What is a right-angle triangle?

It is a type of triangle in which one angle is 90 degrees and it follows the Pythagoras theorem and we can use the trigonometry function.

A right-angle triangle has sides with lengths 200 ft and 200 ft.

By Pythagoras theorem, we have

H² = P² + B²

H² = 200² + 200²

H² = 40000 + 40000

H² = 80000

H = 200√2

H = 282.84 ft

Alma is going to walk through the park from Point A to Point B is 282.84 ft.

sub 2 for any "x"

3(2)^2-2(2)+1

6^2-4+1 i dont know if you need to simplify even more but if you do

36-4+1 32+1 31

i hope this helps you!

Answer:

The answer is 9.

Step-by-step explanation:

Hey there, so it looks to me that you just have to subsitute 2 in for x, and solve the equation. Like this.

1. Plug in X: 3(2)^2 -2(2) + 1

2. Solve exponents (2)^2 = 4, so the equation is 3(4) - 2(2) + 1

3. Multiplication: 3 × 4 = 12, and -2 × 2 = -4, so the equation is 12 - 4 + 1

4. Addition: -4 + 1 = -3, so it is now 12-3

5. Subtraction: 12-3 = 9, so the answer is 9!

I hope this helps.

Answers

Answer:

[tex]f(x) = {x}^{2} - 13x + 30[/tex]

Step-by-step explanation:

A quadratic equation may be expressed as a product of the two binomials. The roots of the equations are 3 and 10, so the factors are (x-3) and (x-10).

f(x) = (x-3)(x-10)

f(x) = x^2 - 13x + 30

for fraction form 361/50 you can simplify from there

Answer:

361/50 or 7[tex]\frac{11}{50}[/tex]

Step-by-step explanation:

7.22 = 722/100 = 361/50 = 7 11/50

The number 7.22 can be written using the fraction 722/100 which is equal to 361/50 when reduced to lowest terms.

It is also equal to 7 11/50 when written as a mixed number.

You can use the following approximate value(s) for this number:

7.22 =~ 7 2/9 (if you admit an error of = 0.030779%)

361/50 =~ 7 1/4 (if you admit an error of 0.415513%)
