Answer:

option d

13 , 173 , 29933

Step-by-step explanation:

Given in the question a function, f(x) = x² + 4

initial value x0 = -3

First iteration

f(x0) = f(-3) = (-3)² + 4 = 13

x1 = 13

Second iteration

f(x1) = f(13) = (13)² + 4 = 173

x2 = 173

Third iteration

f(x2) = f(173) = (173)² + 4 = 29933

x3 = 29933

Step-by-step explanation:

Coordinate of A = (-3, 9)

Coordinate of B = (-1, 6)

[tex]\text {Distance = }\sqrt{(- 3 - (-1) )^2 + (9 - 6)^2}[/tex]

[tex]\text {Distance = }\sqrt{(- 2 )^2 + (3)^2}[/tex]

Calculate the distance using the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = A(- 3,9) and (x₂, y₂ ) = B(- 1, 6)

d = [tex]\sqrt{-1+3)^2+(6-9)^2}[/tex]

[tex]-\dfrac{1}{2}(6x-5)\qquad\text{use the distributive property}\ a(b+c)=ab+ac\\\\=\left(-\dfrac{1}{2}\right)(6x)+\left(-\dfrac{1}{2}\right)(-5)=-3x+2.5[/tex]

Final answer:

The expression equivalent to -1/2 (6x-5) is -3x + 2.5. The distributive property is used to multiply -1/2 with each term inside the parentheses.

Explanation:

The expression equivalent to -1/2 (6x-5) can be found by applying the distributive property of multiplication over addition and subtraction. This property allows us to multiply each term inside the parentheses by -1/2 to achieve the equivalent expression. Therefore, we proceed as follows:

Multiply 6x by -1/2 to get -3x.

Multiply -5 by -1/2 to get 5/2 or 2.5.

Putting it all together, the equivalent expression is -3x + 2.5. When simplifying expressions involving negative exponents or distributing negative factors, it's essential to carefully apply the multiplication to each term separately to avoid errors.

If the output of the function is 5, then the input is

1. 8. ( optionC)

2. 9 ( Option D)

3. 0( option A)

4. The equation for the situation is y = x -5 ( option D).

It expresses a unique output for each input, exemplified by f(x) in algebraic terms.

In the equation;

y = x -3

the output is y

therefore;

5 = x -3

x = 5+3 = 8

Therefore the input value is 8.

2. The input value will be

x = y × 2

x = 4.5 ×2 = 9

3. The input value will be

x = 6 - 6

= 0

4. let y be the cost after the coupon and x is before the coupon

y = x - 5

The most efficient way to solve this problem is isolating the y in the first equation because:

6x + 3y = 27

3y = 27 - 6x

y = 9 - 2x

Since all the numbers have a common factor of 3, it can be easily simplified/reduce.

If you used any other variable, you would have gotten a fraction.

Now that you found y, you can substitute it into the other equation to solve for x.  

ANYWAYS, your answer is A

Answer:

Final answer:

To rewrite the logarithm log(xy), you apply the property that the logarithm of a product is equal to the sum of the logarithms of the individual factors, resulting in log x + log y.

Explanation:

The logarithm you are asked to rewrite is log(xy). According to the properties of logarithms, the logarithm of a product is equal to the sum of the logarithms of the individual factors. This means that log(xy) = log x + log y. This rule is useful for simplifying logarithmic expressions and is a direct consequence of how exponents work.

Another property to remember is that the logarithm of a number raised to an exponent is the product of the exponent and the logarithm of the number. This is expressed as log(xy) = y × log x.

Remember, both properties are fundamental in working with logarithms and can be applied regardless of the base of the logarithm, whether it's log to the base 10, ln for natural logarithms (to the base e), or any other base.

Final answer:

The initial velocity at which she threw the cap is 20 m/s.

Explanation:

Since the cap comes back to her hand at the same height, the initial vertical velocity of the cap is 0 m/s. The acceleration due to gravity is -10 m/s². Using the equation v = u + at, where v is the final velocity, u is the initial velocity, a is the acceleration, and t is the time, we can solve for the initial velocity. In this case, v = 0 m/s, a = -10 m/s², and t = 2.0 s. Plugging in these values, we get:

0 = u + (-10)(2.0)

0 = u - 20

u = 20 m/s

So the initial velocity at which she threw the cap is 20 m/s.

