Answer:
C. -1/2
Step-by-step explanation:
(-2,2)
(0,1)
(2,0)
Change in y = -1
Change in x = 2
Equation: y = -1/2x + 1
The area formula is length times width, and since the length is 17 cm in this case, 17 times width = 102, so we must divide 102 divided by 17, and you will get 6. The perimeter formula is 2 times the length plus 2 times the width, so
2(17) + 2(6), which gives us 46, so the perimiter is 46.
The circumference of the tire would be: 28 x PI = 87.96 inches = 88 inches.
88 inches / 12 inches = 7.33 feet
Every revolution the tire would travel 7.33 feet.
1 mile = 5,280 feet
3 miles = 5280 x 3 = 15,840 feet total.
Divide total feet by the circumference of the tire:
15,840 / 7.33 = 2,161 revolutions.
The 2 legs of the triangle below are a and b. The 2 legs are called the opposite and adjacent sides respectively. The side c is called the hypotenus. The hypotenus side is the longest side of a right angle triangle.
No, not at all.
The general quadratic equation is
Ax² + Bx + C = 0 .
The roots are real only if (B² - 4AC) is not negative.
That means if you graph it, it touches or crosses the x-axis.
If the graph is up in the air and never touches the x-axis,
then it has no real roots.
