Answer:

Move the corners of the triangle up the axis by two blocks.

A = (-7,-3)

B = (-2,6)

C=  (6,-3)

The area of the garden be  after he doubles the length and width is 160 square feet.

Given that,

Based on the above information, the calculation is as follows:

We know that

Area = (length) (width)

Now if the area is doubled

So,

= (2) (length)  (2) (width)

= 4(length) (width)

= 4 (40)

= 160

Therefore, we can conclude that option b is correct.

Answer:

C) 14/4

Step-by-step explanation:

Multiply the amount of land per month by the number of months.

(2/4)(7) = 14/4 acres

Option C is correct, 14/4  acres of land does the business plant with trees after the 7 months

A fraction represents a part of a whole.

A business plants trees on 2/4 acre of land each month for 7 months.

We have to find the number of acres of land does the business plant with trees after the 7 months

To find this we have to multiply seven with two by four

7×2/4

14/4

Hence, 14/4  acres of land does the business plant with trees after the 7 months

Answer:

x=13.584

Step-by-step explanation:

[tex] \frac{x}{ \sin(51) } = \frac{11}{ \sin(39) } \\ [/tex]

[tex]x = 13.584[/tex]

[tex]180 - 39 - 90 = 51[/tex]

Answer:

[tex]K \approx 51.2^\circ[/tex]

[tex]K \approx 128.8^\circ[/tex]

Step-by-step explanation:

Given

[tex]k = 480[/tex]

[tex]j = 420[/tex]

[tex]\angle J = 43^\circ[/tex]

Required

Find the measure of K

The value of K ranges from: [tex]0^\circ \le K \le 180^\circ[/tex]

To do this, we apply sine rule;

[tex]\frac{j}{\sin J} = \frac{k}{\sin K}[/tex]

So, we have:

[tex]\frac{420}{\sin 43} = \frac{480}{\sin K}[/tex]

Cross multiply

[tex]\sin K * 420 = \sin 43 * 480[/tex]

Make sin K the subject

[tex]\sin K= \frac{\sin 43 * 480}{420}[/tex]

[tex]\sin K= \frac{0.6820 * 480}{420}[/tex]

[tex]\sin K= 0.7794[/tex]

Take arc sin of both sides

[tex]K = sin^{-1}(0.7794)[/tex]

[tex]K \approx 51.2^\circ[/tex]

Recall that: [tex]0^\circ \le K \le 180^\circ[/tex]

The other possible value of K is:

[tex]K \approx 180 - 51.2[/tex]

[tex]K \approx 128.8^\circ[/tex]

Answer:

Design and implement a plan that collects data.

Step-by-step explanation:

Looking at the answer choices, we can use the process of elimination:

1) Form a question that can be answered by data.

2) Design and implement a plan that collects data.

3) Analyze the data using graphical and numerical methods.

4) Interpret and compare the data.

1) The question is most likely already formed, as a survey cannot be conducted without a question or objective. Not 1.

2) A survey collects data.

3) This happens after the collection of data, or the survey. Not 3.

4) This also happens after the collection of data, or the survey. Not 4.

Answer:

  (x, y) = (5, 9)

Step-by-step explanation:

We must find the value of x before we can find the value of y. Fortunately, simply adding the arcs around the circle will give an equation for x.

  72x = 360 . . . simplify

  x = 5 . . . . . . divide by 72

The value of the external angle at J is half the difference of arcs GL and HK. That is, ...

  5y = (25x -7x)/2 = 9x = 9(5) . . . . simplify, fill in for x

  y = 9 . . . . . . divide by 5

The question is incomplete. The complete question is :

The volume of a right circular cone with radius r and height h is V = pir^2h/3. a. Approximate the change in the volume of the cone when the radius changes from r = 5.9 to r = 6.8 and the height changes from h = 4.00 to h = 3.96.

b. Approximate the change in the volume of the cone when the radius changes from r = 6.47 to r = 6.45 and the height changes from h = 10.0 to h = 9.92.

a. The approximate change in volume is dV = _______. (Type an integer or decimal rounded to two decimal places as needed.)

b. The approximate change in volume is dV = ___________ (Type an integer or decimal rounded to two decimal places as needed.)

