Find the length of the shorter leg of a right triangle if the longer leg is 3 feet more than the shorter leg and the hypotenuse is 3 feet less
than twice the shorter leg.

Answers

The length of the shorter leg of the right triangle is 6 feet.

What is a right triangle?A right triangle is one that has an interior angle of 90 degrees. The hypotenuse, which is also the side of the right triangle that faces the right angle, is its longest side. The height and base make up the two arms of the right angle. A right triangle's hypotenuse is its longest side, its "opposite" side is the one that faces a specific angle, and its "adjacent" side is the one that faces the angle in question.

So, the formula of the hypotenuse: c = √a²+b²

Let, the shorter leg be 'x' and the larger leg be 'x+3' and the hypotenuse be  '2x-3'.

Now, put these values in the formula as follows:

c = √a²+b²2x-3 = √(x+3)²+x²2x-3 = √x² + 3² + x²2x-3 = 2x+3= 6

So, the length of the shorter leg of the right triangle is 6 feet.

The correct option 8 x 10^6 km and 4 x 10⁹ km defines the diameter relation of 500 times to other for the black hole.

What is termed as the diameter?A circle's diameter would be any straight line segment which passes through center of a circle and has endpoints on the circle's circumference. The diameter also is known as the circle's longest chord.It is twice the length of the circle's radius. In other words, a circle's diameter is the line that runs through its center and divides it into two equal portions.

For the given question;

There are black holes with very small diameters.

And also there are black holes with  millions or billions of kilometres of diameter.

Now, the diameter of one black hole is 500 times the other.

Consider the first option;

Let the diameter of 1st black hole be 8 x 10^6 km.

Then, the diameter of 2nd black hole be 500 times of the  8 x 10^6 km.

= 500 ×  8 x 10^6 km

= 4 x 10⁹ km

Determine the domain and range of (g ○ f)(x) if f of x is equal to 4 over the quantity x squared minus 4 end quantity and g(x) = x + 2.

Answers

For the function (gof)(x) the Domain is {x∈ R| ,x ≠ –2, 2} , the Range is {(–∞, 1)∪(2, ∞)} .

In the question ,

it is given that

the function f(x) is given as "4 over the quantity x squared minus 4" ,

which means

f(x)=4/(x²-4)

and g(x)=x+2

we know ,

(gof)(x) = g(f(x))= f(x) + 2

= 4/(x²-4) + 2

taking LCM as (x²-4) and solving further ,

we get

= [tex]\frac{4+2x^{2} -8}{x^{2} -4}[/tex]

= (2x²-4)/(x²-4)

the fraction is defined only when the denominator is non zero,

So for Domain

x²-4 ≠ 0

x² ≠ 4

x ≠ +2,-2

So, the domain is all real numbers except the numbers 2,-2 .

For Range , the graph of the function (gof)(x) is plotted below ,

From the graph we can see that the function does not have any value from y=1 to 2 .

So, the Range will be R={(∞, 1)∪(2, ∞)}.

I need to find the volume and surface area of this 3d composite figure

Answers

Volume:

To find the volume we notice that this figure is made of a cube minus a cone.

The volume of a cube is given as:

[tex]V=l^3[/tex]

Here the length of each side is 6 cm.

The volume of a cone is given as:

[tex]V=\frac{1}{3}h\pi r^2[/tex]

here the radius of the cone is 2 cm (half the diameter shown) and its height is 6 cm.

Hence the volume of the composite figure is:

[tex]V=(6)^3-\frac{1}{3}(6)\pi(2)^2=190.87[/tex]

Surface area:

The surface area of the figure is the surface area of the cube minus the surface area of the cone.

The surface area of the cube is given by:

[tex]SA=6l^2[/tex]

in this case the lenght of each side is 6 cm.

The surface area of the cone is given by:

[tex]SA=\pi r^2+\pi rl[/tex]

where r is the radius of the cone and l is the slant height. The radius of the cone is 2 cm. To find the slant height we need to remember that this slant height is the hypotenuse of a right triangle with one leg equal to the radius and the other leg equal to the height of the cone. Then, using the pythagorean theorem we have:

[tex]\begin{gathered} l^2=2^2+6^2 \\ l^2=4+36 \\ l=\sqrt[]{40} \end{gathered}[/tex]

Once we have all the values we need we have that the surface area is:

[tex]SA=6(6)^2-\pi(2)^2-\pi(2)(\sqrt[]{40)}=163.70[/tex]

Summing up we have that:

• The volume is 190.87 cubic cm.

