Let f(x)=ax+b
11a+b=23.55
12a+b=25.35
solve: a=1.8 b=3.75
so ..
f(x)=1.8x+3.75
if x=31 , f(x)=59.55
<span>0.000938 in scientific notion.
First we need to move the decimal to its right and we need a number which is between 1-10.
0.000938
00.00938
000.0938
0000.938
00009.38
We moved the decimal 4 times and to the right so it will be negative. -4.
9.38 </span>× 10^-4
Scientific notation of 0.000938 is 9.38 × 10^-4.
Check:-
9.38 × 10^-4 = <span>0.000938
</span>0.000938 = <span>0.000938
</span>Correct!
<span>Scientific notation of 0.000938 is 9.38 × 10^-4.</span>
Answer:
(x - 2)(x + 2)
Step-by-step explanation:
x² - 4 ← is a difference of squares and factors in general as
a² - b² = (a - b)(a + b), that is a product of two binomials
Given
x² - 4
= x² - 2²
= (x - 2)(x + 2)
Answer:
Step-by-step explanation:
In school i did these but i have no clue how to do them.I will try though:)
Answer:
Component form : (-7 , 2)
Step-by-step explanation:
P(4 , 5) = P'(4 +x , 5+y) = P'(-3 , 7)
4 + x = -3
x = -3 - 4
x = -7
5 + y = 7
y = 7 - 5
y = 2
Vector form : -7i + 2j
Component form : (-7 , 2)
