Answer:
Total Area: 60
Step-by-step explanation:
The area of the rectangle is the easiest to find. Just multiply 12x4.
12x4=48
For the triangle. You can subtract 4 from the height of 10ft.
The height of the triangle is now 6ft.
To calculate the area of a triangle, multiply the height by the base (this is also known as the 'width') then divide by 2.
Btw the image was really small. Kind of hard to see the numbers.
8 meters per second. You get this by dividing the amount of meters by the amount of seconds. 200/25=8.
A = (2x + 4)(x^2 - 2)
A = 2x(x^2) + 2x(-2) + 4(x^2) + 4(-2)
A = 2x^3 + -4x + 4x^2 + -8
A = 2x^3 + 4x^2 - 4x - 8
Hope this helps!! :)
10 x 8 = 80ft for the rectangle
To work out the area of the semi circle you do pi (3.14) x the radius squared, the radius is half the diameter.
3.14 x 4 squared
3.14 x16 = 50.24ftsqaured for the whole circle so you divide it by 2 which is 25.12ft squared.
And then finally you add 25.12 and 80 so your answer is 105.12 ft squared
3x-7y-14 = 0
7y = 3x-14
y = (3/7)x - 2
slope of perpendicular line = -1/(3/7) = -7/3
so function f which is perpendicular and has same y-intercept is
y = (-7/3)x - 2
