Answer:

Step-by-step explanation:

Since the problem stated that the 2 lines are tangent, you can then tell that the triangle is a right triangle.

By using the Pythagorean Theorem, the missing side, "x", is equal to [tex]\sqrt{8.4^2+11.2^2}[/tex], which equals 14

Answer:

18 OZ is better$1.75 to buy

Answer:

10 degrees BELOW = -10

50°F = 50

A LOSS of 20 = -20

Altitude: 15000

35 ft BELOW = -35

120 ft BELOW = -120

Step-by-step explanation:

Area of circle:

A=π*(r^2)=π*(16^2)=256π ft^2

Area of the figure:

A=(3*256π)/4=192π=603.185=603.18 ft^2

Answer: the answer will be -15.5, but this number is not in the choices given, so I guess you made a mistake while writing the equation

Step-by-step explanation:

6q+8=-9-76

6q+8=-85               Subtract 8 from both sides

6q=-93                   Divide both sides by 6

q=-15.5

Drawing a table to show the different weather and mood options :

The degree of freedom :

________ WEATHER ________

__________Rain ____ sunny _____ cloudy

Happy

|

Not happy

Here, we have a contingency table formatted in rows and columns

The columns = 3

The rows = 2

Degree of freedom :

(rows - 1) * ( columns - 1)

(2 - 1) * (3 - 1)

1 * 2

= 2

The degree of freedom = 2

Plot these points

(-3,0)

(-5,0)

(-4,1)

(-2,-3)

(-6,-3)

Step-by-step explanation:

Let find the zeros of the equation.

We can factor this equation.

Factor out the -1.

[tex] - 1( {x}^{2} + 8x + 15)[/tex]

Factor using AC method

[tex] - 1(x + 3)(x + 5)[/tex]

Set all the terms equal to zero.

[tex]x + 3 = 0[/tex]

[tex]x + 5 = 0[/tex]

[tex]x = - 3[/tex]

[tex]x = - 5[/tex]

So our x intercepts are -3,0 and -5,0.

To find our vertex, apply the -b/2a.

[tex] \frac{8}{ - 2} = - 4[/tex]

Then

Substitute-4 for x.

[tex]y = - {4}^{2} - 8( - 4) - 15 = 1[/tex]

So our vertex is at (-4,1).

Find some other points like -2 and -6.

To find -2, substitute-2 into the quadratic.

[tex]y = - ( { - 2}^{2}) - 8( - 2) - 15 = - 3[/tex]

So -2,-3.

Since y=-4 is the axis of symmetry

-6,-3

The 5 points which satisfies the quadratic equation y = −x² − 8x − 15 is

( -5 , 0 ) ( -1 , -8 ) , ( -2 , -3 ) , ( 4 , 1 ) , ( -3 , 0 ) and the vertex point is ( 4 , 1 )

What is Quadratic Equation?

A quadratic equation is a second-order polynomial equation in a single variable x , ax² + bx + c=0. with a ≠ 0. Because it is a second-order polynomial equation, the fundamental theorem of algebra guarantees that it has at least one solution. The solution may be real or complex.

Given data ,

Let the quadratic equation be represented as A

Now , the value of A is

y = −x² − 8x − 15

On simplifying the equation , we get

y = -1 ( x² + 8x + 15 )

On factorizing the equation , we get

y = -1 ( ( x + 5 ) ( x + 3 )

So , the 2 values for x is -5 , -3

So , the two points are ( -5 , 0 ) and ( -3 , 0 )

The vertex will be -b/2a

Substituting the values in the equation , we get

The vertex = -8/2 = -4

So , when x = -4

y =  -1 ( ( x + 5 ) ( x + 3 )

y = -1 ( 1 x -1 )

y = 1

So , the vertex is at the point ( 4 , 1 )

Now , when x = -1

y = -1 ( ( x + 5 ) ( x + 3 )

y = -1 ( 4 x 2 )

y = -8

So , the point is ( -1 , -8 )

Now , when x = -2

y = -1 ( ( x + 5 ) ( x + 3 )

y = -1 ( 3 x 1 )

y = -3

So , the point is ( -2 , -3 )

Hence ,

The 5 points which satisfies the quadratic equation y = −x² − 8x − 15 is

( -5 , 0 ) ( -1 , -8 ) , ( -2 , -3 ) , ( 4 , 1 ) , ( -3 , 0 ) and the vertex point is ( 4 , 1 )

Answer:

60

Step-by-step explanation:

They sold 60 baked goods because 75% of 80 is equal to 60.

Answer:

60 baked goods

Step-by-step explanation:

To find the answer to this question, you will need to multiply 80 by 75%.

Now this is very simple.

Some calculators will actually give you the option to multiply by a percent. Just type 80×75% and you'll get 60.

There is another way to do this.

You could also just solve 80×.75 due to the fact that .75 is equal to 75%.

Answer:30 centimeters

Step-by-step explanation:

The bigger square with an area of 144 cm squared has a perimeter of 100 with each side equal to 25. You find this by seeing that 25 times 25 equals the area of the square. Same thing with the smaller square 5 times 5 equals 25. Now that we have the perimeter for the sides that are connected to the square (25) and (5), multiply those together just as you would with finding the area of a square. (25)(5)=60. Since this is a triangle you divide your answer in half which is 30.
