B) 2
C) 1
D) 0

Answers

Answer 1

Answer: It's a quadratic curve that has a y-intervept below the x axis. Therefore it crosses 2 times

Write in slope intercept form an equation of the line that passes through these given points (-1,-1) (1,5)

Answers

Final answer: Y=3x+2
Since you are given 2 points. You will plug the points into this formula. X2-X1/Y2-Y1. This will get you your slope. Then you will plug one of the points given and your slope into point slope form. This form is Y-Y1=m(X-X1). Then you to get your final answer you want to get Y to be by itself.

Your problem:
5-(-1)/1-(-1)
5+1/1+1
=6/2 =3
m=3

Y-(-1)=3(X-(-1))
Y+1=3(X+1)
Y+1=3X+3
Y=3X+2

What's pathagrium theory

Answers

The correct term is "Pythagorean theorem," not "Patagium theory." The Pythagorean theorem is a fundamental concept in mathematics that relates to right triangles.

It states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.

For example, consider a right triangle with side lengths of 3 units and 4 units. We can use the Pythagorean theorem to find the length of the hypotenuse:

a² + b²= c²

3² + 4² = c²

9 + 16 = c²

25 = c²

Taking the square root of both sides gives us:

c = √25

c = 5

So, the length of the hypotenuse is 5 units.

The Pythagorean theorem has many practical applications, such as in architecture, engineering, and navigation. It is a fundamental concept in geometry and is often used as a building block for more advanced mathematical concepts.

#SPJ6

the pythagorean theorem has to do with right angled triangles -> $a^(2)$ + $b^(2)$ = $c^(2)$ , where c is the hypotenuse length (the longest side, not touching the right angle) and a & b are the other sides that do touch the right angle, the legs.

Simplify the sum. (2u^3 + 6u^2 + 3) + (2u^3 - 7u + 6)

Answers

Steps:

1) Group the like terms and simplify.

2) Do follow the BODMAS Rule. Simplify terms inside the brackets, first. Then, follow this serial: Division, Multiplication, Addition, Subtraction.

Method:

$(2u^3 + 6u^2 + 3) + (2u^3 - 7u + 6)$

= $2u^3 + 6u^2 + 3 + 2u^3 - 7u + 6$

= $2u^3+2u^3+6u^2-7u+3+6$

= $(2u^3+2u^3)+6u^2-7u+(3+6)$

= $4u^3+6u^2-7u+9$

Jose has an employer-sponsored 401(k) plan that he contributes to, and his employer matches 25% of his contributions. Jose's salary is $50,000, and last year he contributed $6000 to his 401(k) plan. What was the total amount that was contributed to his 401(k) last year?

Answers

Given:
50,000 salary
6,000 401K plan contribution of the employee
25% of employee's contribution is the 401K plan contribution of the employer.

6,000 x 25% = 1,500 employer's contribution
6,000 + 1,500 = 7,500

The total amount that was contributed to Jose's 401K plan last year was 7,500.

. Allison drew a triangle with 2 congruent sides and 1 obtuse angle. Which terms accurately describe the triangle? Select all that apply.

Answers

Answer:

obtuse triangle

isosceles triangle

Step-by-step explanation:

A triangle is a three-sided polygon with three edges and three vertices. the sum of angles in a triangle is 180 degrees

Area of a triangle = 1/2 x base x height

the perimeter of a triangle = sum of the side lengths

An isosceles triangle has two opposite sides. If the two angles are equal , it means the triangle is an isosceles. Because 90 degrees is greater than 45 degrees, the two sides with the same length, would have a smaller length than the third side.

Answer:

obtuse triangle

isosceles triangle

Step-by-step explanation:

hope it helps
