Answer:

D. (1,6)

Step-by-step explanation:

Vertical line segment:

A vertical line segment has fixed x coordinate.

In this question:

Vertical line segment that is 4 units long and is connected to (1,2).

The x-coordinate is x = 1.

The y-coordinate can be y = 2 - 4 = -2 or y = 2 + 4 = 6.

(1,6) is one of the options, so the correct answer is given by option D.

Answer:

Step-by-step explanation:

Let's get the equation first and then look at the circle when it has been graphed.

(x - 2)^2 + (y - 4)^2 = 7^2

(x - 2)^2 + (y - 4)^2 = 49

Answer:

1. a) the square root of 20

2. d) the square root of 52

Explanation:

we can use the formula of pythagoras' theorem, which is a² + b² = c² (with c being the hypotenuse of a right-angled triangle while a and b are its other two sides), to solve these questions.

for the first question, we can place the given values into the equation to get 4² + b² = 6², with b being the unknown here. b is thus equivalent to 6² - 4², or √20.

for the second question, we can get 4² + 6² = c², which is the unknown value in this question. it would be √52.

i hope this helps! :D

Answer:

area = 24 units squared

Step-by-step explanation:

area = 1/2 (base 1 + base 2) x height

area = 1/2 (4 + 8) x 4

area = 1/2 (12) x 4

area = 6 x 4

area = 24

Answer:

20.9 is the answer because To round 20.86 to the nearest tenth consider the hundredths’ value of 20.86, which is 6 and equal or more than 5. Therefore, the tenths value of 20.86 increases by 1 to 9. 20.86 rounded to the nearest tenth = 20.9

Answer:

7 marigolds will fit in this row

Step-by-step explanation:

Given

Length of the row for planting marigold =  2 yards

Spacing between the flowers = 1/3 yard

The first marigold is planted at 0 yard, the total number of marigold that can be planted is equal to

A  1/3  B  1/3  C  1/3  D 1/3  E  1/3 F 1/3 G

The alphabets represents the marigold flower

Hence, total 7 flowers can be planted

Answer:

12

Step-by-step explanation:

Formula for area of a triangle = length X width ÷ 2

so the equation would be (6 X 4) ÷ 2

which equals (24) ÷ 2

which is 12.

So the answer is 12

Answer:

its m=3 and m=4 that add up to 180

Step-by-step explanation:

not complementary.

Answer:

The answer must be the third one. Triangles must always add up to 180 degrees. It could possibly be the first one, but the problem does not give enough specific details.

Answer:

The rate of change of the surface area of the sphere is 0.99 cm²/s.  

Step-by-step explanation:

The surface area (A) of a sphere is given by:

[tex] A = 4\pi r^{2} [/tex]                      

If we derivate the above equation with respect to the time we have:

[tex] \frac{dA}{dt} = 4\pi (2r)\frac{dr}{dt} [/tex]

[tex] \frac{dA}{dt} = 8\pi r\frac{dr}{dt} [/tex]    (1)

Where:          

r: is the radius    

We need to find [tex]\frac{dr}{dt}[/tex] and r.

From the volume we can find the radius:

[tex] V = \frac{4}{3}\pi r^{3} = 256 \frac{\pi}{3} cm^{3} [/tex]  

[tex] r = \sqrt[3]{\frac{3V}{4\pi}} = \sqrt[3]{\frac{3*256*\frac{\pi}{3}}{4\pi}} = 4 cm [/tex]                

And by derivating the volume of the sphere with respect to the time we can calculate [tex]\frac{dr}{dt}[/tex]:  

[tex]\frac{dV}{dt} = \frac{4}{3}\pi(3r^{2})\frac{dr}{dt}[/tex]

[tex]\frac{dV}{dt} = 4\pi r^{2}\frac{dr}{dt}[/tex]          

[tex] \frac{dr}{dt} = \frac{\frac{dV}{dt}}{4\pi r^{2}} = \frac{2}{4\pi(4)^{2}} = 0.0099 cm/s [/tex]      

Now, we can calculate the rate of change of the surface area (equation 1):

[tex] \frac{dA}{dt} = 8\pi r\frac{dr}{dt} = 8\pi*4*0.0099 = 0.99 cm^{2}/s [/tex]

Therefore, the rate of change of the surface area of the sphere is 0.99 cm²/s.  

I hope it helps you!          

Answer:

7.5

Step-by-step explanation:

Answer:

1)

Null hypothesis            H₀ : μ = 25,809

Alternative hypothesis H₁ : μ < 25,809

2) Test Statistic = -1.44

3) Conclusion:

The result is significant, there is sufficient evidence to support the bride’s hope at the 0.10 level of significance.

Step-by-step explanation:

Given the data in the question;

Sample mean x" = 24,638

sample size n = 46

standard deviation σ = 5531

level of significance ∝ = 0.10

NULL and ALTERNATIVE HYPOTHESIS

Null hypothesis            H₀ : μ = 25,809

Alternative hypothesis H₁ : μ < 25,809

TEST STATISTICS

Z = (x"-μ) / σ√n

we substitute

Z = (24,638 - 25,809) / (5531/√46)

Z = -1171 / 815.5

Z = -1.44

Test Statistic = -1.44

Now, from normal z-table;

P-value = P( Z < -1.44 ) = 0.0749

P-value = 0.0749

Since P-value ( 0.0749 ) is less than level of significance ( 0.10 ), we reject H₀.

Conclusion:

The result is significant, there is sufficient evidence to support the bride’s hope at the 0.10 level of significance.

Answer:

Step-by-step explanation:

For the considered case, the weight 6 pound 1 ounce will be taken as : Option C: Lower quartile.

When we get data which can be compared relatively with each other, for finding quartiles, we arrange them in ascending or descending order.

Quartiles are then selected as 3 points such that they create four groups in the data, each groups approximately possessing 25% of the data.

Lower quartile, also called first quartile has approx 25% in its left partition, and on its right lies approx 75% of the data.

Similarly, second quartile (also called median) is approximately in mid of the data.

Third quartile (also called upper quartile)  has approx 75% in its left partition, and on its right lies approx 25% of the data.

Left to right is said in assumption that data was arranged increasingly from left to right

For this case, it is said that 25% of the class weighted less than 6 pounds 1 ounce. That means it is first quartile or say lower quartile.

Thus, for the considered case, the weight 6 pound 1 ounce will be taken as : Option C: Lower quartile.

Answer:84.7

Step-by-step explanation: you add up all the side lengths

area = 255 [tex]m^{2}[/tex]

perimeter = 20+6.7+8+8+15+26 = 83.7m

Step-by-step explanation:

top left triangle - base is 3 because (20-8-9).  so 1/2 bh = 1/2 (3) (6) = 9

left rectangle = l x w = 20 x 6 = 120

middle square = l x w = 8 x 9 = 72

lower right triangle = height is 12 because (26-8-6), so 1/2 bh =1/2 (9)(12) = 54

9+120+72+54 = 255
