Answer is False.

You can check by doing a^2 + b^2 = C^2

(7)^2 + (9)^2 = (11)^2

49 + 81 = 121

130 = 121

This is not a true statement, which makes it false. This is a triangle, but not a right one.

You can check whether this is true using Pythagoras' Theorem. The Pythagorean Theorem:

a² + b² = c², where c is the hypotenuse of a right triangle.

Let's plug in the given values and check the validity of the statement.

a² + b² = c²

7² + 9² = 11²

49 + 81 = 121

130 = 121

This is false. Thus,

Answer:

False - a triangle with side lengths 7, 9, and 11 is not a right triangle.

What is the vertex of the function?

egoroff_w [7]

<h2>Explanation:</h2><h2></h2>

Here you haven't provided any function, so I'll assume this one:

$f(x)=3x^2-18x+33$

This is a quadratic function whose graph represents a parabola. Any parabola has its vertex at the point:

$V(x,y) \\ \\ \\ x=-\frac{b}{2a} \\ \\ y=f(-\frac{b}{2a}) \\ \\ \\ where: \\ \\ \\ f(x)=ax^2+bx+c \\ \\ \\ So: \\ \\ a=3 \\ \\ b=-18 \\ \\ c=33$

Therefore:

$x=-\frac{(-18)}{2(3)}=3 \\ \\ f(3)=3(3)^2-18(3)+33=27-54+33=6$

Therefore, the vertex is:

$\boxed{V(3,6)}$

Answer:

B. l = (S - πr^2) / πr

Step-by-step explanation:

S = πrl + πr^2 solve for l

πrl = S - πr^2

l = (S - πr^2) / πr

Answer is B. l = (S - πr^2) / πr

You have decided to purchase a car for $19,000. The credit union requires a 10% down payment and will finance the balance with a

<h2>○=> <u>Correct option</u> :</h2>

$\color{plum} \bold{ \tt \: \bold{C. \$20,652.00}}$

<h3>○=> <u>Steps to derive correct option</u> :</h3>

Selling price of a car = $19,000

Percentage of sales tax in the city = 8.3%

Sales tax :

$= \tt \frac{8.3}{10 \times 100} \times 1900$

$= \tt \frac{8.3 \times 19000}{1000}$

$= \tt \frac{1577000}{1000}$

$\color{plum} = \tt \$1577$

Thus, the sales tax on the car = $1577

Cost of license and title = $75

Total price of car :

= Cost price of car + Sales tax + cost of license/title

$= \tt19000 + 1577 + 75$

$\color{plum} = \tt \$20652$

Thus, the total purchase price of the car = $20,652.00

Therefore, the correct option is <em>(C) $20,652.00</em>
