Marco and Suzi each multiplied 0.721 x 100 (it’s actually 10 to the second power but i don’t think they have anything like that

on the keyboard so i wrote 100). Marco got 7.21 for his product. Suzi got 72.1 for her product. Which student multiplied correctly? How do you know?

Answer:

Suzi did

Step-by-step explanation:

Yes they do have 10^2 power on your calculator.

Look for the ^ key or Exp or y^x or x^y. Most scientific calculators have one of those.

Suzi did it correctly. 0.721 * 100 is a decimal move two places to the right. That would bring the decimal between the 2 and the 1.

At 3pm, the length of the shadow of a thin vertical pole standing on level ground is the same as the height of the pole. A while
aliya0001 [1]

Answer: The height of the pole is 175.97 ( approx )

Step-by-step explanation:

Let the height of the pole is x cm,

Also, let the angle of elevation of the sun to the pole at 3 pm is \theta

Thus, by the question,

tan\theta = \frac{\text{ The height of the pole}}{\text{ The height of the shadow}}

\implies tan\theta = \frac{x}{x}    ( at 3pm the height of shadow = height of the pole)

\implies tan\theta = 1

\implies \theta = 45^{\circ}

Again, according to the question,

When the angle of elevation is   (\theta - 12^{\circ}),

The height of shadow = x + 95,

\implies tan(45-12)^{\circ}=\frac{x}{x+95}

\implies tan 33^{\circ}=\frac{x}{x+95}

\implies tan 33^{\circ}x + 95\times tan33^{\circ}=x

\implies tan 33^{\circ}x - x = - 95\times tan33^{\circ}

\implies -0.3505924068 x = - 61.6937213538

x=175.969930202\approx 175.97\text{ cm}

(-3,0);slope=2/3 slope intercept form
Step2247 [10]
Y = mx + b, m = slope and b = y-intercept

Because you don't have the y-intercept, you take the equation and replace x and y with the values given, then solve for b and replace b in the original equation with the value found.

y = 2/3x + b
0 = (2/3)(-3) + b
0 = -2 + b
2 = b

y = 2/3x + 2 is the answer
