Answer:
y = -1/8 x² + 5
Step-by-step explanation:
Parabola opens vertically and vertex (h,k) = (0,5), pass point (4,3)
basic formula: y = a(x - h)² + k
y = a (x-0)² + 5
y = ax² + 5 pass (4,3)
3 = 16a + 5
a = (3-5)/16 = -1/8
equation: y = -1/8 x² + 5
check: pass another point (-4,3)
-1/8 * (-4)² + 5 = -2 + 5 = 3
Answer:
10^12.
Step-by-step explanation:
You need to solve 10^6 * 10^2 without using standard notation. As with variables, if you had x^6 * x^2 you would add the exponents. Replace x with 10. Your answer is 10^8. As a sidenote, only multiply exponents when raising a power to another power, e.g. (10^6)^2 = 10^12.
Answer:
a=3,b=0,c=5,d=-4/21
Step-by-step explanation:
The formule we use to get the slope is:
m = 
a. (3,2);(4,x); m=1
→ x= (1)(4-3)+2 → 3
b. (b,-1);(2,-2); m=-1/2
→ -1= (
)(2-b) → 
→ 0
c. (5,d);(9,2); m=-3/4
→ d= (
)(9-5)-2 → 5
d. (-1/3,3/4);(h,5/6); m=7/12
→ 
= 
(
) → 
We get this equation with the original one:
y=mx+b
There are three forms of linear equations:
point-slope form y2-y1=m(x2-x1)
standard form Ax + By + C = 0 or Ax + By = C
and slope-intercept form y=mx+b
