Answer:

24x²

Step-by-step explanation:

6 x 4x² = 24(x)(x) = 24x²

Answer:

21.6

Step-by-step explanation:

Connect U and X, V and Y

Note ∠XUW = ∠VYW (facing same arc VX) and ∠W = ∠W

so ΔUXW ~ ΔVYW

then VW : YW = XW : UW

VW : YW = (YW - YX) : (UV + VW)

22 : 40 = (40 - 16) : (UV + 22)

11: 20 = 24 : (UV + 22)

11 * ( UV + 22) = 20 * 24

11* UV + 242 = 480

11 * UV = 480 - 242 = 238

so UV = 238/11 = 21.6

Answer:

Multiply 54 by 6

Step-by-step explanation:

Remember the Order of Operations:

Parentheses

Exponents

Multiplication/Division (Whichever comes first)

Addition/Subtraction (Whichever comes first)

In this case, we can start by looking inside of the parentheses.

There are two signs; addition and multiplication.

Now we look back to the order of operations (PEMDAS), and see that multiplication comes before addition, therefore you should first multiply 54 by 6.

Answer:

We use a variety of different notations to express the derivative of a function. In (Figure) we showed that if f(x)=x^2-2x, then f^{\prime}(x)=2x-2. If we had expressed this function in the form y=x^2-2x, we could have expressed the derivative as y^{\prime}=2x-2 or \frac{dy}{dx}=2x-2. We could have conveyed the same information by writing \frac{d}{dx}(x^2-2x)=2x-2. Thus, for the function y=f(x), each of the following notations represents the derivative of f(x):

f^{\prime}(x), \, \frac{dy}{dx}, \, y^{\prime}, \, \frac{d}{dx}(f(x)).

In place of f^{\prime}(a) we may also use \frac{dy}{dx}\Big|_{x=a} Use of the \frac{dy}{dx} notation (called Leibniz notation) is quite common in engineering and physics. To understand this notation better, recall that the derivative of a function at a point is the limit of the slopes of secant lines as the secant lines approach the tangent line. The slopes of these secant lines are often expressed in the form \frac{\Delta y}{\Delta x} where \Delta y is the difference in the y values corresponding to the difference in the x values, which are expressed as \Delta x ((Figure)). Thus the derivative, which can be thought of as the instantaneous rate of change of y with respect to x, is expressed as

\frac{dy}{dx}=\underset{\Delta x\to 0}{\lim}\frac{\Delta y}{\Delta x}.

Answer:

45 years

Step-by-step explanation:

Let the sum be x and CI=2x

We know that

CI=P(1+100R)T

2x=x(1+100R) ^15

(1+100R)^15=2                

Let m be the number of years.

Therefore,

x(1+100R)m=8x

(1+100R)m=23

(1+100R)m=[(1+100R)^15]3          

From eqn(1)

(1+100R)m=(1+100R)45

On comparing both power, we get

m=45 years

Answer:

yellow = 33.3 %

green = 20%

orange = 30%

red = 16.6%

Step-by-step explanation:

all in all there are 30 cards

10 ➗ 30 = 0.333 = 33.3%

6 ➗ 30 = 0.20 = 20%

9 ➗ 30 = 0.30 = 30%

5 ➗ 30 = 0.166 = 16.6%

The term "dilation" refers to a transformation. The height of the pre-image is 24.4 mm.

The term "dilation" refers to a transformation that is used to downsize an item. Dilation is a technique for making items appear bigger or smaller. The picture produced by this transformation is identical to the original shape.

Let the dilation factor of the trapezoid be x.

Now, if we write the area of the pre-image trapezoid, it can be written as,

[tex]\text{Area of trapezoid} = \dfrac{(a+b)}{2}h = 49\rm\ mm^2[/tex]

As we know the dilation is applicable to dimensions, therefore, the area of the trapezoid which is the image can be written as,

[tex]\text{Area of Image trapezoid} = \dfrac{(ax+bx)}{2}hx[/tex]

                                      [tex]= \dfrac{x(a+b)}{2}hx\\\\=\dfrac{(a+b)}{2}h\cdot x^2\\\\=49\cdot x^2[/tex]                  

Now, if we calculate the scale factor(x) of the dilation we will get,

[tex]{\text{Area of trapezoid}}={\text{Area of Image trapezoid}}\\\\x^2 \cdot 49 = 784\\\\x = 4[/tex]

Further, the scale factor applied to the height of the image can be written as,

The height of the Image = 4 × Height of pre-image

                                          = 4 × 6.1 = 24.4 mm

Hence, the height of the pre-image is 24.4 mm.

Answer:

Step-by-step explanation: I took the quiz

Answer:  1360 in^2

Step-by-step explanation:

Each of the four rectangles on the side is 20x12 inches. Therefore, the total area of the 4 rectangles is 4*20*12 = 960 in^2.

The area of the square in the middle is 20*20 = 400 in^2.

Therefore, the total area = 960 + 400 in^2 = 1360 in^2

Step-by-step explanation:

we have a right-angled triangle here.

there is the ground distance boat to lighthouse.

there is the height of the lighthouse = 141 ft.

and there is the line of sight boat to lighthouse light.

the angle at the boat is 12°.

the angle at the lighthouse bottom is 90°.

therefore, the angle at the lighthouse light is 180 - 90 - 12 = 78°

we use the law of sine to solve this.

a/sin(A) = b/sin(B) = c/sin(C)

with the sides and correlated angles being always opposite.

so, we have here

141/sin(12) = ground distance/sin(78)

ground distance = 141×sin(78)/sin(12) = 663.3528454... ft

≈ 663.35 ft

The approximate angle to the other two landmarks from the Empire State Building is 129.868°

Cosine rule is used to show the relationship between the sides and angles of a triangle. It is given by:

a² = b² + b² - 2bc*cosA

Where a, b, c are the sides and A is the angle opposite to side A.

Let A represent the angle to the other two landmarks from the Empire State Building. Hence:

2² = 1.3² + 0.9² - 2(1.3)(0.9)cosA

A = 129.868°

Answer: 2) 2/7,  11/72   3)  2 2/5 licorice pieces

Step-by-step explanation:

2)

A fraction of another fraction is essentially the two fractions multiplied.

Therefore, 2/3 of 3/7 = (2*3)/(3*7) = 6/21 = 2/7

1/6 of 11/12 = (1*11)/(6*12) = 11/72

3) If the licorice is divided equally, that means each person would get 12/5 of licorice pieces. 12/5 as a mixed number would become 2 2/5.

Answer:
