Tyler finds an expression for V(x) that gives the volume of an open-top box in cubic inches in terms of the length x in inches of the square cutouts used to make it. This is the graph Tyler gets if he allows x to take on any value between -1 and 7.

What is the approximate maximum volume for his box?

Sheesh good luck

Step-by-step explanation:

.........

Answer:

3

Step-by-step explanation:

MN is not equal to NR, because MN is too long

It doesn't tell us R is the midpoint of MN, so for all we know MR and RN are completely different measurements.

PR and QR must be equivalent if R is the midpoint of the two.

Answer:

k =15 and please give brainliest

Step-by-step explanation:

Answer:

15) m∠A = 21°, m∠B = 125°, m∠C = 34°

16) m∠J = 48°, m∠K = 57°, m∠L = 75°

Explanation:

15) m∠A is thirteen less than m∠C, so if you were to translate that into numerical terms, it would be (x-13). m∠B is eleven less than four times m∠C, so that would be (4x-11). Because the angles of a triangle sum up to 180°, the equation for this scenario would be (x-13)+(4x-11)+x=180. (X is a variable for m∠C. Add all the like terms to get 6x-24=180. Add 24 to both sides to get 6x=204. Divide 6 on both sides to get x=34. Now that we know m∠C, we can substitute 34 into x to get m∠A as 21° and m∠B as 125°.

16) m∠K is 9 more than m∠J, which is (x+9). m∠L is 21 less than twice m∠J, which is (2x-21). Again, a triangle's angles sum up to 180°, so the equation would be (x+9)+(2x-21)+x=180. Add the like terms to get 4x+(-12)=180. Add 12 to both sides to get 4x=192. Divide 4 on both sides to get x=48. Substitute 48 for x to get m∠K = 57° and m∠L=75°.

Which best describe the base area of the pan

The base area (B) is calculated using:

[tex]B = \pi r^2[/tex]

Where

[tex]r = \frac{1}{2}D[/tex]

So, we have:

[tex]r = \frac{1}{2}*7[/tex]

[tex]r = \frac{7}{2}[/tex]

[tex]r = 3\frac{1}{2}[/tex]

Substitute [tex]r = 3\frac{1}{2}[/tex] in [tex]B = \pi r^2[/tex]

[tex]B = \pi (3\frac{1}{2})^2[/tex]

Answer:

$1200

Step-by-step explanation:

Let the roof be square shaped

Area of the roof = L²

L is the side length of the roof

Given

L = 40ft

Area of the roof = 40²

Area of the roof = 1600ft²

If plants used for a green roof cost $0.75 per square foot, this means

1 ft² = $0.75

Let the cost needed to cover both sides of the roof be y, hence;

1600ft² = y

Divide both expressions

1/1600 = 0.75/y

y × 1 = 0.75×1600.

y = 0.75×1600

y = 1200

Hence it will cost $1200 to cover both sides of the roof

Answer:

The answer is x  =  13.32182916

Step-by-step explanation:

Isolate the variable by dividing each side by factors that don't contain the variable.

Multiply  30.5  by  15.2 .

463.6  ⋅  x  =  6176

Divide each term by  463.6  and simplify.

Hoped this helped!

Brainly, please?

Answer:

13.32

Step-by-step explanation:

30.5 times 15.2 is 463.6

So now the equation is 463.6x=6176

divide both sides by 463.6

x= 13.32

Answer:

145cm is the area I believe.

Answer:

Only the first point lies on the line and thus, Anders is incorrect

Step-by-step explanation:

Here, we want to show that Anders is incorrect

we simply substitute the values of his coordinates into the equation of the line

for (10,420)

we have;

420 = 40(10) + 20

420 = 420

This is right

We now test the second given point;

-420 = 40(-10) + 20

-420 = -400 + 20

-420 is not -380

Answer: The value of the bond when Tyler's mom purchased it = $150

Step-by-step explanation:

Let x= Purchasing price of the bond.

Given: Rate of increase in its value = 4% = 0.04

Value of bond after one year = x+ 4% of x

= x+0.04x

= 1.04x

One year after it was purchased, the value of the savings bond was $156.

[tex]\Rightarrow\ 1.04x = 156\\\\\Rightarrow\ x=\dfrac{156}{1.04}\\\\\Rightarrow\ x=150[/tex]

Hence, the value of the bond when Tyler's mom purchased it = $150
