Just remember to divide the diameter by two to get the radius. If you were asked to find the radius instead of the diameter, you would simply divide 7 feet by 2 because the radius is one-half the measure of the diameter. The radius of the circle is 3.5 feet. You can also use the circumference and radius equation

Answer:

The range of the graph is {y: y ∈ R, -6 ≤ y ≤ 8}

Step-by-step explanation:

The domain is the set of values of the input (x)

The range is the set of values of the output (y)

In the given figure

∵ x is the input

∴ The set of the values of x is the domain

∵ Y is the output

∴ The set of the values of y is the range

∵ The smallest value of y is -6

∵ The greatest value of y is 8

→ That means values of y of the graph are from -6 to 8

∴ -6 ≤ y ≤ 8

∴ The range = {y : y ∈ R, -6 ≤ y ≤ 8}

∴ The range of the graph is {y: y ∈ R, -6 ≤ y ≤ 8}

If someone eats 3 sundaes in 9 minutes what portion of a sundae can they eat in one minute

Sidana [21]

Answer:

Number of sundaes eaten per minute = 3 sundaes

Step-by-step explanation:

Number of sundaes eaten in 3 minutes = 9 Sundaes

So, by UNITARY METHOD:

Number of sundaes eaten in 1 minute = $\frac{\textrm{Sundaes eaten in 9 minutes}}{\textrm{3 minutes}}$

= $\frac{9 }{3 } = 3$

So, number of sundaes eaten per minute = 3.

If the following is a polynomial function, then state its degree and leading coefficient. If it is not, then state this fact.

brilliants [131]

Degree: 5; leading coefficient: 10

Option D is correct.

Step-by-step explanation:

We need to identify if $f(x) = 10x^5 + 7x^4+5$ is a polynomial function, then state its degree and leading coefficient or not.

Polynomial

A polynomial is an algebraic expression containing two or more terms that have same variables but may have different exponents combined through mathematical symbol(+,-,*or/)

So, $f(x) = 10x^5 + 7x^4+5$ is a polynomial function

Degree of polynomial

The degree of polynomial is the highest degree obtained by sum of all exponents of individual terms in the polynomial.

So, $f(x) = 10x^5 + 7x^4+5$ has highest degree 5

Degree = 5

Leading Coefficient

The leading coefficient is the coefficient of first term of the polynomial.

So, $f(x) = 10x^5 + 7x^4+5$ has leading coefficient = 10

So, Leading coefficient = 10

So, Degree: 5; leading coefficient: 10

Option D is correct.
