Answer:

I'm sure you mean miles, but the car will travel 135 mites.

Step-by-step explanation:

(180/4)3 = 135 miles. The car will be traveling at 45 miles per hour since 180 miles divided by four hours is 45, then you can multiply that by three to get the distance the car will travel in the next three hours. A function that models this equation is f(x)=45x.

Remark

This is an incredibly beautiful problem! It is solved mostly by algebra. r = 1 and the height will therefore be 2

Equations

l^2 + r^2 = l^2

l is the slant height.

Solution

SA = π * l * r + π r² = π(1 + √5)          Divide both sides by π

Find l

l * r + r^2 = 1 + √5

l^2 = r^2  + h^2

l^2 = r^2 + (2r)^2

l^2 = 5r^2

l = √5 * r

Now go back to this equation to find r

l * r + r^2 = 1 + √5                               Substitute the value for l

√5 r * r + r^2 = 1 + √5                         On the left pull out r^2

r^2 (1 + √5) = 1 + √5                            Divide by 1 + √5

r^2 = 1                                                  Take the square root on both sides

sqrt(r^2) = sqrt(1)

r =1

Therefore h = 2

Volume of the cone.

V = 1/3 * π r² h

V = 1/3 * π 1² 2

V = 2/3 * pi

Answer:

x is 10

Step-by-step explanation:

Form the diagram, you can see that UV is parallel to TS, this means that <UVS  = < UTS

Given

<UVS = 5x + 38

<UTS = 12x - 28

Since the sum of opposite angle of a quadrilateral is 180 degrees, hence;

5x + 38 + 12x - 28 = 180

Collect like terms

5x + 12x - 28 + 38 = 180

17x + 10 = 180

17x = 180-1-

17x = 170

x = 170/17

x = 10

hence the value of x is 10

What is the height of the cylinder?

A. 35

B. 42

C. 25

D. 17

E. 32

Answer:

To find the missing angle you have to use cosine so it would be cos^-1(26.2/27) since cosine is adjacent over hypotenuse so the missing angle x is 13.98 but rounded to the nearest tenth its approximately 14.

Answer:

  a) 2(L+W)=420; L-W=110

  b) length: 160 ft; width: 50 ft

Step-by-step explanation:

The formula for the perimeter (P) in terms of length (L) and width (W) is ...

  P = 2(L+W)

We can use this as one of the equations. The other will relate the length and width according to their difference:

  L -110 = W

Substituting the given perimeter in the above equation, our system of equations is ...

Substituting for W in the first equation gives ...

  420 = 2(L +(L -110))

  210 = 2L -110

  320 = 2L

  160 = L

  160 -110 = W = 50

The planting area is 160 feet long by 50 feet wide.

Comment on the question

Most national flags have a length/width ratio of 1.5 or 2. The flags of Vatican City and Switzerland are square (1.0). The longest flag is that of Qatar, with an aspect ratio of width:length = 11:28, about 2.545. The "national flag" described here has an aspect ratio of width:length = 5:16, or 3.2. Apparently, it is not to scale, or not from Earth. (The US flag aspect ratio is 1.9.)

Answer: {(0, 1), (2, 3), (4, 5), (7, 8)}

Step-by-step explanation:

For the function:  y = x - 1    (y is one less than x)

If x =1 , y= 0

if x= 3 . y= 2

If x = 5 , y= 4

If x= 8 , y= 7

So it is same as

x y

1 0

3 2

5 4

8 7

But different from {(0, 1), (2, 3), (4, 5), (7, 8)} [here x is 1 less than y]

So,  the complete statement would be : All of the following represent the same function except {(0, 1), (2, 3), (4, 5), (7, 8)} .

Answer:

answer B

Step-by-step explanation:

I got this answer right on my test

Table 1 and table 3 are represent linear functions of x.

A linear function is a function which forms a straight line in a graph. It is generally a polynomial function whose degree is utmost 1 or 0. Although the linear functions are also represented in terms of calculus as well as linear algebra.

Given are four tables, we need to find that which of them shows linear functions of x,

Linear functions will have the ratios of x and y coordinates, constant.

In table 1 :-

x/y = -1/2

-2/4 = -1/2

-3/6 = -1/2

Since the x and y coordinates are constant, therefore, the function is linear.

In table 2 :-

x/y = 1/1 = 1

2/4 = 1/2

3/9 = 1/3

Since the x and y coordinates are not constant, therefore, the function is not linear.

In table 3 :-

x/y = 1/5

2/10 = 1/5

3/15 = 1/5

Since the x and y coordinates are constant, therefore, the function is linear.

In table 4 :-

x/y = 1/1 = 1

2/8 = 1/4

3/27 = 1/9

Since the x and y coordinates are not constant, therefore, the function is not linear.

Hence, table 1 and table 3 are represent linear functions of x.

Answer:

The answer is ;

9x/2y^2

Step-by-step explanation:

Here, we want to simplify as far as possible

Let us take all the numbers one after the other

All numbers on numerator and denominator;

(4 * 9)/(2 * 4) = 9/2

All x

(x^2 * x^2)/(x^2 * x) = x

All y

(y^4 * y^4)/(y * y^9) = y^8/y^10 = 1/y^2

So the complete answer is;

9/2 * x * 1/y^2

= 9x/2y^2
