Answer:

Volume of sphere A = 128x (Approx.)

Step-by-step explanation:

Given:

Radius of sphere A = 2 x Radius of sphere B

Volume of sphere B = 16x

Find:

Volume of sphere A

Computation:

Volume of sphere = (4/3)(π)(r)³

Volume of sphere B = (4/3)(π)(r)³

16x = (4/3)(π)(r)³

16x = (4/3)(22/7)(r)³

16x = (88/21)(r)³

Radius of sphere B = 1.56∛x Approx.

Radius of sphere A = 2 x Radius of sphere B

Radius of sphere A = 2 x 1.56∛x

Radius of sphere A = 3.12∛x Approx.

Volume of sphere A = (4/3)(π)(r)³

Volume of sphere A = (4/3)(22/7)(3.12∛x)³

Volume of sphere A = (88/21)(30.37∛x)

Volume of sphere A = 127.27x

Volume of sphere A = 128x (Approx.)

Answer:

3220 cm²

Step-by-step explanation:

Lets find the area of the two triangles

I am making a modification:

Both of the triangles are the same, so I wont divide by 2 using the area of triangle formula 1/2(b * h) because we end up multiply by 2

Area of triangles = 15 cm x 28 cm = 420 cm²

Area of front facing parallelogram = 24 cm x 4(10)cm = 100(10)cm = 1000 cm²

Area of back facing parallelogram = 17 cm x 40 cm = 680 cm²

Area of bottom parallelogram = 40 cm x 28 cm = 1120 cm²

Total Surface area = 420 cm² + 1000 cm² + 680 cm² + 1120 cm² = 1100 cm² + 2120 cm² = 3220 cm²

Given:

In triangle ABC, AE is the angle bisector.

[tex]AB=4, BE=2, AC=x, CE=3[/tex]

To find:

The value of x.

Solution:

According to the angle bisector theorem, the angle bisector of a triangle divides the opposite side of the triangle into two parts. These two parts are proportional to the other two sides of the triangle.

Using the angle bisector theorem, we get

[tex]\dfrac{AB}{AC}=\dfrac{BE}{CE}[/tex]

[tex]\dfrac{4}{x}=\dfrac{2}{3}[/tex]

On cross multiplication, we get

[tex]4\times 3=2\times x[/tex]

[tex]12=2x[/tex]

Divide both sides by 2.

[tex]\dfrac{12}{2}=x[/tex]

[tex]6=x[/tex]

Therefore, the value of x is 6.

Answer:

Since it is 0 years after 1985, the y intercept means that the population was 122,000 in 1985.

Step-by-step explanation:

Answer:

Lets say there's a quadratic equation → ax² + bx = -c

Lets make one side zero which gives → ax² + bx + c = 0

From the above equation ,

For example :- x² - 12x = -35.

Lets make one side zero → x² - 12x + 35 = 0 . Now, lets break -12x into two real numbers 'p' & 'q' such that p + q = -12x & pq = 35. Prime factors of 35 are 1 , 5 & 7. If we take 5 & 7 as 'p' & 'q' then p + q = 5 + 7 = 12. but as we need -12 , the values of 'p' & 'q' are -5 & -7.

⇒ [tex]x^2 -5x - 7x + 35 = 0[/tex]

⇒ [tex]x(x - 5) - 7(x - 5) = 0[/tex]

⇒ [tex](x - 5)(x - 7) = 0[/tex]

⇒ [tex]x = 5 \: or \: 7[/tex]

Lets take another example :- x² + 4x = 1.

Lets make one side zero → x² + 4x - 1 = 0 . Now , lets split +4x into into two real numbers 'p' & 'q' such that p + q = +4x & pq = -1 . Prime factors of 4 are 1 & 2 only. But there's no such combination of its primes such that their sum would be equal to 4. So, the quadratic equation can't be solved by factorisation method. Now, lets bring -1 to Right Hand Side & try solving by completing squares method.

⇒ [tex]x^2 + 2 \times x \times 2 + 2^2 = 1 + 2^2[/tex]

⇒ [tex](x + 2)^2 = 1 + 4 = 5[/tex]

⇒ [tex]x + 2 = +\sqrt{5} \: \: or \: -\sqrt{5}[/tex]

⇒ [tex]x = (\sqrt{5} - 2) \: or \: (-\sqrt{5} -2)[/tex]

Conclusion:

First try making one side zero and try to solve the equation by factorisation method. If it got factorised , then you are done and if it didn't get factorised , then solve it by completing squares method.

Answer:

I'm assuming we're asking about the difference between:

[tex]ax^2 + bx + c = 0[/tex]

and

[tex]ax^2 + bx = -c[/tex]

Let's preface this by stating the obvious: there's no actual difference. Both equations are equivalent.

Now, it has a lot to do with our goal. Sometimes our goal is to write an equation concisely (then the "no-zero" way uses less characters), and sometimes we're dealing with a quadratic function of

[tex]y = ax^2 + bx + c[/tex]

in the second case, we wouldn't write

[tex]y - c = ax^2 + bx[/tex]

because it'd be confusing. That means that when we're looking for y=0 points of a quadratic equation, the way to convey that goal is that we're looking for the point where [tex]ax^2 + bx + c = 0[/tex] - so we preserve the structure of the quadratic function.

