The present shown below is a cube. Find the surface area.
vitfil [10]

Answer:

SA = 2,400 cm²

Step-by-step explanation:

Surface Area (SA) of a cuboid: 2(lw) + 2(wh) + 2(hl)

SA = 2(lw) + 2(wh) + 2(hl)

  • l = 20 cm
  • w = 20 cm
  • h = 20 cm

Substitute the values above and multiply:

SA = 2(lw) + 2(wh) + 2(hl)

SA = 2(20)(20) + 2(20)(20) + 2(20)(20)

SA = 2(400) + 2(400) + 2(400)

SA = 800 + 800 + 800

SA = 2,400 cm²

Final answer: 2,400 cm²

Hope this helps!

Jerome takes a math course and a science course for summer school. For every 4 hours jerome spends studying math, he studies sci
scoray [572]

Answer:

8 hours for math and science each

Step-by-step explanation:

4 x 8 = 32

3 x 8 = 24

32 + 24 = 56 hours

- You need to keep what you multiply, (ex. 8), the same as you work through this problem.

- Such as this problem, sometime the best methods are to just guess and check. This means to think of a number that is reasonable and try it. For example, if you try 5 and you see it is too low, go higher. Keep doing this and you would have got to 8 eventually.

Use Newton's method to approximate a root of the equation 3x^(7) + 2x^(4) + 2 = 0 as follows. Let x1 = 3 be the initial approxim
Maurinko [17]

Answer:

x_{2}\approx 2.59, x_{4}\approx 4.3

Step-by-step explanation:

1) Given that the formula for the Newton Method is:

x_{n+1}=x_{n}-\frac{f(x_{n})}{f(x_{n+1})}

2) The Function and its 1st derivative

f(x)=3x^{7}+2x^{4}+2\\f'(x)=21x^{6}+8x^{3}

3) Let's work with the first approximation. Plugging in in the function:

f(x)=3x^{7}+2x^{4}+2\Rightarrow f(3)=3(3)^{7}+2(3)^{3}+2\Rightarrow f(3)=6617\\f'(x)=21x^{6}+8x^{3}\Rightarrow f'(3)=21(3)^{6}+8(3)^{4}\Rightarrow f'(3)=15957\\\\x_{n+1}=x_{n}-\frac{f(x_{n})}{f'(x_{n})}\Rightarrow x_{2}=x_{1}-\frac{f(x_{1})}{f'(x_{1})}\\x_{2}=3-\frac{6617}{15957}\Rightarrow x_{2}\approx 2.59\\\\

4) To approximate the other root x

f(x)=3x^{7}+2x^{4}+2\Rightarrow f(5)=3(5)^{7}+2(5)^{3}+2\Rightarrow f(5)=234627\\f'(x)=21x^{6}+8x^{3}\Rightarrow f'(5)=21(5)^{6}+8(5)^{4}\Rightarrow f'(5)=333125\\\\x_{n+1}=x_{n}-\frac{f(x_{n})}{f'(x_{n})}\Rightarrow x_{4}=x_{3}-\frac{f(x_{1})}{f'(x_{1})}\\x_{4}=5-\frac{234627}{333125}\Rightarrow x_{4}\approx 4.3
