The area bounded by the curve ay = x² and the lines y = a and y = 4a is [tex]\mathbf{ \dfrac{14a^2}{3} }[/tex]

How do you find the area bounded by a curve:

The area bounded by the curve can be determined by taking the integral of the curve such that: [tex]\mathbf{\int^{2a}_{a} x dy}[/tex]

From the given information:

[tex]\mathbf{\implies \int^{4a}_{a} (ay)^{1/2} \ dy}[/tex]

[tex]\implies \mathbf{ a^{1/2} \int^{4a}_{a} y^{1/2} \ dy}[/tex]

Applying power rule

[tex]\implies \mathbf{ a^{1/2} \Big[\dfrac{2}{3}y^{3/2}\Big] ^{4a}_0 }[/tex]

Taking the boundaries, we have:

[tex]\implies \mathbf{ a^{1/2}\dfrac{14}{3}a^{5/2} }[/tex]

[tex]\implies \mathbf{ \dfrac{14a^2}{3} }[/tex]

Answer:

12.31 teaspoons

Step-by-step explanation:

Calculate the area of a garden with a radius of 7 feet:

Area = [tex]\pi[/tex][tex]r^{2}[/tex]

Conversion factor (2 teaspoons/25ft^2)

Area = (3.14)(7)^2

Area = 153.9 ft^2

(153.9 ft^2)(2 teaspoons/25ft^2) = 12.31 teaspoons

The required number of cases are 11 and the number of rest units are 2.

If any number a is divided by the number b then we write a/b and find the numerical values of this fraction.

How to find divide of two numbers?

Here we have given

One case = 8 units

Also we have given 90 units

If each case can accommodate 8 units and we want to calculate the overall number of cases, we must divide the number of units (8) in each case by the total number of units (90).

As you can see, we have a total of 11 cases and a 2 unit leftover after dividing by 8.

We won't be able to fill another case with 8 units, thus the remainder will be the number of additional units.

Therefore 11 cases and rest 2 units are the answers.

This is the conclusion to the answer.

Answer:

d) 2p° and (p+15) ° are complementary angles.

2p° + p° + 15° = 90°

3p° = 90° - 15°

p° = 75°/3

p = 25°

Now, 2p° = 2×25° = 50°

(p+15)° = 25°+15° = 40°

e) x° and x°÷4 are supplementary angles.

x° + x°÷4 = 180°

4x + x = 180°×4

5x = 180°×4

x = 180°×4/5

x° = 36° × 4 = 144°

And x°÷4 = 144/4 = 36°

f) Complementary angles in the ratio 4:11

Let the angles be 4x and 11x .

4x + 11x = 90°

15x = 90°

x = 6°

Now, 4x = 4×6 = 24°

11x = 11×6 = 66°

g) Supplementary angles in the ratio 7:5.

Let the angles be 7x and 5x.

7x + 5x = 180°

12x = 180°

x = 180°/12

x = 15°

Hence, 7x = 7×15 = 105°

5x = 5×15 = 75°.

The domain and range of the given graphed function attached in the brainly link are;

Domain; -5 ≤ x < 1

Range; -4 ≤ y < 7

How to Interpret Inequality Graph?

Domain is simply defined as the set of all possible input values. This means it's the values on the x-axis in the graph. Meanwhile, the range is the set of all output values which in this case is the values on the y-axis.

Now, from the graph, we see that the line stopped at 2 points.

The bottom one is shaded which means it includes the numbers at that point.

It's coordinates are (-5, -4)

Thus, we can write the domain here as; x ≥ -5

While the range will be; y ≥ -5

For the second point above on the graph, we see the point where it is is not shaded and this means that the coordinates at that point are not included in the range or domain.

Thus, domain here is; x < 1

The range is ; y < 7

Combining domain intervals for both points, we will get;

Domain; -5 ≤ x < 1

Similarly, combining range intervals for both points, we have;

Range; -4 ≤ y < 7

Step-by-step explanation: Has integer coefficients and equal to 0.

Answer:

(- 4, 16 ) , ([tex]\frac{1}{2}[/tex], [tex]\frac{1}{4}[/tex] )

Step-by-step explanation:

y = x² → (1)

7x + 2y = 4 → (2)

substitute y = x² into (2)

7x + 2x² = 4 ( subtract 4 from both sides )

2x² + 7x - 4 = 0 ← in standard form

(x + 4)(2x - 1) = 0 ← in factored form

equate each factor to zero and solve for x

x + 4 = 0 ⇒ x = - 4

2x - 1 = 0 ⇒ 2x = 1 ⇒ x = [tex]\frac{1}{2}[/tex]

substitute these values into (1) for corresponding values of y

x = - 4 : y = (- 4)² = 16 ⇒ (- 4, 16 )

x = [tex]\frac{1}{2}[/tex] : y = ([tex]\frac{1}{2}[/tex] )² = [tex]\frac{1}{4}[/tex] ⇒ ( [tex]\frac{1}{2}[/tex] , [tex]\frac{1}{4}[/tex] )

Answer:

r = [tex]\sqrt{ \frac{V}{pi h }[/tex]

Step-by-step explanation:

V = pi r^2 h

Divide both sides by pi h

V / pi h = pi r^2 h / pi h

V / pi h = r^2

Take the square root of each side

sqrt( V / pi h) =sqrt( r^2)

sqrt( V / pi h) = r

r = [tex]\sqrt{ \frac{V}{pi h }[/tex]

What is addition?

The process of summing up the things or numbers or integrating something is termed the addition.

Given that:-

c/2 -5 = 7

Step 1: c/2 -5 +5 = 7 +5

Step 2: c/2 +0 = 12

Step 3: c/2 = 12

Step 4: 2(c/2) = 12(2)

Step 5: c = 24

The solution of the given expression will be done as:-

Step 1: addition property of equality (lets you add the same to both sides)

Step 2: integers are closed to addition

Step 3: identity property of addition (adding 0 changes nothing)

Step 4: multiplication property of equality

Step 5: closure of real numbers to multiplication; identity property of multiplication

It is hard to say what "property" you want to claim when you simplify an arithmetic expression. Above, we have used the property that the sets of integers and real numbers are closed to addition and multiplication. That is, adding or multiplying real numbers gives a real number.

In Step 5, we can rearrange 2(c/2) to c(2/2) using the commutative property of multiplication. 2/2=1, and c×1 = c. The latter is due to the identity element for multiplication: multiplying by 1 changes nothing.

Apart from the arithmetic, the other properties used are properties of equality. Those let you perform any operation on an equation, as long as you do it to both sides of the equation. The operations we have performed in this fashion are adding 5 and multiplying by 2.
