The attached picture has the small triangle, with the tree as one leg of the triangle and the large triangle, with the building as the corresponding leg of that triangle.

In the original picture, the single small line marked in the side are same length (we can call this x) and the double small line marked in the side are of same length (we can call this y).

So as seen in the attached image:

Small triangle's hypotenuse (side opposite of 90 degree angle) is x and the base is y.
Similarly for the larger triangle, hypotenuse is 2x and base is 2y.
Angle labeled a is same for both
Also we have 2 right angles as shown

Hence, the triangles are similar and the ratio of their sides are also same.

If we take any side (let's take the hypotenuse) and compute the ratio. We have,

$\frac{hypotenuse of small triangle}{hypotenuse of large triangle}= \frac{x}{2x} =0.5$ . <em><u>This implies that we can multiply 0.5 to any side of larger triangle to get corresponding side of smaller triangle.</u></em>

So, the building height and tree height are corresponding sides. To get height of tree, we multiply 0.5 to 120 to get 60 as the height of the tree.

$120*0.5=60$ ft

This is the correct answer.

ANSWER: 60 ft

Given the force field F, find the work required to move an object on the given oriented curve. F = (y, - x) on the path consisti

timofeeve [1]

Answer:

0

Step-by-step explanation:

We want to compute the curve integral (or line integral)

$\bf \int_{C}F$

where the force field F is defined by

F(x,y) = (y, -x)

and C is the path consisting of the line segment from (1, 5) to (0, 0) followed by the line segment from (0, 0) to (0, 9).

We can write

C = $\bf C_1+C_2$

where

$\bf C_1$ = line segment from (1, 5) to (0, 0)

$\bf C_2$ = line segment from (0, 0) to (0, 9)

so,

$\bf \int_{C}F=\int_{C_1}F+\int_{C_2}F$

Given 2 points P, Q in the plane, we can parameterize the line segment joining P and Q with

<em>r(t) = tQ + (1-t)P for 0 ≤ t ≤ 1 </em>

Hence $\bf C_1$ can be parameterized as

$\bf r_1(t) = (1-t, 5-5t)$ for 0 ≤ t ≤ 1

and $\bf C_2$ can be parameterized as

$\bf r_2(t) = (0, 9t)$ for 0 ≤ t ≤ 1

The derivatives are

$\bf r_1'(t) = (-1, -5)$

$\bf r_2'(t) = (0, 9)$

and

$\bf \int_{C_1}F=\int_{0}^{1}F(r_1(t))\circ r_1'(t)dt=\int_{0}^{1}(5-5t,t-1)\circ (-1,-5)dt=0$

$\bf \int_{C_2}F=\int_{0}^{1}F(r_2(t))\circ r_2'(t)dt=\int_{0}^{1}(9t,0)\circ (0,-9)dt=0$

In consequence,

$\bf \int_{C}F=0$

If (x)=x/2-2 and g(x)=2x2+x-3, find (f+g)(x)

Lady_Fox [76]

(f+g)(x)=f(x)+g(x)=
$\frac{x}{2}-2+2x^2+x-3=2x^2+\frac{2}{2}x+\frac{1}{2}x-2-3=$
$2x^2+\frac{3}{2}x-5$

$(f+g)(x)=2x^2+\frac{3}{2}x-5$

Given that events A and B are independent with P(A)=0.24P(A)=0.24 and P(B|A)=0.85P(B∣A)=0.85, determine the value of P(B)P(B), r

NemiM [27]

Answer:

P(B) = 0.85

Step-by-step explanation:

We use the conditional probability formula to solve this question. It is

$P(B|A) = \frac{P(A \cap B)}{P(A)}$

In which

P(B|A) is the probability of event B happening, given that A happened.

$P(A \cap B)$ is the probability of both A and B happening.

P(A) is the probability of A happening.

In this question:

$P(A) = 0.24, P(B|A) = 0.85$

These events are independent.

This means that $P(A \cap B) = P(A)*P(B)$ . So

$P(B|A) = \frac{P(A \cap B)}{P(A)}$

$P(B|A) = \frac{P(A)*P(B)}{P(A)}$

$P(B|A) = P(B)$

So

$P(B) = 0.85$
