7.85

explanation

you multiply the two numbers together

Answer:

$7.85

Step-by-step explanation:

To solve this problem, we can use the cancelling of units.

cost = $3.14/1 lb * 2.5 lb

The pounds cancel out leaving dollars so you get cost = $3.14 * 2.5

so cost = $7.85.

The height of the cylinder is 8cm

The formula for calculating the volume of the cylinder is expressed as;

[tex]V = \pi r^2 h[/tex]

r is the radius

h is the height

Substitute the given parameters into the formula:

[tex]V = \pi r^2 h\\72 \pi = \pi \times 3^2h\\72 = 9h\\h=\frac{72}{9}\\h = 8cm[/tex]

Hence the height of the cylinder is 8cm

Answer: 1.3 seconds

Step-by-step explanation:

Given: Distance of the moon to the Earth = 384,400 km = 384400 x 1000 meters = 384400000 meters.  [1 km = 1000 m]

Speed of light =[tex]2.998 \times 10^8[/tex]  m/s = 299800000 m/s

Formula: [tex]\text{Time}=\dfrac{\text{Distance}}{\text{Speed}}[/tex]

Let t be the time taken by the light to travel from the moon to the Earth.

[tex]t=\dfrac{384400000}{299800000}\approx1.3\text{ seconds}[/tex]

Hence, it will take approximately 1.3 seconds for the light to travel from the moon to the Earth.

Answer:

(3, - 2 )

Step-by-step explanation:

Given the 2 equations

4x - 2y = 16 → (1)

y = - 5x + 13 → (2)

Substitute y = - 5x + 13 into (1)

4x - 2(- 5x + 13) = 16 ← distribute and simplify left side

4x + 10x - 26 = 16

14x - 26 = 16 ( add 26 to both sides )

14x = 42 ( divide both sides by 14 )

x = 3

Substitute x = 3 into (2) for corresponding value of y

y = - 5(3) + 13 = - 15 + 13 = - 2

solution is (3, - 2 )

Answer:

x = 7

Step-by-step explanation:

Given

5x - 1 - 2x = 20, that is

3x - 1 = 20 ( add 1 to both sides )

3x = 21 ( divide both sides by 3 )

x = 7

Step-by-step explanation:

5x-1-2x=20

3x-1=20

3x=20+1

3x=21

3x/3=21/3

x=7

Answer:

a = [tex]\frac{9}{4}[/tex] , b = - 2

Step-by-step explanation:

Given the 2 equations

9 = ab² → (1)

- 72 = a[tex]b^{5}[/tex] → (2)

Divide (2) by (1)

[tex]\frac{-72}{9}[/tex] = [tex]\frac{ab^5}{ab^2}[/tex]

- 8 = b³ ( take the cube root of both sides )

[tex]\sqrt[3]{-8}[/tex] = b , that is

b = - 2

Substitute b = - 2 into (1) and solve for a

9 = a(- 2)² = 4a ( divide both sides by 4 )

Answer:

1) The equation for the of the ball in y = a·(x - h)² + k is;

y = -16·(x - 5)² + 25

2) The height of the dock, d =  -375 feet below the water level

Step-by-step explanation:

1) The question is with regards to quadratic function representing projectile motion

The given parameters are;

The height the ball reaches 4 seconds after Sarah kicked the ball = 9 feet

The time the ball hits the water = 6 seconds after reaching the 9 feet height

The form of the quadratic equation representing the motion is given as follows;

y = a·(x - h)² + k = a·x² - 2·a·h·x + a·h² + k

Let 'x' represent the time of motion of the ball, and let 'a', represent the acceleration due to gravity, we have;

The equation for the ball, y = a·(x - h)² + k

Where;

(h, k) = The coordinates of the vertex

h = The horizontal component of the vertex coordinate = 0

Therefore, we have;

When x = 0, y = d

d = -16·(0 - h)² + k =  -16·h² + k

d = -16·h² + k  

When x = 4, y = 9 - d

9 - d = -16(4 - h)² + k = -16(4 - h)² + k

When x = 2, y = d

d = -16(2 - h)² + k

When x = 6, y = 9

9 = -16(6 - 5)² + k

When x = 8, y = d

d = -16(8 - h)² + k

-16(8 - h)² - (-16(2 - h)²) = 0

h = 5

From 9 - d = -16(4 - h)² + k = -16(4 - 4)² + k

d = 9 - k

9 = -16(6 - h)² + k

k = 9 + 16(6 - 5)² = 25

d = 9 - k = 9 - 25 = -16

Therefore, h = 5, k = 25

The equation for the of the ball in y = a·(x - h)² + k is therefore;

y = -16·(x - 5)² + 25

2) When x = 0, y = d, ∴ d = -16(0 - 5)² + 25 = -375 feet below the water

The height of the dock, d =  -375 feet below the water level

The graph of the equation y = -(3/2)x -2 is C.

