Answer:

The solution is B

Step-by-step explanation:

$x + 5 \geqslant 1 \\ x \geqslant 1 - 5 \\ x \geqslant - 4$

then:

$x - 7 < - 3 \\ x < - 3 + 7 \\ x < 4$

therefore, interval [limits] of x:

$- 4 \leqslant x < 4$

A population of 1,500 insects grows exponentially by a factor of 3 every week. Select all equations that represent or approximat

Andreas93 [3]

Answer:

FV(p)= PV*(1 + g)^t

Step-by-step explanation:

Giving the following information:

Number of insects (PV)= 1,500

Increase rate= 3 weekly

First, we need to calculate the daily growth rate:

Daily rate (g)= [3^(1/7)] - 1

Daily rate (g)= 0.16993

Now, by using the following formula, we can determine the population p in any given day t:

FV(p)= PV*(1 + g)^t

For, example after 7 days:

FV(p)= 1,500*(1.16993^7)

FV(p)= 4,500

For example, after 10 days:

FV(p)= 1,500*(1.16993^10)

FV(p)= 7,206

You and your friends have decided to camp for a night. Your friend claims the area of his tent is 408 m2. Work out the area of h

slamgirl [31]

We know that
area of the tent=length*breath
length=240 cm---convert to m---> 240/100----> 2.40 m
breath=170 cm----convert to m---> 170/100----> 1.70 m

find the area
area=2.40*1.70-----> area=4.08 m²

therefore

the answer is
the friend's statement is incorrect the area is 4.08 m²
