Which function is represented by the graph ?!

Answer:

19.25 cm.

Step-by-step explanation:

I multiplied 7.7 by 2.5 and got 19.25 cm. Plus, you should have a higher chance of getting it right since it measures 7.7 cm in length

(For the people who need the actual answer, It's 19.25 ft.)

Answer:

66.14inches

Step-by-step explanation:

pyhtgreom therom

75^2+b^2 = 100^2

5625 + b^2 = 10,000

subtract both sides by 5625

b^2 = 4375

square root both sides

b = 66.14

Answer:

X=5 y=-2

Step-by-step explanation:

Set them equal to each other so...

-2x+8=3x-7

Simplify by balancing out the equation so

-5x=-1

So x=5

Now plug it into either y equation

-2(5)+8

-10+8

Y=-2

Hope this helps!

Answer:

12.6

Step-by-step explanation:

you basically subtract 32.4 and 45 to get your final answer because if a question has the words " how much more " you will most likely have to subtract or include subtraction

Answer: 20 sq units

Step-by-step explanation:

A quick sketch graph will show the right angle is at (-3 ,4)

The lengths of the shorter sides are both sqrt(2^2 + 6^2) = sqrt(40)

Area = 1/2 x (sqrt(40))^2 = 20

If you didn’t have a right angle you could find the lengths of all sides a, b and c

Calculate the semi perimeter s = (a+b+c) / 2

And the area = sqrt(s(s-a)(s-b)(s-c))

Try and use this method to check the first one!

Answer:

60

Step-by-step explanation:

he bought 6 so you need to subtract 6

which 36-6=30

and double 30 is 30

so its 60

Answer:

x = 400 when y = 100

Step-by-step explanation:

This is a question in relation to direct variation.

y ∝ [tex]\sqrt{x}[/tex]

y = k [tex]\sqrt{x}[/tex]

Given that, y = 45, x = 81. Then;

45 = k [tex]\sqrt{81}[/tex]

45 = 9k

k = [tex]\frac{45}{9}[/tex]

k = 5

Thus the relationship among the variables is;

y = 5 [tex]\sqrt{x}[/tex]

If y = 100, then;

100 = 5 [tex]\sqrt{x}[/tex]

[tex]\sqrt{x}[/tex] = [tex]\frac{100}{5}[/tex]

[tex]\sqrt{x}[/tex] = 20

x = [tex](20)^{2}[/tex]

x = 400

Therefore, x = 400 when y = 100.

Answer:

6

Step-by-step explanation:

its a right angle so to find a side use a Pythagorean theorem

Pythagorean theorem =

[tex]a^2+b^2=c^2[/tex]

[tex]a^2+b^2[/tex] are the sides

[tex]c^2[/tex] is the hypotenuse

In this case we need the hypotenuse

[tex]3\sqrt{3} ^2 + 3^2 = c^2[/tex]

[tex]27 + 9=c^2[/tex]

[tex]36=c^2[/tex]

the opposite of squaring is square rooting so:

[tex]\sqrt{36} =6[/tex]

therefore the answer is 6 ^-^

Answer:

b = 4

Step-by-step explanation:

[tex]2(-2b) + 2b = -8[/tex]

[tex]=> -4b + 2b = -8[/tex]

[tex]=> -2b = -8[/tex]

[tex]=> \frac{-2b}{-2} = \frac{-8}{-2}[/tex]

[tex]=> b = 4[/tex]

Answer:

(hy)-(hx)=P

Step-by-step explanation: to get the total price of stock you multiply the cost of one share by how many shares were bought. After being sold years later they made a profit, you must subtract the total cost from this profit to find the total profit.

Answer:

14 inches for every side

Step-by-step explanation:

44/4 = 22

circumfrence of half circle is 3.14r = 22

22/3.14 is about 7

the radius is half the side length so multiply 7 by 2 to get 14

Answer:

probability of an electric power outage shipboard is 0.075 or 7.5 %

Step-by-step explanation:

Given the data in the question;

Probability of engine malfunction = 25% = 0.25

Probability of generator malfunction = 10% = 0.1  

Probability of generator being repaired = 50% = 0.5

probability of an electric power outage shipboard = ?

To get the probability of an electric power outage shipboard, we use the expression;

probability of an electric power outage = 2[tex]_c_1[/tex] × p( Probability of generator malfunction ) × p( Probability of generator being repaired ) × ( 1 - p( Probability of engine malfunction ) )

so we substitute in our given values;

probability of an electric power outage = 2 × 0.1 × 0.5 × ( 1 - 0.25 )

probability of an electric power outage = 2 × 0.1 × 0.5 × 0.75

probability of an electric power outage = 0.075 or 7.5 %

Answer:

(y^3-2)(x^2-2)

Step-by-step explanation:

x^2y^3-2y^3 can be factored. This will be equal to y^3(x^2-2). Then for the other half it will be equal to -2(x^2-2). Because the insides are the same, the equation is the outside two number y^3 and -2 added together time the inside number x^2-2. This will make the expression (y^3-2)(x^2-2).

Answer:

  11.4

Step-by-step explanation:

Put the given coordinates in the distance formula and do the arithmetic.

  d = √((x2 -x1)² +(y2 -y1)²)

  d = √((1 -(-8))² +(7 -0)²) = √(9² +7²) = √130

  d ≈ 11.4 . . . . units

The distance between the two points is about 11.4 units.