Solution :

Given :

The volume of the right circular cone with a radius r and height h is

[tex]$V=\frac{1}{3} \pi r^2 h$[/tex]

[tex]$dV = d\left(\frac{1}{3} \pi r^2 h\right)$[/tex]

[tex]$dV = \frac{1}{3} \pi h \times d(r^2)+\frac{1}{3} \pi r^2 dh$[/tex]

[tex]$dV = \frac{2}{3} \pi r h (dr)+\frac{1}{3} \pi r^2 dh$[/tex]

a). The radius is changed from r = 5.9 to r = 6.8 and the height is changed from h = 4 to h = 3.96

So, r = 5.9  and dr = 6.8 - 5.9 = 0.9

     h = 4  and dh = 3.96 - 4 = -0.04

Now, [tex]$dV = \frac{2}{3} \pi r h (dr)+\frac{1}{3} \pi r^2 dh$[/tex]

[tex]$dV = \frac{2}{3} \pi (5.9)(4)(0.9)+\frac{1}{3} \pi (5.9)^2 (-0.04)$[/tex]

[tex]$dV=44.484951 - 1.458117$[/tex]

[tex]$dV=43.03$[/tex]

Therefore, the approximate change in volume is dV = 43.03 cubic units.

b).  The radius is changed from r = 6.47 to r = 6.45 and the height is changed from h = 10 to h = 9.92

So, r = 6.47  and dr = 6.45 - 6.47 = -0.02

     h = 10  and dh = 9.92 - 10 = -0.08

Now, [tex]$dV = \frac{2}{3} \pi r h (dr)+\frac{1}{3} \pi r^2 dh$[/tex]

[tex]$dV = \frac{2}{3} \pi (6.47)(10)(-0.02)+\frac{1}{3} \pi (6.47)^2 (-0.08)$[/tex]

[tex]$dV=-2.710147-3.506930$[/tex]

[tex]$dV= -6.22$[/tex]

Hence, the approximate change in volume is dV = -6.22 cubic units

Answer:

b = 9m is the answer.

Step-by-step explanation:

a = 12m

b = ?

c = 15m

According to the Pytagorean theorem,

a² + b² = c²

12² + b² = 15²

144 + b² = 225

b² = 225 - 144

b² = 81

b = 9

∴ The slide is 9m away from the monkey bars.

Answer:

x = 30 degrees

Step-by-step explanation:

a triangle's angles should all add up together to 180 degrees. Since a right angle is 90 degrees then you have your 60 degree angle that only leaves 30 degrees left.

Answer: A and C

Step-by-step explanation:

A is right because it’s right triangle since it has a right angle. C is also right, x=30 because we have 60 degrees and 90 degrees. 60 plus 90 is 150 and a triangle is equal to 180 degrees 180-150 is 30

Answer:

y = 3x + 5        

Step-by-step explanation:

1) First, find the slope between the pair of points. Use the slope formula [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]. Substitute the x and y values of points A and B into the formula and simplify:

[tex]m = \frac{(-10)-(5)}{(-5)-(0)} \\m = \frac{-10-5}{-5-0} \\m = \frac{-15}{-5} \\m = 3[/tex]

So, the slope is 3.

2) Now, identify the y-intercept of the line, or the point at which the line intersects the y-axis. All points on the y-axis have an x-value of 0. We're told that (0,5) is a point the line intersects, and since it has an x-value of 0, that must be the y-intercept.  

3) Using slope-intercept format, represented by the equation [tex]y = mx + b[/tex], write the equation of the line. Remember that the number in place of [tex]m[/tex], or the coefficient of the x-term, is the slope. So, substitute 3 for [tex]m[/tex]. Also, remember that [tex]b[/tex] represents the y-intercept of a line, so substitute 5 in its place, too. This gives the following answer:

[tex]y = 3x + 5[/tex]

Piso final - Piso inicial= 8

Reemplazando y despejando:

7-Piso inicial= 8

Piso inicial= 7-8

Piso inicial= -1

Por lo tanto, ha salido de la planta del sótano

Verificando:

Piso inicial +8= piso final

-1+8= Piso final

7= piso final
