A number y is rounded to 2 decimal places

1 answer:

3 0

Y can be rounded up to 1.51 from a minimum value of 1.505
This is the lower bound.

y can be rounded down to 1.51 from a maximum value of 1.515
this is the upper bound.

y is between the lower bound and the upper bound so y is between 1.505 and 1.515

This is shown as 1.595<=y<1.515

<= is the typed out version of (greater than/equal to) which is < with a line under it.

Rob buy 6 tickets to the basketball game he pays $8.50 for parking. His total cost is $40.54. What is the cost of each ticket?

Natalija [7]

The cost of all the tickets is 32.04

Subtract $8.50 from $40.54 to leave you with the ticket costs.

Each individual ticket would be 5.34. You get this because $32.04 divided by six tickets is the cost of one.

Which of the following statements is true?

Schach [20]

Answer:

Over the interval [0, 2], the average rate of change of f is greater than that of g. The y-intercept of f is the same as the y-intercept of g.

Step-by-step explanation:

The function i.e mentioned in the question is

$f(x)=5^x-4$

Now Placing x = 0, to compute the y-intercept

$f(0)=5^(0)-4=1-4=-3$

f(x) y-intercept is -3

As we can see in the given graph the graph of g(x) intersects the y-axis at -3

Therefore the y-intercept of g(x) is -3.

Hence, both functions with respect to the y-intercepts i.e f(x) and g(x) would remain the same

Now At x=2,

So, the value of the function is

$f(2)=5^2-4=25-4=21$

The average rate of change of f over the interval [0,2] is

$m=\frac{f(2)-f(0)}{2-0}$

$m=\frac{21-(-3)}{2}=12$

From the mentioned graph as we can see that the graph of g(x) is crossing through the points (0,-3) and (2,12).

The average rate of change of g over the interval [0,2] is

$m=\frac{g(2)-g(0)}{2-0}$

$m=\frac{12-(-3)}{2}=7.5$

Therefore this is the correct answer but the same is not provided in the given options

How do you estimate an irrational vsquare root? Use COMPLETE sentences! Make sure you use LOTS of details. Word Bank Square Root

suter [353]

Answer:

Step-by-step explanation:

Lets illustrate one method by an example:

Find the square root of 12:

The 2 perfect squares around 12 are 3^2 and 4^2 so the square root of 12 is going to be between 3 and 4.

We might predict it to be 3.5

If we square 3.5 we get 12.25 so we are pretty close.

It is less than 3.5 so we might try 3.4 .

Working 3.4^2 out we get 11.56 so we know the square root is between 3.4 and 3.5 Since 12.25 is closer to 12 than 11.56, the square root is closer to 3.5 than 3.4 so we might try 3.46.

This is called the method of trial and improvement and requires you to do long multiplications.

If A = (7,9) and B = (3 , 12) what is the length of AB

V125BC [204]

Answer:

AB = 5 units

Step-by-step explanation:

Calculate the length using the distance formula

d = $\sqrt{(x_{2}-x_{1})^2+ (y_{2}-y_{1})^2$
