Which is the graph of f(x) = x2 – 2x + 3?

Answers

Answer 1

Answer:

Step-by-step explanation:

We cannot factor this function out which tells us that there are no zeros. The graph backs this up because we can see that there are none. The easiest way to graph this would start by plugging in points and making a table for yourself.

Lets start by plugging in -1.

(-1)^2-2(-1)+3 =6, this means we have a point at (-1,6).

Now lets plug in 0.

(0)^2-2(0)+3= 3 (0,3)

For plugging in 1

(1)^2-2(1)+3=2 (1,2) (this happens to be the vertex)

And lastly lets plug in 2

(2)^2-2(2)+3=3 (2,3)

Depending on how many points are needed, keep plugging in numbers like we did above.

the total amount of fiber (in grams) in a package containing x apples and y oranges is given by the equation 5x + 10y = 110. is it possible for the package to contain 15 apples? EXPLAIN

Answers

Answer:

Step-by-step explanation:

The y intercept is the value of y when x = 0. Similarly, the x intercept is the value of x when y = 0. To find each of these, we separate the equation as shown in the attached image. After solving for x and y, we find that the y intercept is 11 and the x intercept is 22. For part e, we substitute 15 in for x. So instead of putting x in the equation, we will put 15 and solve for y. After solving, we see that y will equal 3.5. However, since we cannot have a "half apple" in the package, we see that it is not possible to have 15 apples in the package.

1 foot = 12 inches. 1 inch = 2.5 centimetres. Change 5 feet 10 inches to centimetres

Answers

I guess the answer should be 177.8 cm.

The measurement of 5 feet 10 inches to centimeters is 175 centimeters.

What is Unit of Measurement?

Units of measurement are defines ad the definite magnitude of a physical quantity. It is used to find a number that shows the amount of something.

Here we have to convert the units of measurement feet and inches to centimeters.

We have,

1 foot = 12 inches and 1 inch = 2.5 centimeters

We have to change 5 feet 10 inches to centimeters.

1 foot = 12 inches

⇒ 5 feet = 12 × 5 inches

= 60 inches

So, 5 feet 10 inches = 60 inches + 10 inches

= 70 inches

1 inch = 2.5 centimeters

70 inches = 70 × 2.5 centimeters

= 175 centimeters

Hence we got 5 feet 10 inches as 175 centimeters.

Explain why

Answers

Answer:

the correct option is number (3). It corresponds with the expression David factorised.

Step-by-step explanation:

David correctly factored the expression m² - 12m + 64, we want to check which one of the options he wrote.

(1) (m - 8)(m - 8) = (m - 8)²

= m² - 16m + 64

NOT THIS

(2) (m - 8)(m + 8) = m² - 8²

= m² - 64

NOT THIS

(3) (m - 16)(m + 4) = m² + 4m - 16m - 64

= m² - 12m - 64

THIS IS THE CORRECT OPTION AS IT CORRESPONDS WITH THE EXPRESSION DAVID FACTORISED

Convert the exponential equation to a logarithmic equation using the logarithm base (2)

of the right side (256) equals the exponent (8)

log2(256)=8

Step-by-step explanation:

In exponential form, the base (2 in this case) is raised to the exponent (8), resulting in the value on the right side of the equation (256).

In the given equation, we have:

Log₂ 256 = 8

This equation can be read as "the logarithm base 2 of 256 equals 8."

To express it in exponential form, we need to understand that logarithms and exponentiation are inverse operations.

In other words, if we have a logarithmic equation like this, we can convert it into an exponential equation by applying the exponentiation operation.

In this case, the logarithm is base 2, so the exponential form will have a base of 2 as well.

The exponent will be the value equal to the logarithm result. Thus, we can write the exponential form as:

2⁸ = 256

In this equation, 2 is the base and 8 is the exponent.

By raising 2 to the power of 8, we get the value of 256, which is equivalent to the logarithmic expression Log₂ 256 = 8.

Hence in exponential form, the base (2 in this case) is raised to the exponent (8), resulting in the value on the right side of the equation (256).
