tan (40°) = [tex]\frac{x}{100}[/tex]

Step-by-step explanation:

tan [tex]\theta[/tex] = [tex]\frac{opposite}{adjacent}[/tex]

The opposite side to angle B is x. The adjacent side to angle B is 100 ft.

tan (40°) = [tex]\frac{x}{100}[/tex]

Answer:

tan 40° = x/100

Step-by-step explanation:

As, AC is perpendicular and BC is the with respect to angle ABC. So, tan 40° will be use to determine the distance in feet from point C to point A.

tan ABC = perpendicular/base

tan 40° = AC/BC

tan 40° = x/100 feet

Answer:

The greatest possible time taken by Maria is 97.4 seconds.

Step-by-step explanation:

The greatest possible time taken by Maria occurs when she moves at constant rate and is equal to the length of the road divided by the length of the road. That is to say:

[tex]t = \frac{\Delta s}{v}[/tex]

Where:

[tex]\Delta s[/tex] - Length of the road, measured in meters.

[tex]v[/tex] - Average speed, measured in meters per second.

Given that [tex]\Delta s = 380\,m[/tex] and [tex]v = 3.9\,\frac{m}{s}[/tex], the greatest possible time is:

[tex]t = \frac{380\,m}{3.9\,\frac{m}{s} }[/tex]

[tex]t = 97.4\,s[/tex]

The greatest possible time taken by Maria is 97.4 seconds.

Step-by-step explanation:

tan 22= opp/adj

tan 22=30/x

x=30/tan 22

x=30/0.40402=74.3 unit

Answer:

Step-by-step explanation:

In order to solve for x we use tan

tan ∅ = opposite / adjacent

From the question

x is the adjacent

30 is the opposite

So we have

tan 22 = 30/x

x = 30/tan 22

x = 74.25260

Answer:

Option (D)

Step-by-step explanation:

The given expression is,

3x² - 24x + 21

We will factorize the given expression by the following steps,

3x² - 24x + 21

= 3(x² - 8x + 7)

= 3(x² - 7x - x + 7)

= 3[x(x - 7) - 1(x - 7)]

= 3(x - 1)(x - 7)

= (3x - 3)(x - 7)

Therefore, factored form of the given expression is (3x - 3)(x - 7).

Option (D) will be the correct option.

Answer:

Step-by-step explanation:

Given question is incomplete; here is the complete question.

∆ PQR shown in the figure below is transformed into ∆ STU by a dilation with center (0, 0) and a scale factor of 3.

Complete the following tasks,

- Draw ΔSTU on the same set of axes.

- Fill in the coordinates of the vertices of ΔSTU.

- Complete the statement that compares the two triangles.

When ΔPQR is transformed into ΔSTU by a dilation with center (0, 0) and a scale factor of 3,

Rule to followed to get the vertices of ΔSTU,

(x, y) → (3x, 3y)

P(1, 1) → S(3, 3)

Q(3, 2) → T(9, 6)

R(3, 1) → U(9, 3)

Length of QR = 2 - 1 = 1 unit

Length of PQ = [tex]\sqrt{(3-1)^2+(2-1)^2}=\sqrt{5}[/tex] units

Length of PR = 3 - 1 = 2 units

Length of ST = [tex]\sqrt{(9-3)^2+(6-3)^2}=3\sqrt{5}[/tex] units

Length of TU = 6 - 3 = 3 units

Length of SU = 9 - 3 = 6 units

Therefore, ratio of the corresponding sides of ΔPQR and ΔSTU,

[tex]\frac{\text{PQ}}{\text{ST}}=\frac{\text{QR}}{\text{TU}}=\frac{\text{PR}}{\text{SU}}[/tex]

[tex]\frac{\sqrt{5}}{3\sqrt{5}}=\frac{1}{3}=\frac{2}{6}[/tex]

[tex]\frac{1}{3}=\frac{1}{3}=\frac{1}{3}[/tex]

Since ratio of the corresponding sides are same,

Therefore, ΔPQR and ΔSTU are similar.

Answer:

The average rate of change from x=-7 to x=-5 is -3

Step-by-step explanation:

In order to calculate average rate of change we would have to make the following calculation:

According to the given data we have the following:

x=-7 so, f(-7) is to be calculated in the graph y

x=-5 so, f(-5) is to be calculated in the graph y

Therefore, average rate of change=f(-5)-f(-7)/-5-(-7)

average rate of change=3-9/2

average rate of change=-6/2

average rate of change=-3

The average rate of change from x=-7 to x=-5 is -3

The average rate of change of a function is the unit change of the function.

The average rate of change from x = -7 to x = -5 is -3

The average rate of change is calculated as:

[tex]\mathbf{f'(x) = \frac{f(b) - f(a)}{b - a}}[/tex]

The interval is given as: x = -7 to x = -5.

This means that:

a = -5 and b = -7

So, we have:

[tex]\mathbf{f'(x) = \frac{f(-7) - f(-5)}{-7 - -5}}[/tex]

This gives

[tex]\mathbf{f'(x) = \frac{f(-7) - f(-5)}{-2}}[/tex]

From the graph

f(-7) = 9 and f(-5) = 3.

