Answer:
Step-by-step explanation:
If you meant f(x) = √x - 1, then the domain is [0, infinity).
If you meant f(x) = √(x-1), then the domain is [1, infinity).
When any ambiguity may rear its ugly head, use parentheses, as indicated here.
Answer:
6/4
Step-by-step explanation:
Answer:
22.77°
Step-by-step explanation:
Using SOH CAH TOA trigonometry identity
Height of the building (opposite side) = 172ft
Length of the shadow (hypotenuse) = 444ft
Using SOH
sin theta = opp/hyp
Sin theta = 172/444
Sin theta = 0.387
theta = arcsin0.387
theta = 22.77°
Hence the angle of depression is 22.77°
If youre trying to solve for the variables you have to solve for one of them in one equation first, so if you solved for x in 2x+3y=16 youd get x=8-(3/2)y. Then youd have to sub in that x for the x in the other equation so youd get 3(8-(3/2)y)-2y=13 then solve for y. Once you have the value of y it should be the same in both equations. Plug that new value of y into the equation of youre choosing then sove for x
The expression that has a value of 62.45 is the second answer choice 0.6245 × 10²
To determine the expression that has a value of 62.45 among the given answer choices, we will evaluate each of the answer choices.
- For the first answer choice - 0.006245 × 105 = 0.006245 × 10⁵
0.006245 × 10⁵ = 624.5
- For the second answer choice - 0.6245 × 102 = 0.6245 × 10²
0.6245 × 10² = 62.45
- For the third answer choice - 6.245 ÷ 101 = 6.245 ÷ 10¹
6.245 ÷ 10¹ = 0.6245
- For the fourth answer choice - 624.5 × 103 = 624.5 × 10³
624.5 × 10³ = 624500
From above, the second answer choice is the expression that has a value of 62.45
Hence, the expression that has a value of 62.45 is 0.6245 × 10²
