Answer: Perimeter = 22*sqrt(2)

Area = 60.5 inches

Step-by-step explanation:

Simple a square has 4 equal sides.

It contains (by definition) 1 right angle but since we are not including and statement about parallel sides, it needs 4 right angles.

Answer:

4* $\sqrt{60.5}$ is peremiter and 60.5 is area

Step-by-step explanation:

11x11=121/2=60.5

$\sqrt{60.5}$ =one side of square

4* $\sqrt{60.5}$ =peremiter

60.5=area

For the function y=-1+6cos(2pi/7(x-5)) what is the minimum value?

s344n2d4d5 [400]

Answer:

The minimum value of y is -7

Step-by-step explanation:

Given: $y=-1+6\cos(\dfrac{2\pi}{7}(x-5))$

We are given a cosine function.

We need to find minimum value of function.

$y=-1+6\cos(\dfrac{2\pi}{7}(x-5))$

Here y is depends on cosine function.

y is minimum when cosine is minimum because y is directly proportional to cosine function.

Minimum value of cos x is -1

Therefore, For minium value of y

$\cos(\dfrac{2\pi}{7}(x-5))=-1$

Minimum value of y

$y=-1+6(-1)$

$y=-7$

Hence, The minimum value of y is -7

a cat measures 76 cm from its nose to its tail the length of a lion is 3 times as long as a car how long is a lion? Give your an

xenn [34]

Answer:

ok so if the lion is 3 times bigger we have to multiply the length of the cat by

3*76=228

so the lion is 228 cm long

now we divide by 100 for meters

228 divided by 100=2.28 meters

Hope This Helps!!!

3. Use the given information about the polynomial graph to write out the equation.

scZoUnD [109]

Answer:

$f(x)=-\frac{1}{12}(x-3)^2(x+2)^2(x-4)$

Step-by-step explanation:

The standard form for a polynomial equation in its factored form is:

$f(x)=a(x-p)(x-q)...$

Where p and q are the zeros and a is the leading coefficient.

We know that the degree of the polynomial is 5.

We are also given roots at x=3 and x=-2. Hence, our factors are (x-3) and (x+2).

These have a multiplicity of two, so we will square them.

We also know that there is a root at x=4. Hence, the factor is (x-4). This has a multiplicity of 1.

Therefore, our polynomial is now:

$f(x)=a(x-3)^2(x+2)^2(x-4)$

We know that the y-intercept is 12. Therefore, if we substitute in 0 for x, we should get 12 for y. Here, we are solving for our a. Therefore:

$12=a(0-3)^2(0+2)^2(0-4)$

Evaluate:

$12=a(9)(4)(-4)$

Evaluate:

$-144a=12$

Divide both sides by -144:

$a=-1/12$

Hence, our entire polynomial is:

$f(x)=-\frac{1}{12}(x-3)^2(x+2)^2(x-4)$

Renting video games from Store S costs $2.50 per game plus a monthly fee of $5.00. Renting video games from Store T costs $5.00

tigry1 [53]

Answer: A. 2.5v+5v < 5v

Step-by-step explanation:

represents the piece of information which states that renting videos is $2.50 per game and the 2.5 is multiplied by the number of games v. Five is added as a monthly fee therefore the left side of the equation should be 2.5v+5.

For store T:

There is no monthly fee and so the renting fee of $5 per game is represented as 5v.

In conclusion, if the inequality sign in the middle is less than (<) then the left hand side of the inequality sign should represent store S and the right hand side should represent store T in order to answer the question. This makes option A the only correct option.
