Answer:

40 square units

Step-by-step explanation:

The surface area is given by

LA = 2(wh+lh)

where h is the height l is the length and w is the width

We do not include the top or bottom

We know l=6 w=4 and h=2

LA = 2 ( 4*2 + 6*2)

lA = 2( 8+12)

    = 2 (20)

    = 40

Answer:

log₄ 10 = log₁₀ 10 / log₁₀ 4

Step-by-step explanation:

Taking the x to be a power then;

[tex]4^x +2 =12[/tex]

[tex]4^x = 12-2[/tex]

[tex]4^x=10[/tex]

Introduce log on both sides

x log 4= log 10

x= log 10/log 4

log₄ 10 = log₁₀ 10 / log₁₀ 4

Answer: x = log₄(3/4)  = -0.207

Step-by-step explanation:

when you have the equation:

n^x = b

whe have that:

Logₙ(b) = x

in this case we have the equation:

4^(x+2) = 12

(4^x)*(4^2) = 12

16*4^x = 12

4^x = 12/16 = 3/4

x = log₄(3/4)  = -0.207

Final answer:

To find the coordinates of point C when given the midpoint M and point D, we find the average of the endpoints' coordinates. Solving the equations, we find that the coordinates of point C are (2, 8).

Explanation:

The student is asking to find the coordinates of point C given that the midpoint M of line segment CD is at (6, 6), and point D is at (10, 4). To find point C, we use the concept that the midpoint's coordinates are the average of the coordinates of the endpoints of the segment. That means:

The x-coordinate of C can be found by the equation 6 = (xC + 10) / 2 which leads to xC = 2(6) - 10,

The y-coordinate of C can be found by the equation 6 = (yC + 4) / 2 which leads to yC = 2(6) - 4.

Solving for xC and yC, we find:

xC = 12 - 10 = 2,

yC = 12 - 4 = 8.

Therefore, the coordinates of point C are (2, 8).

Answer:

So ordered pair a is (2,11)

Step-by-step explanation:

We are given

a = b+c

and ordered pair b =(6,3) and ordered pair c =(-4,8)

Putting values of b and c in the given equation and adding x and y coordinates of b and c we can find ordered pair a.

a=(6,3)+(-4,8)

a =(6-4,3+8)

a =(2,11)

So ordered pair a is (2,11)

Answer:

Julie=35 lbs, Ted= 70 lbs, and Mike=105 lbs

Step-by-step explanation:

Julie=x ted=2x mike=3x

The sum of their weight all together is 210 pounds

Combine the x's

6x=210

Divide both sides by 6 to get 1x (Julies weight)

6x/6 = 210/6

1x= 35 (Julie weighs 35 lbs)

35 x 2= 70 ( Ted weighs 70 lbs)

35 x 3= 105 ( Mike weighs 105 lbs)

Answer:

B

Step-by-step explanation:

Circumference of a circle is:

C = 2πr

Area of a circle is:

A = πr²

The circumference of the well is 47 ft and the area of the well in the drawing is 0.641 cm².  If we say r is the radius of the circle on the drawing in centimeters and R is the actual radius of the well in feet, then:

47 = 2πR

0.641 = πr²

Solving for each:

R = 47 / (2π) ≈ 7.48 feet

r = √(0.641 / π) ≈ 0.452 cm

The scale is the ratio of R / r:

R / r = (7.48 ft) / (0.452 cm) = 16.6 ft/cm

So 1 cm = 16.6 ft.

This isn't one of the options.  Are you sure you copied the problem correctly?

Maybe you meant that the circumference is 4π feet, and the area is 0.64π cm².  If so:

R = 4π / (2π) = 2 feet

r = √(0.64π / π) = 0.8 cm

R / r = (2 feet) / (0.8 cm) = 2.5 ft/cm

So 1 cm = 2.5 ft.

Check the picture below, that enclosed area is pretty much our "washer".

now, to get the outer radius, or "farther" radius from the axis of rotation, what I usually do is, use the f(x) - g(x) to get the area under the curve, using the axis of rotation for g(x).

[tex]\bf \stackrel{\textit{top, f(x)}}{4\sqrt{x}}~~-~~\stackrel{\textit{bottom, g(x)}}{(0)}\implies \stackrel{\textit{farthest radius}}{4\sqrt{x}-0\implies 4\sqrt{x}} \\\\\\ \stackrel{\textit{top, f(x)}}{x}~~-~~\stackrel{\textit{bottom, g(x)}}{(0)}\implies \stackrel{\textit{closest radius}}{x-0\implies x} \\\\[-0.35em] ~\dotfill\\\\ 4\sqrt{x}=x\implies \stackrel{\textit{squaring both sides}}{16x=x^2\implies }16x-x^2=0[/tex]

[tex]\bf x(16-x)=0\implies x= \begin{cases} 0\\ 16 \end{cases}\qquad \qquad \impliedby \textit{these are the bounds} \\\\[-0.35em] ~\dotfill\\\\ \displaystyle\int\limits_{0}^{16}~\pi [(4\sqrt{x})^2-(x)^2]dx\implies \pi \int\limits_{0}^{16}[16x-x^2]dx\implies \pi \int\limits_{0}^{16}16x~~-~~\pi \int\limits_{0}^{16}x^2[/tex]

[tex]\bf \pi \left. 16\cdot \cfrac{x^2}{2} \right]_{0}^{16}-\left. \cfrac{\pi x^3}{3} \right]_{0}^{16}\implies \left. \pi 8x^2 \cfrac{}{}\right]_{0}^{16}-\left. \cfrac{\pi x^3}{3} \right]_{0}^{16} \\\\\\ \left( \pi [2048]-\pi [0] \right)-\left(\left[ \cfrac{4096\pi }{3} \right]-[0] \right)\implies 2048\pi -\cfrac{4096\pi }{3} \implies \cfrac{2048\pi }{3}[/tex]

Answer:

99x +84 ≤ 1,150

Step-by-step explanation:

Her budget is $1,150, this means that the price of all her purchases cannot exceed it. In other words, the sum of all her purchases must be less or equal to 1,150.

