The length of the base of an isosceles triangle is x. The length of a leg is 2x-6. The perimeter of the triangle is 38. Find X

Answers

Answer:

x = 10

Step-by-step explanation:

Perimeter of a triangle = the sum of the three sides.

In an isosceles the legs are equal (2x - 6) and the base is x

Perimeter = (x) + (2x - 6) + (2x - 6)

38 = 5x - 12

38 + 12 = 5x

50 = 5x

[tex]\frac{50}{5} = \frac{5x}{5}[/tex]

10 = x

A rocket is launched from a tower. The height of the rocket, y in feet, is related to the time after launch, x in seconds, by the given equation. Using this equation, find the maximum height reached by the rocket, to the nearest tenth of a foot.
y=−16x^2+146x+137

Answers

Answer:

470.1

Step-by-step explanation:

Since this is a parabola that opens down, the maximum height is where the graph has a horizontal tangent line.

This is where the derivative=0

Since it is a parabola that opens down, we do not need to test the sides of the point where the derivative=0 as the vertex is a local maximum and the only point with a horizontal tangent.

y=[tex]-16x^2+146x+137[/tex]

y'=[tex]-32x+146[/tex]=0

-32x+146=0

x=[tex]\frac{146}{32}[/tex]=[tex]\frac{73}{16}[/tex] This is the x-coordinate of the vertex

Now plug this back into the original equation to find the maximum height.

f(73/16)=[tex]-16(\frac{73}{16})^2+146(\frac{73}{16} )[/tex]+137

=[tex]\frac{-73^2}{16} +666.125+137[/tex]

=-333.0625+666.125+137

=470.0625

To the nearest tenth this is 470.1

Airline fares are $200 for first class and $150 for business class. If a flight had
52 passengers who paid a total of $8500. How many first class passengers.
we’re on the trip?

Answers

Answer:

14 first class passengers

Step-by-step explanation:

Set a system of equations as below:

x + y = 52200x + 150y = 8500

Multiply the first equation by 150 and subtract from the second equation.

This will eliminate y, solve for x:

200x + 150y - 150x - 150y = 8500 - 150*5250x = 700x = 700/50x = 14

the deer population in georgia was 450,000 in 2010, and the population doubles every 5 years. in what year will the deer population in georgia reach 1 million

Answers

Answer:

We know that in 2020 the population of deer will be 900,000 based on the given numbers. In another 5 years the population will be over 1 million (1,350,000) in order to calculate when it will reach 1 million we need to see how much growth is gained per year. I believe to obtain that information we will need to divide 450,000 by 5 that equals 90,000 a year. So if I’m 2020 the population of deer will be 900,000 than add 90,000 until you reach your 1 million marker. In this case 2021 would be 990,000 thousand so 2022 would be 1,080,000. So your answer should be year 2022. Hope that helps

Find the perimeter of an isosceles triangle. The base is 3y and each side is (0.6y-7).

Answers

Answer:

Perimeter = 4.2y - 14

Step-by-step explanation:

Perimeter of a triangle = the sum of the three sided of the triangle.

In an isosceles triangle, there are two equal sides and a base.

Perimeter = (0.6y - 7) + (0.6y - 7) + 3y

Perimeter = (0.6y + 0.6y + 3y) - 7 - 7

Perimeter = 1.2y + 3y - 14

Perimeter = 4.2y - 14

Here is a scale drawing of a garden.
Tom wants to plant a tree in the garden according to the following rules:
it must be 4 m from A and 2 m from CD.
Place a cross where Tom can plant the tree.

Answers

The location of the tree can be found by taking point A as the origin of

coordinate plane, represented by the drawing area.

Response:

The the graph showing the location where Tom can plant the tree is attached.

Method used to find the location for planting the tree

The area Tom wants to plant the tree in the garden is given by the following rule;

Distance of the tree from A = 4 m

Distance of the tree from CD = 2 m

1 cm in the scale drawing = 2 m

Solution:

Taking point A as the origin, we have;

The location of the tree from point A is given by the radial length, r = 2 cm.

The distance of the tree from the line CD is given by the line, y = 1.5 cm,

given that 1 cm from CD = 1.5 cm from point A

Therefore, we have;

The y-coordinate of the location of the tree is; y = 1.5

Equation of the circular distance from A is; x² + y² = r²

Where;

r = 2

y = 1.5

We have;

x² + 1.5² = 2²

x² = 2² - 1.5² = 1.75

x = √(1.75)

The coordinate of the location of the tree from A is; (√(1.75), 1.5)

Please find attached, the graph showing the location where Tom can plant the tree in relation to point A.
