During a windstorm, part of the top of a flagpole breaks off. The broken top portion touches the ground at an angle of 65degrees

14feet from its base.
How tall was the pole before the windstorm? Round your answer to one decimal place. Can someone answer this please

The situation in the problem creates a right triangle with a base of 14ft. An angle of 65 degrees means that the triangles has...

A hypotenuse of $hyp = \frac{14ft}{cos(45)} = 33.13ft$ , representing the length of the broken part of the pole.

An opposite of $sin(65)*hyp = sin(65)*33.1ft = 30.0ft$ , representing the height of the part of the flag that still stands.

The total original flag height is the sum of the two parts.
$h = 30.0ft + 33.13ft = 63.13ft$

A student researcher conducts an experiment that investigates the effects of a new mathematics website on student achievement. S

pickupchik [31]

Answer:

A, B and C

Step-by-step explanation:

A. Adding another researcher to provide ratings will make the study less biased.

B. A quiz or exam will show which students have a better understanding of the math material. Better quiz or exam results show that the site is more effective for a student with or without the supplemental instruction.

C. Having a greater sample size is better because a greater scope of students is covered. Different students have different abilities and learning preferences.

If f(1) = 10 and f(n) = f(n = 1) – 4 then find the value of f(5).

svetoff [14.1K]

Given:

$f(1)=10$ and $f(n)=f(n-1)-4$ .

To find:

The value of f(5).

Solution:

We have,

$f(n)=f(n-1)-4$

For $n=2$ ,

$f(2)=f(2-1)-4$

$f(2)=f(1)-4$

$f(2)=10-4$

$f(2)=6$

For $n=3$ ,

$f(3)=f(3-1)-4$

$f(3)=f(2)-4$

$f(3)=6-4$

$f(3)=2$

For $n=4$ ,

$f(4)=f(4-1)-4$

$f(4)=f(3)-4$

$f(4)=2-4$

$f(4)=-2$

For $n=5$ ,

$f(5)=f(5-1)-4$

$f(5)=f(4)-4$

$f(5)=-2-4$

$f(5)=-6$

Therefore, the value of $f(5)$ is $-6$ .

choose the point-slope form and f the equation below that represents the line through the point (6,-3) and has a slope of 1/2

AveGali [126]

Answer:

The point-slope form of this equation would be y + 3 = 1/2(x - 6)

Step-by-step explanation:

In order to find this, start with the base form of point-slope form.

y - y1 = m(x - x1)

Now input the slope for m and the point for (x1, y1)

y - -3 = 1/2(x - 6)

y + 3 = 1/2(x - 6)

Which group of three squares will form a right triangle when<br> joined at their vertices?

Ilia_Sergeevich [38]

Answer:

Option ?) 17 cm, 15 cm, 8 cm

<em>The assignment should have </em><em>four options</em><em> to choose from, but there is only a picture of two. </em>

Step-by-step explanation:

<em>None of the squares </em><em>shown</em><em> form a right triangle. To determine if sides form a right triangle, you use </em><em>this</em><em> formula:</em>

a²+b²=c²

<em>We are given two options in the picture.</em>

Option A) 18, 10, and 8.

Option B) 12, 9, and 6.

<em>So, now we need to apply the formula:</em>

Option A)

║8² + 10² = 18²

↓

║64 + 100 = 324

↓

║FALSE

Option B)

║6² + 9² = 12²

↓

║36 + 81 = 144

↓

║FALSE

<em>Both of these options are false.</em><em> But, I decided to look up this assignment to check my answer. It turns out, there are </em><em>4 options</em><em>, and you only had a picture of two. So, what's the answer?</em>

<em />

<em>There is an answer choice that shows 3 squares with the lengths of 17 cm, 15 cm, and 8 cm. </em><em>This is the correct answer</em><em>.</em>

<em />

<em>For proof, let's apply the formula:</em>

Option ?)

║8² + 15² = 17²

↓

║64 + 225 = 289

↓

║TRUE

<em>[Since the option isn't shown, I'll put a '?' so there is no confusion]</em>