Answer:

x= √10/2

Step-by-step explanation:

if you use trig. functions:

sin 45° = opposite side /hypothenuse = x/√5

sin 45° = √2/ 2

√2/2 = x/√5 multiply both sides by √5

x= (√2*√5)/2 = √10/2

if you use that is a 45-45-90 special triangle

the sides are x, and hypothenuse must be x√2 in this type of triangles so in our case:

x√2 = √5 divide both sides by √2

x= √5/√2 multiply by √2/√2 which =1 and help us get rid of the radical from the denominator

x= (√5*√2)/ (√2*√2) = √10/2

Answer:

The area of the shaded region is 11.606 square centimeters.

Step-by-step explanation:

The area of the shaded region is obtained by subtracting the area of the triangle from the area of the circular section. The area of the triangle ([tex]A_{t}[/tex]), in square centimeters, can be calculated by the Heron's formula:

[tex]A_{t} = \sqrt{s\cdot (s-a)\cdot (s-b)\cdot (s-c)}[/tex] (1)

[tex]s = \frac{a + b + c}{2}[/tex] (2)

Where:

[tex]a[/tex], [tex]b[/tex], [tex]c[/tex] - Lengths of the sides of the triangle, in centimeters.

[tex]s[/tex] - Semiperimeter, in centimeters.

If we know that [tex]a = 10.50\,cm[/tex] and [tex]b = c = 9.28\,cm[/tex], then the area of the triangle is:

[tex]s = \frac{10.50\,cm + 2\cdot (9.28\,cm)}{2}[/tex]

[tex]s = 14.53\,cm[/tex]

[tex]A_{t} = \sqrt{(14.53\,cm)\cdot (14.53\,cm - 10.50\,cm)\cdot (14.53\,cm - 9.28\,cm)^{2}}[/tex]

[tex]A_{t} \approx 40.174\,cm^{2}[/tex]

And the area of the circular section ([tex]A_{c}[/tex]), in square centimeters, is determined by the following formula:

[tex]A_{c} = \left(\frac{\theta\cdot \pi}{360} \right)\cdot r^{2}[/tex] (3)

Where:

[tex]r[/tex] - Radius of the circle, in centimeters.

[tex]\theta[/tex] - Internal angle, in sexagesimal degrees.

If we know that [tex]r = 9.28\,cm[/tex] and [tex]\theta = 68.9^{\circ}[/tex], then the area of the circular section is:

[tex]A_{c} = \left(\frac{68.9}{360}\right)\cdot \pi\cdot (9.28\,cm)^{2}[/tex]

[tex]A_{c} \approx 51.780\,cm^{2}[/tex]

Finally, the area of the shaded region ([tex]A[/tex]), in square centimeters, is:

[tex]A = A_{c} - A_{t}[/tex] (4)

[tex]A = 51.780\,cm^{2}- 40.174\,cm^{2}[/tex]

[tex]A = 11.606\,cm^{2}[/tex]

The area of the shaded region is 11.606 square centimeters.

Answer:

Option B

Step-by-step explanation:

Average rate of change of a function between x = a and x = b will be,

Average rate of change = [tex]\frac{f(b)-f(a)}{b-a}[/tex]

We have to calculate average rate of change of the given quadratic function between x = 0 and x = 2.

From the given graph,

f(2) = 6

f(0) = 10

Therefore, average rate of change = [tex]\frac{f(2)-f(0)}{2-0}[/tex]

                                                          = [tex]\frac{10-6}{2-0}[/tex]

                                                          = 2

Option B will be the answer.

y = 8 - 5x, y(-2) = 18, y(0) = 8, y(3) = -7

Step-by-step explanation:

y + 5x = 8

y = 8 - 5x

y(-2) = 8 - 5*(-2) = 8 + 10 = 18

y(0) = 8 - 5*(0) = 8 - 0 = 8

y(3) = 8 - 5*(3) = 8 - 15 = -7

Answer:

D. One of the jellybeans that slipped out was orange and one was black

Step-by-step explanation:

We calculate the option with the highest probability of occurrence :

Total number of jellybean = 75

n(T) =75

n(Pink) = 8

n(red) = 22

n(Orange) = 17

n(green) = 8

n(white) = 6

n(black) = 4

We assume that the jelly beans must have slipped out one after the other.

Evaluating the options :

A.)

P(pink) and P(white)

8/75 * 6/74 = 0.0086486

B.)

P(green) and P(green)

8/75 * 7/74 = 0.0100900

C.)

P(white) and P(white)

6/75 * 5/74 = 0.0054054

D.)

P(orange) and P(black)

17/75 * 4/74 = 0.0122522

From the probability values obtained, the highest is D. Hence, the most likely to have occurred is One of the jellybeans that slipped out was orange and one was black
