Answer: 22 weeks
he would have to work 22 weeks to earn enough money.
15 * 22 = 330
330 + 35 = 365
(1 point) Let pp be the quartic (degree 4) polynomial that satisfies p(i)=2i,i=0,1,2,3,4. p(i)=2i,i=0,1,2,3,4. Then p(x)=p(x)= .

Answer:
a = 1/3
b = -3
c = 26/3
d = -6
e = 0
Step-by-step explanation:
Given the quartic polynomial
p(x)=ax⁴+bx³+cx²+dx+e and
p(i) =2i when i=0,1,2,3,4
If i = 0:
p(0) = 2(0)
p(0) = 0
0 = 0+0+0+0+0++e
e = 0
When i = 1
p(1) = 2(1) = 2
2 = a(1)⁴+b(1)³+c(1)²+d(1)+e
2 = a+b+c+d+0
a+b+c+d = 0... (1)
When i = 2, p(2) = 2(2)
p(2) = 4
4 = a(2)⁴+b(2)³+c(2)²+d(2)+e
4 = 16a+8b+4c+2d+0
16a+8b+4c+2d = 4
8a+4b+2c+d = 2... (2)
When i = 3
p(3) = 8
8 = a(3)⁴+b(3)³+c(3)²+d(3)+0
8 = 81a+27b+9c+3d..(3)
When i = 4
p(4) =16
16 = a(4)⁴+b(4)³+c(4)²+d(4)+0
16 = 256a+64b+16c+4d
64a+16b+4c+d = 4...(4)

Answer:
5
Step-by-step explanation:
640 divided by 4 is 160 so 800 divided by 160 equals 5
Answer:
<em>x > 2
</em>
<em>x ∈ ( +2 ; + oo )</em>
Step-by-step explanation:
<em>8 - 2x < 4
</em>
<em>8 - 4 < 2x
</em>
<em>4 < 2x | : 2
</em>
<em>2 < x
</em>
<em>
</em>
<em>x > 2
</em>
<em>x ∈ ( +2 ; + oo )</em>
