126

Step-by-step explanation:

\(V = A * h = \frac{1}{4} * \pi * d^{2} * h = A * h = \frac{1}{4} * 3.14 * 36 * 5 = 141.3\\ \\V_{empty} = A * h = \frac{1}{4} * \pi * d^{2} * h = \frac{1}{4} * \pi * 4 * 5 = 15.7\)

\(V_{full} = V - V_{empty} = 141.3 - 15.7 = 125.6 \approx 126\)

Answer:

-3y

Step-by-step explanation:

"(4x – 2y) subtracted from (4x – 5y)"

(4x – 5y) - (4x – 2y) =

Drop the first set of parentheses since it is unnecessary.

= 4x – 5y - (4x – 2y)

Distribute the negative sign to the left of the parentheses by changing each sign inside the parentheses.

= 4x – 5y - 4x + 2y

Combine like terms.

= 4x - 4x - 5y + 2y

= 0 - 3y

= -3y

The expression -3y represents the difference when (4x – 2y) is subtracted

from (4x – 5y).

An algebraic expression is consists of variables, numbers with various mathematical operations,

The given expressions are,

4x - 2y and 4x - 5y

To find the expression, which represents the difference between, 4x - 2y and 4x - 5y.

Subtract 4x - 2y from 4x - 5y.

4x - 5y - (4x - 2y)

4x - 5y - 4x + 2y

0 - 3y

The component form of the vector is <3, -5, 6>, the magnitude of the vector is √70, then the unit vector is <0.386, -0.643, 0.643>.

The initial and terminal points to find the component form of the vector, calculated its magnitude, and then divided the component form by the magnitude to find a unit vector in the direction of v.

To find the component form of the vector, you can subtract the coordinates of the initial point from the coordinates of the terminal point. In this case, we have:

v = (4, 1, 6) - (1, 6, 0)

v = (3, -5, 6)

So the component form of the vector is v = <3, -5, 6>.

To find the magnitude of the vector, we can use the formula:

|v| = √(3² + (-5)² + 6²)

|v| = √70

Therefore, the magnitude of the vector is √70.

Finally, to find a unit vector in the direction of v, we can divide the component form of v by its magnitude:

u = v/|v|

u = <3/√70, -5/√70, 6/√70>

So the unit vector in the direction of v is u = <0.386, -0.643, 0.643>.

Answer:

Step-by-step explanation:

Cosine is a trigonometric function that is represented by adjacent divided by the hypotenuse. The side adjacent to angle A is AC and the hypotenuse is AB, so we can say cos(A) = \(\frac{AC}{AB}\). We can do the same for angle B. The side adjacent to it is BC, and the hypotenuse is again AB. So, we can say

cos(B) = \(\frac{BC}{AB}\). We are solving for \(\frac{cosA}{cosB}\), so we can substitute the value of those two and solve:

\(\frac{\frac{AC}{AB}}{\frac{BC}{AB} }\)

\(\frac{AC}{AB} * \frac{AB}{BC} = \frac{AC}{BC}\)

AC is given to be 3 and BC is also 3, so \(\frac{AC}{BC}\) is \(\frac{3}{3}\) which is just 1.

When r is less than 5 and we substitute r = 4 into the expression [3r-15], the result is -3.

The expression [3r-15] represents an algebraic expression that depends on the value of r. The condition given is that r is less than 5. To evaluate this expression, we substitute the value of r into the expression and simplify it.

Given that r is less than 5, let's substitute r = 4 into the expression:

[3(4) - 15]

= [12 - 15]

= -3

Therefore, when r is less than 5 and we substitute r = 4 into the expression [3r-15], the result is -3.

It's important to note that this answer is specific to the given condition that r is less than 5. If the condition changes or if r is greater than or equal to 5, the result of the expression may be different.

The value of a, b, and c are 1, -2, and 6 respectively.

The y-intercept of this quadratic function is 6.

The axis of symmetry of this quadratic function is 1.

The vertex of this quadratic function is (1, 5).

Mathematically, the axis of symmetry of a quadratic function can be calculated by using this mathematical expression:

Axis of symmetry, Xmax = -b/2a

Where:

a and b represents the coefficients of the first and second term in the quadratic function.

For the given quadratic function f(x) = x² - 2x + 6, we have:

Axis of symmetry, Xmax = -b/2a

Axis of symmetry, Xmax = -(-2)/2(1)

Axis of symmetry, Xmax = 2/2 = 1.

Vertex (h, k) = (1, 5).

In Mathematics, the y-intercept of any graph such as a quadratic function, generally occur at the point where the value of "x" is equal to zero (x = 0).

y-intercept = 6.

Lastly, we would create a table and then graph the quadratic function as follows;

By connecting points D, E, and the intersection point, Joanne will have successfully copied angle ABC with technology.

Angles are mathematical concepts that are used to describe the amount of rotation between two rays. Angles are measured in degrees and are usually represented by the symbol "°".

In the scenario described, Joanne is trying to copy angle ABC using technology. To do this, she needs to take the following steps:

Create circle A with center A and radius AB.

Draw rays AB and AC so that they intersect the circle at two points, B and C respectively.

Create another ray from points D and E.

Create circle D with center D that is congruent to circle A.

Now, in order to copy angle ABC, Joanne needs to find the intersection point of the new ray and circle D. This point will be the corresponding point of C in the new angle.

This point will be the corresponding point in the copied angle, and it can be found by using geometric concepts such as lines, circles, and angles.

Answer:

\(x\geq \frac{-16}{3}\)

Step-by-step explanation:

The correct option is that;

C. Leon overpaid for his purchase by $2.60 if he paid $44.64.

The vendor, who is acting as the state's agent, collects the sales tax and remits it to the state on behalf of the final customer. The use tax, on the other hand, is self-assessed and paid by the final customer.

Given that;

Purchase fuel = 12 Gallons per $2.89 per gallons (including Tax)

2 Granola Bar for $1.59 per bar

1  apple for $0.89

2 bottles of vitamin water for $1.39

The sales Tax rate is 7.5%

Required to calculate the difference amount of Actual Paid and Actual Purchase =?

Fuel = 12 x 2.89 = $34.68 (including tax)

Granola Bar = 2 x 1.59 = $3.18

Apple = 1 x 0.89 = $0.89

Vitamin Water = 2 x 1.39 = $2.78

Total Purchase excluding fuel without tax is,

= $3.18 + $0.89 + $2.78

= $6.85.

Adding sale tax on  $6.85 at the rate of 7.5% = $7.36

Hence, Total Purchase including Tax is,

$7.36 + $34.68 = $42.04

Thus, there is a clear difference that Leon paid 2.60 more than his actual purchase. He paid $ 44.64 and his actual purchase is 42.04 the difference between that is $2.60.

Hi... Do this for solve

The domain of the rational expression (6-x)/(4x+20) is all real numbers except x = -5.

To find the domain of a rational expression, we need to identify any values of x that would result in division by zero. Division by zero is undefined in mathematics
In this case, we need to set the denominator, 4x+20, equal to zero and solve for x:
4x + 20 = 0
Subtract 20 from both sides:
4x = -20
Divide both sides by 4:
x = -5
Therefore, the value x = -5 makes the denominator zero.
Now, we need to consider the values of x for which the denominator is not zero. Since the denominator is a linear expression (a polynomial of degree 1), it is defined for all real numbers except x = -5.
So, the domain of the rational expression (6-x)/(4x+20) is all real numbers except x = -5.
