3x^2+x-4=0
Solve by factoring or using the quadratic formula
Answer:
with the points (2,3) and (-1,-9) the answer is y=4x+10
Step-by-step explanation:
you have to do (x1,y1) (x2,y2) thats for each point
the equation to get the slope is y2-y1 divided by x2,x1
to get the y-intercept to plug in one of the points to the slope-intercept equation
y=4x+5
I picked the points (2,3) but you should get the same answer with the other points
3=4(2)=5
3=8+5
3=13
-3+-3
=10 thats your y intercept.
The rope is tied 4.5 ft from the center of the tent.
Pythagorean theorem states that in the right angle triangle the hypotenuse square is equal to the square of the sum of the other two sides. According to this statement, the areas of the squares on the other two sides add up to the size of the square whose side is the hypotenuse.
The value of c is calculated as:-
a² + b² = c²
It is given the rope is attached to the top of her tent and the rope the camper takes is 6ft long and tied to the ground. A right-angle triangle is formed with hypotenuse as 6 ft and height that one of the legs of the right triangle as 4 ft.
The length of the rope from the ground to the tent will be calculated as below:-
By Pythagoras's Theorem :
a² + b² = c²
4² + b² = 6²
b² = 36 - 16 = 20
b = √20 = 4.47 ft.
Therefore, the rope is tied 4.5 ft from the center of the tent.

Answer:The rope is tied 4.5 ft from the center of the tent.
Step-by-step explanation:
It is given the rope is attached from top of her tent and the rope the camper takes is 6ft long tied to the ground.A right angle triangle is formed with hypotenuse as 6 ft and height that is one of the legs of the right triangle as 4 ft . We need to find the other leg of the right triangle which will represent the ground distance from the middle of tent to the point where the rope is tied .
By Pythagoras's Theorem :
Where a and b are the legs and c the hypotenuse of the right triangle.
Substituting the values of a and c we have:
or
Tabing root of both sides b=4.47.
The rope is tied 4.5 ft from the center of the tent.
Answer:
Option A is correct that is $15.
Step-by-step explanation:
Caroline bought 20 shares of stock at , and after 10 months the value of the stocks was .
We need to calculate the profit which is the difference of the two values of the stock.
The above value is for 1 share we have to calculate it for 20 shares
So, we will multiply it with 20 we get:
Therefore, Option A is correct that is $15.
