Maslowich

Answer:

(1) For x = –12, g (x) = -9

For x = –9, g (x) = -3

For x = –6, g (x) = 3

For x = –3, g (x) = 9

(2) The principal amount of money is $80.

Step-by-step explanation:

(1)

The expression of g (x) is,

$g(x)=2x+15$

The complete table is:

x g (x)

-15 $2(-15)+15=-15$

-12 $2(-12)+15=-9$

-9 $2(-9)+15=-3$

-6 $2(-6)+15=3$

-3 $2(-3)+15=9$

0 $2(0)+15=15$

(2)

The formula for simple interest is:

$I=P\times r\times t$

Given:

I = $40

r = 10%

t = 5 years.

Compute the value of P as follows:

$I=P\times r\times t$

$P=\frac{I}{r\times t}$

$=\frac{40}{0.10\times 5}\\\\=80$

Thus, the principal amount of money is $80.

PLS HELP ASAP I WILL IVE BRAINLIST ANSWER!!!!!Leon verified that the side lengths 21, 28, 35 form a Pythagorean triple using thi

Juliette [100K]

Answer:

Leon is correct. (Option 1)

Step-by-step explanation:

Given that Leon verified that the side lengths 21, 28, 35 form a Pythagorean triple using this procedure.

Step 1: Find the greatest common factor of the given lengths: 7

Step 2: Divide the given lengths by the greatest common factor: 3, 4, 5

Step 3: Verify that the lengths found in step 2 form a Pythagorean triple.

we have to explain whether or not Leon is correct.

As, 3,4,5 forms a Pythagorean triplet i.e satisfies the Pythagoras theorem

$Hypotenuse^2=Base^2+Perpendicular^2$

⇒ $5^2=3^2+4^2$

Let a, b, c forms a Pythagorean triplet

$a^2+b^2=c^2$

Multiplied by 4 on both sides

⇒ $4a^2+4b^2=4c^2$

⇒ ${2a}^2+{2b}^2={2c}^2$

Hence, we say 4a, 4b and 4c also forms a Pythagorean triplet.

∴ multiplying every length of a Pythagorean triple by the same whole number results in a Pythagorean triple.

Hence, Leon is correct.

Compare partial products and regrouping how the methods are alike and different

shtirl [24]

Partial products are different in regrouping in terms of how numbers are clustered from a set equation as a whole delivering it individual but naturally to all the numbers involved in the set. 
Regrouping is just like the commutative or associative property of numbers.
Associative property of addition is used when you want to group addends. This is mainly used to cluster set of numbers or in this case, addends. How do you use the associative property when you break apart addends? Simple you group them using the open and closed parentheses or brackets. Take for an example 1 + 1 + 2 = 4. Using the associative property you can have either (1 + 1) + 2 = 4 or 1 + (1 + 2) = 4 clustered into place.

A species of horned beetle has a (starting) population size of 4000 individuals. Every month, 170 individuals are born. However,

erma4kov [3.2K]

Answer:

Kindly check explanation

Step-by-step explanation:

Given the following :

Starting population = 4000

Addition per month = 170

decline on population per month = 70

Increase rate in population per month (dt) :

Starting population = 4000

Number of births per month = 170

However, the population declines by 70 individuals each month

Hence,

Number of births - number of deaths(d) = 70

170 - d = - 70 ( decline?

170 + 70 = d

240 = d

d = number of deaths

Per capita death :

Total number of deaths per. Month / starting population

= 240 / 4000

= 0.06
