Answer:
<em>The actual length of the ship is 337.6 m</em>
<em>The actual width of the ship is 65.6 m</em>
Step-by-step explanation:
<u>Scaling</u>
The scale model of the aircraft carrier USS Eisenhower is 42.2 cm long and 8.2 cm wide when using the scale factor of 1 cm=800 cm.
Since we are required to express the real measures in meters, the scale factor is 1 cm = 8 m.
The actual length of the ship is:
42.2*8=337.6 m
The actual width of the ship is:
8.2*8=65.6 m
The number is 157, because it's 100-200, 10-5=5 (ones place) & 5+2=7 (tenths place)
Answer:
Step-by-step explanation:
- log₄ (m²) = log₄ (18 - 7m)
18 - 7m > 0 ⇒ 7m < 18 ⇒ m < 18/7
- m² = 18 - 7m
- m² + 7m - 18 = 0
- m² + 2*3.5m + 12.25 = 30.25
- (m + 3.5)² = 5.5²
- m = - 3.5 ± 5.5
Answer:
y = -3/4x + 7/4
Step-by-step explanation:
use the boins to find the slope in the equation y2 - y1/x2 - x1
4 - -2/-3 - 5 = 6/-8 or 3/-4
plug that into the equation: y = mx + b
m = slope b = y-intercept
y = 3/-4x + b now plug in one of the points ex) (5, -2)
(-2) = 3/-4 (5) + b now solve to find the y-intercept: B
b=7/4
now to check your answer plug the other point into the original equation (I have already done this the y-intercept is b=7/4)
here is your final equation y = 3/-4x + 7/4
