Answer:
343,000
Step-by-step explanation:
Imagine there are a bunch of zeros to the right of the thousandths decimal place. If the 10 is raised to the fifth power, you want to move the decimal place to the right 5 times. This makes the new number 343,000. Since there are only 3 sig figs in the original number, there would be no decimal place in the standard form.
The equation of a circle is (x-h)²+(y-k)²=r², with h being the x value in the center, k being the y value, and r being the radius. Plugging them in, we get
(x-6)²+(y-(-2))²=(1/5)²
= 1/25
= (x-6)²+(y+2)²
Answer: The height of the mountain is 1,331.4 meters (approximately)
Step-by-step explanation: From the information given, the students were standing at point b which is 800 meters from the base of the mountain and the angle of elevation from that point is 59°. Assuming that the ground is level, we can derive a right angled triangle from this set of details and hence we have triangle ABC, where angle β is the reference angle, (59 degrees), BC is the distance from the students to the base of the mountain (800 meters) and the line AC is the height of the mountain.
The line AC is the opposite, since angle B is the reference angle, therefore we shall use the trigonometric ratio as follows;
Tan β = opposite/adjacent
Tan 59 = AC/800
Tan 59 x 800 = AC
1.6643 x 800 = AC
1331.44 = AC
AC ≈ 1331.4
Therefore the height of the mountain is approximately 1,331.4 meters

Answer:
- yes
- 5 × (6 - 3) = (5 × 6) - (5 × 3)
Step-by-step explanation:
The distributive property tells you the factor outside parentheses multiplies each of the terms inside parentheses.
The difference 6 -3 inside parentheses has two terms, and there is a factor of 5 outside those parentheses. The setup for the distributive property is there, so the distributive property can be used.
__
The outside factor multiplies each inside term. The sign can be left with the inside term, or can be placed between the products.
5 × (6 - 3) = (5×6) - (5×3)
__
or
5 × (6 - 3) = (5×6) +(5×(-3))
