$32000-$4800=$27200

Answer:

We have point P(-3,-6).

Step-by-step explanation:

We want to find a point P(x,y).

Since it is on the directed line segment AB in the ratio 3:4, it means that:

\(P - A = \frac{3}{3+4}(B - A)\)

So

\(P - A = \frac{3}{7}(B-A)\)

We apply this to both the x-coordinate and y-coordinate of P.

x-coordinate:

x-coordinate of A: -9

x-coordinate of B: 5

x-coordinate of P: x

So

\(P - A = \frac{3}{7}(B-A)\)

\(x - (-9) = \frac{3}{7}(5-(-9))\)

\(x + 9 = \frac{3}{7} \times 14\)

\(x + 9 = 6\)

\(x = -3\)

y-coordinate:

y-coordinate of A: -9

y-coordinate of B: -2

y-coordinate of P: y

So

\(P - A = \frac{3}{7}(B-A)\)

\(y - (-9) = \frac{3}{7}(-2-(-9))\)

\(y + 9 = \frac{3}{7} \times 7\)

\(y + 9 = 3\)

\(y = -6\)

We have point P(-3,-6).

Answer:

We are told that circle C has center (-4, 6) and a radius of 2.

We are told that circle D has center (6, -2) and a radius of 4.

If we move circle C's center ten units to the right and eight units down, the new center would be at (-4 + 10), (6 - 8) = (6, -2). So step 1 in the informal proof checks out - the centers are the same (which is the definition of concentric) and the shifts are right.

Let's look at our circles. Circle C has a radius of 2 and is inside circle D, whose radius is 4. Between Circle C and Circle D, the radii have a 1:2 ratio, as seen below:

If we dilate circle C by a factor of 2, it means we are expanding it and doubling it. Our circle has that 1:2 ratio, and doubling both sides gives us 2:4. The second step checks out.

Translated objects (or those that you shift) can be congruent, and dilated objects are used with similarity (where you stretch and squeeze). The third step checks out.

Thus, the argument is correct and the last choice is best.

Answer:

a^3b^2

Step-by-step explanation:

Recall that the first law of indices states that

a^x * a^y = a^(x+y)

Hence the expression  (a.a.a)(b.b)

= a^(1+1+1) * b^(1+1)

= a^3b^2

This is the product of a raised to the power of 3 and b raised to the power of 2

The 0.0035 hr⁻¹ first-order degradation rate constant in the 40 °C, 1.0 mg/ml solution, where R = 1.987 cal/mol/degree and 2,000 cal/mol activation energy indicates;

a. The rate constant for first-order degradation of N₂O₂ at room temperature is approximately 4.12595 × 10⁻² hr⁻¹

A first order reaction is one that has a rate that varies linearly with the concentration of one reactant

The given parameters are;

Temperature of the solution = 40°C

T₁ = 40 °C + 273.15 = 313.15 K

The rate constant, K₁ = 0.00351 hr⁻¹

Concentration of the solution = 1.0 mg/ml

Activation energy, Eₐ = 2000 Cal/mol

R = 1.987 cal/mol/degree

The formula by which the rate constant can be found is presented as follows;

\(log\dfrac{k_2}{k_1} =\dfrac{E_a}{2.303\times R} \times \dfrac{T_2-T_1}{T_1\cdot T_2}\)

a. Room temperature = 25 °C

T₂ = 25 °C + 273.15 = 298.15 K

Therefore;

\(log\dfrac{k_2}{0.00351} =\dfrac{2000}{2.303\times 1.987} \times \dfrac{313.15-298.15}{313.15 \times 298.15}\)

\(k_2=0.00351 \times 10^{\left(\dfrac{2000}{2.303\times 1.987} \times \dfrac{313.15-298.15}{313.15 \times 298.15}\right)} \approx 4.12595\times 10^{-2}\)

x = -3 + √117

x = -3 - √117

Step-by-step explanation:

So the equation is x(x+6)=108

first you gotta simplify

x*x + x*6 = 108

x^2 + 6x = 108

x^2 + 6x - 108 = 0

using the quadratic formula:

x = (-b ± √(b^2 - 4ac)) / (2a) with a=1, b=6 and c=-108

Answer:

9 = h

Step-by-step explanation:

The formula of finding the volume of a pyramid is:

V = l * w(h / 3)

We know that Volume is 36, base or Length is 4 and the Width is 3, therefore;

36 = 4 * 3 (h/3)

36 = 12 * h/3

36/12 = h/3

3 = h/3

3(3) = h

9 = h

Therefore the height or h of the pyramid is 9cm

Let's find the seconds as an improper fraction:

He ran 100 meters in 48/5 seconds or 9.6 seconds. To find the speed in meters per second we have to divide the distance (in meters) by the time (in seconds):

The average speed is 125/12 m/s (or 10.42 m/s, rounded to the nearest hundredth)

In mixed numbers the speed is 10 5/12 m/s

Answer:

[m] slope = -2

[b] y-intercept = -1 ; (0, -1)

[y = mx + b] slope-intercept = -2x – 1

Step-by-step explanation:

Given the algebraic equation 6x + 3y = -3 currently in standard form:

Ax + By = C →

By = C – Ax →

By = -Ax + C →

y = -Ax / B + C / B →

y = (-A / B)x + (C / B) →

y = mx + b →

m = -A / B. b = C / B.

6x + 3y = -3

↓ ↓ ↓

A = 6. B = 3. C = -3.

[Substitute]

m = -A / B. b = C / B

m = -(6) / (3). b = (-3) / (3)

↓ ↓

m = -2. b = -1.

↓. ↓

Slope = -2. y-intercept = -1.

_______________________

Slope is ∆y/∆x [change in y over the change in x] = y2 – y1 / x2 – x1.

The y-intercept is the point where x is 0.

The easiest way to determine this is to substitute 0 in for x in an equation and solve for y.

This means that the y intercept in coordinate form is (0, b).

Before carrying out rotation transformation, the coordinates of the vertices of the pre-image are;

A (3, -6)

B(1, 2)

C (7, -1).

We are given the coordinates of the transformed image as:

A'(6, 3),

B'(–2, 1),

C'(1, 7).

We need to find the coordinates of the pre-image A, B and C.

The rule for rotation of 90° about the origin is (x,y) ---> (-y,x).

But we need to find the coordinates of the vertices of the pre-image.

So, we need to apply rule (-y,x) ---->(x,y).

Applying the 90 degrees clockwise rotation rule,

A'(6, 3) -----> A (3, -6)

B'(–2, 1) -----> B(1, 2)

C'(1,7) -----> C (7, -1).

Therefore, coordinates of the vertices of the pre-image are

A (3, -6)

B(1, 2)

C (7, -1).

Step-by-step explanation:

The number of miles (m) between the two cities as represented in the equation given 2[(4m * 3.5) / 400] = 171.5 is 2450 miles

The definition of an equation is a mathematical statement that shows that two mathematical expressions are equal. For instance, 3x + 5 = 14 is an equation, in which 3x + 5 and 14 are two expressions separated by an ‘equal’ sign. The most basic and simple algebraic equations consist of one or more variables in math.

In the equation given;

2[(4m * 3.5) / 400] = 171.5

Using changing the subject of formula to find the miles travelled;

2[(4m * 3.5) / 400] = 171.5

28m / 400 = 171.5

28m = 400 * 171.5

28m = 68600

m = 68600 / 28

m = 2450
