P = 2(L + W) Solve for L

Mathematics

1 answer:

Fofino [41]4 years ago

8 0

Answer:

Step-by-step explanation:

P = 2( L + W)

To solve for L first divide both sides by 2

That's

$\frac{P}{2} = L + W$

Move W to the other side of the equation to make L stand alone

We have the final answer as

$L = \frac{P}{2} - W \\$

Prove by mathematical induction the following statement:

Nady [450]

Answer:

In Exercises 1-15 use mathematical induction to establish the formula for n ≥ 1.

1. 1

2 + 22 + 32 + · · · + n

2 =

n(n + 1)(2n + 1)

Proof:

For n = 1, the statement reduces to 12 =

1 · 2 · 3

and is obviously true.

Assuming the statement is true for n = k:

2 + 22 + 32 + · · · + k

2 =

k(k + 1)(2k + 1)

, (1)

we will prove that the statement must be true for n = k + 1:

2 + 22 + 32 + · · · + (k + 1)2 =

(k + 1)(k + 2)(2k + 3)

. (2)

The left-hand side of (2) can be written as

2 + 22 + 32 + · · · + k

2 + (k + 1)2

In view of (1), this simplifies to:

F(t)=30(0.97)∧t = rate of change

Vedmedyk [2.9K]

Hey there, Lets solve this together.

 $F(t)=30(0.97)^t$

$A = (p+r)^t$

The variable (R) will be representing the rate as a decimal.

When you solve for (R) multiply by 100 to get the percentage. A percentage is a rate, number, or amount in each hundred.

"0.97" will be replaced by "(97/100)"

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the given equation

$Ft-((30))97/100) * t) = 0$

Rewrite the whole as a fraction using 10 as the denominator :

$ft = ft/1 = ft * 10/10$

The equation now takes the shape :
t • (10f-291) = 0

 f = 291/10 = 29.100

 t = 0

Positive = Growth

Negative = Decay

 $1 + r = .97$

 $r = -0.03$

Muhammad is paid x dollars an hour. He received a 10% raise. Which expression can Michael use to calculate his new hourly wage?

Mashcka [7]

Answer: 1.1x

Step-by-step explanation:

Muhammad is getting paid x dollars and receives a raise of 10% of those x dollars.

New hourly wage is therefore:

= x + (10% * x)

= x + 10%x

= x + 0.1x

= 1.1x
