Answer:
<em>y=17</em>
Step-by-step explanation:
<u>System of Equations</u>
We have an explicit equation for x and y
The other equation will have to be created by using the data in the table. We only need two points from the table, let's pick (-3,-9) and (-1,-5). The equation can be found by using the formula
Let's plug in the given points
Simplifying and rearranging:
The other equation forms the system
Multiplying the first equation by 3 and the second by -2
Adding both equations
The value of x is
To solve this problem, we need to know the formulas for the areas of each of these shapes. The formula for the area of a circle is πr², the area of a rectangle is b * h, the area for a square is s², and the area for a triangle is 0.5bh. Now we can solve.
1) This is a circle, so the area is πr² = π(6)² = 36<span>π square feet
2) This is a square, so the area is s</span>² = 12² = 144 square yards
3) This is a rectangle, so the area is b * h = 6 * 14 = 84 square inches
4) This is a rectangle, so the area is b * h = 7 * 3 = 21 square inches
5) This is a circle, so the area is πr² = π(4)² = 16<span>π square feet
6) This is a triangle, so the area is 0.5bh = 0.5 (8 * 8) = 0.5 * 64 = 32 yd.</span>²
7) This is a triangle, so the area is 0.5bh = 0.5 (5 * 10) = 50 * 0.5 = 25 yd.²
8) This is a rectangle, so the area is b * h = 10 * 2 = 20 in²
9) This is a square, so the area is s² = 9² = 81 ft²
Answer: We can get all of the answers by looking at the parts of the graph.
1) The height of the board is about 10, that is all the way at the left.
2) The maximum height is 10.8 at the vertex of the graph.
3) The time at the vertex is 0.4 seconds.
4) The diver enters the water after 1.9 seconds, it is at the bottom right.
U check it by multiplying the dividend
0 is neither prime or composite along with the number 1.
