The radius is 10.4 cm. And the angle is 120 which is 1/3 of the circle. 
Just use the area formula: 3.14 *r^2 to find the total area of 339.62 and then divide this by 3 to get 113.21. Then to subtract the triangle..find the area of the traingle which is 1/2 (10.4)^2 = 54.08. 113.21 - 54.08 = 59.13 which should be your answer

MakcuM [25]

Answer:

Step-by-step explanation:

Given:

function h(t) models the height of Pooja's plant (in cm) where

t is the number of days after she bought it.

Now we have to find about which number type is more appropriate for the domain of h.

That means what values can be taken by the variable "t".

As per the questions, t represents number of days not the hours so it will not be in decimal or fraction value. It can only use integer values for the number of days. like 1, 2, 3 ...,n  

Now as the time is counted after she bought the plant then number of days will be positive.  

Hence answer for the type of domain can be positive integers or you can say integers greater than or equal to 0.

Answer:

<u>D) (f o g)(x) = 10x² - 60x + 93</u>

Step-by-step explanation:

f(x) = 10x² + 3

g(x) = x - 3

⇒ (f o g)(x)

⇒ f(x - 3)

⇒ f(x - 3) = 10(x - 3)² + 3

⇒ f(x - 3) = 10(x² - 6x + 9) + 3

⇒ f(x - 3) = 10x² - 60x + 90 + 3

⇒ <u>(f o g)(x) = 10x² - 60x + 93</u>
