per hour

We need to find an expression expressed as a decimal.

So,

[tex]\dfrac{120}{16}=\dfrac{2\times 3\times 2\times 2\times 5}{2\times 2\times 2\times 2}\\\\=\dfrac{15}{2}[/tex]

So, the final answer is [tex]\dfrac{15}{2}[/tex].

Answer:

Step-by-step explanation:

Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, dilation and translation.

Dilation is the increase or decrease in size of a figure by a factor k. If k > 1, then the dilation is an increase whereas if k<1, then the dilation is a decrease.

From the diagram, since triangle LMN is dilated by a factor of 1/4, hence the size of LMN is reduce. Therefore:

L'M' = (1/4)LM, L'N' = (1/4)LN, N'M' = (1/4)NM

Also, the distance from point P to N' is one-fourth of the distance from point P to N.

The correct option is highlighted in the image attached.

Answer:

h = 7

Step-by-step explanation:

-3h + 6 = -15

Get rid of the 6 by subtracting it from both sides.

-3h + 6 - 6 = -15 - 6

-3h = -21

Get rid of the -3 by dividing it from both sides.

-3h/-3 = -21/-3

h = 7

Step-by-step explanation:

Domain = all possible values of x

From the graph, we can tell that x can be any value as the graph goes on forever.

Hence Df = {x: x <== All real numbers}

[tex]147.6\:\mathrm[/tex]

Step-by-step explanation:

The perimeter of a polygon is simply sum of the lengths of all sides of the polygon.

Therefore, we can find this polygon's perimeter by adding up the length of each of its sides:

[tex]9.8+9.8+11.7+9.8+21.5+21+11.7+9.8+31.3+11.2=\boxed{147.6\:\mathrm{m}}[/tex]

Since there is a lot to keep track of, I'd recommend picking any side and moving clockwise/counter-clockwise until you get all sides.

Answer:

Not sure but heres the proportional factor.

Step-by-step explanation:

The image is blurry and is hard to make out what the number for width is. However you can find the proportionality factor between the phones by dividing the large phone height by the small phone height. So 6.21in/5.4in, you get 1.15in, this means that the larger phone is 1.15in bigger than the smaller phone. Apply this number to the width and you will find the width of the larger phone since both phones are proportional. So you do width × 1.15 to get the width of the larger phone.

Answer:

18

Step-by-step explanation

Let's say that  the amount of 5 dollar bills is x and 20 dollar bills is y, with this we can make an equation

x + y = 24

With that we can say that

5x + 20y = 210

Because that is how much each bill costs and the amount of which will equal a total of 210

Solve this systems of equations using elimination

5x + 5y = 120

-5x - 20y = -210

-15y = -90

y = 6

Plug in y = 6 to the first equation.

x + 6 = 24

x = 18

18 is the amount of 5 dollar bills.
