Answer:6.37
Step-by-step explanation:
f(x)= −0.07x²+ 0.42x+ 6.37
1. Find the x-coordinate. x= -(b/2a)
= -(0.42/-0.07) = 6
x=6
2. Find the corresponding y-coordinate.
f(x)= −0.07x²+ 0.42x+ 6.37
substitute x with 6
-0.07(6)²+0.42(6)+6.37
Simplify
-2.52+2.52+6.37=
6.37
Orthocenter would be the answer for anything with altitudes
The value is 10 because 10*43.50 equals 435
Answer:
6.6×10²¹
Step-by-step explanation:
6,600,000,000,000,000,000,000 → there are 21 place values after the first non-zero number ''6''
to convert to standard form, we move the decimal point after the first non-zero number.
<em>6,600,000,000,000,000,000,000</em><em>.</em><em>0 ← decimal in the end</em>
<em>the decimal </em>will be moved, all the digits after the decimal are counted and they will resemble the index.
6.6×10²¹
3x - 2y = 6
-2y = -3x + 6
y = 3/2x - 3.....the slope here is 3/2. A parallel line will have the same slope.
so ur answer is : y = 3/2x + 4...because the slope here is 3/2
