Which table represents the function y = 2x + 4?

Answer:

50

Step-by-step explanation:

Angle 95 and ( 2x - 5 ) are alternate interior angles.

Alternate interior angles are equal.

2x - 5 = 95

2x = 95 + 5

2x = 100

x = 100 / 2

x = 50

Given:

A right triangle with angles 30, 60, 90 degrees.

Hypotenuse = [tex]2\sqrt{2}[/tex] mm.

Base = y

To find:

The value of y.

Solution:

In a right angle triangle,

[tex]\cos \theta = \dfrac{Base}{Hypotenuse}[/tex]

[tex]\cos (60^\circ)= \dfrac{y}{2\sqrt{2}}[/tex]

[tex]\dfrac{1}{2}=\dfrac{y}{2\sqrt{2}}[/tex]

[tex]\dfrac{2\sqrt{2}}{2}=y[/tex]

[tex]\sqrt{2}=y[/tex]

Therefore, the value of y is [tex]\sqrt{2}[/tex] mm.

Answer:

To solve this problem, you need to use the distributive property, which states that for any two numbers a and b, and for any numbers x and y, (a + b) * x = ax + bx and x * (a + b) = xa + xb.

Applying the distributive property, we have:

(-5i)(7 + i) = (-5i) * 7 + (-5i) * i

= -35i + (-5i) * i

Now, you need to use the fact that i * i = -1:

(-5i)(7 + i) = -35i + (-5i) * i

= -35i + (-5) * (-1)

= -35i - 5

= -40i - 5

So the final result is -40i - 5.

On solving the equation n = za the value of a is obtained as a = n/z.

What is an equation?

A mathematical definition of an equation is a claim that two expressions are equal when they are joined by the equals sign ("=").

To solve for a in the equation n = za, isolate a on one side of the equation.

Do this by dividing both sides by z:

n/z = (za) / z

On the right side, the z's cancel out, leaving -

n/z = a

So the solution is -

a = n/z

Therefore, the value of a that satisfies the equation n = za is equal to n divided by z.

Answer:

20

Step-by-step explanation:

The line measures a total of 180°

So make an equation where all of the angles added together = 180

100 + 3x + x = 180

Then solve for x.

First, combine like terms.

100 + 4x = 180

Subtract 100 from both sides

4x = 80

Divide both sides by 4 to isolate x

x = 20

The two consecutive odd numbers such that the difference between their reciprocals is of 2/99 are given as follows:

9 and 11.

The two numbers are odd numbers and consecutive, hence they are symbolized as follows:

n and n + 2. (as n + 1 is even).

Their reciprocals are given as follows:

The difference of their reciprocals is obtained as follows:

1/n - 1/(n + 2) = 2/99.

The least common factor of n and n + 2 is of n x (n + 2), hence:

(n + 2 - n)/[n(n + 2)] = 2/99

2/[n(n + 2)] = 2/99.

As the numerators are equal, we take the denominators to solve for n as follows:

n(n + 2) = 99.

n² + 2n - 99 = 0.

(n - 9)(n + 11) = 0.

Applying the Factor Theorem, the solutions are given as follows:

We want the positive numbers, hence the numbers are:

n = 9 and n + 2 = 9 + 2 = 11.

Answer:

Shop B

Step-by-step explanation:

First, find the number of scarves that Shop A sold: 15% of 120 scarves is 15/100 * 120 scarves = 18 scarves.

Then, find the number of scarves that Shop B sold: an eighth of 152 scarves is 152/8 = 152/8 = 19 scarves.

Since 18 scarves is less than 19 scarves, Shop B sold more scarves.

The value of the angle theta is 58 degrees

From the question, we have the following parameters that can be used in our computation:

Sin 0=0.85

Express the angle in the equation properly

So, we have the following representation

sin(Ф) = 0.85

Take the arc sin of both sides of the equation

So, we have the following representation

sin⁻¹(sin(Ф)) = sin⁻¹(0.85)

Evaluate the arc sin of one side of the equation

So, we have the following representation

Ф = sin⁻¹(0.85)

Evaluate the arc sin of the other side of the equation

So, we have the following representation

Ф = 58.2116693829

Approximate the equation

Ф = 58 degrees

Hence, the solution is 58 degrees

From the question, we have the following parameters that can be used in our computation:

Velocity function v(t) = −t2 + 5t − 3

Express properly

So, we have

v(t) = -t² + 5t − 3

At time t = 3 seconds, we have

v(3) = -(3)² + 5(3) − 3

Evaluate

v(3) = 3

So, we have

Acceleration = v(3)/3

Answer:

Step-by-step explanation:

Total Weight of cable = 800 pounds

Length of cable = 200 feets

Weight per foot = Total weight / length = 800 / 200 = 4 pounds per foot

Weight of piece will be :

Weight of cable - weight per foot * x

800 - 4x

Workdone with 300 pound load attached :

∫f(x)

f(x) = (800+300 - 4x) = 1100 - 4x

∫1100 - 4xdx at 200 to 0

Integrating the above

1100x - 4/2x² at x = 200 to 0

1100x - 2x²

The length of UV in the circle is given as follows:

13.2.

We are given two secant segments in the circle for this problem.

For two secants, the product of the lengths of one secant segment and it's external segment equals the product of the lengths of the other secant segment and it's external segment.

Hence, from the circle given by the image presented at the end of the answer, the relation for this problem is given as follows:

(22 + 17) x 17 = (20 + UV) x 20

Hence we must simply solve the expression to obtain the length of UV, as follows:

39 x 17 = 400 + 20UV

663 = 400 + 20 UV

20 UV = 263

UV = 263/20

UV = 13.2.

Step-by-step explanation:

Let the unit distance be 'x'.

There are 4 units in between A and E. It means,

A(unit) + 4(unit) = E(unit)

-1 (1/2) + 4x = (1/2)

-(2+1)/2 + 4x = 1/2
