12.38 in expanded form is write like:-
10 + 2 + .3 + .08 = 12.38
To
write a number in expanded form just means to write the number in a
layout and when you add it up it will become the number you needed to
write in expanded form.
So, 12.38 written in expanded form is:- 10 + 2 + .3 + 0.8
Hope i helped
Answer:
Vertex form: f(x) = -10(x − 2)^2 + 3
Standard form: y = -10x^2 + 40x - 37
Step-by-step explanation:
h and k are the vertex coordinates
Substitute them in the vertex form equation:
f(x) = a(x − 2)^2 + 3
Calculate "a" by replacing "f(x)" with -7 and "x" with 1:
-7 = a(1 − 2)^2 + 3
Simplify:
-7 = a(1 − 2)^2 + 3
-7 = a(-1)^2 + 3
-7 = a + 3
-10 = a
Replace a to get the final vertex form equation:
f(x) = -10(x − 2)^2 + 3
Convert to standard form:
y = -10(x − 2)^2 + 3
Expand using binomial theorem:
y = -10(x^2 − 4x + 4) + 3
Simplify:
y = -10x^2 + 40x - 40 + 3
y = -10x^2 + 40x - 37
Answer:
22
Step-by-step explanation:
x + 90 + 68 = 180
x + 158 = 180
x = 22
Answer:
<h2>510</h2><h2 />
Step-by-step explanation:
30-22=8
22-14=8
14-6=8
then
→ the common difference r = 8
→ the first term = 6
THerefore, (accoriding to the standard explicit formula)
the 64th term = term 1 + (64 - 1)×r
= 6 + 63×8
= 510
