What is the area of this composite figure?

Mathematics
1 answer:
Gelneren [198K]2 years ago
5 0

Answer:

249 centimeters squared

Step-by-step Explanation:

The area of the rectangle: l x w, where l is the length and w is the width.

= 15.5 x 18

= 279

Area of the smaller rectangle: l x w, where l is the length and w is the width.

= 4 x 7.5

= 30

We do not need this 30.

Area of the shaded region:

= 279 - 30

= 249 cm²

Which function produces an output of 5 for an input of -6?
kodGreya [7K]

Answer:

The answer is D

Step-by-step explanation:

Since the input is -6, you input it into the equation. That would make it f(-6)=-(-6)-1 which would be equivalent to f(-6)=6-1 , as the negatives at the beginning of the equation cancel each other out and make it positive. Then you solve and get 5, which is your output. Hope I could help :)

PLEASE HELP I DONT UNDERSTAND I HAVE A FEW MIN TO SUBMIT
Lunna [17]

Answer:

Increasing: (\infty, -1) \cup (2, \infty)

Decreasing: (-1, 2)

Step-by-step explanation:

So when an equation has and odd degree, it will go in the opposite direction on both ends, so if y went towards infinity as x went towards infinity, then y would go towards negative infinity as x goes towards negative infinity. In this case, by looking at the graph it has an odd degree, due to opposite end behaviors, although on both ends it's increasing because even though it appears that it's going down on the left side, that's only if you start from the right and go towards the left. So it's really increasing from negative infinity to -1, and then it decreases from -1 to 2, until it once again starts increasing from 2 to infinity. This can be represented as (-infinity, -1) U (2, infinity) for increasing and (-1, 2) as decreasing

Thanks and a metal to who ever answers:) Cuban military invaded Eastern Mexico in a surprise attack. Cuba intends to gain territ
Aleksandr-060686 [28]
The United Nations has historically been the place to ask for aid and sometimes for mediation when one nation attacks another - as in Korea in 1950 or Kuwait in 1990. 

Most nations in North and South America are members of the Organization of American States the OAS, which is, among other things, a mutual defense treaty to support one another in the event of attack. 

I assume from your question that in this exercise you are imagining yourself to be the US President or his advisors. 

Responses in a case like this would be military, using naval and air forces to support Mexican military operations, perhaps including transport of US troops to Mexico to assist. Also, bombing strategic military stations in Cuba would weaken the Cuban military's ability to support its invasion.
