Answer: both ways are acceptable
Step-by-step explanation: When writing equations of lines in this form,
we usually keep the "b" value or the constant term as a fraction.
However, if you prefer decimals, you can absolutely change
it to a decimal to visualize is better if you'd like, it's really your choice.
For example, if the equation of a line was y = -3/4x - 7/4, I could leave
it how it is or I could change the -7/4 to -1.75 giving me y = -3/4x - 1.75.
Answer:
Step-by-step explanation:
Not QUITE a parabola . but up until y = 4 it is close
Vertex = (-7-10)
Vertex form of parabola
y = a ( x+7)^2 -10 find a integer-coordinat point to calculate 'a'
I'll use -18,0
0 = a(-18+7)^2 -10
0 = 122 a -10 a = 10/122
y = 10/122 (x+7)^2 - 10 see graph below:
Answer:
A: 1/2 divided by 1 1/2 is 3. 1/2 divided by 1 is 2. 1/2 divided by 2 1/2 5. Multiply those numbers and you get 15 which is how many can fit. B: Idk how to answer part B but you can have part A.
Step-by-step explanation:
Length: 1 1/2. Width: 1. Height: 2 1/2. Volume: how much of ? can fit in a ?. To get the volume you multiply 1 1/2 x 2 1/2 x 1. Make the mixed numbers into improper fractions: 3/2, 5/2, 2/2. Now multiply the numerators: 5 x 3 = 15x 2 = 30. Now in order to finish it you put 2 as the denominator. : 30/2 which as a whole number is 15. 15 cubes can fit.
Answer:
1. N/A
2. √V/pi*h= r
Step-by-step explanation:
1. when you try to get r on one side, the r's cancel out
2. V/pi*h= r^2
√V/pi*h= r
