The area of a triangle is base * height / 2
The length of the base is 16 - 12 = 4
The height is 31 - 0 =0
Then the area is 4*31/2 = 62
Answer= x^4 - 3x^3 - 3x^2 + 7x +6
1. Write out the 0s
(x + 1)(x + 1)(x - 2)(x - 3)
[[ remember the sign flips ]]
2. Foil the first two.
(x + 1)(x + 1)
x^2 + x + x + 1
x^2 + 2x + 1
3. Foil the second two.
(x - 2)(x - 3)
x^2 - 3x - 2x + 6
x^2 - 5x + 6
4. Foil both polynomials.
(x^2 + 2x + 1) (x^2 - 5x + 6)
..
It comes out as:
x^4 - 3x^3 - 3x^2 + 7x +6
You can check the pic for the work on that.
If you want, check your work by finding the 0s. They should be -1, 2, and 3. Also make sure the highest power is the number of 0s.
The highest power is ^4, and there are 4 zeros (since -1 is mult of 2)
Answer: 20.4 feet
Step-by-step explanation:
(image attached for reference)
To find how high the ladder reaches on the wall, first find the relationship between the angle and the wall. The wall is opposite to the angle, so it's possible to solve this equation using sin(58). Sine equals opposite over hypotenuse so sin(58) = x/24. Multiply 24 on both sides to get an equation that can be plugged into a calculator of 24sin(58) = x.
24sin(58) = 20.35, which gets rounded up to a final answer of 20.4 feet.
Answer:
.69, but you can round it to .70 because of the 9
