If you stand 100 feet away from a flagpole, and the angle of elevation to the top of the pole is 31°, what is the height of the

Reika [66]

The height of the flagpole with an angle of elevation to the top of the pole of 31° is 60.086 feet

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

Trigonometric ratio is used to show the relationship between the sides and angles of a triangle.

Let h represent the height of the flagpole, hence:

tan(31) = h/100

h = 60.086 feet

The height of the flagpole with an angle of elevation to the top of the pole of 31° is 60.086 feet

tom had a platter of chocolate wafers. he ate 5 of them and then gave his brother 3 he then moved on to his baseball team of 8 m

Aloiza [94]

Tom started with total 72 chocolate wafers.

<u><em>Explanation</em></u>

The number of chocolate wafers taken by 8 members of the baseball team are in the sequence : $1, 3,5,7,9,11,13,15$

The above sequence is <u>arithmetic sequence</u> with first term(a₁)= 1 and common difference (d) = 2

<u>Formula for Sum</u> of first $n$ terms in arithmetic sequence is....

$S_{n}= \frac{n}{2}[2a_{1}+(n-1)d]$

So, the Sum of 8 terms in that sequence....

$S_{8}= \frac{8}{2}[2(1)+(8-1)(2)]\\ \\ S_{8}= 4[2+7(2)]\\ \\ S_{8}=4(2+14)\\ \\ S_{8}=4(16)=64$

That means, the total number of chocolate wafers taken by the baseball team members is 64. Tom ate 5 and then gave his brother 3 chocolate wafers at first.

So, the total number of chocolate wafers at starting $=64+5+3=72$

guapka [62]

Answer:

$f(x) = 4x + 3 \,,\,\,\,g(x) = 7x-6\\(f/g)(x)=\frac{4x+3}{7x-6}\,,\,\,\,7x-6\neq0\implies x\neq \frac{6}{7}\\\mbox{Domain:}\,\,\,x\in(-\infty,\frac{6}{7}) \cup (\frac{6}{7},+\infty)$
