Answer:

\((x + 2)^{2} + y^{2} = 45\)

Step-by-step explanation:

The radius (r) of the circle is the distance between (-2, 0) and (-5, -6)

r = \(\sqrt{(-2 + 5)^{2} + (0 + 6)^{2} } = \sqrt{3^{2} + 6^{2} } = \sqrt{9 + 36} = \sqrt{45}\)

\(r^{2}\) = 45

\((x + 2)^{2} + y^{2} = 45\) is the equation of the circle

The area of triangle ADE is,

⇒ A = 48 square units

We have to given that,

In the diagram , DE is a midsegment of triangle ABC.

And, The area of triangle ABC is 96 square units

Now, We know that,

Since DE is a midsegment of triangle ABC, it is parallel to AB and half the length of AB. Therefore, DE is half the length of AB.

Hence, the area of triangle ADE is half the area of triangle ABC,

That is,

A = 96 / 2

A = 48 square units

Thus, The area of triangle ADE is,

⇒ A = 48 square units

Answer:

Step-by-step explanation:

The general equation for a direct variation is y = k*x

So your first step (usually) is to find k

y = k x

when x = 4

then y = 50

Now you can find the value of y when x = 2

y = 12.5 * 2

y = 25

Answer:

12.5% chance

Step-by-step explanation:

First a spinner has a 25% chance of landing on a one, then a tails is a 50% chance, subtract devide 25 by two and you get 12.5.

The area of Sam's rectangle with the given length and width is 12 sq. cm.

A mixed fraction is one that has both its quotient and remainder represented. A mixed fraction like 2 1/3 is one where the remainder is 1 and the quotient is 2. Hence, a mixed fraction is made up of both a full number and a correct fraction.

The correct fraction's denominator is multiplied by the whole number that is attached before the numerator is added in order to turn a mixed fraction into an improper fraction.

The length of the rectangle is 4 1/2 = 9/2 cm.

The width of the rectangle is 2 2/3 = 8/3 cm.

The area of the rectangle is:

A = (l)(b)

A = (9/2)(8/3)

A = 12 sq. cm.

Hence, the area of the rectangle is 12 sq. cm.

I have an answer and explanation but I can't type so search up the question you asked and you should get an answer and explanation from s0cratic.

The required equation is g(x) = 10(3)x which is the correct answer would be an option (A).

The graph of g(x) is obtained by stretching the graph of f(x) vertically by a factor of 2.

Since the vertical stretch of a graph multiplies the y-coordinates of each point on the graph by a constant factor, the equation of g(x) must be obtained by multiplying the y-coordinate of each point on the graph of f(x) by 2.

In the given equation f(x) = 5(3)x, the y-coordinate of each point on the graph of f(x) is 5(3)x.

Thus, to stretch the graph of f(x) vertically by a factor of 2, we need to multiply this y-coordinate by 2 to get the y-coordinate of the corresponding point on the graph of g(x). This gives us the following equation for g(x):

⇒ g(x) = 2 × 5(3)x = 10(3)x

Therefore, the required equation is g(x) = 10(3)x.

We have the equation a)

The domain of a function is the set of all possible inputs for the function. In this case, as a root can not take a negative number, x can not take negative values. The domain would be from 0 to positive infinite.

The intercepts are calculated:

Intercept in y-axis y=0, we replace in the equation and solve for x:

Intercept in x-axis x=0, we replace in the equation and solve for y:

Only one intercept in the parabola (0,0)

Symmetry:

We check for symmetry about the x-axis, replacing the y for -y:

This is identical to the original equation, so we have symmetry about the x-axis.

Now we check for symmetry about the y-axis, replacing in the equation the x for -x:

This is not identical to the original equation since the sign of 8x changes to negative, this means there is no symmetry about the y-axis.

Using the scale factor of the similar triangles, the height of the tree is: 75 ft.

The scale factor of similar triangles is the ratio of the lengths of corresponding sides. It represents the relationship between the size of two similar triangles. If the scale factor is "k", then any side length of the larger triangle is "k" times the length of the corresponding side in the smaller triangle.

The diagram given shows that the bigger triangle is a copy of the smaller triangle that is enlarged by 2. This means the scale factor is 2.

Therefore: the height of the tree = 150/2 = 75 ft.

The equation that is equivalent to P = B + Brz is:

r = (P - B) / Bz

To see why, we can rearrange the original equation as follows:

P = B + Brz

P - B = Brz

(P - B) / Bz = r

Therefore, r = (P - B) / Bz is equivalent to P = B + Brz.

Now let's check the given options:

x = P/Br + 1/r

This equation is not equivalent to P = B + Brz.

r = (P - B) / Bz

This is the correct equation that is equivalent to P = B + Brz.

r = Bz / (P - B)

This equation is not equivalent to P = B + Brz.

B = P / (rz + 1)

This equation is not equivalent to P = B + Brz.

The amount of force used to pull the cart from 60 N to 90 N, the new acceleration of the cart is, 1.5 m/s²

The definition of force is the pushing or pulling of anything. Push and pull are the result of two things interacting with one another. Stretch and crush are two more phrases that can be used to describe force.

Formula of force,

F = ma

Given that,

A man pulled a cart filled with stones that had a total mass of 60 kg

He increased the amount of force used to pull the cart from 60 N to 90 N

New acceleration of cart = ?

F  = ma

Old acceleration,

60  = 60a

a   =  1 m/s²

New acceleration,

90 = 60a

a   = 90/60

a   =  3/2

a   =  1.5 m/s²

Hence, the new acceleration is 1.5 m/s²

The rank of the matrix is 3, since there are three linearly independent rows.

The rank of a matrix is the maximum number of linearly independent rows or columns in the matrix. It is denoted by the symbol "rank(A)" for a matrix A.

To find the rank of the matrix:

[-2, -1, -3, -1] [ 1, 2, -3, -1] [ 1, 0, 1, 1] [ 0, 1, 1, -1]

We can perform row operations to reduce the matrix to row echelon form, which will help us determine the rank.

\(R_2 = R_2 + 2R_1 R_3 = R_3 + 2R_1 R_4 = R_4 + R_2\)

This gives us the following matrix:

[-2, -1, -3, -1] [ 0, 0, -9, -3] [ 0, -1, -1, 1] [ 0, 0, -4, -4]

We can see that the third row is not a linear combination of the first two rows, and the fourth row is not a linear combination of the first three rows. Therefore, the rank of the matrix is 3, since there are three linearly independent rows.

Answer:

Step-by-step explanation:

1. The trigonometric ratios are given as follows:

2. The equation to solve for x is given as follows: sin(52º) = x/13.

3. Two equations to solve for m are given as follows:

4. The length of the hypotenuse of the triangle is given as follows: 7.9 inches.

5. The lengths are given as follows:

The three trigonometric ratios are given as follows:

In the second problem, we have that the side x is opposite to the angle of 52º, while the hypotenuse is of 13, hence the equation to solve for x is given as follows:

sin(52º) = x/13.

In item 3, the Pythagorean Theorem is used to solve for m, as follows:

n² + m² = l².

m² = l² - n²

m = square root (l² - n²).

In item 4, we have that the angle opposite to the leg of length 7 inches is of 62º, hence the hypotenuse is given as follows:

sin(62º) = 7/h

h = 7/sin(62º)

h = 7.9 inches.

The length BD in item 5 is obtained as follows:

cos(30º) = BD/5

BD = 5 x cos (30º)

BD = 4.3 cm.

Then the length BC is calculated as follows:

sin(22º) = 4.3/BC

BC = 4.3/sin(22º)

BC = 11.5 cm.
