A)
Vf² = vi² + 2ad Subtract 2ad from both sides
Vf² - 2ad = vi² Find the square roots of both sides
√(Vf² - 2ad) = √(vi²) Cancel out the squares with the square roots
Vf - √(2ad) = vi Switch the sides to make it easier to read
vi = Vf - √(2ad)
B) Vf² = vi² + 2ad Subtract vi² from both sides
Vf² - vi² = 2ad Divide both sides by 2a
(Vf² - vi²) / 2a = d Switch the sdies to make it easier to read
d = (Vf² - vi²) / 2a
I'll help with a few because no-one wants to just do your homework
there is the formula way or the intuitive way
(-19, -2) (-17, -10)
now slope is (difference in y)/ (difference in x)
or
(y2 - y1)/(x2 - x1) the formula. where x2 just means the second x
<u>formula way:</u>
(-19, -2) (-17, -10)
(-10 - (-2))/ (-17 - (-19)) ReM: Negative on number and in the formula
(-10 + 2)/ (-17 +19) = -8/2 slope is - 8/2
<u>intuitive way</u>
(-19, -2) (-17, -10)
(difference in y)/ (difference in x)
lets looks at the ys
-2 and -10; how many steps from -2 to -10? -8 the diff in y
lets looks at the xs
-19 to -17; how many steps from -19 to -17? + 2 the diff in x
so its -8/2
In order to figure this out, we can set up a proportion and simplify using cross multiplication.
One grapefruit costs
89 cents.
Answer:
.50 for one donut
Step-by-step explanation:
do a ratio 6$ for 12 donuts
so for $ for 1 donut
reduce the first equation for a ration of $1 per two donuts
so it be 50 cents
we know that
if two lines are parallel
then
their slopes are equal
Step 1
Find the slope of the line 2x + 5y = 4
2x + 5y = 4------> 5y=4-2x-----> y=(4/5)-(2/5)x------> slope m=(-2/5)
step 2
with m=-2/5 and the point (5, –4) find the equation of the line
y-y1=m*(x-x1)------> y+4=(-2/5)*(x-5)----> y=(-2/5)x+2-4
y=(-2/5)x-2
therefore
the answer is the option D
