Mathematics
1 answer:
kakasveta [241]3 years ago

Answer:

11. B

12. D

Step-by-step explanation:

11)

2 times 10⁻² = 2·0.01 = 0.02 ≈ 0.0201

12)

6·10⁻⁴ = 6·0.0001 = 0.0006

However, 0.00058 rounds to 0.0006 and 0.00067 rounds to 0.0007, so the answer is a better estimation for D than for B.

What is the lateral area of the rectangular prism? Assume the prism is resting on its base.
garri49 [273]
<span>A rectangular prism has four lateral surfaces. If the sides of the base are L and W, two of the lateral surfaces are rectangles of side L and H, and the other two are rectangles of sides W and H. Then, the lateral area is the sum of the areas of the four lateral rectangles: 2 * L * H + 2 * W * H= 10 * 4 = 2 * 10 * 4 + 2 * 5 * 4 = 2*40 + 2 * 20 = 80 + 40 = 120.</span>

Solving Exponential and Logarithmic Equation In exercise,solve for x or t.See example 5 and 6.
Virty [35]

Answer:

x=\frac{6e^3}{e^3-1}

Step-by-step explanation:

ln x - ln(x - 6) = 3

Apply natural log property

ln mn=ln m + ln(n), ln(m/n)=ln(m)-ln(n)

ln x - ln(x - 6) = 3

ln(\frac{x}{x-6} )=3

All natural log has base 'e'

\frac{x}{x-6} =e^3

cross multiply

x=e^3(x-6)

x=e^3x-6e^3

add 6e^3 on both sides and -x on both sides

6e^3=e^3x-x

6e^3=x(e^3-1)

Divide e^3-1 on both sides

x=\frac{6e^3}{e^3-1}

10x10x10=1000 V

Put the 1000 within the problem.

2 x 1000

Solve

2 x 1000 = 2000 Visitors

7 days are within a week so multiply the daily visitors (2000) by 7

2000 x 7 = 14,000


Answer: 14,000 visitors weekly
