Answer:

<h2>1a. 10, 15, 21, 28, 36</h2><h2>1b. Graph attached below</h2><h2>1c. Not linear</h2><h2>1d. 14, 15, 16, 17, 18, 19, 20, 21</h2><h2>1e. Graph attached below (second image)</h2><h2>1f. Description below</h2>

Step-by-step explanation:

1a. To solve for the missing digits, we need to look for a pattern. In other words, we need to deduce what is done to x to achieve y. We add the previous result of the addition to the x to get y.

1 = 1

2 + 1 = 3

3 + 3 = 6

4 + 6 = 10

5 + 10 = 15

6 + 15 = 21

7 + 21 = 28

8 + 28 = 36

1b. Graph attached below

Ordered pairs (2,3)  (3,6)  (4,10)  (5,15)  (6,21)  (7,28)  (8,36)

1c. Not linear.

The graph shown is not linear because we can clearly see that it is not a straight line.

1d. Just like with the previous problem, we need to determine a pattern.

0 + 10 = 10

1 + (1 + 2) + 10 = 14

2 + (1 + 2) + 10 = 15

3 + 13 = 16

4 + 13 = 17

5+ 13 = 18

6 + 13 = 19

7 + 13 = 20

8 + 13 = 21

1e. Graph attached below (second image)

Ordered pairs (0,10)  (1,14)  (2,15)  (3,16)  (4,17)  (5,18)  (6,19)  (7,20)  (8,21)

1f. The graph starts a 10, then jumps to 14 then counts up by 1 each time. The medalists graph counts up unsteadily the whole time.

I'm always happy to help :)

If a cone with a diameter of 10 m has a surface area of 190.6m2, find its slant height. Round to the nearest tenth.
alukav5142 [94]

Answer:  The slant height of the cone is 65.6 m

Step-by-step explanation:

Given: The diameter of a cone = 10 m

Surface area of cone = 190.6 m²

To find: Slant height

Diameter of cone = 10 m

Therefore Radius of cone = \dfrac{\text {Diameter }}{2} = \dfrac{10}{2} =5m

As we know that surface area of a cone is given by

S.A. = \pi r(l+r)

Where S.A. is surface area , r is the radius of cone and l is the slant height of the cone.

Let Slant height = l

So we have

190.6 = \dfrac{22}{7} \times 5 ( 5+l)\\\\\Rightarrow  5+l= \dfrac{190.6 \times 7}{22}\\\\\Rightarrow l=  \dfrac{1334.2}{22}+5\approx 60.64+5 = 65.64\approx65.6

Hence the slant height of the cone is 65.6 m

Si f(x) es igual a raiz de x al cuadrado menos 16 determinar f(5),f(4),f(6),f(3)
Nadusha1986 [10]

Aplicando la función, los valores numéricos son :

f(5) = -11

f(4) = -12

f(6) = -10

f(3) = -13

La función es dada por:

f(x) = (\sqrt{x})^2 - 16  = x - 16

Para los valores numéricos, reemplazamos x, luego:

f(5) = 5 - 16 = -11

f(4) = 4 - 16 = -12

f(6) = 6 - 16 = -10

f(3) = 3 - 16 = -13

Brenda walk the dogs after school she is planning to increase the rate that she charges by 20% in January when does current rate
Agata [3.3K]

Answer:

$5.40

Step-by-step explanation:

To find the increase we need to consider our variables.

Current Rate = $4.50

Increase Percentage = 20% or 0.20

Now we can find the new rate by multiplying the Current Rate to the Increase Percentage and add it to the Current Rate again.

Total Price w/ Increase = ($4.50 x 0.20) + $4.50

Total Price w/ Increase = $0.90 + $4.50

Total Price w/ Increase = $5.40

I don't know how to do any of this
Lady bird [3.3K]

Answer:

Remember that when a variable is times with a number, you will <u>divide</u> it by that number which is times with variable on both sides.

when a variable is divided by the number, you will <u>multiply</u> it by that number on the both sides.

I hope you understand my explanation. Thank you !!
