Please Help In The Question It Should Be If T=-6 When R =-2 Its An Error

Answers

Answer 1

Answer:

r = - [tex]\frac{12}{7}[/tex]

Step-by-step explanation:

Given that r varies inversely as t , then the equation relating them is

r = [tex]\frac{k}{t}[/tex] ← k is the constant of variation

To find k use the condition t = - 6 when r = - 2, then

- 2 = [tex]\frac{k}{-6}[/tex] ( multiply both sides by - 6 )

12 = k, thus

r = [tex]\frac{12}{t}[/tex] ← equation of variation

when t = - 7, then

r = [tex]\frac{12}{-7}[/tex] = - [tex]\frac{12}{7}[/tex]

Answers

Answer:

A Farmhouse shelters 10 animals. some are pigs and some are ducks. Altogether there are 36 legs. How many of each animal are there? Answer: 8 pigs and 2 ducks.

1. (A) p + d = 10

2. (B) 4p + 2d = 36

3. Multiply equation (A) with -2; -2p minus -2d = -20

4. When subtracted from equation (B), this gives you.. 2p = 16, pigs = 8

5. Use this 8 to the second equation by substitution.. 2d = 4, ducks = 2

In RST, X is the midpoint of RS and Y is the midpoint of RT. Given that XY = 3z + 2 and ST = 7z - 1, what is the value of z?

Answers

Answer:

Step-by-step explanation:

XY=ST/2

3z+2=(7z-1)/2

2*(3z+2)=7z-1

2*3z+2*2=7z-1

6z+4=7z-1

+1         +1

6z+5=7z

-6z      -6z

5=z

The required value of z is 5.

Given that,

In RST, X is the midpoint of RS,

And Y is the midpoint of RT.

XY = 3z + 2 and ST = 7z - 1.

We have to determine,

What is the value of z.

According to the question,

X is the midpoint of RS,

And Y is the midpoint of RT.

Therefore,

[tex]XY = \frac{ST}{2}[/tex]

Putting the value of XY and ST in the equation,

XY = 3z + 2 and ST = 7z - 1.

Then,

[tex]XY = \frac{RS}{2} \\\\3z+ 2 = \frac{7z-1}{2}\\\\2 \times(3z+2) = 7z-1\\\\= 6z+4= 7z-1\\\\6z-7z = -1-4\\\\-z = -5\\\\= z = 5[/tex]

Hence, The required value of z is 5.

Answers

Answer:

Step-by-step explanation:

Manipulate the triangle so angle A measures approximately 92°.

Manipulate the triangle so angle B measures approximately 51°.

Notice the straight line p.

What must the measurement of angle C be for p to remain a straight line?

Angle C should measure approximately 37 Degrees

There is angle C should measure approximately 37° for line p to remain a straight line.

What are the vertical angles?

When two lines intersect at a location, vertical angles are generated. They are always equal to each other.

As we know that a straight line, the sum of the angles is equal to 180°.

So, when angle A measures approximately 92° and angle B measures approximately 51°,

Then, the measurement of angle C must be 180° - 92° - 51° = 37° in order to keep line p a straight line.

Thus, angle C should measure approximately 37° for line p to remain a straight line.

The isosceles triangle below is rotated along the blue dashed line going through the center. Find the volume of the cone formed by doing this rotation. Round your answer to the nearest tenth.

Answers

Answer:

47.1

Step-by-step explanation:

Sorry if its wrong

The cone's volume is approximately 47.1 cubic centimeters, obtained by rotating the provided isosceles triangle along its central blue axis.

The volume of a cone is calculated by the following formula:

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

where r is the radius of the base and h is the height of the cone.

In this case, the height is simply the height of the triangle, which is 5 cm.

The radius is a bit trickier.  

Notice that the blue dashed line bisects the base of the triangle.  Therefore, the radius is half the length of the base, which is 6 cm / 2 = 3 cm.

Substituting these values into the formula, we get:

[tex]$V = \frac{1}{3}\pi (3\text{ cm})^2 (5\text{ cm})$[/tex]

[tex]$V = 15\pi \text{ cm}^3$[/tex]

Rounding this to the nearest tenth, we get:

[tex]$V = 47.1 \text{ cm}^3$[/tex]

Therefore, the volume of the cone is approximately 47.1 cubic centimeters.

Consider the functions:

h(x) = (x + 3)2 + 4


Which statement describes the relationship between the minimums of the functions?


a The minimum of h(x) is farther left and up than the minimum of f(x) and g(x).

b The minimum of g(x) is in the fourth quadrant. The minimum of h(x) is in the first quadrant.

c The minimum of g(x) is farther right and down than the minimum of f(x) and h(x).

d The minimum of g(x) is in the second quadrant. The minimum of h(x) is in the first quadrant.

Answers

Answer:

a The minimum of h(x) is farther left and up than the minimum of f(x) and g(x)

Step-by-step explanation:

To know the relation between the minima of the functions you calculate the minima by using the derivative:

[tex]f'(x)=2x\\\\g'(x)=2(x+1)\\\\h'(x)=2(x+3)[/tex]

to find the values of x you equal the derivative of the function to zero:

[tex]f'(x)=0;\ x=0;\\\\g'(x)=0; \ x=-1;\\\\h'(x)=0;\ x=-3;[/tex]

by evaluating this values of x you obtain the coordinates of the minima:

[tex]f(0)=0\\\\g(-1)=-2\\\\h(-3)=4[/tex]

hence, the coordinates will be:

f -> (0,0)

g -> (-1,-2)

h -> (-3,4)

hence, the relation is:

a The minimum of h(x) is farther left and up than the minimum of f(x) and g(x).

In triangle PQR, what is the triangle Q? Please answer as fast as possible! 100 POINTS!!!

Answers

Answer:

105 degrees

Step-by-step explanation:

The sum of the angles in a triangle add up to 180. Although we don't the know the numerical values of the angles, we can create an equation with the given expressions:

<P + <Q + <R = 180

(6x + 5) + (11x - 5) + x = 180

18x = 180

x = 10

Now, plug this value of x into the expression for Q:

<Q = 11x - 5 = 11 * 10 - 5 = 110 - 5 = 105

Thus, the measure of angle Q is 105 degrees.

Hope this helps!

Answer:

105 degrees

Step-by-step explanation:

The angles in a triangle must add to 180 degrees

<Q +<P + <R =180

We know <Q is 11x-5, <P is 6x+5 and <R is x, so we can substitute them in

11x-5+6x+5+x=180

Combine like terms

11x+6x+x +5 -5 =180

18x=180

Divide both sides by 18

x=10

Now we know x, and we can substitute that in to to find <Q

<Q=11x-5

<Q=11(10)-5

<Q=110-5

<Q=105

What is Symmetry?

In mathematics, symmetry has a more precise definition, and is usually used to refer to an object that is invariant under some transformations; including translation, reflection, rotation or scaling.

What is Graph?

A graph is a structure amounting to a set of objects in which some pairs of the objects are in some sense related.

Here,

The graph of r = -3 + 5cosθ is symmetric about the x axis only

Also when we plot the graph we can say that it is symmetric about x axis only.

Answers

Answer:

A) 288 [tex]cm^{3\\}[/tex]

Step-by-step explanation:

The Volume of the figure is 288 cm³.

What is Volume?

Volume is a three-dimensional quantity used to calculate a solid shape's capacity. That means that the volume of a closed form determines how much three-dimensional space it can fill.

Given:

Base edges = 4 cm x 4 cm

Height = 1 cm

So, Volume = area of the base x height

For Figure 1:

Volume of figure1

=(4x4)x 10

=160
