Response:
45.54m
Step-by-step breakdown:
See the provided figure
Scarlett's height is represented as AB = 1.65 meters
She stands 90 meters away from the dam, so BE = AC = 90 m
Scarlett measures the angle of elevation to the dam's summit at 26º, which is ∠DBE = 26°
Height of the Dam = DC = EC+DE
AB = EC = 1.65
In triangle BDE
Height of the Dam = DC = 1.65 + 43.89 = 45.54 m
Therefore, the dam's height is 45.54 m.
Answer:
$6.48
Step-by-step explanation:
Initially calculate the 10% discount on $1.60, which results in $1.44. Then multiply $1.44 by 4.5 to find the total, yielding $6.48.
The solution is C. Let’s start by identifying the equations without inequalities. Since there's a dotted line at y = 1, options A and B can be disregarded. Dotted lines indicate exclusivity, so they do not encompass the = sign. Therefore, the answer must be C.
The answer is B; simply use a calculator and apply the absolute value
Greetings:
<span>(4y-3)²=72
4y-3 = </span>±√72
thus, y= (3+√72) /4 or y= (3 - √72) /4
