If 100c^2 has a value of 4950 what is the value of 100c98

Mathematics

Answer:

100(49.5)^{49}

Step-by-step explanation:

Let's solve 100c^2=4950

Divide both sides by 100:

c^2=49.5

Take the square root of both sides:

c=\sqrt{49.5} (I did not keep the negative value because it doesn't matter since we are only considering even powers of c.)

So now let's plug it into:

100c^{98}

100(\sqrt{49.5})^{98}

100(49.5)^{49}

How do I solve 2x+3y=7, x-y=1
Fittoniya [83]
<span>2x+3y=7
x-y=1

</span>2x+3y=7
x=1+y

2*(1+y)+3y=7
x=1+y

2+2y+3y=7
x=1+y

5y=5       |(:5)
x=1+y

y=1
x=2

CHECK:
2x+3y=7
x-y=1

2*2 + 3*1 = 7     

x-y = 1
2-1 = 1

I need help with numbers 20,21,and22
julsineya [31]

Answer:

20) the answer is -43

21) the answer is 25

22)the answer is -5

Step-by-step explanation:

20) \frac{p(p+n^{2})}{6}

n=-7

p=-6

we have:

\frac{-6*(-6+(-7)^{2})}{6}\\\\\frac{-6*(-6+49)}{6}\\\\\frac{-6*(43)}{6}\\\\\frac{-258}{6} \\-43

21) mp-(p-(m-n))

m= -1     n=-6   p=-10

-1*-10-(-10-(-1-(-6)))

10-(-10-(5))

10-(-15)

10+15=25

22) m-\frac{m+m}{2} - n

m=1   n=5

1- \frac{1+1}{2} -5

1- 2/2 -5

1-1-5 =-5