Answer:

6=1/2z

6÷1/2=1/2÷1/2z

z=12

For this case we must find the value of "x" of the following equation:

[tex]x ^ 2-9 = 0[/tex]

So:

We add 9 to both sides of the equation:

[tex]x ^ 2-9 + 9 = 9\\x ^ 2 = 9[/tex]

We apply square root on both sides of the equation to eliminate the exponent on the left side:

[tex]x = \pm \sqrt {9}[/tex]

Thus, the solutions are:

I'm confirming the answer above. These are also the answers on Edge-nuity. I use Edge-nuity

Step-by-step explanation:

A local maximum occurs over the interval  (-2,0)  

A local minimum occurs over the interval  (0,2)

We may calculate the maximum of a continuous and twice differentiable function f(x) by first differentiating it with respect to x and then equating it to 0.

A local maximum occurs over the interval (-2,0)  

A local minimum occurs over the interval  (0,2)

Hence, local maximum and local minimum occurs at  (-2,0)  and (0,2).

Answer:

The measure of  angle x is 90°

Step-by-step explanation:

Given the figure in which

∠1=88°, ∠6=89°

we have to find the value of x.

∠5=∠6=89°   (∵ Vertically opposite angles)

∠1+∠4=∠6  ( ∵ By exterior angle property)

88°+∠4=89°

∠4=89°-88°=1°

As AC=CB (both are radii of same circle)

∴ ∠4=∠3=1°

Now, by exterior angle property

x=∠5+∠3=89°+1°=90°

Hence, the measure of  angle x is 90°

Applying the angle of intersecting chords theorem, the value of x in the diagram showing the circle is: C. 90.

According to the angle of intersecting chords theorem, the measure of the angle formed at the point of intersection of two chords inside a circle equals half the sum of the intercepted arcs.

89 = 1/2(88 + x) [based on the angle of intersecting chords theorem]

2(89) = 88 + x

178 = 88 + x

178 - 88 = x

x = 90° (Option C).

Ginven the expression:

[tex]2sin(x)*cos(x)*sec(x)*csc (x)[/tex]

You need to substitute [tex]sec(x)=\frac{1}{cos(x)}[/tex] and [tex]csc(x)=\frac{1}{sin(x)}[/tex] into it:

The volume of a rectangular prism is length * width * height.

Substitute in the values to get 8 * 5 * height = 80.

Now, simplify to get 40 * height = 80.

Divide both sides of the equation by 40 to get height = 2.

This means the height of the rectangular prism is 2 inches.

A rectangular prism is a 3-dimensional shape; height, width, length. These three variables, when multiplied, will produce a volume for a rectangular prism. We are given everything we need but the height.

Given:

Volume, V = 80 in3

Length, L = 8in

Width, W = 5in.

Height, H = H in

8 inches * 5 inches * H inches = 80 inches3

40 inches2 * H inches = 80 inches 3

(divide each side by 40 inches2)

H inches = 2 inches.

Step-by-step explanation:

took test

The linear velocity at the end of the blade is 13571.7 inches per minute by using the circumference of the circle that the blade makes to calculate the linear velocity at the end of the blade.

The circle is a closed two dimensional figure , in which the set of all points is equidistance from the center.

Here, The total distance in 1 minute is 60 times circumference of the circle made by the end of the blade of the lawnmower.

Since, The blade is 36 inches long, it can be taken as radius of that circle.

The circumference is thus calculated as;

⇒ linear velocity = 226.19 × 60

                           = 13571.7 inches per minute

Thus, The linear velocity at the end of the blade is 13571.7 inches per minute.

Step-by-step explanation:

To convert degrees to radians

radian measure = degree measure × [tex]\frac{\pi }{180}[/tex]

Hence

radian measure = 150° × [tex]\frac{\pi }{180}[/tex]

Cancel both 150 and 180 by 30, then

radian measure = 5 × [tex]\frac{\pi }{6}[/tex] = [tex]\frac{5\pi }{6}[/tex]

Final answer:

To convert 150 degrees to radians, multiply 150 by π/180 to get 5/6 * π or approximately 2.61799 radians.

Explanation:

To convert 150 degrees to radians, we use the fact that one complete revolution is 360 degrees which is equal to 2π radians (approximately 6.28318 radians). From this, we can derive that 1 degree is equal to π/180 radians. We multiply the value in degrees by π/180 to get the equivalent in radians.

150 degrees * π/180 radians/degree = 150/180 * π radians = 5/6 * π radians.

Therefore, 150 degrees is equal to 5/6 times π or approximately 2.61799 radians.
