You are saving for a skateboard. Your aunt gives you $45 to start, and you save $3 each week. The expression 45 + 3w gives the amount of money you save after w weeks. How much will you have after six weeks?

In this case we know that the parabola does not cross the x-axis, thus, the quadratic equation has no solutions.

For a quadratic function (also called a parabola)

y = a*x^2 + b*x + c

the solutions of the quadratic equation are the values of x such that:

a*x^2 + b*x + c = 0

Now, remember that the values with y = 0 are called the x-intercepts, then the solutions of the above equation are x-intercepts.

And here we know that the parabola does not cross the x-axis, thus, the quadratic equation has no solutions.

Answer:x=1.

Step-by-step explanation:

3x-x+2=4

The probability that a club member owns neither a house nor a car is 0.08 or 8%.

As per the survey of a club's members-

percentage of members who own a home 40% = 0.4

percentage of members who own a car → 90% = 0.9

Further, 95% of the homeowners also own a car

⇒ percentage of members who own a car as well as a home = 95% of 40%

= 95/100 x 40/100

= 3800/10000

= 0.38

Let P(A) be the probability that a member owns a home and P(B) be the probability that a member owns a car

we have,

P(A) = 0.4

P(B) = 0.9

also P(A∩B) = 0.38

we need to find the probability that a club member owns neither a house nor a car, that is, P(A'∩B')

According to the rules of probability-

P(AUB) = P(A) + P(B) - P(ANB)

⇒ P(AUB) = 0.4 +0.9 -0.38

P(AUB) = 0.92

Thus, P(A'U B') = 1 - 0.92

= 0.08

Thus, the probability that a club member owns neither a house nor a car is 0.08 or 8%.

Step-by-step explanation:

[tex]4^{3} =4^{X} \\\\The base cancels out\\3= X[/tex]

  22)

[tex]Log 16 base 4 = x\\\\16=4^{x} \\4^{2} =4^{x} \\[/tex]

The base will cancel out

2=x          

30) Log 1/216 base 6

[tex]\frac{1}{216} = 6^{x} \\\216^{-1} =6^{x} \\6^{(3)(-1)} =6^{x} \\6^{-3} =6^{x}[/tex]

The base will cancel out

x=-3

Use the definition of absolute value to rewrite each equation or inequality.

[tex]|x| = \begin{cases} x & \text{if } x\ge0 \\ -x & \text{if }x < 0 \end{cases}[/tex]

1. (E) From the definition it follows that

[tex]x-4 \ge 0 \implies |x-4| = x-4 = 8 \implies x = 12[/tex]

[tex]x-4 < 0 \implies |x-4| = -(x-4) = 4-x = 8 \implies x = -4[/tex]

Then the solution set contains exactly 2 elements, and we write it as shown in choice (E), [tex]x\in\{-4,12\}[/tex].

2. (D) We solve the inequality in essentially the same way as in (1), we just need to keep track of the direction of the inequality.

[tex]x-4\ge0 \implies|x-4|=x-4\ge8 \implies x\ge12[/tex]

[tex]x-4<0 \implies|x-4|=4-x\ge8 \implies x\le-4[/tex]

Note the inclusion of [tex]x=12[/tex] and [tex]x=-4[/tex]. We write this as a union of two half-closed intervals, [tex]x\in(-\infty,-4]\cup[12,\infty)[/tex].

3. (C) This follows from the same steps as in (2). This time the inequality is strict, so we exclude the endpoints and with open intervals write [tex]x\in(-\infty,4)\cup(12,\infty)[/tex].

4. (A) Since [tex]|x|[/tex] always returns a non-negative number, any real number [tex]x[/tex] satisfies the inequalty [tex]|x-4|<\infty[/tex]. We write the solution set as the entire real line, [tex]x\in(-\infty,\infty)[/tex].

5. This leaves us with (B) for the last solution set. This inequality is complementary to the one in (3), which means the solution set to [tex]|x-4|\le8[/tex] is the complement of the set we found in (3). That interval removes everything between and including -4 and 12 from the real line. So the solution in this case is what we omit from the solution to (3), and we write [tex]x\in[-4,12][/tex].

