a vertical pedestal stands on the ground and is surmounted by a vertical flag staff of height 5 m.At a point on the ground the a

Scilla [17]

Answer:

2.5 ft

Step-by-step explanation:

The figure for the given scenario is shown below.

There are two right angled triangles, ΔACD and ΔBCD

The height of flag staff is represented by segment AB, BC is the height of pedestal stand , D is a point on the ground that makes angles 30° and 60° with the bottom and top of staff at B and A respectively.

AB = 5 ft. Let the height of pedestal stand be $x$ ft and the distance of point D from the bottom of stand be $y$ ft as shown in the figure.

Now, from ΔACD,

$tan(60)=\frac{AC}{CD}\\ \sqrt{3}=\frac{5+x}{y}\\ \sqrt{3}y=5+x$

From ΔBCD,

$tan(30)=\frac{BC}{CD}\\\frac{1}{\sqrt{3}}=\frac{x}{y}\\y=\sqrt{3}x$

Plug in the value of $y$ in the first equation and solve for $x$ .

$\sqrt{3}y=5+x\\\sqrt{3}(\sqrt{3}x)=5+x\\3x=5+x\\2x=5\\x=\frac{5}{2}=2.5 \textrm{ ft}$ .

Therefore, the height of the pedestal stand is 2.5 ft.

Mario is constructing a frame for 10 in. by 8 in. photo. He wants the frame to be the same with all the way around in the same a

Yuri [45]

Answer: 12 in. by 10 in.

Step-by-step explanation:

Given: The dimensions of photo is 10 in. by 8 in.

Therefore, Area of photo= $10\times8=80\ in.^2$

Area of frame with photo=120 square inches

Let x be the width of the frame, then we have

Length of frame with photo= 10+2x inches

Width of frame with photo =8+2x inches

Now, $(10+2x)(8+2x)=120$

$80+16x+20x+4x^2=120\\\Rightarrow\ 4x^2+36x-40=0\\\Rightarrowx^2+9x-10=0\\\(x-1)(x+10)=0\\\Rightarrow\ x=1,...........[text{Since length can not be negative so it cannot be -10}]$

Thus, dimension of frame = $(10+2(1))(8+2(1))=12\ in.\ by\ 10\ in.$

2. Tell whether the segment lengths form an acute, right, or obtuse? 9, 12, 17

blondinia [14]

Answer:

obtuse angled triangle

Step-by-step explanation:

Given 3 segments , say a, b and c , with c the longest then

• If a² + b² = c² ⇒ right triangle

• If a² + b² > c² ⇒ acute triangle

• If a² + b² < c² ⇒ obtuse triangle

Here c = 17 and 17² = 289

9² + 12² = 81 + 144 = 225

Since 225 < 289 , then triangle is obtuse

The new balance is 1.05 times the previous balance. An exponential function can provide a suitable shortcut.

Step-by-step explanation:

The worksheet you show tells you exactly how to do the calculations and where to put the numbers. For such repetitive calculations a spreadsheet is a very useful tool.

Each new balance is the previous balance multiplied by 1.05. Repetitive multiplication is signified using an exponent. For multiplication by 1.05 six times, the multiplying factor can be 1.05^6.
