Answer:

x = 16[tex]\sqrt{3}[/tex]

y = 8[tex]\sqrt{3}[/tex]

Step-by-step explanation:

For this type of equation, you are going to use the following trigonometric signs tangent and cosine.  Tangent is used for the y-variable and cosine is used for the x-variable.  For the y-variable, it is 24 tan 30 to get 8 root 3 as your answer.  For the x-variable, you would get ([tex]\sqrt{3}[/tex] / 2)x = 24.  Divide that root number to get 16[tex]\sqrt{3}[/tex] as your x variable.

Answer: 16 sqrt 3. 8 sqrt 3

Complete Question

Maurice takes a roast out of the oven when the internal temperature of the roast is 165°F. After 10 minutes, the temperature of the roast drops to 145°F.

The temperature of the room is 72°F.

How long does it take for the temperature of the roast to drop to 120°F?

Answer:

27.3143 minutes

Step-by-step explanation:

Using the Newton's law of cooling: The formula is given as:

T (t) = T₀ + T₁ e^ (rt)

Where

T₀ = Original temperature of the room (°F) ; 72°F

T₁ = Temperature of the roast (°F)

This is calculated as:

165 - 72 =93°F

r = Rate of cooling (°F/min)

t = time (min)

Substituting the values, we can obtain:

T (t) = 72 + 93 e ^rt

Step 1

We solve for r

From the question, we know that: the temperature dropped to 145°F after 10 minutes,

t =10 mins and T(10) = 145 °F

Substituting

T(10) = 72 +93 e^10r

145 = 72 + 93 e^10r

145 - 72 = 93 e^10r

Divide both sides by 93

(145-72)/93 = e^(10r)

We take the natural logarithm of both the left and right hand sides

In [(145-72)/93 ] = In (e^10r)

In [(145-72)/93 ] = 10r

-0.24214 =10r

r = -0.24214/10

r = -0.02421 °F/min

Substituting into

-0.02421 °F/min for r in the Equation below

T (t) = 72 + 93 e ^rt

T (t) = 72 + 93 e^ (-0.024214t)

To find the time taken to reach 120°F, we substitute into equation

120 = 72 +93 e^(-0.024214 ×t)

(120-72)= 93 e^ (-0.024214t)

Divide bother sides by 93

[(120-72)/93] = e^-0.024214t

We take the natural logarithm of both sides

In[(120-72)/93] = In(e^-0.024214t)

-0.66139 = -0.024214t

Divide both sides by -0.024214t

t = -0.66139/ -0.024214

t =27.3143 minutes

The total area of office that the small business needs to carpet is 174ft^2

The area of the rectangle is the region enclosed by the perimeter of the rectangle and is equal to product of length and width. The area of a rectangle (A) is the product of its length 'a' and width or breadth 'b'.

So, the Area of Rectangle = (a × b) square units.

The area of a rectangle is length ✕ width.

So, width = area/length

length = 7.2 ft

width = 5.8ftnumber of office = 4

Area of one office = 7.2 * 5.8 Area of one office = 43.5ft^2

The total area of the four offices will be 43.5 * 4 = 174ft^2

Given that,

Length of 4 pieces of wood are 16.75 inches, 9 inches, 24.25 inches, and 12.5 inches.

To find,

The length of the strip of wood.

Solution,

Mark glues together four pieces of wood to make one long strip.

Long strip = The sum of 16.75 inches, 9 inches, 24.25 inches, and 12.5 inches.

L = 16.75 + 9 + 24.25 + 12.5

= 62.5 inches

Hence, the strip of wood is 62.5 inches long.

this is the answere and the explanation.

By substituting x = -1/2, the expression [tex]\(f(x) = \frac{\sqrt{2x} + 3}{6x - 5}\)[/tex] can be simplified to[tex]f(x) = \(f(-\frac{1}{2}) = \frac{\sqrt{3 - \sqrt{2}}}{-8}\).[/tex].

To find [tex]\(f(-\frac{1}{2})\)[/tex], substitute [tex]\(-\frac{1}{2}\)[/tex] into the function f(x):

[tex]\(f(-\frac{1}{2}) = \frac{\sqrt{2 \cdot (-\frac{1}{2}) + 3}}{6 \cdot (-\frac{1}{2}) - 5}\)[/tex]

Now, simplify the expression inside the square root:

[tex]\(f(-\frac{1}{2}) = \frac{\sqrt{-\sqrt{2} + 3}}{-3 - 5}\)\\\(f(-\frac{1}{2}) = \frac{\sqrt{3 - \sqrt{2}}}{-8}\)[/tex]

Answer:

D) is the answer

Step-by-step explanation:

ohh ok i understand TUV is (x,y)

so (x+8,y-3) is the T'U'V

so subtract 8 and add 3 to this translation

(x-8,y+3)

looking at U

t goes to (10,-5)

and that is the only one so the answer is D

The coordinates or TUV are  (-6,-3),(-1,6),(0,-2), the correct option is C.

(SCALING ZOOMING SIMILAR FIGURES)

Suppose a figure (pre image) is dilated (dilated image) by scale factor of k.

So, if a side of the figure is of length L units, and that of its similar figure is of M units, then:

L = k × M

where 'k' will be called as scale factor.

The linear things grow linearly like length, height etc.

The quantities which are squares or multiple of linear things twice grow by square of scale factor. Thus, we need to multiply or divide by k² to get each other corresponding quantity from their similar figures' quantities.

So area of first figure = k² × area of second figure

Similarly,

Volume of first figure = k³ × volume of second figure.

It is because we will need to multiply 3 linear quantities to get volume, which results in k getting multiplied 3 times, thus, cubed.

Given;

TUV is translated to image T'U'V , as shown below , by the rule (x,y) -> (x+8, y-3)

Coordinates of T'U'V; (2,-6),(7,3),(8,-5)

Now, coordinates of TUV;

T coordinate=(-6,-3)

U coordinate=(-1,6)

V coordinate=(0,-2)

Therefore, coordinates before dilation will be (-6,-3),(-1,6),(0,-2)
