Travis spies an owl in a tall tree. He estimates the height of the tree to be 85 feet and the angle of elevation to the bird from where he stands to be 68°. The leaves on the tree make it difficult for Travis to watch the bird, so he takes several steps away from the tree to get a better view. He now estimates his angle of elevation to be 41°.
How many feet did Travis step back to gain a better view of the bird? Round your answer to the nearest hundredth of a foot.

The area of the L shaped figure is 258 ft²

Area is the amount of space occupied by a two dimensional figure.

The area of a rectangle is given by:

Area = length * breadth

From the diagram, the area is:

Area = [18 * (21 - 12)] + (12 * 8) = 258 ft²

The area of the L shaped figure is 258 ft²

Medians bisect eachother at centroid in ratio 2:1

SU is perpendicular bisector

UY=UZ

So

Apply Pythagorean theorem

[tex]\\ \tt\hookrightarrow VY^2=XS^2-VS^2=80^2-48^2=6400-2304=4096\implies VY=64[/tex]

Answer:

XS = 80

YZ= 132

VY = 64

Step-by-step explanation:

Firstly, SU is a perpendicular bisector

so, UV= UZ and YZ = 2(66) = 132

Each median bisect each other at centre with the ratio 2 : 1

therefore ZS = 80 = XS

now , by using P.G.T

VY² = XS²-VS²

=> 80²-48²

=> 6400-2304

=> 4096

=> √4096

=> 64

VY = 64

Answer:

6.75

Step-by-step explanation:

first let's simplify whatever is inside the parantheses

8(2x-10)=28

8*2(x-5)=28

16(x-5)=28

now we divide both sides by 16 to get rid 16

x-5 = 28/16

now move -5 to the right side

x = 28/16 + 5

x = 28/16 + 80/16 = 108/16 = 6.75

Answer:

x² + x - 12 = 0

Step-by-step explanation:

If x = -4 and x = 3 are solutions to a quadratic equation, then

(x + 4)(x - 3) = 0

Expand the brackets:  x² - 3x + 4x - 12 = 0

Combine like terms:  x² + x - 12 = 0

Answer:

[tex]y = 4[/tex]

Step-by-step explanation:

First, find the derivative of f:

[tex]\displaystyle \begin{aligned} f'(x) & = \frac{d}{dx}\left[ 2x^3 - 3x^2 + 5\right] \\ \\ & = 6x^2 - 6x \\ \\ & = 6x(x-1)\end{aligned}[/tex]

Find the instantaneous slope at x = 1:

[tex]\displaystyle \begin{aligned} f'(1) & = 6(1)((1)-1) \\ \\ &= 0 \end{aligned}[/tex]

From the point-slope form, find the equation of the line:
[tex]\displaystyle \begin{aligned}y - y_1 & = m(x-x_1) \\ \\ y - (4) & =(0)(x-(1)) \\ \\ y & = 4 \end{aligned}[/tex]

In conclusion, the equation of the tangent line is y = 4.

Tammy must give Qiulian 800 cards, so that they have the same number of card.

Given the following data:

Translating the word problem into an algebraic expression, we have;

Qiulian and Tammy have 2400 cards:

[tex]Q+T=2400[/tex]    .....equation 1.

Tammy has twice as many cards as Qiulian:

[tex]T=2Q[/tex]   .....equation 2.

To determine the amount of card that Tammy must give Qiulian so that they have the same number of card:

Substituting eqn. 2 into eqn. 1, we have:

[tex]Q+2Q=2400\\\\3Q=2400\\\\Q=\frac{2400}{3}[/tex]

Q = 800 cards.

For Tammy:

[tex]T =2Q\\\\T=2\times 800[/tex]

T = 1600 cards.

Therefore, Tammy must give Qiulian 800 cards, so that they have the same number of card.

Answer:

It can be any measure

Step-by-step explanati

Answer and Step-by-step explanation:

So for this question, we need to create an equation. We will use one of the most common forms of equations of math, which would be the linear equation of y=mx+b. The only difference is, we need to change the = to a ≥ symbol, meaning greater than or equal to, because the 100 dollars needs to be more or equal to the amount spent. But we cannot solve this problem until we know where everything goes.

So, the 100 is all she can spend, so this is where the ≤ comes in handy. She can use less than or equal to the amount of 100 dollars for the food for this party. And because she started out with 19 dollars, that can be added into the problem. So far we have:

100 ≥ __x + 19.

Now we need to find what the missing part of the equation is. But first let's change the x to p in this equation so that it is easier to understand. The p stands for the amount of pizzas purchased. Each pizza costs 7 dollars, so the equation should look like this:

100 ≥ 7p + 19. Now we solve for p.

-19           - 19 Subtract 19 from both sides to cancel out the positive 19 (+ 19).

81 ≥ 7p           Divide 7 into 81 to single out p.

7      7            So p = 81/7. But we can't have 81/7 of a pizza, so we convert this to a decimal then round. So: 11.57142857… is the decimal form.

Now we need to round, because that is way too big. So, we round to the nearest whole number. So we look at the placement behind it (The tenths placement in this situation). Because the placement behind it (5) is on the 5 - 9 scale, the placement before it gets rounded up.

So, Ava can buy 12 pizzas.

[tex]x=-2, y=-4[/tex]

Answer:

[tex]{x,y} = {-2,-4}[/tex]

Step-by-step explanation:

[tex]2x + 5y = -24 \\ 2x + y = -8[/tex] <---------- Linear equations given

Graphic Representation of the Equations : PICTURE

[tex]5y + 2x = -24 \\ y + 2x = -8[/tex]

Solve by Substitution :

// Solve equation [2] for the variable  y

[tex][2] y = -2x - 8[/tex]

// Plug this in for variable  y  in equation [1]

[tex][1] 2x + 5*(-2x-8) = -24\\ [1] -8x = 16[/tex]

/ Solve equation [1] for the variable  x

[tex][1] 8x = - 16 [1] x = - 2[/tex]

// By now we know this much :

[tex]x = -2 \\ y = -2x-8[/tex]

1. Ratio of medals won by Josephine to the total number won by the team: 1/13 (A)

2. Ratio of medals won by Jacob to medals won by Antonio: 2/1 (D)

Ratio can be described as a quantitative relation that compares how many times a value is contained in another.

1. Ratio of medals won by Josephine to the total number won by the team:

Total won by the team = 26

Medals won by Josephine = 2

Ratio = 2:26 = 2/26

= 1/13 (A)