Slope of a line is defined as the change in the value of y-coordinate with respect to the value of the x-coordinate. It is usually denoted by 'm'.

Slope can also be defined as the tangent of the angle that the line is making with the X-axis.

The equation of a line in slope-intercept form is y = mx + c, where m is the slope and c is the y-intercept.

For  y = -(3/2)x -2, m = -3/2 and c = -2

Here slope is negative, so the line will be directing downwards from left to right.

So we eliminate graph B.

y-intercept is the y-coordinate of the point where the line touches with the X-axis. The x-coordinate at that point will be zero.

So we got the a point on the line ( 0, -2 )

Since graph A does not pass through this point, it is also eliminated.

Now we find x-intercept which is the x-coordinate of the point where the line touches with the X-axis. The y-coordinate will be zero there.

So, 0 = -(3/2)x -2

⇒ 2 = -(3/2)x

⇒ x = -4/3

⇒ x = -1.333

So the line touches ( -1.333, 0).

Hence, graph C is the one which satisfies the equation  y = -(3/2)x -2.

By answering the above question, we may state that by equation Once more, we can observe that the two conjugates' product is an integer.

Using the equals notation (=) to indicate equivalence, a math equation links two statements. Algebraic equations prove the equality of three mathematical expressions by a mathematical assertion.

The equal sign, for example, provides a gap between the numbers 3x + 5 and 14 in the equation 3x + 5 = 14. You can use a mathematical formula to understand the connection between the two phrases that are inscribed on opposite sides of a letter. Most of the time, the symbol and the particular software match. e.g., 2x - 4 = 2 is an example.

An integer is always obtained when a radical expression is multiplied by its conjugate since the product has the form[tex]a^2 -b^2[/tex], where a and b are rational numbers. This is so that we may obtain the difference of the squares of the two terms within the radical when we multiply the two conjugates.

Consider the radical expression [tex]\sqrt3 - \sqrt2[/tex] and its conjugate,  [tex]\sqrt3 - \sqrt2[/tex] , to understand this. These two expressions can be multiplied as follows:

[tex]\sqrt{\sqrt3 - \sqrt2\\[/tex]

[tex]\sqrt{(\sqrt3 - \sqrt2) ((\sqrt(3 + \sqrt(2)))} = 3 - \sqrt(2 ) = 1$$[/tex]

As a result, we can observe that the two conjugates' product is an integer.

The radical phrase [tex]\sqrt5 - \sqrt3[/tex] and its conjugate, [tex]\sqrt5 +\sqrt3[/tex] , serve as another illustration.

[tex](\sqrt5 -\sqrt3)[/tex]

[tex](\sqrt(5) + \sqrt(3)) = \sqrt(5) \times \sqrt(5) + \sqrt(5) \times \sqrt(3) - \sqrt(3) \times \sqrt(3)[/tex]

[tex](\sqrt5 - \sqrt3)( \sqrt 5+ \sqrt3) = 5 - 3 = 2[/tex]

Once more, we can observe that the two conjugates' product is an integer.

I got answer 16.9

Step-by-step explanation:

1. Let's first look at triangle XYC. We know angle Y is 90 degrees because it has the symbol. and it is given that Angle X 45 degrees. Using the triangle interior angle theoreom, a triangle has 180 degrees so Angle C is 45 degrees. Know let find the sides, First we can deduce XY is 5 cm because of the triangle midsegment theorem XY is half of BC so since we know BC is 10  that means XY is 5.  Then applying 45-45-90 triangle rules, XY=5, YC=5 and XC=[tex]5\sqrt{2}[/tex].

2.Now let look at the triangle XBC. Let find one  missing angles. In the triangle . A  angle bisector  XC bisects XY and BC  . Using that information Angle C of XYC = Angle C of XBC. So angle C=45 degrees. Knowing looking at the main triangle ABC  Angle A=30, Angle C= 45+45=90 and Angle B=60 by interior triangle theorem. So going back to Angle X so angle x is 75 degrees due to interior triangle theorm. Also since Y=90 degrees it forms a linear pair to triangle AXY so Y=90 for AXY

Now let apply 30-60-90 triangle rules to AXY. XY =5, AY=[tex]5\sqrt{3}[/tex] and AX=10.  

Finally. Apply 30-60-90 triangle rules to ABC. AC=[tex]5\sqrt{3}[/tex] +5 BC=10 and AB should turrn out to be 16.9.

This may not be right,but good luck:)