To find how many watches she can buy, you need to multiply it by the price of the watches, which is $99, so it will be 99x.

As for the shirts, she spent $84.

So the inequality equation you will need will be the sum of the price of watches and shirts is less than or equal to 1,150.

99x + 84 ≤ 1,150

We don't get to see the figure but we don't need it.

The remaining angle B is

B = 180 - 27 - 78 = 75°

The Law of Sines gives the remaining sides

[tex]a = \dfrac{b \sin A}{\sin B} = \dfrac{66 \sin 27}{sin 75} \approx 31.0203[/tex]

[tex]c = \dfrac{b \sin C}{\sin B} = \dfrac{66 \sin 78}{sin 75} \approx 66.8350[/tex]

Answer: B=75°, a=31.0, c=66.8

No need for "or" on this one.  That happens when we know the sine of an angle so there are two possibilities for the angle, an acute one and an obtuse one that's supplementary.

Answer:

He needs 0.075 lbs of sugar and 4.925 lbs of water.

Step-by-step explanation:

Let x lbs be the amount of sugar in the syrup. Then 5-x lbs is the amount of water in this syrup.

Note

5 lbs - 100%

x lbs - 1.5%

Write a proportion:

[tex]\dfrac{5}{x}=\dfrac{100}{1.5}[/tex]

Cross multiply:

[tex]100x=5\cdot 1.5\\ \\100x=7.5\\ \\x=\dfrac{7.5}{100}=0.075[/tex]

So, he needs 0.075 lbs of sugar and 5 - 0.075 = 4.925 lbs of water.

Answer:

Step-by-step explanation:

And arithmetic sequence is a sequence in which the difference between each of the numbers are constant.

It is not A, because the difference between 3 and 9 is positive 6, and the difference between 9 and 81 is positive 72.

It is not C, because the difference between 4 and 1 is -3, and the difference between 1 and 4 is positive 3.

It is not D, because the difference between 2 and -2 is -4, and the difference between -2 and 2 is positive 4.

And it is B because the numbers maintain a constant difference between each other, which is -3.

Answer:

B

Step-by-step explanation:

An arithmetic sequence has a common difference (d) between consecutive terms.

The only sequence with a common difference is B

1 = 4 = - 3

- 2 - 1 = - 3

- 5 - (- 2) = - 5 + 2 = - 3

For this case we must find an expression equivalent to:

[tex](2 \frac {1} {2} * 2 \frac {3} {2}) ^ 2[/tex]

So, we have:

[tex]2 \frac {1} {2} = \frac {2 * 2 + 1} {2} = \frac {5} {2}\\2 \frac {3} {2} = \frac {2 * 2 + 3} {2} = \frac {7} {2}[/tex]

Rewriting the expression:

[tex](\frac {5} {2} * \frac {7} {2}) ^ 2 =\\(\frac {35} {4}) ^ 2 =\\\frac {35} {4} * \frac {35} {4} =\\\frac {1225} {16} =\\76 \frac {9} {16}[/tex]

(pm) 5sqrt(6)/2

(pm) 6.12372           (rounded version)

Step-by-step explanation:

F=mv^2/r  (Given)

rF=mv^2    (Multiply both sides by r)

rF/m=v^2   (Divide both sides by m)

v=(pm) sqrt(rF/m)  (Square root both sides)-(pm means plus or minus)

v=(pm) sqrt(rF)/sqrt(m)  

v=(pm) sqrt(rF)sqrt(m)/m   (I had multiply top and bottom by sqrt(m))

v=(pm) sqrt(rFm)/m

*sqrt( ) means square root of whatever is in the (  ) that follows the sqrt

Now find v if F=50, m=100 kg, and r=150/2=75 so plug in

v=(pm) sqrt(75*50*100)/100

v=(pm) sqrt(375000)/100  OR

v=(pm) sqrt(100*25*3*25*2)/100

v=(pm) 10*5*sqrt(3)*5*sqrt(2)/100

v=(pm) 250sqrt(6)/100

v=(pm) 2.5sqrt(6)

v=(pm) 5sqrt(6)/2

Or if you want a decimal number rounded, it would be (pm) 6.12372

The formula for calculating the centripetal force of an object in circular motion can be rearranged to find velocity. You compute the tangential velocity of a 100kg object with a force of 50N, moving on a circular path with a diameter of 150m, by plugging these values into this rearranged formula. This calculation results in a value of approximately 61.24 m/s for the tangential velocity of the object.

The formula F=mv^2/r calculates the centripetal force (F) of an object of mass (m) moving in a circular path with a radius (r). You can solve this formula for velocity (v) by first multiplying both sides by r, making the formula Fr=mv^2. Then, divide both sides by m, which makes the formula Fr/m = v^2. Finally, take the square root of both sides to get v = √(Fr/m).

To calculate the tangential velocity of a 100kg object with a force of 50 Newton, moving along a circular path with a diameter of 150 meters, you must first divide the diameter of the circle by 2 to get the radius, 75 meters. Next, substitute the given values into the formula; v = √((50N * 75m) / 100kg). Therefore, the tangential velocity is approximately √(3750N·m/kg) = 61.24 m/s.
