A boat is heading towards a lighthouse, whose beacon-light is 136 feet above the
alexandr1967 [171]

The distance between the points A to B is 899.9 feet. After rounding off the  nearest integer we get 900 feet as the final answer.

Given we know that CD is perpendicular to AD.

The distance between CD is 139 feet.

As from points A the boat's crew measure the angle of elevation to the beacon as 6°

therefore, m∠A = 6°

Another time the angle of elevation is measured from point B which is 19°.

therefore, m∠DBC = 19°

tan 19° = CD/BD

BD = CD/tan19°

BD = 136/tan 19°

now for tan 6° = CD/AD (tangent is opposite over adjacent)

AD = CD/tan 6°

AD = 136/tan 6°

AB = AD ₋ BD

AB = 136/tan 6° ₋ 136/tan 19°

AB = 1295.2 ₋ 395.3

AB = 900 feet

hence the distance from point A to B is 900 feet.

Please help fast i have no clue what this is meaning<br> ILL MARK U BRAINLIEST
Klio2033 [76]

Answer:

A function is a relation that is either

  1. one-to-one, meaning each output only has one input
  2. many-to-one meaning some outputs can have more that one input, but all inputs only have one output

So, That pic is cramped, don't even know what functions are being referenced but

from the a, b, c, d relation

  • It is not a function because some inputs have more that one output, which fails our man-to-one rule

From the equations

  • -3x = 15 is not a function, because it only has one input but more than one output breaking rule 1
  • 2y=10 is a function because every input x has only one output y, it is many-to-one
  • 3x-0.25y=3 is a function, it is one to one

From the graph

  • the line is a function, since it is many-to-one

From the points

  • the x coordinate is the input, not points (2,6) and (2,3) have the same input for two outputs, breaking rule 2, that each input should have only one output. So the points are not a function

Hello, I need some assistance with this homework question, please? This is for my precalculus homework. Q5

Answer:

T\text{he domain of H\lparen x\rparen is }\lbrace x\lvert x-3,1\rbrace

Step-by-step explanation:

The domain of a function is all the set of possible x-values that the function can take. Then, for the given function:

H\left(x\right)=\frac{-7x^2}{\left(x-1\right)\left(x+3\right)}

The function is undefined when the denominator is equal to 0, then equalize each factor of the denominator to 0:

\begin{gathered} x-1=0 \\ x=1 \\  \\ x+3=0 \\ x=-3 \\  \\ \text{ Then, the domain of H\lparen x\rparen is }\lbrace x\lvert x\ne-3,1\rbrace \end{gathered}