,

• The surface area is 163.70 squared cm.

What is the equation of the line that passes through the point (4,-7) and has a slope of -3

Answers

Answer: y=-3x+5

Step-by-step explanation:

1) List in a y = mx + b

y = -3x+b

2) Next fill in x and y with the points given

-7 = -3(4) + b

3) Solve

-7 = -3(4) + b

-7 = -12 + b

5 = b

4) Apply b to the y =mx + b

y=-3x+5

Answer: y= -3x +5

Step-by-step explanation:

Slope: y= mx+ b

m being the slope

b being the y intercept

You're given the slope, so you substitute m for -3

y=mx+b

y =  -3x + b

You have the coordinates (4, -7) which you can substitute (the line passes through that point.)

-7 = -3(4) + b

-7 = -12 + b

+12   +12

5= b

y= -3x + b

Check:

-7 = -3(4) + 5

-7 = -12 + 5

-7 = -7

Which of the following are possible equations of a parabola that has no real solutions and opens downward?y > = -(x + 4)2 - 2y > = -(x + 4)2 + 2y > = -x2 - 2y > = (x - 4)2 + 2y > = -(x - 4)2 - 2

Answers

We have to identify the parabola that:

a) has no real solutions (it has complex roots).

b) opens downward.

The equations are in vertex form, so to have no real solutions and be downward, the vertex should have a value of y that is less than 0:

If the vertex had a value of y greater than 0, if it opens downward, there should be two values of x so that f(x) = 0. Then, this would be the real solutions.

The vertex form can be written as:

[tex]y=a(x-h)^2+k[/tex]

where (h,k) are the coordinates of the vertex.

Then, we need k <= 0.

The equations that satisfy this are:

y = -(x + 4)² - 2

y = -x² - 2

y = -(x - 4)² - 2

The second condition is that the parabola opens downward. This means a quadratic coefficient "a" with negative value.

All this three equations satisfy this condition.

We can graph them and check if the conditions are satisfied:

Answer:

There are 3 equations that satisfy the two conditions:

y = -(x + 4)² - 2

y = -x² - 2

y = -(x - 4)² - 2

Solve the following simultaneous equation using elimination or substitution method

Answers

Answer:

(15, 10) and (10, 15)

Explanation:

The given system of equation is

x + y = 25

xy = 150

To solve the equation, we will use the subtitution method, so first, we need to solve the first equation for y

x + y = 25

x + y - x = 25 - x

x y= 25 - yx

Then, substitute y = 25 - x on the second equation, we get

xy = 150

x(25 - x) = 150

x(25) - x(x) = 150

25x - x² = 150

Now, we can rewrite the equation as

25x = 15 + x²

0 = 150 + x² - 25x

0 = x² - 25x + 150

Therefore, we need to find the values of x that satisfies

x² - 25x + 150 = 0

Now, we need to factorize this equation, so two numbers that multiply to 150 and add to -25 are -15 and -10. Then

(x - 15)(x - 10) = 0

So, the solutions are

x - 15 = 0

x = 15

or

x 10 = 0

x = 10

Then, the values of y are

If x = 15

y = 25 - x

y = 25 - 15

y = 10

If x = 10

y = 25 - x

y = 25 - 10

y = 15

Therefore, the solutions are (15, 10) and (10, 15)

To estimate the height of a building, Ami walks 200 meters from its base and plants a 2m tall stick. Ami lines up the top of the building and the top of the stick. At this point, Ami is 5 meters from the stick. Estimate the height of the building if Ami's eye level is the ground. ​Show all work.

Answers

Using T- ratios, We concluded that the height of the building is 82m.

According to the given question,

the distance between stick and building is 200m,

height of the stick is 2m,

Ami is standing at 5m from the stick,

Let the height of the building = x

So, By observing the pictorial representation of the question through image attached,

And using T - ratios along with

we can conclude that

Tan A = Height of the building / distance between Ami and building

⇒ Tan A = x / 5 + 200                              ......... (1)

Tan A = Height of the stick / Distance between Ami and stick

⇒ Tan A = 2 / 5                                         ............(2)

On equating (1) and (2)

x / 5 + 200  = 2 / 5        

x / 205 = 2/5

x = 2/5 × 205

x = 82

∴ Height of the building is 82m
