Answer:
Step-by-step explanation:
the two ends , made up of triangles make an 8x5x5 box1
box1 = 200
the center piece makes a box2 of 10x8x5
box2 = 400
volume = 600
Answer:
-62.8 is the answer .......................
Answer:
By doing it myself, i'm not entirely sure, but I got answer C. Sorry if it's not right.
Step-by-step explanation:
Well since we know the roots are x = 5 and x = -1/4. We can convert it into an equation and make it equal to 0.
Simply work backwards instead of solving for x. For x = 5, it would be x - 5 = 0, because if you solve for x it will be 5.
Same thing for x = -1/4, the equation would be x + 1/4 = 0.
(X-5)(x+1/4) = 0.
Now multiply the 2 binomials together to get the quadratic. To get rid of the fraction after obtaining the quadratic multiply by 4 for each term in the quadratic.

Step-by-step explanation:
Since Point A is included in the altitude, we must have an equation that has to make Point A a solution set in the equation.
Pluging in and chugging Point A into each equation should tell us what the equation should be.
<u>Option 1</u>
x - y = 1
-3 - 2 = 1
-5 ≠ 1
We see here that -5 does not equal to 1. Therefore option 1 is incorrect.
<u>Option 2</u>
x + y = -1
-3 + 2 = -1
-1 = -1
We see here that -1 does equal to -1. Therefore option 2 is correct.
<u>Option 3</u>
x + y = 1
-3 + 2 = 1
-1 ≠ 1
We see here that -1 does not equal to 1. Therefore option 3 is incorrect.
<u>Option 4</u>
x - y = -1
-3 - 2 = -1
-5 ≠ -1
We see here that -5 does not equal to 1. Therefore option 4 is incorrect.
We can also graph the points and eyeball it. Doing so, we should see that our y-intercept is around -1 and our slope is also negative. Option 2 would be the best fit.