So, we have:

[tex]\mathbf{f'(x) = \frac{9 - 3}{-2}}[/tex]

Subtract

[tex]\mathbf{f'(x) = \frac{6}{-2}}[/tex]

Divide

[tex]\mathbf{f'(x) = -3}[/tex]

Hence, the average rate of change from x = -7 to x = -5 is -3

Answer:

c. translation (x,y) -> (x-4, y-1) followed by reflection about y=0

Step-by-step explanation:

The strategy is to translate B to E then reflect about the x-axis (y=0)

From B to E, the process is

(x,y) -> (x-4, y-1)

Therefore it is a translation (x,y) -> (x-4, y-1) followed by reflection about y=0

Answer:  A) The log parent function has negative values in the range.

Step-by-step explanation:

The domain of y = ln (x)  is D: x > 0

The domain of y = [tex]\sqrtx[/tex][tex]\sqrt x[/tex]  is  D: x ≥ 0

The range of y = ln (x)  is: R: -∞ < y < ∞

So the only valid option is A because the range of a log function contains negative y-values when 0 < x < 1.

Answer:

                [tex]8\frac23\ cm^2[/tex]

Step-by-step explanation:

sector of the circle if the angle at the center is 150° means  [tex]\frac{150^o}{360^o}[/tex] of full circle of given radius

area of a circle of given radius R is:  πR²

so area of given sector:

[tex]A=\dfrac{150^o}{360^o}\cdot \pi\cdot8^2=\dfrac5{12}\cdot3.1\cdot64=82,(6)=8\frac23\ cm^2[/tex]

The area of a sector of the circle if the angle at the center is 150° is 82.67 square centimeter.

A circle is a locus of a point whose distance always remains constant from a given specific point. The general equation is -

x² + y² = r²      (for circle centered at origin)

Given is a circle has a radius of 8 cm.

The area of the sector subtending the angle 150° at center is -

A = (150/360) x 3.1 x 8 x 8

A = 82.67 square centimeter.

Therefore, the area of a sector of the circle if the angle at the center is 150° is 82.67 square centimeter.

Answer:

y=5(x-1)^2-1

Step-by-step explanation:

Answer:

5(x - 1)² - 1

Step-by-step explanation:

Given

5x² - 10x + 4

Using the method of completing the square

The coefficient of the x² term must be 1 , so factor out 5 from the first 2 terms

= 5(x² - 2x) + 4

add/ subtract ( half the coefficient of the x- term )² to x² - 2x

= 5(x² + 2(- 1)x + 1 - 1 ) + 4

= 5(x - 1)² - 5 + 4

= 5(x - 1)² - 1 ← in vertex form

The LCM of 12 and 10 is 60 so you would need to buy 60 / 12 = 5 packs of eggs and 60 / 10 = 6 packs of muffins.

Answer:

Step-by-step explanation:

From the expression xy = 4, y = 4/x

Substituting y = 4/x into the expression  y(x-4)(x+2) and expanding;

=  y(x-4)(x+2)

= 4/x(x-4)(x+2)

On expansion;

= (4-16/x)(x+2)

= 4x+4(2)-(16/x)x-(16/x)2

= 4x+8-16-32/x

= 4x-8-32/x

The equivalent expression is 4x - 8 - 32/x

Answer:

180

Step-by-step explanation:

Given the ratio = 7 : 3 : 2 = 7x : 3x : 2x ( x is a multiplier ), then

7x = 2x + 75 ( Natasha gets 75 more sweets than Henry )

Subtract 2x from both sides

5x = 75 ( divide both sides by 5 )

x = 15

Thus

total number of sweets = 7x + 3x + 2x = 12x = 12 × 15 = 180

3/4

Step-by-step explanation:

We can use the slope of the line by using the slope formula

m = (y2-y1)/(x2-x1)

   = (7-1)/ ( 9-1)

    = 6/8

    = 3/4

Answer: 3/4

Step-by-step explanation: To find the slope of this line, I will be showing you the graphing method.

To find the slope of the line using the graphing method,

we first set up a coordinate system.

Next, we plot our two points, (1, 1), which we label point A, and (9, 7), which we label point B, and we graph our line, as shown below.

Now, remember that the slope, or m, is equal to

the rise over run from point A to point B.

To get from point A to point B, we rise

6 units and run 8 units to the left.

So our slope, or rise over run, is 6 over 8, which reduces to 3/4.

Answer:

17.32m ; 110°

Step-by-step explanation:

Distance between X and Z

To calculate the distance between X and Z

y^2 = x^2 + z^2 - (2xz)*cosY

x = 20, Z = 10

y^2 = 20^2 + 10^2 - (2*20*10)* cos60°

y^2 = 400 + 100 - (400)* 0.5

y^2 = 500 - 200

y^2 = 300

y = sqrt(300)

y = 17.32m

Bearing of Z from X:

Using cosine rule :

Cos X = (y^2 + z^2 - x^2) / 2yz

Cos X = (300 + 100 - 400) / (2 * 20 '*10)

Cos X = 0 / 400

Cos X = 0

X = cos^-1 (0)

X = 90°

Bearing of Z from X

= 20° + X

= 20° + 90°

= 110°
