Answer:
y = -3x^2 -9x +30
Step-by-step explanation:
When a polynomial has a zero at x=p, it has a factor of (x -p). The factors of your quadratic are ...
f(x) = (x +5)(x -2)
At the point x=3, the value of this product is ...
f(3) = (3 +5)(3 -2) = (8)(1) = 8
In order for that value to be -24, it needs to be multiplied by a scale factor of -3. The quadratic you want is ...
y = -3(x +5)(x -2)
y = -3x^2 -9x +30 . . . . . standard form
Use the Pythagoras Theorem in the corresponding right angled triangles.
Answer:
20 cans
Step-by-step explanation:
Eileen collected 78 empty cans to recycle
Carl collected 62 empty cans to recycle
They pack equal number of cans in 7 boxes
Therefore the number of cans in each boxes can be calculated as follows.
= 62 + 78/7
= 140/7
= 20
Hence there were 20 cans in each boxes
You would do 11 times 8 because you need all the legs of the spiders.
So, there would be 88 spider legs. 88 would be your answer.
Answer:
83.333333π
Step-by-step explanation:
the volume of a cone is (1/3) · π · r^2 · h, so 1/3 times pi times 5^2 times 10
which is 83.3pi, or 261.7
