. A right triangle has one leg with a length of two. Give an example of possible lengths for the other leg and the hypotenuse.

Answers

Answer:

For the other leg = 1 unit, the hypotenuse will be = units.

For the other leg = 2 unit, the hypotenuse will be = units.

Step-by-step explanation:

A right triangle has one leg with a length of 2 units.

Now we have to give examples of the possible length of the other leg and the hypotenuse.

The length of the other leg does not depend on the given leg length of 2 units.

So, it maybe 1 unit or 2 units or any value.

If the other leg is 1 unit, then the length of the hypotenuse will be (Applying Pythagoras Theorem) = units.

If the other leg is 2 units, then the length of the hypotenuse will be = units.

And hence, we will get a distinct length of hypotenuse for each length of the other leg. (Answer)

Determine the slope and y-intercept from the following equation: 4x + y = -10 Question 9 options:

slope: 4 y-intercept: (0,10)

slope: -4 y-intercept: (0,10)

slope: -4 y-intercept: (0,-10)

slope: 4 y-interce

Answers

Answer:

Answer D: Slope: 4 y-intercept: -10

Step-by-step explanation:

The answer is D because in the slope-intercept equation(y=mx+b) m=slope and b=y-intercept. This equation is not in the correct order but the slope is 4 because it is where the m would be and it's next to the x. The y-intercept is -10 because it's where the b would be in this equation, it's by itself, and you can see the y separate from any numbers.

What is the solution (x, y) to the system of equations shown? 2y + x = −17
5x − 4y = −15

A) (−7, −5)
B) (−4, −1)
C) (−3, 0)
D) (5, −11)

Answers

Answer:

x=-7, y=-5. (-7, -5).

Step-by-step explanation:

2y+x=-17

5x-4y=-15

---------------

x=-17-2y

5(-17-2y)-4y=-15

-85-10y-4y=-15

-85-14y=-15

14y=-85-(-15)

14y=-85+15

14y=-70

y=-70/14

y=-5

2(-5)+x=-17

-10+x=-17

x=-17-(-10)

x=-17+10

x=-7

A sailboat set a course of N 23° E from a small port along a shoreline that runs north and south. Sometime later the boat overturned and the crew sent out a distress call. They estimated that they were 11 miles away from the nearest harbor, which is 28 miles north of the port they had set sail from. If a rescue team leaves from the harbor, find all possible courses the team must follow in order to reach the overturned sailboat. (Select all that apply.) A.) S 73° E

A sheet of paper 90 cm-by-66 cm is made into an open box (i.e. there's no top), by cutting x-cm squares out of each corner and folding up the sides. Find the value of x that maximizes the volume of the box. Give your answer in the simplified radical form. x =?? is the max.

Answers

The value of x that maximizes the volume of the box is:

The dimension of the paper is given as:

When the cut-out (x) is removed, we have:

So, the volume is:

This gives

{HH,CC,HC,CH}

Step-by-step explanation:

We are given that

H denotes hot and cloudy denotes C.

We have to find the total possible outcomes for the weather on two consecutive days.

The possible cases in two consecutive days

Both days are hot=HH

Both days are cloud=CC

First day is hot other day cloudy=HC

First day is cloudy other day is hot=CH

Total possible cases=HH,CC,HC,CH

Therefor, the total outcomes for the weather on two consecutive days={HH,CC,HC,CH}

What is an equation of the line that passes through the points (6,-5) and (3,0)

Answers

Answer:

y+5=-5/3(x-6)

Step-by-step explanation:

y-y1=m(x-x1)

m=(y2-y1)/(x2-x1)

m=(0-(-5))/(3-6)

m=(0+5)/-3

m=5/-3

m=-5/3

y-(-5)=-5/3(x-6)

y+5=-5/3(x-6)

Gradient = (-5-0) / (6-3)
= -5 / 3
y-intercept = -5 - 6 * (-5/3)
= -5 - ( -10 )
= 5

Equation: y = -5/3 x + 5
