Answer:

The answer is X equals 17

Answer:

Point B is (1, 2)

Step-by-step explanation:

Let us revise the rule of the translations

∵ Point A = (-2, 0)

∵ T (3, 2) → A = B

→ By using the 1st and 3rd rules above, A is translated 3 units right and 2

  units up to get B

∴ T (x, y) → (x + 3, y + 2)

∵ A = (x, y)

∵ x = -2 and y = 0

∴ B = (-2 + 3, 0 + 2)

∴ B = (1, 2)

∴ Point B is (1, 2)

Answer:

For a rectangular solid with:

width = w

length = l

height = h

The volume is equal to:

V = w*l*h

in this case we know that:

width = w.

"length of 7 more than the width"

l = w + 7.

"a height that is equivalent to 15 decreased by 3 times the width."

h = 15 - 3*w

Then the volume will be:

V = w*l*h = w*(w + 7)*(15 - 3w) = (w^2 + 7*w)*(15 - 3*w)

V =  ( -3*w^3 + 15*w^2 + 105*w - 21*w^2)

V = (-3*w^3 - 6*w^2 + 105*w)

Now, the maximum volume will be for the value of w such that:

V'(w) = 0.

and:

V''(W) < 0

Where:

dV/dw = V'(w).

dV'/dw = V''(w)

Then first we need to differentiate the equation for the volume.

V'(w) = dV/dw = ( 3*(-3*w^2) + 2*(-6*w) + 105)

V'(w) = -9*w^2 - 12*w + 105.

Then we need to find the solution for:

-9*w^2 - 12*w + 105 = 0.

We can use the Bhaskara formula, and we will get:

[tex]w = \frac{+12 +-\sqrt{(-12)^2 - 4*(-9)*105} }{2*-9} = \frac{+12 +- 62.6}{-18}[/tex]

Then the two solutions are:

w₁ = (+12 - 62.6)/(-18) = 2.81

w₂ = (+12 + 62.6)/(-18) = -15.5

But we can not have a negative width, so we can just discard the second solution.

Now let's check the second condition for the maximum, we must have:

V''(2.81) < 0.

V'' = dV'/dw = 2*(-9*w) - 12 = -18*w - 12

V''(2.81) = -18*2.81 - 12 = -62.58 < 0 .

Then the volume is maximized when w = 2.81, and the maximum volume will be:

V(2.81) =  (-3*(2.81)^3 - 6*(2.81)^2 + 105*2.81) = 180.1

56n+24 = 24 + 7n

49n + 24 = 24

49n = 0

n = 0

solution

Answer:

n = 0

Step-by-step explanation:

8(7n + 3) = 24 +7n

1. distribute the 8 inside the paranthesis

56n + 24 = 24 + 7n

2. subtract 24 from both sides

56n = 7n

3. subtract 7n from both sides

49n = 0

n = 0

Answer:

Yes

Step-by-step explanation:

Yes, actually. If we graph the data table we see that the function actually passes the vertical line test. Despite the same output occurring for different inputs, a single x-value does not have multiple y-values, which would mean it wasn't a function.

The measure of angle FDE (m ∠FDE) is m ∠FDE = 92°

From the question, we are to find the measure of angle FDE

In the given diagram, we can observe that

∠BDC + ∠FDB = 180° (Sum of angles on a line segment)

From the given information,

m ∠BDC = (8x+12)°

and

m ∠FDB = (12x−32)°,

Thus,

(8x+12)° + (12x−32)° = 180°

8x + 12 + 12x - 32 = 180

8x + 12x = 180 + 32 - 12

20x = 200

x = 200/20

x = 10

Now, we are to determine the measure of angle FDE (m ∠FDE)

In the diagram,

∠FDE = ∠BDC (Vertically opposite angles)

Thus,

m ∠FDE = (8x+12)°

Put the value of x into the equation

m ∠FDE = (8(10)+12)°

m ∠FDE = (80+12)°

m ∠FDE = 92°

Hence, the measure of angle FDE (m ∠FDE) is m ∠FDE = 92°

Here is the complete question:

Refer to the figure.

If m∠BDC=(8x+12)° and m∠FDB=(12x−32)°, find m∠FDE.

We are to express a given fraction into a decimal.

A fraction is the ratio of two numbers usually with a numerator and the denominator separated by a horizontal bar in between them.

On the contrary, the division of the fraction will result in a decimal number(a standard system of representing fractions)

To divide;

[tex]\mathbf{=\dfrac{15}{27}}[/tex]

= 0.5556

Therefore, we can conclude that the fraction 15/27 in decimal = 0.5556
