Hope this is helpful :)

Answer:

has three terms. The first term has a degree of 5 (the sum of the powers 2 and 3), the second term has a degree of 1, and the last term has a degree of 0. Therefore, the polynomial has a degree of 5, which is the highest degree of any term

Answer:

Step-by-step explanation:

Your average rate is 36.7 miles per hour over nine hours

Average speed is defined as the ratio of the total distance traveled by a body to the total time taken for the body to reach its destination.

In the first 4 hours, you've averaged 33.75 miles per hour, but this is apparently not sustainable, since at 9 hours you've only averaged 36.7 miles/hour.

You continue driving, and calculate that after driving 8 hours you are 255 miles from Seattle. you've averaged 31.8 miles per hour

So the answer is that your average rate is 36.7 miles per hour over nine hours, although you did manage a faster burst of 50 mph for four hours once.

Answer:

D - No, the ordered pair (4,9) is a solution to this problem.

Step-by-step explanation:

If you plotted the number of snacks as the x-axis, and then the total cost of the snacks on the y-axis, you would be able to graph a line and see the cost of snacks based on the number purchased. If you were going to write an equation for this, it would be y=2.25x (or y = 2 1/4 x)

In this case, as each snack is the same price, the y-values for each x would be as such: (1, 2.25) <- one snack, $2.25;

(2, 4.5)

(3, 6.75)

(4, 9)

So that is why the ordered pair of (4,9) would be a solution to this problem.

Hope that makes sense!

The [tex]\sqrt{7}[/tex] is just like an x variable at this point because they are both the same. If it was [tex]\sqrt{7}[/tex] and [tex]\sqrt{14}[/tex] for example, then you wouldn't be able to subtract them so easily.

Answer:

We know that Salma will run less than 35 miles in total this week.

So if t represents the number of miles that Salma runs, we have the inequality:

0mi ≤ t < 35 mi

(where the first part comes because she can not run a number of negative miles, but this is trivial.)

We know that she already ran 18 miles, then we have now the inequality:

t + 18mi < 35mi

Now we need to isolate S

t < 35mi - 18mi

t < 17mi

So she can run any number of miles that is smaller than 17 miles.

For example, she could run 10 miles, 14 miles, 4.5 miles, etc.

Answer:

First, you have to find out the words per second.

2 and 3/5 min = 165 sec

165 sec divided by 110 words = 0.6 words a second

4 and 1/4 min = 255 sec

0.6 x 255 = 153 words in 4 and 1/4 min

Answer:

x = 11 / x = - 4

Step-by-step explanation:

x² - 7x - 34 = 10

x² - 7x - 34 - 10 = 10 - 10

x² - 7x - 44 = 0

x² + 4x - 11x - 44 = 0

x (x + 4) - 11 ( x + 4) = 0

(x - 11)(x + 4) = 0

(x - 11) = 0 / (x + 4) = 0

x = 11 / x = - 4

Answer:

x=t-p

Step-by-step explanation:

just move p to the other side and since it crosses the equals sign so you have to change it from positive to negative

Answer:

x=t-p

Step-by-step explanation:

To make x the subject of the formula, you’d have to take p to the other side. And when (+p) crosses over to the other side, it changes to (-p) because of the equality sign.

Answer:

The axis of symmetry for the graph of y = -2x² + 16x - 7 will be:

x = 4

Hence, the last option i.e. x = 4 is the correct option.

Step-by-step explanation:

Given the equation

[tex]y\:=\:-2x^2\:+\:16x\:-\:7[/tex]

For a parabola in standard form y = ax² + bx + c

The axis of symmetry is the vertical line that goes through the vertex x = -b/2a

so

The axis of symmetry for y = ax² + bx + c is x = -b/2a

In our case,

[tex]a=-2,\:b=16[/tex]

Therefore,

x = -16/2(-2)

x = -16 /-4

x = 16/4

x = 4

Therefore, the axis of symmetry for the graph of y = -2x² + 16x - 7 will be:

x = 4

Hence, the last option i.e. x = 4 is the correct option.

The required value of the given percentage is 16. "125%" represents 125 parts out of 100, which is equivalent to 1.25 times the original value.

To find 125% of 12.8, we can multiply 12.8 by 1.25.

First, we convert the percentage to decimal form by dividing it by 100. So, 125% becomes 1.25.

Next, we multiply 12.8 by 1.25:

12.8 × 1.25 = 16.

Therefore, 125% of 12.8 is 16.

Multiplying 12.8 by 1.25 increases it by 25% or adds one-quarter of the original value. Thus, the result of 16 represents an increase of 25% from 12.8.

Thus, the required value of the given percentage is 16.

Given:

The graph of a line which represents position (m) at time (s).

To find:

The slope of the line.

Solution:

Formula for slope:

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

From the given graph it is clear that the line passes through two points (0,0) and (1,4).

Using the above formula, we get

[tex]m=\dfrac{4-0}{1-0}[/tex]

[tex]m=\dfrac{4}{1}[/tex]

[tex]m=4[/tex]

Therefore, the slope of the line is  4 m/s.

Answer:

The number of branches triples every 15 years.

Step-by-step explanation:

Satoshi started studying how the number of branches on his tree grows over time.

The relationship between the elapsed time t, in years, since Satoshi started studying the tree, and the number of its branches, N(t), is modeled by the following function:

N(t) = 24 - 3^t/15

Complete the following sentence about the growth rate of the branches. The number of branches triples every years.

The number of branches triples every 15 years.

Given is that the relationship between the elapsed time [t], in years, since Satoshi started studying the tree, and the number of its branches [N(t)], is modeled by the following function → N(t) = 24 - 3^t/15

The function that models the situation is -

N(t) = 24 - 3ⁿ/15    .... Eq[1]

After tripling the number of branches, we can write -

3N(t) = 24 - 3ⁿ/15

N(t) = {24 - 3ⁿ/15}/3     ..... Eq [2]

Equating both equations, we get -

{24 - 3ⁿ/15} = {24 - 3ⁿ/15}/3

3{24 - 3ⁿ/15} = {24 - 3ⁿ/15}

72 - 3ⁿ/5 = 24 - 3ⁿ/15

72 - 24 = 3ⁿ/5 - 3ⁿ/15

48 = 3ⁿ(1/5 - 1/15)

n = 15

Therefore, the number of branches triples every 15 years.
