Answer:

100

Step-by-step explanation:

10^2 is 100 therefore it is 100

The future value of the annuity after the end of 5 years is $552.56.

Given that, r =5%= 0.05, 5 years  = 5 yearly payments, so n = 5, and P = $100.

The formula to find the annuity formula [tex]FV=\frac{P \times ((1+r)^{n}-1 )}{r}[/tex].

Now, [tex]FV=\frac{100 \times ((1+0.05)^{5}-1 )}{0.05}[/tex]

⇒FV = 100 × 55.256

⇒FV = $552.56

Therefore, the future value of the annuity after the end of 5 years is $552.56.

Answer: Graph B is a valid density curve because the curve is above the horizontal axis, and the area under the curve is 1.

The last statement "Graph B is a valid density curve because the curve is above the horizontal axis, and the area under the curve is 1." is the correct statement.

A few fundamental principles apply to density curves:

Following the rules above, we can see from graph B that the curve is above the horizontal axis. That shows that the probabilities are positive which is a necessity. Moreover, the area under the curve must also be 1. That is also satisfied.

Hence, the last statement "Graph B is a valid density curve because the curve is above the horizontal axis, and the area under the curve is 1." is the correct statement.

An equation is formed of two equal expressions. The sum of all possible values of x is 16.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

3x + 2y = 21

3x = 21 - 2y

x = (21-2y)/3

Since the value of x is needed to be positive, the value of 2y must not exceed 21. Also, the value of (21-2y) must be a multiple of two.

Now, the values of y that will satisfy the given condition in the equation are 0, 3, 6, and 9.

Further, the sum of the possible values of x are,

Sum = 7 + 5 + 3 + 1 = 16

Hence, the sum of all possible values of x is 16.

Answer:

E.  16y

Step-by-step explanation:

Given equation:

5(x - 6y) = 50y

Expand the brackets using
Distributive Property for subtraction:  a(b - c) = ab - ac

⇒ 5 · x - 5 · 6y = 50y

⇒ 5x - 30y = 50y

Add 30y to both sides:

⇒ 5x - 30y + 30y = 50y + 30y

⇒ 5x = 80y

Divide both sides by 5:

⇒ 5x ÷ 5 = 80y ÷ 5

⇒ x = 16y

Answer:

  $7800

Step-by-step explanation:

The total interest earned can be found by summing the earnings from each of the investments.

Let x represent the total amount invested. Then Jessica's earnings are ...

  (x/2)(0.07) +(x/2)(0.13) = 780

Simplifying the equation gives ...

  (x/2)(0.07 +0.13) = 780

  0.10x = 780

  x = 7800 . . . . . . . . divide by 0.10

Jessica has $7800 invested.

There are 8,709,120 ways to arrange the people around the table

The given parameters are:

People = 13

Actors = 9

If the actors must seat together, then the actors must be grouped as 1.

The 9 actors can be arranged in 9! ways

Now, we have 1 group + 4 individuals.

This equals 5 people (in theory)

The 5 people can be arranged in 5! ways

So, the number of ways is

Ways= 9! * 5!

Evaluate

Ways = 8,709,120

All the options are incorrect. the required average is (3x-9)/2.

Thermometer A reads xº.
Thermometer B reads 2° below the reading on thermometer A = x-2
Thermometers C and D each read 4° less than twice the reading on thermometer  = 2(x-2)-4

Average of the values is the ratio of total sum of values to the number of values.

As per question,
A=x
B = x-2
C.D = 2(x-2)-4= 2x-8
Average = A + B + C + D /4

Answer:

x-intercepts:  (-1, 0) and (2, 0)

x-intercept:  (-3, 0)

Step-by-step explanation:

Given quadratic function:

[tex]f(x)=-4x^2+4x+8[/tex]

The x-intercepts of a quadratic function are the points at which the curve crosses the x-axis ⇒ when y = 0

Therefore, to find the x-intercepts of the given function, set the function to zero:

[tex]\implies -4x^2+4x+8=0[/tex]

Factor out -4:

[tex]\implies -4(x^2-x-2)=0[/tex]

Divide both sides by -4

[tex]\implies x^2-x-2=0[/tex]

Rewrite the middle term as -2x + x:

[tex]\implies x^2-2x+x-2=0[/tex]

Factor the first two terms and the last two terms separately:

[tex]\implies x(x-2)+1(x-2)=0[/tex]

Factor out the common term (x - 2):

[tex]\implies (x+1)(x-2)=0[/tex]

Zero Product Property:  If a ⋅ b = 0 then either a = 0 or b = 0 (or both).

Using the Zero Product Property, set each factor equal to zero and solve for x (if possible):

[tex]\begin{aligned}(x+1) & = 0 & \quad \textsf{ or } \quad \quad (x-2) & = 0\\\implies x & = -1 & \implies x & = 2\end{aligned}[/tex]

Therefore, the x-intercepts are (-1, 0) and (2, 0).

---------------------------------------------------------------------------------------

Given quadratic equation:

[tex]-9 = x^2 + 6x[/tex]

Add 9 to both sides:

[tex]\implies x^2+6x+9=0[/tex]

Rewrite the middle term as 3x + 3x:

[tex]\implies x^2+3x+3x+9[/tex]

Factor the first two terms and the last two terms separately:

[tex]\implies x(x+3)+3(x+3)=0[/tex]

Factor out the common term (x + 3):

[tex]\implies (x+3)(x+3)=0[/tex]

[tex]\implies (x+3)^2=0[/tex]

Square root both sides:

[tex]\implies (x+3)=0[/tex]

Solve for x:

[tex]\implies x=-3[/tex]

Therefore, the x-intercept is (-3, 0).

As the function has a repeated factor (multiplicity of two), the curve will touch the x-axis at (-3, 0) and bounce off.
