Answer:

3y^2 - (y + 2) (y - 2) = 0

<=> 3y^2 - (y^2 - 4) = 0

<=> 2y^2 + 4 =0

<=>y^2 + 2 = 0

=> Because y^2 is always equal or larger than 0, there is no real solution.

Hope this helps!

Answer:

k=3.5

Step-by-step explanation:

1. Understand which lines are similar in the triangles. In this case, because we can see that the line YX is a hypotenuse and line QP is a hypotenuse we can see that YX and QP are similar. Therefore, we can see that YZ is similar to QR and ZX is similar to RP.

2. For finding an unknown side for similar triangles, you use the equation [tex]\frac{x}{y} =\frac{a}{b\\}[/tex] where x(also known as k) is the unknown side (QR), y is the similar side to the unknown(YZ), a is a known side(Let's use RP), and b is the similar side to the known side (In this cause, it would be ZX).

2. Plugging all the sides into the equation, it should turn into [tex]\frac{x}{10.5} =\frac{5.5}{16.5}[/tex].

3.After cross-multiply, you should get 16.5x=10.5×5.5 or 16.5x=57.75.

4. Then by dividing 16.5 on both sides, you should get 3.5

Answer:

D

Step-by-step explanation:

To find volume, you have to multiply all the given sides. Therefore, 14 x 5 x 6 = 2,100. (5 x 6=30 x 14=2100)

Answer:

Andre's height:  y < x < 164

Step-by-step explanation:

We will first of all convert each of the statements to mathematical inequalities, before we combine them.

Let Andre's height be = x

Lin's height be = y

The maths teacher's height = 164

Andre is a little taller than Lin:

x > y

Andre is shorter than their maths teacher, who is 164 centimetres

x<164

Combining the two inequalities, we have Andre's height as

y < x < 164

This means that Lin is shorter than Andre who is in turn shorter than the Maths Teacher.

Answer:

Measure of the smallest angle = 35 degrees.

Step-by-step explanation:

As it is a right triangle the values of the 2 smaller angles will add up to 90 degrees.

So  the 2 angles can be written as x and 90-x and  we have:

(90 - x) - x = 20

-2x = 20 - 90 = -70

x = 35.

So the 2 angles are 35 and 55 degrees.

In a right triangle measure of the smallest angle is equals to [tex]35[/tex] degrees.

" Angle is defined as when two rays meet at one point ."

According to the question,

In a right triangle,

[tex]'\theta'[/tex] represents the measure of smallest angle

[tex]'90- \theta'[/tex] represents the measure of largest angle.

As per given condition of angle we have,

[tex]90- \theta- \theta = 20\\\\\implies 2\theta = 90 + 20\\\\\implies \theta = \frac{70}{2}\\ \\\implies \theta = 35 degrees[/tex]

Hence, in a right triangle measure of the smallest angle is equals to [tex]35[/tex] degrees.

Answer:

The amount of money he should invest in a 1-year deposit is  $3,333.333

The amount of money he should invest in a 2-year deposit is $4,333.333

The amount of money he should invest in a 3-year deposit is $8666.67

Step-by-step explanation:

The given parameters are;

Total investment = $12,000

Total interest = $600

Interest rate = r

Amount invested in a 2-year deposit, B = $1,000 + Amount invested in a 1-year deposit, A

Amount invested in a 3-year deposit, C = $12,000 - (A + B)

C = 12000 - 2·B + 1000 = 13000 - 2·B

∴ A + B + C = $12,000

A×r + 2×r×B + 3×r×C = $600

∴ r×(A + 2·B + 3·C) = $600

r×(12000 + B + 2·C) = $600

B = A + 1000

∴ r×(B - 1000 + 2·B + 3·(13000 - 2·B) = $600

r×(B - 1000 + 2·B + 3·(13000 - 2·B) = $600

r×(38000 - 3·B) = $600

∴B + 2·C = -3·B

4·B = 2·C

C = 2·B

Hence;

B - 1000 + B + 2·B = $12,000

3·B = 13,000

∴ B = 13000/3 = [tex]\$4,333\tfrac{1}{3}[/tex] = $4,333.333

B = A + 1000

∴ A = B - 1000 = [tex]\$3,333\tfrac{1}{3}[/tex] = $3,333.33

C = 2×B = [tex]\$8,666\tfrac{2}{3}[/tex] = $8666.67

Therefore;

The amount of money he should invest in a 1-year deposit =  $3,333.333

The amount of money he should invest in a 2-year deposit = $4,333.333

The amount of money he should invest in a 3-year deposit = $8666.67.

The only even prime number is 2, so the digit in the lakhs place is 2. We have 2 options for the tens thousands and tens places, 3 and 1 or 5 and 3 respectively. 7 and 5 does not work because 7 + 5 = 12, and 12 is not a digit.

Answer:

(5,-1) and choice A

Step-by-step explanation:

The first step is to figure out where the two vectors are. Since one goes to (2,-3) and the other goes to (3,2), you already know that the only possible correct answer choices could be A and B, since C and D go to the wrong coordinates. Since the two vectors are originating from the same point and are not build on top of each other, you solve this by averaging them instead of adding head to tail. Using the pythagorean theorem, you know that the length of the new vector will be [tex]\sqrt{(3^2+2^2)+(3^2+2^2)}=\sqrt{26}[/tex]. The side lengths have length 5 and 1, since [tex]5^2+1^2=26[/tex]. Therefore, the coordinates of the new vector are (5,-1). Hope this helps!

Answer: 326.73 is the precise answer

The requried curved surface area of the cylinder is approximately 35.927 square centimeters.

To find the curved surface area of a cylinder, we use the formula: C = 2πrh, where C is the circumference, π is a mathematical constant approximately equal to 3.14159, r is the radius of the base, and h is the height of the cylinder.

In this case, we are given the circumference C = 4 cm and the height h = 9 cm.

To find the radius, we can use the formula: C = 2πr. Rearranging the formula to solve for r:

r = C / (2π)

Substituting the given values:

r = 4 cm / (2 * 3.14159)

r ≈ 0.6366 cm

Now that we have the radius, we can calculate the curved surface area using the formula:

Curved surface area = 2πrh

Substituting the values:

Curved surface area = 2 * 3.14159 * 0.6366 cm * 9 cm

Curved surface area ≈ 35.927 cm²

Therefore, the curved surface area of the cylinder is approximately 35.9 square centimeters.

32 pi square meters (sorry if it is wrong)

The area base of the cylinder is 32π square meters which is correct option(A).

The volume of a cylinder is equal to the product of area of circular base and height of a cylinder. The volume of a cylinder is defined as the space occupied by the cylinder as the volume of any three-dimensional shape is the space occupied by it

V = A × h, where

A = area of the base

h = height

The base of a  circular cylinder is a circle and the area of a circle of radius 'r' is πr². Thus, the volume (V) of a circular cylinder, using the formula, is, V = πr²h

where , 'r' is the radius of the base (circle) of the cylinder

'h' is the height of the cylinder

π is a constant whose value is either 22/7 (or) 3.142.

Given data,

The volume of cylinder = 288π cubic meters

V = πr²h

Substitute the value of V in the formula

288π = π(r²)(9)

Divided by π both the sides,

288 = 9 r²

288/9 = r²

32 = r²

r² = 32

r ≈ 5.65 meters

The area base (circle) of the cylinder = πr²

Substitute the value of r in the formula,

The area base  of the cylinder = π(5.65)²

The area base  of the cylinder = π(32)

The area base of the cylinder = 32π

Hence, the area base of the cylinder is 32π square meters.