One of the digit is 4

So, let the value of x = 4

Putting the value of x in eq-1

4 + y = 5

y = 5 - 4

y = 1

Since tens placed number block is a greater than the ones block,

y > x

Answer: Average velocity = 11.1 m/s

Step-by-step explanation:

Given data,

A baseball is tossed up into the air at an initial velocity = 16 m/s​.

The height of the baseball at time t​ in seconds is given by,

                            h(t) =  16t - 4.9t²  ​​(in meters).

So,  

The average velocity is,            

To calculate the velocity travelled by the ball, differentiate the function.

                           dh/dt = 16 - 2(4.9t)

                           dh/dt = 16 - 9.8t               (eq-1)

Let us assume,    t = [1,1.5]​

Substitute t for 1 in the above Differential function

                            dh/dt = 16 - 9.8 (1)

But ,

                           dh/dt = velocity

So,                     dh/dt = V                        

                          V = 16 - 9.8

                          V =  6.2 m/s

Therefore,

               Average velocity = ( U + V ) / 2

               Average velocity = (16 + 6.2)/2

               Average velocity = 22.2/2

               Average velocity = 11.1 m/s

Hence, Average velocity = 11.1 m/s.

The results for the connected graph H, obtained by using graph theory are;

First part;

There are 22 vertices in the spanning tree

Second part;

There are 22 vertices in H

Third part;

D. H has at least 21 edges

The given parameters are;

H = A connected graph

Number of edges in the spanning tree of H = 21

First part

Required:

The number of vertices in the spanning tree of H

Solution;

In graph theory, a spanning tree is one that contains all the vertices of the graph.

The number of edges in a tree that has n vertices is 'n - 1'

Therefore;

Number of edges = n - 1 = 21

n = 21 + 1 = 22

Second part;

From the definition of a spanning tree, the number of vertices in H is equal to the number of vertices in the spanning tree which is 22

Third part;

Let m represent the number of edges in H.

Therefore, the number of edges that should be deleted from H to get the spanning tree is 'm - (n - 1)', which gives;

The number of edges in the given spanning tree is n - 1 = 21

The roots of the quadratic equation 4x² - 2x - 20 = x² + 9x are x = 5 and

x = - 7/6 respectively.

We have the following equation -

4x² - 2x - 20 = x² + 9x

We have to find its roots.

A quadratic equation is an algebraic equation of the second degree in x. In the standard form it can be written as ax² + bx + c = 0. In this - a and b are the coefficients of 'x' and 'x²' respectively and c is a constant term.

According to the equation -

4x² - 2x - 20 = x² + 9x

4x² - x² - 2x - 9x - 20 = 0

3x² - 11x - 20 = 0

Using quadratic formula, the roots of the equation will be -

x = (- b ± [tex]\sqrt{b^{2} - 4ac}[/tex]) / 2a

x = (11 ± 19)/6

x = 30/6   and  x = -7/6

x = 5  and  -7/6

Hence, the roots of the quadratic equation are 5 and -7/6.

Answer:

The domain of this function is (in order of least to greatest) is [-2,-1,0,3.5,4,5.5, and 8]

The range of this function is (in order from greatest to least) is [6,5.5,4,0,-1, and -3.5]

Step-by-step explanation:

To find the domain you need to look at all of you input or x values so the question is asking to name the values of x for your domain. You look at the table to where x is and name the numbers listed in this case it's [-2,-1,0,3.5,4,5.5, and 7]

To find the range you need to look at the listed outputs or y values. You are essentially doing the same steps but instead you looking at y for the listed values. Generally when it comes to domains that have the same range (for example (4,-1) and (5.5,-1)) you would only write it once in the list of ranges so like [6,5.5,4,0,-1, and -3.5]

Answer:

-4×(2×1)=8x-2-4

-6=8x

divide -6 to 8 and you will get the answer

x=-0.75

Answer:

x = -0.25 (or) -1/4

Step-by-step explanation:

Let's solve the problem,

→ -4 × (2 × 1) = 8x - 2 - 4

→ -4 × 2 = 8x - 6

→ -8 = 8x - 6

→ 8x = -8 + 6

→ x = -2/8

→ [ x = -0.25 ]

Thus, solution is -0.25.
