Values

1) a = 1, b = 3, c = -1

2) a = 2, b = -3, c = 6

3) a = 8 b = 1, c = -7

Step-by-step explanation:

To get the values, you need to write each equation in the format of ax²+bx+c=0, therefore you can find out each of the values easily. However for the third box, you aren't give the 'b' value in the equation, so you would have to assume that this is '1'.

To get the 'Answer', just simply input each of these values into the quadratic formula using a calculator.

The Quadratic formula:

[tex]x=\frac{ -b +- \sqrt{^{b} -4ac} \\}{2a}[/tex]

Use this and input all of the values required in each place, then simplify down if you don't have a calculator to find the answer.

Instructions for a craft project say that the length of a piece of red ribbon should be 7 inches less than the length of a piece of blue ribbon.

a. How long is the red ribbon if the blue ribbon is:
10 inches?
27 inches?
X inches?

Answers

Answer:

If blue ribbon is 10 inches, red ribbon is 3 inches

If blue ribbon is 27 inches, red ribbon is 20 inches

If blue ribbon is x inches, red ribbon is x - 7 inches

Step-by-step explanation:

Given that,

The length of a piece of red ribbon should be 7 inches less than the length of a piece of blue ribbon.

Need to find,

How long red ribbon is if blue ribbon is 10 inchesHow long red ribbon is if blue ribbon is 27 inchesHow long red ribbon is if blue ribbon is x inches

--------------------------------------------------------------------------------------------------------------

How long is the red ribbon if the blue ribbon is 10 inches?

We know that the formula for find the length of the red ribbon is:

length of blue ribbon - 7 inches = length of red ribbon

Since we know the length of the blue ribbon (10 inches), we can apply that to the formula:

10 inches - 7 inches = length of red ribbon

So, what is 10 - 7? That gives us 3. So, the length of the red ribbon is 3 inches if the length of the blue ribbon is 10.

--------------------------------------------------------------------------------------------------------------

How long is the red ribbon if the blue ribbon is 27 inches?

We do the same as we did above to get 20 inches as the final answer because 27 inches - 7 inches gives us 20 inches as a difference.

--------------------------------------------------------------------------------------------------------------

How long is the red ribbon if the blue ribbon is x inches?

Since we do not know the value of x, we keep the length of the red ribbon to x - 7.

The length of the red ribbon is 3 inches if the blue ribbon is 10 inches.

The length of the red ribbon is 20 inches if the blue ribbon is 27 inches.

The length of the red ribbon is (X - 7) inches if the blue ribbon is X inches.

What is an expression?

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Length of blue ribbon = x

Length of red ribbon.

= x - 7

Now,

If x = 10
Length of red ribbon.

= 10 - 7

= 3 inches

If x = 27

Length of red ribbon.

= 27 - 7

= 20 inches

If x = X

Length of red ribbon.

= (X - 7) inches

Thus,

The length of the red ribbon is given above.

Answers

Answer:

(2x + 1) (x + 2)

Step-by-step explanation:

2x² + 4x + 1x + 2

They are already arranged, so you just have to find the GCF. 2x² + 4x  have the GCF of 2 and 1x + 2 have the GCF of 1.

2x (x + 2) + 1(x + 2)

Now you divide the whole thing by x + 2.

2x (x + 2) + 1(x + 2)/ x + 2

One of them cancels out  leaving (2x + 1) and (x+2)

A ball is thrown straight up from a height of 3 ft with a speed of 32 ft/s. Its height above the ground after x seconds is given by the quadratic function y = -16x2 + 32x + 3.

Answers

Answer:

19ft

Step-by-step explanation:

Given the height of a ball above the ground after x seconds given by the quadratic function y = -16x2 + 32x + 3, we can find the maximum height reached by the ball since we are not told what to look for.

The velocity of the ball is zero at maximum height and it is expressed as:

V(x) = dy/dx

V(x) = -32x+32

Since v(x) = 0

0 = -32x+32

32x = 32

x = 32/32

x = 1s

Get the height y

Recall that y = -16x² + 32x + 3.

Substitute x = 1

y = -16(1)²+32(1)+3

y = -16+32+3

y = -16+35

y = 19ft

Hence the maximum height reached by the ball is 19ft

what is the area to this

Answers

Answer:

600

Step-by-step explanation:

Area of Square:

= l*w

= 20x20 = 400

Area of Triangle:

= b*h/2

= 20*20/2

= 200

400 + 200 = 600

Good luck! <3

Answer:

The total area of the shape is 600 square centimetres.

Step-by-step explanation:

You can solve this by finding the area of the square and the triangle separately.

The area of any rectangle, including squares, is width times height. The bottom square then has an area of 20cm × 20cm, which equals 400cm²

The area of a triangle is have of its base width times its height.  It too has a width of 20cm and a height of 20cm, so its area is 20cm × 20cm ÷ 2, which equals 200cm²

Add them together for the full area of the shape:

400cm² + 200cm² = 600cm²

A table is formed by a set of points (x, P(x)), and represents a probability distribution if:

The sum of the probabilities is of 1.All probabilities are 0 or positive.

In this problem:

In the first table, there is a negative probability, which is P(X = 0) = -0.3.In the second and the fourth tables, the sums are of 1.2 and 0.8, respectively.

Hence, the table that represents a probability distribution is given as follows:
