Two buildings on opposite sides of a street are 40 meters apart. From the top of the shorter building, which is 176 meters high, the angle of elevation to the top of the taller building is 13 degrees. Find the height of the taller building to the nearest meter. *

Answers

Answer 1

Answer:

185 m

Step-by-step explanation:

From the solution diagram shown :

The height of the taller building is :

(Height of shorter building + h)

Height of shorter building is given as 176 m

The height, h can be obtained using Pythagoras :

Tan θ = opposite / Adjacent

Tan 13 = h / 40

h = tan 13 * 40

h = 9.235 m

Hence, height of taller building :

176 m + 9.235 m

= 185.235 m

= 185 m

Answer:

sin D = 0.25

Step-by-step explanation:

If ∠E = 90°, it means that the triangle is a right angle triangle.

Thus, hypotenuse will be the longest side which will be DC = 65

Since we are given CE = 16 and ED = 63, I have attached a diagram showing this triangle.

From the diagram, since we are looking for sin ∠D, we can say that;

sin D = opposite/hypotenuse

Now, opposite = CE = 16

Hypotenuse = CD = 65

Thus;

sin D = 16/65

sin D = 0.2462

Approximating to the nearest hundredth gives;

sin D = 0.25


What are the slope and the y-intercept of the linear function that is represented by the equation 8x-2y = 5?

Answers

Answer:

The slope is 4 and the y intercept is -5/2

Step-by-step explanation:

8x-2y = 5

Solve for y to get the equation in slope intercept form

Subtract 8x from each side

8x-8x-2y =-8x+ 5

-2y = -8x+5

Divide by -2

-2y/-2 = -8x/-2 + 5/-2

y = 4x -5/2

This is in slope intercept form y= mx+b where m is the slope and b is the y intercept

The slope is 4 and the y intercept is -5/2

Victor draws one side of equilateral ∆PQR on the coordinate plane at points P (–9, –2) and Q (–2, –2). What are the two possible coordinates of vertex R? Round to the nearest tenth.

Answers

Answer: [tex](-5.5,4.062)\ \text{and}\ (-5.5,-8.062)[/tex]

Step-by-step explanation:

Given

The two vertices of a equilateral triangle are [tex](-9,-2)\ \text{and}\ (-2,-2)[/tex]

Suppose the third vertex is [tex](x,y)[/tex]

Side length in equilateral triangle are equal.

[tex]\Rightarrow \sqrt{\left( -2+9\right)^2+\left( -2+2\right)^2}=\sqrt{\left( x+9\right)^2+\left( y+2\right)^2}\\\text{squaring both sides}\\\\\Rightarrow 7^2=\left( x+9\right)^2+\left( y+2\right)^2\quad \ldots(i)\\\\[/tex]

Similarly,

[tex]\Rightarrow \sqrt{\left( -2+9\right)^2+\left( -2+2\right)^2}=\sqrt{\left( x+2\right)^2+\left( y+2\right)^2}\\\\\Rightarrow 7^2=\left( x+2\right)^2+\left( y+2\right)^2\quad \ldots(ii)[/tex]

Subtract (i) and (ii)

[tex]\Rightarrow \left( x+9\right)^2-\left(x+2\right)^2=7^2-7^2\\\\\Rightarrow (x+9+x+2)(x+9-x-2)=0\\\Rightarrow (2x+11)7=0\\\\\Rightarrow x=-\dfrac{11}{2}[/tex]

Insert the value of [tex]x[/tex] in equation (ii)

[tex]\Rightarrow \left(-5.5+2\right)^2+\left(y+2\right)^2=7^2\\\\\Rightarrow \left(-5.5+2\right)^2+\left(y+2\right)^2-\left(-5.5+2\right)^2=7^2-\left(-5.5+2\right)^2\\\\\Rightarrow \left(y+2\right)^2=36.75\\\\\Rightarrow y=4.06217\dots ,\:y=-8.06217[/tex]

So, two possible vertex are [tex](-5.5,4.062)\ \text{and}\ (-5.5,-8.062)[/tex]

The function f(x) = –x2 – 4x + 5 is shown on the graph. On a coordinate plane, a parabola opens down. It goes through (negative 5, 0), has a vertex at (negative 2, 9), and goes through (1, 0). Which statement about the function is true? The domain of the function is all real numbers less than or equal to −2. The domain of the function is all real numbers less than or equal to 9. The range of the function is all real numbers less than or equal to −2. The range of the function is all real numbers less than or equal to 9.

Answers

Answer:

(-infinity, 9]

Step-by-step explanation:

The range of the function is 'all real numbers less than or equal to 9.'  We are told that the vertex is at (-2, 9) and that the curve opens downward, which indicates that 9 is the maximum function value, and that the function can take on any value less than or equal to 9.

The domain is 'the set of all real numbers,' which is true for any polynomial.

using cos rule

cos A = adjacent/hypotenuse

cos A =10/15

cos A =0.66

[tex]A=cos^{-1} (0.6666)[/tex]

A=48.194

A=48.2

angle A + angle B + angle C =180 degree (being sum of interior angles of a triangle)

48.2 + angle B + 90 =180

138.2 + angle B =180

angle B =180-138.7

angle B =41.8

for BC

using pythagoras theorem

a^2 + b^2 = c^2

AC^2 + BC^2 = AB^2

10^2 + BC^2 = 15^2

BC^2 = 225-100

BC^2 = 125

Henry and Liani have 200 feet of wood to frame a flower bed. Henry wants the bed to be a square, while Liani wants it to be a rectangle with dimensions of 55 feet and 45 feet. Which statement is true regarding the areas of the two flower beds? Henry's design would result in a larger flower bed because its area would be 2,500 square feet. Liani's design would result in a larger flower bed because its area would be 2,500 square feet. Henry's and Liani's designs would result in flower beds with the same area. Henry's and Liani's designs are not possible with the given amount of wood.

Answers

Answer:

A. Henry's design would result in a larger flower bed because its area would be 2,500 square feet.

Step-by-step explanation:

A. Henry's design would result in a larger flower bed because its area would be 2,500 square feet.

B. Liani's design would result in a larger flower bed because its area would be 2,500 square feet.

C. Henry's and Liani's designs would result in flower beds with the same area.

D. Henry's and Liani's designs are not possible with the given amount of wood.

Length of wood = 200 feet

Henry's square bed design = 200 feet / 4

= 50 feet

Note: A square has 4 equal sides, hence, the division by 4

Each side of the square bed = 50 feet

Area of the square bed = length ²

= (50 feet)²

= 2,500 square feet

Liani rectangular bed design

Length = 55 feet

Width = 45 feet

Note: adding of 2 length and 2 width = 200 feet

That is,

2(55) + 2(45)

= 110 + 90

= 200 feet of wood

Area of Liani rectangular bed design = length × width

= 55 feet × 45 feet

= 2,475 square feet

A. Henry's design would result in a larger flower bed because its area would be 2,500 square feet.

A. Henry's design would result in a larger flower bed because its area would be 2,500 square feet.

Answer: [tex]a_{n}=4n+-3[/tex]

Step-by-step explanation:

The way arithmetic sequences are usually written is:

[tex]a_{n} =a_{1} +(n-1)d[/tex]

[tex]a_{n}[/tex] is the the term you are looking for. It has an n because we aren't looking for a specific one.

[tex]a_{1}[/tex] is the first term of the sequence. In this case that is 1.

n is the term position. Meaning if you wanted to find the fifth term you'd sub 5 in for n.

d is the common difference. In this case it is 4.

Now we can sub these values in.

[tex]a_{n} =1 +(n-1)4[/tex]

We can simplify the right part of the equation.

[tex]a_{n} =1 +(n-1)4\\a_{n} =1 +(4)(n)-(4)(1)\\a_{n}=1+4n-4\\a_{n}=4n+1-4\\a_{n}=4n+-3[/tex]
