The baby will weigh approximately 14.18 pounds after 6 months of birth.

Step-by-step explanation:

Step 1; The baby weighed 7 pounds when it was born and started gaining weight after the fourth day. We need to find the baby's weight 25 weeks after he's born. Since he only gains weight from the 5th day, we need to find the weight he gained in 24 weeks but we need to know his weight in the 25th week we need to calculate his weight in the 23rd week.

Step 2; If the baby gains 5 ounces a week, it will gain 23 times that 5 ounces after 23 weeks.

Weight gained in 23 weeks = 23 weeks × 5 ounces a week = 115 ounces.

By converting ounces into pounds, 115 ounces = 7.1875 pounds.

So the baby's weight in the 25th week = 7 + 7.1875 = 14.1875 pounds.

-3x+3y=12

Answer:

C

Step-by-step explanation:

  1. Reform the first graph: -3x + 3y = 12; 3y = 12 + 3x; y = 4 + x; y = x + 4
  2. Compare y = x + 4 and y = x + 4: they are equal, thus the same slope (1) and the same y-intercept (4)

Solve in radians help plz
PIT_PIT [208]
I think we can use the identity  sin x/2  = sqrt [(1 - cos x) /2]

cos x -  sqrt3 sqrt ( 1 - cos x) /sqrt2 = 1

cos x - sqrt(3/2) sqrt(1 - cos x) = 1
sqrt(3/2)(sqrt(1 - cos x) =  cos x - 1   Squaring both sides:-
1.5 ( 1 - cos x) = cos^2 x - 2 cos x + 1

cos^2 x - 0.5 cos x - 0.5 = 0 

cos x = 1 , -0.5

giving x = 0 , 2pi, 2pi/3,  4pi/3  ( for  0  =< x <= 2pi)

because of thw square roots some of these solutions may be extraneous so we should plug these into the original equations to see if they fit.

The last 2 results dont fit so the answer is  x = 0 , 2pi Answer

4x + 1/3y^2
Romashka-Z-Leto [24]
1.) Plug x and y to the formula:

4(2) + 1/3(3)^2

2.) Simplify

8 + 1/3(9)

= 8 + 3

= 11


Hope this helped!!!
