(-4)(-2)= 8
8(-5)= -40
Answer: -40
Answer:
see below
Step-by-step explanation:
Eric will drive between 70 -4 = 66 mph and 70+4 = 74 mph. He will <em>not</em> drive less than 66 or more than 74 mph.
A
this is a geometric sequence since there exists a common ratio r between the terms
r = = = = 3
B
to obtain the next term in the sequence multiply the previous term by 3
= 3 ← recursive rule
C
the n th term of a geometric sequence is
=
where is the first term in the sequence
= 7 × ← explicit rule
P = k/w^2
<span>first of all you need to find k </span>
<span>But I kind of don't like the units of each value so let say </span>
<span>400KPa = 4 * 10^5 Pa = 4 * 10^5 N/m^2 </span>
<span>2 cm = 2 * 10^-2 m </span>
<span>input values in the equation </span>
<span>4*10^5 = k/(4*10^-4) >>> k = 160 N </span>
<span>P = 160/w^2 </span>
<span>it said if she wears a heel with a width of .5 cm </span>
<span>P = 160(0.5 * 10^-2)^2 >>> P = 6400 KPa</span>
