Please help!! Solve x^2 = 36 for x. I think it may be A not so sure tho.

Answer:

x = 25

Step-by-step explanation:

the angle in a semicircle is 90°

given the legs of the triangle are congruent then the triangle is isosceles with the 2 base angles congruent.

the sum of the 3 angles in the triangle = 180°

base angle = (180 - 90)° ÷ 2 = 90° ÷ 2 = 45° , then

2x - 5 = 45 ( add 5 to both sides )

2x = 50 ( divide both sides by 2 )

x = 25

Answer:

140 pennies

Step-by-step explanation:

Information:

Define the variables:

If the piggy bank contains 350 pennies and nickels:

[tex]\implies x+y=350[/tex]

If the piggy bank contains pennies and nickels worth $11.90:

[tex]\implies 0.01x+0.05y=11.90[/tex]

Rearrange the first equation to make y the subject:

[tex]\implies y=350-x[/tex]

Substitute the expression for y into the second equation and solve for x:

[tex]\implies 0.01x+0.05(350-x)=11.90[/tex]

[tex]\implies 0.01x+17.5-0.05x=11.90[/tex]

[tex]\implies -0.04x=-5.6[/tex]

[tex]\implies x=140[/tex]

Therefore, there are 140 pennies in the piggy bank.

Answer:

A = 267 calories; B = 257 calories

Step-by-step explanation:

We can set up a system of equations to find how many calories each candy bar provides.

The information gives us:

A + 2B = 781 and 2A + B = 791.

Substitution will be easier, and we can isolate A from the first equation and then plug it in for A in the second equation:

[tex]A+2B=781\\2A+B=791\\\\A=781-2B\\\\2(781-2B)+B=791\\1562-4B+B=791\\1562-3B=791\\-3B=-771\\B=257[/tex]

Now we can plug in B into the first equation to find A:

[tex]A+2(257)=781\\A+514=781\\A=267[/tex]

W =∫ lower power (-r) to higher power (r + h) (h + r - x) 2pgl [tex]\sqrt{r^2+x^2}[/tex] dx is the integral for the effort needed to pump water out of a spout that is 2 m above the tank.

Integral: In mathematics, an integral is either a number representing the region under a function's graph for a certain interval or a new function, the derivative of which is the original function (indefinite integral).

r = 2m

l= 5m

sinθ=x/r

[tex]dv=2l\sqrt{r^2+x^2} dx[/tex]

Let g be the acceleration brought on by gravity, and let p be the density of water.

dm = p dv

dw = dmg (h + r - x)

dw = pg (h + r - x) dx

dw = 2lpg  (h + r - x) [tex]\sqrt{r^2+x^2}[/tex] dx

w = ∫dw

w = ∫ lower power (-r) to upper power (r + h) 2pgl (h + r - x)  [tex]\sqrt{r^2+x^2}[/tex] dx

Therefore, the integral for the work required to pump the water out of a

spout that rises 2 m above the tank is

w = ∫ lower power (-r) to upper power (r + h) 2pgl (h + r - x) [tex]\sqrt{r^2+x^2}[/tex] dx

The statement that the mean attendance is higher than 523 does not have enough facts to stand up.

What is null hypothesis?

A null hypothesis is an educated guess or a prediction of the expected outcome of a particular experiment. It is a statement that assumes there is no difference between two groups or no association between two variables. The null hypothesis is often the opposite of the alternative hypothesis, which is the prediction that the researcher is hoping to prove.

Example 1: In a study of the effectiveness of a new drug for treating depression, the null hypothesis would be that the drug has no effect on depression levels.

Example 2: In a study of the association between smoking and lung cancer, the null hypothesis would be that there is no association between the two variables.

In the given question, there are a total of 64 students in a film-making club and a yearbook club.

The film-making club has 14 more students than the yearbook club.

a. We have to write a system of linear equations that represents this situation.

Let x represent the number of students in the film-making club

Let y represent the number of students in the yearbook club.

As given that the film-making club has 14 more students than the yearbook club.

So x = y+14

Total students are 64.

So x+y = 64

System of equations:

x= y+14

x+y = 64

b. Now we have to find how many students are in the film-making club and the yearbook club.

The system of equations are;

x= y+14...................(1)

x+y = 64...................(2)

Now putting the value of x in equation 2.

y+14+y = 64

2y+14 = 64

Subtract 14 on both side, we get;

2y = 50

Divide by 2 on both side, we get;

y = 25

According to the question,

The perimeter of the window is 16 feet

Also, Window is surmounted by an equilateral triangle

Let x and y be the dimensions of rectangular part of window and x be side of equilateral part. If A be the total area of window, then

A = x.y + (√3/4)x² -------------(1)

Also, x + 2y + 2x = 16

=> 3x + 2y= 16

=> y = 16-3x / 2

Replacing the value of y in equation (1)

=> A = x.(16-3x / 2) + (√3/4)x²

=> A = 8x - 3x²/2 +  (√3/4)x²

Differentiating A w.r.t x

=> A' = 8 - 3x +  (√3/2)x

For critical value , we put A'=0

=> 8 - 3x +  (√3/2)x = 0

=> x = 16 / ( 8 - √3)

Again, Differentiating A' w.r.t x ,

=> A'' = -3 + √3/2

which is Less than 0 ,

Therefore , A is maximum if x = 16 / ( 8 - √3) and y = 24 - 8√3 /  8 - √3
