Answer:

The absolute value of 4+7i is equal to \sqrt{4^{2}+7^{2}}.

The absolute value of the 4+7i be \sqrt{65}.

Step-by-step explanation:

The absolute value is given by .

|a + bi| = \sqrt{a^{2}+b^{2}}

Now find the absolute value of the 4+7i.

|4+ 7i|= \sqrt{4^{2}+7^{2}}

|4+ 7i| = \sqrt{16+49}      

|4+ 7i| = \sqrt{65}  

Therefore the absolute value of the 4+7i is \sqrt{65} .

mario62 [17]

Answer:

<u>This assume the equation is 35y = mx + c, and that r is meant to be x.</u>

Step-by-step explanation:

35y = mx + c

35y = -2(-7) - 3

35y = 14 - 3

35y = 11

y = (11/35)

The diagram below shows a student using a clinometer to measure the height of a flagpole. When the student stands 40 feet away f
AVprozaik [17]
The correct answer is the flagpole is <span>33 feet high</span>.

Explanation:
Please refer to the attached picture.

We know:
CD = 40 feet
AC = 5 feet
∠BDC = α = 35°

Using trigonometry, we know that the definition of the tangent of an angle is the ratio between the opposite side and the adjacent side, therefore:
tan α = BC / CD

Solving for BC:
BC = CD · <span>tan α
      = 40 </span>· tan (35)
      = 28 feet

In order to find the height of the flagpole, we need to add the distance of the clinometer from the ground:
AB = BC + AC
      = 28 + 5
      = 33

Hence, the flagpole is 33 feet high.
